Abstract

The present invention discloses a dry-type hollow reactor turn-to-turn test device performance checking system and method. The system comprises a sectional type dry-type hollow reactor, a turn-to-turn short circuit simulation unit, a turn-to-turn insulation defect simulation unit and an operation state monitoring unit. The sectional type dry-type hollow reactor, the turn-to-turn short circuit simulation unit, the turn-to-turn insulation defect simulation unit and the operation state monitoring unit are connected in order. According to the designed simulation turn-to-turn insulation defect dry-type hollow reactor, the types and the positions of the dry-type reactor simulation defects are regulated to allow the dry-type reactor to present different defect states and check the effectiveness of the dry-type hollow reactor turn-to-turn insulation test device system. The dry-type hollow reactor turn-to-turn test device performance checking system and method employ a special dry-type hollow reactor with known defect positions and controllable types of defects to allow the functions of the dry-type reactor turn-to-turn insulation test device system to be verified and compared so as to effectively ensure the effectiveness and the applicability of the dry-type hollow reactor turn-to-turn insulation test device.

Description

technical field [0001] The invention relates to the technical field of reactor insulation tests, in particular to a performance check system and method for a dry-type air-core reactor turn-to-turn insulation test device. Background technique [0002] With the large-scale application of dry-type air-core reactors in power grids, accidents caused by various defects of reactors will inevitably occur. In the statistics of reactor defects, it is found that short-circuit faults caused by inter-turn insulation occur in various Defects accounted for the highest proportion, close to half. Most of the reactor faults are caused by inter-turn short circuit, which causes the reactor to ignite and burn, which has a great impact on the safe and stable operation of the power system. [0003] Aiming at the research on the detection and testing device of inter-turn insulation of dry-type air-core reactor (hereinafter referred to as inter-turn insulation), a variety of test techniques and met...
