Abstract
The utility model discloses an interlocking device for a double-throw disconnecting switch. The interlocking device comprises two crank arms which can be respectively and fixedly installed on two operation shaft bodies, wherein free ends of the two crank arms are respectively hinged with one ends of two forks, and a hinge structure of one crank arm and one end of one of the forks is a relatively slidable hinge structure; and the free ends of the two forks are connected into a whole through a connecting rod. The purpose of directly arranging the interlocking device onto the switch is realized through two crank arms which can be respectively fixed on the two operation arms of the disconnecting switch. During the operation, the slidable hinge structure at one end of the device is utilized, so two operation shafts can only rotate in two states, namely, one operation shaft is set to rotate towards the closing direction or both the operation shafts simultaneously rotate towards the closing direction, accordingly, the mechanical interlocking function that only one path is closed at any time, or both the two paths are under the action of a closing state can be realized.
Description
[technical field]
The utility model relates to a kind of double-throw disconnecting switch interlock.
[background technology]
Double end isolating switch interlock is to guarantee the double-throw disconnecting switch safety utilization of electric power, stops the necessary device of potential safety hazard.GN27-40.5 double-throw disconnecting switch for example; Its power supply is imported from the centre, and two output is owing to be mainly used in same high-voltage motor triangle star connection; For preventing short circuit accident; Requiring must have mechanical interlocking between two operating axis, with reach at any time can only have one the road closed, or two the tunnel all be in gate-dividing state purpose.The interlock of existing double-throw disconnecting switch, because of independently being installed on the cabinet with the isolating switch split, the user needs to be equipped with separately, and not only complex structure and production cost are higher.
[summary of the invention]
For solving the problems referred to above that prior art exists; The utility model aims to provide a kind of double-throw disconnecting switch interlock; After existing double-throw disconnecting switch is directly prepared this device, can realize the mechanical interlocking purpose, and have advantage simple in structure, that production cost is low.
For realizing above-mentioned purpose; The utility model has adopted following technical scheme: this double-throw disconnecting switch interlock; It is characterized in that: have two and can be fixedly mounted on two connecting levers on the operating axis axle body respectively; The free end of these two connecting levers is articulated and connected with an end of two brackets respectively, and the articulated structure of one of them connecting lever and said bracket one end is slideable relatively articulated structure; The free end of said two brackets is connected into integral body through connecting rod.
During as preferred practical implementation; Saidly be fan-shaped for the connecting lever shape of slidingtype articulated structure; The inboard of this fan-shaped connecting lever has one can be with the connecting bushing that himself is fixed on the operating axis; The outside has the arc chute that an admittance is used to connect the swivel pin of bracket, and said bracket and fan-shaped connecting lever can be done relative motion by this swivel pin and arc chute.
During as preferred practical implementation, the two ends of said connecting rod are screw rod, are connected into integral body through adjusting nut bracket corresponding with it respectively.
Beneficial effect: compared with prior art, the utility model has realized on switch, directly being provided with the purpose of interlock through two connecting levers that can be respectively fixed on two operating axis of isolating switch.During operation; Utilize bracket and fan-shaped connecting lever can make the characteristic of relative motion by swivel pin and arc chute; Make two operating axis can only realize the rotation of two states, that is: or select one and rotate, or rotate to the separating brake direction simultaneously to the combined floodgate direction; Thereby realized at any time can only having one the road closed, or two the tunnel all be in gate-dividing state the mechanical interlocking function.
For deepening understanding, make further detailed description through embodiment below in conjunction with accompanying drawing to the utility model.
[description of drawings]
Fig. 1 is the main TV structure sketch map of an embodiment of the utility model.
Fig. 2 is a kind of variable condition structural representation of Fig. 1.
Fig. 3 is another variable condition structural representation of Fig. 1.
Fig. 4 to Fig. 6 is followed successively by the application state structure key diagram of Fig. 1 to Fig. 3
Among the figure: operating axis 1, fan-shaped connecting lever 2, jump ring 3, swivel pin 4, arc chute 41, bracket 5, connecting rod 6, bracket 7, hinged block 8, connecting lever 9, operating axis 10.Underframe 20, sleeve pipe 21, electric power incoming line 211, pillar 22, pull bar 23, contact knife 24, contact knife 25, pull bar 26, power outlet 27, power outlet 28.
[embodiment]
Referring to Fig. 1.The structure of this double end isolating switch interlock, by fan-shaped connecting lever 2, the connecting lever 9 that can be fixedly installed on respectively on operating axis 1 and 10 axle bodies, and two brackets 5 and 7, connecting rods 6 formations.Fan-shaped connecting lever 2 fixed covers are located on the axle body of operating axis 1; Its free end is combined to form the slidingtype articulated structure through arc chute 41 and swivel pin 4 and jump ring 3 thereof; Utilize swivel pin 4 and fan-shaped connecting lever 2 can make the characteristic of relative motion, make bracket 5 and operating axis 1 also can do relative motion.One end of bracket 7 also is hinged through swivel pin and jump ring with the free end that is fixed on the connecting lever 9 on the operating axis 10.
Two brackets 5 and 7 free end are connected into integral body through connecting rod 6, and for ease of dismounting with install, the two ends of said connecting rod are screw rod, are connected into integral body through adjusting nut and corresponding bracket respectively.
Among Fig. 1: operating axis 1 is in closing position (the fan-shaped connecting lever 2 of this moment is in the left dead-centre position that is rotated counterclockwise), and operating axis 10 is in brake-dividing locking position (connecting lever 9 of this moment also is in the left dead-centre position that is rotated counterclockwise).Because fan-shaped connecting lever 2 can slide through arc chute 41 relative swivel pins 4, therefore, this moment, operating axis 1 can rotate to clockwise direction; Make sub-switching operation, also can rotate counterclockwise once more behind the separating brake, do the operation of closing a floodgate; And operating axis 1 is when closing, and operating axis 10 can only be in a minute position.
Among Fig. 2: operating axis 1 is in brake-dividing locking position (the fan-shaped connecting lever 2 of this moment is in the right dead-centre position that turns clockwise), and operating axis 10 is in closing position (connecting lever 9 of this moment also is in the right dead-centre position that turns clockwise).This moment, operating axis 10 can rotate counterclockwise, that is: carry out sub-switching operation, and can clockwise rotate once more behind the separating brake, did the operation of closing a floodgate.And operating axis 10 is when closing, and operating axis 1 can only be in a minute position.
Among Fig. 3: operating axis 1, operating axis 10 all are in the separating brake position.At this moment, operating axis 1, operating axis 10 operation that all can take the lead in closing, dividing.
Referring to Fig. 4, Fig. 5 and Fig. 6.This three width of cloth figure is the variable condition of this interlock among corresponding diagram 1, Fig. 2 and Fig. 3 respectively, explain that GN27-40.5 double end isolating switch assembles this device after, the pull bar 23 on the isolating switch, contact knife 24, contact knife 25, the situation of change of pull bar 26.
The foregoing description only as explanation, explain the usefulness of the utility model, and should not limit the application's protection range, any variability technical scheme of making according to teachings herein all should be included the application's protection range in.
