1. Ukwakhiwa kwekhabhinethi yokushintsha:
I-switchgear izohlangabezana nezidingo ezifanele zezinga le-GB3906-1991 “3-35 kV AC Metal-enclosed Switchgear”. Yakhiwe yikhabhinethi kanye ne-circuit breaker, futhi inemisebenzi efana nezintambo ezingenayo neziphumayo eziphezulu, izintambo ezingenayo neziphumayo, kanye noxhumo lwebhasi. Ikhabhinethi yakhiwe igobolondo, izakhi zikagesi (kuhlanganise nama-insulators), izindlela ezihlukahlukene, amatheminali esibili kanye nokuxhuma.
★ Izinto zeKhabhinethi:
1) Ipuleti lensimbi eligoqiwe elibandayo noma insimbi ye-engeli (yekhabhinethi yokushisela);
I-2) Ishidi lensimbi eliboshwe i-Al-Zn noma ishidi lensimbi (elisetshenziselwa ukuhlanganisa amakhabethe).
3) Ipuleti lensimbi engagqwali (okungelona uzibuthe).
4) Ipuleti le-Aluminium ((okungelona uzibuthe).
★ Iyunithi yokusebenza yekhabhinethi:
1) Igumbi lebhasi eliyinhloko (ngokuvamile, isakhiwo sebha yebhasi enkulu sinezakhiwo ezimbili: umumo “wephini” noma umumo othi “1″
2) Igumbi le-circuit breaker
3) Igumbi lekhebula
4) Igumbi lokudlulisa kanye nensimbi
5) Igumbi elincane lebhasi phezulu kwekhabhinethi
6) Igumbi letheminali yesibili
★ Izingxenye zikagesi kukhabhinethi:
1.1. Izingxenye zikagesi ezisetshenziswa kakhulu (imishini yesekethe enkulu) ekhabetheni zifaka le mishini elandelayo:

Ibhasi eliyinhloko nebhasi legatsha
I-high voltage reactor [njengohlobo lochungechunge: CKSC kanye nohlobo lwemoto yokuqala: QKSG]
Iswishi yokulayisha [isb. FN26-12(L), FN16-12(Z)]
I-high-voltage single-phase shunt capacitor [njenge: BFF12-30-1] njll.
1.2. Izingxenye zesibili eziyinhloko ezivame ukusetshenziswa kwikhabhinethi (ezaziwa nangokuthi izisetshenziswa zesibili noma izinsimbi ezisizayo, zibhekisela emishinini yamandla aphansi eqapha, elawulayo, ekalayo, elungisa futhi evikela imishini eyinhloko), lezi ezivamile yilezi mishini elandelayo:
1.I-Relay 2. Imitha kagesi 3. I-Ammeter 4. Imitha ye-voltage 5. Imitha yamandla 6. Imitha yesici samandla 7. Imitha ye-frequency 8. I-Fuse 9. I-air switch 10. I-switch-over switch 11. Isilambu sesignali 12. Ukuphikiswa 13. Inkinobho 14 . Idivayisi yokuvikela ehlanganisiwe ye-Microcomputer nokunye.
2. Ukuhlelwa kwamakhabethe okushintsha amandla kagesi aphezulu:
2.1. Ngokwendlela yokufaka ye-circuit breaker, ihlukaniswe ngohlobo olukhiphekayo (uhlobo lwenqola ephathwayo) kanye nohlobo olungaguquki.
(1) Uhlobo olukhishwayo noma lwenqola ephathwayo (ekhonjiswe ngu-Y): Kusho ukuthi izingxenye zikagesi eziyinhloko (njengama-circuit breaker) ekhabetheni zifakwe enqoleni engakwazi ukuhoxiswa, ngoba amakhabhinethi enqola ashintshana kahle Ngakho-ke, angakwazi ngcono kakhulu ukwethembeka kokunikezwa kwamandla. Izinhlobo ezivame ukusetshenziswa kakhulu zezinqola zezandla yilezi: izinqola ezizihlukanisayo, izinqola ezilinganisa amamitha, izinqola ze-circuit breaker, izinqola zezandla ze-PT, izinqola zesandla ezine-capacitor nezinqola ezisetshenziswayo, njenge-KYN28A-12.
(2) Uhlobo olungaguquki (oluboniswa ngu-G): Lubonisa ukuthi zonke izingxenye zikagesi (njengama-circuit breaker noma amaswishi okulayisha, njll.) ekhabetheni zifakwe ngokuqinile, futhi ama-switch cabinets alula futhi ayonga, njenge-XGN2-10. , GG- 1A njll.
2.2. Ihlukaniswe ngaphakathi nangaphandle ngokuya ngendawo yokufaka
(1) Isetshenziswa endlini (ekhonjiswe ngu-N); kusho ukuthi ingafakwa futhi isetshenziswe endlini kuphela, njenge-KYN28A-12 namanye amakhabethe okushintsha;
(2) Kusetshenziswe ngaphandle (okuboniswa ngu-W); kusho ukuthi ingafakwa futhi isetshenziswe ngaphandle, njenge-XLW namanye amakhabethe okushintsha.
3. Ngokusho kwesakhiwo sekhabhinethi, ingahlukaniswa ngezigaba ezine: i-switchgear eboshwe ngensimbi, i-switchgear ehlanganiswe nensimbi ehlanganiswe nensimbi, i-switchgear yebhokisi evalwe ngensimbi, kanye ne-open-type switchgear.
(1) Imishini yokushintsha insimbi evalwe ngensimbi (ekhonjiswe ngohlamvu K) Izingxenye eziyinhloko (njengama-circuit breaker, ama-transformer, amabhasi amabhasi, njll.) zifakwe ezindaweni ezivalekile zensimbi zezingxenye eziphansi ezihlukaniswe izingxenye zensimbi. Shintsha imishini. Okufana ne-KYN28A-12 uhlobo lwekhabethe lokushintshwa kwamandla kagesi.
(2) I-switchgear yekhompathi evalwe ngensimbi (ekhonjiswe ngohlamvu J) ifana ne-armored metal-enclosed switchgear, futhi izingxenye zayo eziyinhloko zikagesi nazo zifakwe ezingxenyeni ezihlukene, kodwa zinezinga elithile lokuvikela elilodwa noma ngaphezulu I-Non-metallic. ukwahlukanisa. Okufana ne-JYN2-12 uhlobo lwekhabhinethi yokushintsha kagesi ephezulu.
(3) I-Switchgear yensimbi evalelwe-yohlobo lwebhokisi (ekhonjiswe ngohlamvu X) Igobolondo le-switchgear iyi-switchgear evalwe ngensimbi. Njenge-XGN2-12 high voltage switch cabinet.
(4) I-switchgear evulekile, akukho mfuneko yezinga lokuvikela, ingxenye yegobolondo iyi-switchgear evulekile. Njenge-GG-1A (F) high voltage switch cabinet
