Technical field
The present invention relates to a kind of high-voltage switch cabinet grounding switch back door interlocking devices, are applied particularly to power transmission and distribution industry
High-tension switch cabinet manufacture mounting technique field.
Background technology
It is high-tension switch cabinet rear cable indoor location cable incoming-outgoing cable architecture of the prior art, current transformer, lightning-arrest
The key electric elements such as device when overhauling cable chamber components, need to operate the earthing switch in cabinet
To earthing position, do not allow to open to ensure the safety of maintenance process, i.e., when earthing switch is not in earthing position back door into
Row maintenance, on the other hand does not allow to operate earthing switch when not overhauling completion and closing back door, to ensure maintenance people
The safety of member.Above-mentioned regulation usually requires the interlocking mechanism at setting earthing switch and back door to ensure, existing mechanism is most
It is inconvenient there is complicated, the defects of Interlock Reliability is poor, higher safety operation requirement can not be met.
Invention content
It is easy to operate the technical problem to be solved by the invention is to provide a kind of simple in structure, it interlocks reliable height and presses off
Close cabinet earthing switch back door interlocking device.
The high-voltage switch cabinet grounding switch back door interlocking device of the present invention, including what is be fixedly connected with back door of high-tension switch cubicle
Push plate is installed on the connection that earthing switch operation boom end can be simultaneously moved forward and backward along the limit hole on back door of high-tension switch cubicle column
Closing piece, it is characterised in that：The earthing switch operating lever end set has the elastic cylindrical pin for being capable of operational grounding switch folding,
Interlocking segment is provided with the limiting groove coordinated with elastic cylindrical pin, the interlocking segment and the earthing switch operating lever active section shaft shoulder it
Between be provided with compressed spring；Push plate can push interlocking segment to move backward to expose elastic cylinder along the limit hole on rear door pillar
Pin pushes interlocking segment to block elastic cylindrical pin by limiting groove by the elastic-restoring force of compressed spring；
The push plate is also equipped with the rectangular slot closed with elastic cylindrical pin matching size；
The interlocking segment is rectangle, and the limit hole on rear door pillar is similarly rectangle；
The push plate rectangular slot width dimensions are less than interlocking segment width dimensions.
The high-voltage switch cabinet grounding switch back door interlocking device of the present invention, simple in structure, easy to operate, interlocking is reliable.
Description of the drawings
Fig. 1 is the high-voltage switch cabinet grounding switch back door interlocking device dimensional structure diagram of the embodiment of the present invention.
Specific embodiment
As shown in the figure, a kind of high-voltage switch cabinet grounding switch back door interlocking device, including being fixed with back door of high-tension switch cubicle
The push plate 1 of connection, being installed on 5 end of earthing switch operating lever simultaneously can be along before the limit hole on back door of high-tension switch cubicle column 3
The interlocking segment 4 moved afterwards, the flexible straight pin 2 of 5 end set of earthing switch operating lever；Interlocking segment 4 is provided with and elastic cylinder
2 matched limiting groove of pin；Compressed spring is provided between interlocking segment and the earthing switch operating lever active section shaft shoulder；Push plate 1
Interlocking segment 4 can be pushed to be moved backward along the limit hole on rear door pillar 3 to expose elastic cylindrical pin 2 or by compressed spring 6
Elastic-restoring force push interlocking segment 4 elastic cylindrical pin 2 is blocked by limiting groove；Push plate 1 is also equipped with and elastic cylindrical pin 2
The rectangular slot that matching size closes；Interlocking segment 4 is rectangle, and the limit hole on rear door pillar 3 is similarly rectangle.
The high-voltage switch cabinet grounding switch back door interlocking device of the present invention, it is particularly applicable to the high pressures with single open-type back door
Switchgear, is installed with " several " font push plate 1 on back door, and 5 end of earth operating lever is cylinder, in earth operating lever 5 according to
Secondary suit compressed spring 6, interlocking segment 4, interlocking segment 4 are limited by the shaft shoulder of compressed spring 6 and 5 active section of earth operating lever；Ground connection
Limit hole after 5 end of operating lever is stretched out on door pillar 3, compressed spring 6 are limited by rear door pillar 3 with interlocking segment 4；Interlocking segment 4
It can be slided along earth operating lever 5；Elastic cylindrical pin 2 is installed in operating lever end, when earthing switch is closed and opens, elastic cylinder
Pin can be rotated with earth operating lever；Interlocking segment 4 is rectangular block, and door pillar 3 opens up general with interlocking segment shape after cabinet
The square hole of size so as to the disengaging of interlocking segment 3, while limits interlocking segment 4 and rotates, and interlocking is reliable；Rectangular slot in push plate 1 with
The maximum appearance and size of elastic cylindrical pin 2 is adapted.
When earthing switch is in closing position, since 1 rectangular slot width dimensions of push plate are less than 4 width dimensions of interlocking segment,
Push plate 1 afterwards resists interlocking segment 4, and interlocking segment 4 cannot stretch the limit hole on door pillar 3 after protrusion；1 rectangle of push plate on back door
Slot is consistent with the direction of elastic cylindrical pin 2, and elastic cylindrical pin 2 exposes the limiting groove of interlocking segment 4 and stretches out 1 rectangular slot of push plate
Outside, back door can open, and carry out overhaul of the equipments；After back door is opened, interlocking segment 4 loses the pressure of back door fixed seat 1, compresses bullet
Outside limit hole after the elastic-restoring force promotion interlocking segment 4 of spring pops up on door pillar 3 so that elastic cylindrical pin 2 is caught in interlocking segment 4
On limiting groove in, limit hole on rear door pillar 3 limits so that interlocking segment 4 is from rotating, the limiting groove on interlocking segment 4
Limiting and stucking elastic cylindrical pin prevents earthing switch from operating；Maintenance, which finishes, shuts back door, and push plate 1 pushes interlocking segment 4 to retract
To rear door pillar limit hole；The limitation that elastic cylindrical pin 2 is detached from interlocking segment 4 is exposed, while stretches out the rectangular slot of push plate 1
Outside, earthing switch operating lever 5 can carry out sub-switching operation to earthing switch, and elastic cylindrical pin 2 is rotated with earthing switch operating lever 5
Plumbness is presented in rectangular slot on 90 ° to 100 °, with push plate 1, and back door cannot open, and safety coefficient is high, pushes interlocking segment 4
6 compressed energy-storage of compressed spring is pushed simultaneously, is closed a floodgate for earthing switch next time, back door maintenance electric elements is opened and prepares.
The high-voltage switch cabinet grounding switch back door interlocking device of the present invention, simple in structure, easy to operate, interlocking is reliable.
