Common wiring methods of plastic meter box and electrical ready board box (Zhejiang Ruixin Electromechanical Co., Ltd.)

Plastic meter box and electrical ready board box manufacturer introduces meter box and electrical ready board box and its connection method

The meter box and electrical ready board box used to produce low-voltage cable tap boxes adopts a resin based composite structure. The box body is made of ABS engineering plastic, transparent PC material and DMC. The four materials of SMC are respectively injection molded.

Summary instrument box

Electricity is a product that consumes energy. With the progress of science and technology and the improvement of people's living standards, the electric charge required by electric power meters is also increasing year by year. In daily production and daily use, if we do not pay attention to the use of electricity, it may also cause disasters. Therefore, understanding the basic safety knowledge of electricity meters is not stressful and can better protect your life and wealth. Next, Lao Wang will explain the common sense about anti-theft of electric energy meter to you, so that you can better understand and use it.

1. Use appropriate fuses. No other wires can be used instead. The function of the fuse is to quickly disconnect the power to ensure the safety of the system when the line is short circuited or overloaded. The current of power supply and instrument shall be considered when selecting fuse.

2. From the capacity of the electric energy meter and low-voltage line, the electric energy that the electric energy meter can withstand is equivalent to the current multiplied by the voltage on it.

3. It is assumed that a socket can be inserted into several electronic devices, and the total total power of the power supply of these devices shall not be greater than the power supply of the power supply.

4. The old instrument shall be submitted to the measuring unit for inspection, sealed with lead after use, and its appearance shall be inspected. If it is new, complete lead seal and factory inspection certificate shall be provided.

5. Periodic inspection of instruments is generally conducted once every three years.

6. Three sockets shall be used for metal housing equipment. When some electrical appliances have problems or are wet, their shells will leak.

7. Each household shall be equipped with a certain number of electronic equipment, such as tester, screwdriver, rubber pliers, etc.

8. Regularly inspect the internal wires and electrical appliances. If they are damaged, immediately wrap them with insulating glue.

9. The instrument must be close to the instrument box, which must be sealed.

10. The instrument shall be dustproof, waterproof and of proper height.

Instrument box connection mode

As we all know, according to the different meters, the meter box and electrical ready board box can be divided into three-phase meter box and electrical ready board box and three-phase meter box and electrical ready board box.

1. Single phase electricity meter box and electrical ready board box: we usually call the 220 V voltage as single phase electricity, which is composed of two conductors: one conductor, one conductor and one zero conductor. For example, our people use it to measure electricity. Putting the instrument in the instrument box is a single instrument box.

2. Connection of single-phase instrument: There are four terminals below the single-phase instrument, from left to right, which are the incoming line, the lead and the zero incoming line

3. The incoming line is the direction of power supply; This is the direction of the wire after it passes through here. The incoming line here is the outgoing line of the upper component: the input line of the instrument is from the main distribution cabinet of the last unit or the switch in the distribution room of the community; The output end of the instrument shall also be a switch, which can be shunted from the household distribution cabinet.

4. Single phase meter box and electrical ready board box: single phase instrument box: circuit breaker, line impact, box. Single phase meter box and electrical ready board box assembled properly according to the power supply circuit diagram
