1. Chalk zotenthetsera zowonjezera
Chingwe chachitsulo chotenthetsera, chomwe chimadziwika kuti kutentha kwazitsulo, ndizomwe zimakonda kwambiri poyendetsa magetsi. Iwo amagwiritsidwa ntchito pa malo a zingwe mkulu ndi otsika voteji mtanda yolumikizidwa kapena zingwe kumiza mafuta. Poyerekeza ndi zida zachikhalidwe zazingwe, ndizochepera, zolemera mopepuka, ndipo ndizotetezeka, zodalirika komanso zosavuta kukhazikitsa. Amagwiritsidwa ntchito kwambiri m'malumikizidwe apakatikati ndi ma terminals azingwe zolumikizidwa ndi zingwe kapena zingwe zomizidwa ndi mafuta zamagetsi zama 35KV ndi pansipa. Chogulitsachi chimagwirizana ndi muyezo wa GB11033, kutentha kwa nthawi yayitali ndi -55 ℃ ～ 125 ℃, moyo wokalamba ndi wautali zaka 20, kuchuluka kwa shrinkage kozungulira ndi ≥50%, kotenga kutalika kwa kutalika ndi <5% , ndipo kutentha kwa shrinkage ndi 110 ℃ ～ 140 ℃.
2. Chingwe chokulunga chachingwe
Zolumikizira zingwe zokutira nthawi zambiri zimagwiritsidwa ntchito pazolumikizira zamagetsi zotsika kwambiri. Zolumikizira zingwe zokutidwa zimavulazidwa ndi tepi yoteteza pulasitiki. Kukhazikika kwake, kusakhazikika kwake, komanso kukongoletsa kwake sizofanana ndi mitu yolumikizira kutentha. Kukula kwake kumagwiritsidwa ntchito kumangokhala ndi zingwe zokhala ndi m'mimba mwake zosakwana kapena zofanana ndi 70mm2. Itha kuyikidwa poyera, osayikidwa pansi, ndipo imakhala ndi chitetezo chabwinobwino. Kukhudza zinthu zakuthwa kapena kugunda ndi mphamvu yakunja kumatha kuwononga tepi yotetezera chilonda ndikupangitsa ngozi kutayikira. Koma pali mwayi, ndiye kuti, mtengo wake ndi wotsika ndipo zomangamanga ndizosavuta.
3, zolumikizira zazingwe zazingwe zosazizira
Ma cholumikizira azingwe osazizira tsopano amagwiritsidwa ntchito kwambiri ndi machubu owongoletsa kuzizira, okhala ndi ma voliyumu kuyambira 10kV mpaka 35kV. Kwa mitu yolumikizira yozizira yozizira, 1kV kalasi imagwiritsa ntchito machubu osazizira ozizira kuti atetezedwe, ndipo gulu la 10kV limagwiritsa ntchito malo olumikizirana ozizira okhala ndi zigawo zamkati ndi zakunja zotetezera. Chingwe chowongolera chozizira chimagwiritsa ntchito kutambasuka kwabwino kwa kukana kwamisozi yayikulu komanso kukhathamira kwakukulu kwa mphira wa silicone, ndipo imagwiritsa ntchito zida zothandizirana zapulasitiki zopitilira kuti zikulitse zowonjezera zoyambira kumtunda wakunja wofunikanso. Pambuyo pokonza, zida zothandizira ndizolumikizidwa mosalekeza. Chotsani, ndipo zowonjezera zimakulungidwa mwamphamvu pachingwe ndi kukomoka kwa mphira. Zoyenera kugwiritsidwa ntchito: -50 ～ 200.
Mitu yachitsulo yosazizira yozizira ili ndi maubwino ocheperako, kugwira ntchito mwachangu komanso mwachangu, palibe zida zapadera, ntchito zingapo zosiyanasiyana ndizofotokozera zamagulu ochepa. Poyerekeza ndi zida zazingwe zotentha, sizifunikira kutenthedwa ndi moto, ndipo mukayika, sizingasunthike kapena kuwerama ngati zida zazingwe zotenthetsera kutentha. Palibe chowopsa chilichonse chodula pakati pazazipangizo (chifukwa zida zazingwe zosazizira zimapangidwa ndi kukana kwa misozi, mphira wokwera wa silicone mphira wabwino kwambiri).
4, mitundu yolumikizira chingwe yolumikizira
Kunena mwachidule, zolumikizira zamtundu wa cast ndizogwiritsa ntchito nkhungu kukonza mutu wa chingwe, ndikutsanulira utomoni wa epoxy, ndikuchotsa nkhunguyo mutayanika. Ndizovuta kwambiri ndipo sizitha kutsanulidwa pamafunde kuti muchepetse chinyezi ndikuchepetsa kutchinjiriza kwa mutu wa chingwe.
5, zopangira chingwe
Ndizowonjezera zomwe zimapangidwa ndi jekeseni wa mphira wa silicon m'magawo osiyanasiyana, kuwotcha ndi kuumba nthawi imodzi, kumangotsala mawonekedwe olumikizirana, ndikuyika zingwe panthawi yomanga pamalo. Ntchito yomanga imachepetsa zinthu zosayembekezereka m'deralo kutsika pang'ono. Chifukwa chake, chowonjezeracho chimagwiritsa ntchito phindu lalikulu ndipo ndi chiwongolero cha chitukuko cha zida zolumikizidwa ndi zingwe. Komabe, ukadaulo wopanga ndi wovuta ndipo umaphatikizapo magawo angapo ndi mafakitale.
