Description

Technical Field

[0001] This invention belongs to the technical field of pressure testing devices, specifically relating to a closing pressure testing device for the spring mechanism of a GIS circuit breaker. Background Technology

[0002] GIS circuit breakers are core components of gas-insulated, metal-enclosed switchgear, used to control and protect power systems. Their core function is to carry and interrupt load current during normal power system operation, and to quickly interrupt abnormal current in the event of short circuits or other faults, protecting equipment safety. GIS circuit breakers use SF6 gas as the insulating and arc-extinguishing medium, possessing high insulation strength, strong arc-extinguishing capability, and high reliability, and are widely used in medium and high voltage power systems. A GIS circuit breaker mainly consists of an arc-extinguishing chamber, operating mechanism, transmission system, support structure, and sealing structure. The arc-extinguishing chamber is its core component, including moving contacts, stationary contacts, nozzles, and a compression cylinder. Utilizing the thermal expansion and compression of SF6 gas, a high-pressure airflow is formed during opening, rapidly extinguishing the arc. The operating mechanism drives the circuit breaker to perform opening and closing operations, including spring mechanisms, hydraulic mechanisms, and hydraulic-spring mechanisms. Among these, the spring mechanism is widely used due to its simple structure and high reliability.

[0003] The invention patent with application number CN202411721601.1 discloses a closing pressure testing device for the spring mechanism of a GIS circuit breaker, including a lower plate and a pressure sensor. Side plates are symmetrically fixedly connected to the top of the lower plate, and the top ends of the two side plates are fixedly connected to the same top plate. The device also includes: a hydraulic rod fixedly installed in the middle of the interior of the top plate; a compression plate fixedly installed at the bottom end of the telescopic part of the hydraulic rod; a base plate fixedly connected to the middle of the top of the lower plate; a limiting mechanism is provided on the inner sides of the two side plates; and a moving mechanism is provided inside the base plate. The limiting mechanism includes a fixing sleeve installed on the outer side of one of the telescopic parts, and a bolt is threaded into the fixing sleeve. This invention solves the problem that during subsequent pressure testing of the spring, it is inconvenient to provide auxiliary guidance for the spring under test, which may cause the spring to tilt and contract, hindering the pressure testing process and affecting the test results. However, it has poor adaptability to springs of different sizes and requires a large amount of manual operation by staff, resulting in poor efficiency in pressure testing.

[0004] Spring mechanisms are commonly used operating mechanisms in GIS circuit breakers. Their working principle is based on the energy storage and release of springs. To ensure their long-term stable and reliable operation, it is necessary to conduct closing pressure tests on their spring mechanisms. Therefore, it is essential to provide a closing pressure testing device for the spring mechanisms of GIS circuit breakers. Summary of the Invention
