Background technique
In the power system, high-power transformer is the core equipment of entire power supply system, its failure by power supply can
Normal operation by property and system produces serious influence.Protection is a kind of protective device of oil-immersed transformer, is to become
Main guard block inside depressor, in the turn-to-turn and layer short circuit, iron core failure, inside pipe casing failure, winding to transformer
The failures such as portion's broken string and insulation degradation and pasta decline can sensitive action.Buchholz relay is mounted on transformer box cover and oil storage
In the connecting tube of tank, when breaking down inside oil-immersed transformer, since electric arc decomposes insulating materials and generates a large amount of gas
Body or when oil stream being caused to impact, acts the contact of Buchholz relay.Alarm signal is issued in time or cuts off transformer automatically, is protected
Protect the safe operation of equipment.
Once Buchholz relay alarm occurs, service personnel will arrive the gas in transformer field acquisition Buchholz relay
Body by judging the analysis of gas componant whether inside transformer has occurred the type of failure and failure, therefore acquires
The gas of Buchholz relay is particularly important.Gas is sent in collector box by transformer Buchholz relay by pipeline, tradition
Sampling method be that syringe and collector box are connected by moccasin pipe, the gas in collector box is extracted into syringe.This side
Method haves the shortcomings that following: (1) junction of hose and collector box, syringe does not have good sealing performance, is easy to happen gas
Leakage or outside air enter to polluting sample gas.(2) gas that Buchholz relay cannot be quantified, for judging transformer event
For barrier, lack the information of gas gross.
