Intelligent lightning protection box, single-phase lightning protection, conflux box, distribution room elevator 220V.
Brief introduction
The single-phase power supply lightning protection box lightning protection box module is composed of voltage switch module and voltage limiting module (or integrated MOV). It is mainly installed in the distribution room, the distribution cabinet, the AC distribution screen, the switch box and other important equipment and the power supply line that is easily struck by lightning equipment to protect the equipment from the damage caused by the lightning overvoltage invaded along the power line. It can be widely used in the main power supply of communication, electric power, traffic, finance, railway, civil aviation and other systems. Protection.
Product features
1. remote interface, remote indication of main switch state (optional).
2. double power supply system and up and down access line structure (distribution type lightning protection box has this function).
3. use waterproof, fireproof, moistureproof box

Working principle of product
In the normal working condition, the lightning protection module is in the disconnected state and does not affect the normal work. When the line has the impulse overvoltage at the moment when the lightning strikes, the lightning arrester module quickly passes through the very short time, short the overvoltage to the earth, and when the pulse overvoltage disappears, the lightning arrester module is resumed to disconnect. State, which does not affect the power supply of the user.
Use of attention
1. when the red light is on, it means that the lightning protection parts have been deteriorated or damaged, and need to be repaired.
2. when installing, all connection wires are short, thick, straight and reliable.
3. after installation, close the automatic circuit breaker switch and check whether the working condition is normal.
