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

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.
Company profile
