Perpendicular lifting type high safety double-power-source power supply device and control method thereof

Abstract

The invention discloses a perpendicular lifting type high safety double-power-source power supply device. The device comprises a support provided with a vertical beam in the middle, a busbar integral insulating contact case fixedly arranged at one side of the top of the support, lifting mechanisms arranged at the two sides of the vertical beam of the support and a hand cart arranged on the support plate and borne with multiple side output linear poles and a translation drive type protection mechanism. According to the perpendicular lifting type high safety double-power-source power supply device, the front door plate and the rear door plate which homodromously move and is arranged in a front-rear spaced mode are adopted, and a front-rear stacking form is adopted, the design space of a movable door is effectively saved, the miniaturization of the drive mechanism is achieved, the structure is reasonable, the front door plate and the rear door plate are utilized through motion control over intermittent drive translation of the hand cart, overlapping or staggering corresponding to through holes is achieved, the safety is effectively guaranteed, the achievement is simple, and the motion is reliable.

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 and a control method. 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...

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. How to use the height space to realize the linkage and cooperation of various components has become an urgent problem to be solved.
