Megohmmeter Simulation Verification Method

Abstract

The invention discloses a simulation calibration method for megameters. The simulation calibration method includes the steps of a, building a virtual test scene and initializing the same, b, building a virtual megameter, a virtual high-voltage high-resistance cabinet and / or a virtual high-voltage digital voltmeter in the virtual test scene, c, performing calibration connection to the virtual megameter, the virtual high-voltage high-resistance cabinet and / or the virtual high-voltage digital voltmeter, d, building a measured value normal state table and a measured value abnormal state table of the virtual megameter, e, triggering functional modules on the virtual megameter, the virtual high-voltage high-resistance cabinet and / or the virtual high-voltage digital voltmeter which are built in the step b, and starting to calibrate the virtual megameter and displaying the acquired calibration data. By the simulation calibration method, huge capital investment is avoided; by means of simulation testing, damages to instruments due to errors in operations are avoided, and risks in test are reduced.

Description

technical field [0001] The invention relates to the technical field of megohmmeter verification, in particular to a megohmmeter simulation verification method. Background technique [0002] High-voltage equipment is very critical equipment in power systems and large-scale user substations. The insulation performance of high-voltage equipment determines whether it is safe to use high-voltage equipment. The insulation performance is reflected by the insulation resistance. The insulation resistance is usually measured by a megohmmeter. The field test of the equipment, the preventive test in operation, the handover test and the accident diagnosis all need to use the megohmmeter for verification. Generally, the megohmmeter is required for the insulation performance test of the high-voltage equipment and the training of relevant personnel. The megohmmeter is very precise, it is easy to be damaged by improper operation, and the price is very high. Enterprises need a lot of money to...

[0002] High-voltage equipment is very critical equipment in power systems and large-scale user substations. The insulation performance of high-voltage equipment determines whether it is safe to use high-voltage equipment. The insulation performance is reflected by the insulation resistance. The insulation resistance is usually measured by a megohmmeter. The field test of the equipment, the preventive test in operation, the handover test and the accident diagnosis all need to use the megohmmeter for verification. Generally, the megohmmeter is required for the insulation performance test of the high-voltage equipment and the training of relevant personnel. The megohmmeter is very precise, it is easy to be damaged by improper operation, and the price is very high. Enterprises need a lot of money to purchase the megohmmeter. Moreover, when performing verification and calibration, it needs to be carried out in a very demanding experimental environment, and a standard laboratory should be established. The investment is very large, and after the data is detected, if there is abnormal data, it is difficult to get the reason for the abnormality, so it is difficult to calibrate or optimize the design of the equipment through monitoring data
