Waterproof Cast-nyob rau hauv- qhov chaw Bus Duct

Waterproof cam khwb cia-hauv- qhov chaw busbar trunking yog lub zog xa hluav taws xob tshwj xeeb tsim los rau qhov chaw hnyav xws li dampness, dej siab, thiab corrosive tej yam kev mob. Los ntawm cov txheej txheem tshwj xeeb casting, tus neeg xyuas pib thiab cov ntaub ntawv rwb thaiv tsev yog solidified rau hauv ib qho qauv, muaj cov dej tsis zoo, rwb thaiv tsev, thiab ib puag ncig adaptability. Nws yog dav siv hauv kev lag luam, kev tsim kho, thiab kev thauj mus los uas yuav tsum muaj kev ruaj ntseg hluav taws xob nruj. Cov hauv qab no muab cov ncauj lus qhia ntxaws ntxaws los ntawm cov yam xws li cov qauv tseem ceeb, cov yam ntxwv tseem ceeb, txoj hauv kev ua haujlwm, thiab cov xwm txheej siv tau:

Cov qauv ntawm cov dej tsis sib haum- nyob rau hauv- qhov chaw busbar trunking yog tsim nyob ib ncig ntawm "waterproof sealing" thiab "kev ruaj ntseg rwb thaiv tsev," thiab feem ntau muaj peb ntu:

1. Tus neeg xyuas pib qhov system: High-purity tooj liab busbars (T2 tooj liab) lossis txhuas busbars feem ntau yog siv los ua qhov nruab nrab, nrog rau qhov chaw kho rau oxidation kuj (xws li tin plating lossis npib tsib xee plating) kom muaj peev xwm nqa tau tam sim no thiab kev ruaj ntseg. Tus neeg xyuas pib npaj yog tsim los raws li tus naj npawb ntawm theem (peb -theem plaub- hlau, peb-theem tsib- hlau, thiab lwm yam), nrog rau qhov sib txawv kom sib npaug ntawm qhov hluav taws xob.
2. Insulation casting txheej: Cov tub ntxhais tsis muaj dej tsis sib haum, ua los ntawm epoxy resin-raws li cov khoom siv sib xyaw (lossis tsis muaj polyester resin, silicone roj hmab, thiab lwm yam) tau sau los ntawm lub tshuab nqus tsev casting txheej txheem los sau qhov khoob ntawm cov conductors, tsim ib qho seamless thiab ntom insulating tag nrho tom qab kho. Cov khoom no muaj cov yam ntxwv ntawm cov dej tsis kam, tshuaj tiv thaiv corrosion, siab kub tsis kam (ntev -lub sijhawm ua haujlwm kub -40℃~ 120 degree), thiab kev rwb thaiv tsev siab (siab dua lossis sib npaug ntawm 1000MΩ).
3. Kev tiv thaiv sab nrauv: Qee cov khoom tau nruab nrog cov hlau (xws li aluminium alloy, galvanized steel sheet) lossis tsis yog -hlau (xws li FRP fiberglass) lub plhaub sab nrauv kom ntxiv dag zog rau cov khoom siv dag zog thiab kev cuam tshuam, thaum tseem pab ua kom sov dissipation. Lub plhaub sab nrauv thiab cov cam khwb cia-hauv- qhov chaw txheej ua haujlwm ua ke los txhim kho qib kev tiv thaiv tag nrho.

1. High-qib dej tsis zoo:

Cov qauv seamless ntawm cov cam khwb cia-hauv- qhov chaw txheej hauv paus thaiv txoj hauv kev ntawm kev nkag mus rau dej, thiab qib kev tiv thaiv tuaj yeem ncav cuagIP66 / IP67(IP66: tiv thaiv siab - dej txau; IP67: tiv thaiv luv luv- lub sij hawm immersion). Qee cov qauv tshwj xeeb tuaj yeem ncav cuag IP68 (ntev- lub sijhawm ua haujlwm hauv qab dej), ua tau raws li qhov xav tau ntawm cov dej nag, tshuaj tsuag, thiab cov xwm txheej ntub dej (xws li cov chaw nres tsheb hauv av thiab cov pas dej da dej).

2. Rwb thaiv tsev thiab kev nyab xeeb kev cia siab:

Cov khoom siv casting muaj qhov tsis tshua muaj hluav taws xob dielectric poob (tsawg dua lossis sib npaug li 0.02%), tsis tshua muaj qhov paug tawm (tsawg dua lossis sib npaug li 5pC), thiab tuaj yeem tiv taus 3kV zog zaus tiv taus qhov ntsuas hluav taws xob yam tsis muaj kev puas tsuaj; nws kuj muaj cov nplaim hluav taws kub hnyiab tau (UL94 V0 qib lossis GB / T 2408-2008 V-0 qib), tsis drip lossis txhawb kev sib tsoo thaum muaj hluav taws kub, thiab ua raws li cov cai tiv thaiv hluav taws.

3. Mechanical thiab ib puag ncig adaptability:

Tag nrho cov qauv muaj zog txhua yam muaj zog (bending zog Ntau dua los yog sib npaug rau 150MPa, compressive zog Ntau dua los yog sib npaug rau 200MPa), thiab tuaj yeem tiv taus kev co thiab cuam tshuam (kev sib ntsib IEC 61373 Qeb 1A railway kev co qauv); nws tiv taus cov kua qaub thiab alkali corrosion (cov tshuaj tsuag ntsev ntau dua los yog sib npaug li 1000 teev), thiab tsim nyog rau corrosive ib puag ncig xws li cov nroj tsuag tshuaj thiab thaj chaw ntug dej hiav txwv.

4. Kev ua haujlwm ruaj khov hluav taws xob:

Nws lub peev xwm nqa tam sim no yog piv rau cov pa tsheb thauj neeg lub cev (piv txwv li, 4000A specification tuaj yeem tiv taus 120% ntawm luv luv- lub sijhawm overload), thiab nws qhov kub thiab txias yog qis (qhov kub nce tsawg dua lossis sib npaug rau 60K raws li ntsuas tam sim no, ua raws li GB / T 7251.23 tus qauv); nws muaj zog luv luv-circuit withstand muaj peev xwm (ncej tiv taus tam sim no Ntau dua lossis sib npaug ntawm 80kA, ncua sijhawm 1 thib ob), ua kom muaj kev nyab xeeb ntawm kev cuam tshuam thaum lub cev tsis ua haujlwm.

Cov ntaub ntawv insulating kua (xws li epoxy resin) yog integrated molded nrog tus neeg xyuas pib hauv pwm siv lub tshuab nqus tsev casting txheej txheem.

• Sealing mechanism: Tom qab cov khoom siv casting kho, nws yog nruj nreem khi rau tus neeg xyuas pib thiab lub plhaub sab nrauv, ua ib qho kev thaiv peb npaug ntawm "tus neeg xyuas pib- txheej rwb thaiv tsev- lub plhaub sab nraud" kom tsis txhob ya raws, plua plav thiab corrosive gases nkag mus.
• Thaum tshav kub kub dissipation mechanism: Cov khoom siv rwb thaiv tsev muaj qhov nruab nrab thermal conductivity (0.2 ~ 0.4 W / m·K), uas, ua ke nrog cov cua kub dissipation ntawm lub plhaub sab nrauv, xyuas kom meej tias cov cua sov ntawm tus neeg xyuas pib yog sib npaug thiab tsis txhob muaj cua sov hauv zos.
• Kev ua kom zoo hluav taws xob zoo: Cov txheej txheem casting ua rau qhov khoob ntawm cov neeg xyuas pib, tshem tawm cov cheeb tsam hauv cheeb tsam uas tshwm sim los ntawm huab cua tsis sib haum thiab txo qhov kev pheej hmoo ntawm corona thiab ib nrab tawm.

Lub ntsiab kom zoo dua ntawm cov dej tsis zoo cam khwb cia- nyob rau hauv - qhov chaw busbar trunking nyob rau hauv nws "ntev- lub sij hawm txhim khu kev qha ua hauj lwm nyob rau hauv hnyav ib puag ncig," nrog rau cov kev siv xws li:

• Qhov chaw ntub dej / dej tsis zoo: chaw nres tsheb hauv av, chaw nres tsheb hauv av, cov chaw kho dej phwj tuaj, chaw ua luam dej (yuav tsum muaj kev tiv thaiv IP67 lossis siab dua);
• Sab nraum zoov qhib-air scenarios : photovoltaic power stations, wind power generation, outdoor charging piles, street light power distribution (resistant to rain and UV aging).
• Corrosive ib puag ncig: kev cob qhia tshuaj, chaw ua haujlwm ntawm ntug dej hiav txwv, kev cob qhia electroplating (resistant rau acid thiab alkali corrosion, ntsev tsuag corrosion);
• Kev huv huv siab / kev lag luam tshwj xeeb: kev ua zaub mov (yuav tsum tau yaug), chaw ua haujlwm tshuaj (tiv thaiv-pwm), cov chaw khaws ntaub ntawv (dej tsis zoo thiab ya raws- pov thawj + tsis tshua muaj).

1. Kev Ceeb Toom:
Nws yog kho nrog ib qho tshwj xeeb bracket nrog qhov sib nrug ntawm Tsawg dua lossis sib npaug li 1.5m kom tsis txhob ntev -lub sij hawm deformation;
Cov ntsiab lus sib txuas yuav tsum siv cov ntsaws ruaj ruaj (xws li silicone roj hmab sealing rings + stainless hlau bolts) kom ntseeg tau tias qib kev tiv thaiv ntawm qhov sib txuas yog ua raws li tag nrho cov qauv.
Xav txog thermal expansion thiab contraction, expansion pob qij txha (cov nyiaj them poob haujlwm ± 50mm) raug ntsia txhua 10m ntawm cov ntu ncaj.

2. Kev tu vaj tse:
Tsis tu ncua (nws raug nquahu kom kuaj xyuas txhua rau lub hlis) rau kev puas tsuaj rau lub plhaub sab nraud thiab seb cov ntsaws ruaj ruaj ntawm lub interface puas yog laus. Tsis tas yuav disassemble lub sab hauv (vim lub txheej txheej yog ib qho qauv).
Hauv qhov chaw ntub dej, kev tiv thaiv rwb thaiv tsev yuav tsum tau saib xyuas (siv lub 2500V megohmmeter, theem- mus rau -theem thiab theem- rau- av rwb thaiv tsev tiv thaiv ntau dua lossis sib npaug ntawm 1000MΩ).
Avoid prolonged exposure to high temperatures (>120 degree) los yog muaj zog ultraviolet hluav taws xob; yog tias tsim nyog, nce kev ntsuas shading / tshav kub rwb thaiv tsev.

Waterproof cam khwb cia-nyob rau hauv- qhov chaw busbar trunking, los ntawm nws cov kev tsim qauv ntawm cov ntaub ntawv, txheej txheem, thiab cov qauv, kov yeej cov kev txwv ntawm daim ntawv thov ntawm tsoos busbar trunking nyob rau hauv hnyav ib puag ncig. Nrog nws cov txiaj ntsig tseem ceeb ntawm kev ua dej tsis zoo, kev ua neej ntev, thiab kev saib xyuas tsis zoo, nws tau dhau los ua cov kev daws teeb meem zoo tshaj plaws rau kev xa hluav taws xob hauv cov av ntub dej, dej- nplua nuj, thiab corrosive ib puag ncig. Nws cov qauv kev ua tau raws li GB/T 7251.23 "Low-voltage switchgear thiab controlgear assemblies - Part 23: Busbar trunking with particular requirements," thiab nws tau dhau CCC thiab CE daim ntawv pov thawj, ua tau raws li cov kev xav tau ntawm domestic thiab thoob ntiaj teb engineering tej yaam num.
