The invention relates to the field of high-
voltage switches of power systems, in particular to a super-quick
vacuum switch device. The super-quick
vacuum switch device comprises two to four super-quick
vacuum switch modules which are connected in series; a first operating mechanism and a second operating mechanism of each super-quick vacuum switch module are respectively positioned below a first
epoxy embedded vacuum pole and a second
epoxy embedded vacuum pole; a first
voltage equalizing device and a second
voltage equalizing device are respectively connected in parallel with the first
epoxy embedded vacuum pole and the second epoxy embedded vacuum pole; a
pulse current generator is connected with each of the first operating mechanism and a second operating mechanism; an isolation auxiliary power supply outputs a first direct-
current voltage to provide power for a quick switch controller, and outputs a second direct-
current voltage to provide charging voltage for the
pulse current generator; the quick switch controller is connected with the
pulse current generator; the quick switch controller is communicated with a direct-current
circuit breaker control device positioned at ground potential through an
optical fiber. The switch device is light in moving
mass, quick in response and simple in structure, and facilitates module
cascade extension.
