Abstract

The invention discloses a three-phase mechanical link connecting mechanism of a breaker, belonging to the technical field of high-voltage switches. The three-phase mechanical link connecting mechanism of the breaker comprises a driving link rod mechanism, a bracket component and single-phase link rod mechanisms, wherein the input end of the driving link rod mechanism is connected with the output end of an operating mechanism, and the output end of the driving link rod mechanism is arranged on the bracket component by means of rotating together with the input ends of the single-phase link rod mechanisms; the output ends of the three single-phase link rod mechanisms are respectively connected with three corresponding input ends of a triple-pole breaker; a torque which is outputted by the operating mechanism is outputted to connecting lever shafts of the three single-phase link rod mechanisms through the driving link rod mechanism, and dynamic contacts of the three-phase breaker are simultaneously moved by the breaker body, therefore, the switching on and off operations of the breaker are realized.

Description

technical field [0001] The invention relates to a device in the technical field of high-voltage switches, in particular to a three-phase mechanical linkage connection mechanism for a circuit breaker. Background technique [0002] At present, most of the 252kvGIS circuit breaker transmissions on the market adopt three-phase independent operating mechanism. For the high-voltage circuit breaker used to protect the transformer, it is required that the circuit breaker must operate three phases simultaneously, that is, three-phase linkage, no matter under any circumstances. The current three-phase linkage methods include electrical linkage, hydraulic linkage and mechanical linkage. Among them, both electrical linkage and hydraulic linkage have certain limitations, which cannot provide higher synchronization of opening and closing, and there are also hidden dangers of non-full-phase operation of circuit breakers. Mechanical linkage can effectively improve these problems. [0003]...
