Problems solved by technology

This method has higher requirements for the testers. The pressure gauge adopts a mechanical meter, and the tester’s readings have errors, and the two readings cannot be guaranteed to be observed at the same position; the reading must be taken immediately after the switch is opened or closed, otherwise the pressure will be damaged. There is a drop or rise that affects the readings, and the accuracy rate is low; after the work is completed, it is necessary to manually fill in the form and calculate it. Compared with the standard value, the test efficiency is relatively low

Description

technical field [0001] The invention relates to the technical field of high-voltage circuit breaker detection, in particular to a device and method for detecting pressure drop data of a circuit breaker with a hydraulic operating mechanism. Background technique [0002] In order to ensure that the circuit breaker operated by the hydraulic mechanism can open and close the circuit breaker correctly many times when the energy storage power supply is disconnected, the energy loss generated during the opening process of the circuit breaker and the energy loss generated during the closing process must be carefully considered. Measurement, in specific work, can be judged by measuring the pressure difference of the energy storage medium before and after opening and the pressure difference before and after closing, that is, the opening pressure drop and closing pressure drop. At present, it is mainly through manual judgment. Testers record the value of the pressure gauge before the s...
