Abstract

The invention provides a high-voltage isolating switch hoisting device, which includes a rotating module, a supporting module, a fixing module and a balancing module; the rotating module includes a hook, a hook power mechanism, a horizontal boom, and a rotating Bearings; the support module includes a vertical upper boom bar and a vertical lower boom bar; the fixed module includes a fixing device, a limiter and a rod puller; the balance module includes a horizontal bar. The invention has the advantages of simple and convenient adjustment of hoisting height, safe and reliable operation, and high efficiency. Two people can disassemble, assemble and construct. At the same time, its load can reach 200 kg, which meets the requirements for hoisting high-voltage isolating switch components on site.

Description

technical field [0001] The invention relates to a hoisting device for a high-voltage isolating switch. Background technique [0002] In the power system, the isolating switch in the substation has a serious impact on the reliability of power supply due to the increasing operating time limit, serious corrosion, increased defects and insufficient capacity of the main conductive circuit. It is urgent to carry out corresponding technical transformation on the isolating switch that has been in operation for a long time. In the transformation process, in order not to affect the user's power supply, the corresponding interval power failure transformation is usually adopted, and the other intervals continue to operate with electricity. In such an operation mode, it is often encountered that the distance between the isolating switch that needs to be modified and the live equipment is too close to meet the sufficient safety distance required for on-site crane hoisting, and because of ...
