According to the utility model, the external surface of each bus body is provided with the sulfuration insulating layer, the safety of the bus is enhanced, distances between each two buses are shortened, and therefore the size of the switchgear body is reduced, and the manufacture cost of the switchgear is reduced.

Description

The bus structure of switch cubicle

Technical field

The utility model relates to switch cubicle, specifically a kind of bus structure of switch cubicle.

Background technology

In prior art, the bus of switch cubicle is exposed being arranged in switch cubicle directly, between exposed bus meeting and switch cabinet shell body, produces electric discharge phenomena, easily produces security incident, thereby affect reliability and the useful life of switch cubicle; In addition, because bus is exposed, have to strengthen the distance between each phase bus, cause switch cabinet body volume larger, manufacturing cost is higher.

Summary of the invention

The utility model, for the problems referred to above, provides a kind of bus structure of switch cubicle, and this bus structure fail safe is good, can dwindle the volume of switch cubicle.

According to the technical solution of the utility model: a kind of bus structure of switch cubicle, comprise the three-phase bus being formed by A phase bus, B phase bus and C phase bus, described three-phase bus comprises respectively the zigzag bus body being bent into by rectangular metal lath, the two ends of described bus body are respectively arranged with contact-making surface, on described contact-making surface, be processed with connecting hole, on the outer surface of described bus body except described contact-making surface, be provided with sulfuration insulating barrier.

On described contact-making surface, be provided with tin coating.

Described A phase bus is respectively arranged with auxiliary connecting hole with the middle part of the bus body of described B phase bus.

The contact-making surface junction, upper end of described three-phase bus is respectively arranged with insulating cover.

Technique effect of the present utility model is: the utility model is provided with sulfuration insulating barrier on the outer surface of each phase bus, increased the fail safe of bus, and can dwindle the distance between each bus, thereby reduce the volume of switch cabinet body, reduce the manufacturing cost of switch cubicle.
