Lub hauv paus ntsiab lus ntawm high-power tswj fais fab mov
Lub zog hluav taws xob tswj hwm hluav taws xob muaj xws li 12V fais fab mov Circuit Court, ntsuas hluav taws xob thiab tswj Circuit Court, thiab tiv thaiv overvoltage circuit. 12V fais fab mov Circuit Court yog tsim los ntawm W4 thiab W5 windings ntawm regulating transformer T, lub rectifier diode VDl-VD4, thiab lim capacitors Cl thiab C2. Qhov ntsuas hluav taws xob ntsuas hluav taws xob yog tsim los ntawm resistor R-R7, Potentiometer RPl, Rm, regulator diode VS, capacitor C3, C4 thiab ua haujlwm amplifier IC (Nl-N3). Lub overvoltage tiv thaiv Circuit Court muaj N3 nyob rau hauv IC, transistor V3, resistor Rl2, thiab relay K. Tsis siv neeg voltage regulator muaj resistors R8-Rll, transistors Vl, V2, DC lub cev muaj zog M, zawv zawg tiv tauj, thiab cov Wl-W3 winding ntawm T. Tom qab txuas qhov kawg ntawm qhov kawg ntawm AC high-power stabilized fais fab mov rau lub mains, ib qho induced voltage yog generated ntawm W4 thiab W5 windings ntawm T. Tom qab VDl-VD4 rectification thiab Cl, C2 filtering, Qhov hluav taws xob no muab kev ua haujlwm tsis ruaj khov ntawm l2V rau IC, Vl, V2, thiab lwm yam ntxiv rau qhov voltage ntawm 12V muaj lwm yam haujlwm. Tom qab voltage faib los ntawm Rl-R3 thiab voltage stabilization los ntawm VS, siv voltage yog muab rau inverted input davhlau ya nyob twg ntawm Nl-N3 feem; Muab cov khoom siv hluav taws xob ua haujlwm rau K thiab V3 ntawm overvoltage tiv thaiv Circuit Shen; Tom qab qhov kev faib hluav taws xob los ntawm R4, RP2, thiab R6, muab qhov ntsuas hluav taws xob rau cov theem zoo nkag ntawm Nl thiab N2; Tom qab qhov kev faib hluav taws xob los ntawm R7, RPl, thiab R5, qhov ntsuas hluav taws xob yog muab rau cov theem zoo nkag ntawm N3.
Kev ceev faj rau kev siv
1. Txhawm rau tiv thaiv kev cuam tshuam cov hlau nplaum sib nqus, qhov kev ncua deb ntawm cov khoom siv hluav taws xob siab thiab cov khoom siv yuav tsum tsis pub tsawg dua 2 meters. Ntau cov ntaub ntawv sib nqus, discs, phaib, thiab lwm yam yuav tsum tau khaws cia kom deb ntawm lub tshuab los ntawm 2 meters los tiv thaiv kev sib nqus magnetization.
2. Cov khoom siv hluav taws xob siab tswj hwm feem ntau suav nrog cov khoom siv nkag (A, B, C), cov khoom siv hluav taws xob tso tawm (a, b, c, n), kev tiv thaiv, thiab cov tub ntxhais hlau plhaub hauv av terminals. Cov terminals no raug txuas nrog rau hauv cov txheej txheem tswj
3. Yog hais tias qhov load imbalance degree siab tshaj 20 [%), ib tug resistive load yuav tsum paralleled nyob rau hauv ib theem ntawm lub teeb load kom sib npaug. Ib yam li ntawd, yog tias cov kab hluav taws xob tsis sib npaug ntawm qhov kev nkag siab kawg siab dua 10 [ feem pua ], qhov hluav taws xob ruaj khov ntawm lub tshuab yuav raug cuam tshuam. Nyob rau lub sijhawm no, ib-theem Siab regulator yuav tsum tau teem rau ntawm qhov kev tawm tswv yim kawg kom sib npaug ntawm cov kab hluav taws xob ntawm qhov kev tawm tswv yim kawg. Qhov sib npaug ntawm cov khoom siv hluav taws xob thiab kev thauj khoom yuav tsum tsis pub tshaj qhov saum toj no, thiab cov khoom siv hluav taws xob tsis sib haum yuav tsum tsawg dua lossis sib npaug li 5 [ feem pua ]
Thaum muaj ib qho luv luv Circuit Court nyob rau hauv lub load ntaus ntawv, tus neeg siv yuav tsum tau kaw lub cuab yeej rau kev soj ntsuam, tshem tawm qhov luv luv Circuit Court txhaum, thiab ces rov pib dua.
Thaum lub sij hawm ua hauj lwm tas mus li ntev, lub tshuab muaj qhov kub thiab txias, thiab nws cov nqi qhia yuav txo qis me ntsis, qis dua tus nqi voltage.
6. Nws yuav tsum tau muab tso rau hauv qhov chaw muaj cua zoo. Yog tias qhov cua tsis zoo, thov nruab ib lub tshuab cua cua hauv tsev
