02 Kev tsim khoom
2.1 Core
Qhov zoo ntawm Peb -Phase Tsib- Limb Core
High Sib nqus Circuit Court Symmetry:Txhim kho peb -phase tshuav nyiaj li cas.
Luv luv zoo heev -Circuit Performance:Muaj zog tiv thaiv luv luv Circuit Court nrog tsawg sib nqus saturation.
Robust Mechanical Structure:Kev sib xyaw ua ke ntawm cov hlua khi thiab cov cuab yeej clamping ua kom ntev - lub sijhawm ua haujlwm kev ntseeg siab.
Clamping Devices Function: Txhim kho cov tub ntxhais thiab tiv thaiv cov nplooj ntawv silicon steel los ntawm loosening; txhawb nqa qhov hnyav ntawm cov tub ntxhais thiab windings.
Tie Phaj Function: Fasten lub qaum thiab qis clamping li siv bolts, muab lateral siab, thiab tiv thaiv cov tub ntxhais los ntawm loosening.
2.2 Cua txias
Lub kauj yog insulated nrog B-theem, epoxy coated, pob zeb diamond qauv, insulating ntawv, uas yog thermally kho nyob rau hauv lub siab los xyuas kom meej kev sib raug zoo ntawm cov neeg xyuas pib thiab ntawv. Lub coil tau raug ua tiav los xyuas kom meej qhov siab tshaj plaws ntawm cov dej insulating rau hauv lub coil rwb thaiv tsev. Kev sib xyaw ua ke ntawm low-voltage foil winding thiab high-voltage wire winding ua tiav qhov tsis muaj load poob thiab luv luv-circuit impedance, ua tau raws li cov kev xav tau sib txawv. Xyuas kom muaj hluav taws xob sib cais ntawm high-voltage thiab low-voltage windings, txhim khu kev ruaj ntseg. Cov neeg kho tshuab ruaj khov ntawm cov ntawv ci winding thiab rwb thaiv tsev kev ntseeg tau ntawm cov hlau winding txhim kho lub transformer lub neej ua haujlwm. Muaj zog tiv thaiv luv luv thiab kev vibrations ua rau nws haum rau kev ua haujlwm hnyav.
2.3 Tank
Lub tank transformer yog ua los ntawm 304 stainless hlau, Lub tank puag yog tsim los tso cai rau skidding los yog dov nyob rau hauv txhua txoj kev. Lifting cov kev cai muaj plaub lub lifting lugs welded rau lub tank. Lub transformer txais kev kaw lub tank tsim muaj lub zog txaus los tiv thaiv lub siab ntawm 7 psig yam tsis muaj kev cuam tshuam mus tas li, thiab 15 psig yam tsis muaj kev puas tsuaj lossis cuam tshuam rau txee ruaj ntseg.
Lub tank muaj xws li cov cuab yeej siv lub siab ua kom txo tau qhov siab ntawm qhov siab dhau los ntawm kev ua haujlwm ib txwm muaj. Cov yam ntxwv venting thiab sealing yuav tsum yog raws li nram no:
a. Cracking siab: 10psig ± 2psig.
b. Resealing siab: 6psig yam tsawg kawg nkaus.
c. Zero to los ntawm reseal siab rau -8psig.
d. Flow ntawm 15 psig: 35 SCFM yam tsawg kawg nkaus.
