Description

An insulating partition for a post-mounted isolating switch

technical field

The utility model belongs to the field of auxiliary tools for electric power construction, in particular to an insulating partition plate for a pole-mounted isolating switch.

Background technique

10kV distribution network overhead lines are complicated, equipment is dense and other factors result 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. When insulating blanket is used for shielding, it is difficult to ensure the 15cm overlap of the extended surface and reliable fixation of the lead wires. The use of the insulating shield can ensure the tight shielding and reliable fixing of all the 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.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a pole-mounted isolating switch 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 insulating partition for a pole-mounted isolating switch, comprising two insulating plates with symmetrical structures, and two semicircular arc-shaped wire grooves are evenly spaced in the middle of the insulating plates, and the wire grooves on both sides are formed when the two insulating plates are butted together The through hole of the wire slot is characterized in that: 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.

Moreover, the diameter at both ends of the column is greater than that in the middle.

Advantage and positive effect of the present utility model are:

1. The partition is equipped with a hand-held part on the insulating partition, which is convenient for the power distribution workers to carry out quick and safe operation while wearing insulating protective equipment.

2. A fixing device is set on the partition to facilitate the fixing of the insulation partition and prevent the loosening of the insulation partition during the operation process to cause discharge to the ground or the risk of falling objects from high altitude.

3. The utility model can effectively shorten the operation time of live work such as replacing the isolating switch through the development of the insulation partition of the isolating switch on the pole, and improve the safety in the process of live work.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the utility model.

An insulating partition for a post-mounted isolating switch, comprising two insulating plates 1 with symmetrical structures, two semicircular arc-shaped wire grooves 3 are evenly spaced in the middle of the insulating plates, and the two insulating plates are butted and combined so that the wires on both sides The through hole of the wire groove is formed by the groove, and the through hole of the wire groove is used to fix the cable.

The innovation point of the present utility model is:

A column 4 is fixed on the top of the insulation boards on both sides, and a lock hook 2 is hinged in the middle of the column on one side. The two insulation boards prevent short-circuit accidents to ground and accidents caused by falling objects due to loose shielding caused by insecure installation, improve the efficiency of live work and ensure the safety of work.

In order to prevent the locking hook from slipping off the column, the diameter at both ends of the column is greater than the diameter at the middle, as shown in accompanying drawing 2.

In order to facilitate the installation of the operator wearing insulating gloves, the outside of the insulating plate is fixed with a handle 5 that is easy to hold.

Although the embodiments and accompanying drawings of the utility model are disclosed for the purpose of illustration, those skilled in the art can understand that various replacements, changes and modifications can be made without departing from the spirit and scope of the utility model and the appended claims. It is possible, therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
