Abstract
The utility model discloses a grounding switch and high voltage switch cabinet back door mechanical interlock device which comprises an interlock block, a sector plate, a compressed spring and a stop block. When a switch cabinet back door is closed, a right side wall of the interlock block presses against a round plate, the stop block is clamped in a groove, a right protruding block is inserted in a groove, and at this moment, the right protruding block presses the compressed spring. When the switch cabinet back door is opened, the groove is rotated out by the stop block, the compressed spring stretches to push the right protruding block out, and the left protruding block is inserted in the groove at this moment. According to the device, a pure mechanical scheme is employed, each interlock piece completely satisfies mechanical installation and operation, in a power cut operation of a switch cabinet, the switch cabinet back door only can be opened when a grounding switch is at a switch-on position, and in a power transmission operation, the grounding switch can not be operated when the switch cabinet back door is not closed.
Description
Technical field
The utility model relates to a kind of mechanical interlocks.
Background technology
In order to guarantee switch cubicle operation reliably and operator's safety, switch cubicle equipment is equipped with mechanical interlocks, and mechanical interlocks is enforceable, dependable performance.The interlocking at earthed switch in the past and switch cubicle back door, design defect mainly show when switch cubicle send the electricity operation, still can not divide the ground connection switch under the situation of closing back door.That is to say, if the user in the process of switch cubicle being sent electricity, closes the switch cubicle back door and removes the operational grounding switch in case forgotten, because violation operation can not be subjected to enforceable restriction, will cause the security incident of thinking at any time so.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides mechanical door interlock behind a kind of novel grounded switch and the high-tension switch cabinet, and its technical scheme of taking is:
Comprise interlocking segment, fanning strip, stage clip and stop block, interlocking segment is fixed on the madial wall at switch cubicle back door, and the diapire of interlocking segment upwards has groove
, the right side wall of stop block has groove left
, the left side wall of earthed switch operating axis has groove to the right
, stage clip is located at groove
Interior right side, the mid portion of fanning strip is fan-shaped block, the left end of fanning strip is the left projection of projection left, its right-hand member is the right projection of projection to the right, the position that is positioned at fan-shaped block right side on the fanning strip is plectane, and the diameter of plectane is greater than the diameter of fan-shaped block, when the switch cubicle back door is in closed condition, the right side wall roof pressure plectane of interlocking segment, block is stuck in groove
In, right projection is inserted in groove
In, this moment right projection compression press spring, when the switch cubicle back door was in open mode, block produced groove
, stage clip is upheld and is released right projection, and this moment, left projection was inserted in groove
In.
This device is taked pure mechanical conceptual, and each locking part satisfies machinery fully to be installed and operation, and when switch cubicle had a power failure operation, earthed switch only just can be opened the switch cubicle back door at closing position, when sending the electricity operation, be not related to close the switch cubicle back door can not the operational grounding switch.
Description of drawings
Fig. 1 is the structural representation of the utility model when the switch cubicle back door is in closed condition;
Fig. 2 is the structural representation of the utility model when the switch cubicle back door is in open mode.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As depicted in figs. 1 and 2, interlocking segment 1 is fixed on the madial wall at switch cubicle back door 6, and the diapire of interlocking segment 1 upwards has groove
7, the right side wall of stop block 5 has groove left
8, the left side wall of earthed switch operating axis 4 has groove to the right
9, stage clip 3 is located at groove
Right side in 9, the mid portion of fanning strip is fan-shaped block 2, and the left end of fanning strip is the left projection 10 of projection left, and its right-hand member is the right projection 11 of projection to the right, the position that is positioned at fan-shaped block 2 right sides on the fanning strip is plectane 12, and the diameter of plectane 12 is greater than the diameter of fan-shaped block 2.
When switch cubicle back door 6 is in closed condition, the plectane 12 that interlocking segment 1 promotes on the fanning strip makes right projection 11 enter into the groove of earthed switch operating axis 4
In 9, right projection 11 promotes stage clip 3, makes stage clip 3 be in compressive state.The left projection 10 of fanning strip breaks away from the groove of stop blocks 5 at this moment
8, the block 2 of fanning strip is stuck in the groove of interlocking segment 1
In 7, switch cubicle back door 6 can't be opened, and fanning strip can be unrestricted along with 4 rotations of earthed switch operating axis.
When fanning strip can turn to the earthed switch closing position along with earthed switch operating axis 4, block 2 broke away from the groove of interlocking segment 1
7, switch cubicle back door 6 can be opened.This moment, stage clip 3 returned to free stretched condition from compressive state, and promoted the groove of the left projection 10 insertion stop blocks 5 of fanning strip
In 8, stop block 5 is fixed on the cabinet and can not rotates, and has realized being not related to closing the switch cubicle back door, interlocking that can not the operational grounding switch.
