Type 1 surge protection device for higher voltage rating devices
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.
Product features
1. leakage current is small, the response time is fast, and the
residual pressure is low
2. use the pluggable module set up, the maintenance is simple
3. self protection voltage is more than self protection, automatic
disconnection and recovery.

Product Details
Surge protector is a lightning protection measure adopted by
Zhejiang toer Electric Co., Ltd., which is independently developed
and produced for electrical system. Its core components are
composed of multistage graphite gap. Reasonable design and precise
processing of spark and twisting together form a sealing mechanism
to ensure the safety distance of spark gap, even in surge current.
When it passes through, there will be no arc leakage. It will
effectively protect the device against surge and over voltage.
Use of attention
1. 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.
2. grounding lines should be short, thick and straight, so as to
reduce the influence of distributed
inductors on the ability of lightning electromagnetic pulse.
3. 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
