Abstract

The invention discloses a switchgear remote intelligent test method, comprising a step of establishing a switchgear intelligent test hardware platform; a step of establishing a switchgear remote intelligent test software platform; a step of selecting a communication channel address; a test step of a switch characteristic test unit; and a test step of a loop resistance test unit. The beneficial effects are that through the hardware platform, the method can measure a plurality of parameters of a breaker and artificially and intelligently control test; test units can work independently, and do not influence work test; the method can modularize and intelligentize a lot of tedious test work such as breaker mechanical characteristic test, breaker switching-closing low voltage test, and breaker switching-closing loop test, and perform communication through a wireless network; test personnel can transmit test data to associated equipment or personnel any time any where; the method can be used in equipment emergency repair work, and report fault equipment statuses to superior leaders the first time so as to rapidly and effectively eliminate faults.

Description

Technical field

[0001] The invention belongs to the technical field of power equipment maintenance and repair, and relates to a remote intelligent testing method for switch equipment. Background technique

[0002] It is often necessary to test the circuit breakers and isolating switches in the substation at the work site of the primary overhaul team. There are many types of test items. Daily maintenance and pre-testing, commissioning of new equipment, and elimination of faults all require testing of primary equipment in the substation. Circuit breakers and isolating switches are the most numerous equipment in substations, and they are also the core equipment related to the safe and stable operation of the power grid. The test data of these two equipment is an important basis for the normal operation of the equipment. For circuit breaker and isolating switch related tests, you need to carry 3-4 test instruments and 2-3 other accessory boxes. Problems such as leaking straps an...
