The air switch, literally understood as the air circuit breaker, not only has the function of the control circuit, but also has the function of the protection circuit. If the current in the circuit is too large, it will automatically turn off the power switch and protect the electrical equipment and voltage equipment. Then, how to connect the air switch ? Air switch installation What are the precautions? Let the small series for everyone to introduce how to connect the air switch and the air switch installed what precautions!
First, how to connect the air switch?
1. The air switch is divided into three-phase power and single-phase power. Generally, there is only one fire wire and one neutral wire for single-phase power, and the single-phase power is for home use. Then, three fire lines or three fire lines are the three-phase electricity, and three-phase electricity is the industrial electricity.
2. When we install the air switch, we must turn the word of the air switch upwards. The area above the word should enter the line, and the place below the word should have the line. Generally, there is an “N†at the entrance of the left side of the single-phase power. The mark indicates that the mouth is in the zero line, and the other one is the line of fire.
3, under what circumstances to buy three-phase air open it? In the case of only three FireWire or three FireWire and a zero line, we have to buy a three-phase power of the open, three-phase power of the open and there are only three Into the line of fire entrance, if there is a left of the zero line do not have to open the air, directly received electricity appliances, three fire lines still into the air after the out of the electrical appliances.
4. In order to create a safe electricity environment, we can use a double-gate switch with leakage protection and three single-switch air switches as controls.
Second, the air switch installation what precautions
1. Before we install the air switch, we must check what kind of power supply we are using. Simply put, it is to check what power your appliance is. If the electrical power does not match the switch live wire, it may not be installed.
2. After we have determined the power of the distribution box, we can buy the corresponding air switch and select it according to the number of firewires. We call a FireWire 1P, this applies to 220V low-power electrical appliances; a FireWire a neutral line called 2P, suitable for 220V motor; then the three FireWire is 3P, for 380V appliances .
3, under normal circumstances, the air switch and distribution box can be used to connect. If there is no distribution box, you can use a fixed air switch slot instead. Fix the card slot to the wall or wood and install the air switch on the card slot.
The above is all about the air switch and how to install the air switch . It is hoped that it will help everyone. If you want to know more relevant knowledge, you can continue to pay attention to the relevant information of this website. Xiao Bian will bring more exciting content for everyone.
