Problems solved by technology
At present, there is no shielding tool used in the 10kV distribution network with load to replace the high-voltage side lead wire of the transformer. When using insulating cloth for shielding, there are electrified parts that are not completely covered or covered and the operator's movements are large, resulting in relative ground short circuit or simultaneous contact. Accidents are prone to occur when there are two-phase charged bodies, and the work procedures during the construction process are complex and prone to personal equipment accidents, and even directly cause casualties

The invention discloses an insulating cover for on-load replacement of a transformer high-voltage side lead. The insulating cover is characterized by comprising an insulating main body (1) and an insulating secondary body (2), wherein the insulating main body (1) comprises two insulating phase partitions (1-1), a main body insulating phase-earth partition (1-2) is connected between the insulating phase partitions (1-1), a U-shaped transformer knob insulator clamping groove (1-3) is formed in the main body insulating phase-earth partition (1-2), the insulating secondary body (2) comprises a space partition (2-1) which is perpendicularly connected with an insulating phase-earth partition (2-2), and a U-shaped transformer knob insulator clamping groove (2-3) is formed in the insulating phase-earth partition (2-2). The insulating cover is simple in structure, safe, reliable and applicable to transformer high-voltage side lead on-load replacement work, personnel can have control over the movement range when carrying out distribution transformer high-voltage side lead on-load replacement work, redundant complex shielding measures are omitted, the safety factor is increased, working efficiency is improved, and safety of live working is ensured.
Description
Technical field: [0001] The invention relates to an insulating cover, in particular to an insulating cover for replacing lead wires at the high-voltage side of a transformer with load. Background technique: [0002] Live work on power distribution overhead lines can not only avoid power outages for users, but also has more flexible working hours. With the continuous improvement of social and economic requirements for power supply reliability, the projects and scope of live work on power distribution lines have been expanding year by year. In recent years, due to the increase of residential users and the increase of user power load demand, the cross-section of the distribution transformer lead wire cannot meet the requirements of the power supply load, and it is urgent to replace the lead wire with a large cross-section. But now power supply enterprises have very few live work projects for transformers, and the technology is immature and there are no special tools. At presen...
