The portable power transformer tapping switch adjusting device is advantageous in that the fast shift adjustment of the tapping switch can be realized by the transformer tapping switch control case, when the control case is not wired for the second time or the DC power supply is not provided, and therefore the labor force can be saved; the detention time of the wire changing personnel on the transformer can be reduced, and the safety coefficient of the operators can be improved; the tapping positions can be adjusted repeatedly, and the influence of the transformer tapping switch oil film on the transformer DC resistor can be eliminated, and the accuracy of the testing efficiency and the testing data of the transformer can be improved; the portable performance is good, and the popularization and the application can be facilitated by using the single-phase power supply, and the time-consuming problem and the labor-consuming problem of the manual adjustment of the tapping switch can be solved, and the working efficiency can be improved.
Description
Technical field
The utility model 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 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 on load tap changer can't be used its electric device carried 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 normal condition, carrying out the test of Three-Phase Transformer D.C. resistance needs about 2 hours, and when indivedual gear test datas are abnormal, test duration needs the time of more growing.Get rid of as need the data deviation that shunting switch inner " oil film " causes, need to repeatedly adjust each section gear, increase the testing time.Surveying by statistics one has while carrying the Three-Phase Transformer D.C. resistance and need to manually shake the 2000-2500 circle, to the larger length consuming time of cooperation personnel muscle power overdraw of manual adjustment shunting switch.
The utility model content
For above-mentioned problems of the prior art, a kind of portable power transformer shunting switch adjusting device of efficient quick is provided, solved in prior art and had the sub-connecting switch of transformer operating efficiency of carrying low, the activity duration is long, the problem that labour intensity is large.
The utility model solves the technical scheme that its technical problem adopts:
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 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 beneficial effects of the utility model are, have adopted monopole asynchronous motor that power is provided, and utilize positive and negative switch to realize the adjusting of gear, and 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 can get rid of the impact of sub-connecting switch of transformer oil film on DCR of Transformer, improved the accuracy of transformer test efficiency and test data.Good portability, use single phase poaer supply have been convenient to promote the use of, solve the shunting switch predicament that manually adjustment is wasted time and energy, and increase work efficiency.
