Electrified detection system for nuclear power station oil-immersed transformer

Abstract

The invention belongs to the technical field of nuclear power station power transmission and distribution and protection. The invention provides an electrified detection system for an oil-immersed transformer of a nuclear power station. The system comprises a sleeve voltage-sharing cover vibration measurement module and a nuclear power station oil-immersed transformer. The nuclear power station oil-immersed transformer comprises a shell, a high-voltage sleeve, a sleeve lead and a voltage equalizing cover, and the high-voltage sleeve comprises a sleeve body and a sleeve shell arranged outside the sleeve body in a sleeving mode. A sleeve ascending flanged base is arranged on the shell; the sleeve shell is installed on the sleeve ascending flanged base, one end of the high-voltage sleeve extends into the shell, the other end of the high-voltage sleeve extends out of the shell, the sleeve body at an end, located in the shell, of the high-voltage sleeve is connected with the sleeve lead, and the voltage equalizing cover is fixed to the sleeve body through a bolt and wraps the connection of the sleeve lead and the sleeve body. Through the system provided by the invention, the fault problem of the voltage equalizing cover in the oil-immersed transformer can be efficiently positioned and detected, and the overall detection efficiency of the oil-immersed transformer is further improved.

Description

technical field [0001] The invention belongs to the technical field of power transmission, distribution and protection of nuclear power plants, and more specifically relates to a live detection system for oil-immersed transformers of nuclear power plants. Background technique [0002] At present, in the process of inspection and maintenance of oil-immersed transformers in nuclear power plants, it is necessary to detect whether the bolts of the voltage equalizing cover in the oil-immersed transformer are loose or fall off (the looseness or fall of the bolts will cause phenomenon of corona discharge), in the prior art, to detect whether the bolts of the voltage equalizing cover in the oil-immersed transformer are loose or fall off, firstly, the transformer oil in the oil tank of the oil-immersed transformer needs to be drained. Only after that can the problem of the pressure equalizing cover be detected and located, but the treatment process of oil discharge treatment will pro...
