Abstract
The invention discloses a three-position switch used for a gas insulated metal-enclosed switchgear. A movable side conductor and an insulated flange are connected by bolts so as to ensure the pressing force of a joint surface; the fixed contact of an isolating switch and a feather key are connected by screw threads; a high-speed grounding switch, a grounding switch and a metal container are connected and fastened by bolts and seal rings; the moving contact of the isolating switch, a connecting plate 5, a crank arm, a connecting plate 7 and the moving contact of the grounding switch are connected by shaft pins and check rings; and the high-speed grounding switch, the ground connection units of the grounding switch are connected with a ground connection copper bar and the metal container by bolts. The invention has unique mechanism, reliable movement, easy production and high reliability, effectively avoids the problem of mutual interference among three phases of a nonsegregated switch and is especially suitable for outdoor intelligentized substations having high demands on product performance.
Description
Technical field
The present invention relates to a kind of high voltage switchgear, be specifically related to a kind of three position switch that is used for Cubicle Gas-Insulated Switchgear.
Background technology
The traditional switchgear that has at present this function on the market generally by two structures independently switchgear forms i.e. isolating switch and earthed switch composition.Isolating switch has independently housing, moving side conductor, quiet side conductor and operating mechanism, cardinal principle is that the operating mechanism rotation drives moving side conductor rotation or rectilinear motion, moving side conductor rotation or rectilinear motion insert quiet side conductor and realize that isolating switch closes, and moving side conductor rotation or rectilinear motion leave quiet side conductor and realize the isolating switch branch; Earthed switch also has independently housing, moving-conductor, quiet conductor and operating mechanism, cardinal principle is that the operating mechanism rotation drives moving-conductor rotation or rectilinear motion, moving-conductor rotation or rectilinear motion insert quiet conductor and are grounded switch and close, and moving-conductor rotation or rectilinear motion leave quiet conductor and be grounded the switch branch.
The recent domestic three-station that also occurred, these three-stations are made of moving side and quiet side mostly, be rotated or rectilinear motion by moving side conductor, enter or withdraw from the quiet side conductor of contact, the isolation splice grafting ground that has three stations to finish three-station divides, isolates and divide ground connection branch, isolation to divide ground connection and three operations, isolation and ground unit are the mechanical latching structures, and the branch of common case and branch mailbox is arranged.Complex structure, non-uniform electric, failure rate height.Though the mechanism structure project organization that also has is simple but cost is higher, complex process.
Summary of the invention
The present invention is directed to above-mentioned weak point, research and develop the box three-station equipment of a kind of novel branch, can finish above-mentioned isolation and grounding function.
Technical solution of the present invention:
A kind of three position switch that is used for Cubicle Gas-Insulated Switchgear is characterized in that: connect to guarantee the thrust of faying face by bolt between moving side conductor and the insulating flange; Static contact isolation switch and guide connect fastening by bolt, sealing ring by being threaded between high speed grounding switch, earthed switch and the canister; Connect by pivot pin, back-up ring between isolating switch moving contact, connecting plate 5, connecting lever, connecting plate 7, the earthed switch moving contact; The ground connection of high speed grounding switch, earthed switch is connected with ground connection copper bar, canister by bolt.
Beneficial effect of the present invention: this switchgear has the repertoire of isolating switch and earthed switch, and can realize the mechanical interlocked of isolating switch and earthed switch, can finish isolation splice grafting ground divides, isolates and divide ground connection branch, isolation branch ground connection to close three stations, mechanism's uniqueness, reliable in action is easy to produce, and effectively avoids the problem that interferes with each other between the common case switch three-phase, the reliability height especially is fit to the intelligent transformer station in the demanding open air of properties of product.
Description of drawings
Accompanying drawing is a generalized section of the present invention.
Embodiment
Moving side conductor 2 is installed on the insulating flange 15.It is the center rotation with six square shafts that the three position mechanism insulated tension pole drives two-way connecting lever 6, when being rotated counterclockwise, connecting lever 6 moves upward with connecting plate 5 promotion isolating switch moving contacts 4 and contacts with the guide 3-1 of static contact isolation switch 3, and the contact forms current lead-through, and this has just finished and has isolated the operation of closing; When connecting lever 6 was rotated counterclockwise simultaneously, drive connecting plate 7, earthed switch moving contact 8 moved right, and the earthed switch moving contact does not contact with earthed switch fixed contact 9-1 for 8 this moments, thereby realizes mechanical latching.
It is that the center is when turning clockwise certain angle with six square shafts that three position mechanism drives two-way connecting lever 6, connecting lever 6 and connecting plate 5 pulling isolating switch moving contacts 4 move downward to separate with the guide 3-1 of static contact isolation switch 3 and just enter that circuit disconnects in the moving side conductor 2, and this has just finished the operation of isolating branch; This moment, connecting lever 6 was when turning clockwise, and drove connecting plate 7, earthed switch moving contact 8 to left movement but still be in the moving side conductor 2.Realize that the isolation of three stations divides the ground connection branch this moment.
It is the center certain angle that turns clockwise with six square shafts that three position mechanism continue to drive two-way connecting lever 6, and connecting lever 6 and connecting plate 5 pulling isolating switch moving contacts 4 move downward and enter in the moving side conductor 2 position that this moment, isolating switch was still punished; When simultaneously connecting lever 6 turns clockwise, drive connecting plate 7, earthed switch moving contact 8 and leave moving side conductor 2 to left movement and enter in the earthed switch 12 and contact with earthed switch 9-1, this moment moving side conductor 2 and earthed switch 12 connections are grounded switch and close the isolating switch branch.
To sum up, the action of isolating switch and earthed switch is mechanical interlocked.
Closing of high speed grounding switch 10: high speed grounding switch mechanism drives axle 12 and turns clockwise, drive connecting lever 13, connecting lever 13 promotes to have the moving contact 11 of slotted hole to move right with guide 3-2 in the static contact isolation switch 3 and contact the closing operation of contacting realization high speed grounding switch 10.
The branch of high speed grounding switch 10: high speed grounding switch mechanism drives axle 12 and is rotated counterclockwise, drive connecting lever 13, connecting lever 13 pullings have the guide 3-2 disconnection of moving contact 11 in left movement and static contact isolation switch 3 of slotted hole to enter in the high speed grounding switch 10, realize the branch operation of high speed grounding switch 10.
Earthed switch moving contact 8 and isolating switch moving contact 4 reliably are connected by the fingertip of relying on oneself with moving side conductor 2 conductings.The ground connection of earthed switch 9, high speed grounding switch 10 is connected with canister 1 by ground connection copper bar 14.
The present invention has realized the reasonable distribution of circuit electric field, and moving side conductor 2 two ends conductors all are that columned uniform electric field distributes.Earthed switch 12, high speed grounding switch 10 can be matched as required, and therefore simple in structure, reliable in action has bigger benefit to making and moving.
