Background technology
The interlocking of high-tension switch cabinet is to ensure power network safe operation, ensure equipment and personal safety, prevent maloperation
Important measures.GB3906《3-35kV ac metal closing switch gears》This is also made explicit provisions.Typically interlocking is described
For：Prevent mistake point, falsely close circuit breaker；Prevent on-load point, close disconnecting switch；(ground connection is opened to prevent band cable address (conjunction) ground wire
Close)；Prevent line with ground (switch) from closing breaker, on-load switch：Prevent mistakenly entering charged chamber；Above-mentioned five prevent from electrically grasping by mistake
The content of work, referred to as " five prevent ", " five prevent " device generally can be divided into machinery, electric and comprehensive three classes；At present, in the market is high presses off
Close cabinet type a lot, it is most of to have more perfect interlock method, but still have the interlocking of many high-tension switch cabinets especially mechanical
Interlocking imperfection, can not still be fully achieved " five prevent " and require.
For the ease of repair and maintenance, middle-placed switch cabinet back door is mostly using two sides articulate door；Cable chamber door is opened by ground connection
Close operating mechanism interlock and realize interlocking, when earthed switch is in gate-dividing state, the lock tube in earthed switch operating shaft
The perforate direction of boss and cable chamber door differ from 90 °, so as to pin cable chamber door, cause cable chamber door to open, prevent people
The cable vault of member's mistakenly entering into charged, only when the operating shaft of earthed switch rotates earthed switch to "on" position (90 °), on lock tube
When boss is consistent with the perforate direction of cable chamber door, the opening that cable chamber door can be safe.
But this cable chamber door interlocking mechanism existing defects, i.e.,：But after cable chamber door is opened, can still not close cable
Direct operational grounding is switched to separating brake, the interlocking of releasing and breaker, breaker is carried out combined floodgate behaviour in the case of room
Make；Because cable chamber door is not turned off, cable vault is powered to be easy to lead to personal safety accident, it is impossible to is met " five prevent " and is required.
Utility model content
The utility model proposes a kind of 6-35kV middles high voltage power distribution switch cubicle cable chamber door interlocking mechanism, its mesh
Aim to solve the problem that the defect that existing cable room door interlocking mechanism is present；Make the opening of cable chamber door, closing can be to earthed switch
Point, close a floodgate be controlled：Only when cable chamber door is closed, earthed switch could be carried out point, closing operation；Only when connecing
When ground switch closes a floodgate, cable chamber door could be opened：And once cable chamber door is opened, earthed switch cannot be carried out point, closed a floodgate
Operation.
Technical solution of the present utility model：A kind of 6-35kV middles high voltage power distribution switch cubicle cable chamber door interlocking machine
Structure, its structure includes cable chamber door 1, lock tube 2, right lateral side plate 3, back-moving spring 4, earthed switch operating shaft 6, mounting bracket 8；Its
In, slot 9 is provided with cable chamber door 1, the right side of cable chamber door 1 connects right lateral side plate 3, square is provided with right lateral side plate 3
Hole 10, the two sides of right lateral side plate 3 are fixed with mounting bracket 8, and circular hole is provided with mounting bracket 8, and earthed switch is installed with circular hole
Operating shaft 6, one end of lock tube 2 passes through the square hole 10 on slot 9 and right lateral side plate 3 on cable chamber door 1, lock tube 2
The other end be enclosed within earthed switch operating shaft 6；Back-moving spring 4 is housed between lock tube 2 and earthed switch operating shaft 6.
Advantage of the present utility model：
1）Simple structure, be easily achieved, if one lock tube of processing, without be modified to original cabinet body structure
Realize；
2）When can ensure that cable chamber door is opened, earthed switch it is reliably not charged in "on" position, cable vault, ensure people
The safety of body, meets " five prevent " and requires；
3）Interlocking mechanism is reasonable in design, easy for installation, using reliability, and be largely used on middle-placed switch cabinet, achieve very
Good safety protective effect.

Specific embodiment
A kind of control accompanying drawing, 6-35kV middles high voltage power distribution switch cubicle cable chamber door interlocking mechanism, its structure includes electricity
Cable room door 1, lock tube 2, right lateral side plate 3, back-moving spring 4, earthed switch operating shaft 6, mounting bracket 8；Wherein, on cable chamber door 1
Slot 9 is provided with, the right side of cable chamber door 1 connects right lateral side plate 3, square hole 10, right lateral side plate 3 are provided with right lateral side plate 3
Two sides be fixed with mounting bracket 8, circular hole is provided with mounting bracket 8, earthed switch operating shaft 6 is installed with circular hole, lock tube 2
One end is enclosed within ground connection through the square hole 10 on the slot 9 and right lateral side plate 3 on cable chamber door 1, the other end of lock tube 2
On switching manipulation axle 6；Back-moving spring 4 is housed between lock tube 2 and earthed switch operating shaft 6.
The lock tube 2 includes T connector 2-1, hexagonal boss 2-2, square protrusions 2-3, cylindrical cavity 2-4, slotted eye 2-5.
Slot 9 on the extended cable chamber doors 1 of T connector 2-1.
The hexagonal boss 2-2 is between square protrusions 2-3 and cable chamber door 1.
It is back-moving spring 4 between the cylindrical cavity 2-4 and earthed switch operating shaft 6.
The lock tube 2 is connected by the pin 5 in slotted eye 2-5 with earthed switch operating shaft 6.
The slotted eye 2-5 is rectangle, and pin 5 can be moved forward and backward in slotted eye 2-5, so that lock tube 2 is in reset bullet
Can be movable along earthed switch operating shaft 6 under spring effect.
The mounting bracket 8 is fixed on the two sides of right lateral side plate 3 by screw 7.
Control accompanying drawing 3, when close cable chamber door 1 when, cable chamber door 1 push down hexagonal boss 2-2, back-moving spring 4 compressed,
Lock tube 2 is moved backward relative to earthed switch operating shaft 6, and square protrusions 2-3 exits the square hole 10 of right lateral side plate 3, solution
Except on right lateral side plate 3 square hole 10 to earthed switch point, the limitation of closing operation；Now, operational grounding switch is at
In gate-dividing state, earthed switch operating shaft 6 drives lock tube 2 to rotate, make oblong aperture on T connector 2-1 and cable chamber door 1 into
900Angle, pins cable chamber door, and when reliably ensure that earthed switch is in gate-dividing state, cable chamber door can not be opened.
Control accompanying drawing 4, because cable chamber door 1 is closed, relieve square hole on right lateral side plate 3 to earthed switch point,
The limitation of closing operation；So, when needing to make earthed switch be in "on" position, can be at being in operational grounding switch
"on" position, earthed switch operating shaft drives lock tube 2 to rotate, and makes oblong aperture on T connector 2-1 and cable chamber door 1 into 00Angle, solution
Except the interlocking of oblong aperture on T connector and cable chamber door, cable chamber door can be now opened.
Control accompanying drawing 5, after cable chamber door 1 is opened, hexagonal boss 2-2 loses cable chamber door pressure, the reset bullet for being compressed
Spring recovers, and drives axle sleeve 2 to be moved forward relative to earthed switch operating shaft 6, and square protrusions 2-3 enters on right lateral side plate 3
Square hole, square protrusions 2-3 can not be rotated in this square hole, it is impossible to carry out the sub-switching operation to earthed switch, from
And cable chamber door is ensure that in open mode, earthed switch is reliably in contact of earth state；Cable chamber door is prevented to beat
Under open state, there is the possibility between mistakenly entering into charged, " five prevent " function of perfect middle-placed switch cabinet.
