Raws li cov qauv hluav taws xob thoob ntiaj teb thiab cov xwm txheej siv tau zoo, Surge Protective Devices tau muab faib ua hom sib txawv nrog cov yam ntxwv ua tau zoo thiab cov ntawv thov ntau yam, uas tau piav qhia hauv qab no:
1. Hom 1 Surge Protective Devices
Hom 1 SPDs yog tsim los tiv thaiv kev tiv thaiv hluav taws xob thawj zaug. Lawv raug ntsia rau ntawm lub ntsiab fais fab ntawm cov tsev, substations, thiab loj industrial fais fab faib chaw. Lawv tuaj yeem tiv taus thiab tso tawm cov hluav taws xob siab heev tam sim no, tiv thaiv hluav taws xob ncaj qha thiab muaj zog cuam tshuam xob laim. Lawv cov txiaj ntsig tseem ceeb yog qhov muaj peev xwm tawm tam sim no loj, uas tuaj yeem tso tawm megaampere- theem xob laim, muab thawj kab kev tiv thaiv rau cov tshuab hluav taws xob.
2. Hom 2 Surge Protective Devices
Raws li cov cuab yeej tiv thaiv nruab nrab ntawm lub zog hluav taws xob, Hom 2 SPDs tau teeb tsa hauv cov thawv xa khoom hauv pem teb thiab lub rooj cob qhia ceg fais fab. Lawv feem ntau suppress residual overvoltage tom qab hom 1 tiv thaiv thiab nqus cov pa hluav taws xob hloov pauv surges thiab thauj khoom hloov pauv. Lawv muaj qhov zoo tshaj plaws voltage clamping kev ua tau zoo thiab nruab nrab tam sim no tso tawm muaj peev xwm, ua hauj lwm raws li lub hauv paus ntsiab lus tiv thaiv ntaus ntawv rau feem ntau lub hwj chim tis systems.
3. Hom 3 Surge Protective Devices
Hom 3 SPDs yog cov khoom siv tiv thaiv zoo, ntsia ncaj qha rau pem hauv ntej ntawm cov khoom siv hluav taws xob, khoos phis tawj, PLC cov cuab yeej, thiab cov chaw sib txuas lus. Lawv tsis tuaj yeem dais qhov loj tam sim no tab sis muaj ultra- qhov hluav taws xob qis qis thiab cov lus teb ceev heev, uas tuaj yeem tshem tawm cov kev cuam tshuam me me uas tsis tuaj yeem cuam tshuam los ntawm Hom 1 thiab Hom 2 SPDs, tiv thaiv siab - cov cuab yeej rhiab heev los ntawm kev puas tsuaj hluav taws xob.
4. Fais fab SPD thiab teeb liab SPD
Fais fab SPDs yog siv rau AC thiab DC fais fab kev tiv thaiv Circuit Court, hloov mus rau lub zog zaus voltage surges ntawm lub hwj chim faib systems. Cov teeb liab SPDs yog tsim tshwj xeeb rau cov kab hluav taws xob tsawg-voltage signals transmissions xws li network cables, xov tooj, thiab sensor kab. Lawv muaj cov teeb liab qis attenuation thiab siab tiv thaiv - cuam tshuam kev ua haujlwm, ua kom cov teeb liab sib kis tau zoo thaum ua tiav kev tiv thaiv surge.
5. Tsev thiab Industrial SPDs
SPDs hauv tsev yog qhov me me, qis- cov khoom siv hluav taws xob rau cov tshuab hluav taws xob hauv tsev, nrog cov haujlwm yooj yim thiab tus nqi qis. Kev lag luam SPDs yog siab-kev ua tau zoo, siab- cov khoom siv muaj kev ntseeg siab nrog cov dej tsis zoo, plua plav, tawg- pov thawj, thiab thermal tiv thaiv kev ua haujlwm, tsim nyog rau qhov chaw ua haujlwm nyuaj thiab hnyav zog.
