Why do hydropower reforms
New houses come to life to renovate old houses. We inevitably need to carry out hydropower reforms. The so-called hydropower reform refers to the renovation of all or part of the circuit used by the original developers according to the decoration configuration, family population, living habits, and aesthetic concepts. Process. Hydroelectric reform is divided into waterway reconstruction and circuit reconstruction. So, why do we have to install and reform hydropower?
The answer is very clear. As far as new houses are concerned, developers' installations of indoor waterways and circuits are only installed according to general requirements, and the number is not large. Therefore, before entering new houses, new houses and hydropower should be reconstructed according to the needs of household life and living habits; in addition, the hydropower materials used by developers may be more general, as long as they pass the inspection and acceptance, and can pass water to power when the building is opened. Therefore, from the perspective of ensuring the safety of use in the future and prolonging the service life, it is necessary to carry out hydropower reform on new houses.
However, if the old house is refurbished, due to the use of the old house for a period of time, the water and electricity lines may be subject to aging, water leakage, etc. due to various reasons. Therefore, from the perspective of safety, it is necessary to reconstruct the water and electricity of old houses and eliminate potential safety hazards; in addition, after staying in an old house for a period of time, the circuit of the house may be needed for various reasons, such as the increase of electrical appliances. As the waterway is increased or adjusted, it is also necessary to carry out partial or overall reconstruction of the old house's hydropower.
Hydropower installation precautions:
1. Before the construction, there must be electrical (strong, weak), water supply and drainage design and construction drawings.
2. It is forbidden to lay the conductor directly in the wall, floor, under the floor or ceiling without any protection.
3, different voltages, different loops, different signal lines are strictly prohibited to wear in the same threading tube.
4, the installation of lamps should be done after the paint is completed. 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. The switch of the lamp and electrical equipment must be installed on the "phase line" (ie, the control phase line), otherwise, the switch off, the light off and the electrical equipment is still energized, and it is easy to cause electric shock.
6. There are two protection methods for the power system: ground protection and zero protection. At present, China generally adopts the ground protection method. Note that in the same system, it is forbidden to adopt two protection methods at the same time, otherwise it 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.
8. The interface of each line should be smooth and the connection between the plates should be firm. The power inlet box interface box should be protected by a protective ring (lock nut).
