Abstract
HVDC is in sealing contact device moving contact structure, mainly including the first moving contacting plate, movable contact, lining on first, electromagnetic driving system, lining, the first touch spring and backup washer on second, each part is sequentially connected with by riveting and securing member and corresponding fixing hole；This structure of contact terminal uses two-way double-breakpoint structure, also includes second moving contacting plate being located at below the first moving contacting plate, a support adjusting washer (disk) being located on the second moving contacting plate and second touch spring 1 being located at outside the first touch spring；Described first moving contacting plate and the second moving contacting plate are double " J " shape.The present invention uses " J " shape structure design of double moving contacting plate to accelerate motion and the extinguishing of electric arc when contact disconnects, and reduces the loss to contact；Use moving contacting plate and touch spring structure effectively to reduce effective regulation of the arc time between main contacts, the abrasion of contact and contact force, make four breakpoints can effectively contact and disconnect, thus improve product usefulness and life-span.
Description
Technical field
The present invention relates to a kind of HVDC and be in sealing contact device moving contact structure, for aircraft power system loop break-make,
Control load and be applicable to (1000A～3000A) × (270～1000) VDC.
Technical background
Existing HVDC is in sealing contact device moving contact as it is shown in figure 1, mainly include moving contacting plate, upper lining, lower lining
Set and touch spring, when disconnecting high-voltage great-current, its defect is: (1) in " one " font and quantity is one due to moving contacting plate
Individual, the arc time between main contacts is longer, and the abrasion of contact is bigger；(2) being one due to touch spring quantity, the life-span is disconnected and very
Difficult disconnection.
Summary of the invention
To be solved by this invention when being break-make high-voltage great-current: the arc time between catalyst main contacts is longer, contact
Abrasion bigger；The technical problem that arc extinguishing ability is low and the life-span is short.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that
HVDC is in sealing contact device moving contact structure, mainly includes lining 4 on the first moving contacting plate 1, movable contact 2, first, electricity
Lining the 6, first touch spring 7 and backup washer 8 in Magnetic driving system 5, second, each part is solid by riveting and securing member and correspondence
Determine hole to be sequentially connected with；It is characterized in that: this structure of contact terminal uses two-way double-breakpoint structure, also include one and be located at first and dynamic connect
The second moving contacting plate 9 below contact 1, a support adjusting washer (disk) being located on the second moving contacting plate 93 and one are located at first
The second touch spring 1 outside touch spring 7；Described first moving contacting plate 1 and the second moving contacting plate 9 are in double " J " shape.
Technique scheme is used to provide the benefit that:
1, the present invention uses double touch spring and supports the design of adjusting washer (disk) structure so that four breaking points can effectively contact,
The contact force of respective contact can be automatically adjusted so that each contact can effectively contact simultaneously, can disconnect in small size sealing
Big electric current and big voltage；
2, the present invention uses " J " shape structure design of double moving contacting plate, can accelerate motion and the extinguishing of electric arc when contact disconnects,
Reduce the loss to contact；
3, due to the fact that the arcing that have employed between rational moving contacting plate and the design of touch spring structure, effectively minimizing main contacts
Effective regulation of time, the abrasion of contact and contact force, makes four breakpoints can effectively contact and disconnect, thus improves product
Usefulness and life-span；
4, volume of the present invention is little, easy for installation, safe and reliable, belongs to economic and practical type product.

Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further detail:
As it is shown on figure 3, HVDC is in sealing contact device moving contact structure, mainly include the first moving contacting plate 1, movable contact 2, first
Lining the 6, first touch spring 7 and backup washer 8 on upper lining 4, electromagnetic driving system 5, second, each part is by riveting and fastening
Part and corresponding fixing hole are sequentially connected with；This structure of contact terminal uses two-way double-breakpoint structure, also includes one and is located at first and dynamic connects
The second moving contacting plate 9 below contact 1, a support adjusting washer (disk) being located on the second moving contacting plate 93 and one are located at first
The second touch spring 1 outside touch spring 7；Described first moving contacting plate 1 and the second moving contacting plate 9 are " J " shaped.
Described first moving contacting plate 1 and the second moving contacting plate 9 form an assembly by support adjusting washer (disk) 3 and drive at electromagnetism
Dynamic system has identical kinestate and respective regulation energy for 5 times.
The structure of described first moving contacting plate 1 and the second moving contacting plate 9 can accelerate arc extinction, thus increases catalyst
Arc extinguishing ability.
The key technical indexes of the present invention:
A) main contacts voltage: 270～1000V DC；
B) main contacts electric current: (1000～3000) A；
C) job specification: continuously.
