Switch cabinet valve opening and closing device

[0022] refer to Figure 1 to Figure 7 , a switchgear valve opening and closing device is characterized in that it comprises an upper valve insulating plate 1, a lower valve insulating plate 2, an upper insulating plate fixing support 5, a lower insulating plate fixing support 6, a valve guide rod 9, a valve guide Rod fixing support 3, valve upper pick connecting rod 10, valve lower pick connecting rod 11, valve upper pick plate 13, valve lower pick plate 14, circuit breaker valve opening guide rail 17, limiter 18 and circuit breaker 19; The upper valve insulating plate 1 is fixed on the valve guide rod 9 through the upper insulating plate fixing support 5; the described lower valve insulating plate 2 is fixed on the valve guide rod 9 through the lower insulating plate fixing support 6; the described valve The guide rod 9 is fixed on the switch cabinet through the guide rod fixing support 3 of the valve; one end of the connecting rod 10 on the valve is fixed on the insulating p...

[0024] The difference between this example and Embodiment 1 is that the switchgear valve opening and closing device also includes a valve upper pick plate 13, a valve lower pick plate 14, a valve torsion spring 15, a valve nylon sleeve 16 and a valve clamp support 12. The valve torsion spring 15 is set in the middle of the valve upper pick-up plate 13 and the valve lower pick-up plate 14; the valve nylon sleeve 16 is set on the valve upper pick-up plate 13 and the valve lower pick-up plate 14, so that the valve nylon sleeve 16 is in the open circuit Slide on the valve opening guide rail 17; the valve clamp support 12 is arranged on the upper pick plate 13 of the valve and the lower pick plate 14 of the valve, and is used to connect the upper pick plate 13 and the lower pick plate 14 of the valve, so that the upper pick plate 13 of the valve The lower pick plate 14 of the valve rotates around the central point under the action of the valve torsion spring 15; the valve clip suppo...

[0026] The difference between this example and Embodiment 1 is that the switch cabinet valve opening and closing device also includes a guide rail mounting support 4, a left valve clamp 7, a right valve clamp 8, and the left valve clamp 7 and the right valve clamp 8 It is fixed on the switch cabinet through the guide rail mounting bracket 4.

[0027] Working principle: When the circuit breaker 19 is shaken with a crank, when the valve is from open to closed, the circuit breaker 19 slowly moves forward, and the circuit breaker valve opening guide rail 17 slowly touches the valve nylon sleeve 16, and the valve nylon sleeve 16 is pressed deeply by the opening guide rail 17 of the circuit breaker valve, and the valve nylon sleeve 16 in contact with the valve upper pick plate 13 is pressed down, and the entire valve upper pick plate 13 takes the fixed center as the center of the circle under the action of the valve torsion spring 15, Take the center distance from the fixed center t...
