Description

Cross arm shielding cover for uninterrupted operation Technical Field The utility model relates to the technical field of safety protection tools during operation of a power system, in particular to a cross arm shielding cover for uninterrupted operation. Background The cross arm shielding cover is key insulating protective equipment used for isolating the electrified cross arm in uninterrupted operation of the power distribution network, and can effectively reduce the risk of operators contacting electrified parts by covering the cross arm to form a physical isolation barrier on the surface of the cross arm. At present, the mainstream products in the market mostly adopt standardized size designs, namely, prefabricated shielding covers with fixed sizes according to the specifications of common cross arms, the designs are based on product shaping of statistical data of typical power lines, however, in practical application, it is found that the cross arms have obvious structural differences in different voltage level lines (such as 10kV and 35kV systems), different regional power grids (such as coastal and inland areas) and special line scenes (such as large spanning sections and old line reconstruction sections), the prior art means are to provide a series of products with different specifications for users to select, and the universality is not enough, when the actual size of the cross arms exceeds the design range of the shielding covers, the situation that the shielding covers cannot fully wrap the cross arms often occurs, so that the cross arm shielding covers with size self-adaptive adjusting functions are required to be developed, so that the cross arm shielding covers can be compatible with the geometric characteristics of the cross arms with different specifications, and the universality of shielding devices is improved on the premise that the insulation performance is ensured. Disclosure of utility model Based on the above description, the utility model provides a cross arm shielding cover for uninterrupted operation, which solves the technical problems pointed out in the background art.
