02 Kev tsim khoom

2.1 Pressure Relief Gauge

Lub ntsuas qhov ntsuas siab ntawm lub ncoo -mounted transformer yog cov cuab yeej saib xyuas thiab kev tiv thaiv. Nws tsis tu ncua qhia lub siab sab hauv los ntawm cov xim - coded dial thiab cia li vents txaus ntshai overpressure- ua los ntawm faults xws li internal arcing- los tiv thaiv tank rupture. Ib qho kev taw qhia pom tau tshwm sim tom qab ua haujlwm kom pom tias muaj kev tso tawm siab, pab txhawm rau txheeb xyuas qhov yuam kev thiab kev saib xyuas.

2.2 Cua txias

Lub 200A, 25 kV rotatable feedthru insert yog engineered los xa ob bushings los ntawm ib qho khoom siv bushing zoo, streamlining ob txoj haujlwm tseem ceeb: hloov radial - pub transformers rau hauv pub -thru configurations thiab integrating nyob rau hauv - kab ntes tiv thaiv nrog practicality thiab practicality. Nws qhov tshwj xeeb tshaj plaws yog patented integrated torque- txwv ratchet, uas tiv thaiv bushing zoo studs los ntawm kev puas tsuaj thaum lub sij hawm installation. Qhov no ratchet mechanism kuj ua rau 360℃kev sib hloov ntawm cov ntxig, tso cai rau cov neeg ua haujlwm los tso nws qhov zoo rau cov ntawv thov tshwj xeeb. Lub rooj sib txoos uas muaj nyob rau hauv cov khoom siv ruaj ntseg feedthru hauv nws txoj haujlwm xav tau ib zaug hloov kho. Tsim los nrog tag nrho -txoj kev tam sim no tooj liab thiab peroxide- kho EPDM roj hmab, qhov ntxig tau ua raws li IEEE Std 386™-2006. Thaum ua ke nrog cov khoom ntawm qhov sib npaug sib npaug, nws muab kev tiv thaiv kev sib txuas tag nrho.

2.3 Tank

Pad mounted transformer roj tank tsim muaj cov qauv tshwj xeeb thiab kev ua haujlwm. Lub tank ntawm hom transformer no feem ntau yog ua los ntawm cov khoom siv hlau muaj zog, uas tuaj yeem tiv taus kev cuam tshuam ntawm ib puag ncig sab nraud, thiab muaj huab cua zoo thiab corrosion kuj. Lub tank tsis tsuas yog khaws cov roj insulating, tab sis kuj muab cov cua txias tsim nyog thiab kev tiv thaiv ntawm cov khoom siv hluav taws xob sab hauv.

Cov roj tank ntawm ncoo mounted transformer feem ntau yog tsim los kaw kom tsis txhob nkag mus rau sab nraud ntawm cov dej noo thiab cov kab mob, uas tuaj yeem tswj tau qhov kev ua tau zoo ntawm cov roj insulating thiab txuas nws lub neej kev pab cuam. Insulating roj plays lub luag haujlwm tseem ceeb hauv kev tsim qauv no, ntxiv rau kev muab kev tiv thaiv kev tiv thaiv, nws kuj tseem pab kom cov cua sov los ntawm convection thiab cua sov dissipation mechanisms, yog li ua kom muaj kev nyab xeeb ntawm kev hloov pauv hauv cov khoom siv siab.

Txhawm rau ua kom yooj yim rau kev khiav lag luam thiab kev saib xyuas, ntau lub hauv av transformers tau nruab nrog saib Windows, roj qib ntsuas thiab ntsuas kub ntawm lub tank los saib xyuas cov kev hloov pauv ntawm cov roj qib thiab qhov kub ntawm lub sijhawm. Tsis tas li ntawd, cov duab ntawm lub tank feem ntau yog tsim los kom compact, yog li nws tuaj yeem hloov tau yooj yim nyob rau hauv ib puag ncig hauv nroog, thiab hauv qab feem ntau nruab nrog cov qauv leakproof los xyuas kom meej tias thaum muaj kev sib tsoo, nws tuaj yeem tiv thaiv kev ua qias tuaj rau ib puag ncig.

2.4 Lub Rooj Sib Tham Kawg

Base Installation: Txhim kho lub hauv paus transformer nyob rau hauv txoj hauj lwm xaiv, kom ntseeg tau tias nws yog qib thiab ruaj khov.

Core thiab Winding Installation: Ntxig lub transformer core thiab windings rau hauv lub thawv, kom ntseeg tau tias kev sib raug zoo thiab ruaj ntseg txuas.

Kev kho rwb thaiv tsev: Insulate lub windings siv roj-impregnated lossis lwm yam ntaub ntawv insulating los txhim kho kev nyab xeeb thiab kev ua haujlwm.

Kev sib txuas ntawm Terminal: Txhim kho qhov kev sib txuas ntawm qhov hluav taws xob siab thiab qhov hluav taws xob tsawg, kom ntseeg tau tias lawv muaj kev nyab xeeb.

Sealing thiab Roj Sau: Kaw lub qhov thaiv kom tsis txhob muaj dej thiab plua plav nkag, thiab sau nrog cov roj hloov pauv yog tias tsim nyog.

 

2.5 kub gauge

Qhov ntsuas kub ntawm lub ncoo-mounted transformer yog ib qho khoom siv rau kev saib xyuas cov roj sab hauv lossis cua kub cua. Cov chav nyob ib txwm muaj feem ntau qhia ncaj qha - nyeem ntawvdial -type (bimetallic) ntsuas, thaum niaj hnub transformers feem ntau yog nruab nrogelectronic gaugesuas muab cov teeb liab tso tawm tej thaj chaw deb (xws li, 4-20mA lossis digital kev sib txuas lus) rau SCADA systems thiab tshaj-kub tswb. Nws lub luag haujlwm tseem ceeb yog ua kom muaj kev nyab xeeb ntawm kev ua haujlwm los ntawm kev tiv thaiv overheating vim muaj kev tiv thaiv overloads lossis txias tsis ua haujlwm, yog li tiv thaiv lub neej ntawm rwb thaiv tsev thiab optimizing load tswj.

2.6 low-voltage nruab nrab bushing

Qhov qis-voltage nruab nrab bushing muab cov ntsiab lus txuas sab nraud rau lub transformer sab hauv nruab nrab. Nws feem ntau nta ib qho tag nrho insulated, tuag- pem hauv ntej tsim nrog aloadbreak interfacerau kev nyab xeeb kub-kab ua haujlwm thiab suav nrogintegrated grounding/test point. Qhov no tso cai rau kev yooj yim hauv av, kev sib cais muaj kev nyab xeeb, thiab yooj yim disconnect rau kev ntsuas rwb thaiv tsev, ua rau nws tseem ceeb rau ob qho tib si kev nyab xeeb thiab kev saib xyuas thaj chaw.
