Embodiment Construction

[0013] The high-voltage vacuum circuit breaker in the present invention relates to internal insulation between the high-voltage vacuum interrupter and the tank, high-current vacuum breaking, rated current and temperature rise, mechanical characteristics, insulation of the outer shell of the vacuum interrupter, and capacitive current breaking , small inductive current breaking and many other existing technical fields.

[0014] Main structure of the present invention is as follows:

[0015] The difference between the structure of the present invention and the current combined electrical appliances is that a vacuum interrupter is used, and the double fracture type makes the rated voltage reach 145kV or 126kV. Each phase adopts the 84KV vacuum interrupter produced by "Toshiba" The room is equipped with a voltage equalizing capacitor, the arc extinguishing room and the tank are insulated by dry air, and the circuit breaker is equipped with a spring operating mechanism. The bushing...

Abstract

The invention relates to an environment friendly outdoor AC high voltage full-sealed combined electric apparatus which uses environmental friendly gases to replace the gas of SF6 for solving the problem of a poisonous low fluorin compound generated by the gas of SF6 used for arc extinguishing. A double-fracture type vacuum arc extinguishing chamber is adopted for arc extinguishing; a compound insulating bushing is arranged at the two sides of the arc extinguishing chamber; a three-power position isolating switch is arranged in the lower surface; the lower part of the bushing is sheathed with an electromagnetic mutual inductor or a photoelectric mutual inductor; high pure nitrogen is filled in the bushing and a tank body for internal isolation; the high pure nitrogen is adopted between the vacuum arc extinguishing chamber and the tank body for internal isolation; the fracture of each double-fracture type vacuum arc extinguishing chamber is provided with an equalizing capacitor; the three-power position isolating switch adopts the high pure nitrogen as the internal isolation, thus shortening the mounting time and improving the reliability and safety of the device. The environment pollution is avoided in particular as the gas of SF6 is not used.

Description

Technical field: [0001] The invention relates to the technical field of high-voltage electrical appliances, in particular it is an environment-friendly outdoor AC high-voltage fully enclosed combined electrical appliance. Background technique: [0002] High-voltage combined electrical appliances and high-voltage circuit breakers are commonly used electrical appliances in high-voltage electrical appliances. At present, the high-voltage combined electrical appliances and high-voltage circuit breakers used in domestic and foreign power grids are filled with SF6 gas of about 0.5Mpa. A strong greenhouse effect gas: Among the six greenhouse effect gases specified in the "Kyoto Protocol" passed in 1997, SF6 gas is the strongest greenhouse effect, and its global warming coefficient is 23900 times that of CO2. Its lifetime in the atmosphere is 3200 years, so limiting the use of SF6 gas is an inevitable trend. SF6 gas is mainly used in switchgear and power transmission and transform...
