Transformer turn-to-turn short circuit online monitoring system and method based on electric energy loss

Abstract

The invention provides a transformer turn-to-turn short circuit online monitoring system and method based on electric energy loss. The power loss can be monitored through a data operation judgment module; and a contact fault of the joint of a transformer bushing can be diagnosed through an infrared diagnosis module, so that a turn-to-turn short circuit fault of a transformer can be further monitored from multiple aspects. Therefore, the transformer turn-to-turn short circuit online monitoring system based on the electric energy loss can be used for monitoring the turn-to-turn short circuit fault of the transformer efficiently, and the data operation judgment module and the infrared diagnosis module can be used for carrying out detection from multiple aspects, so that the fault can be foundin time in an early stage of the fault; and a fault signal is uploaded to a control center, so that an operation accident can be avoided, the actual service life of the transformer is prolonged, thepower supply reliability is improved, and the convenience and accuracy of detecting the turn-to-turn short circuit fault of the transformer are improved.

Description

technical field [0001] The present application relates to fault diagnosis of distribution transformers, in particular to an on-line monitoring system and method for transformer interturn short circuit based on power loss. Background technique [0002] The distribution transformer is a high-voltage electrical equipment that realizes the conversion of different voltage levels of electric energy in the power system. It undertakes the task of converting voltage and current and transmitting electric power. Therefore, the performance of the distribution transformer will directly affect the safe and stable operation of the power system. At the same time, its normal operation is the key to the normal operation of the entire distribution network system. After a turn-to-turn short-circuit fault occurs in a distribution transformer, the faulty winding will generate a large short-circuit current, and various losses such as heat generation will increase, which in turn will destroy the in...
