A three-phase self duplex undervoltage protector for photovoltaic 380V is automatically restored to overpower

Product introduction

Solar surge protector is a kind of surge protector, which is mainly used for lightning protection measures adopted in photovoltaic system. It is an important manifestation of internal lightning protection. According to the characteristics of photovoltaic system, we use multi-level protection to maximize the voltage into the underground, so as to achieve the role of lightning protection and overvoltage.

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. the standard RJ45 interface can be conveniently connected to the front end of the protected device, and the grounding path should be as short as possible, and the length should not exceed 1.5 meters.

2. when installing, pay attention to cables coming in and out of surge protective devices, so as to avo id the two coupling of surge.

3. the protected equipment must have good grounding, and the grounding impedance is in accordance with the relevant national standards.

4. After correct installation, it can work steadily for a long time. If it is found that the transmission performance of the system is reduced or the signal is interrupted due to the cause of surge protection, it should be maintained or replaced in time.
