Kana iyo wiring chamber yekuputika kwemagetsi hitainoda insulating pendi application inoenderana nekuongororwa kwakadzama kweiyo chaiyo kuputika-uchapupu mhando, zvakajairwa zvinodiwa, uye chaiwo mamiriro ekushandisa.
I. Core Zvinodikanwa zveStandard Specifications
1. GB 3836.1-2021 (Zvinodiwa Zvakawanda zveMidziyo mune Inoputika Atmospheres)
Iyi chiyero inosanganisira zvinodikanwa zvenzvimbo dzeguruva asi haiisi mirau inosungirwa pane yekudzivirira varnish kupfapfaidza mumakamuri ewaya eClass II zvishandiso (senge.kuputika-kupisa magetsi emagetsi).
Pamidziyo yeKirasi I (migodhi yemarasha yepasi), mukati memakamuri etambo dzewaya dzinofanirwa kuvezwa nependi isingaite arc (senge 1320 epoxy porcelain pendi) kudzivirira kuputika kwegasi kunokonzerwa nearc. Nekudaro, hapana chakananga chinodiwa chakatemerwa Class II michina (nzvimbo dzisiri dzemigodhi yemarasha dzakadai semiti yemakemikari, zvivakwa zveoiri uye gasi, nezvimwewo).
2. Special Design of Flameproof (Ex d) Equipment
Nzvimbo dzekubatanidza dzenzvimbo inodzivirira moto inofanirwa kurapwa phosphating uye kuvezwa nemafuta ekudzivirira ngura (senge 204-1 anti-rust mafuta) kuve nechokwadi chekuvharwa uye kusadzivirirwa. Kunyangwe mafuta anodzivirira ngura aine zvimwe zvinodzivirira zvivakwa, haisi pendi yakasarudzika inodzivirira.
Kana paine akafumurwa conductor kana flashover njodzi mukati mekamuri yewaya, dhizaini inofanirwa kuenderana nezviyero (semuenzaniso, GB/T 16935.1) kuburikidza neclearance uye creepage chinhambwe, pane kungovimba chete insulating varnish.
3. Insulation Zvinodiwa zveKuwedzera Kuchengetedza (Ex e) Equipment
Midziyo yekuchengetedza yakakwidziridzwa haifanire kuve nemoto mukati mekushanda kwakajairwa, nekamuri yayo yewaya yekuvharisa mashandiro anonyanya kutsamira pazvinhu zvinodzivirira (senge ceramics, epoxy resin) uye conductor sheathing, pane kupfekedza pamusoro pekamuri.
Kana pamusoro pechikamu chekudzivirira chikakuvadzwa, chinofanira kugadziriswa nependi yekudzivirira yegiredhi rimwe chete, asi hapana chinodiwa kuti gomba rose riputirwe.
II. Mafungiro eTekinoroji muKushanda Zvikumbiro
1. Mabasa uye Kugumira kweInsulating Varnish
Zvakanakira: Insulating pendi inogona kukwidziridza kusimba kwepamusoro (senge arc kuramba uye kudzivirira kuvuza), zvichiita kuti inyanyokodzera hunyoro hwepamusoro kana nzvimbo dzine guruva. Semuenzaniso, kushandisa 20-30μm ye epoxy insulating pendi inogona kuwedzera chiyero chekuchengetedza kuchengetedza kusvika pamusoro pe85%.
Ngozi: Insulating pendi inogona kukanganisa kupisa kupisa. Semuyenzaniso, kuputika-chiratidzoheater yemagetsiinokwidziridza kupisa kwekupisa kuburikidza nekutonhodza mhepo uye inert gasi kuzadza. Kupfapfaidza zvakanyanyisa kunogona kukanganisa chiyero chekupisa. Pamusoro pezvo, insulating pendi inofanirwa kupfuudza tembiricha yekumisa bvunzo (semuenzaniso, pamusoro pe150 ° C) kana inogona kukundikana.
2. Indasitiri Kudzidzira uye Manufacturer Maitiro
Ex-dustproof equipment: Vazhinji vanogadzira vanoisa ngura-yekudzivirira primer (semuenzaniso, C06-1 iron red alkyd primer) mukati mekamuri yewaya, asi insulating pendi haisungirwe. Semuyenzaniso, imwe bhokisi rinoputika-risingapindi mota jekiseni rinoshandisa musanganiswa we "primer + arc-resistant magineti pendi", inosimbisa insulation chete munzvimbo inopera.
Kuwedzera midziyo yekuchengetedza: Kunyanya kusimbiswa kunoiswa pakuvimbika kwemechani yekubatanidza conductor (senge anti-loosening terminals) uye kusarudzwa kwezvinhu zvinodzivirira, nepo kupfapfaidza kwegomba kusingakodzeri.
3. Zvimwe Zvinodiwa zveSpecial Scenarios
Mamiriro ekunze ane ngura (semumhenderekedzo yegungwa kana nzvimbo dzemaindasitiri emakemikari): Isa pendi inodzivirira kupisa (semuenzaniso, ZS-1091 ceramic insulating coating) kuti uve nechokwadi chekuti makemikari anodzivirira uye anodzivirira.
High-voltage midziyo (semuenzaniso, pamusoro pe10kV): Pendi yeGradient-thickness anti-corona inofanira kuiswa kudzvanyirira zvinobuda zvishoma.
III. Mhedziso uye Mazano
1. Inosungirwa kupfapfaidza zviitiko
Chete makamuri ewaya emidziyo yeKirasi I (yemigodhi yemarasha yepasi pevhu) ndiwo anodiwa kuti avharwe nependi isingaite arc.
Kana iyo midziyo ikakwidziridza kuita kwayo-inoputika nekuisa pendi inodzivirira (semuenzaniso, kusangana nepamusoro IP ratings kana corrosion resistance), izvi zvinofanirwa kutaurwa zvakajeka mumagwaro etifiketi.
2. Zvisiri-zvinosungirwa asi zvinokurudzirwa zviitiko
Pamidziyo yeKirasi II, zvinokurudzirwa kuisa pendi inodzivirira kana zvinotevera zviripo:
Iyo wiring chamber ine compact space, ine magetsi clearance kana creepage chinhambwe chinosvika pachiyero chiyero.
High ambient humidity (semuenzaniso, RH> 90%) kana kuvapo kweguruva rinoita.
Iyo midziyo inoda kushanda kwenguva refu uye yakaoma kuchengetedza (semuenzaniso, kuvigwa kana kuiswa chisimbiso).
Zvinokurudzirwa kusarudza high-temperature-resistant (≥135 ° C) uye yakasimba adhesive insulating pendi (yakadai se epoxy polyester pendi), nehupamhi hunodzorwa pakati pe20-30μm kuenzanisa kuvhara uye kupisa kupisa.
3. Maitiro uye Verification
Usati wapfapfaidza, iyo mhango inofanirwa kuitirwa sandblasting kurapwa (Sa2.5 giredhi) kuve nechokwadi chekunamatira firimu repende.
Mushure mekupedzwa, kudzivirira kwekudzivirira (≥10MΩ) uye simba re dielectric (semuenzaniso, 1760V/2min) rinofanira kuongororwa, uye bvunzo yekupfapfaidza munyu (semuenzaniso, 5% NaCl mhinduro, maawa 1000 isina ngura) inofanira kupfuudzwa.
Kana iwe uchida kuziva zvakawanda nezvechigadzirwa chedu, ndapotataura nesu!
