Surge protection device for power supply system , lightning protection system
Working principle of product
When the surge protector has no voltage, the impedance
is very high, which means that the circuit breaker is open. When
the voltage occurs, the impedance drops to a few Europe, and the
surge current will flow through the surge protector and will not
enter the device. At the same time, because the surge protector has
a small impedance at this time, the voltage on both sides of the
surge is relatively small, and because he is in parallel with the
protected equipment, it prevents the equipment from suffering from
large surge power. Pressure, so as to play the effect of discharge
and pressure limiting.
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.
Product features
1. advanced production process and beautiful appearance
2. the product has many interfaces and is easy to use.
It doesn't need to worry about the number of interfaces.
3. self protection voltage is more than self
protection, automatic disconnection and recovery.
4. adopt the latest arc extinguishing technology to
avoid fire.

product description
The power supply surge protector, also known as the
power supply lightning protection device, is suitable for the AC
50/60HZ, the rated voltage 220V/380V power supply system, the
indirect lightning and direct lightning impact or other
instantaneous overvoltage surge protection, suitable for home
housing, the third industry and industrial field surge protection
requirements, with relative phase, relative. The relative middle
line, the middle line to the ground and its combination protection
mode.
Use of attention
1. when the current carrying conductor is part of the
closed loop, the circuit and the induced voltage decrease as the
conductor approaches the circuit.
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. data line: more than 2.5mm2; when the length of more than
0.5 meters of more than 4mm2.
