Abstract
The invention discloses a high-voltage power capacitor hoisting device comprising a cross beam. A fixed clamp with the right-angle-7-shaped cross section is fixedly arranged at the right end of the cross beam, a long groove is formed in the upper surface of the cross beam in the length direction of the cross beam, a sliding block is slidably arranged in the long groove, and a movable clamp with the inverted-L-shaped cross section is arranged on the upper surface of the sliding block. A through hole is formed in the sliding block, a hole feature is formed in the position, corresponding to the through hole, of the long groove, and the sliding block and the long groove are fixed through a fastener arranged in the through holes; and a T-shaped groove is formed in the lower surface of the cross beam in the length direction of the cross beam, two guide rails are arranged on the two shoulders of the T-shaped groove in the length direction of the T-shaped groove correspondingly, a roller set is arranged on the guide rails in a rolling mode, a connecting rod is rotationally arranged on a rotating shaft of the roller set, and a chain block is connected to the lower end of the connecting rod. The high-voltage power capacitor hoisting device is suitable for assembling and disassembling a parallel capacitor bank in a converter station, the problem that the replacement efficiency of a high-voltage power capacitor is low is solved, and meanwhile, great safety risks caused by field overhauling operation are greatly reduced.
Description
technical field [0001] The invention belongs to the technical field of power equipment hoisting, in particular to a high-voltage power capacitor hoisting device. Background technique [0002] The converter valves in the converter station consume a large amount of reactive power during operation. In order to realize the local balance of reactive power, the converter station is equipped with multiple sets of AC filters and parallel capacitor banks to provide reactive power. Capacitors, as the basic components of AC filters and shunt capacitors, are numerous in converter stations. [0003] Fault phenomena such as capacitor oil leakage, capacitance value change, and joint heating occur frequently during operation. In order to eliminate equipment defects, it is necessary to cut off the power to replace the faulty capacitor. After the wiring of the faulty capacitor is removed, it is moved out of the installation location, and a new qualified capacitor is moved into the installati...
