Description

An Improved Pole-mounted Disconnector Insulation Partition

technical field

The utility model belongs to the field of auxiliary tools for electric power construction, in particular to an improved insulation partition plate for a disconnect switch on a column.

Background technique

At present, factors such as complex overhead lines and dense equipment in the distribution network have resulted in a narrow range of live work, and live workers are in the process of replacing the isolating switch on the pole. The safety distance between the lead terminal and the ground is insufficient, and accidental short-term collisions or contact with grounding components are prone to occur, resulting in grounding short-circuit accidents. When using insulating blankets to insulate and shield the electrified body and the grounding body, it takes a lot of time to ensure that all parts are tightly shielded. One of the difficulties is to use insulating blankets to insulate and shield the upper and lower terminals of high-voltage knife switches and drop-out fuses. In the process of replacing high-voltage knife switches and drop-out fuses with electricity, when the upper and lower leads are separated from the high-voltage isolating switch and drop-out fuses, the live leads and terminals must be tightly shielded. It is difficult to ensure the 15cm overlap of the extended surface and reliable fixation of the lead wires when insulating blankets are used for shielding. The use of the insulating shielding cover can ensure the tight shielding and reliable fixing of all lead wires and terminals, prevent phase-to-phase and phase-to-ground short circuit accidents caused by loose shielding or loose fixation, and improve work efficiency and work safety.

Retrieve the existing patented technology: an insulating partition for a pole-mounted isolating switch (CN203932760U), which includes two insulating plates with symmetrical structures. In the docking combination, the wire grooves on both sides form the wire groove through holes, and a column is fixed on the upper part of the insulation board on both sides, and a lock hook is hinged in the middle of the column on one side; the outer side of the insulation board is fixed with a handle that is easy to hold. . The utility model can effectively shorten the operation time of replacing the isolating switch in live work through the development of the insulating partition of the isolating switch on the column, and improve the safety in the process of live working.

The above-mentioned insulating partition of the patent, because during the process of disassembling and installing the insulating partition, the operator needs to have both hands parallel to the partition, it is found in the application that the structure of the insulating partition of this structure is manually held by the handle structure, which is inconvenient for the actual operation. Finally, it is more convenient to install the handle on the outer edge of the partition instead of the vertical partition, and the wire groove structure and connection positioning structure on the two partitions in the prior art are also unstable.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide an improved post-mounted isolating switch insulating partition with simple structure, reasonable design, convenient use and strong practicability.

The utility model solves its technical problem and realizes by taking the following technical solutions:

An improved pole-mounted isolating switch insulating partition, including an upper insulating plate, a lower insulating plate, a wire slot, a limit splint, a positioning bolt and a hand slot, and the upper insulating plate and the lower insulating plate are connected in parallel to each other. Two grooves are symmetrically formed on both sides of the middle part of the joint between the upper insulation board and the lower insulation board. A splint is slid and embedded symmetrically at the ends respectively, and a positioning bolt is installed on the splint engagingly.

Moreover, two lower wire grooves are formed at intervals in the upper middle of the lower insulating plate, and an upper wire groove matched with the lower insulating plate is formed at the lower end of the upper insulating plate, and the upper wire groove and the lower wire groove are relatively buckled to form a complete oblong wire groove; The two lower wire grooves made by the lower insulation board are long holes matching the cable size, and the upper wire grooves made by the upper insulation board are two semi-arc wire grooves.

Moreover, an anti-slip protrusion is fixedly mounted on the top of the upper insulating plate and the lower insulating plate on the inside of the hand groove respectively.

Moreover, the positioning bolts adopt large insulating bolts.

Advantage and positive effect of the present utility model are:

1. The upper and lower ends of the insulating partition are provided with a hand-held structure with protrusions and through grooves, which is convenient for power distribution workers to carry out quick and safe operations while wearing insulating protective equipment.

2. The splint bolt type positioning structure is adopted on the partition, which is convenient for fixing the two insulating partitions, and the positioning is more stable, which can effectively prevent the discharge to the ground or the risk of falling objects caused by the loosening of the insulating partition during the operation process.

3. The utility model can effectively shorten the operation time of live work to replace the isolating switch, improve the safety in the live work process, and has a reasonable structure, more convenient operation, accurate positioning of the wire slot for the cable, and the fixing effect of the splint bolt positioning structure Good, and easy to operate, improve efficiency.
