Problems solved by technology

However, in the prior art, the two test structures are set separately, which increases the cost of the short-circuit or open-circuit test, and takes up a lot of space, making it impossible to realize the structural arrangement in the case of a small project space

Abstract

The invention proposes a phase isolated bus contact structure, and relates to the field of power transmission equipment. The structure comprises a maintenance cover 3, a maintenance seat 6, a bus shell 5, a contact cylinder 1 and a contact sheet 2. With the adoption of the contact cylinder 1 being of a round top structure, the contact sheet 2 for maintenance grounding is welded with the top of thecontact cylinder 1 on the premise that the application of a short-circuit test contact is not affected, so that a short-circuit maintenance interface and a maintenance grounding interface are combined in one, the manufacturing cost is reduced, the space occupied by the structure is relatively small, and the structure can be applicable to narrow space arrangement of a project and is high in applicability.

Description

technical field [0001] The invention relates to the field of power transmission equipment, in particular to a contact structure suitable for both short-circuit test and maintenance grounding. Background technique [0002] In the off-phase busbar system, due to functional requirements, the off-phase busbar needs to be equipped with a short-circuit test device and an inspection grounding device. Patent CN204166011U discloses a short-circuit conductor connection structure of isolated-phase closed busbar short-circuit test conductor connection structure. The busbar conductors are all welded with fixing seats, and bolt holes are opened on the fixing seats. The short-circuit test conductors are connected by bolt and nut assemblies. Complete the short-circuit test on the fixed seat of the busbar. Figure 5 It is the detailed drawing of the traditional maintenance grounding device, Figure 5 Among them, the busbar conductor is welded with a grounding transition bar, which is connect...
