Automatic high-voltage circuit breaker detection device and detection method

Abstract

The invention discloses an automatic high-voltage circuit breaker detection device and a detection method and relates to the technical field of power equipment in a power system. The automatic high-voltage circuit breaker detection device comprises a PC (Personal Computer), a system host computer and an intelligent wiring unit. By adopting the device, detection functions such as mechanical properties, loop resistance, insulation resistance, medium consumption and capacitance of a high-voltage circuit breaker are integrated, automatic switching of wiring states of the intelligent wiring unit isautomatically controlled through control instructions of the PC, detection on all detection items is completed automatically after one time of wiring, the working intensity of testers is alleviated,requirements for the testers are reduced, the working efficiency of detection is improved, meanwhile the power-off time is shortened, the security risks of detection testing are reduced, and the high-voltage circuit breaker is relatively reliably detected; and the detection device disclosed by the invention is high in integration, small in size and weight, simple and reliable to operate and applicable to testing and analysis on ultra-high voltage circuit breaker.

Description

technical field [0001] The invention belongs to the technical field of detection of electric power equipment in a power system, and in particular relates to an automatic detection device and a detection method of a high-voltage circuit breaker. Background technique [0002] The power company substation site, especially the high-voltage circuit breaker of 500kV and above, has a relatively high space position, and the test personnel of the power supply bureau frequently climb up to connect and disconnect the wires, which poses a high safety risk, and factors such as on-site induced electric strength threaten the test personnel and test equipment. Safety issues have increased the risk of operation; secondly, the test process requires a long power outage and low efficiency. It takes at least two working days to complete the pre-test work of a 500kV high-voltage circuit breaker interval equipment. Frequent handling, replacement of instruments, change of test leads, connection and...

[0002] The power company substation site, especially the high-voltage circuit breaker of 500kV and above, has a relatively high space position, and the test personnel of the power supply bureau frequently climb up to connect and disconnect the wires, which poses a high safety risk, and factors such as on-site induced electric strength threaten the test personnel and test equipment. Safety issues increase the risk of operation; secondly, the test process requires a long power outage and low efficiency. It takes at least two working days to complete the pre-test work of a 500kV high-voltage circuit breaker interval equipment

Frequent handling, replacement of instruments, change of test leads, connection and disconnection, and use of different testing instruments and software are labor-intensive and require high requirements for test personnel.
