Household solar PV lamp protector anti short-circuit resettable current limiting lightning protection switch

Product introduction

Photovoltaic DC surge protector is a lightning protection product designed for the solar photovoltaic system based on the relevant standards. It is designed and manufactured on the basis of IEC and GB standards, while meeting IEEE802.3AT requirements. The product is standard 35mm guide rail installation, easy installation, single module can be inserted and replaced. According to the different DC power supply, various corresponding specifications can be selected and can be applied to multichannel DC power supply system through a variety of combinations. In terms of material, we choose the brand components and make use of advanced production technology. It has large flow capacity, low residual pressure level, sensitive reaction, stable performance and reliable work. And so on.

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. determine the discharge current path

2. the wire that marks the extra voltage drop caused by the device terminal

.
3. in order to avoid unnecessary induction loops, we should mark the PE conductor of each device.

4. the equipotential connection is established between the 4 and the other.
