Abstract

The invention discloses a self-energy type sulfur hexafluoride circuit breaker. The circuit breaker comprises a supporting shell. Porcelain pillar type arc extinguishing chambers are arranged above the supporting shell. The three porcelain pillar type arc extinguishing chambers are distributed in sequence. A mechanism box is arranged in the middle of a lower portion of the supporting shell. Fixingplates are installed on two sides of the mechanism box. A first supporting rod is arranged below the fixed plates. A first fixing pedestal is arranged below the first supporting rod, a second supporting rod is arranged on one side of the first supporting rod, a second fixing pedestal is arranged below the second supporting rod, the first supporting rod and the second supporting rod are connectedthrough a connecting rod, and a porcelain bushing is arranged on the porcelain pillar type arc extinguishing chambers. By using the self-energy type sulfur hexafluoride circuit breaker, supporting balance performance is good, an on and off effect is ideal and an arc extinguishing speed is fast.

Description

technical field [0001] The invention relates to the technical field of a self-energized sulfur hexafluoride circuit breaker, in particular to a self-energized sulfur hexafluoride circuit breaker. Background technique [0002] Sulfur hexafluoride circuit breaker is a circuit breaker that uses sulfur hexafluoride gas as the arc extinguishing medium and insulating medium, referred to as SF6 circuit breaker. The use of sulfur hexafluoride as an arc extinguishing medium in circuit breakers began in the early 1950s. Due to the excellent characteristics of this gas, the voltage and current parameters of this circuit breaker are much higher than those of compressed air circuit breakers and oil-less circuit breakers, and do not require high air pressure and a considerable number of serial breaks. In the 1960s and 1970s, sulfur hexafluoride circuit breakers have been widely used in ultra-high voltage and large-capacity power systems. In the early 1980s, SF6 circuit breakers with 363...
