Abstract
Disclosed is an interlocking mechanism for an armoured central-positioned switch device cabinet door. A locking sleeve linked with a rear door is sleeved at a position of a hexahedron arranged on the tail portion of a grounded switch operation shaft, one end of the outer surface of the locking sleeve near the rear door of a cabinet body is designed into a cube, a square hole matched with the locking sleeve is disposed on an upright post on the rear side of the cabinet body, when opening or closing, the rear door drives the locking sleeve to enter or leave the square hole on the upright post on the rear side of the cabinet body so as to limit rotation of the switch operation shaft. The interlocking mechanism is capable of effectively preventing the rear door of a switch cabinet from being opened when a breaker at working position is switched on and a grounded switch is separated, thereby effectively increasing misoperation prevention level, achieving purpose of power supply safety, and guaranteeing safety of maintenance and operation workers.
Description
Technical field
The utility model relates to complete power distribution equipment, particularly armouring middle switchgear cabinet gate interlock mechanism.
Background technology
Existing KYN28A-12 type indoor metal armoring middle switchgear is the complete power distribution equipment of 3.6-12kV three-phase alternating current 50HZ single busbar connection and sectionalized single busbar connection system.Be mainly used in the power plant, medium and small generator send electricity, and being subjected to electricity, sending electricity and large-scale high-tension motor starting etc. of the secondary substation of industrial and mineral enterprises and institutions distribution and electric industry system realizes the usefulness of control protection, monitoring.Because the interlock method of existing KYN28A-12 type indoor metal armoring middle switchgear cabinet is comparatively simple, circuit breaker closes a floodgate back, earthed switch separately the time in the service position, and the cabinet back door still can be opened.Otherwise, when the cabinet door is opened, earthed switch in the same old way can deciliter, circuit breaker can divide-shut brake in the service position, the back door still can be opened in the time of can causing breaker closing, exists very big harm, and closing circuit breaker causes personnel and economic loss by mistake to cause the operation and maintenance personnel easily
The utility model content
The purpose of this utility model provides a kind of new switchgear interlocking device, can effectively solve the interlocking problem at earthed switch and cabinet back door.Having only could deciliter earthed switch when closing fully when the cabinet back door.After earthed switch separated, the cabinet back door can not be opened, and will open the cabinet back door equally, must and be in the experiment position with breaker open operation, just can open the back door after earthed switch closes.Circuit breaker is in fully and the main bus bar isolation, just can overhauls and safeguard after the cabinet effective grounding, guarantee attendant's safety.
The technical solution of the utility model is, this interlocking device is the hexahedron that utilizes earthed switch operating axis afterbody, at the lock tube of the hexahedron place of earthed switch operating axis afterbody suit one with the back door interlock, the lock tube outer surface is designed to non-circular body near cabinet back door one end, have the non-circular hole that is complementary with lock tube on the cabinet rear side column, when the back door opened or be closed, the drive lock tube entered or leaves the non-circular hole on the cabinet heel post, thus the rotation of limit switch operating axis.When open at the back door, because lock tube can not rotate in the non-circular hole of cabinet heel post, making with it, the earthed switch operating axis of one also can't rotate, can not deciliter earthed switch, earthed switch and circuit breaker reciprocal interlocking relation, circuit breaker cart can not arrive the service position, and main bus bar and outlet side are isolated fully.In the time of need sending electricity, back door closure, lock tube leave the non-circular hole of cabinet heel post, no longer are tied, and at this moment the earthed switch operating axis just can rotate, can deciliter earthed switch, circuit breaker just can push to from the experiment position service position also combined floodgate power.
This interlock can prevent effectively that circuit breaker from closing a floodgate back and earthed switch when separating in the service position, and the switch cubicle back door can not be opened.Effectively improve the anti-misoperation grade, reach the purpose of safe power supply.Guarantee maintenance and operation personnel's safety

Embodiment
As shown in the figure, the hexahedron place of earthed switch operating axis 1 afterbody is set with lock tube 6, is opening a square hole on the column 4 of left side behind the switch cubicle, and lock tube 6 appearances also are designed to square near cabinet back door one end.Between earthed switch operating axis 1 and the cabinet heel post 4 limiting plate 5 is installed, stage clip 7 is housed on the lock tube 6.When door 9 opens, lock tube 6 moves to cabinet heel post 4 under the effect of stage clip 7, up to moving to limiting plate 5 places, this moment, the cubic position of lock tube 6 entered the cubic hole 12 on the column of left side behind the cabinet fully, this hole, four directions scope of design is (32mm-45mm) * (32mm-45mm), behind the cubic hole 12 on the left of the cubic position of lock tube 6 enters on the column, because the hexagonal hole of lock tube 6 is to be enclosed within on the hexahedron of earthed switch power transmission shaft 1 afterbody, earthed switch operating axis 1 just can't be rotated to divide the ground connection switch, earthed switch and circuit breaker reciprocal interlocking relation, circuit breaker cart can not arrive the service position, and main bus bar and outlet side are isolated fully.
In the time of need sending electricity, must fasten back door 9, when lock tube 6 at closing time moves to earthed switch operating axis 1 under the effect at back door 9, the stage clip compression, the cubic hole 12 on the column of left side is left at the cubic position of lock tube 6 when fit with cabinet heel post 4 in back door 9, at this moment earthed switch operating axis 1 could rotate, just can deciliter earthed switch.
Back Xiamen is opened the corresponding section and is had an interlocking cylindrical void 11, and after earthed switch separated, the L parts of lock tube 6 can pin back door 9 by machinery.Circuit breaker just can be pushed the service position and the power supply of closing a floodgate from the experiment position to.Gate interlock hole 11 can be made into the T type behind the lock tube of this interlock and the cabinet
When needing interruption maintenance to open back door 9, must divide circuit breaker earlier, circuit breaker cart is moved to the experiment position from the service position, the earthed switch that closes just can be opened the back door.
