Embodiment 1

[0041] Such as Figure 1-21 As shown, a three-station mechanism is installed in an environmentally friendly gas-insulated ring network cabinet. The environmentally friendly gas-insulated ring network cabinet includes a cabinet body 1, a three-station switch 2, a three-station mechanism 3, a circuit breaker main circuit 4 and a circuit breaker Mechanism 5, three-position switch 2, three-position mechanism 3, circuit breaker main circuit 4 and circuit breaker mechanism 5 are installed in the cabinet body 1, and an interlocking device 6 is connected between the three-position mechanism 3 and the circuit breaker mechanism 5. To prevent live operation of the three-position mechanism 3, the three-position switch 2 is connected with an indicating device 9 for displaying the state of the three positions.

[0042] The cabinet body 1 includes a gas box 11, an instrument room 12 and a cabinet frame 13. The cabinet frame 13 is equipped with a mechanism room 131 and a cable room 132. The g...

Abstract

The invention discloses a three-station mechanism which comprises a three-station rack and a cam disc, the cam disc is fixedly arranged on an insulation main shaft of a three-station switch, and an isolation output device, an isolation transmission device, a grounding output device, a grounding transmission device and an energy storage device are installed on the three-station rack. The isolation output device and the grounding output device are respectively linked with the energy storage device and control the energy storage device to store energy, and the isolation transmission device and the grounding transmission device are linked with the cam disc and respectively output switching-on and switching-off torque and grounding torque to the insulation main shaft through the cam disc. The isolation transmission device and the grounding transmission device are designed to drive the cam disc to rotate to output opening and closing torque and grounding torque to the insulation main shaft; the structure is simple, operation is convenient, the transmission efficiency is high, and the three-station mechanism is reasonable and reliable in overall structural design, high in stability and long in service life.

Description

technical field [0001] The invention belongs to the field of environment-friendly gas-insulated ring network cabinets, and relates to a three-station mechanism. Background technique [0002] With the continuous progress and improvement of breaking and insulation technology, the development of environmentally friendly gas-insulated metal-enclosed switchgear has matured in theory and technology. The products produced by domestic equipment manufacturers have passed the type test and are hung on the grid. However, at present Most of the environmentally friendly core components on the market use epoxy resin to wrap the live parts, or use insulating plates to isolate the live parts, so as to achieve the effect of insulation. [0003] The current three-station mechanism usually has complex structure, unstable performance and high manufacturing cost. Therefore, the isolated three-station structure is redesigned to adapt to the environment-friendly gas-insulated ring network cabinet....
