Special partitioning switch lifting device

Abstract

The invention discloses a special partitioning switch lifting device which comprises an upright column, wherein the upright column consists of a support rod and a support tube which is arranged at thebottom of the support rod in a sleeving manner; two groups of electric rod stayed cables which are arranged up and down are arranged on the side wall of the support tube; the two groups of the electric rod stayed cables are arranged left and right respectively; the electric rod stayed cables consists of pull rods and hoops which are arranged at outer ends of stayed cables; a motor is arranged onthe support rod; a reel is arranged at the output end of the motor; a lifting rope is wound on the reel; a horizontal lifting arm is fixedly arranged at the top of the support rod; pulleys are respectively arranged at the front end and the rear end of the bottom of the lifting arm; the free end of the lifting rope passes through the pulleys from back to front and falls down freely at the front endof the lifting arm; two ropes are led out from the free end of the lifting rope; hooks are respectively arranged at outlet ends of the two ropes of the lifting rope. By adopting the special partitioning switch lifting device, the floor space can be reduced, ambient orographic influence can be avoided, and partitioning switches can be conveniently lifted up.

Description

technical field [0001] The invention relates to disassembly and assembly equipment for isolating switches, in particular to a special lifting device for isolating switches. Background technique [0002] With the rapid growth of the regional economy, the demand for electricity has also increased sharply, and it is urgent to expand the substation by increasing the line interval. At the same time, in order to ensure the safe and stable operation of the entire power grid, the disconnector also needs to be overhauled in accordance with relevant regulations. Whether it is new addition or overhaul, there are generally two construction plans for isolating switches: one is busbar power outage construction. Although this method is relatively safe, it is difficult to determine the construction time, the workload is huge, and there is a great threat to the reliability of power supply. Therefore, This program has been phased out. The second is the live construction of the busbar, which...

Problems solved by technology

Whether it is new addition or overhaul, there are generally two construction plans for isolating switches: one is busbar power outage construction. Although this method is relatively safe, it is difficult to determine the construction time, the workload is huge, and there is a great threat to the reliability of power supply. Therefore, The program has been phased out

The second is the live construction of the busbar, which is hoisted and installed by a crane without power failure. Due to the large area occupied by the crane, affected by the terrain around the construction, the crane cannot enter, and the operation of hoisting the isolation switch is extremely inconvenient
