Kodi Kusiyana Pakati pa Zipangizo Zoteteza Mtundu 1 + 2 ndi Mtundu 2?

Kumvetsetsa Chipangizo choteteza ma surge cha mtundu wa 1+2 poyerekeza ndi mtundu wa 2 Kusiyanitsa ndikofunikira popanga njira yogwira ntchito njira yotetezera mafunde amagetsiMitundu yosiyanasiyana ya zipangizo zoteteza ma surge protective (SPD) yapangidwa kuti igwire ntchito zinazake zokhudzana ndi ma surge, makamaka mafunde a mphezi ndi ma switching transients.

Mu zomangamanga zamakono zogawa magetsi, mainjiniya nthawi zambiri amagwiritsa ntchito Mtundu Wophatikizana 1+2 SPD pakhomo lolowera kuti muteteze ku mphepo yamphamvu yamagetsi, pomwe Zipangizo zodzitetezera ku ma surge a mtundu wa 2 nthawi zambiri zimayikidwa m'magawo ogawa omwe ali pansi pamadzi.

Malo opangira mafakitale, nyumba zamalonda, ndi makina ogwiritsira ntchito mphamvu zongowonjezwdwanso nthawi zambiri amaphatikiza mitundu yonse iwiri ya zida ngati gawo la dongosolo loteteza mafunde otuluka m'madzi kuonetsetsa kuti pali chitetezo chogwirizana pa netiweki yonse yamagetsi.

Zitsanzo za njira zodzitetezera zomwe zimakhala ndi mphamvu zambiri zitha kuwoneka mu Mapangidwe a chipangizo choteteza kugwedezeka kwa mtundu wa 1 + 2 amagwiritsidwa ntchito poika malo olowera ntchito.

Kodi Mitundu Yophatikizana ya 1 + 2 SPDs Imathana Bwanji ndi Mphezi ndi Kusintha kwa Mafunde?

A Mtundu Wophatikizana 1+2 SPD imagwirizanitsa ntchito ziwiri zoteteza mu chipangizo chimodzi:

• Mphamvu yotulutsa mphamvu ya mphezi (Mtundu 1)

• Kuchepetsa mphamvu yamagetsi kuchokera ku ma surges osinthira (Mtundu 2)

Kuphatikiza kumeneku kumalola chipangizochi kugwira ntchito ngati chipangizo choteteza mphezi wokhoza kuyendetsa bwino mafunde akuluakulu oyendetsedwa ndi mphezi mwachindunji kapena pafupi.

Chitetezo cha Mphezi

Pa nthawi ya mphezi, choletsa magetsi a mphezi iyenera kuthana ndi mafunde a impulse omwe afotokozedwa ndi mayeso a waveform a 10/350 μs omwe amagwiritsidwa ntchito mu Chipangizo choteteza kugwedezeka kwa IEC 61643-11 miyezo.

Ma SPD amtundu wa 1 + 2 amatha kutulutsa mafunde amphamvu awa popanda kuwononga zida zotsikira pansi.

Kuteteza Kuthamanga Kwambiri

Kusintha kwa mafunde kumayambira pa:

• kusinthana kwa transformer

• zochitika zoyambira/kusiya magalimoto

• kusinthana kwa banki ya capacitor

• kusokonezeka kwa gridi

Gawo lotetezedwa la Mtundu Wachiwiri lophatikizidwa limachepetsa mphamvu yamagetsi yotsalira, kuonetsetsa kuti zida zomvera zimalandira mphamvu yokhazikika.

Pachifukwa ichi, ambiri amakono zipangizo zotetezera mafunde a mafakitale phatikizani chitetezo cha mphezi ndi kusinthana kwa mafunde mu gawo limodzi.

Kodi ma SPD a Mtundu 1+2 ndi Mtundu 2 amaikidwa kuti mu Power Systems?

Kuyika bwino kwa SPD kumatsimikiziridwa ndi Malo oteteza mphezi a LPZ lingaliro lomwe limagwiritsidwa ntchito mu uinjiniya woteteza ma surge.

Chigawo chilichonse chimayimira mulingo wosiyana wa mphezi.

Kukhazikitsa kwa SPD ya Mtundu 1+2

A Chipangizo choteteza kugwedezeka kwa mtundu wa 1 + 2 nthawi zambiri imayikidwa pa:
