Bhazi guru uye bhazi rebazi
Yakakwira voltage reactor [senge akateedzana mhando: CKSC uye yekutanga mota mhando: QKSG]
Load switch [eg FN26-12(L), FN16-12(Z)]
Yakakwira-voltage single-phase shunt capacitor [yakadai se: BFF12-30-1] nezvimwe.
1.2. Iwo makuru echipiri echikamu anowanzo shandiswa mukhabhineti (inozivikanwawo seyechipiri midziyo kana yekubatsira midziyo, inoreva yakaderera-voltage midziyo inotarisisa, inodzora, nhanho, inogadzirisa uye inodzivirira yekutanga michina), izvo zvakajairika ndezvinotevera zvishandiso:
1.Relay 2. Magetsi mita 3. Ammeter 4. Voltage mita 5. Power meter 6. Power factor meter 7. Frequency mita 8. Fuse 9. Air switch 10. Change-over switch 11. Signal lamp 12. Resistance 13. Bhatani 14 . Microcomputer yakabatanidzwa kudzivirira mudziyo uye zvichingodaro.
2. Kurongwa kweakakwira voltage switch makabati:
2.1. Zvinoenderana neiyo yekumisikidza nzira yedunhu breaker, yakakamurwa kuva inobviswa mhando (handcart type) uye yakatarwa mhando.
(1) Inobviswa kana handcart type (inoratidzwa naY): Zvinoreva kuti zvinhu zvikuru zvemagetsi (zvakadai semabreaker breaker) mukhabhineti zvakaiswa pane handcart inogona kubviswa, nekuti handcart cabinets inochinjana saka, inogona kuvandudza zvakanyanya kuvimbika kwesimba rekupa. Mhando dzinowanzo shandiswa dzezvikochikari zvemaoko ndeidzi: zvikochikari zvemaoko, zvingoro zvemamita, zvikero zvemawoko zvinopwanya, PT handcart, capacitor handcart uye ngoro dzemaoko dzinoshandiswa, seKYN28A-12.
(2) Fixed type (inoratidzirwa naG): Inoratidza kuti zvinhu zvose zvemagetsi (zvakadai semagetsi emagetsi kana mashizha emagetsi, nezvimwewo) mu cabinet zvakaiswa zvakagadziriswa, uye makabati ekugadzirisa akagadziriswa ari nyore uye ane mari, akadai se XGN2-10 , GG-1A nezvimwewo.
2.2. Yakakamurwa mukati uye kunze zvichienderana nenzvimbo yekuisa
(1) Inoshandiswa mumba (inoratidzirwa naN); zvinoreva kuti inogona kuiswa chete uye kushandiswa mukati, yakadai seKYN28A-12 uye mamwe makabati ekuchinja;
(2) Inoshandiswa kunze (inoratidzirwa naW); zvinoreva kuti inogona kuiswa uye kushandiswa kunze, yakadai seXLW uye mamwe makabati ekuchinja.
3. Zvinoenderana nechimiro chekhabhineti, inogona kukamurwa kuita zvikamu zvina: simbi-yakavharirwa armored switchgear, simbi-yakavharirwa compartmental switchgear, simbi-yakavharirwa bhokisi-mhando switchgear, uye yakavhurika-mhando switchgear.
(1) Metal-yakavharirwa armored switchgear (inoratidzwa netsamba K) Zvikamu zvikuru (zvakadai semavhiriki ematunhu, ma transformer, mabhawa ebhazi, nezvimwewo) zvakaiswa mumatanda esimbi emakamuri akadzika akaparadzaniswa nematare esimbi. Chinja midziyo. Zvakadai seKYN28A-12 mhando yakakwira voltage switch kabati.
(2) Metal-yakavharirwa compartmental switchgear (inoratidzwa netsamba J) yakafanana nesimbi yakavharidzirwa-yakavharirwa switchgear, uye zvikamu zvayo zvemagetsi zvakaiswawo mumakamuri akasiyana, asi iine imwe kana kupfuura yeimwe dhigirii yekudzivirira Non-metallic. partition. Zvakadai seJYN2-12 mhando yakakwira voltage switch kabati.
(3) Metal-yakavharwa bhokisi-mhando switchgear (inoratidzwa netsamba X) Iyo shell ye switchgear isimbi-yakavharwa switchgear. Zvakadai seXGN2-12 yakakwira voltage switch kabati.
(4) Vhura switchgear, hapana chekudzivirira chikamu chinodiwa, chikamu chegoko chakavhurika switchgear. Zvakadai seGG-1A (F) high voltage switch cabinet
