Abstract
The invention relates to a linkage command device of a safety isolating device of an isolating valve of a drawout breaker. A drawing plate is provided with a shifting sheet; the shifting sheet can rotate around a shaft; the front end of the shifting sheet is a straight sheet with an inclined plane, and the rear part of the shifting sheet is provided with a cam surface and a horizontal plane; the side surface of a chassis is provided with a slide block; the lower part of the slide block is provided with a pin roller; the lower part of the a breaker body abuts with the horizontal plane of the shifting sheet; the breaker is pressed on the horizontal plane of the drawing plate after being put on the drawing plate and meanwhile blocks the shifting sheet rotating anticlockwise around the shaft on the drawing plate. With the push of the drawing plate, the pin roller fixed on the slide block gradually approaches to the shifting sheet until touching the inclined plane, and immediately, the pin roller slides to the horizontal plane along the inclined plane and stops when the slide block moves upwards. When the breaker is put on a drawing frame, the bottom of the drawing frame acts on the cam end of the shifting sheet to enable the shifting sheet to rotate anticlockwise around the shaft; and the shifting sheet rotates anticlockwise around the shaft after the breaker is moved out of the drawing frame until the shifting sheet is blocked by the stopping surface of the drawing plate.
Description
Technical field
The present invention relates to taking out in the frame for the isolating door safety guard that prevents from shocking by electricity of a kind of drawout breaker.
Background technology
Existing a kind of device is to move back and forth the actuating safety screen by the slide plate of taking out drive circuit breaker movement in taking out frame on the frame to open or close.Safety screen is opened the circuit breaker bus is entered, by connector with take out the frame bus and be electrically connected.Circuit breaker is after take out frame and shift out, and safety screen is closed to make and taken out bus charged on the frame and connector and external isolation.This device defect be when circuit breaker shift out take out frame after, operation is taken out frame slide plate travel mechanism and slide plate is moved back and forth also can open or close by the actuating safety screen, or directly acts on safety screen and also can open safety screen.So just can not satisfy circuit breaker shifts out and takes out the requirement that can not open safety screen behind the frame.
Then adopt by circuit breaker and promote the device that a guide rod actuating safety screen is opened, circuit breaker shifts out to be taken out behind the frame operation and takes out frame slide plate travel mechanism and slide plate is not moved back and forth can open by the actuating safety screen.This device shifts out and takes out the requirement that can not open safety screen behind the frame in order to satisfy circuit breaker, has added the device that a cover locked secure baffle plate is opened.Shift out at circuit breaker like this and must carry out at once the operation of locked secure baffle plate after taking out frame, if otherwise touch the guide rod that the actuating safety screen is opened, safety screen just can be opened, or circuit breaker put into take out the lock operation that will remove safety screen before the frame, otherwise operation running circuit breaker operating mechanism makes circuit breaker movement in taking out frame will damage associated components.
Summary of the invention
Based on the problems referred to above, a kind of isolating door safety insulating device of drawout breaker and the isolating door safety guard of linkage self-locking device, interlock command device composition are provided, the present invention is the interlock command device of isolating door safety insulating device wherein.
For achieving the above object, the present invention is achieved through the following technical solutions:
The interlock command device of device of drawout breaker isolating door safe isolating, comprise breaker body, pumping board and underframe, at pumping board one plectrum is installed, described plectrum can rotate around the axis, the front end of plectrum is the bevelled straight sheet of a tool, and the rear portion has cam surface and horizontal plane; A slide block that moves up and down is installed in side at underframe, and load parts are installed in the bottom of slide block, and the load parts contact with the inclined-plane of plectrum; The bottom of breaker body and the horizontal plane of described plectrum offset.
Described load parts are one to have the strutting piece of bearing position, can be circular or square post piece, perhaps preferably adopt a roller.
Front end at pumping board is provided with a stop surface, and described stop surface is positioned at the below of the straight sheet in plectrum top, is used for the angle that the restriction plectrum reverses downwards.
Be pressed on the horizontal plane of plectrum after circuit breaker is placed on and takes out on the frame, stop that simultaneously plectrum rotates counterclockwise around the axle on the pumping board.Along with pumping board advances, be fixed in the asymptotic plectrum of roller on the slide block until touch the inclined-plane, slide into horizontal plane along the inclined-plane immediately, slide block moves up and stops.
Circuit breaker is put when taking out frame, and the cam end that the bottom surface that circuit breaker is taken out frame acts on plectrum makes plectrum rotate counterclockwise around the axle on the pumping board; Plectrum rotated counterclockwise around the axle on the pumping board after circuit breaker shifted out and takes out frame, until plectrum is hampered by the stop surface of pumping board.Advance pumping board, plectrum and roller are not collided and are made slide block keep static.
