Online monitoring device collector for transformer bushing oil

Abstract

The invention provides an online monitoring device collector for transformer bushing oil. The online monitoring device collector comprises a main body base, a hydrogen transmitter module, a pressuretransmitter module, an oil drain valve and an adapter; the top of the main body base is provided with the hydrogen transmitter module; the pressure transmitter module and the oil drain valve are distributed on the two sides of the main body base; a seal seat is arranged at the bottom of the main body base; the adapter is arranged on the seal seat in a sleeving mode; the seal seat is further sleeved with a connecting and fixing sleeve; a containing cavity for containing the upper end of the adapter is formed in the lower surface of the connecting and fixing sleeve; a plurality of fixing holes are distributed in the circumferential direction of the containing cavity; fastening screws are in threaded connection with the interiors of the fixing holes; and the fastening screws can be tightly pressed on the side walls of the upper end of the adapter. The online monitoring device collector realizes online monitoring of hydrogen and an oil pressure in the transformer bushing oil, and has the advantages of no power failure and real-time monitoring and diagnosis.

Description

technical field [0001] The invention specifically relates to a collector of an online transformer bushing oil monitoring device. Background technique [0002] Power oil-filled equipment, such as transformer bushings, oil-immersed current transformers, voltage transformers, and oil-less circuit breakers, is one of the main equipment in the power system and plays a pivotal role in the power system. Failure or damage of oil-filled equipment will not only cause power outages, but may even cause substation equipment to explode or even cause a fire, further expanding the scope of the accident. The safe and stable operation of oil-filled equipment directly affects the stability of the entire power grid, and it is of great significance to the diagnosis and evaluation of the insulation status of oil-filled equipment. [0003] For the insulation state diagnosis of oil-filled equipment, traditional high-voltage electrical tests such as dielectric loss and capacitance tests have relati...

AI Technical Summary

Problems solved by technology

[0003] For the insulation state diagnosis of oil-filled equipment, traditional high-voltage electrical tests such as dielectric loss and capacitance tests have relatively simple means, and the test data is easily affected by test conditions, reflecting less insulation information, and requires power outages and long test periods.
