2.3 Uchaguzi wa teknolojia ya vifaa kamili

Seti kamili ya vifaa ni pamoja na mfumo wa udhibiti wa usambazaji wa nguvu wa masafa ya kati, mfumo wa kipimo cha joto cha nyuzi ya macho ya mbali-infrared, mfumo wa udhibiti wa kitanzi cha joto, benki ya capacitor ya fidia ya nguvu tendaji, mwili wa tanuru ya kupokanzwa, n.k.

Mfumo wa udhibiti wa nguvu wa masafa ya kati:

2.3.1 Ugavi wa umeme wa mzunguko wa kati ni kifaa cha frequency variable ya thyristor, voltage ya pembejeo ni 380V , 50Hz , na nguvu ya pato ni 200KW . Nguvu inaweza kubadilishwa kwa mikono au moja kwa moja kulingana na hali ya joto iliyowekwa. Mzunguko wa pato ni 8KHz (ufuatiliaji wa masafa otomatiki). Rangi ya baraza la mawaziri imedhamiriwa kulingana na mahitaji ya mtumiaji, saizi ya muhtasari ni 2000 × 1500 × 1300mm, na urefu wa katikati ni 1000mm.

2.3.2 Cartridge aina ya rack pamoja ya silicon

Kirekebishaji na sehemu ya kigeuzi cha thyristor huchukua fremu ya hivi punde ya silicon iliyojumuishwa na utumizi wa hataza. Njia hii ya ufungaji hufanya disassembly na mkusanyiko wa thyristor iwe rahisi zaidi na kisayansi. Wakati wa kuchukua nafasi ya thyristor, tu kuifungua Bolt ya kuimarisha inaweza kuchukua nafasi ya kipengele chochote cha thyristor katika mkusanyiko. Zaidi ya hayo, njia hii ya ufungaji inapunguza kikamilifu kiasi cha sehemu ya SCR, ambayo sio tu huongeza nafasi ya uendeshaji katika baraza la mawaziri la umeme, lakini pia hupunguza sana kupoteza kwa mstari.

2.3.3 Kiyeyeyusha cha kusawazisha cha DC chenye uwezo mkubwa

Reactor ya laini ni muhimu sana kwa usambazaji wa nguvu thabiti, ina kazi mbili. Kwanza, fanya sasa pato la rectifier laini na imara. Pili, wakati thyristor inverter ni ya muda mfupi, kiwango cha ukuaji wa sasa wa mzunguko mfupi na ukubwa wa kiwango cha juu cha mzunguko mfupi ni mdogo. Ikiwa muundo wa parameta wa reactor ya chujio hauna maana, nyenzo za msingi si nzuri au mchakato wa utengenezaji hautoshi, itakuwa na athari kubwa juu ya uaminifu wa kazi wa usambazaji wa umeme wa mzunguko wa kati.

2.3.4 SCR yenye uwezo mkubwa

Ili kuhakikisha kuegemea kwa utendakazi wa kifaa, virekebishaji na vibadilishaji vya thyristors hutumia KP yenye uwezo mkubwa wa kituo cha Xiangfan na silikoni ya KK ili kuhakikisha utendakazi thabiti wa kifaa.

2.3.5 Tumia njia za fidia za mfululizo na sambamba ili kupunguza upotevu wa njia za upokezaji

Ili kupunguza upotevu kwenye mstari wa maambukizi ya mzunguko wa kati, capacitor ya fidia ya inverter imeunganishwa katika mfululizo na fomu ya sambamba ya mara mbili ya voltage.

2.3.6 Vigezo kuu vya mzunguko na msingi wa uteuzi wa sehemu

Vigezo vilivyokadiriwa vya saketi kuu ya usambazaji wa umeme wa masafa ya kati huonyeshwa kwenye jedwali lifuatalo:

The inductor is composed of a furnace shell, an induction coil, a stainless steel water collector and a furnace lining. The induction coil is combined with the parameters of the annealed copper alloy tube to optimize the design with special computer software and make it in combination with actual experience. It can ensure the best electromagnetic coupling efficiency under the same capacity. Induction coils with 99.99% of T2 rectangular copper wire made, the induction coil outer insulating electrostatic spray process the epoxy resin insulating layer of high strength, pressure-resistant insulating layer is greater than 5000V .

The inner layer of the induction coil is made of white corundum lining, and the outside of the lining and between the coils are fixed with refractory cement (American Union Mine), which can play a role in insulation and heat preservation. At the same time, the strength of the white corundum lining is further increased, effectively avoiding copper wire damage to the lining.

Maji yote ndani na nje ya sensor hukusanywa kwenye mitego miwili ya maji ya chuma cha pua, ambayo imeunganishwa na njia kuu ya maji ya maji na mabomba. Mtozaji wa maji ya chuma cha pua ni nzuri na ya vitendo, ambayo inaweza kuepuka kwa ufanisi ushawishi wa uharibifu wa joto wa coil ya induction kutokana na kutu ya bomba la maji na kuziba kwa njia ya maji.
