Embodiment Construction

[0009] The present invention is not limited by the following examples, and specific implementation methods can be determined according to the technical solutions of the present invention and actual conditions.

[0010] Example: such as figure 1 As shown, the special insulating baffle for drop-out fuses is composed of two butt-connected insulating plates 2, the insulating plates 2 are in the shape of angle iron, and a semicircular notch 3 is provided at its opposite end, and the two notches 3 are butted to form a closed round hole. One corner of the opposite ends of the two insulating plates 2 is fixedly connected with the two clamp heads of the elastic clamp 4 respectively, and an insulating sheath is set on the hand-held part of the elastic clamp 4. The insulating clamp 2 is a market purchase part, and its structure is the same as that of a common clamp. The two pliers bodies are flexibly connected in a cross shape, and a spring is arranged between the pliers bodies of the ha...

Abstract

The invention relates to a special insulation barrier for a drop-out fuse protector, which comprises two butted insulating plates, wherein semi-circular notches are arranged on opposite sides of the insulating plates; the two notches are butt jointed to form a closed round hole; and one ends on the opposite sides of the two insulating plates are fixedly connected with two pincer heads of a pair of pincers. Due to implementation of the technical scheme, the special insulation barrier can reduce labor intensity, can control activity range of live working personnel more satisfactorily, and ensures safety of live line work.

Description

technical field [0001] The invention relates to a special insulating baffle for a drop-out fuse. Background technique [0002] Live work in power distribution is a working method that installs a large number of shielding appliances and maintains a corresponding safe distance on the basis of power outage operations. Operators wear insulating protective appliances, use insulating arm trucks to maintain insulation from the ground, and use intermediate potential methods to carry out operations . In the live work of the distribution network, the replacement of the drop-out fuse is a common project, and the development rate is relatively high. At present, there is no special insulating baffle for replacing the fuse in the live work of the power distribution network, and all are covered and isolated by insulating blankets. Since the shape of the insulation blanket is not fixed, the replacement operation is often affected during the operation, resulting in unpredictable dangers. ...
