Overvoltage and zero interruption photovoltaic arrester, self
duplex undervoltage protector, household lightning protect
Brief introduction
Photovoltaic DC lightning arrester is a lightning protection
measure independently developed by Zhejiang tol Electric Co., Ltd.
for household solar power generation. It is used to protect
sensitive lines, protect the induced lightning and direct lightning
or other transient overvoltage surges. The lightning arrester
adopts the multi-stage protection circuit, selects the brand
components and makes use of the advanced production technology. It
has the characteristics of large flow capacity, low residual
pressure level, sensitive reaction, stable performance, reliable
work and so on. It is suitable for DC surge protection in
photovoltaic generation, wind power generation and other industrial
fields.

Working principle of product
In the solar photovoltaic 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, which will cause
serious consequences for the operation of the photovoltaic system.
The photovoltaic lightning arrester is specially developed for this
purpose. The lightning protection module of the DC power supply,
once the high voltage, and endanger the insulation of the protected
equipment, the lightning arrester acts immediately, and the high
voltage impact current is directed to the earth, thus limiting the
amplitude of the voltage and 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.
Use of attention
1. identify the input / output interface identifier of the
lightning protector, input the external line and output the device.
2. 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.
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.
