The gas ring main unit is a switch device advocated by the state. The gas ring main unit is provided with an isolating switch and a breaker, wherein the isolating switch is provided with three stations of conduction, isolation and grounding, so that the gas ring main unit is also called a three-station isolating switch. In the prior art, an isolating switch mounting plate and a breaker mounting plate are arranged in a ring main unit, a breaker operating mechanism and a three-station isolating switch operating mechanism are respectively arranged on the breaker mounting plate and the three-station isolating switch mounting plate, isolating grounding operation holes and isolating conduction operation holes corresponding to corresponding operation shafts of the three-station isolating switch operating mechanism are arranged on the three-station isolating switch mounting plate at intervals, and when the three-station isolating switch is operated, the three-station isolating switch can be isolated to ground or isolated to conduction by penetrating an operation handle in the corresponding operation holes. The breaker mounting plate is also generally provided with a manual operation closing button capable of controlling the breaker operating mechanism to close, the closing button is pressed, an operating shaft of the breaker operating mechanism rotates, and the breaker operating mechanism drives the breaker to close.
Since the three-position disconnecting switch cannot be opened under the load condition due to the characteristics of the three-position disconnecting switch, the three-position disconnecting switch and the circuit breaker must be operated according to a fixed operation sequence. When the three-position isolating switch is operated, the circuit breaker must be in a switching-off state, and when the circuit breaker is in a switching-on state, an operator cannot operate the three-position isolating switch. And the operator cannot operate the breaker to close when operating the three-position disconnecting switch, therefore, an interlocking device must be arranged between the three-position disconnecting switch and the breaker to prevent misoperation.
The integrated operating mechanism of the disconnecting switch and the vacuum switch disclosed in the Chinese patent publication No. CN205354916U comprises an interlocking slide plate and an interlocking baffle plate, wherein the interlocking slide plate can move up and down, namely a button locking structure for locking or unlocking a closing button of a circuit breaker is used, the interlocking slide plate is in transmission connection with a cam of the disconnecting switch, when the disconnecting switch is opened, the cam of the disconnecting switch drives the interlocking slide plate to move downwards so that a blocking block on the interlocking slide plate moves to the rear of the closing button of the circuit breaker to lock the closing button, and when the disconnecting switch is closed, the cam of the disconnecting switch reversely rotates the interlocking slide plate to move upwards so that the blocking block on the interlocking slide plate is unlocked from the closing button. The interlocking baffle shields the disconnecting switch operation hole and the grounding switch operation hole when the circuit breaker is closed, and gives way to open the disconnecting switch operation hole and the grounding switch operation hole when the circuit breaker is opened, and the interlocking baffle is connected with the crank arm piece on the circuit breaker operation main shaft.
The integrated operating mechanism can realize interlocking control between the circuit breaker and the isolating switch as well as between the circuit breaker and the grounding switch, but because the interlocking slide plate is in transmission connection with the isolating switch cam, the load capacity of the operating rotating shaft of the isolating switch is increased, and the structure of the mechanism is complex due to the transmission structure arranged between the interlocking slide plate and the isolating switch cam. Meanwhile, the interlocking slide plate can only realize interlocking control with the isolating switch, and cannot realize interlocking control with the grounding switch, namely, the interlocking slide plate cannot lock the switching button when the grounding switch is operated, and an interlocking leak exists.
