Automatic high-voltage circuit breaker detection system

Abstract

The invention discloses an automatic high-voltage circuit breaker detection system and relates to the technical field of detection for power equipment in a power system. The automatic high-voltage circuit breaker detection system comprises a circuit breaker pre-testing item detection unit, a PLC (Programmable Logic Controller) logic processing unit and an upper computer processing unit which are connected in sequence. Property indexes such as the mechanical property, the loop resistance, the insulation resistance and the medium consumption of a circuit breaker are respectively detected by a mechanical property detection unit, a loop resistance detection unit, an insulation resistance detection unit and a medium consumption detection unit of the circuit breaker pre-testing item detection unit, all detection data are uniformly converted and classified through the PLC logic processing unit and are further processed and analyzed by the upper computer processing unit, then detection resultsand primary diagnosis conclusions can be made, the defect that a plurality of detectors need to be carried over for multiple detection items is avoided, a high-voltage circuit breaker can be detectedrelatively intelligently and integrally, the production and management efficiency is greatly improved, the labor and the materials are saved, and the working intensity is alleviated.

Description

technical field [0001] The invention belongs to the technical field of detection of power equipment in a power system, and in particular relates to an automatic detection system for a high-voltage circuit breaker. Background technique [0002] At present, as the requirements for the preventive test procedures of power companies are getting higher and higher, and the requirements for various countermeasure documents are becoming more and more stringent, there are many problems encountered in the test of circuit breakers, especially for 500kV circuit breakers: firstly, there are many testing items, When carrying out the test, it is necessary to carry a variety of instruments, frequently carry, replace the instrument, change the test lead, connect and disconnect, use different testing instruments and software, the labor intensity is high, and the requirements for the test personnel are high; secondly, the test results of each item are manually managed , need to spend a lot of p...
