Abstract
The utility model relates to an in, high tension switchgear's grounding switch blade's interlock. Including setting up the ground connection hole on the cubical switchboard shell, install a mechanical lock on the cubical switchboard shell of ground connection hole one side, a stopper is installed to the outer end of the spring bolt of mechanical lock, can drive the spring bolt and stretch out and draw back, and then make the stopper extend or recess the front side in ground connection hole through the key of rotary machine lock. Installation machinery lock on the cubical switchboard shell of ground connection hole one side to and at spring bolt outer end installation stopper, as long as rotate the key, can block the ground connection hole, prevent misuse.
Description
Technical field
The utility model relates to a kind of earthing switch blade interlock of middle high-pressure switch cubicle.
Background technology
The earthing switch blade of middle high-pressure switch cubicle of the prior art stretches out from ground hole, is exposed on the external, and manually operation makes earthing switch blade divide, closes.Because earthing switch blade does not arrange interlock, there is security incident in easy misoperation.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of earthing switch blade interlock preventing grounding misoperation plug-in strip.
The interlock of a kind of earthing switch blade of the present utility model, comprises the ground hole be arranged on switch board housing; The switch board housing of described ground hole side is provided with a mechanical lock, the outer end of the dead bolt of described mechanical lock is provided with a guide vane end stop; The key can locked by rotary machine, drives dead bolt to stretch, and then guide vane end stop is extended or recesses the front side of ground hole.
The switch board housing of ground hole side installs mechanical lock, and at dead bolt outer end mounting limit block, as long as rotate key, can ground hole be blocked, prevent misoperation.
The lateral surface of described guide vane end stop be indent, arc surface.Described confined planes can reduce the movement travel of guide vane end stop.After guide vane end stop recesses the front side of ground hole, its arc surface can play the guiding role to the functional unit of ground hole.
