卫生间局部等电位作法 One: 卫浴间等电位详细介绍 一、住宅卫浴间应配等电位 根据最新《住宅》规定,住宅卫浴间内应作等电位联结。然而在实际调查显示,有七成业主家中无安装等电位装置。尽管是法规规定内容,但等电位联结保护的市场普及率非常低,甚至许多业主都不知道等电位的概念。 二、安全卫浴间等电位的概念 等电位就是电位相等,如果电位不相等,就有电位差即电压,加上卫浴潮湿的环境下,人很可以被用电设备和外露的金属电击。因此将卫浴间内的电器装置、金属物件以及可导电的部分全部用导体联结起来,减小电位差以消除危害,这就是卫浴间安装等电位的作用。 三、等电位能防御雷击感应电 equipment, components, equipment, temporary construction facilities, processed with strict compliance with provisions of construction floor plans, smooth roads and drainage, site formation. ----3, the site looks dignified and elegant and tidy, advertising slogans to write eye-catching appearance, walls to be clean and tidy. 4, "six-second figure"----cards to complete, custom, eye-catching, hanging in the obvious place. Management----5, district administration, "launch of Qing dynasty" focuses on managing the "cleaning, recycling, use," four Central Bank; the work is finished, clean, clear, work product protection in all procedures to periodically check the appraisals in a timely manner. 6, clean health----engineering work sites, temporary facilities clean and tidy inside and outside. 7, mechanical health----engineering machinery, vehicles are maintained in good condition, looks clean, and free from dirt, dust, electrical switchgear (box) complete with lock, mechanical safety protection equipment and complete, sensitive and reliable. 8, fire, defend----perfect fire system, set in accordance with requirements of fire equipment, set up obvious fire safety signs and signage, provide effective fire-fighting equipment, establishment of a security system, and out of the site staff to wear to work, marks and signs, implements 雷雨天气,建筑物遭受雷击,楼内所有金属物体都会产生感应电,尤其是卫生间里的 下水管、暖气管。这时在卫生间里洗澡,万一触碰金属物体就会被感应电袭击。如果 有了等电位,遭受感应电袭击的概率就会大大降低。 四、等电位需由业主请人安装 equipment, components, equipment, temporary construction facilities, processed with strict compliance with provisions of construction floor plans, smooth roads and drainage, site formation. ----3, the site looks dignified and elegant and tidy, advertising slogans to write eye-catching appearance, walls to be clean and tidy. 4, "six-second figure"----cards to complete, custom, eye-catching, hanging in the obvious place. Management----5, district administration, "launch of Qing dynasty" focuses on managing the "cleaning, recycling, use," four Central Bank; the work is finished, clean, clear, work product protection in all procedures to periodically check the appraisals in a timely manner. 6, clean health----engineering work sites, temporary facilities clean and tidy inside and outside. 7, mechanical health----engineering machinery, vehicles are maintained in good condition, looks clean, and free from dirt, dust, electrical switchgear (box) complete with lock, mechanical safety protection equipment and complete, sensitive and reliable. 8, fire, defend----perfect fire system, set in accordance with requirements of fire equipment, set up obvious fire safety signs and signage, provide effective fire-fighting equipment, establishment of a security system, and out of the site staff to wear to work, marks and signs, implements 等电位装置通常由开发商预留,但是需要专业师傅安装,包括配套设施可能需要业主另外购买。在电气设备普遍进入卫浴的今天,安装等电位可是关乎生命安全的一份保障,新居业主们应该主动向专业装修工咨询。 Two:卫浴等电位的常见误区 等电位安装比较专业,需要由有经验的电工负责。而业主如果事先了解了相关的知识,能够尽量减少施工误区,降低家居安全威胁。 误区一:任何卫浴间无需做局部等电位联结 不少人认为卫生间用电器具已经通过PE线接地,并有漏电保护器保护,所以金属器具无须做局部等电位联结。 equipment, components, equipment, temporary construction facilities, processed with strict compliance with provisions of construction floor plans, smooth roads and drainage, site formation. ----3, the site looks dignified and elegant and tidy, advertising slogans to write eye-catching appearance, walls to be clean and tidy. 4, "six-second figure"----cards to complete, custom, eye-catching, hanging in the obvious place. Management----5, district administration, "launch of Qing dynasty" focuses on managing the "cleaning, recycling, use," four Central Bank; the work is finished, clean, clear, work product protection in all procedures to periodically check the appraisals in a timely manner. 6, clean health----engineering work sites, temporary facilities clean and tidy inside and outside. 7, mechanical health----engineering machinery, vehicles are maintained in good condition, looks clean, and free from dirt, dust, electrical switchgear (box) complete with lock, mechanical safety protection equipment and complete, sensitive and reliable. 8, fire, defend----perfect fire system, set in accordance with requirements of fire equipment, set up obvious fire safety signs and signage, provide effective fire-fighting equipment, establishment of a security system, and out of the site staff to wear to work, marks and signs, implements 正解:局部等电位联结和漏电保护器是两种不同的安全保护,不能互相代替。等电位的作用是为了保证某电位基本相等,不至于产生较大电压伤害人体。而地线的作用是保证漏电部位与大地之间的电阻相对较小,从而保证流经人体的电流较小。一个是保证电压较小,一个是保证电流较小。 误区二:只要是卫浴就得做局部等电位 人体洗浴时人体阻抗会降低,在卫浴间特备容易触电。如果浴室安装了电热水器、或配置了若干用电设备,浴室必须做局部等电位联结。而对于一些传统的既无电热水器,又无添置电器的卫浴间,可根据情况决定是否做局部等电位。 误区三:局部等电位会导致电击事故 局部等电位会将外界的高电压引入室内,造成触电事故,不如将此电位由接地线引入接地装置来得安全。 equipment, components, equipment, temporary construction facilities, processed with strict compliance with provisions of construction floor plans, smooth roads and drainage, site formation. ----3, the site looks dignified and elegant and tidy, advertising slogans to write eye-catching appearance, walls to be clean and tidy. 4, "six-second figure"----cards to complete, custom, eye-catching, hanging in the obvious place. Management----5, district administration, "launch of Qing dynasty" focuses on managing the "cleaning, recycling, use," four Central Bank; the work is finished, clean, clear, work product protection in all procedures to periodically check the appraisals in a timely manner. 6, clean health----engineering work sites, temporary facilities clean and tidy inside and outside. 7, mechanical health----engineering machinery, vehicles are maintained in good condition, looks clean, and free from dirt, dust, electrical switchgear (box) complete with lock, mechanical safety protection equipment and complete, sensitive and reliable. 8, fire, defend----perfect fire system, set in accordance with requirements of fire equipment, set up obvious fire safety signs and signage, provide effective fire-fighting equipment, establishment of a security system, and out of the site staff to wear to work, marks and signs, implements 正解:只要电位相等,不产生电位差,就不会发生电击事故,无需将电位引入接地装置。局部等电位要求在局部区域内接触到的电阻不大于3Ω,只要能将卫浴间贯通成一个等电位体,即使外界有高电压,人在卫浴内触碰不到外界高电压导体,也是安全的。 误区四:用其他测量仪代替等电位测试仪 由于目前市面上的等电位测试仪较少,测量工作中经常遇到用接地电阻测量仪、万用等来代替。 equipment, components, equipment, temporary construction facilities, processed with strict compliance with provisions of construction floor plans, smooth roads and drainage, site formation. ----3, the site looks dignified and elegant and tidy, advertising slogans to write eye-catching appearance, walls to be clean and tidy. 4, "six-second figure"----cards to complete, custom, eye-catching, hanging in the obvious place. Management----5, district administration, "launch of Qing dynasty" focuses on managing the "cleaning, recycling, use," four Central Bank; the work is finished, clean, clear, work product protection in all procedures to periodically check the appraisals in a timely manner. 6, clean health----engineering work sites, temporary facilities clean and tidy inside and outside. 7, mechanical health----engineering machinery, vehicles are maintained in good condition, looks clean, and free from dirt, dust, electrical switchgear (box) complete with lock, mechanical safety protection equipment and complete, sensitive and reliable. 8, fire, defend----perfect fire system, set in accordance with requirements of fire equipment, set up obvious fire safety signs and signage, provide effective fire-fighting equipment, establishment of a security system, and out of the site staff to wear to work, marks and signs, implements 正解 :用除了等电位专用测试仪以外的测量仪器都是错误的。绝缘电阻测试仪虽能测试其导通性,但测量低于3Ω的等电位的电阻则不行。万用表的测量电流通常较小,不满足国家规定的检测电流不小于0.2A的要求。为了防止安全隐患,必须采用专用测试仪进行测试或者采用伏安法测量。 Three: 重视细节 等电位施工及验收规范 了解了卫浴间等电位的重要性以及关于等电位的一些认识误区,下面我们来看看卫浴间等电位安装施工的注意事项。 一、卫浴间等电位施工要求 进行卫浴间局部等电位联结时,必须将金属给排水管、金属浴盆、金属采暖管和地面钢筋网通过电路联接到等电位端子板上。当墙为混凝土墙时,墙内钢筋网也宜与等电位联结线连通。金属地漏、扶手、浴巾架、肥皂盒等孤立之物可根据情况是否做等电位。 二、等电位端子箱安装位置 equipment, components, equipment, temporary construction facilities, processed with strict compliance with provisions of construction floor plans, smooth roads and drainage, site formation. ----3, the site looks dignified and elegant and tidy, advertising slogans to write eye-catching appearance, walls to be clean and tidy. 4, "six-second figure"----cards to complete, custom, eye-catching, hanging in the obvious place. Management----5, district administration, "launch of Qing dynasty" focuses on managing the "cleaning, recycling, use," four Central Bank; the work is finished, clean, clear, work product protection in all procedures to periodically check the appraisals in a timely manner. 6, clean health----engineering work sites, temporary facilities clean and tidy inside and outside. 7, mechanical health----engineering machinery, vehicles are maintained in good condition, looks clean, and free from dirt, dust, electrical switchgear (box) complete with lock, mechanical safety protection equipment and complete, sensitive and reliable. 8, fire, defend----perfect fire system, set in accordance with requirements of fire equipment, set up obvious fire safety signs and signage, provide effective fire-fighting equipment, establishment of a security system, and out of the site staff to wear to work, marks and signs, implements 等电位端子箱安装于卫浴间室内,一般埋入贴砖中即可,电路方面墙内地下铺设导线 必须使用塑料管道作保护。如果对卫浴捡进行改造须移动内墙时,等电位也需重新改 造。 三、注意卫浴间内是否有PE线 注意卫浴间如果原来没有PE线,局部等电位联结不得与卫生间外的PE线相连,因为 equipment, components, equipment, temporary construction facilities, processed with strict compliance with provisions of construction floor plans, smooth roads and drainage, site formation. ----3, the site looks dignified and elegant and tidy, advertising slogans to write eye-catching appearance, walls to be clean and tidy. 4, "six-second figure"----cards to complete, custom, eye-catching, hanging in the obvious place. Management----5, district administration, "launch of Qing dynasty" focuses on managing the "cleaning, recycling, use," four Central Bank; the work is finished, clean, clear, work product protection in all procedures to periodically check the appraisals in a timely manner. 6, clean health----engineering work sites, temporary facilities clean and tidy inside and outside. 7, mechanical health----engineering machinery, vehicles are maintained in good condition, looks clean, and free from dirt, dust, electrical switchgear (box) complete with lock, mechanical safety protection equipment and complete, sensitive and reliable. 8, fire, defend----perfect fire system, set in accordance with requirements of fire equipment, set up obvious fire safety signs and signage, provide effective fire-fighting equipment, establishment of a security system, and out of the site staff to wear to work, marks and signs, implements PE线有可能因别处的故障而带电位,反而能引入别处的电位。相反如果卫生间内有PE线,则卫生间内的局部等电位联结必须与该PE线相连。 四、局部等电位施工验收 局部等电位联结安装完毕后,应进行导通性测试,测试用电源可采用空载电压为4,24v的直流或交流电源,测试电流不应小于0.2A,若端子板与等电位联结范围内的金属导体之间的电阻不大于3欧姆,可认为等电位联结有效,如发现导通不良,应作跨接线处理。在整个卫浴施工过程中,应始终保证等电位导通。 equipment, components, equipment, temporary construction facilities, processed with strict compliance with provisions of construction floor plans, smooth roads and drainage, site formation. ----3, the site looks dignified and elegant and tidy, advertising slogans to write eye-catching appearance, walls to be clean and tidy. 4, "six-second figure"----cards to complete, custom, eye-catching, hanging in the obvious place. Management----5, district administration, "launch of Qing dynasty" focuses on managing the "cleaning, recycling, use," four Central Bank; the work is finished, clean, clear, work product protection in all procedures to periodically check the appraisals in a timely manner. 6, clean health----engineering work sites, temporary facilities clean and tidy inside and outside. 7, mechanical health----engineering machinery, vehicles are maintained in good condition, looks clean, and free from dirt, dust, electrical switchgear (box) complete with lock, mechanical safety protection equipment and complete, sensitive and reliable. 8, fire, defend----perfect fire system, set in accordance with requirements of fire equipment, set up obvious fire safety signs and signage, provide effective fire-fighting equipment, establishment of a security system, and out of the site staff to wear to work, marks and signs, implements
