Description

Power transformer gas collector
Technical field
This utility model relates to a kind of power transformer gas collector.
Background technology
It is always relatively difficult that power transformer Buchholz relay takes gas work, it is equipped with negligible amounts as well as collector, some transformer station is even without special collector, once there be gas to enter into inside Buchholz relay, taking-up gas censorship at short notice can not be accomplished, cause that gas different component back dissolving phenomenon occurs, affect the testing result of gas, it is impossible to the correct character assessing power transformer interior fault and the order of severity, development speed and trend.
Take now the method that gas adopts and remain use: injector for medical purpose, mosquito forceps, the combination of tourniquet.This method has Railway Project: first, complex operation: once step is wrong, takes gas operation failure, and the gas in gas relay is limited, is impermissible for waste.Loaded down with trivial details step, even if the person on duty known a thing or two also cannot accomplish skillfully to take gas.Second, operation easier is big: the old-fashioned gas method that takes needs the longer operating time, takes gas operation and is inherently in operation under high altitude environment, and transformator upper space is limited, this brings very big inconvenience to the gas work that takes of person on duty and professional and technical personnel, is unfavorable for carrying out and carrying out of work.3rd, one man operation is inconvenient, owing to glass syringe is very frangible, the process carrying out extraction gas not only to observe practical situation in conduit, also after taking gas, to block with mosquito forceps rapidly, gas process needs accomplish that multiple step tightly coordinates whole taking, once careless and inadvertent, cause that taking makings amount deviation occurs, affects testing result.4th, after getting experimental gas with glass syringe, due to the fragility of glass, it is unfavorable for transport and preserves, and the sealing property of glass syringe is bad, of long duration, internal gas sampled can swap with extraneous gas, can affect the final result of experiment.
Utility model content
The purpose of this utility model is to solve lack special power transformer Buchholz relay collector at present and take complex steps, the inaccurate problem of result that gas operation exists, and proposes a kind of power transformer gas collector.
A kind of power transformer gas collector, its composition includes: vent valve, A conduit, rubber seal device, B conduit and gas-storing bag;Vent valve has the vent valve knob of control gas discharging, the gas relief valve connecting power transformer and the gas leadout hole being attached with A conduit;One end of A conduit connects with gas leadout hole, the other end fixed installation syringe needle of A conduit;B conduit is installed only air cock, the fixing connection in one end of B conduit gas-storing bag, the other end of B conduit fixing connection rubber seal device;
During duty, the syringe needle that A conduit is installed is inserted in rubber seal device, makes A conduit connect with B conduit.
The beneficial effects of the utility model are:
This utility model simplifies operating procedure, accelerates and takes gas speed, decreases because gas back dissolving affects the component detection of gas, it is to avoid the dissipation amount of taken gas, it is ensured that the reliability of testing result.
It is simpler that this utility model makes to take gas work, letter and understandable operating procedure fundamentally solves an operational difficult problem, it is possible to one man operation, solve the unfavorable keeping of gas, the problem of transport inconvenience.
Owing to this utility model volume is little, convenient storage, simple to operate easy to learn, it is suitable for person on duty and technical staff uses, and also cheap, volume production is convenient.
