Description

An insulated lever

technical field

The utility model belongs to the technical field of electric equipment, in particular to an insulating operating rod.

Background technique

The insulating operating rod is a unified name for insulating tools in the power system, and can be used for live work, live maintenance and live maintenance work tools. Insulated operating rods can be divided into 10KV, 35KV, 110KV, 220KV, 330KV, 500KV according to the voltage level. It is an applicable product developed according to the needs of power system production, operation and maintenance.

The inventor believes that the existing insulating operating rod has the following defects:

1) Existing high-voltage cables are often entangled with debris such as kites or plastic bags. At this time, electric workers need to climb the tower to clean up the debris. The process is complicated and may cause danger. The existing insulating operating rod only has function, and cannot be used to clean up debris on high-voltage cables.

2) The existing insulating operating rods are generally divided into interface type and telescopic type. The interface type insulating operating rod can only change the overall length of the insulating operating rod by increasing or decreasing the number of rod bodies; the rod body of the telescopic insulating operating rod generally does not exceed Five sections, otherwise the diameter of the outermost rod body will be too large. When the total length of the required insulating rod is 8-10m, the length of the single-section insulating rod is too long, which is not easy to carry.

3) The head of the existing insulating operating rod is divided into a fixed structure, and the angle of the head cannot be adjusted to adapt to different working conditions.
