Low-voltage House Protective Arrester Structure and Principle:
SPD is a port, shocking protection, and indoor-mounted installation, voltage-limited. SPD hold disconnector inside, when SPD breakdown failure by overheating, the disconnector can remove from the power grid automatically, and show indication signal. It display red when it breakdown and disconnect. 3P+NPE SPD consist of 3P SPD+NPE zero ground protection module, apply to TN-S, TT and other power supply system.
Low-voltage House Protective Arrester 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.
Low-voltage House Protective Arrester 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.
Notice of product:
1. Grounding lines should be short, thick and straight, so as to reduce the influence of distributed inductors on the ability of lightning electromagnetic pulse.
2. It should match the working voltage of the protected equipment. Please install according to the installation sketch.
