Description

A kind of switch cubicle switch

Technical field

The utility model relates to a kind of parts of switch cubicle, relates in particular to a kind of switch cubicle switch.

Background technology

Therefore general switch cubicle can only access a road circuit, and general switch cubicle switch only need to open and close a road circuit and get final product, with the most conventional switch, can realize the switching of switch cubicle circuit.If but switch cubicle access two-way or multiplex circuit, in the time of need to optionally connecting arbitrary road circuit, common switch can not be realized such function.

The utility model content

The utility model provides a kind of switch cubicle switch that can optionally connect multiplex circuit.In order to realize the foregoing invention purpose, the utility model has adopted following technological means:

A kind of switch cubicle switch, comprise isolation knife and solid sealed pole of vacuum arc-extinguishing chamber; The lower end of described isolation knife is fixedly connected with lobe plate; Described lobe plate is fixedly mounted on insulation spindle; Described insulation spindle rotates and is arranged on support; The lower end of described support is fixed on the solid sealed pole of vacuum arc-extinguishing chamber top; Have slotted hole on described support; On described lobe plate, cam path is set; Be installed with bearing pin in described slotted hole and cam path; Described bearing pin below is flexible coupling with conduction and moving contact links together; Described conduction is flexible coupling and connects with the isolation knife electricity; Described solid sealed pole of vacuum arc-extinguishing chamber bottom arranges fixed contact; Along with lobe plate rotates, bearing pin moves to shaft part far away from paraxial section of cam path, and then drives moving contact and be moved down into and contact energising with fixed contact.

Described slotted hole for vertically towards;

Described bearing pin is fixedly installed on excess of stroke plug; Described excess of stroke plug is slidably arranged in vertical excess of stroke pipe top; Described excess of stroke pipe is flexible coupling and is fixedly connected with moving contact with conduction by the excess of stroke screw rod in it; Between described excess of stroke screw rod and excess of stroke plug, excess of stroke stage clip is set;

Described cam path has one paraxial section and two shaft parts far away;

Described two shaft parts far away are with respect to paraxial section left-right symmetric.

The beneficial effects of the utility model are: by the isolation knife left rotation and right rotation, can optionally connect the multichannel external circuit, the moving contact that the cam path of lobe plate design simultaneously can be ordered about vacuum interrupter when isolation knife connects external circuit contacts the conducting internal circuit with fixed contact, guarantee the fail safe in switch switching process; Excess of stroke device can effectively prevent the damage caused because of vacuum interrupter dynamic/static contact wearing and tearing, extends switch useful life.

The accompanying drawing explanation

The structural representation that Fig. 1 is a kind of switch cubicle switch of the utility model;

The structural representation that Fig. 2 is lobe plate 3.

Embodiment

Below in conjunction with accompanying drawing, the preferred implementation of a kind of switch cubicle switch of the utility model is made to detailed description:

As depicted in figs. 1 and 2, this switch cubicle switch, mainly comprise isolation knife 1 and solid sealed pole of vacuum arc-extinguishing chamber 11.The lower end of isolation knife 1 is fixedly connected with lobe plate 3, and lobe plate 3 is fixedly mounted on insulation spindle 2, and insulation spindle 2 rotates and is arranged on support 10, and therefore, along with the rotation of insulation spindle 2, isolation knife 1 energy left-right rotation, in order to connect external circuit.The lower end of support 10 is fixed on solid sealed pole of vacuum arc-extinguishing chamber 11 tops.Have slotted hole 12 on support 10, slotted hole 12 for vertically towards, and be positioned on a vertical curve with insulation spindle 2.

Lobe plate 3 integral body are a fan-shaped sheet metal, insulation spindle 2 is positioned near the symmetry axis fan-shaped center of circle, cam path 4 is set on lobe plate 3, cam path 4 is W shape substantially, the fan-shaped symmetry axis left-right symmetric with respect to lobe plate 3, the centre of cam path 4 is paraxial section 42, and the two ends, left and right are shaft part 41 far away, and away from paraxial section 42 distance from insulation spindle 2 is less than, shaft part 41 is from the distance of insulation spindle 2.

Be installed with bearing pin 5 in slotted hole 12 and cam path 4, bearing pin 5 is fixedly installed on excess of stroke plug 13, excess of stroke plug 13 is slidably arranged in vertical excess of stroke pipe 6 tops, excess of stroke pipe 6 is fixedly connected with the moving contact (not shown) of vacuum interrupter by the excess of stroke screw rod 8 in it, between excess of stroke screw rod 8 and excess of stroke plug 13, excess of stroke stage clip 7 is set, conduction is flexible coupling and 9 is fixedly connected with the moving contact of vacuum interrupter by excess of stroke screw rod 8.Solid sealed pole of vacuum arc-extinguishing chamber 11 bottoms arrange fixed contact, and moving contact is relative up and down with fixed contact, and moving contact moves down energy and the closed turning circuit of fixed contact.

Conduction is flexible coupling and 9 with the lower end of isolation knife 1, is fixedly connected with and conducts.

Along with lobe plate 3 rotates, bearing pin 5 moves to shaft part 41 far away from paraxial section 42 of cam path 4, and then the moving contact that drives vacuum interrupter is moved down into the fixed contact of vacuum interrupter and contacts energising.

During use, utilizing outside output shaft to drive insulation spindle 2 turns clockwise, isolation knife 2 is from the middle open position right closing position that turns right, in this process, lobe plate 3 turns left, cam path 4 forces bearing pin 5 to promote excess of stroke plug 13 and moves down the dynamic and static contact closure conducting that makes vacuum interrupter, thereby completes the connection of interior external circuit.In like manner, need to connect the circuit in left side, only need rotate counterclockwise insulation spindle 2 and get final product.
