Problems solved by technology

[0005] In order to solve the test and inspection work of various types and models of high-voltage equipment in the power system in the prior art, the present invention uses the bus bar as the connecting wire, and the height of the bus bar needs to be continuously adjusted when changing the tested product. It also needs to be connected with a step-up transformer, and the connection method of high-voltage equipment is relatively complicated. Every time the test conditions or the equipment under test are changed, a large amount of repetitive work will be faced, resulting in the problems of low utilization rate of test equipment, high labor intensity and low work efficiency. Then a kind of active power transmission device for high voltage test busbar is proposed

Abstract

The invention discloses a bus movable power transmission device, relates to a power transmission device and aims at solving the problems of low utilization rate of test devices, great labor strength and low working efficiency caused due to a large quantity of repeated work when changing test conditions or tested devices for each time since a bus serves as a connection guide wire when testing and checking various types and various models of high-voltage devices of a power system in the prior art, the height of the bus needs to be adjusted continuously when replacing the tested articles, the bus also needs to be connected with a boosting transformer before testing for each time, and the connection manner of the high-voltage devices is complicated. The device comprises a bus, a boosting transformer, a boosting transformer connector, a transmission connection mechanism, a fixing mechanism and two lifting mechanisms, wherein the fixing mechanism comprises two portal frames; the lifting mechanisms comprise winches, lifting frame cross beams, two cable ropes and two insulators. The bus movable power transmission device is applicable to high-voltage test of a power system.

Description

technical field [0001] The invention relates to a power transmission device, in particular to a movable power transmission device for a high-voltage test bus. Background technique [0002] At present, with the increasing demand for long-distance power transmission, the voltage level of the power system continues to increase. The testing and inspection work of various types and models of high-voltage equipment in the prior art is becoming more and more heavy.
