Description

technical field [0001] The invention mainly relates to the field of on-line detection of electrical equipment, in particular to a laboratory simulation test method and device for an on-line detection device of electrical equipment, which is suitable for a laboratory verification test of the performance of the on-line detection device of electrical equipment. Background technique [0002] The electrical equipment on-line detection device mainly detects the main performance indicators of electrical equipment through online methods, such as online detection of discharge faults, overheating faults and mechanical faults of electrical equipment. Such as: on-line detection of partial discharge, on-line leakage current detection, on-line detection of dielectric loss tangent, on-line detection of local overheating and on-line audio detection of electrical equipment, etc. These on-line detection devices are mainly to predict possible faults during the operation of electrical equipment ...

AI Technical Summary

Problems solved by technology

However, due to the lack of industry standards and factory test standards for the current online detection methods for electrical equipment, some functional indicators cannot be tested, and the probability of failure of electrical equipment on site is low, it is difficult for the online detection device to capture the failure of the electrical equipment under test during operation , the function and accuracy of its online detection method and device cannot be verified

Since the performance of the on-line detection method and device cannot be verified when leaving the factory, this also raises doubts for users whether the on-line detection device of electrical equipment meets its performance indicators, so it is urgent to develop a laboratory simulation test method for the on-line detection device of electrical equipment It is used to verify the correctness, sensitivity and accuracy of the online detection device of electrical equipment, and solve the research test and factory test of the current online detection device of electrical equipment
