Abstract

The invention discloses a compact longitudinal rotation type isolating switch which comprises a rack and a hollow rotating shaft rotatably connected to the rack, and is characterized in that the hollow rotating shaft is provided with three isolating knives, a circuit breaker is arranged in each isolating knife, elastic calipers for connecting contacts are arranged at two ends of each isolating knife, and a driving block and a connecting rod capable of axially sliding are further arranged in the hollow rotating shaft; the driving block is hinged to the hollow rotating shaft, a first waist-shaped hole and a second waist-shaped hole are formed in the two ends of a hinge point respectively, the circuit breaker is connected to the second waist-shaped hole through a circuit breaker driving pin,and the connecting rod is connected to the first waist-shaped hole through a connecting rod pin. The connecting rod is connected with a connecting rod driving device for driving the connecting rod toaxially move; the hollow rotating shaft is connected with a rotating power device for driving the hollow rotating shaft to rotate. Compared with the prior art, the circuit breaker is integrated in theisolation knife, and the driving block, the connecting rod, an air cylinder and a rotating stop block which are used for driving the circuit breaker to act are also located in the hollow rotating shaft, so that the size of the whole isolating switch is greatly reduced.

Description

technical field [0001] The invention relates to a compact vertical rotary isolating switch, which belongs to the technical field of isolating switches. Background technique [0002] The isolating switch in the prior art adopts a circuit breaker and an isolating knife that are connected in series. When working, the circuit breaker can be opened and closed with load, and the isolating knife is used to realize no-load closing or opening. Since the circuit breaker needs to be equipped with a separate power device to realize its rapid opening and closing, and the isolating knife also needs to reserve a certain space for operation, so the entire isolating switch has a large volume and a relatively complicated structure. In view of this , in the prior art, there is a need for an isolating switch with smaller volume and simpler structure. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a com...
