| description | The invention provides a cable chamber door interlocking structure of an upper three-station ring main unit, which comprises a grounding interlocking mechanism provided with a grounding interlocking stop dog and a circuit breaker interlocking mechanism provided with a circuit breaker interlocking stop dog, and is characterized in that a first transmission mechanism is arranged between the grounding interlocking stop dog and a three-station isolating switch operating mechanism; the unlocking position corresponds to the grounding state of the three-position isolating switch operating mechanism, and the locking position corresponds to the isolating opening state and the isolating closing state of the three-position isolating switch operating mechanism. A second transmission mechanism is arranged between the circuit breaker interlocking stop block and the circuit breaker operating mechanism, and is used for enabling the circuit breaker interlocking stop block to have an unlocking position corresponding to the swi |
