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.
Product features
1. troubleshooting, automatic closing
2. create the wiring connection to prevent incorrect
contacts, and add a guarantee to your safety.
3. adopt the latest arc extinguishing technology to
avoid fire.
4. with the power status indication, it indicates the
working state of surge protector.

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.
Company profile
