Ratidza nzvimbo yekuisa uchishandisa mabhii;

N: Magadzirirwo emukati

W: Maitiro ekunze;

Ratidza nhamba ye serial yakagadzirwa, inomiririrwa nenhamba;

Kuratidza voltage yakayerwa (muKV, kV);

Hunhu hwebasa rekuwedzera, hunomiririrwa netsamba;

G Rudzi Rwakavandudzwa

F: Kushanda kwekupatsanurana kwechikamu;

Inoratidza simba remagetsi rakayerwa (chikamu: A);

Kuratidza kugona kuputsa kwakayerwa (MVA) kana kuputsa kwemagetsi (KA);

Semuenzaniso, modhi ye "high-voltage circuit breaker" ndiyo ZN10-10/300-750, iyo inomiririra Muchina weVacuum Circuit Breaker wemukati ine nhamba yedhizaini yegumi, voltage yakayerwa ye10KV, current yakayerwa ye300A, uye kugona kwayo kuputsa 750MVA kwakayerwa.

Main technical parameters
Voltage yakayerwa: zvinoreva voltage inoshanda yakajairika iyo circuit breaker inogona kutsungirira. Voltage yakayerwa inoreva voltage yemutsara.

Zvichienderana nemitemo yenyika, mwero wemagetsi akayerwa unosanganisira 10KV, 35KV, 60KV, 110KV, 220KV, 330KV, uye 500KV.

Voltage yepamusoro yekushandisa: Tichifunga nezvekudonha kwevoltage yetambo yekutumira, voltage yakayerwa yebhasbar pamagumo emagetsi etambo yakakwira kupfuura voltage yakayerwa yebhasbar pamagumo ekugamuchira magetsi, saka circuit breaker inogona kushanda kwenguva yakareba pavoltage yakakwira kupfuura voltage yakayerwa. Saka, zvinotarisirwa kuti circuit breaker ine voltage yepamusoro yekushandisa.

Zvichienderana nezvinodiwa nenyika, pamidziyo ine voltage ine 220KV kana pasi, voltage yepamusoro inoshanda i1.15 yakapetwa pane voltage yakarongwa. Pamidziyo ye330KV, inotarisirwa kuva 1.1.

Rated current: zvinoreva simba remagetsi rinoshanda iro circuit breaker rinoratidzwa pazita remagetsi rinogona kupfuura nepakati paro kwenguva yakareba.

Rated breaking current: Mwenje wepamusoro unogona kuchekwa ne circuit breaker pa voltage yakayerwa. Inonzi rated breaking current. Inoratidza kugona kwe circuit breaker.

Nguva yekugumisa: Kune macircuit breaker ane mashandiro ekushanda, nguva inodiwa kubva panguva iyo chiratidzo chekuvhara chaburitswa (kureva kuti coil yekuvhara inoshandiswa nevoltage) kusvika circuit breaker yavhurwa. Kazhinji, nguva yekuvhara yakakura kupfuura nguva yekuvhura.

Nguva yekuvhura: zvinoreva nguva yose inodiwa kubva pakuburitswa kwechiratidzo chekugumburwa (voltage inoshandiswa pacoil yekugumburwa) kusvika pakubviswa kwecircuit breaker kusvika arc yechikamu chetatu yadzimwa zvachose. Nguva yekuvhurwa kazhinji iri pakati pemasekondi 0.03 nemasekondi 0.12.

Hunhu hwemafuta/Vacuum Circuit Breakers

Mhando mbiri dzinonyanya kushandiswa dzinoti oil circuit breakers ne vacuum circuit breakers. Dzinounzwa seinotevera:

1. Chinopwanya dunhu remafuta: Inogona kukamurwa kuita mhando mbiri: mhando yemafuta akawanda uye mhando yemafuta mashoma. Nekuda kwehukuru hwayo uye kusagadziriswa kwayo kwakaoma, kugadzirwa kwema "multi oil circuit breakers" kwamira zvachose. "Low oil circuit breaker" ine "low volume", "hombe breaker", uye "strong structure", uye inoshandiswa mu "substations" dzemukati nekunze dzine ma "voltage" akasiyana. Parizvino, "indoor SN10-10 low oil circuit breaker" inoshandiswa zvakanyanya pa10KV, "indoor SN4-35" ye35KV, "outdoor SW4-35" yemhando, uye "SW6-110" yemhando ye110KV. "Goko" rine magetsi, saka zvakakosha kutarisisa "insulation" iri pakati pegoko nepasi panguva yekuisa.

mufananidzo

2. Muchina wekupwanya dunhu remagetsi: Imhando itsva yemuchina wekupwanya magetsi une simba guru wakagadzirwa muma1960 (sezvakaratidzwa pamufananidzo uri pakutanga kwechinyorwa chino semuchina wekupwanya magetsi une simba guru weZN28-12), unoshandisa muchina wekupwanya magetsi kudzima ma arc. Zvakanakira zvinosanganisira saizi diki, huremu hushoma, kukurumidza kushanda, kudzivirira moto nekuputika, uye ruzha rwakaderera. Pari zvino pane tsika yekutsiva mamwe ma circuit breaker, anonyanya kushandiswa mu substations dziri pasi pe35KV nenzvimbo dzinodiwa kushanda nguva nenguva mumaindasitiri nemakambani emigodhi.
