The first stage power supply lightning protector three phase
lightning protection
Product Details
Surge protector is the lightning protection measures taken by
Zhejiang toer Electric Co., Ltd. for the electrical system. It
provides electronic equipment for all kinds of electronic
equipment, instruments and communication lines. When overvoltage is
generated, the effect of shunting and voltage limiting can be
achieved. To prevent excessive current and voltage damage to
equipment, play the role of protection devices.
Use of attention
1. in order to limit the inductive coupling between the protected
part after installation and the part of the unprotected equipment,
we need to make some measurements. The mutual inductance can be
reduced by the separation of the inductive source and the
sacrificial circuit, the selection of the loop angle and the
limitation of the closed loop area.
2. identify the input / output interface identifier of the
lightning protector, input the external line and output the
connection device.
3. it should match the working voltage of the protected equipment.
Please install according to the installation sketch.
Product features
1. multi-functional overvoltage protection, lightning and
overpressure are no longer afraid of disasters.
2. self protection voltage is more than self protection, automatic
disconnection and recovery.
3. safety insulation of fire retardant and high flame retardant
material
Product Installation
With 35mm standard DIN-rail mounting, connecting copper stranded
conductor is 2.5~35mm²
At front of spd each pole must be setted protection---used fuse or
miniature circuit breaker lightning current SPD protection,after
SPD breakdown to short circuit protection.
SPD install on protected line(equipment) to the front and connected
to the supply line. A class products install in the building
home-entry line hold larger surge current total distribution box.
B, C class products most install on the floor distribution box, D
class products close to the front-end equipment that smaller surge
current, smaller residual voltage place.

Working principle of product
In the equipment system, the inductive or capacitive coupling
voltage is caused by the lightning shock and the switching
operation of the upstream power supply system. Therefore, the surge
may damage the photovoltaic modules and inverters and other
devices. This will cause serious consequences for the operation of
the system. The surge protector is a DC power defense specially
designed for this purpose. The lightning module, once the high
voltage, and endanger the insulation of the protected equipment,
the lightning arrester acts immediately, the high voltage impact
current guide the earth, thus limiting the voltage amplitude,
protecting the insulation of the equipment. When the overvoltage is
gone, the arrester is restored to its original state quickly, so as
to protect the power equipment.
