Kev hloov pauv sai thiab tseem ceeb hauv AC voltage hauv lub network ua rau kev ua haujlwm tsis ruaj khov ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob hauv tsev. Nyob rau hauv qhov xwm txheej hnyav, xws li surges tuaj yeem ua rau cov khoom siv hluav taws xob tawg thiab ua tsis tiav. Hauv qhov no, kev siv cov khoom siv hluav taws xob hluav taws xob hluav taws xob yog qhov tseem ceeb. Ntau ntxiv, cov neeg siv tau xaiv rau inverter voltage stabilizers rau lub tsev.
Txheej txheem cej luam ntawm Voltage Stabilizers
AC kab hluav taws xob stabilizers muaj keeb kwm hloov pauv siv ntau yam qauv tsim hluav taws xob. Tam sim no, muaj ntau hom stabilizers:
- relay voltage stabilizers;
- electromechanical servo stabilizers;
- hluav taws xob thyristor lossis triacstabilizers;
- inverter voltage regulators.
Cov zis hluav taws xob ntawm relay stabilizers hloov pauv hauv cov kauj ruam los ntawm kev hloov cov windings ntawm lub mains transformer los ntawm kev sib cuag ntawm cov hluav taws xob muaj zog relays. Qhov tseeb stabilization yog txiav txim los ntawm tus naj npawb ntawm switched windings. Muaj peev xwm muaj los ntawm 5 mus rau 10 xws li windings.
Hauv electromechanical stabilizers, DC servo tsav txav cov graphite txhuam ntawm cov khoom tam sim no raws li cov lem ntawm autotransformer winding. Tus nqi ntawm cov teeb liab tswj yog nyob ntawm qhov sib txawv ntawm qhov hluav taws xob input thiab qhov siv hluav taws xob sib txuas rau 220 V. Thaum qhov sib txawv raug tshem tawm, lub servo lub cev muaj zog tswj cov cuab yeej nkag mus rau hom kev taug qab.
Hauv hluav taws xob stabilizers, kev hloov pauv ntawm lub tshuab hluav taws xob siv los ntawm cov actuators yog tswj los ntawm tus maub los.
Lub tshuab hloov pauv yog tsim los ntawm semiconductor triacs lossis thyristors. Kev ua haujlwm ntawm tus maub los yog txiav txim siab los ntawm software ntsia ntawm lub Hoobkas ntawm cov khoom.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm inverter stabilizer
Kev ua haujlwm ntawm inverter voltage stabilizer yog raws li lub hauv paus ntsiab lus ntawm kev hloov dua siab tshiab. Ua ntej, cov tswv yim AC voltage hloov mus rau DC, thiab tom qab ntawd qhov kev hloov pauv hloov pauv tau ua tiav. Xyuas kom cov zis ntawm lub cuab yeej ruaj khov alternating voltage 220 V yog nqa tawm los ntawm electronics ntawm inverter voltage stabilizers.
Nws tsis muaj lub zog loj hloov pauv. Qhov sib xyaw ntawm cov stabilizers suav nrog cov khoom siv hluav taws xob hauv qab no:
- input network LC lim;
- semiconductor diode puv-yoj rectifier;
- lub zog kho qhov cuab yeej;
- block ntawm cia capacitor;
- inverter converter;
- quartz moos oscillator ntawm ruaj khov zaus;
- high pass output filter;
- microprocessor maub los.
Passive input mains lim yog siv los tshem tawm cov kev cuam tshuam ntau zaus thiab ua kom lub zog luv luv hauv lub zog loj. Lub rectifier hloov cov hluav taws xob hloov mus rau hauv ib qho ncaj qha, ib feem ntawm cov hluav taws xob hluav taws xob uas tau khaws cia rau hauv ib qho thaiv ntawm cov hluav taws xob muaj peev xwm electrolytic capacitors. Lawv yog qhov chaw thaub qab uas tuaj rau hauv kev ua haujlwm thaum muaj qhov tsis zoo ntawm lub zog hluav taws xob lossis nws lub sijhawm luv luv.
Txoj hauj lwm ntawm tus corrector yog kom normalize lub hwj chim los ntawm lub network, tiv thaiv overload ntawm lub stabilizer thaum nws ua hauj lwm. Lub inverter-converter restores AC voltage los ntawm DC. Vim yog kev koom tes ntawm quartz oscillator hauv nws txoj haujlwm, qhov tso zis hluav taws xob muaj daim ntawv ntawm cov ntshiab sinusoid nrog zaus ntawm 50 Hz nrog qhov yuam kev tsis tshaj 0.5%.
Tus maub los tswj kev ua haujlwm ntawm cov zis hluav taws xob stabilization circuits thiab ntsuas lub xeev ntawm cov blockspab kiag li lawm nrog rau kev tso tawm cov txiaj ntsig rau cov khoom siv. Nws teeb meem cov lus txib kom cia li kaw lub lag luam ntawm lub stabilizer nyob rau hauv cov kev tshwm sim hais tias cov input voltage tus nqi mus dhau qhov kev cai ntau yam txiav txim los ntawm cov yam ntxwv kev.
Specifications of stabilizers
Thaum xaiv lub tsev network AC voltage stabilizer, yuav tsum tau them nyiaj mloog zoo rau nws cov yam ntxwv tseem ceeb, uas suav nrog cov hauv qab no:
