Epoxy pipe vagadziri vanosuma iyo tsanangudzo ye insulating materials

Zvinoenderana neyakajairwa chiyero chenyika GB2900.5, tsananguro yemidziyo yekudzivirira ndeye: “midziyo inoshandiswa kugadzira magetsi insulate zvishandiso”. Kureva, chinhu chinodzivirira chinovhara nzira yemagetsi. Resistivity yayo yakakwira zvakanyanya, kazhinji muhuwandu hwe10-10Ω·m. Senge mumotokari, zvinhu zvinodzivirira zvakatenderedza maconductor zvinotsaura kutendeuka uye kubva kune yakadzika stator core kuti ive nechokwadi chekushanda kwakachengeteka kwemota.

Zvishandiso zvinoumbwa nezvinhu zvine resistivity ye109 kusvika 1022 Ω• Cm zvinodaidzwa kuti insulating materials mumagetsi tekinoroji, anozivikanwawo semadielectrics. Zvichitaurwa zviri nyore, chinhu chinoparadzanisa muviri unochajiwa kubva kune mamwe mativi. Iyo insulating zvinhu ine yakakura kwazvo kuramba kune DC ikozvino. Pasi pekuita kweDC voltage, inenge isiri-conductive kunze kweiyo diki diki yekudonha kwepasi ikozvino. Kune AC ikozvino, kune capacitive ikozvino inopfuura, asi zvakare inoonekwa seisina-conductive. Conductive. Iyo yakakwirira iyo resistivity ye insulating material, zviri nani kuita insulating.

Mu tekinoroji yemagetsi, insulating zvinhu zvinowanzoreva zvinhu zvine resistivity yakakura kupfuura gumi kusvika ku10th simba Ω.cm. Basa remidziyo yekuisa insulating inonyanya kutsaura zvikamu zvipenyu zvezvinogona zvakasiyana mumidziyo yemagetsi.

Naizvozvo, insulating zvinhu zvinofanirwa kuve neakanaka dielectric zvivakwa, ndiko kuti, ivo vanofanirwa kuve neakakwira insulation kuramba uye kumanikidza simba, uye kukwanisa kudzivirira tsaona senge kuvuza, creepage uye kuparara; chechipiri, kupisa kwekudzivirira kwezvinhu zvinodzivirira zviri nani, kunyanya kune Inovimbiswa kuti hapazovi nekuchinja kwekuita nekuda kwekupisa kwenguva refu; uyezve, ine yakanaka yekupisa conductivity, hunyoro kuramba, yakakwirira mechanical simba, uye nyore kugadzirisa.

Insulation zvinhu zvinowanzo shandiswa nevemagetsi zvinogona kukamurwa kuita inorganic zvinhu uye organic zvinhu zvinoenderana neakasiyana makemikari zvivakwa. Kune marudzi matatu emidziyo yekuisa insulating uye yakasanganiswa insulating zvinhu.
