As we all know, the decoration of hydropower is crucial for every household. Because of the quality of hydropower projects, it directly affects the future quality of life of the owners. Therefore, before the renovation, the owners must understand the knowledge of home- installed hydropower installation through various channels. Here we take a look at home improvement and hydropower should pay attention to what it!
1. Construction drawings before construction
In the knowledge of hydropower installation , there must be electrical (weak and weak), water supply and drainage design drawings before construction.
2 is strictly prohibited exposed wire
It is forbidden to lay the conductor directly in the wall, floor, under the floor or ceiling without any protection.
3 wiring line pipe to distinguish
Different voltages, different circuits, and different signal lines must not be put in the same threading tube.
4. The installation of lamps should be done after the paint is finished
Installing lamps on brick-concrete structures, using wooden wedges, applying hooks, bolts, or expansion bolts, etc. is strictly prohibited. There should be no less than two bolts (or screws) for the fixture. Luminaires must not be installed on combustible components.
5. Lights and electrical equipment switch installation
Lamps and electrical equipment must be installed on the "phase" switch (that is, control the phase line), otherwise the switch off, the light off and electrical equipment is still charged, easy to cause electric shock.
6. The power system has two protection methods
Ground protection and zero protection, China's current general approach is to ground protection. Note that in the same system, you must not use two protection methods at the same time. If you do so, you will cause a safety accident.
7. It is forbidden to use a mobile switch on the bedside
If the fixture is a screw base, the center tongue of the screw base should be connected to the control phase. This knowledge of hydropower installation needs the owners to keep in mind!
8. Protection at the interface
The interface of each line shall be smooth and the connection between the plates shall be firm. The power inlet box interface box should be protected by a protective ring (lock nut).
9. Threading pipe elbow curvature
In order to renew and maintain the conductors in the future, the arc of the elbow buried at the corner of the wall, underground, or ceiling (ie, cold bend radius) should be 5 to 10 times the diameter of the conduit.
10. It is forbidden to connect wires in the conduit
It is forbidden to connect the wire in the conduit. That is, if the length of the wire is not enough, the connector of the wire cannot be in the conduit. Generally, it should be connected in the junction box such as switch, socket and lamp box.
11. Threading tube selection
The threading tube should be selected to have a certain size (thickness), not only to enable the conductor to wear in, but also to leave enough gaps, so that the heat generated by the conductor when passing a large current can be dissipated. The ratio of the cross-sectional area of ​​the general conductor to the cross-sectional area of ​​the conduit is 1/3 to 1/2. It is forbidden for the wire to block the conduit.
12. The water supply pipe can use PP-R pipe and copper pipe.
13. Water supply inspection
The dark water supply pipeline must be strictly inspected whether all the joints are tightly and firmly installed, and the hydraulic pressure is correct. After the water pressure test, the water can be buried for a period of time. The pressure test index is generally between 0.8mpa and 1.0mpa.
The article concludes: In the question of what should be noticed in home- installed hydropower, after reading the knowledge of home- installed water and power installations , is it right? In fact, hydropower installation is a link that owners must control. So everyone must find a superb master of power.
