Embodiment
Referring to Fig. 1-Fig. 3, the current transformer cabinet door of the present embodiment shares five parts composition, is respectively：Water cooling plant cabinet door, axis
One cabinet door, two cabinet door of axis, three cabinet door of axis and auxiliary cabinet door.Wherein：Water cooling plant cabinet door and one cabinet door of axis are opened to the left, one cabinet of axis
Door, two cabinet door of axis, three cabinet door of axis and auxiliary cabinet door are opened to the right.Each cabinet door is 180 ° rotatable, is in parallel shape with cabinet.Except water cooling
Device cabinet door is that have Yishanmen, other to be made of 2 fans, and two 180 ° of fan cabinet door folding rotaries, therefore switch convenience,
It is not take up space between machinery, facilitates cabinet maintenance and inspection.
The present invention with interlock function cabinet door be applied to the unsteady flow cabinet on, installation site such as Fig. 2 of interlock A and
Shown in Fig. 3, interlock A is mounted between two neighboring cabinet door.Interlock A installation site and amplification effect in cabinet
Figure is as shown in Figure 3.The cabinet is filled altogether there are four interlock, main to realize between cabinet door switch interlock in order.Each unsteady flow
Cabinet, door lock, the switch to unsteady flow cabinet door is realized by key equipped with one.
The course of work of the present invention is as follows：
Converter cabinet has multiple leaf door, and open and close sequence on the door has strict requirements, interlock that this work(can be realized
Energy：Be mounted on the cabinet vertical beam between left and right door by fastening bolt 8 and mounting bracket 9, must be installed on left and right door
On push plate (first to fourth push plate 10-13 is denoted as push plate a, push plate b, push plate c, push plate d) and is used cooperatively.According to door opening square
To difference, interlock can exchange 180 ° of installations up and down.
The first long threaded rod 4 of nut 1 and limiting plate 2 is installed on spring 3 while being acted and (is claimed component e), be installed on screens
Second long threaded rod 5 of plate 6 acts simultaneously with spring 3 (claims component f).
Illustrate the operation principle of interlock with figure below：
Component e clamshell doors serve interlocking.When door is closed, the 10 thrust assemblies e of the first push plate on right door
On the first long threaded rod 4 so that nut 1 is extend on left-hand door in the hole of third push plate 12 by the compression displacement of spring 3；In this way,
Right Men Ruo is not opened in advance, and when nut 1 cannot exit third 12 hole of push plate completely, the third push plate 12 of upper left is by component e
Limiting plate 2 blocks, and does not open.
Component f is to interlocking effect of having closed the door.When door is closed, on the 13 thrust assemblies f of the 4th push plate on left-hand door
The second long threaded rod 5, so that block board 6 on component f is moved right by the compression of spring 3, be the second push plate 11 on right door with
Right door rotation leaves enough spaces.At closing time, first the spring 3 on component f need to be enabled to move to right left-hand door closing and is shut off right door,
Otherwise the second push plate 11 on right door will be stopped by the block board 6 on component f and can not close.
By this interlock, the ingenious restriction for realizing open and close sequence on the door.
