Description

Technical Field

[0001] This utility model relates to the field of backup surge protector technology, and more specifically to a dedicated backup integrated surge protector. Background Technology

[0002] Backup surge protectors are mainly used to enhance the safety of surge protection systems. They quickly disconnect the circuit when a surge protector (SPD) fails, preventing fires and damage to electrical equipment. When a surge protector fails due to aging, overload, or short circuit, the backup protector can disconnect the circuit within milliseconds, avoiding fires or equipment damage caused by power frequency leakage current. Working in conjunction with an SPD, they form dual protection, withstanding lightning strikes while preventing permanent damage to the SPD due to overload, thus extending the overall system lifespan.

[0003] Current technology has several shortcomings: Connecting a separate backup surge protector to the SPD increases the wiring length at both ends of the SPD, leading to an increase in the residual voltage of the SPD and directly affecting the safety of the protected equipment. In addition, the large size of the separate backup surge protector and SPD means that they occupy a large space when installed together in a cabinet, which is not conducive to centralized assembly. When using a backup surge protector, it mainly detects the circuit through its internal core and quickly cuts off the power when a lightning strike occurs. The core is susceptible to damage from lightning, while other components are less affected and less prone to damage. Most existing backup surge protectors are integrated structures, and when the core is damaged, the entire unit needs to be discarded and replaced, resulting in a waste of resources.
