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.

Product specification

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.
