Abstract

The invention discloses an insulation performance rapid one-key test system and method.The insulation performance rapid one-key test system comprises a channel switching module, a discharge control module, a measurement discharge switching module, a high-voltage excitation module and an acquisition input module. The channel switching module comprises five channel switching circuits A, B, C, N and G. The channel switching circuit A comprises a relay K2 and a relay K3; and the channel switching circuit B comprises a relay K4 and a relay K5. According to the invention, the three-phase end part of the tested equipment is led to the test instrument body through the test wire, the instrument carries out the switching of internal wiring through the change-over switch, meanwhile, the insulation performance of the distribution network equipment is detected by using an intelligent terminal (a mobile phone and the like) remotely, manual on-site operation of personnel is not needed, and the insulation performance detection of the equipment can be really converted from''shaking detection'' to ''telemetering'' and from''repeated manual detection'' to ''one-key automatic detection''.

Description

technical field [0001] The invention relates to the technical field of electrical testing, in particular to a fast one-key testing system and method for insulation performance. Background technique [0002] In the power industry, digital megohmmeters are mainly used to measure the insulation resistance of electrical equipment such as generators, transformers, transformers, motors, power cables, and lightning arresters. The insulation resistance test can sensitively reflect the insulation of the tested equipment and can Effectively find partial or overall moisture and dirt on equipment, as well as defects such as insulation damage and severe overheating and aging. At present, when measuring the insulation value of each circuit of the distribution network equipment (such as the three-phase insulation value test items of the busbar include A-BCE, B-ACE, C-ABE), during the test process, after the end of each phase insulation resistance test, It is necessary to fully discharge t...
