Chishandiso chemagetsi chine simba guru chinoshandiswa pakubatanidza magetsi ane simba guru, chine chinobvisa magetsi, fuse, thermal relay, shunt release uye arc extinguishing device.

Chishandiso chemagetsi ane simba guru chine mudziyo uri nyore wekudzima arc, unogona kungoshandiswa kugadzira nekupwanya simba remagetsi rakajairika, uye haugone kushandiswa kupwanya simba remagetsi ane simba guru. Saka, simba remagetsi rine simba guru rinowanzoenderana nefuse ine simba guru uye kuburitswa kwemafuta, uye fuse inoshandiswa kudimbura simba remagetsi ane simba guru panguva yekushanda kwemagetsi madiki. Kana paine kuwanda kwemagetsi, simba remagetsi rinoita kuti switch yemagetsi ipinde otomatiki. Sezvo paine mukaha uri pachena kana switch yemagetsi yabviswa, inewo basa rekuparadzanisa simba remagetsi kuti ive nechokwadi chekuti magetsi akachengetedzwa zvakanaka.

Swichi yemagetsi ine simba guru uye midziyo yemagetsi yakabatana yakakodzera masisitimu emagetsi eAC 10 kV, 50 Hz, kana kushandiswa pamwe chete nemidziyo yakazara yekuparadzira magetsi, makabati eringi network, zviteshi zvemagetsi zvakabatana, nezvimwewo, uye zvinoshandiswa zvakanyanya mumapurojekiti ekuvaka nekugadzirisa network, mabhizinesi emaindasitiri nekuchera migodhi, zvivakwa zvepamusoro nenzvimbo dzeveruzhinji, nezvimwewo, zvinogona kushandiswa seringi network yemagetsi kana terminal, uye zvinotamba basa rekugovera magetsi, kudzora nekudzivirira. Ine mabhenefiti ehukuru hwekutyoka, kuchengetedzeka nekuvimbika, hupenyu hwemagetsi hurefu, kushanda nguva dzose, chimiro chakamanikana, saizi diki, huremu hushoma, uye zvachose hapana kugadziriswa. Neringi yakayerwa kutyoka, overload current. Inogona kutyora short-circuit current uye kudzivirira kushanda kwemidziyo kubva pakushaikwa kwechikamu. Swichi ine kutyoka kuri pachena. Yakashongedzerwa nemagetsi echitubu cheswichi yekumisa pasi ine kugona kwekuvhara, iyo inogona kudzorwa kure.

Chinochinja load (QL) iswitchgear yakatsaurirwa kugadzira nekupwanya ma load currents. Chinochinja load charge chine arc extinguisher chiri nyore uye chinobvisa load current pachena, chinogona kubatidza nekudzima load current uye overload current, uye chine basa re isolation switch, asi hachikwanise kubvisa short-circuit current. Kazhinji, fekitori ye load switch inoshandiswa pamwe chete nemafuse kudimbura fault current nerubatsiro rwemafuse, ayo anogona kushandiswa zvakanyanya mukuvakazve power grid muguta uye kumaruwa. Inonyanya kushandiswa pa 6~10kV power grid.

Zvichienderana nechinhu chinodzima moto che arc, switch ine simba guru inokamurwa kuva mhando yekugadzira gasi, mhando yegasi rakamanikidzwa, mhando ye vacuum uye mhando ye SF6. Zvichienderana nenzvimbo yekuisa, yakakamurwa muzvikamu zviviri: mhando yemukati neyekunze.

Chishandiso chekutakura zvinhu chakareruka, chidiki uye chine mutengo wakaderera, uye chakakodzera zviitiko zvisingade mafuta, zvisingagadziriswe, uye zvinoshandiswa kakawanda. Pamwe chete nemafuse, inogona kushandiswa sechishandiso chemagetsi kune vashandisi vane kugona kudiki kana kusina kukosha kwekutsiva macircuit breakers. Chishandiso chekutakura zvinhu chinosarudzwa zvichienderana nevoltage yakatarwa uye current yakatarwa, uye chinoongororwa kuti chinodzvanywa here uye kuti chinogadzikana sei. Kana chakashongedzerwa nefuse, kugona kutyoka kwefuse kunofanirwa kuongororwa, uye kugadzikana kwayo kwesimba uye kupisa kunogona kusaongororwa.
