A three-phase self duplex undervoltage protector for photovoltaic
380V is automatically restored to overpower
Product introduction
Solar surge protector is a kind of surge protector, which is mainly
used for lightning protection measures adopted in photovoltaic
system. It is an important manifestation of internal lightning
protection. According to the characteristics of photovoltaic
system, we use multi-level protection to maximize the voltage into
the underground, so as to achieve the role of lightning protection
and overvoltage.

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. the standard RJ45 interface can be conveniently connected to the
front end of the protected device, and the grounding path should be
as short as possible, and the length should not exceed 1.5 meters.
2. when installing, pay attention to cables coming in and out of
surge protective devices, so as to avo id the two coupling of
surge.
3. the protected equipment must have good grounding, and the
grounding impedance is in accordance with the relevant national
standards.
4. 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.
