Txhaum Kev Tawm Ntawm Cov Npe Siab Highgt Switchgear Thiab Nws Ua

Survey statistics qhia tau hais tias lub ntsiab faults ntawm high voltage switchgear yog raws li nram no:

(1) Rejection los yog kev ua hauj lwm tsis ua hauj lwm: Hom kev txhaum no yog lub ntsiab txhaum cai ntawm lub siab hloov qhov hluav taws xob. Vim li cas thiaj yuav muab faib ua ob pawg: ib qho yog vim tsis yog kev ua hauj lwm ntawm kev khiav hauj lwm mechanism thiab kev sib kis kab mob; lwm qhov yog vim yog ua los ntawm cov hluav taws xob tswj thiab cov ntu kev pab cuam.

(2) Txhawm thiab kaw cov kev ua yuam kev: Cov kev ua txhaum no yog vim los ntawm lub cev lub plhaub ntawm lub voj voog. Rau cov khoom siv roj rau cov roj, qhov kev ua haujlwm tseem ceeb yog lub sijhawm luv luv ntawm kev siv roj, kev tua hluav taws xob, kev tawg tsis txaus, thiab kaw tawg, thiab lwm yam. Rau lub tshuab nqus tsev rau lub tshuab nqus tsev, nws yog cov pa tawm ntawm lub nkoj extinguishing chamber thiab cov ntswg, txo qis, rov tua hluav taws xob ntawm cov pabcuam capacitor capacitor, thiab tawg ntawm lub qhov cub hlau.

(3) Hluav taws xob thaiv hluav taws xob: kev ua haujlwm sab nraud thaiv mus rau hauv av flashover, qhov hluav taws xob nyob rau hauv av flashover, kev hloov theem-rau-phom flashover, xob laim overvoltage flashover kev ploj, porcelain fwj casing, capacitor casing flashover, pa paug, kev sib tsoo, tawg , tshem phom flashover, iav flashover, kev sib tawg, tawg, plooj (veneers) fais fab tuag.

(4) Kev txhaum tam sim no: Lub ntsiab tseem ceeb ntawm kev txhaum tam sim no ntawm 7.2 ~ 12 kV voltage yog tias qhov kev sib txuas ntawm cov hlua txuas hluav taws xob ua rau kev sib tiv tauj rau yaj.

(5) Sab nraud rog thiab lwm yam kev yuam kev: nrog rau kev cuam tshuam dab tsi txawv teb chaws, natural disasters, tsiaj nyhuv me me, thiab lwm yam.
