Vertical lifting-type high-security double-power supply device

Abstract

The invention discloses a vertical lifting-type high-security double-power supply device, which comprises a bracket, busbar-integrated insulating contact boxes, lifting mechanisms and a handcart, wherein a vertical beam is arranged in the middle of the bracket; the busbar-integrated insulating contact boxes are fixedly arranged at one side of the top of the bracket; the lifting mechanisms are arranged at two sides of the vertical beam of the bracket; and the handcart is arranged on a support plate and bears a plurality of side outlet pole posts and execution mechanisms. Busbars are integrally coated with an insulator, and location and insulation of the busbars are achieved by using the insulator, so that the use security is improved; the busbars are directly connected with an inlet end and an outlet end, for example, the inlet end and the outlet end and the busbars are in integral formation or welded connection, so that threaded connection is reduced and the insulating treatment difficulty of the connected part is reduced; especially, the busbars are connected with the inlet end and the outlet end and then cast, and the connected part is naturally shielded, so that the after-treatment difficulty is reduced and the reliability is improved.

Description

technical field [0001] The invention relates to the technical field of dual-power switching equipment and a switchgear thereof, in particular to a vertical lift-type high-safety dual-power supply device. Background technique [0002] In the known field of power distribution technology, the withdrawable mechanism has been widely used due to its characteristics of easy operation, convenient maintenance and replacement. The current technology mostly adopts a horizontal extraction mechanism, and the operator operates horizontally in front of the operator. In order to have sufficient horizontal depth to complete the extraction and push actions, the switch cabinet attachment requires longitudinal depth, especially in medium and high voltage switch cabinets. The extraction structure makes the longitudinal depth of the high-voltage switchgear larger and increases the volume of the cabinet. Moreover, the existing valve mechanism also faces problems such as large occupation volume an...

AI Technical Summary

Problems solved by technology

The current technology mostly adopts a horizontal extraction mechanism, and the operator operates horizontally in the front. In order to have sufficient horizontal depth to complete the extraction and push actions, the switch cabinet attachment requires longitudinal depth, especially in medium and high voltage switch cabinets. The withdrawable structure makes the longitudinal depth of the high-voltage switchgear larger and increases the volume of the cabinet

Moreover, the existing valve mechanism also faces problems such as large occupation volume and poor linkage.

At the same time, the existing busbars also have problems such as large overall volume and many connection points that easily cause heat, which further affects the insulation performance of insulating materials. At the same time, the integrity of various components, such as linkage valves and mechanical interlocks, is not good.
