Question:
the old floor, second-hand housing, electricity system has not been modified, power outlets are an outlet on the wall are two, no three-headed ground.
As recently purchased a high-powered water heaters, installation of people are not really understand them, directly Jiuji stuck. Recently, however, often see water heater accident, did not know how to transform in the end need to be safe?
is to transform the power outlet inside the wall do? On the inside leads to a line to ground?

Answer:
past old buildings there is no ground wire, and only single-phase AC electric zero-line and FireWire, using two socket holes. With the popularity of home appliances, water heaters, refrigerators, air conditioners, electric fans, hair dryer, washing machines, computers, etc. into the home. In order to use the safety of these appliances should be connected to a reliable ground. Television sets, disc players, video recorders, plastic fans, like two feet of electrical power plug, do not have ground wires.
Please take note of the power capacity of the table, the previous 5 (10) A meter is no longer applicable, it should be for maximum current of 20A and above. Can not just change meter, but also for indoor wire at the same time to “expansion”, for use thicker wire (old house fires caused by power line is quite prone).
ground in the bottom corner edge, with 1.5 meters above the angle iron into the ground, and then from the above ground wire leads to the indoor.

Answer:
you first make sure your home into the family line is Jigen, if there is a single-phase power into three lines coming in, then said into the family line have safety ground wire, and if not, then it only to re-take a new earth, and do not put the power cord leads to ground Oh! If you are a high-rise tenants, then tell you that one is economical and convenient method is to beams in your home, or stigma, Zhuo a hole where it is estimated that steel Zhuo Oh! To go after the receipt of the above cited lines (as long as they are received on the first floor of stigma are reinforced underground, absolutely reliable, not dangerous). But you quoted that line must be connected, handle the security until

Answer:
for a slightly Hehe

not difficult

Answer:
you say grounding wire is actually static electricity into an underground electrical items, and households-line has nothing to do, remember that 10 million households do not take this two-line chaos, otherwise it will cause an accident.

Chinese:两头的插座怎样接地？电工达人说一下，谢谢

类别: 电力

问题:
老楼的二手房，用电系统一直没有改造，电源插座都安在墙上都是两头插座，没有三头的接地。
由于最近新购买了大功率的热水器，安装的人也不是很懂，直接就给插上了。可是最近常看到热水器事故，不知道到底需要怎样改造才能安全？
是要改造墙里面的电源插座吗？在里面引出一根线来接地？

回答:
　　以前老式楼房是没有接地线的，只有单相交流电的零线及火线，使用两孔插座。随着家用电器的普及，热水器、冰箱、空调、电风扇、电吹风、洗衣机、电脑等等进入家庭。为了使用的安全，这些电器都要接上可靠的地线。电视机、碟机、录像机、全塑电扇之类两脚电源插头的电器，都不用接地线。
　　请注意一下所用电表的容量，以前的5(10)A电度表已不适用，应该换{zd0}电流20A及以上的。不能光换电表，还应同时对室内电线进行“扩容”，换用较粗的导线(老式房子电源线引起的火灾还是比较多发的)。
　　地线可在底层的墙角边，用1.5米以上的角铁打入地下，再从上面引出接地线到室内。

回答:
你首先要确定你家进户线是几根，如果是单相电有进三根线进来的话，那么表示进户线就有安全接地线，如果没有的话，就只有重新接一条新的地线了，千万不要把电源线引出来接地哦！如果你是高层住户的话，告诉你个既经济又方便的方法，就是在你家的梁或者柱头上，琢一个洞，估计有钢筋的地方才琢哦！之后就引条线去接到上面（因为只要是柱头都是钢筋接到一楼地下的，{jd1}可靠，没危险的）。但是你引的那线一定要接好，处理好，安全为止

回答:
换一个咯 呵呵

不难的

回答:
你所说的接地线其实就是将电器的静电引入地下,与入户线无关,记住千万不要将入户这两根线乱接,否则会引发事故.
