Surge protector solar 500V pv surge arrester solar SPD 40 KA dc surge protector

Photovoltaic DC surge protector can also be used in thunderstorm days Automatic reclosing leakage protector

Brief introduction

Photovoltaic DC surge protector is a lightning protection product designed for the solar photovoltaic system based on the relevant standards. It is an electronic device that provides safety protection for photovoltaic devices, mainly for limiting overvoltage and discharging current. Surge protector is usually connected with protected equipment. When overvoltage is generated, it can play the role of shunting and voltage limiting. Prevent excessive current and voltage from damaging the equipment.

Product features

1. equipped with solar photovoltaic DC high voltage lightning arrester, positive and negative electrodes have dual lightning protection function.

2. it has the indication of working status, which is convenient for observing work condition.

3. leakage intelligent recognition

4. Beautiful appearance, fine work

Product specification

Working principle of product

In the solar photovoltaic 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, which will cause serious consequences for the operation of the photovoltaic system. The photovoltaic lightning arrester is specially developed for this purpose. The lightning protection module of the DC power supply, once the high voltage, and endanger the insulation of the protected equipment, the lightning arrester acts immediately, and the high voltage impact current is directed to the earth, thus limiting the amplitude of the voltage and 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.

Use of attention

1. when installing, pay attention to the cable entering and leaving the surge protector. The cables should be separated to avoid the two coupling of surge.

2. identify the input / output interface identifier of the lightning protector, input the external line and output the connection device.

3. grounding lines should be short, thick and straight, so as to reduce the influence of distributed inductors on the ability of lightning electromagnetic pulse.

4. connect the grounding wire of the lightning protector with the ground wire of the lightning protection system.
