Abstract
The utility model mainly relates to an electric power feed device under a vacuum condition, belonging to the electric vacuum field. A ceramic-metal sealed high-pressure vacuum wall component comprises an inner conductor (7), wherein two ends of the inner conductor are provided with a cable terminal respectively; and the outside of the inner conductor (7) is provided with an inner ceramic insulating sleeve (6). The ceramic-metal sealed high-pressure vacuum wall component is characterized in that: the outside of the inner ceramic insulating sleeve (6) is provided with an outer conductor large ring (4) and an outer conductor small ring (5) which are in fixed connection; an outer ceramic insulating ring (3) is arranged between the outer conductor large ring (4) and a grounding conductor (2); and a vacuum flange (1) is arranged on an outer ring of the grounding conductor (2), and is connected with the outer ring of the grounding conductor (2). The ceramic-metal sealed high-pressure vacuum wall component has the advantages that: pressure resistance of the wall component is improved; the vacuum leakage rate of the whole ceramic-metal sealed high-pressure vacuum wall component is superior to 1x10<-10> Paxl/s; the actual measurement of an inductance value is 0.08 mu H; a heavy-section conductor structure can bear current in thousands of ampere.
Description
Technical field:
The utility model relates generally to the electrovacuum field, the electrical power feedback people device under vacuum condition.
Background technology:
At present in through walls of electrovacuum field, the device application of transmitting weak current or low voltage signal is extensive, comparative maturity, kind is also a lot, as single core, multicore or the like.Transmit big electric current or high-tension purpose if expectation by the simple amplification to existing device, reaches, relate to a lot of insurmountable technological problemses, infeasible.Therefore developing such device seems very meaningful, solves electrical power feedback people problem big under vacuum condition.
The utility model content:
The purpose of this utility model is to avoid the deficiencies in the prior art part and a kind of through walls of high pressure vacuum of ceramic-metal sealing-in is provided, and has low inductance, high withstand voltage, big electric current, high vacuum, characteristics that volume is little.
The purpose of this utility model can be by realizing by the following technical solutions: through walls of a kind of high pressure vacuum of ceramic-metal sealing-in, include inner wire (7), its two ends are cable termination, the outside is provided with interior ceramic insulation cover (6), its main feature is: be provided with big ring of the outer conductor that is connected mutually (4) and the little ring of outer conductor (5) in the outside of interior ceramic insulation cover (6), ceramic insulation ring (3) outside between big ring of outer conductor (4) and earthing conductor (2), being provided with, vacuum flange (1) is located at the outer shroud of earthing conductor (2), and is attached thereto and connects.
Through walls of the high pressure vacuum of described ceramic-metal sealing-in, described earthing conductor (2), the big ring of outer conductor (4) and the little ring of outer conductor (5) are that an end is the opening on the plane shape of rectifying, opening rectify shape Closed End in one plane.
The beneficial effects of the utility model are: withstand voltage the reaching more than the 60KV between big ring of outer conductor (4) and the little ring of outer conductor (5) and the inner wire (7); Withstand voltage reaching more than the 20KV between vacuum flange (1) and earthing conductor (2) and the big ring of outer conductor (4) and the little ring of outer conductor (5); The vacuum leak rate that the high pressure vacuum of whole ceramic-metal sealing-in is through walls is better than 1 * 10
-10Pal/s; The inductance value actual measurement is 0.08 μ H; Heavy in section conductor structure can carry thousands of amperes electric current.
