The first stage power supply lightning protector three phase lightning protection
Product Details
Surge protector is the lightning protection measures taken by Zhejiang toer Electric Co., Ltd. for the electrical system. It provides electronic equipment for all kinds of electronic equipment, instruments and communication lines. When overvoltage is generated, the effect of shunting and voltage limiting can be achieved. To prevent excessive current and voltage damage to equipment, play the role of protection devices.
Use of attention
1. in order to limit the inductive coupling between the protected part after installation and the part of the unprotected equipment, we need to make some measurements. The mutual inductance can be reduced by the separation of the inductive source and the sacrificial circuit, the selection of the loop angle and the limitation of the closed loop area.
2. identify the input / output interface identifier of the lightning protector, input the external line and output the connection device.
3. it should match the working voltage of the protected equipment. Please install according to the installation sketch.
Product features
1. multi-functional overvoltage protection, lightning and overpressure are no longer afraid of disasters.
2. self protection voltage is more than self protection, automatic disconnection and recovery.
3. safety insulation of fire retardant and high flame retardant material
Product Installation
With 35mm standard DIN-rail mounting, connecting copper stranded conductor is 2.5~35mm²
At front of spd each pole must be setted protection---used fuse or miniature circuit breaker lightning current SPD protection,after SPD breakdown to short circuit protection.
SPD install on protected line(equipment) to the front and connected to the supply line. A class products install in the building home-entry line hold larger surge current total distribution box. B, C class products most install on the floor distribution box, D class products close to the front-end equipment that smaller surge current, smaller residual voltage place.

Working principle of product
In the equipment system, the inductive or capacitive coupling voltage is caused by the lightning shock and the switching operation of the upstream power supply system. Therefore, the surge may damage the photovoltaic modules and inverters and other devices. This will cause serious consequences for the operation of the system. The surge protector is a DC power defense specially designed for this purpose. The lightning module, once the high voltage, and endanger the insulation of the protected equipment, the lightning arrester acts immediately, the high voltage impact current guide the earth, thus limiting the voltage amplitude, protecting the insulation of the equipment. When the overvoltage is gone, the arrester is restored to its original state quickly, so as to protect the power equipment.
