Thaum lub load capacitance qis dua 3000PF, qhov voltage siv coefficient ntawmtus qauv xob laim yog ntau dua lossis sib npaug li 85%, thiab qhov voltage siv coefficient ntawm tus qauv kev khiav hauj lwm impulse voltage tag nrho nthwv dej yogNtau dua lossis sib npaug li 75%.
4 Lub sijhawm ua haujlwm
Nyob rau hauv 2/3 rated voltage saum toj no, txhua txhua 120 vib nas this them thiab tawm ib zaug, tuaj yeem khiav tsis tu ncua.Raws li 2/3 rated voltage, them thiab tawm txhua 60 vib nas this, tuaj yeem khiav tsis tu ncua.
5 Kev tswj qhov chaw:
Kev tuav tswj, kev them nyiaj tam sim no tsis tu ncua, tsis ruaj khov ntawm kev them nqi hluav taws xob tsis pub ntau tshaj ± 1%, kev sib txawv ntawm kev them nqi hluav taws xob thiab siv hluav taws xob tsis tshaj ± 1%, kho qhov tseeb ntawm kev them hluav taws xob yog ± 1%.
Khoom Description
Lub hauv paus ntsiab lus ntawm daim duab kos duab ntawm lub impulse voltage generator lub cev yog qhia hauv daim duab 1.
FIG. 1 Schematic daim duab ntawm impulse voltage generator lub cev
Lub impulse voltage generator yog them nyob rau hauv ib tug asymmetric voltage ob npaug rau hom, thiab lub siab tshaj plaws them voltage ntawmtxhua theem yog 200 kV.Lub ntsiab qauv yog insulated pillar ntauwd hom, txhua theem muaj ob lub bushing (los yog ob lub bushing) hlau plhaub mem tes capacitor, ib khub ntawm ignition pob sib txawv, lub taub hau nthwv dej (los yog damping) tsis kam, yoj tus Tsov tus tw, kev them nyiaj.
Txhua theem ntawm lub cevmuaj tsib tus ncej insulating, ntawm uas plaub coarse insulating pillars yog siv los txhawb lub mem tes capacitor.carry yoj lub taub hau (los yog damping) tsis kam, yoj tus Tsov tus tw tsis kam, them tsis kam. Ib lub thoob zoo li tus ncej insulated feem ntau txhawb nqa qhov sib txawv ntawm 200mm ignition ball.Peb cov qauv hluav taws xob thiab kab rov tav kab rov tav tau txais kev pom zoo rau txhua khub ntawm qhov sib txawv ntawm qhov sib txawv.Lub pob qhov sib txawv yog kho nyob rau hauv txoj kab ncaj nraim uas tau tsav los ntawm lub cev muaj zog, thiab qhov sib thooj pob qhov sib txawv yog qhia rau ntawm lub console los ntawm qhov taw tes. thiab hloov.
Lub cev yog mounted rau ntawm ib tug movable channel steel chassis, uas yuav tsum tau dragged los ntawm ib tug traction pas nrig ntawm yuav. Thaum xob laim impulse voltage nthwv dej(nrog rau tag nrho nthwv dej thiab truncated yoj)yog generated, qhov tsis kam ntawm yoj lub taub hau thiab yoj tus Tsov tus tw yog dispersed mus rau txhua theem, ua ib tug siab - efficiency me me paug Circuit Court.Ob lub yoj lub taub hau resistors thiab ib pawg yoj-tail resistors yuav ua tau raws li qhov yuav tsum tau ntawm load capacitance ntau yam.
Thaum kev khiav hauj lwm impulse voltage nthwv dej yog generated, xob laim yoj lub taub hau resistances ntawm txhua qib yog khaws cia raws li damping resistances ntawm txhua theem. Cov kev khiav hauj lwm yoj tus Tsov tus tw kuj yog dispersed nyob rau hauv tag nrho cov theem, thiab lub clamping tail resistances ntawm tag nrho cov theem thiab kev them nqi kuj yog qhov sib npaug sib npaug yoj tail resistances ntawm kev khiav hauj lwm yoj. Sab nraud yoj lub taub hau tiv thaiv yog txuas ntawm lub cev thiab lub nthwv dej lub taub hau capacitance.Ob lub nthwv dej - lub taub hau resistors thiab ib txheej ntawm nthwv dej -tail resistors tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm kev thauj khoom muaj peev xwm.
Thaum lub oscillating xob laim los yog oscillating ua hauj lwm impulse voltage nthwv dej yog generated, nws damping kuj thiab yoj-tail resistance yog dispersed ntawm cov theem, thaum lub oscillating inductance yog kev cob cog rua ntawm lub cev thiab yoj- lub taub hau capacitance.Ib txheej ntawm oscillating inductance, damping kuj, yoj tus Tsov tus tw kuj muaj peev xwm ua tau raws li qhov yuav tsum tau muaj ntawm yoj. damping resistance (los yog luv-circuit rod) thiab yoj-tail resistance yog dispersed mus rau txhua theem los tsim ib tug ntxhab yoj circuit. Thaum lub steepness yoj tsis ua raws li qhov yuav tsum tau ua, cov cuab yeej steepening tuaj yeem siv tau.Ib txheej ntawm damping tsis kam (los yog luv luv Circuit Court bar), yoj tus Tsov tus tw kuj tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm qhov kev sim siab yoj.
