Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage circuit breaker testing, in particular to a testing assistant for a high-voltage circuit breaker. Background Art

[0002] The trolley-type high-voltage circuit breaker is a switchgear designed for use in high-voltage power systems. It installs the high-voltage circuit breaker and its related control and protection equipment on a movable trolley (i.e., a trolley). The trolley can be easily moved between different positions along the guide rails in the switch cabinet for easy operation, maintenance, and overhaul. Before using the trolley-type high-voltage circuit breaker, it is necessary to test the voltage and other data on the output part of the head of the trolley-type high-voltage circuit breaker through the connecting joint. During normal testing, the trolley-type high-voltage circuit breaker needs to be pulled out of the cabinet and the test wire clamps are clamped on the six joints respectively.

[0003] However, during testing, the trolley-type high-voltage circuit breaker needs to be separated from the test device in the cabinet for each test. However, due to the different sizes of the internal spaces of the test devices, the user needs to pull the trolley-type high-voltage circuit breaker away from the test device. The user then connects the connector to the head output of the trolley-type high-voltage circuit breaker manually or with the help of external tools. After the connection, it needs to be pushed back into the test cabinet, which is time-consuming and laborious, increases the user's workload, reduces the test efficiency, and is inconvenient to use. Therefore, we propose a test assistant for high-voltage circuit breakers with easy-to-use functions, which needs to be developed urgently. Utility Model Content
