Embodiment
Below in conjunction with accompanying drawing, detailed description is made to the preferred implementation of a kind of many electric power incoming lines of the present invention switch cubicle:
As shown in Figure 1, Figure 2 and Figure 3, this switch cubicle, mainly comprises cabinet 17, and the left and right sides, top of cabinet 17 arranges left electric power incoming line 14 and right electric power incoming line 15 respectively.Cabinet 17 inside is provided with the switch 16 optionally connecting left electric power incoming line 14 or right electric power incoming line 15, and switch 16 is positioned at below both left electric power incoming line 14 and right electric power incoming line 15 center line.
Switch 16 comprises 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 arranges over the mount 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 top.Support 10 has elongated hole 12, elongated hole 12 be vertically towards, and to be positioned on a vertical curve with insulation spindle 2.
Lobe plate 3 entirety is a fan-shaped sheet metal, insulation spindle 2 is positioned on the symmetry axis near the fan-shaped center of circle, lobe plate 3 is arranged cam path 4, cam path 4 is substantially in W shape, the symmetry axis fan-shaped relative to lobe plate 3 is symmetrical, the interposition of cam path 4 paraxial section 42, 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.
Bearing pin 5 is installed with in elongated 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 top, 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, arrange excess of stroke stage clip 7 between excess of stroke screw rod 8 and excess of stroke plug 13, 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 bottom arranges fixed contact, and moving contact and fixed contact are relative up and down, and moving contact moves down energy and fixed contact closes turning circuit.
Conduction is flexible coupling and 9 is fixedly connected with the lower end of isolation knife 1 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 drives the moving contact of vacuum interrupter to be moved down into contact with the fixed contact of vacuum interrupter and be energized.When the dynamic and static contact of vacuum interrupter is connected, isolation knife 1 is just in time connected with left electric power incoming line 14 or right electric power incoming line 15 and is energized, and also namely when bearing pin 5 forwards shaft part 41 far away to, isolation knife 1 contacts with left electric power incoming line 14 or right electric power incoming line 15.
During combined floodgate, two closing positions pull operation mechanism output shaft is utilized to drive insulation spindle 2 to turn clockwise, isolation knife 2 swings to right closing position (contacting with right electric power incoming line 15) to the right from the open position of centre, in this process, lobe plate 3 swings left, the moving contact that cam path 4 forces bearing pin 5 to promote vacuum interrupter is moved down into and contacts conducting with the fixed contact of vacuum interrupter, thus completes the connection of interior external circuit.
During separating brake, two closing positions pull operation mechanism output shaft is utilized to drive insulation spindle 2 to be rotated counterclockwise, in rotary course, first isolation knife 1 departs from right electric power incoming line 15, when lobe plate 3 forwards paraxial section 41 to, the dynamic and static contact of vacuum interrupter is separated, the electric arc produced when contact is separated extinguishes in a vacuum, completes separating brake.
In like manner, need to connect left electric power incoming line 14, two closing position mechanisms output shaft only need be utilized to rotate counterclockwise insulation spindle 2, be separated left electric power incoming line 14, two closing position mechanisms output shaft only need be utilized to rotate clockwise insulation spindle 2.
