O le mea fa'alumaina o le afi e fuafua i le tele o le taimi nei po'o le voltage?

O le insulationmeafaitinoo le afi e fuafua i le tele o le taimi nei poʻo le voltage?

Mea fa'agataose mea autu taua mo oloa afi. O afi e eseese le maualuga o le voltage e iai le eseesega tele i le faʻaogaina o le faʻaogaina o latou faʻamalo ma o latou vaega autu. Mo se faʻataʻitaʻiga, o le faʻaogaina o le faʻaogaina o le eletise maualuga ma le maualalo o le uila afi e matua ese lava. .

Mea fa'amama, e lauiloa foi o le dielectrics, o mea ia e maualuga tele le tetee ma le leaga tele. O lo'o fa'aaogaina fo'i i mea tau afi ona o le le lelei o le amio. I oloa afi, e ala i mea faʻapipiʻi, i le tasi itu, o uaea conductive e fesoʻotaʻi ma isi vaega. O le vavaeeseina, i le isi itu, o le vavaeeseina lea o vaega eseese o le laina faʻatautaia, e pei o le faʻaogaina o le vaʻaia ma le faʻaogaina o le vaeluaga. E mafai fo'i ona iai mea fa'apitoa eseese e pei o le lagolago, fa'amauina, tineia o le arc, tete'e o le pala, puipuiga o le fa'avevela ma le fa'ama'i.

O le mu o uila afi o se faʻaaliga mautinoa o le faʻaleagaina poʻo le mou atu o le faʻaogaina o le faʻaogaina. Ma, o le faʻaogaina o le faʻaogaina o le afi ua faʻaleagaina ona o le tele o le faʻafefe o le taimi nei poʻo le maualuga maualuga?

When the motor winding current is too large, the higher current density will cause the winding resistance to increase and cause serious heat generation. The heat generated by the motor will be dissipated through the insulation. When the heat reaches a certain level, the structure of the insulating material will undergo qualitative changes, such as the motor The performance requirements of different insulation grades such as B, F, and H involved in the table correspond to the maximum working temperature that the mea fa'amamamafai ona tatalia.

For the motor winding, the insulation requirements between turns and turns, between different phases of a multi-phase motor, and between the conductor and the ground are involved. When the rated voltage of the motor is higher, the voltage of the winding insulation is also higher, which can be simply Think of this as different capacitors. If the voltage between the capacitors is too high, it will lead to the problem of capacitor breakdown, that is, the insulation failure of the motor winding to ground, between turns and between phases.

Mai le mea o loʻo i luga, e mafai ona tatou malamalama e ui lava o le taimi nei o le afi maualuga-voltage e laʻititi, o le voltage insulation o le viliina e maualuga, o lea e tatau ai ona faʻaogaina se fausaga faʻapitoa faʻapitoa e faʻamautinoa ai o le eletise o le afi e fetaui ma manaʻoga. ; aʻo le afi eletise maualalo, ona o le eletise eletise e maualuga tele O le mea lea, o le filifiliga o mea faʻapipiʻi e faigofie lava, ae o le taimi nei o le mamafa, faʻafefe ma le vevela o mea taua ia e faʻamautinoa ai le faʻaogaina o le eletise o le afi. O le taimi nei ma le voltage o le afi e eseese a'afiaga i lemea fa'amamama e tatau ona amanaia i le taimi lava e tasi.
