Problems solved by technology

When the baffle type valve is closed, it does not completely cover the insulation creepage range of the main bus box. When the switch circuit is powered off for maintenance and the main bus is still charged, the staff may easily touch the insulating surface of the main bus box, and there is still a risk of electric shock. , there is a security risk

Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] like Figure 1-9 As shown, the present invention includes a bracket 1 with a vertical beam 11 in the middle, correspondingly arranged on both sides of the vertical beam of the bracket and a translation-driven protection mechanism correspondingly arranged on both sides of the vertical beam of the bracket. The mechanism is set in one-to-one correspondence with the translation-driven protective mechanism,

[0042] The lifting mechanism includes a supporting plate that is driven to lift vertically, two support arms arranged in a figure-eight shape hinged below the supporting plate, and a bottom rail that is matched with the lower end of the support arm and fixedly connected with t...

Abstract

The invention discloses a lifting linkage type valve device. The lifting linkage type valve device comprises a support, a lifting mechanism and a translational driving type protective mechanism, wherein a vertical beam is arranged at the middle part of the support, and the lifting mechanism and the translational driving type protective mechanism are correspondingly arranged on two sides of the vertical beam of the support; the translational driving type protective mechanism comprises a linkage pin, a sector gear and a rack; the linkage pin is fixedly arranged on one side of a supporting plate and extends horizontally; the sector gear is fixedly arranged on the support in a rotatable manner, and a guide groove matched with the linkage pin is formed in the sector gear; and the rack is connected with the sector gear in an engaged manner and is fixedly connected with an insulated valve. An executing mechanism is arranged on the liftable supporting plate, so that the height space is sufficiently utilized, and an actuating mechanism is simplified; and moreover, synchronous driving of a translational part to be driven is realized by using linkage of the lifting mechanism and the translational driving mechanism, so that the device is convenient in integral design, and the using safety is particularly improved.

Description

technical field [0001] The invention relates to the technical field of dual-power switching equipment and a switch cabinet thereof, in particular to a lifting linkage valve 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. [0003] Now, the space required for power supply is getting smaller and smaller, but the load ...
