Abstract
An interlocking device of ground switch and door of switch apparatus belongs to the technical field of electric appliances, which comprises a ground switch operating shaft which is mounted on the lateral board of a switch cabinet. The interlocking device is characterized by comprising a fan-type piece which is mounted on one side of the lateral board, a connecting rod, a hook, a pin shaft and a fixed pin and a supporting stand which are mounted on one side of the cabinet door, wherein the fan-type piece is mounted on the operation shaft of the ground switch and is hinged with the upper end ofthe connecting rod, the lower end of the connecting rod is hinged with the hook, the hook is pivoted with the cabinet door through a pin shaft, the fixed pin is mounted on the supporting stand, the supporting stand is fixed on the cabinet door, the front end of the hook is provided with a notch, and the notch is matched with the fixe pin. The interlocking device can lead the ground switch of the switch apparatus to reliably interlock with the cabinet door of the switch apparatus.
Description
Technical field
The utility model relates to a kind of electric device, refers to the interlock of a kind of switchgear grounding switch and switch cubicle door especially.Belong to technical field of electric appliances.
Background technology
High pressure armored withdraw type ac metal closing switch gear (hereinafter to be referred as switchgear), " five is anti-" according to national standard and safety regulation for operations requires: require to prevent mistakenly entering charged chamber under equipment charging operation situation, necessary off switch equipment cabinet door before the energising operation, earthed switch is in gate-dividing state, earthed switch and cabinet gate interlock are in closure state, guarantee that the cabinet door does not allow to open; Need maintenance or other situation occurs to open cabinet door circuit breaker, the earthed switch that closes is removed the interlocking of earthed switch and cabinet door and just can be opened the switchgear cabinet door.The design of the former interlocking of KYN28A switchgear is to install and fix an open stand with bolt on the switchgear cabinet door, close cabinet and operate the rotation earthed switch behind the door, the descending pinning open stand of fanning strip indentation neck blocking lever achieves interlocking on the earthed switch operating axis.There is following defective in the method: first open stand is long, opens that switch cubicle is easy to be operated behind the door or the maintainer runs into and causes that position angle changes, and also can hinder operation or maintainer; The position angle of second open stand change easily makes interlocking very unreliable; , the 3rd earthed switch and switch cubicle gate interlock or earthed switch operating mechanism want very low, the very little and inconvenient observation in emergency release hole of emergency opening cabinet door if breaking down, so that emergency release is very inconvenient.
Summary of the invention
The device that provides a kind of switchgear grounding switch and equipment cabinet door reliably to interlock is provided the purpose of this utility model.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model includes the earthed switch operating axis that is loaded on the switch cubicle door, it is characterized in that, include: be loaded on fan matrix, connecting rod, hook, the bearing pin of cabinet side plate one side and be loaded on steady pin, the support of cabinet door one side, the fan matrix is loaded on the earthed switch operating axis and is hinged with the upper end of connecting rod; The lower end of connecting rod is hinged with hook; Hook connects by bearing pin and cabinet hingen; Steady pin is loaded on the support, and support is fixed on the doorframe, and the front end of hook has a recess, and this recess and steady pin match.
The beneficial effects of the utility model are: switchgear grounding switch and equipment cabinet door can reliably be interlocked, and open to be not easy behind the door to be operated or the maintainer runs into and causes that position angle changes, and can not hinder operation or maintainer yet; The position angle of second open stand can not change, interlock reliable; Can open the cabinet door easily and carry out emergency release.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1 be the earthed switch operating axis, 2 for the fan matrix, 3 for connecting rod, 4 for hook, 5 for steady pin, 6 for support, 7 for bearing pin, 8 for the cabinet side plate, 9 for cabinet door, 41 for recess.
Embodiment
Referring to accompanying drawing, the utility model includes the earthed switch operating axis 1 that is loaded on the switch cubicle side plate 8, it is characterized in that, include: be loaded on fan matrix 2, connecting rod 3, hook 4, the bearing pin 7 of cabinet side plate 8 one sides and be loaded on steady pin 5, the support 6 of cabinet door 9 one sides, fan matrix 2 is loaded on the earthed switch operating axis 1 and is hinged with the upper end of connecting rod 3; The lower end of connecting rod 3 is hinged with hook 4; Hook 4 articulates by bearing pin 7 and cabinet door 9; Steady pin 5 is loaded on the support 6, and support 6 is fixed on the cabinet door 9, and the front end of hook 4 has a recess 41, and this recess 41 matches with steady pin 5.
Off switch equipment cabinet door 9 locking door locks, operating personnel rotate earthed switch operating axis 1 and make the earthed switch separating brake, earthed switch operating axis 1 drives fan matrix 2 and moves downward when rotating, fan matrix 2 drivening rods 3 drive hook 4 downwards and rotate around bearing pin 7, thereby the recess 41 of linking up with 4 front ends blocks steady pin 5 locking cabinet doors 9, has finished the interlocking of earthed switch and switchgear cabinet door.Operating personnel's backward rotation earthed switch operating axis 1, the recess 41 of linking up with 4 front ends breaks away from steady pin 5, finishes the release of earthed switch and switchgear cabinet door.
