Description

Technical Field

[0001] The utility model relates to the technical field of live working insulation shielding equipment, in particular to a wire insulation shielding cover. Background Art

[0002] In the live line lead disconnection operation of the 10kV distribution network non-stop insulation pole operation method, in order to prevent phase-to-phase short circuit and grounding, wire shielding covers and insulator shielding covers must be used for insulation shielding. Traditional wire shielding covers must be pulled down with relatively large force during use to install the wire shielding cover to complete the insulation shielding. When removing the insulation shielding, relatively large force must be used to push up. Excessive force can easily cause the wire to swing too much, which can easily lead to phase-to-phase short circuit, or cause old, outdated, and small lines to fall, causing accidents. Secondly, because it is not easy to hang, the large force during operation leads to a high rate of wear. Therefore, the usage rate is not high and it is difficult to be widely promoted. It can only be used for training and has not been effectively used on site.

[0003] The existing application number is 201420519773.6 for live working on power conductors, comprising an inner insulating shielding cover, an inner insulating shielding cover connecting block is fixed on the outer side of the inner insulating shielding cover, an inner insulating shielding cover hanging ring that cooperates with an insulating rod is fixed on the inner insulating shielding cover connecting block, an outer insulating shielding cover with the same axis as the inner insulating shielding cover is sleeved on the outer side of the inner insulating shielding cover, an outer insulating shielding cover connecting block is fixed on the outer side of the outer insulating shielding cover, an outer insulating shielding cover hanging ring that cooperates with the insulating rod is fixed on the outer insulating shielding cover connecting block; a telescopic slide rail is provided between the inner insulating shielding cover and the outer insulating shield, and the telescopic slide rail is respectively fixedly connected to the outer side of the inner insulating shielding cover and the inner side of the outer insulating shielding cover. The method of use is as follows: the operator places the inner insulating shielding cover and the outer insulating shielding cover at the appropriate position where the wire needs to be shielded, uses the insulating rod to hook the outer insulating shielding cover hanging ring and the inner insulating shielding cover hanging ring, pushes the outer insulating shielding cover and the inner insulating shielding cover to the appropriate position along the telescopic slide rail, and then uses the rear end positioner to lock the inner insulating shielding cover, and uses the front end positioner to lock the outer insulating shielding cover. When the live work is completed and the insulating equipment is recovered, the operator opens the rear end positioner and the front end positioner in turn, and then uses the insulating rod to hook the outer insulating shielding cover hanging ring and the inner insulating shielding cover hanging ring, and uses the telescopic slide rail to retract, return to the original position, and remove the inner insulating shielding cover and the outer insulating shielding cover. In addition to the above-mentioned deficiencies of conventional conductor shielding covers, the insulating shielding cover for live working on power conductors also has the following deficiencies: 1) the insulating shielding cover has an opening, which causes the conductor to be in an incompletely shielded state, resulting in poor insulation shielding effect; 2) the insulating shielding cover is operated by hooking a hanging ring on the insulating rod, so that the insulating shielding cover is put on the conductor through the opening. On the one hand, due to the small opening, it is difficult to align the insulating shielding cover with the conductor, and the installation is difficult. On the other hand, the installation and removal also require the operation of a positioner, which makes the installation and removal operations troublesome. Utility Model Content
