Chiyambi cha mitundu yosiyanasiyana ya zowonjezera za chingwe

1. Zowonjezera za chingwe chotenthetsera
Zipangizo za chingwe zotenthetsera kutentha, zomwe zimadziwika kuti mitu ya chingwe chotenthetsera kutentha, ndizomwe zimagwiritsidwa ntchito kwambiri poyendetsa magetsi. Nthawi zambiri zimagwiritsidwa ntchito pa ma terminal a zingwe zolumikizidwa ndi magetsi okwera komanso otsika kapena zingwe zomizidwa ndi mafuta. Poyerekeza ndi zowonjezera za zingwe zachikhalidwe, ndi zazing'ono kukula, zopepuka kulemera, ndipo ndizotetezeka, zodalirika komanso zosavuta kuyika. Zimagwiritsidwa ntchito kwambiri pamalumikizidwe apakati ndi ma terminal a zingwe zolumikizidwa ndi magetsi kapena zingwe zomizidwa ndi mafuta zokhala ndi magetsi a 35KV ndi pansi. Chogulitsachi chikugwirizana ndi muyezo wa GB11033, kutentha komwe kumagwiritsidwa ntchito kwa nthawi yayitali ndi -55℃ ～125℃, moyo wokalamba ndi wautali ngati zaka 20, liwiro la kuchepera kwa radial ndi ≥50%, liwiro la kuchepera kwa longitudinal ndi <5%, ndipo kutentha kwa kuchepera ndi 110℃ ～140℃.

2. Zowonjezera za chingwe chokulungidwa
Zolumikizira za chingwe zokulungidwa nthawi zambiri zimagwiritsidwa ntchito mu zolumikizira za chingwe zotsika mphamvu. Zolumikizira za chingwe zokulungidwa zimakulungidwa ndi tepi yapulasitiki yoteteza kutentha. Kusalowa madzi, kulimba, komanso kukongola kwake sikwabwino ngati mitu ya chingwe yotenthetsera kutentha. Kuchuluka kwa ntchito kumangogwiritsidwa ntchito pa zingwe zokhala ndi mainchesi awiri kapena anayi m'mimba mwake wochepera kapena wofanana ndi 70mm2. Zingayikidwa poyera, osati pansi, ndipo sizigwira ntchito bwino. Kukhudza ndi zinthu zakuthwa kapena kugunda ndi mphamvu yakunja kungawononge tepi yoteteza mabala ndikuyambitsa ngozi zotayikira. Koma pali ubwino, ndiko kuti, mtengo wake ndi wotsika ndipo kapangidwe kake ndi kosavuta.

3, zolumikizira za chingwe zozizira zomwe zimatha kuphwanyika
Zolumikizira za chingwe zozizira tsopano zimagwiritsidwa ntchito kwambiri ndi machubu owongolera kupsinjika kozizira, okhala ndi mphamvu yamagetsi kuyambira 10kV mpaka 35kV. Pa mitu ya chingwe chozizira chozizira, kalasi ya 1kV imagwiritsa ntchito machubu oteteza kuzizira oziziritsa kuti ateteze mphamvu, ndipo kalasi ya 10kV imagwiritsa ntchito zolumikizira zozizira zoziziritsa ndi zigawo zotchingira mkati ndi kunja. Zipangizo zowonjezera za chingwe chozizira zimagwiritsa ntchito kulimba kwabwino kwa kukana misozi kwambiri komanso mphira wa silicone wolimba kwambiri, ndipo imagwiritsa ntchito zipangizo zothandizira za pulasitiki zozungulira kuti zikulitse zowonjezera zoyambirira ku miyeso yakunja yomwe ikufunika panthawiyi. Pambuyo poyika, zipangizo zothandizira zimalumikizidwa nthawi zonse. Tulutsani, ndipo zowonjezerazo zimakulungidwa mwamphamvu pa chingwe ndi kulimba kwa rabara. Malamulo ogwiritsira ntchito: -50～200.

Mitu ya chingwe chozizira imafupika bwino ili ndi ubwino wa kukula kwake kochepa, kosavuta komanso kofulumira, palibe zida zapadera, mitundu yosiyanasiyana ya ntchito komanso zinthu zochepa zomwe zimagwiritsidwa ntchito. Poyerekeza ndi zowonjezera za chingwe chozizira, sichifunika kutenthedwa ndi moto, ndipo chikayikidwa, sichidzasunthidwa kapena kupindika ngati zowonjezera za chingwe chozizira. Palibe chiopsezo cholekanitsidwa pakati pa zigawo zamkati za zowonjezera (chifukwa zowonjezera za chingwe chozizira zimapangidwa ndi kukana kwambiri misozi, mphira wa silicone wosasunthika kwambiri. Mphamvu yabwino kwambiri yolimbitsa).

4, zolumikizira za chingwe chamtundu wa cast
Mwachidule, zolumikizira za chingwe zopangidwa ndi cast-type ndi kugwiritsa ntchito nkhungu kuti zikonze mutu wa chingwe, kenako kutsanulira epoxy resin mmenemo, kenako kuchotsa nkhunguyo ikauma. Ndi yovuta kwambiri ndipo singathe kutsanulidwa mu madzi kuti ipewe chinyezi ndikuchepetsa kutentha kwa mutu wa chingwe.

5, zowonjezera za chingwe zokonzedweratu
Ndi chowonjezera chomwe chimapangidwa poika mphira wa silikoni m'zigawo zosiyanasiyana, kuzipanga ndi kuziumba nthawi imodzi, kusiya mawonekedwe olumikizirana okha, ndikuyika zingwe panthawi yomanga pamalopo. Njira yomangira imachepetsa zinthu zosayembekezereka zomwe sizingachitike m'chilengedwe kukhala zochepa. Chifukwa chake, chowonjezeracho chili ndi phindu lalikulu logwiritsidwa ntchito ndipo ndiye njira yopangira zida za chingwe cholumikizidwa. Komabe, ukadaulo wopanga ndi wovuta ndipo umakhudza magawo ndi mafakitale osiyanasiyana.
