Description

Mobile levers for substation equipment changer

technical field

The utility model relates to the technical field of replacing high-voltage power transformation equipment, in particular to a device for replacing power transformation equipment.

Background technique

Small-scale substation equipment below 220KV voltage level (such as 220KV support porcelain bottle, 110KV and below lightning arrester, 35KV knife switch, current transformer, voltage transformer, etc.) need to be repaired and replaced frequently, and the weight of these equipment is about 200Kg. The installation height is above 2.5m. There are mainly two ways to disassemble and replace it at present: one is crane operation, and the other is mast operation. There are three main defects in crane operation: First, live work requires a high distance, and all equipment within the swing range of the crane’s boom must be powered off before replacement operations can be started, and power failure will have adverse effects on economic benefits and social security; The second is the high rental cost of the crane, which increases the cost of equipment maintenance; the third is that the crane is large and often cannot be used due to site restrictions. The pole operation is to erect the pole next to the equipment that needs to be replaced, install a chain hoist on the pole, and use the chain hoist to lift the equipment to be replaced. There are three main defects: one is that the height of the pole cannot be adjusted, and the hoisting is difficult It is large and inconvenient to use; second, the density of live equipment around is high, and there is a risk of electric shock when installing the pole vertically, and the safety factor is low; third, the disassembly and assembly of the pole is very troublesome, with high labor intensity and low efficiency.
