6/10kV Tsohon kashi na biyu a kan tsohon kashi na uku da IEE-Business

Bayanan

A cikin hanyar daɗiyya da na iya a tashin jerin kasa mai sauƙi, wanda aka fayyace da 6/10kV uku na dry-type grounding transformer ya haɗa da aiki a ƙarin da suka fito. An yi aiki a tsari da epoxy resin vacuum casting thin-insulation technology. Duk da high da low-voltage windings an yi aiki da copper foils, wadannan suna da muhimmanci da zai iya haɗa kan 10pC. Saboda tsarin foil winding, yana da capacitance mai yawa da initial voltage distribution mai yadda, wanda ke tabbatar da kyau ga lightning impulse withstand capability. Windings suna da reactance heights masu yawa da ampere-turns masu yawa, tare da axial short-circuit force mai yawa, wanda ke tabbatar da kyau ga short-circuit resistance.

Daga F/H insulation classes, ana iya amfani da wannan transformer a ƙarin da suka fito a 155℃/180℃. Core na biyu ya haɗa da mineral oxide-insulated cold-rolled silicon steel sheets, wanda ke tabbatar da no-load loss da noise mai yawa. Yana da yawan jiragen ruwa, flame-retardant, da self-extinguishing, wanda yana da muhimmanci a urban distribution networks, industrial facilities, kamar haka. Ana iya amfani da shi zuwa 10,000kVA, wanda ke bayyana stable neutral grounding system don ≤35kV systems.

Muhimmiyar Tushen

•  Kyau ga Lightning Impulse Withstand Capability: Saboda high da low-voltage windings duka an yi aiki da copper strips (foils), interlayer voltage ya fi yawa, capacitance ya fi yawa, da initial voltage distribution na foil winding ya fi yadda. Saboda haka, yana da kyau ga lightning impulse withstand capability.

•  Kyau ga Short-Circuit Withstand Capability: Saboda reactance heights na high da low-voltage windings suna da yawa, ba a kasance helix angle, da ampere-turn balance between the coils ya samu. Axial force na high da low-voltage windings da short-circuit ya sa ta yawa. Saboda haka, yana da kyau ga short-circuit withstand capability.

• Kyau ga Anti-Cracking Performance: Dry-type transformer ya haɗa da epoxy resin "thin insulation (1-3mm) technology", wanda ya tabbatar da abubuwan lokacin da suka fito da ƙarin, ƙarfi, da yawan ƙarin lokaci, da ya tabbatar da anti-cracking requirements ba a gama. Yana da damar da problem na cracking da ba a iya canza ita da "thick insulation (6mm) technology", wanda ya bayyana reliable technical guarantee don dry-type transformers.

• Kyau ga Overload Capacity: Idan load losses na transformers da take da yawa suka duba, area na copper foil zai zama mai yawa musamman da copper conductor. Bayan samun volume, dosage na filling resin zai zama mai yawa. Saboda haka, heat capacity na winding ya fi yawa, da ya haɗa da short-term overload capacity na transformer mai yawa.

• Kyau ga Flame-Retardant Performance: Epoxy resin vacuum casting process ya haɗa da aiki ba a gama environmental pollution, wanda ya tabbatar da environmental protection. Transformer na da muhimmanci da maintenance-free, moisture-proof, resistance to damp-heat, flame-retardant, da self-extinguishing, wanda ya haɗa da aiki a duk abubuwa da lokutan da suka fito.

• Low Loss and Low Noise: Iron core na biyu ya haɗa da high-quality cold-rolled silicon steel sheets insulated da mineral oxides. Tun daga advanced processing technology, loss level da no-load current suka duba zuwa minimum, da ya samu very low noise level. Amma, assembled iron core ya haɗa da surface coated with class F resin paint don prevent dust, corrosion, smoke, da rust.

•  High Temperature Resistance Grade: Epoxy resin dry-type transformer na cikin F or H insulation, wanda ya iya amfani da ita a ƙarin da suka fito a 155℃ ko 180℃. Da take da yawa, yana da volume mai yawa da weight mai yawa, wanda ya haɗa da saving installation costs, kamar haka.

•  Relevant Technical Specifications: Capacity ≤ 10000kVA; Voltage ≤ 35kV;  Insulation grade: class F or H
