lightning arrester , high voltage cabinet lightning protection

Brief introduction

The surge protector is a lightning protection measure adopted by Zhejiang toer Electric Co., Ltd. for the electrical system. It is an electronic device for all kinds of electronic equipment, instruments and communication lines. When a sharp peak current or voltage is produced in an electrical circuit or a communication line because of a sudden external disturbance, the surge protector can guide the shunt in a very short time to avoid damage to the other equipment in the circuit.

Product features

1. limit the precision of the voltage to say how much!

2. using the latest arc extinguishing technology to avoid fire completely

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.

Working principle of product

During the operation of the equipment, the lightning arrester will play a protective role once the abnormal voltage occurs. When the protected device is running under normal working voltage, the arrester will not work, and it will be regarded as a circuit for the ground. Once the high voltage is present and the insulation of the protected equipment is endangered, the lightning arrester acts immediately and leads the high voltage impact current to the earth, thus limiting the amplitude of the voltage and protecting the insulation of the electrical equipment. When the overvoltage is gone, the arrester is restored to its original state quickly, so that the system can supply electricity normally. The main function of the arrester is to reduce the voltage value of the protected equipment by the action of parallel discharge gap or nonlinear resistance, so as to protect the power equipment.

Use of attention

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

2. Connect the grounding wire of the lightning protector to the ground wire of the lightning protection system.

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