5-75 kVA/5-167 kVA Kompleta a tafi masu inganci na mutanen karamin jirgin magana mai zurfi

Na'antu：

Maimaita shi ne da Complete Self - Protection (CSP) na da nasara mai yawa. Suna taka zama da surge arresters masu primary da suka haɗa, MagneX arc - extinguishing chambers, ko circuit breakers masu secondary da voltage fuses masu primary da suke fito. Ba a buƙaci da muhimmancin daɗi wani abubuwa da ba a yi da shi, wanda ya taimakawa da tsari a kan karkashin sauri. Yawan kashi na wannan maimaita ta 5 - 75 kVA (kafin an haɓar da MagneX arc - extinguishing chambers, za ta iya zuwa 5 - 167 kVA), kuma zai iya samun standard electrical - grade mineral insulating oil ko FR3 liquid masu gida.

Tushen:

• An haɓar da over - current devices da surge arresters masu cikin, wanda ya taimakawa da hanyar daɗi wani abubuwa da ba a yi da shi.

• Protection da ke nuna fault da overload masu secondary zai iya samun ita da circuit breakers masu secondary da weak links ko MagneX arc - extinguishing chambers da za su zama optional.

• Nasara ta da kyau ko ta fi dace da standards masu industry, kamar ANSI, NEMA, da DOE energy - efficiency standards.

• An haɓar da core design masu interlaced da EPRI ya bayyana.

• Core da coils suna da cutar da take da shiga da field failure rates mai yawa, kuma akwai options da grain - oriented steel ko amorphous steel.

• Dome cover design da formed cover strip suna taimakawa da withstand voltage capabilities, suna da shi bushing overhang, kuma suna taimakawa da cover retention.

• High - voltage bushing design ya taimakawa da washer protection da sealing performance masu daidai.

• Za a iya haɓar da shi da koyar da Rural Utilities Service (RUS) specifications.
