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 and improve grounding safety has become an urgent need to be solved. question

Abstract

The invention discloses a vertical lift type high-safety dual-power supply apparatus. The vertical lift type high-safety dual-power supply apparatus comprises a bracket with a vertical beam in the middle part, a busbar integrated type insulating contact box arranged on one side of the top of the bracket, lifting mechanisms arranged on the two sides of the vertical beam of the bracket, a handcart which is arranged on a supporting plate and bears multiple side wire outlet type pole columns, and a translational driving type protective mechanism. A front door plate and a back door plate which move in the same direction and are arranged at intervals front and back are adopted in a front and back stacking way, so that the design space of movable doors can be effectively saved, and miniaturization of the driving mechanism and reasonable structure are realized; by virtue of interval driving translational action control of the front door plate and the back door plate through the handcart, corresponding overlapping or staggering of through holes are realized, and safety is ensured effectively; and meanwhile, simple realization and reliable actions are achieved.

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...
