Abstract
The invention relates to the field of interlocking devices of switch cabinets, in particular to a mechanical interlocking device. The mechanical interlocking device comprises a bottom plate, an interlocking middle plate, an assembly panel, a spring guide rod, an interlocking spring and an interlocking shaft. A fixed pin is arranged on the interlocking middle plate, a guide hole is formed in the lower end of the assembly panel and matched with a pin shaft, and the assembly panel can move up and down relative to the interlocking middle plate. The mechanical interlocking device meets the locking requirements for successive motion through operating components of an interlocked circuit breaker and a disconnecting switch, solves the misoperation problem, and ensures safety of equipment and staff; moreover, a positioning part of the bottom plate of the device is changed to be the round pin from a traditional strip type clamping plate, and the positioning effect is enhanced; a traditional eccentric arrangement is changed to be a collinear arrangement for the center line of the guide hole and the center line of the assembly panel, so that the device is not prone to deforming and good in positioning, and slides flexibly.
Description
Technical field
The present invention relates to interlocking device of switch cabinet field, refer in particular to a kind of mechanical interlocks.
Background technology
Switch cubicle, for preventing misoperation, reduces security incident, and mechanical interlocks is often set, but the interlock method imperfection of part mechanical interlocks, reliability and fail safe are low, and misoperation phenomenon happens occasionally.Solve misoperation problem, need to guarantee the Interlock Reliability between circuit breaker and isolating switch.
The keeper of mechanical interlocks is the long strip type clamp that is embedded in lower door-plate location hole, and long strip type clamp intensity is low, poor stability, and locating effect is very limited.Assembling panel lower end be provided with interlock in the hinged pilot hole of plate, the center line eccentric setting of pilot hole and assembling panel, panel bending strength is low, a little less than bearing capacity, easy modification, and locating effect is poor, slides dumb.
Summary of the invention
The object of the invention is to overcome the defect of prior art, provide a kind of Interlock Reliability strong, can prevent misoperation, and not flexible type, the mechanical interlocks flexibly of having good positioning, slide.
For achieving the above object, the present invention adopts following technical scheme:
A kind of mechanical interlocks, comprise plate in base plate, interlocking, assembling panel, spring guide, interlocking spring and interlocking shaft, in interlocking, on plate, have a fixing pin, assembling panel lower end be provided with the pilot hole matching with pin axle, assembling panel can relatively interlock in plate move up and down.
Assembling panel upper end central authorities are provided with isolating switch and earthed switch handle hole, and lower end is provided with the interlocking bent plate of interlocked circuit breaker divide-shut brake button; Interlocking shaft is arranged on assembling panel, can move up and down perpendicular to assembling panel; Plate upper end in interlocking is fixed in spring guide bottom, and through the pin-and-hole on interlocking shaft, split pin is inserted with restriction interlocking shaft stroke in top.
While pressing breaker closing button, combined floodgate direction board drives assembling panel to move downward, and blocks isolating switch and earthed switch handle hole; Interlocking shaft moves downward with assembling panel, and interlocking spring compression is reset (breaker open operation) energy storage of assembling panel.
Isolating switch and earthed switch handle hole are when open position, and assembling panel is displaced downwardly to minimum point, and the interlocking bent plate that breaker closing knob is assembled panel blocks and cannot press.
Base plate is provided with location round pin, matches with the location hole of lower door-plate.
The center line of pilot hole and the centerline collineation that assembles panel.
The present invention is by interlocking isolating switch and circuit breaker, solves misoperation problem, has guaranteed equipment and personal security, and by the pilot hole of the keeper of base plate and assembling panel is improved, has strengthened the locating effect of device, improves the flexibility that device slides.
accompanying drawing explanation:
Accompanying drawing 1 is the present invention's structural representation;
The left view that accompanying drawing 2 is Fig. 1.
embodiment:
In order to make juror can the present invention's object, feature and function be had further and be understood, hereby lift preferred embodiment and coordinate graphic being described in detail as follows:
Refer to shown in Fig. 1 or Fig. 2, it is the structural representation of the present invention's preferred embodiment, the present invention is relevant a kind of mechanical interlocks, comprise plate 2 in base plate 1, interlocking, assembling panel 3, spring guide 4, interlocking spring 5 and interlocking shaft 6, in interlocking, on plate 2, there is a fixing pin, assembling panel 3 lower ends be provided with the pilot hole 7 matching with pin axle, assembling panel 3 can relatively interlock in plate 2 move up and down.
Assembling panel 3 upper end central authorities are provided with isolating switch and earthed switch handle hole 8, and lower end is provided with the interlocking bent plate 9 of interlocked circuit breaker divide-shut brake button; Interlocking shaft 6 is arranged on assembling panel, can move up and down perpendicular to assembling panel; Plate upper end in interlocking is fixed in spring guide 4 bottoms, and through the pin-and-hole on interlocking shaft, split pin is inserted with restriction interlocking shaft 6 strokes in top.
While pressing breaker closing button, combined floodgate direction board drives assembling panel 3 to move downward, and blocks isolating switch and earthed switch handle hole 8, and isolating switch can not be operated, and prevents that on-load from dividing, closing isolating switch.Interlocking shaft 6 moves downward with assembling panel, and interlocking spring 5 compressions are reset (breaker open operation) energy storage of assembling panel.
Isolating switch and earthed switch handle hole 8 are when open position, and assembling panel 3 is displaced downwardly to minimum point, and the interlocking bent plate 9 that breaker closing knob is assembled panel blocks and cannot press, thereby prevents from closing circuit breaker by mistake, has guaranteed equipment and personal security.
The keeper of base plate changes location round pin 10 into by traditional long strip type clamp, has strengthened locating effect; Pilot hole 7 changes conllinear with the center line of assembling panel into by traditional eccentric setting, make device not flexible type, have good positioning, slide flexibly.
