Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a reclosing circuit breaker. Background Art

[0002] When the overhead line fault is cleared, closing the circuit breaker in a short time is called reclosing. Since most overhead line faults are actually instantaneous or temporary, reclosing is one of the self-restoring power supply methods commonly used in operation, and reclosing circuit breakers are indispensable accessories in the power grid.

[0003] When in use, the reclosing circuit breakers on the market are generally fixed in a control box, which is inconvenient to install or disassemble. Moreover, when multiple reclosing small circuit breakers are placed side by side, it is not convenient to control them at the same horizontal height. For example, the Chinese utility model disclosure specification is the patent CN219180442U, which discloses a reclosing small circuit breaker. When in use, a fixing plate of corresponding length is selected according to the number of reclosing small circuit breakers, and the four top corners of the fixing plate are installed in the box body or the power box through mounting bolts. Then, multiple circuit breaker bodies are installed on the fixing plate in sequence. During installation, the mounting slide of the circuit breaker body is slidably matched with the slide groove on the fixing plate. After installation, the two ends of the circuit breaker body are limited and fixed at both ends by the matching of the latch rod and the limit socket at both ends of the fixing plate to prevent slipping.

[0004] Existing reclosing circuit breakers do not have a good function of convenient disassembly. For example, the above-mentioned patent can realize the horizontal installation of the reclosing circuit breaker and the disassembly of the reclosing circuit breaker. However, in actual use, when disassembling the reclosing circuit breaker, it is necessary to disassemble it from the outside to the inside. If the reclosing circuit breaker close to the inside is damaged or needs maintenance, it is necessary to disassemble the multiple reclosing circuit breakers on the outside first. Disassembly has certain limitations and is inconvenient to use. Utility Model Content
