Directly, the other end has the connecting end surface 31 of outward flanging, and this connecting end surface 31 is vertical with cylinder center axle.Interior air cylinder 3 in-flanges
Outer face be connected with dynamic main contact 19 bolt 32, interior air cylinder 3 is co-axially mounted with dynamic main contact 19.Interior air cylinder 3 is for leading
Electric metal manufactures.
Piston rod 5 is arranged on the installing hole 23 of dynamic main contact 19, and piston rod 5 is thin metallic tubd, and piston rod 5 one end has
One section of external screw thread and one section of female thread, external screw thread is used for and moves main contact 19 installing hole connecting, and female thread is with moving arcing contact 20 even
Connect.The afterbody of piston rod 5 is provided with steam vent 13, piston rod 5 high-strength metal material processing and manufacturing.The length of piston rod 5
Exceed well over the length of interior air cylinder 3.Piston 4 is column structure, and piston rod 5 slides in the centre pilot hole of piston 4, piston 4
One end is flanging structure, and the external diameter of flanging is matched in clearance with the internal diameter of interior air cylinder 3, and piston 4 other end is by living
Plug valve sheet is fixed on interior air cylinder 3.The connecting end surface 31 of interior air cylinder 3 is provided with the piston valve 6 of circular ring structure, this piston
Valve block 6 screw 32 is fixed on interior air cylinder 3, and piston valve 6 external diameter is more than interior air cylinder much smaller than the internal diameter of outer air cylinder 7
The internal diameter of 3, the internal diameter of piston valve 6 is matched in clearance with the external diameter of piston 4.
The periphery of above-mentioned interior air cylinder 3 is further fitted with outer air cylinder 7, the flanging external diameter of interior air cylinder 3 and external pressure
The internal diameter of cylinder 7 is matched in clearance.Outer air cylinder 7 is thin-wall tubular structure, and outer air cylinder 7 is conductive metallic material manufacture.In
The flanging of air cylinder 3 prolongs face and installs conductive contact 39, conductive contact 39 and the sliding contact of outer air cylinder 7, and conductive contact 39 is
The metal ring of helical structure.Outer air cylinder 7 has a flanging end face, and this flanging end face screw is connected to installation end
Face.Even fracture electric field and the uniform shielding 45 to earth electric field are installed outside outer air cylinder 7.
In the periphery of piston rod 5, check valve 9 is installed, this check valve 9 and interior air cylinder 3, piston 4, and piston rod 5 structure
The first above-mentioned plenum chamber 1, piston valve 6, outer air cylinder 7 and piston is become to constitute the second above-mentioned plenum chamber.Above-mentioned check valve

And form balance air chamber 41 between interior air cylinder 3 and piston valve 6.The second gas stream is offered further on above-mentioned interior air cylinder
Circulation passage 42, this second air ventilation passage 42 connects with described balance air chamber 41.
When arc-chutes move to separating brake direction, the first plenum chamber 1 body being made up of interior air cylinder 3, piston 4, piston rod 5
Amassing and reduce, the second plenum chamber 2 volume being simultaneously made up of piston valve 6, outer air cylinder 7, piston 4 is according to the first plenum chamber 1
Compression speed geometric ratio is compressed.Fig. 5 is shown in structural representation.
When, after the second plenum chamber 2 mechanical compress, its internal gas is increased pressure by volume-diminished, this pressure passes through second
Gas boosting in the first plenum chamber 1 given by air ventilation passage 8 and check valve 9, and the gas in the first plenum chamber 1 is by the second plenum chamber
2 and mechanical movement own combine compression, combined the gas of compression by steam vent 24, in the venturi to spout 27 (i.e. first
Air ventilation passage 25) electric arc 12 cools down.Fig. 6 is shown in structural representation.
Compressed the gas of generation after by electric arc 12 by the first plenum chamber 1 and the second plenum chamber 2, become high-temperature gas,
This high-temperature gas is drained by the exhaust passage 13 of spout 27 and piston rod 5 again, thus electric arc is carried out air-borne fungi.Structure is shown
Suggestion Fig. 7.
During sub-switching operation, owing to the contact circular arc of sound main contact and the contact arc size of sound arcing contact are poor
Different, main contact first departs from, and arcing contact also without departing from, now electric current by main contact connect galvanic circle transfer to arcing contact
On link circuit.Continuing under separating brake, arcing contact departs from, and fracture forms voltage, forms electric arc 12 on arcing contact.As shown in Figure 8.
During sub-switching operation, piston valve 6 rearward movement in the second plenum chamber 2, compresses the air chamber of the second plenum chamber 2
Volume, the second plenum chamber 2 pressure raises, opens inside the inside air cylinder 3 of reversing valve 9, is arranged on the reversing valve installed on end face
40 close, and the gas in the second plenum chamber 2 enters in the first plenum chamber 1 by reversing valve 9, and the first plenum chamber 1 is at separating brake simultaneously
Under action, volume also decreases, and the first plenum chamber 1 is in machinery and the dual function therapeutic method to keep the adverse QI flowing downwards of the gas pressure of the second plenum chamber 2
Body blows to spout by steam vent 24.Environmental gas flows into balance air chamber 41 by the second air ventilation passage 42 simultaneously, prevents
Extra air-pressure damping mechanical power only occurs.As shown in Figure 9.
During closing operation, the first plenum chamber 1 and the second plenum chamber 2 expand simultaneously, and reversing valve 9 is to the second plenum chamber 2
Lateral movement is closed, and reversing valve 40 is opened to the second plenum chamber cylinder 2 lateral movement, and environmental gas passes through spout venturi and the second gas
Circulation passage 42 enters the first plenum chamber 1 and the second plenum chamber 2.The gas of balance air chamber 41 passes through steam vent 24 outwardly,
Reduce gas to mechanically operated resistance.
Piston valve 6 is that the piston sheet of more than two panels or two panels assemblies, and anchors till piston valve and fitting surface 32
Position, fixes with screw 32 simultaneously.Structure is shown in Figure 10 to Figure 11.
Dynamic side assemble sequence is that piston system has first assembled, and piston system loads in piston 4, and half point state installs piston
Valve block 6, then the structure of installation is screwed on installed surface, then pushing outer air cylinder 7, outer air cylinder 7 uses spiral shell
Nail is fixed on installation end face.After outer air cylinder 7 has assembled, loading shielding 45, shielding 45 is screwed air cylinder 7 outside
Assembly flange face on.As shown in figure 12.
