Description
Technical field
The invention belongs to high-tension switch cabinet parts technical fields, interlock more specifically to a kind of high-tension switch cabinet is counter
Device.
Background technique
At present in electric system, the rear cabinet door interlocking of high-tension switch cabinet is mainly opened by rear cabinet door plate, baffle, side plate, ground connection
Big axis, locking plate composition are closed, rear cabinet door interlocking is main to switch big axis rotation rotation by operational grounding, big by earthing switch
The rotation of axis drives locking plate rotation, i.e., locking plate is turned inwardly toward horizontality by vertical state, when rear cabinet door plate is closed, rotation
The locking plate turned clamps just to be transferred between baffle and rear cabinet door plate, thus realizes the purpose of interlocking rear cabinet door plate.It is such
Structure, although rear cabinet door interlocking can be realized earthing switch and be under gate-dividing state, rear cabinet door plate cannot be opened, in rear cabinet
In the case that door-plate is not turned off, earthing switch still can carry out breaking-closing operating, not meet anti-interlock demand, Wu Fafang
Only maloperation, there are severe compromises.
Summary of the invention
The purpose of the present invention is to provide a kind of anti-interlocks of high-tension switch cabinet, and structure is simple, easy for installation, Neng Gouke
It is interlocked by realizing that rear cabinet door plate is counter, only closing rear cabinet door could carry out sub-switching operation to earthing switch, prevent maloperation, effectively
It prevents because of maloperation bring security risk.
A kind of anti-interlock of high-tension switch cabinet of technical solution of the present invention, including high-tension switch cabinet and interlock, high pressure
Switchgear includes rear cabinet door, and the interlock includes locking plate and the earthing switch big axis fixed with locking plate, described
Locking plate is arranged towards rear cabinet door, and the big axis of earthing switch and locking plate are fixed far from the side of rear cabinet door, the anti-interlock packet
The horizontal slide being mounted at the top of high-tension switch cabinet, horizontal slide and locking plate right angle setting are included, is provided in horizontal slide perpendicular
Straight slide bar and reset spring, the reset spring are horizontally set on the end of upright sliding bar and horizontal slide far from rear cabinet door, institute
It states upright sliding bar bottom and is provided with horizontal lever, the horizontal lever setting is described in locking plate side and vertical with locking plate
It is provided with push rod at the top of rear cabinet door medial surface, the push rod is horizontally disposed and towards upright sliding bar.
Preferably, the push rod includes fixed part and rotating part, and the fixed part is fixedly connected with rear cabinet door, institute
It states rotating part and rear cabinet door end is provided with V-type fork, V-type fork can realize 90 degree of rotations, and push rod is arranged in locking plate
Upper position.
Preferably, distance is greater than horizontal slide close to rear cabinet door end between oral area and rear cabinet door in the V-type fork of the push rod
Horizontal distance between locking plate.
Preferably, between distance is greater than at the top of locking plate horizontal slide between the horizontal lever and horizontal slide it is vertical away from
From.
Preferably, the horizontal lever length is greater than distance between locking plate and rear cabinet door.
Preferably, the horizontal slide length is greater than push rod length.
A kind of anti-interlock of high-tension switch cabinet of technical solution of the present invention, during rear cabinet door is opened, push rod is with rear cabinet
Door withdraws high-tension switch cabinet, and vertical push rod resets under the action of reset spring, and locking plate is blocked in horizontal lever reset, so that connection
Locking plate is not able to rotate, and realizes anti-interlocking；When rear cabinet door is closed, push rod enters high-tension switch cabinet and pushes upright sliding bar, vertically
Slide bar drives horizontal lever to move forward, and horizontal lever is pushed away from from locking plate side, horizontal lever is avoided to block locking plate,
Locking plate can be freely rotated at this time, realize interlocking.
The beneficial effect of technical solution of the present invention is:
A kind of anti-interlock of high-tension switch cabinet of technical solution of the present invention can reliably realize that rear cabinet door plate is counter and interlock, only
Sub-switching operation could be carried out to earthing switch by closing rear cabinet door, prevented maloperation, effectively prevent because maloperation bring is hidden safely
Suffer from.
