Description

10kV Line Dropout Fuse Insulation Partition

technical field

The utility model relates to an insulating partition, in particular to an insulating partition for a 10kV line drop-out fuse, which belongs to the technical field of electric power industry.

Background technique

At present, during the use of outdoor 10kV high-voltage line drop-out fuses, faults such as burning, deformation, and pressure spring fatigue of the dynamic and static contacts often occur due to heating between the dynamic and static contacts. At this time, the high-voltage drop-out fuse must be pulled apart, and replaced by the intermediate potential method (insulating glove operation method) using an insulating bucket truck. After the 10kV high-voltage drop-out fuse is opened, since the static contact is directly connected to the side of the drain wire, the distance between the static contact and the connected live part and the grounding part of the fixed fuse is only 11cm-13cm, which is far lower than that in the "Power According to the national standard of 0.4m safety distance below 10kV stipulated in the Safe Work Regulations, the connection between the static contact and the drain line must be loosened when replacing the fuse. Insulation and isolation measures for live parts and grounding parts of fixed fuses. At present, the insulation and isolation measures adopted generally have the following two methods: 1. After wrapping the grounding part with a resin insulating blanket, fix it with an insulating clip; 2. After wrapping the grounding part with a rubber insulating blanket, fix it with an insulating clip. The above method has the following problems: one is to use resin or rubber insulating blanket for shielding, because the material is not tightly wrapped, leaving gaps, it is easy to cause grounding accidents during the operation; the other is to use resin or rubber insulating blanket for shielding. During the operation, the operator's hands are carried between the charged body and the grounded body. Due to the narrow space, it is easy to touch the charged body and the grounded body at the same time, resulting in personal accidents. Third, the operation is cumbersome, the operation time is long, and the work efficiency is low.

Contents of the invention

The purpose of this utility model is to provide a 10kV line drop-out fuse insulating partition, which is a safe, reliable, Convenient and fast masking tool. It can effectively isolate the electrified body and the grounding part to ensure the safety of the operators, and the operation is simple, convenient and quick.

The technical scheme of the utility model is: a 10kV line drop-out fuse insulating partition, which is composed of an insulating plate, a left U-shaped chute plate, a right U-shaped chute plate, and a slide plate. An insulating plate opening (6) is processed on the insulating plate (1), a left U-shaped chute plate (2) is bonded on the left side of the insulating plate opening (6), and a right U-shaped chute plate (2) is bonded on the right side of the insulating plate opening (6). Type chute plate (3), slide plate (4) is housed in the right U-shaped chute plate, is equipped with slide plate button (5) on slide plate (4).

The beneficial effect of the utility model is that: because the epoxy resin plate with high insulation strength is used to make the insulating partition of the 10kV line drop-out fuse, the work is safe and reliable, and the charged part can be effectively isolated from the grounding part to ensure the charged part. The safety of the operating personnel, the operation is simple, the work efficiency is greatly improved, and the quick response and fast operation are realized, which has extensive practical value.

Detailed ways

Please refer to Figure 1, 10kV line drop-out fuse insulation barrier, which is composed of insulation plate, left U-shaped chute plate, right U-shaped chute plate, and slide plate. An insulating plate opening (6) is processed on the insulating plate (1), a left U-shaped chute plate (2) is bonded on the left side of the insulating plate opening (6), and a right U-shaped chute plate (2) is bonded on the right side of the insulating plate opening (6). Type chute plate (3), slide plate (4) is housed in the right U-shaped chute plate, is equipped with slide plate button (5) on slide plate (4).

Instructions

When it is confirmed that the drop-out fuse is faulty and needs to be repaired, disconnect the 10kV high-voltage drop-out fuse that needs to be repaired or replaced, and check that the fuse tube has fallen and there is no foreign object. At the pole drop switch, align the insulating plate opening (6) on the insulating partition between the static contact and the insulator grounding part of the fixed fuse and insert it. Since the size of the insulating plate opening (6) has been designed in advance, pull it out Slide the slide plate button (5) to slide the slide plate (4) from right to left until the opening of the insulating plate (6) is closed and stabilized. After confirming that the insulating plate is firmly placed and the live parts are completely and effectively isolated, the static contact can be carried out. After the live maintenance work is completed, pull the slide button (5) to slide the slide plate (4) from left to right until the insulation plate opening (6) is opened, and then take off the live work insulation partition. The main material of the 10kV high voltage line dropout fuse insulation partition is a 5mm thick epoxy resin board, which is suitable for 10kV high voltage maintenance live work, and the withstand voltage test is 35kV/60S, which meets the national regulations.
