The high-tension switch cabinet of the present invention is as follows with interlocking mechanism's specific operation process：
This interlocking mechanism is set to high-tension switch cabinet inner wall, and trigger mechanism 7 coordinates with front door of switch cabinet, connecting rod 4 and rear door of switch cabinet
Connection.Second spring 63 and 75 original state of third spring are in compressive state.When opening front door, front door of switch cabinet is lost
The limitation of mechanism, third spring 75 extend, on the one hand, drive 72 lower part of J-shaped oscillating rod to swing to the left, and then drive briquetting 73 to
Left movement presses down convex block 55, and then is moved downward with motion plate 53 so that the first block 56, which moves downward, closes at cavity 51
Interior, the first spring 57 elongation, pilot hole 54 play the guiding role, and transverse slat 53 is avoided to shift and lead to the first block 56 and convex block
55 cannot reset, and on the other hand, 72 top of J-shaped oscillating rod be driven to swing to the right.In this way, front gate of high-voltage switch cabinet is only opened,
Trigger mechanism 7 just operates, and position-limit mechanism 5 operates after triggering so that the first block 56 is withdrawn in cavity 51, loses the first block 56
After the blocking limit of sliding block 3, back door of high-tension switch cubicle can just be opened.Back door of high-tension switch cubicle leads to during opening
It crosses connecting rod 4 to slide to the left with movable slider 3, second spring 63 extends, and the second block 62 is driven to move right, and then drives telescopic rod
61 elongations, this process bracing wire 64 are constantly in tight state, in this way, after back door of high-tension switch cubicle is opened, the second block 62 is to the right
Movement plays restriction effect to front gate of high-voltage switch cabinet so that front gate of high-voltage switch cabinet can not close.Back door of high-tension switch cubicle closes
During closing, reset is slided to the right with movable slider 3 by connecting rod 4, drives the second block 62 to move downward reset by bracing wire 64,
63 retracted for clearance of second spring, 61 retracted for clearance of telescopic rod, only after back door of high-tension switch cubicle, which is closed, to be resetted, the second block 62
After reset, front gate of high-voltage switch cabinet can just close.After touching J-shaped oscillating rod 72 in front gate of high-voltage switch cabinet closing process,
It pushes 72 top of J-shaped oscillating rod to swing reset to the left, and then drives 72 lower rightward of J-shaped oscillating rod to swing and reset so that briquetting
73 move right reset, and convex block 55 loses the limitation of briquetting 73, and under the elastic force effect of the first spring 57, the first spring 57 drives
Transverse slat 53 moves upwards, and then the first block 56 and convex block 55 is driven to move upwards reset, and the first block 56 plays limit to sliding block 3
Effect so that sliding block 3 cannot move downward, so that rear door of switch cabinet can not be opened.Pass through the interlock safe and convenient
Realize the cabinet door opening sequence of high-tension switch cabinet in ground so that only front gate of high-voltage switch cabinet could open high-tension switch cabinet after opening
Back door, only close back door of high-tension switch cubicle could open front gate of high-voltage switch cabinet, caused by avoiding maloperation safety ask
Topic, and without other operations, it is simple and efficient, as long as the action of normal switch gate is coordinated to can be realized, using pure mechanic structure,
Under all structure members are at low cost, avoid some cost problems brought because using procedure lock, repair it is also very convenient,
The assembly spent time is few, greatlys save manpower and materials.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to the foregoing embodiments
Invention is explained in detail, it will be understood by those of ordinary skill in the art that；It still can be to aforementioned each implementation
Technical solution recorded in example is modified or equivalent replacement of some of the technical features；And these modification or
It replaces, the spirit and scope for various embodiments of the present invention technical solution that it does not separate the essence of the corresponding technical solution.
