High frekans switch mòd pouvwa ekipman pou karakteristik pwodwi
High-frekans switching pouvwa ekipman (yo rele tou switching redresman SMR) opere nan frekans segondè atravè MOSFET oswa IGBT. An jeneral, frekans chanjman an kontwole nan seri 50-100kHz pou reyalize efikasite segondè ak miniaturizasyon. Nan dènye ane yo, kapasite pouvwa a nan chanje redresman te kontinye elaji, ak kapasite inite sèl la te elaji soti nan 48V / 12.5A, 48V / 20A a 48V / 200A, 48V / 400A. High-frekans switching pouvwa ekipman se yon altènatif modènize redresman tradisyonèl yo (redresman silikon, redresman tiristor). High-frekans switching pouvwa ekipman byen vit okipe mache a akòz avantaj absoli yo tankou fasilite nan itilize, ti gwosè, efikasite segondè, operasyon ki estab, ak kouch metikuleu. Li se lajman ki itilize nan galvanoplastie, elektwoliz, oksidasyon ak lòt endistri tretman sifas, e li te resevwa lwanj inanim nan men nouvo ak ansyen kliyan.
Pwodwi sa a trete ak presizyon lè l sèvi avèk enpòte konpozan mak pi popilè yo ak entènasyonalman avanse plen-pon varyateur konvèti teknoloji, fè pèfòmans nan tout machin nan ki estab ak bon jan kalite a plis serye. 2. Machin an antye gen fonksyon alam pwoteksyon otomatik ak fonksyon demaraj mou pou survoltaj, surkouran, surtanperati, kous kout ak mank de egalizasyon. Epi yo ka ekipe ak kontwòl tan ak koòdone òdinatè. 3. Fòm vag pwodiksyon DC a se yon vag kare wo-frekans ak yon koyefisyan rid<1 [%], which can increase the number of plating, resist passivation, enhance the gloss of the coating surface and the core degree of the dark corners of the plated parts. It can also reduce the loss of raw materials and meet various special requirements of the electroplating industry. The 4SFG series adopts air-cooling design and is easy to install. And equipped with a remote control device, easy to operate. The machine can be switched on and off with load, reducing the cumbersome adjustment procedures. 5. Small in size and light in weight, the whole machine is manufactured using a full range of anti-corrosion processes, which enhances the anti-corrosion capability of the product and extends its service life. 6. Highly efficient and energy-saving, the working efficiency reaches more than 90[%], and any voltage-to-current ratio is always linearly matched. It eliminates the losses of the voltage regulator and main transformer of the traditional rectifier, saves more than 35% of energy, and greatly reduces the cost of electroplating. It is actually the most sensible choice in the surface treatment industry.
Dapre prensip kontwòl TRC, gen twa metòd:
1. Pulse Width Modulation (pulseWidthModulation, abreje kòm) gen yon peryòd switch konstan ak chanje sik devwa a pa chanje lajè batman kè a. 2. Batman Frekans Modulation (abreje kòm pFM) gen yon lajè batman kondiksyon konstan ak chanje sik devwa a pa chanje frekans nan fonksyone. 3. Modulation ibrid, tou de lajè batman kondiksyon an ak frekans fonksyone chanje yo pa fiks epi yo ka chanje youn ak lòt. Li se yon melanj de de metòd ki anwo yo. High-frekans switching ekipman pou pouvwa teyorikman ka diminye pèt chanje a zewo san yo pa ogmante siyifikativman vitès la chanje, ak bri a tou piti.
