Working principle of product
The lightning arrester can effectively protect the power equipment. Once the abnormal voltage appears, the lightning arrester will play a protective role. 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 lightning arrester is to reduce the voltage value of the protected equipment through the action of parallel discharge gap or nonlinear resistance, and to reduce the voltage value of the protected equipment, so as to protect the power equipment.

Product features
1. module is designed and installed conveniently and can be replaced directly.
2. use the pluggable module set up, the maintenance is simple
3. use temperature control protection circuit, built-in thermal protection
Notice of product
1. generally speaking, it is better to separate the protected conductor from the non protected conductor, and it should be separated from the ground wire. At the same time, in order to avoid transient orthogonal coupling between power cables and communication cables, necessary measurements should be made.
2. the protected equipment must have good grounding, and the grounding impedance value is according to the relevant standard.
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.
Product introduction
Surge protector is the lightning protection measures taken by Zhejiang toer Electric Co., Ltd. for the electrical system. It is used to prevent lightning from the circuit system, and it is an important manifestation of internal lightning protection.
It is suitable for household, third industry and industrial equipment to avoid overvoltage damage caused by system induced lightning and electrostatic discharge. The grounding point is treated by special process to avoid signal interference. The multi-stage protection circuit has many advantages, such as small insertion loss, fast response speed, accurate clamping and low output voltage.
