400kV 210kN Ntev Qws Silicone Rubber Insulator

1) Corona Discharge: Cua ionization ua rau lub teeb xiav thiab lub suab nrov nrov. Ntev - lub sij hawm corona tso tawm yuav:

Corrode lub silicone roj hmab nto, accelerating aging, pulverization, thiab tawg;

Tsim cov ozone thiab nitrogen oxides, corroding cov tub ntxhais pas nrig thiab haum interface, ua rau lub interface dej seepage thiab tub ntxhais qws brittle puas.

2) Hauv zos Arcing, Dry Area Arcing: Hauv huab cua los nag lossis huab cua, cov ntaub ntawv dej ua rau ntawm qhov chaw insulator. Cov cheeb tsam uas muaj qhov muaj zog muaj zog tuaj yeem ua rau thaj chaw qhuav arcing, rov hlawv cov roj hmab silicone, ua rau lub qhov ablation, ncaj qha txo cov rwb thaiv tsev lub zog, thiab txawm flashover tripping.

Muaj nuj nqi ntawm Corona Rings
Hlau nplhaib conductor lub tes tsho yog ntsia rau ntawm qhov siab -voltage kawg (ob qhov kawg yog ntsia rau qee qhov chaw muaj kuab paug):
Lawv uniformly faib cov concentrated hluav taws xob teb ntawm tus neeg xyuas pib sab, smoothing lub peev xwm gradient;
Lawv txo qhov hluav taws xob sab hauv lub zog ntawm thawj lub tsev, suppressing corona thiab arcing;

400kV tus qauv yuav tsum tau: Qhov siab tshaj plaws hluav taws xob teb lub zog thaum kawg yuav tsum tau tswj tsis pub dhau 22kV / cm. Yog tsis muaj lub nplhaib sib npaug, nws yuav dhau tus qauv los ntawm 3 mus rau 5 zaug.

Noog- pov thawj Ring Structure thiab Principple
Feem ntau ntsia rau ntawm qhov kawg ntawm cov insulator (ntauwd sab), hlau disc / nplhaib baffle:
Blocks droppings: Thaum ib tug noog tsaws rau ntawm lub crossarm, nws cov tee poob vertically thiab raug thaiv los ntawm lub nplhaib hlau, tiv thaiv lawv los ntawm ntws raws li insulator tiab thiab txiav tawm cov conductive kab mob;
Tiv thaiv perching: Lub annular tsa disc lub concave / sab nraud-fab tsim tiv thaiv cov noog los ntawm kev ruaj khov ntawm cov khoom siv sab saum toj ntawm lub rwb thaiv tsev, txo lub sij hawm siv ncua mus rau defecate;
Ua kom qhov sib txawv ntawm huab cua: Lub disc txuas mus rau sab nraud, ua kom muaj kev tiv thaiv zoo ntawm cov noog lub cev thiab lub siab -voltage conductor, tiv thaiv luv luv - Circuit Court paug thaum tis kis tau.
