A modified large nozzle high pressure switch sf6 circuit breaker

Abstract

The invention discloses a modified SF6 circuit breaker with a large nozzle high-voltage switch, which includes a circuit breaker box, an intermediate contact finger is installed at the lower left corner of the circuit breaker box, and a cylinder is installed at the end of the intermediate contact finger. A piston is installed on the lower right side, a moving main contact is installed on the upper right of the cylinder, a spring is installed on the outside of the moving main contact, a smooth surface is connected to the spring, and a large Nozzle, the inside of the large nozzle is filled with filling material, a moving arc contact is installed on the right side of the piston, an arc is installed on the top of the moving arc contact, and a static arc contact is installed above the arc, A static main contact is installed above the circuit breaker box. The modified large nozzle high-voltage switch SF6 circuit breaker has improved the insulation, corrosion resistance, and high-current breakdown resistance of the large nozzle by setting a smooth surface and matching filling materials, which is more conducive to the popularization and use of circuit breakers. .

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a modified large-nozzle high-voltage switch SF6 circuit breaker. Background technique [0002] The high-voltage switch SF6 circuit breaker is also called the spout, and it is widely used in daily life. The high-voltage switch SF6 circuit breakers currently on the market are generally of unstable quality, and are generally air circuit breakers or oil-immersed circuit breakers with poor reliability. Circuit breakers with unstable quality and poor reliability are often buried in circuits in real life. Once an accident occurs, it will cause huge impact and loss on people's production and life. Contents of the invention [0003] In view of the above problems, the present invention provides a modified SF6 circuit breaker with a large nozzle high-voltage switch, which can effectively solve the problems in the background technology by setting smooth surfaces and filling mater...
