Abstract
The utility model relates to an extra-high voltage porcelain knob type SF6 breaker of 1100kV. The central axes of arc extinguish chambers and an equalizing capacitor form a definite included angle with the horizontal plane. The number of insulating stand bodies is two, and the number of the arc extinguish chambers is four. Each arc extinguish chamber is also connected in parallel with a switching-on resister horizontally arranged. The switching-on resisters and the arc extinguish chambers are matched and connected with a fracture operation mechanism. The upper part of each insulating stand body is provided with three insulating derrick braces circumferentially and evenly arranged. Because the voltage class of the arc extinguish chambers is improved, and the switching-on resisters are arranged below the arc extinguish chamber and the equalizing capacitor, the utility model has the advantages of simple structure, reliable quality, easy manufacture, convenient product installation and maintenance and low product cost. Meanwhile, the uneven distribution coefficient of fracture voltage is less than 1.04. The anti-seismic performance is largely improved, so the utility model can be used for area where earthquake intensity is 8 degrees, and has a wider application range.
