Qhov Sib Txawv Ntawm High Voltage Load Switch Thiab High Voltage Circuit Breaker

Lub qhov hloov pauv hluav taws xob siab yog ib hom kev ua haujlwm ntawm lub tshuab hluav taws xob siab thiab lub qhov hloov pauv hluav taws xob siab, lub qhov hloov pauv hluav taws xob siab thiab lub fuse hluav taws xob siab feem ntau siv ua ke; Siv los tswj cov hloov pauv hluav taws xob. Lub qhov hloov pauv hluav taws xob siab muaj lub cuab yeej tua hluav taws xob yooj yim, yog li nws tuaj yeem tua qee qhov tam sim no thauj khoom thiab tam sim no overload. Txawm li cas los xij, nws tsis tuaj yeem txiav tawm tam sim no luv luv, yog li nws feem ntau siv ua ke nrog lub fuse hluav taws xob siab, nrog lub fuse rau kev tiv thaiv luv luv.

Cov lus txhais sib txawv:

Lub qhov hloov pauv hluav taws xob siab yog ib hom kev ua haujlwm ntawm lub tshuab hluav taws xob siab thiab lub qhov hloov pauv hluav taws xob siab, lub qhov hloov pauv hluav taws xob siab thiab lub fuse hluav taws xob siab feem ntau siv ua ke; Siv los tswj cov hloov pauv hluav taws xob. Lub qhov hloov pauv hluav taws xob siab muaj lub cuab yeej tua hluav taws xob yooj yim, yog li nws tuaj yeem tua qee qhov tam sim no thauj khoom thiab tam sim no overload.

Circuit breaker yog ib lub cuab yeej hloov uas tuaj yeem tua, nqa thiab tua tam sim no nyob rau hauv cov xwm txheej ib txwm muaj thiab tua, nqa thiab tua tam sim no nyob rau hauv cov xwm txheej tsis zoo hauv lub sijhawm teev tseg. Circuit breakers raug muab faib ua cov hluav taws xob siab thiab cov hluav taws xob qis raws li lawv qhov ntau ntawm kev siv. Kev faib ntawm cov ciam teb siab thiab qis hluav taws xob yog fuzzy. Feem ntau, cov neeg saum toj no 3kV hu ua cov khoom siv hluav taws xob siab.

Cov haujlwm sib txawv:

Lub tshuab hloov hluav taws xob siab yog qhov tsim nyog rau peb-theem AC 10KV, 50HZ fais fab system, lossis nrog cov khoom siv faib khoom tiav thiab lub nplhaib network switchgear, ua ke substation thiab lwm yam kev txhawb nqa, siv dav hauv kev tsim kho network thiab kev hloov pauv, kev lag luam thiab kev lag luam mining, cov tsev siab thiab cov chaw pej xeem, tuaj yeem siv ua lub nplhaib network fais fab mov lossis lub davhlau ya nyob twg, ua lub luag haujlwm ntawm kev faib hluav taws xob, kev tswj hwm thiab kev tiv thaiv. Nws muaj qhov zoo ntawm lub peev xwm tawg loj, kev nyab xeeb thiab txhim khu kev qha, lub neej hluav taws xob ntev, kev ua haujlwm ntau zaus, cov qauv me me, me me, lub teeb yuag, thiab tsis tas yuav tsum tau saib xyuas. Nrog off-rated tam sim no, overload tam sim no. Nws tuaj yeem tawg lub luv luv Circuit tam sim no thiab tiv thaiv cov khoom siv los ntawm kev khiav tsis muaj theem. Lub qhov hloov pauv muaj qhov tawg cais pom tseeb. Nws muaj lub tshuab hluav taws xob caij nplooj ntoos hlav hloov av nrog lub peev xwm kaw, uas tuaj yeem tswj tau deb thiab deb.

Cov cuab yeej hluav taws xob siv tau los faib hluav taws xob, pib cov cav asynchronous tsis tshua muaj, tiv thaiv cov kab hluav taws xob thiab cov cav, thiab txiav lub voj voog thaum lawv muaj qhov teeb meem loj heev, luv luv thiab tsis muaj zog. Lawv cov haujlwm zoo ib yam li kev sib xyaw ua ke ntawm fusing switch thiab over thiab under thermal relay. Thiab feem ntau tsis tas yuav hloov cov khoom tom qab txiav qhov teeb meem tam sim no. Tam sim no, nws tau siv dav.
