Product introduction
Surge protector is the lightning protection measures adopted by Zhejiang toer Electric Co., Ltd. for the electrical system. It is widely used in home, third industry and industrial fields to protect sensitive lines and protect the surge of lightning and direct lightning or other instantaneous overvoltage.
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
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 be supplied 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.
Product features
1. core components are strictly screened, stable performance and reliable operation.
2. using the latest arc extinguishing technology to avoid fire completely
3. module is designed and installed conveniently and can be replaced directly.
