The distribution box is assembled according to the requirements of electrical wiring. The switchgear, measuring instrument, protective appliance and auxiliary equipment are assembled in a closed or semi-closed metal cabinet or on the screen to form a low-voltage power distribution device. Here is a small series of decoration home decoration network to introduce to you what is the stainless steel distribution box and stainless steel distribution box how to connect, I hope to help everyone understand more about stainless steel distribution box , let everyone on the stainless steel distribution box No longer strangers.
First, what is a stainless steel distribution box
In normal operation, the circuit can be switched on or off by means of a manual or automatic switch, and the circuit or alarm can be cut off by means of a protective device during faulty or abnormal operation. The measuring instrument can display various parameters during operation, and can also adjust some electrical parameters to prompt or signal the deviation from the normal working state. Commonly used in various hair, distribution, and substation. Classified by structure and purpose:
1. Fixed panel switchgear, often called switchboard or power distribution panel. It is an open switchgear with panel covering, the front side has protective effect, the back and side can still touch the live part, the protection level is low, and can only be used for industrial and mining enterprises with low power supply continuity and reliability requirements. The transformer room is used for centralized power supply.
2, protective (ie closed) switchgear, refers to a low-voltage switchgear that is closed except for the mounting surface. Electrical components such as switches, protection and monitoring controls of such cabinets are mounted in a closed enclosure made of steel or insulating material, mounted on a reliable wall or off the wall. There may be no isolation between each circuit in the cabinet, or it may be isolated by a grounded metal plate or insulating plate. Usually the door is mechanically interlocked with the main switch operation. There is also a protective table type switchgear (ie console) with controls, measurements, signals and other electrical appliances. The protective switchgear is mainly used as a power distribution unit at the process site.
3. Drawer type switchgear. This type of switchgear is made of steel plate and closed, and the electrical components of the inlet and outlet circuits are installed in drawers that can be extracted to form a functional unit that can perform certain types of power supply tasks. Between the functional unit and the busbar or cable, it is separated by a grounded metal plate or a functional board made of plastic to form three areas of busbar, functional unit and cable. There are also isolation measures between each functional unit. Drawer type switchgear has high reliability, safety and interchangeability. It is a relatively advanced switchgear. Most of the switchgears currently produced are drawer type switchgear. They are suitable for industrial and mining enterprises and high-rise buildings that require high reliability of power supply as a centralized control distribution center.
4. Power and lighting distribution control box. Mostly closed vertical installation. The degree of protection of the enclosure varies depending on the application. They are mainly used as power distribution devices at the production sites of industrial and mining enterprises.
Second, how to connect stainless steel distribution box
The identification of the incoming line's live line is the identification of the L-line. The general-purpose stainless steel distribution box consists of a main switch and a number of powder line switches. Generally, the main switch is mostly equipped with a leakage protection function. When the wiring is connected, the fire line is connected with red. Line trace, the neutral line is blue, black, or yellow. If it is a single-switch power distribution switch, it must be connected to the live line. If you install a stainless steel distribution box for your home, you need to purchase the entrance line. The choice of four square meters is almost the same. Connect the fire switch to the main switch switch of the household through the live wire in the leakage switch, and connect the switch to each room through the fire line. The zero line is common and separates into each room. Before installing the household stainless steel distribution box, be sure to buy the equipment involved, then measure the rated current of the household circuit and the working voltage. Configure a similar stainless steel distribution box according to the power supply of the household circuit, and then Then design a wiring diagram of the household stainless steel distribution box, through the connection diagram of the household stainless steel distribution box, so that the whole process goes down and the installation is very convenient. The range of electrical box applications is different, then the wiring method is different. The wiring diagram of the household stainless steel distribution box is relatively simple, and the wiring diagram of the household stainless steel distribution box in the building or power plant is more specialized.
Through a brief introduction to the above article, Xiaobian believes that everyone has already got a certain understanding of what is the stainless steel distribution box and the stainless steel distribution box. I hope that the introduction of Xiaobian can help to understand the stainless steel. The mass of the electric box.
