The invention discloses a kind of earthing switches and the anti-interlock in back door, it is characterized by comprising mandrils, mandril is equipped with the interlocking fixed plate being connected on cabinet door frame, one end of the mandril, which is equipped with, is located at the big axis on same axis direction with it, and when back door closing, the mandril was towards the big axis direction moving contact；Interlocking fixed plate on the mandril includes the first interlocking fixed plate and the second interlocking fixed plate, and the second interlocking fixed plate is equipped with the second locking pressure spring for supporting the mandril to be detached from the big axis.This earthing switch of the present invention and the anti-interlock in back door, structure is simple, and realization back door that can be stable is counter to be interlocked, and has stronger practicability and preferable application prospect.
Description
Technical field
The invention belongs to high-low pressure technical field of electricity, more specifically to a kind of earthing switch with back door is counter interlocks
Device.
Background technique
The substation of most area, power distribution room construction area are all more abundant at present, for consider project installation, maintenance and
Middle-placed switch cabinet is usually designed to mode not mounted against a wall by the convenience of maintenance.Back door is changed to two sides hinged door form, and realization is facilitated to open
Close the two-sided maintenance in front and back of cabinet.The back door of middle-placed switch cabinet interlocking is realized by earthing switch operating mechanism interlock.But work as back door
After opening, it direct operational grounding can still switch to separating brake in not closing back door, to release the interlocking of breaker, break
Road device can carry out closing operation, and because back door is not turned off, cable vault's electrification is easy to lead to personal safety accident.
Summary of the invention
Present invention aim to address problem of the existing technology, provide that a kind of structure is simple, after realization that can be stable
The anti-earthing switch interlocked of door and the anti-interlock in back door.
To achieve the goals above, the technical scheme adopted by the invention is as follows: provided this earthing switch and back door are anti-
Interlock, it is characterised in that: including mandril, mandril is equipped with the interlocking fixed plate being connected on cabinet door frame, the mandril
One end be equipped with and be located at the big axis on same axis direction with it, back door when closing the mandril moved towards the big axis direction
Contact；Interlocking fixed plate on the mandril includes the first interlocking fixed plate and the second interlocking fixed plate, and second interlocking is solid
Fixed board is equipped with the second locking pressure spring for supporting the mandril to be detached from the big axis.
To keep above-mentioned technical proposal more detailed and specific, the present invention also provides optimization technique sides further below
Case, to obtain satisfied practical function:
The big axis is equipped with the third interlocking fixed plate being connected on the cabinet door frame.
The first interlocking fixed plate, the second interlocking fixed plate and third interlocking fixed plate are L-type bending plate.
The second locking pressure spring in the second interlocking fixed plate, the second locking pressure spring are cased on the mandril
It is equipped with the second lock pin.
The third being cased in third interlocking fixed plate on the big axis is latched pressure spring, and the third is latched pressure spring
It is equipped with third lock pin.
The first interlocking fixed plate, the second interlocking fixed plate and third interlocking fixed plate pass through rivet interlacement to described
On cabinet door frame.
The other end of the big axis is equipped with the guide plate of control earthing switch.
The guide plate is connected on the big axis by attachment screw.
Compared with prior art, the present invention have the advantage that this earthing switch of the present invention and the anti-interlock in back door,
Mandril is connected on cabinet door frame, and mandril is contacted with big axis when closing back door, and the rotation of mandril drives big axis rotation to realize control
Earthing switch；Under back door is in the open state, mandril mobile under locking pressure spring elastic force effect can be detached from big axis, and big axis is not
Can be rotated, thus can not operational grounding switch, stable realization back door is counter to be interlocked.
Detailed description of the invention
The label in content and figure expressed by the attached drawing to this specification is briefly described below:
Fig. 1 is the anti-interlock structure schematic diagram of the present invention；
In the figure, it is marked as 1, mandril, the 2, first interlocking fixed plate, the 3, second interlocking fixed plate, 4, third interlocking fixed plate,
5, the second lock pin, the 6, second locking pressure spring, 7, third lock pin, 8, third locking pressure spring, 9, big axis, 10, guide plate, 11,

Specific embodiment
Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of
Explanation.
This earthing switch of the present invention and the anti-interlock in back door are as shown in Figure 1, include mandril 1, mandril 1 is equipped with connection
Interlocking fixed plate on to cabinet door frame, one end of mandril 1, which is equipped with, is located at the big axis 9 on same axis direction with it, and back door is closed
Mandril 1 is towards big 9 direction moving contact of axis when closing；Interlocking fixed plate on mandril 1 includes the first interlocking fixed plate 2 and second
Lock fixed board 3, and the second interlocking fixed plate 3 is equipped with the second locking pressure spring 6 that supporting post-rod 1 is detached from big axis.
In the present invention, big axis 9 is equipped with the third interlocking fixed plate 4 being connected on cabinet door frame.
In the present invention, it is L-type bending that the first interlocking fixed plate 2, second, which interlocks fixed plate 3 and third interlocking fixed plate 4,
Plate.The second locking pressure spring 6 in the second interlocking fixed plate 3 is cased on mandril 1, the second locking pressure spring 6 is equipped with the second lock
Shotpin 5.
The third being cased on big axis 9 in third interlocking fixed plate 4 in the present invention is latched pressure spring 8, and third is latched pressure spring 8
It is equipped with third lock pin 7.
First interlocking fixed plate 2, second interlocks fixed plate 3 and third interlocking fixed plate 4 by rivet interlacement to cabinet door
On frame.
The other end of big axis 9 is equipped with the guide plate 10 of control earthing switch.Guide plate 10 is connected to by attachment screw 11
On big axis 9.
This earthing switch of the present invention and the anti-interlock in back door, mandril 1 are connected on cabinet door frame, and when closing back door pushes up
Bar is contacted with big axis, and the rotation of mandril 1 drives big axis rotation to realize control earthing switch；Under back door is in the open state, top
Bar 1 mobile under locking pressure spring elastic force effect can be detached from big axis, and big axis not can be rotated, thus can not operational grounding switch, surely
Fixed realization back door is counter to be interlocked.
