Abstract
The invention provides an interlocking structure and a drawer cabinet provided with the interlocking structure. The interlocking structure comprises a first travel switch and a first triggering structure, wherein the first travel switch is provided with a first control button; the first triggering structure is used for triggering a first triggering part of the first control button; the first triggering part can move along with the entrance-exit arrangement action of a drawer on a drawer frame; when the drawer is not arranged in place on the drawer frame, the first triggering part moves to a position which is not in contact with the first control button, and the first travel switch controls a circuit breaker to be in a switch-off state; when the drawer is arranged in place on the drawer frame, the first triggering part moves to a position which is in contact with the first control button, the first control button is triggered, and the first travel switch controls the circuit breaker to be in a normal switch-on/off state. By adopting the interlocking structure and the drawer cabinet, the circuit breaker can only be started normally after the drawer is completely arranged in place, so that a copper bar is prevented from being burned out easily, and higher safety is achieved.
Description
Technical field
The present invention relates to switch cubicle technical field, be specifically related to a kind of interlock and there is the drawout cubicle of this interlock.
Background technology
Drawout cubicle generally adopts steel plate to make closure, and the electric elements with line are arranged in the drawer that can extract out, forms can complete a certain class and to power the functional unit of task.Drawout cubicle has higher reliability, fail safe and interchangeability, is more advanced switch cubicle, and the switch cubicle produced at present, majority is drawout cubicle.
Drawout cubicle of the prior art comprises drawer frame and pluggable the drawer be arranged on drawer frame, drawer is generally all provided with and meets electrolytic copper row, drawer frame is also provided with and meets electrolytic copper row, when drawer insertion is installed on drawer frame, the electrolytic copper row that connects on drawer arrange connect with the electrolytic copper that connects on drawer frame, thus is that electric component in drawer is powered.In order to when the electric elements controlling to be arranged on drawer start, people generally can install at drawer the circuit breaker being used for control apparatus element, drawer is installed to after on drawer frame, by controlling the break-make of circuit breaker, and then whether the electric elements controlling to be positioned at drawer start work.
But, when being installed on drawer frame by drawer, there is the situation that drawer is not in place safely, although now on drawer meet electrolytic copper row and the electrolytic copper that connects on drawer frame is arranged and is contacted, but this contact belongs to incomplete contact, contact area is less, and when operating breaker makes circuit ON, electric elements also can work, but it is little owing to connecing the contact area that electrolytic copper ranking puts, in big current or long use, this contact position can produce high temperature, causes easily burning out copper bar.
Summary of the invention
Therefore, the technical problem to be solved in the present invention is to overcome drawout cubicle of the prior art when drawer is not in place completely, the electrolytic copper row that connects be positioned on drawer arranges not exclusively contact with the electrolytic copper that connects be positioned on drawer frame, after circuit is connected in circuit breaker startup work, the technological deficiency that copper bar easily burns out, thus provide one only after drawer is in place completely, just enable circuit breaker start the interlock of work.

As illustrated in figs. 8-12, drawer 100 is being pushed gradually in the process of drawer frame 200, first guide post 22 slides gradually on the first guide edge 31, and driving the first trigger unit 21 be positioned on frizzen 2 close to the first travel switch 11 gradually, the sign 24 be located on frizzen 2 is switched by " separation " to " test " gradually;
When sign 24 is switched to " test " by " separation ", stop pushing inward drawer 100, now unclamp pressing lever 7, the second guide post 62 enters in test draw-in groove 34, can by spacing for drawer 100 in test position;
When needing drawer 100 to be in place completely, as shown in Figure 13-17 and Fig. 2-3, pressing pressing lever 7, second guide post 62 is deviate from test draw-in groove 34, continue to push inward drawer, first guide post 22 continues to slide on the first guide edge 31, second guide post 62 slides on the second guide edge 32, until when sign 24 switches to " connection " by " test ", stop pushing inward drawer 100, now unclamp pressing lever 7, the second guide post 62 enters and connects in draw-in groove 33, and now drawer 100 is spacing at link position.The first trigger unit 21 now on frizzen 2 contacts with the first control button 111 be located on the first travel switch 11, and triggers described first control button 111, the first travel switch 11 is controlled circuit breaker 300 is in can the state of normal divide-shut brake; The second trigger unit 61 in trigger member 6 contacts with the second control button 121 be located on the second travel switch 12, and triggers the second control button 121, the second travel switch 12 is controlled circuit breaker 300 is in can the state of normal divide-shut brake.
The course of action of the interlock that the present embodiment provides when being extracted out from drawer frame 200 by drawer 100 is as follows:
When needing drawer 100 outwards to extract out from drawer frame 200, first pressing lever 7 (needing bearing pin 72 and padlock 74 to remove before pressing) is pressed, pressing lever 7 promotes trigger member 6 and rotates, the second guide post 62 be arranged in trigger member 6 is produced in connection draw-in groove 33, and make the second trigger unit 62 be separated with the second control button 121 of the second travel switch 12 simultaneously, now the second travel switch 12 controls circuit breaker 300 and makes it be in gate-dividing state;
When using external force outwards to be extracted out from drawer frame 200 by drawer 100, continue the described pressing lever 7 of pressing, and outwards extract drawer 100 out gradually, first guide post 22 slides on the first guide edge 31, and drive the first trigger unit 21 to be separated with the first control button 111 of the first travel switch 11 gradually, first travel switch 11 controls circuit breaker 300 and is in gate-dividing state, and the sign 24 be arranged on frizzen 2 is switched to " separation " by " connection " gradually; Second guide post 62 moves on the second guide edge 32 of motion guide plate 3 gradually;
When drawer 100 detaches completely from drawer frame 200, the first guide post 22 slides with the first guide edge 31 and is separated, and the second guide post 62 slides with the second guide edge 32 and is separated.
It should be noted that, first travel switch 11 is electrically connected with the moment shunt opening coil being located at circuit breaker 300 inside, second travel switch 12 is electrically connected with the switching winding being located at circuit breaker 300 inside, when drawer 100 is outwards extracted out, first travel switch 11 controls rapidly circuit breaker 300 separating brake by moment shunt opening coil, ensures safety; When people encounter unintentionally pressing lever 7, even if contact again after causing the second control button 121 to separate instantaneously with the second trigger unit 61, now switching winding can not control circuit breaker 300 separating brake, can ensure the normal operation of equipment.
