Abstract
The invention relates to a portable power transformer tapping switch adjusting device capable of rapidly adjusting an on-load transformer tapping switch. As for the structure of the portable power transformer tapping switch adjusting device, a fixing support is arranged on a body, a forward and reverse rotation switch and a power source control switch are arranged on one side of the body, a single-phase asynchronous motor is arranged in the body and is connected with a capacitor and a transmission gear, and the transmission gear is connected with a transmission plug. The portable power transformer tapping switch adjusting device can achieve the fact that gears of the tapping switch are adjusted rapidly under the circumstance that a transformer tapping switch control cabinet is not wired or does not have a direct current power source for the second time, and manpower is saved. Residence time for wire replacement staff on a transformer is shortened, and the security coefficient of the operation staff is enhanced. The tapping positions can be adjusted repeatedly, practice shows that influences on direct-current resistance of the transformer from an oil film of the transformer tapping switch can be eliminated, and testing efficiency and accuracy of testing data of the transformer are enhanced. The portable power transformer tapping switch adjusting device is good in portability, is convenient to popularize and use due to use of a single-phase power source, solves the problem that manual adjustment of the tapping switch wastes time and labor, and enhances work efficiency.
Description
Technical field
The present invention is a kind of device of adjusting sub-connecting switch of transformer, and relating in particular to a kind of energy rapid adjustment have the portable power transformer shunting switch adjusting device that carries sub-connecting switch of transformer; Can be widely used in power transformer load tap changer test and the upkeep operation.
Background technology
Electric power system has live power transformer in the operation process such as test, maintenance.Power transformer is in power down mode.The loaded switch side is supplied with motor without three phase mains simultaneously, and namely on load tap changer can't use its electric device that carries to adjust each section tapping gear, at this moment must use the manual rocking bar of shunting switch, and manually hand 30 circles of rocking bar are a tap position.Manual regulation tap switch under the normal condition, carrying out the test of Three-Phase Transformer D.C. resistance needs about 2 hours, and when indivedual gear test datas were unusual, test duration then needed time of more growing.Get rid of the data deviation that shunting switch inner " oil film " causes such as need, need to repeatedly adjust each section gear, increase the testing time.Surveying by statistics one has and need to manually shake the 2000-2500 circle when carrying the Three-Phase Transformer D.C. resistance, to the larger length consuming time of cooperation personnel muscle power overdraw of manual adjustment shunting switch.
Summary of the invention
For above-mentioned problems of the prior art, a kind of portable power transformer shunting switch adjusting device of efficient quick is provided, having solved has the sub-connecting switch of transformer operating efficiency of carrying low in the prior art, and the activity duration is long, the problem that labour intensity is large.
The technical solution adopted for the present invention to solve the technical problems is:
Body is provided with fixed support, and a side of body is provided with forward-reverse switch and power control switch, is provided with monopole asynchronous motor in the body, and monopole asynchronous motor is connected with electric capacity and travelling gear, and travelling gear is connected with the transmission plug.
Described fixed support is flexible adjustable fixed support.
Described forward-reverse switch is the HY2-30 order switch.
Described electric capacity comprises start-up capacitance and operation electric capacity.
The power transmission shaft of described transmission plug and shunting switch is complementary.
The invention has the beneficial effects as follows, adopted monopole asynchronous motor that power is provided, utilize positive and negative switch to realize the adjusting of gear, support bracket fastened length can be regulated according to the shunting switch control cabinet of different model.Can realize the sub-connecting switch of transformer control cabinet, secondary in wiring or the situation without DC power supply, does not carry out the quick adjustment tap changer gear, saves manpower.Reduction transformer top thread-changing personnel's residence time, improve operating personnel's coefficient of safety.Repeatedly adjust tap position, facts have proved and to get rid of the sub-connecting switch of transformer oil film to the impact of DCR of Transformer, improved the accuracy of transformer test efficient and test data.Good portability, use single phase poaer supply have been convenient to promote the use of, solve the predicament that the manual adjustment of shunting switch is wasted time and energy, and increase work efficiency.
