Description
One, technical field
The utility model relates to switch cubicle incorrect operation preventing interlocking apparatus in the power supply unit, specifically, is the incorrect operation preventing interlocking apparatus of drawer-type switch cabinet, refers in particular to the incorrect operation preventing interlocking apparatus that is exclusively used in the GEAPLUS2.OMCC drawer-type switch cabinet.
Two, background technology
GEAPLUS 2.OMCC switch cubicle is the switch cubicle of import, and in its drawout cubicle, but current supply circuit is mainly by bus independent separate or the inlet wire plug that patches, circuit breaker, constitute with the synchronization-moving outlet plug of drawer, output socket.When the power supply drawer unit is in service position, breaker closing operation, if there is not interlock, be easy to cause the charged source of inlet wire plug to separate such misoperation, cause that arc short-circuit has a power failure, and damages the bus of inlet wire plug and grafting thereof.Therefore, be necessary regulation, corresponding anti-misoperation apparatus is set according to the electric equipment safety standard.
At present, the GEAPLUS 2.OMCC drawer-type switch cabinet on the market prevents that the technical scheme that accident takes place from being mostly: in case when the misoperation of inlet wire plug takes place, with utilizing mild steel rope thimble to touch the release button of circuit breaker, make circuit breaker trip.This is a kind of remedial after misoperation occurring, though the accident that can prevent takes place, can not prevent the generation of misoperation; In addition, this technical scheme is cost with the power failure, can influence normal production operation and causes damage.
Three, summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of interlock of the drawer unit misoperation that can prevent to power is provided for the GEAPLUS2.OMCC drawer-type switch cabinet.
For realizing above purpose, the technical scheme that the utility model is taked is:
The incorrect operation preventing interlocking apparatus of drawer-type switch cabinet contains interlocked control handle (that is, the action bars of circuit breaker operation mechanism), it is characterized in that, comprises the interlocking connecting lever, hangs pin, lock pin, lock pin support, inlet wire plug handle hole and lockpin hole; The upper end of interlocking connecting lever is set with the interlocked control handle, and the interlocking connecting lever forms a fixed angle that becomes 45 degree each other with the interlocked control handle; The lower end of interlocking connecting lever is connected with the end of lock pin by hanging pin; Be provided with the lock pin support in the centre position of lock pin, the endoporus that lock pin passes on the lock pin support moves back and forth on the lock pin support; In the position on lock pin top, promptly the side of main inlet wire plug handle hole is provided with a lockpin hole, the size of lockpin hole should be enough to lock pin is passed; When the inlet wire plug was in complete plug-in position, the top of lock pin just was locked in the inlet wire plug handle hole by lockpin hole.
Described lock pin is " L " shape structure, and the lock pin of " L " shape is terminal to be connected with the interlocking connecting lever by hanging pin, and the lock pin top of pin shape is by lockpin hole turnover inlet wire plug handle hole.
The lock pin support that is provided with in the centre position of lock pin has the hole for falling the structure of saddle in the projection on the structure of falling saddle both sides, lock pin is worn and led in the hole.
During operation, clockwise rotate the interlocked control handle of drawer-type switch cabinet, the interlocked control handle will drive the interlocking connecting lever and rotate, the interlocking connecting lever drives lock pin and moves to inlet wire plug handle hole direction, up to lockpin ventilating being crossed lockpin hole insertion inlet wire plug handle hole and inlet wire plug handle hole being pinned fully, this moment, the action bars of circuit breaker operation mechanism was in the position of closing a floodgate fully.If separate the inlet wire plug, then rotate counterclockwise the interlocked control handle of drawer-type switch cabinet, the interlocking connecting lever drives lock pin and moves to the direction that deviates from inlet wire plug handle hole, after lockpin ventilating is crossed lockpin hole and is withdrawed from from inlet wire plug handle hole fully, circuit breaker, operating mechanism, action bars are in gate-dividing state completely, and can separate the inlet wire plug this moment.When circuit breaker during in the separating brake position, if the inlet wire plug is pegged graft not in place or not at plug-in position, lock pin just can't insert inlet wire plug handle hole, gets back to closing position with regard to the action bars that has stoped circuit breaker operation mechanism like this.
The utility model has remedied the deficiency of existing GEAPLUS 2.OMCC drawer-type switch cabinet incorrect operation preventing interlocking apparatus, the power interlock of drawer unit misoperation of preventing of being provided has successfully avoided the inlet wire plug to divide in the operating mistake of breaker closing, and when the misoperation of inlet wire plug breaker closing during not at plug-in position, have knot and simple, function advantage complete, easy to use, the generation of the event that prevented from effectively to make trouble.
Four, description of drawings
Lock pin withdrawed from the structural representation of plug-in position when Fig. 1 was the utility model breaker open operation position;
Lock pin dropped into the structural representation of plug-in position when Fig. 2 was the utility model breaker closing position.
Label among the figure is respectively:
01, interlocked control handle, 1, the interlocking connecting lever, 2, hang pin, 3, lock pin, 4, the lock pin support, 5, inlet wire plug handle hole, 6, lockpin hole.
Five, embodiment
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
The incorrect operation preventing interlocking apparatus of the utility model drawer-type switch cabinet comprises interlocked control handle (action bars of circuit breaker operation mechanism) 01, interlocking connecting lever 1, hangs pin 2, lock pin 3, lock pin support 4, inlet wire plug handle hole 5.
When the inlet wire plug when patching the position fully, clockwise rotate the interlocked control handle 01 of drawer-type switch cabinet, interlocked control handle 01 drives interlocking connecting lever 1 and rotates, interlocking connecting lever 1 drives lock pin 3 and is moved to the left, inlet wire plug handle hole 5 is pinned fully by lockpin hole 6 up to lock pin 3, the inlet wire plug can't be separated, and this moment, the interlocked control handle 01 of circuit breaker operation mechanism was in complete "on" position.
If separate the inlet wire plug, can rotate counterclockwise the interlocked control handle 01 of drawer-type switch cabinet, interlocking connecting lever 1 drives lock pin 3 and moves right, when lock pin 3 by lockpin hole 6 fully when inlet wire plug handle hole 5 withdraws from, circuit breaker, operating mechanism, interlocked control handle 01 etc. are in complete gate-dividing state, and can separate the inlet wire plug this moment.When circuit breaker is in the separating brake position,, so just stoped the interlocked control handle 01 of circuit breaker operation mechanism to get back to the position of combined floodgate because the inlet wire plug is pegged graft not in place or not at plug-in position, lock pin 3 can't enter inlet wire plug handle hole 5.
Incorrect operation preventing interlocking apparatus described in the utility model is the incorrect operation preventing interlocking apparatus of metal structure.
