product description
Surge protector is the lightning protection measures taken by
Zhejiang toer Electric Co., Ltd. for the electrical system, which
provides safety protection for all kinds of electronic equipment,
instruments and communication lines. It is mainly used to limit
overvoltage and discharge electric current. Surge protector is
usually connected with protected equipment. When overvoltage is
generated, it can play the role of shunting and voltage limiting.
To prevent excessive current and voltage damage to equipment, play
the role of protection devices.
Product features
1. self protection voltage is more than self
protection, automatic disconnection and recovery
.
2. module is designed and installed conveniently and can be
replaced directly.
3. the speed of response is 0.001 seconds, and
the voltage is controlled in the range that the equipment can
withstand.

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
Working principle of product
Power surge protector is divided into two parts: explosion proof
box type and modular type. A varistor with excellent nonlinear
characteristics is adopted. Under normal conditions, the surge
protector is in extremely high resistance state, and the leakage
current is almost zero, thus ensuring the normal power supply of
the power supply system. When the power system surge overvoltage,
the power surge protector immediately passes in the nanosecond
time, limits the amplitude of the overvoltage to the safe working
range of the equipment, and releases the surge energy into the
ground. Subsequently, surge protector rapidly changes to high
resistance state, so that normal power supply is not affected.
Use of attention
1. lightning protection device IN as input and OUT as
output, the input end is connected with the outside, and the output
end of the input end of the connecting device is protected.
2. 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.
3. after correct installation, it can work steadily for a
long time. If it is found that the transmission performance of the
system is reduced or the signal is interrupted due to the cause of
surge protection, it should be maintained or replaced in time.
