Reliable DC Surge Protective Devices serve as the silent guardians of DC system safety. We are dedicated to manufacturing these critical protective devices, providing robust surge protection for your solar power plants, energy storage systems, and industrial control cabinets. This ensures stable system operation, safeguarding your core investments and operational security.

Solar Power Electrical Devices Function Introduction

DC circuit breaker mainly has the following functions:

Function	Description
Interrupt Direct Current	Designed to safely interrupt direct current (DC) flow in electrical circuits to protect against overloads and short circuits.
Arc Suppression	Utilizes various mechanisms such as magnetic fields and auxiliary capacitors to suppress arcs generated during the breaking process.
Bidirectional Fault Current Interruption	Capable of interrupting fault currents in both directions, ensuring comprehensive protection in DC transmission lines.
Magnetic Field Application	Applies a magnetic field to the vicinity of the arc to control and extinguish it quickly, enhancing performance.
Simplified Structure	Incorporates filtering and surge-absorbing capacitors to simplify the overall structure and improve efficiency.
Self-Excited Commutation	Uses self-excited commutation techniques to enhance the speed and reliability of current interruption.

DC Surge Protective Devices (SPD) are designed to protect DC systems from transient overvoltage and lightning surges. They provide fast response and reliable discharge of surge energy to protect sensitive equipment. Inquire

Features of Surge protective devices DC

(1). The connecting wire should be used with the same capacity as the power line or greater than the power line, the total length should be controlled within 0.5 meters, The shorter the wire length, the better. (2). There must be corresponding air switches or fuses in series at the front end of the surge protector. (3). The power supply must be disconnected during the installation. (4). Fault judgment of the surge protector: ① The indicator window of the module is green (normal). When the module deteriorates, the indicator window should be replaced in time; ② Surge protector can be equipped with (FS) remote remote communication alarm, remote communication touch There is a constant open and one constant close, one module or multiple modules of the surge protector failure, the contact will close, send a fault alarm signal, indicating that the module failure must be replaced. ③ Always check the air switches or fuses connected in series on the line.
