Embodiment Construction

[0010] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0011] It can be seen from Fig. 1, Fig. 2A and Fig. 2B that the present invention includes: a grounding knife 1, an isolation door panel 2; Mechanism 3 includes: a movable ferrule 31 welded to the isolation door panel at one end, and a movable chuck 32 fixed to the main shaft of the grounding knife 1 at the other end; when the grounding knife 1 is electrified, the movable ferrule 31 will withstand the isolation door panel 2; When the grounding knife 1 is not charged, the movable ferrule 31 is separated from the isolation door panel 2;

[0012] In addition, when the isolation door panel is opened and in the maintenance position, the grounding knife cannot perform live operation; only when the isolation door panel is closed and closed can the power transmission operation be performed.

[0013] Therefore, if the door panel of the compartment can b...

Abstract

The invention relates to a high voltage switch cabinet that comprises: grounding knife(1), separating door-plate(2); it also includes machine compulsion device(3); said machine compulsion device(3) is between the grounding knife(1) and the separating door-plate(2); the machine compulsion device(3) includes: active cutting ferrule(31), one end of which is welded to the separating door-plate, active draw-in gear(32), the other end of which is fixed to the main axes of the grounding knife(1); when the grounding knife(1) charges, said active cutting ferrule(31) withstands the separating door-plate(2); when the grounding knife(1) does not charge, said active cutting ferrule(31) and the separating door-plate(2) are separated; The benefit effects of the invention are: only on condition that the electrification device is out of electricity, the little door of overhauling separating room can be opened to realize the operation of examine and repair, so safety of operating personnel can be guaranteed.

Description

technical field [0001] The invention relates to a high-voltage switch cabinet, in particular to an isolation door panel in the high-voltage switch cabinet. Background technique [0002] KYN61-40.5 high-voltage switchgear is a complete set of 40.5KV three-phase AC 50HZ power distribution device, which is mainly used for receiving and distributing electric energy in power plants, substations and power distribution rooms of industrial and mining enterprises, and can realize circuit control, protection, And detection, in addition to being widely used in general power systems, it can also be used in places with frequent operations. [0003] The existing KYN61 high-voltage switchgear, in the process of use, once the operator makes a mistake, it is easy to enter the live isolation during maintenance: that is, when the isolation door is opened, the live parts are still charged, which affects their own safety. Contents of the invention [0004] The technical problem to be solved b...
