Khoom siv

Cov khoom zoo thiab qhov tsis zoo

1. iav insulator

Qhov zoo: lub zog txhua yam ntawm txheej txheej ntawm iav insulator yog siab, qhov saum npoo tsis yooj yim rau tawg, thiab kev laus qeeb qeeb;Nws tuaj yeem tshem tawm qhov kev tiv thaiv nyob ib ntus ntawm cov insulators thaum lub sijhawm ua haujlwm, thiab tsis tas yuav tsum tau ua "zero value" nrhiav tau thaum lub sijhawm ua haujlwm, yog li kev ua haujlwm thiab kev saib xyuas tus nqi qis.

Disadvantages: vim lub pob tshab ntawm iav, nws yog ib qho yooj yim mus nrhiav tau cov kab nrib pleb me me thiab ntau yam sab hauv thiab kev puas tsuaj thaum lub sij hawm soj ntsuam.

2. Ceramic insulator

Qhov zoo: zoo tshuaj stability thiab thermal stability, muaj zog tiv thaiv kev laus muaj peev xwm, zoo hluav taws xob thiab txhua yam khoom, thiab hloov tau los ua ke.

Qhov tsis zoo: qhov tsis xws luag tsis yooj yim pom, thiab lawv pib pom tsuas yog tom qab ob peb xyoos ntawm kev ua haujlwm;Kev txheeb xyuas tus nqi xoom ntawm ceramic insulators yuav tsum tau nqa tawm ib los ntawm ib qho ntawm cov pej thuam, uas yuav tsum muaj ntau tus neeg ua haujlwm thiab cov khoom siv;Qhov tshwm sim ntawm cov xwm txheej tshwm sim los ntawm xob laim stroke thiab muaj kuab paug flashover yog siab.

3. Composite insulator

Qhov zoo: me me, kev saib xyuas yooj yim;Lub teeb yuag thiab yooj yim installation;Lub zog txhua yam, tsis yooj yim tawg;Zoo heev seismic kev ua tau zoo thiab muaj kuab paug tsis kam;Lub voj voog ntau lawm ceev thiab zoo stability.

Qhov tsis zoo: muaj peev xwm tiv thaiv kev laus tsis zoo li ceramic thiab iav insulators, thiab cov nqi tsim khoom yog siab dua li cov ceramic thiab iav insulators.
