Meanwhile, Buchholz relay is the important technique measure of protection oil-filled transformer safe operation, has the advantages such as highly sensitive, installation wiring is simple.But the faults such as oil impregnate easily appear in Buchholz relay, this just need to carry out regular detection to it.Gas relay calibration detection device is mainly the gas-actuated relay calibration stand in laboratory at present, by gas-actuated relay calibration stand at laboratory simulation actual operating mode, promote the baffle plate action of Buchholz relay by the uninterrupted of electric pump control medium oil, carry out the flow working value of Buchholz relay and demarcate, thereby calibration detects to Buchholz relay.Although this kind of device is feasible, but it is because use electric pump and Medium Oil, larger and the easy contaminated environment of its volume, under laboratory environment, carry out in addition, for the scene of common electric power apparatus examination, this testing calibration device cannot carry out field calibration, and its calibration cycle is longer, work efficiency is lower, is unfavorable for substation equipment maintenance and repair and field failure judgement.
Utility model content
The purpose of this utility model is to provide the device of the leakage of oil of a kind of Site Detection transformer and Buchholz relay warning performance, and this device not only can Site Detection transformer and whether leakage of oil of Buchholz relay, detect accurately, and fast and easy, authenticity is high; And do not need the uninterrupted of electric pump control medium oil, can detect really the performance of Buchholz relay.
For solving the problems of the technologies described above, the technical solution of the utility model is: the device of the leakage of oil of a kind of Site Detection transformer and Buchholz relay warning performance, comprise the three-way connection matching with Buchholz relay one end, on every end of described three-way connection, operation valve is all set, one end of described three-way connection is connected with electric air pump by conduit, electric air pump is connected with controller, in described three-way connection, be provided with gas flow sensor and pressure transducer, described gas flow sensor is all connected with controller with pressure transducer.
Described controller is connected with alarm.
Described operation valve adopts Unidirectional solenoid valve, and Unidirectional solenoid valve is connected with controller.
The utility model is in use by auxiliary fuel tank valve closing, three-way connection is arranged under Buchholz relay, transformer oil pipe is connected on three-way connection, closed control valve 1, open electric air pump, open operation valve 8 and operation valve 9 simultaneously, gas flow sensor and pressure transducer send to controller to show the pressure of output gas flow and flow, gas atmosphere while recording Buchholz relay action connection point by pressure transducer and transformation period, also gas flow and transformation period while recording Buchholz relay action connection point by flow sensor simultaneously, whether contrast Buchholz relay performance is up to standard, connect and detect light gas leakage alarming device and whether work and weigh gas leakage device and whether work by controller regulation output gas flow, whether close auxiliary fuel tank end valve door, detect Buchholz relay and leak, set gaseous tension and voltage-withstand test time by controller, when reaching the voltage-withstand test time, pressure is unchanged, proves that gas relay sealing property is good, closed control valve 9, open electric air pump, open operation valve 8 and operation valve 1 simultaneously, set gaseous tension and voltage-withstand test time by controller, when reaching the voltage-withstand test time, pressure is unchanged, prove transformer good seal performance, work as pressure drop, signal is transferred to controller by pressure transducer, and controller starts alarm equipment alarm.Therefore, comprehensively above-mentioned, the utility model device not only can Site Detection transformer and whether leakage of oil of Buchholz relay, detect accurately, and fast and easy, authenticity is high; And do not need the uninterrupted of electric pump control medium oil, can detect really the performance of Buchholz relay.
