State test method of GIS equipment routine power failure cancelling experiment

Abstract

The invention provides a state test method of a GIS equipment routine power failure cancelling experiment. The method comprises the following processes that 1, a non-power-failure routine experiment is carried out according to the period requirement, and if an experiment result passes testing, the equipment state can be accurately grasped, and a corresponding maintenance strategy is directly formulated; 2, if the equipment state needs to be further analyzed, a non-power-failure diagnostic test is carried out pertinently according to the non-power-failure routine experiment and diagnostic test comprehensive evaluation result; 3, a corresponding maintenance strategy is formulated according to the non-power-failure routine experiment and diagnostic test comprehensive evaluation result. GIS equipment is subjected to electricity detection through multiple non-power-failure test items, the advantages of being comprehensive in acquired equipment state information amount, effectively covering main defects and faults and the like are achieved, many problems existing in existing polling and routine experience items are avoided, the GIS equipment operating state can be grasped accurately and conveniently in real time without power failure, the corresponding maintenance strategy is formulated, and safe and reliable operation of the equipment is guaranteed.

Description

Technical field [0001] The invention relates to the technical field of electrical equipment state detection, in particular to a state test method for GIS equipment to cancel routine power outage tests. Background technique [0002] In recent years, power grid companies have begun to implement a state maintenance model, based on equipment state evaluation, strengthen equipment state detection, scientifically formulate maintenance plans, and shift the focus of maintenance work from equipment power outage maintenance to equipment state detection, analysis, evaluation, and pre-control. The over-repair and disrepair of the equipment are greatly reduced, the workload of overhaul is obviously reduced, the cost of overhaul and test of the equipment is reduced, and the reliability of the equipment is obviously improved. However, due to technical limitations, there is still a power outage routine test cycle for condition maintenance. [0003] With the continuous development of electricity d...

Problems solved by technology

[0005] At present, GIS equipment inspection and routine test items include: appearance inspection, gas density value inspection, operating mechanism status inspection, infrared thermal image detection, component test, etc. The amount of equipment status information they obtain is limited and the information lags behind. Some test items It needs power outage to start, which affects the reliability of power supply, and it is difficult to meet the requirements of state evaluation and state control

[0006] In the case of no power supply, the existing routine test items (infrared thermal image detection, SF6 gas humidity detection, ultra-high frequency partial discharge detection, ultrasonic partial discharge detection) can only find heating defects, SF6 gas moisture content exceeds The types of hidden dangers such as class defects cannot be found, and other types of hidden dangers such as mechanical defects cannot be found, and the test items are relatively single, which is far from being able to effectively cover the main defects and faults of GIS equipment, and it is difficult to fully grasp the operation status of GIS equipment
