Brief introduction

Surge protector is the lightning protection measures taken by Zhejiang toer Electric Co., Ltd. for the electrical system. It mainly plays the role of protecting the line from lightning protection and overvoltage protection. Circuit protection is made up of a powerful diode solid state discharge tube; basic and fine protection is based on an automatic fault protection device. During thermal overload, the device moves the two ends of the original lightning protection together, thus causing the damage caused by the surge.

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.

Product features

1. low output residual pressure to further ensure safety

2. core components are strictly screened, stable performance and reliable operation.

3. built-in overheating and temperature control circuit breaker

Product specification

Structure and Principle

SPD is a port, shocking protection, indoor-mounted installation, voltage-limited.

SPD hold disconnector inside, when SPD breakdown failure by over heating, the disconnector can remove from the power grid automatically, and show indication signal. When SPD is working properly, visible window display green, it display red when it breakdown and disconnect.

1P+N,2P+N,3P+N SPD consist of 1P,2P,3P SPD+NPE zero ground protection module, apply to TN-S, TN-C-S and other power supply system.

Use of attention

1. it should match the working voltage of the protected equipment. Please install according to the installation sketch.

2. lightning protector should be regularly tested during operation. If there is any failure, it should be maintained or replaced in time to ensure equipment safety.

3. 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.
