Zomwe zimafunikira paukadaulo wa SMC insulation board

Bungwe la SMC lotchingira ndi chida chodziwika bwino cha insulation board. Kwa makasitomala omwe akufuna kugula, chinthu choyamba chomwe akufuna kuti amvetsetse ndizofunika zaukadaulo. Pokhapokha podziwa izi angapange chisankho choyenera. Chotsatira, tiyeni titsatire opanga akatswiri kuti timvetsetse zofunikira za SMC insulation board.

1. Insulation resistance ndi resistivity

Kukaniza ndiko kubwereza kwa conductance, ndipo resistivity ndiye kukana pa voliyumu ya unit. Zinthu zomwe sizimayendetsa bwino, zimakulitsa kukana kwake, ndipo ziwirizi zimakhala muubwenzi wofanana. Kwa zipangizo zotetezera, nthawi zonse zimakhala zofunidwa kukhala ndi resistivity yapamwamba kwambiri momwe zingathere.

2, chilolezo chachibale komanso kutayika kwa dielectric tangent

Zida zotetezera zili ndi ntchito ziwiri: kutsekemera kwa zigawo zosiyanasiyana za magetsi a magetsi ndi sing’anga ya capacitor (kusungirako mphamvu). Zakale zimafuna chilolezo chachibale chaching’ono, chotsiriziracho chimafuna chilolezo chachikulu chachibale, ndipo zonsezi zimafuna tangent yaing’ono ya dielectric, makamaka insulating zipangizo zomwe zimagwiritsidwa ntchito pafupipafupi komanso mphamvu zambiri, kuti kutayika kwa dielectric kukhale kochepa, zonse zimafuna kusankha Insulating. zakuthupi zokhala ndi tangent yaying’ono ya dielectric.

3, voteji yowonongeka ndi mphamvu yamagetsi

Zinthu zotchinjiriza zimawonongeka pansi pa gawo lina lamphamvu lamagetsi, ndipo zimataya magwiridwe antchito ndipo zimakhala zochititsa chidwi, zomwe zimatchedwa kuwonongeka. Mphamvu yamagetsi pa nthawi yowonongeka imatchedwa breakdown voltage (mphamvu ya dielectric). Mphamvu yamagetsi ndi quotient ya voteji pamene kusweka kumachitika nthawi zonse komanso mtunda wapakati pa ma elekitirodi awiri omwe amanyamula voteji yomwe imagwiritsidwa ntchito, yomwe ndi mphamvu yowononga pa makulidwe a unit. Ponena za insulating zipangizo, ambiri, ndi apamwamba kusweka voteji ndi mphamvu magetsi, bwino.

4, mphamvu yamanjenje

ndiye kupsinjika kosunthika komwe chitsanzocho chimakhala nacho pakuyesa kwamphamvu. Ndilo kuyesera kogwiritsidwa ntchito kwambiri komanso koyimilira kwa makina azinthu zotetezera.

5. Kukana kuyaka

amatanthauza kutha kwa zida zotetezera kukana kuyaka zikakumana ndi malawi kapena kuletsa kuyaka mosalekeza zikachoka. Pogwiritsa ntchito kuwonjezereka kwa zipangizo zotetezera, zofunikira za kukana kwawo moto ndizofunikira. Anthu asintha ndikuwongolera kukana kwa malawi kwa zida zoyatsira moto kudzera m’njira zosiyanasiyana. Kuchuluka kwa kukana kuyaka, kumakhala bwinoko chitetezo.

6, kukana kwa arc

Pazoyeserera pafupipafupi, mphamvu ya insulating imatha kupirira mphamvu ya arc pamtunda wake. Poyesera, magetsi a AC apamwamba ndi ang’onoang’ono amasankhidwa, ndipo mphamvu ya arc ya magetsi apamwamba pakati pa maelekitirodi awiriwa amagwiritsidwa ntchito kuti adziwe kukana kwa arc kwa insulating material panthawi yomwe imafunika kuti insulating ipange chosanjikiza. . Kuchuluka kwa nthawi, kumapangitsa kuti arc resistance.

7, digiri yosindikiza

Ndi bwino kusindikiza ndikupatula mafuta ndi madzi abwino.
