人民生活水平的提高,对家庭居室的用电设备要求更高。但由于好多农民住房是自建,对居室的布线、设备安装,大多是自己动手或由农村电工安装,有的因图方便、省事、省料,不注意安全用电有关要求。笔者自退居二线后,邻里、街房、朋友家中电气出了故障,都叫我去帮忙处理,发现其中不少室内电气安装存在问题。为引以为戒,写出来供广大的农村电工参考。1 开关安装高度参差不齐,切合位置不统一 《农村低压电力技术规程》第9.4.4条规定:开关的安装位置应便于操作,同一场所的开关其高度和切合位置应一致,且应控制相线。规程对高度也做了明文规定。开关安装位置过高,不便于操作;而过低一来不便操作,二来小孩易玩弄,既不安全又浪费电能。一般做法应是:如果室内净高低于3.0m时,拉线开关安装位置应距屋顶0.3m;大于3.0m时安装高度为3.0m,且距门框的水平距离为200mm;其它开关(墙装)距地面1.4m,横向距门框300mm的位置。
The improvement of people’s living standards, household appliances on the room more demanding equipment. However, because many peasant housing is self-built, the wiring and equipment installation of the living room are mostly done by themselves or by rural electricians. Some of them are convenient, save trouble and save materials because of their convenience. After I relegated to second line, the neighborhood, street houses, friends at home electrical out of trouble, all told me to help deal with and found that many of the indoor electrical installation problems. To take warnings, write for the majority of rural electrician reference. 1 switch installation height uneven, inconsistent with the position of “rural low-voltage power technology,” Article 9.4.4 states: the switch should be easy to operate the installation location, the same place the switch should be consistent with the height and location, and should control the phase line. Procedures also made explicit provisions on the height. Switch installation location is too high, not easy to operate; and too low to facilitate the operation, and second, children easy to play, neither safe nor wasted power. The general practice should be: If the indoor net height of less than 3.0m, cable switch installation location should be 0.3m away from the roof; more than 3.0m when the installation height of 3.0m, and the horizontal distance from the door frame of 200mm; other switches (wall) 1.4m above ground, horizontally 300mm from the door frame.
