ZW20-12 lub tshuab nqus tsev vacuum breaker (tom qab no hu ua Circuit Court breaker) yog lub zog hluav taws xob sab nraum zoov hluav taws xob hloov pauv nrog qhov ntsuas zaus 50Hz thiab ntsuas qhov hluav taws xob 12kV. Nws yog tsuas yog siv rau qhib thiab kaw lub load tam sim no, overload tam sim no thiab luv luv Circuit Court tam sim no nyob rau hauv lub hwj chim system. Nws yog tsim rau cov kab nyiaj siv ua haujlwm thiab kev faib tawm txhua hnub ntawm kev lag luam thiab kev lag luam mining, tshwj xeeb tshaj yog tsim rau hauv nroog network thiab kev tsim kho vaj tse nyob hauv nroog.

Cov khoom thiab FTU nrog tau yooj yim paub txog kev tiv thaiv, ntsuas, tswj thiab kev sib txuas lus ua haujlwm. Nws tuaj yeem siv rau qhov kev faib tawm network uas nws qhov nruab nrab tsis yog hauv av, grounded los ntawm arc-absorbing coil lossis grounded los ntawm me me kuj.

Khoom zoo

ZW-20 lub tshuab nqus tsev vacuum breaker muaj ntau yam zoo:

1. Kev ua haujlwm yooj yim thiab yooj yim: cov khoom lag luam yog lub zog txuag hluav taws xob, hluav taws xob hloov hluav taws xob, thiab tib lub sijhawm, nws muaj cov khoom siv hluav taws xob cia, phau ntawv hloov pauv, thiab tuaj yeem ua haujlwm los ntawm cov chaw taws teeb tswj nyob ze lossis deb.

2. Kev ruaj ntseg sealing, txij nkawm-dawb: lub ntsiab ntawm lub Circuit Court breaker thiab lwm yam khoom, cov txheej txheem kev khiav hauj lwm yog tag nrho nyob rau hauv lub sealing, lub sealing qauv thiab technology yog mature thiab txhim khu kev qha.

3. Muaj kev nyab xeeb rau kev siv: Cov khoom tawg-pov thawj yog ntsia rau saum lub thawv, kom tsis txhob muaj kev phom sij ntawm kev tawg txawm tias muaj kev sib tsoo sab hauv.

4. Lub connector txais tub rog-qib aviation plug, ua los ntawm stainless hlau, nrog kub-plated pins; waterproof, huab cua to-pov thawj thiab txhim khu kev qha kev twb kev txuas.

5. Nws tuaj yeem kuaj xyuas qhov xoom ntu tam sim no ntawm kab ntawm milliampere theem thiab luv luv tam sim no ntawm theem ntawm 25 npaug ntawm tus nqi ntsuas, thiab siv microcomputer kom paub txog kev tiv thaiv, ntsuas thiab tswj kom raug, thiab kev ua rhiab heev.

6. Tus maub los tuaj yeem nruab nrog 485/232 kev sib txuas lus interface, fiber ntau optic lossis wireless kev sib txuas lus kom paub txog plaub qhov chaw taws teeb.

7. Cov khoom tuaj yeem tsim kev tiv thaiv, ntsuas tam sim no transformer, tib lub sijhawm tuaj yeem tsim-hauv xoom ntu tam sim no transformer, kom paub txog qhov kev tiv thaiv hauv av.

8. Circuit Court breaker plhaub tuaj yeem ua tau zoo carbon steel hmoov plhaub thiab stainless hlau plhaub tuaj yeem xaiv.

9. Controller plhaub qauv tuaj yeem ua tsis yog xim hlau tswb-hom qauv thiab hlau lub thawv-hom qauv tuaj yeem xaiv.
