Dual power supply unit

Abstract

Disclosed is a high-secure and dual-power supply device. The high-secure and dual-power supply device comprises a support, an integrated insulation contact box which is steadily set up at a busbar at the top side of the support, several terminal posts in lateral outlet line type and an actuator which are set up on a supporting plate, a retractable and mobile valve of the high-voltage insulation, as well as a mechanical interlocking device. The actuator is set up at the lifting supporting plate for making full use of the height space and simplifying the action device. A front door plank and a rear door plank moving around are adopted and set up in interval. The front door plank and the rear door plank are stacked one after another for effectively saving the design space of the valve and realizing the miniaturization of a driving device and a reasonable structure. Controlling a motion of the intermittent handcart-driven translation of the front door plank and the rear door plank can realize corresponding overlap or stagger of the hole for effectively guaranteeing the security and implementing a concise and reliable motion.

Description

technical field [0001] The invention relates to the technical field of dual-power switching equipment and a switchgear thereof, in particular to a 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 and poor linkage. At the same ti...

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 in turn affects the insulation performance of insulating materials.
