Embodiment
The utility model is described in further detail below by specific embodiment and with reference to accompanying drawing.
Embodiment 1
As shown in figure 1, a kind of device of pressure control breaker break-make, include the arc-chutes 1 of tubular, the arc-chutes 1
A static contact 2 is fixed with the inside of one end, the other end offers a port 3, a relay piston is provided with described arc-chutes 1
4, the inwall of described relay piston 4 and arc-chutes 1 is sealed against each other, and the side of relay piston 4 towards the static contact 2 is fixed with
One moving contact 5, the arc-chutes 1 are fixed with a first annular gear for preventing relay piston 4 from skidding off arc-chutes 1 in the position of port 3
Circle 6, described arc-chutes 1 are provided with a driving cylinder 7, described driving on the arc-chutes 1 between moving contact 5 and static contact 2
Cylinder 7 is connected with arc-chutes 1, and an active piston 8, described active piston 8 and driving cylinder 7 are provided with described driving cylinder 7
Inwall seal against each other, the bottom of the driving cylinder 7, which is fixed with one, prevents active piston 8 from skidding off the second ring of driving cylinder 7 bottom
Shape back-up ring 9, the top of the driving cylinder 7 are connected by tracheae 10 with an air pump 11, described active piston 8, the and of relay piston 4
The filled chamber for filling arc extinguishing gases is formed between arc-chutes 1, arc extinguishing gases are filled with described filled chamber.
The barometer 12 of air pressure in a monitoring driving cylinder 7 is fixed with driving cylinder 7, barometer 12 being capable of real-time display driving
Air pressure in cylinder 7, the clutch situation of moving contact 5 and static contact 2, convenient maintenance, described tracheae are can interpolate that according to the air pressure
A valve is in series with 10, when needing holding moving contact 5 to be closed with static contact 2 or off-state, valve is closed, needed
When changing the closure or off-state of moving contact 5 and static contact 2, valve is opened, is easy to the air-breathing of air pump 11 or inflation, described goes out
A check valve that arc extinguishing gases are filled with into filled chamber is provided with arc chamber 1, is added, drives when filling indoor gas is less
Dynamic cylinder 7 is mutually perpendicular to fix with arc-chutes 1.
The utility model controls gas when controlling moving contact 5 to realize that moving contact 5 and static contact 2 close to static contact 2 is close
Pump 11 suctions out the gas in driving cylinder 7, now, drives the air pressure in cylinder 7 to be less than the air pressure in filled chamber, active piston 8 is upward
Slide, with the upward sliding of active piston 8, the air pressure in filled chamber reduces, because the air pressure in filled chamber is less than outside port 3
Atmospheric pressure, relay piston 4 slide in the presence of external atmosphere pressure to the one end of static contact 2, until moving contact 5 closes with static contact 2
Close, now, external atmosphere pressure is more than the air pressure in filled chamber, and such external atmosphere pressure just tightly pushes down moving contact 5 so that dynamic
Together with contact 5 is closely pressed together on static contact 2；Realize that moving contact 5 and static contact 2 disconnect away from static contact 2 in control moving contact 5
When, control air pump 11 is filled with gas into driving cylinder 7, now, drives the air pressure in cylinder 7 to be more than the air pressure in filled chamber, actively
The slide downward of piston 8, with the slide downward of active piston 8, the air pressure in filled chamber gradually rises, when the air pressure in filled chamber is big
When atmospheric pressure outside port 3, relay piston 4 slides to port one end, until relay piston 4 offsets with first annular back-up ring 6,
Now, moving contact 5 is separated from each other with static contact 2.
