Description

Technical Field

[0001] The utility model relates to the technical field of isolating switches, in particular to an indoor high-voltage isolating switch. Background Art

[0002] High-voltage disconnectors are important switchgear in the electrical systems of power plants and substations. They need to be used in conjunction with high-voltage circuit breakers. Their main functions are to ensure the safety of high-voltage electrical appliances and devices during maintenance work and to isolate voltage. They cannot be used to cut off or input load current or break short-circuit current. High-voltage disconnectors can be divided into indoor high-voltage disconnectors and outdoor high-voltage disconnectors. The existing publication number is CN216288148U, which is an indoor high-voltage disconnector. The active gear is driven to rotate by a rotating rod, and the active gear drives the screw rod to rotate synchronously through the driven gear. As the screw rod rotates, the thread sleeve moves upward on the screw rod, driving the connecting rod to squeeze the fixed block. The fixed block drives the limit rod to pass through the limit hole to fix the pin in the installation cavity, so that the isolation protective shell can be fixed; however, the above switch operation process is complicated and not conducive to use.
