Embodiment 1

[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...

Embodiment 2

[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...

Embodiment 3

[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...

Abstract

The invention discloses a switch cabinet valve opening and closing device, which has the advantages that the structure is reasonable; the mounting is quick; opening and closing of the valve are flexible; a circuit breaker handcart is not clamped; and a transmission part and a valve structure part of the handcart are not damaged. The switch cabinet valve opening and closing device comprises an upper valve insulation plate, a lower valve insulation plate, a valve guide rod, a valve upper picking connection rod, a valve lower picking connection rod, a valve upper picking plate, a valve lower picking plate and a limiting piece. By adopting the device of the invention, when the circuit breaker is at an experiment position, the valve is closed, and thus, safety and insulation effects are realized; and during a process during which the circuit breaker moves to a working position from the experiment position, the valve can be opened smoothly, moving and working of the circuit breaker are not influenced, and the safety and the reliability of the switch cabinet are improved.

Description

technical field [0001] The invention relates to a high-voltage switchgear for power distribution, in particular to a valve opening and closing device suitable for the switchgear. Background technique [0002] In the whole high-voltage electrical system, the safety issue is a key issue, because it is related to the safety and interests of the electric unit and the individual during the use of the switchgear; so the safety issue cannot be ignored. When the system is electrified and the circuit breaker is in the experimental position, the static contacts inside the contact box are electrified. If no safety measures are taken, there will be potential safety hazards and accidents are likely to occur; and this practice does not meet the requirements of the five defenses. [0003] As an important part of the switchgear, the valve mechanism is one of the indicators to measure the performance of the switchgear whether the valve can be opened or closed smoothly when entering the worki...
