Patent JP-H03241626-A (JP)
Title: Circuit-breaker
Inventor: ITO SHUNJI
IPC: H01H33/70
Filed: 1990-02-19
Abstract: PURPOSE:To improve shutting function by low operating force by spraying a fluid to an arc, which fluid is in a storage chamber and heated by arc heat to rise in pressure, heightening the spraying power by sucking the sprayed fluid, and compressing the fluid so further as to spray it to the arc. CONSTITUTION:When a movable contactor 2 starts to work and separats from a fixed contactor 1, an arc is generated between the contactors 1, 2 and pressure of a storage chamber 3 is risen. A pressured fluid in the chamber 3 starts to be sprayed to an arc at the time when an insulating nozzle 6 leaves the contactor 2. At that time, a negative pressure chamber 17 become negative pressure owing to the sliding between a piston 8 and a cylinder 7 and when the piston 8 passes the gas discharge hole 19 in the cylinder 7, the fluid sprayed from the nozzle 6 is sucked. After that, the sprayed fluid is sprayed to the arc through a hole 16 formed in the contactor 2 by sliding a pistone 9 and the cylinder 12. Consequently, the arc can effectively be put out by low operating force.
