Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art exactly, it is provided that a kind of easy to operate, protected effect good, avoids the rotary-type switch cabinet handcart handle hole error-proof device of maloperation.
For reaching above-mentioned purpose, this utility model is reached by following measure:
A kind of rotary-type switch cabinet handcart handle hole error-proof device, including switch cubicle, before switch cubicle, cabinet face is provided with handcart handle hole, before it is characterized in that switch cubicle, cabinet face is provided with the annular base of band circular cover, the handcart handle hole enclosure is in annular base, the lower end of cover plate and annular base is hinged through the alignment pin being perpendicular to cover plate, the upper end of cover plate and annular base is respectively equipped with the connection lug being involutory, connection lug is perpendicular with front cabinet face and is provided with lockhole, cover plate is connected with annular base locking by padlock through lockhole
The end face of annular base described in the utility model is provided with connecting hole, and annular base is connected with front cabinet face by bolt through connecting hole.
Front cabinet face described in the utility model is provided with audible-visual annunciator, audible-visual annunciator switch is provided with insulating disc, annular determines contact block, circular movable contact spring, spring and briquetting, annular is determined contact block and is pasted onto on insulating disc edge, spring one end is connected with insulating disc bottom surface central authorities, the other end is connected with circular movable contact spring center, the upper surface of circular movable contact spring is connected with briquetting, insulating disc bottom surface is pasted onto on the connection lug of annular base, under the action of the spring, circular movable contact spring acts against annular and determines on contact block, alarm is in connection alarm condition, when circular cover is buckled on annular base, when circular cover is in locking guard mode, circular cover makes briquetting move down, make circular movable contact spring be in disengaging annular and determine contact block state, cut off audible-visual annunciator power supply, audible-visual annunciator is not reported to the police.
nullThis utility model is in operation maintenance personnel、When maintainer investigates the potential safety hazard of high-tension switch cabinet，Open padlock and rotate circular cover，The switch cabinet handcart handle hole in annular base is made to expose，Again with making switch cubicle be displaced to operating position，Then go back to circular cover and locked by padlock，To work contentedly，Open padlock again when work is complete and rotates circular cover，Expose switch cabinet handcart handle hole，After making switch cubicle position reset by handle，Switch cabinet handcart handle hole is sealed and locks circular cover by cycle circular cover again，Maloperation is prevented with protection switch cabinet handcart handle hole，When circular cover separates with annular base，Circular movable contact spring acts against annular under the action of the spring to be determined on contact block，Alarm is in connection alarm condition，To remind this high-tension switch cabinet of staff to be in off working state，There is safety good、Reliable operation、The advantage such as easy to operate，It is particularly well-suited to the single inspection operation to switch cubicle.
