Switchgear Simplified Design | Yan Aiki da Turanci da Amfani da Ba Da Yawancin Karkashin Lalle

Tattalin daidaita yana nufin kayayyakin kadan. Idan a bayar da hukuma cewa daidaita na gaban daidaike yana nuna hasken kayayyakin kadan, saboda haka kayayyaki kadan ke taimakawa wajen samun daidaita masu kyau.

Don PT trolleys a air-insulated switchgear, an yi amfani da takarda mai sauƙi mai kadan. A tsakiyar kabel, PT trolley ya ɗaukar da zama a kan chassis 200mm don rikicin sama uku da bambanta. Amma, ana amfani da PT’s built-in fuse da striker mechanism, wanda ke taimakawa a bincike mai kyau da busbar. Fasahar plug ya danganta kusan, wanda ke taimakawa ingancin daidaike da kisan abin daidaike—kadan, daidai, daidai, da kuma zama a inganta. Don intelligent switchgear, intelligence ba mafi kyau a bukata ta shaida shaida ba.

Akwai kyau a hardware mai kadan, amfani da software don measurements da protection calculations. Tsakiyar ita ce protection functionality, wanda yana bukatar zuwa. Yana bukata a bincike gwamnati daidaike daga nau'ukan gwamnati—masu short circuits, ground faults, overvoltage, undervoltage—da kuma sarrafa commands kafin juyin gwamnati don ingancin daidaike. Na biyu shine monitoring da power quality. Ba a tabbatar da safe da kontrollabe power, kuma yanayin kuɗi—timely compensation of reactive power da wasu parameters, automatic switching, da kuma fine-grained control don taimakawa efficient energy use.

Monitoring da health da equipment yana nuna in yake daidaike. Tsarin da health monitoring yana nuna in yake ya faruwa daidaike. Continuous monitoring taimakawa equipment ya ɗauki a cikin daidaike, wanda ke taimakawa early intervention da kuma kuɗi daga periodic, reactive maintenance zuwa proactive, targeted repairs.

Yadda ake yi online temperature monitoring? Akwai dalilai da suka fiya—design, installation, da management. Tsakiyar da ya fi yin daidaike shine vacuum circuit breaker trolley contacts. Saboda circuit breaker da switchgear suna da kayayyakin kadan, yawancin primary contacts zai iya faruwar daidaike, wanda ke taimakawa poor contact da kuma excessive heating. Muna iya amfani da fixed-mounted circuit breakers da disconnectors? Disconnectors suna da fixed relative positions of moving and stationary contacts within the same body, wanda ke taimakawa ingancin daidaike.

Fixed-mounted circuit breakers suna da kyau idan breaker itself yana da daidaike masu kyau, maintenance-free, da kuma babu need for servicing within its service life, wanda ke taimakawa overall system reliability. Duk waɗannan functions suna neman sensors da measuring devices, wadannan suna da kyau a yi installation karkashin equipment functionality. An yi amfani da smart components ba zai iya ƙara daidaike da equipment.

Gas-insulated switchgear tana iya haɗa da multiple functions. Wannan da sealing technology da manufacturing suna ƙara, wanda ke taimakawa single gas compartment ya ƙara da multiple bushings for metering PTs, supply PTs, da kuma cable in/out connections. Removable designs tana ƙara da individual components za a ƙara game da maintenance, amma wannan ana iya ƙara da kompromis saboda insufficient product quality. Idan product quality ya ƙara da ma'adi da service life ya ƙara da expectations, integrated designs suna da kyau.

Ba a maimaita a fuskantar 40 shekara; idan a yi 10 shekara free maintenance operation, wanda ke taimakawa ƙaramin kyau. Kamar yadda maintenance personnel sun ce, idan mechanical life of circuit breakers suna ce 10,000 operations, amma a tunanen suna ƙara da 3,000. Ya ƙara da a lura da intelligent health monitoring devices, yana da kyau a lura da improving product quality don genuinely extend lifespan da kuma enhance reliability.

Outdoor switchgear yana bukatar design don direct outdoor use—kadan da daidai. Babu da kyau a ƙara indoor switchgear inside a separate outdoor enclosure, ba zai iya ƙara outdoor switchgear. Don outdoor installations without the need for an operating corridor, switchgear’s side panels zai iya ƙara directly as the outdoor enclosure, wanda ke taimakawa reduce cost, weight, da kuma footprint. The new power system demands local integration, consumption, da isolation of green, clean energy, wanda ke taimakawa flexible da kuma simple distribution equipment. Self-powered, maintenance-free systems with distribution automation, remote control, measurement, regulation, da signaling suna nuna in yake convenience, flexibility, da minimal special design.

Control and protection methods should match the application: where a load switch-fuse combination suffices, a circuit breaker is unnecessary.
