Description

Technical Field

[0001] The present invention relates to a card slot type battery connection clip for a substation and a usage method thereof, belonging to the technical field of auxiliary tools for battery replacement. Background Art

[0002] In a substation, the DC system, as a key infrastructure, shoulders the important responsibility of providing reliable power for key loads such as relay protection devices, safety automatic devices, control circuits, and emergency lighting. Among them, the battery pack, as the core energy storage unit of the DC system, constitutes the ultimate barrier for the safety redundancy guarantee of the station power supply. It should be noted that under the continuous floating charge working condition, the battery monomers are prone to deterioration phenomena such as capacity attenuation or abnormal increase in impedance during the annual full-capacity capacity verification test and internal resistance test. At this time, it is necessary to quickly locate and replace the deteriorated monomers to maintain the overall reliability of the system.

[0003] When replacing a faulty battery in a live working environment, a bridging instrument needs to be used to establish a physical connection with the faulty battery. However, there are the following technical difficulties in actual operation: the surface of the battery connection bolt is smooth and the gap with the top of the housing is narrow. When using a traditional alligator clip type wiring device, due to the insecure clamping structure of the clamping structure, affected by external factors such as the self-weight traction of the cable or the accidental touch of the operator's body, it is very easy to occur displacement detachment of the contact terminal and difficult installation. Such unplanned contact interruption will directly lead to an open circuit in the test circuit, which may cause electrical safety risks such as system voltage transient or arc discharge. Summary of the Invention

[0004] The purpose of the present invention is to provide a card slot type battery connection clip for a substation and a usage method thereof, which can solve the problems caused by the smooth surface of the bolt, narrow wiring space, and uncertain factors in on-site operation when replacing a faulty battery live.
