Background technology
It is always sulfur hexafluoride in ultra-high pressure switch appliance field（SF6）Electric appliance rules all the land, this kind of device for switching structure
Complexity, it is bulky, need frequent periodic inspection；Wherein SF6 gases have good electric property as insulation and arc-extinguishing medium
, itself is non-toxic, but passes through device for switching closing and cut-off repeatedly, and SF6 gases are generated other by the calcination of electric arc
Decomposition product or compound, combined with hydrogen in moisture and generate corrosive substance hydrogen fluoride, these substances are most of to personnel, to ring
Border is all influential.In addition, sulfur hexafluoride（SF6）Gas is one of presently found six kinds of greenhouse gases.In High-Voltage Electrical Appliances
Manufacturing uses a large amount of SF6 gases, due to the use of, mismanagement or it is not recycled by correct method,
Regeneration treatment causes SF6 gases and the toxic breakdown object generated under high-temperature electric arc effect to be discharged into air, relies to the mankind
The environment of existence brings pollution and destruction, while normal operation to electrical equipment and people's health bring adverse effect.
Invention content
The purpose of the present invention is utilizing vacuum extinction principle, by rationally designing and making, ultra-high pressure switch electricity is solved
Device eliminates the reliance on SF6 gases as insulation and arc-extinguishing medium, while simplifying device for switching structure, reduces material consumption and processing charges
With, make ultra-high pressure switch electric appliance realize vacuum miniaturization, non-maintaining, non-environmental-pollution.

Specific production method：In Fig. 1, cylindrical dielectric shell 5 welds together with round end cap 1, forms annular
Seal-weld 4；2 upper end of static contact conducting rod is pierced by round end cap 1, and welds together, and forms ring packing weld seam 4；Stationary contact
2 upper end of head conducting rod is equipped with connection terminal 3, to be connect with external electrical；5 outside of cylindrical dielectric shell is equipped with cyclic annular small full skirt
51, cyclic annular big full skirt 52；Static contact conducting rod 2 and cup-shaped press shielding case 7, static contact 8, are assembled by connector 6
Together；Moving contact 9 links together with upper pallet 10, and upper pallet 10 is connected with telescopic arm 11 by connecting shaft 12 again, with circle
5 lower end sealing welding of column insulation crust forms ring packing weld seam 13；Sleeve-board weldering 15 is installed to weld with metal cylinder 14, is formed
Annular attachment weld 16；11 lower part of telescopic arm is linked together by fixed support shaft 25 with metal cylinder 14；11 lower end of telescopic arm
It is connected with lower pallet 17 and 19 upper end of moving conductive rod；19 middle part of moving conductive rod and 23 sealing welding of Telescopic metal bellows, shape
At annular seal-weld 18,19 lower end of moving conductive rod is equipped with operating mechanism connection terminal 20, to be connect with external manipulation mechanism；
22 lower end of conducting block is equipped with connecting terminal, to be connect with external miscellaneous equipment；To constitute the cavity body structure of a sealing, then pass through
Encapsulation process is vacuumized, vacuum chamber 24 is formed, the electric arc that the switch closing and switch opening of moving contact 9 generates extinguishes in vacuum chamber, from
And constitute a complete ultrahigh voltage vacuum arc-chute.
The operating principle of the present invention：
Making process：From illustrating 2 gate-dividing state of attached drawing to the process for illustrating that attached drawing 1 is converted, i.e., by operating mechanism connecting pin
Son 20 pulls downward on, and lower pallet 17 is transmitted to by conducting rod, and lower pallet 17 drives 11 lower end of telescopic arm to move downward again, due to
11 lower end of the telescopic arm axis 25 that is fixedly supported is fixed on the both sides of metal cylinder 14, so the top of telescopic arm 11 pushes away round about
Dynamic upper pallet 10 and moving contact 9 are moved to static contact 8, and final moving contact 9, static contact 8 are closed together, as illustrated 1 institute of attached drawing
Show that completion is closed a floodgate.
Making process：From illustrating 2 gate-dividing state of attached drawing to the process for illustrating that attached drawing 1 is converted, i.e., by operating mechanism connecting pin
Son 20 pulls downward on, and lower pallet 17 is transmitted to by conducting rod, and lower pallet 17 drives 11 lower end of telescopic arm to move downward again, due to
