Description

Hookable insulating rod

technical field

The present invention relates to a hookable insulating rod.

Background technique

In order to improve the reliability of power supply and high-quality service level, the live work team of the Transportation, Distribution and Inspection Center has continuously strengthened basic management and safety management, and actively carried out live work innovation work, which is important for ensuring the safe, stable and reliable operation of the power grid, reducing power loss and improving customer satisfaction. have played a very important role.

In our long-term work, we found that the user access points and some branch line segments of the distribution network are also controlled and protected by drop-out fuses. These devices have been put into operation for a long time or have been overloaded. The damage rate of the drop-out fuse is very high, which is usually manifested in the burning and fusing of the upper and lower pile heads of the drop-out fuse of a certain phase, and it is often an emergency fault defect. Once these emergency failures occur, all users on the back side will be in a power outage state, and emergency repair and restoration must be organized immediately.

The operation of replacing a certain phase drop-out fuse by using the live work of the intermediate potential of the insulated bucket truck, in order to pursue the timeliness of emergency repairs, and strive for the time for power transmission. Usually, it is not necessary to remove the wire clip on the main wire, but to disassemble the upper pile head lead of the phase drop-out fuse, and then fix it with an insulating lock rod, which is held by an operator (or tie the wire back to On the same-phase main line), another person performs the replacement method work. Therefore, the insulating lock rod is an insulating tool that is used very frequently. But in practice, we found that there are some imperfections in the insulating lock rod.

However, there are two very obvious shortcomings in the use of insulating lock rods that can be purchased on the market at this stage:

①After locking the live drain wire with the insulating lock rod, one operator must hold the insulating lock rod, and the other operator must replace the drop fuse. During the replacement process, especially after dismantling the insulation shielding measures, the insulation lock rod is responsible for the main insulation at this time. The operator who holds the insulating lock rod in his hand must not form a circuit with the replacement operator, and can never perform other auxiliary work.

②If the operator who replaces the drop fuse needs to adjust the position of the insulated bucket truck to reach a more suitable position. In the process of turning the bucket and the arm of the insulated bucket truck, the continuous adjustment of the working bucket may cause the hand-held insulating lock rod to fall off, causing a major safety hazard.
