500kV Series Porcelain-Housed Metal Oxide Surge Arresters Girmanin 500kV Tsari Porcelain-Housed Metal Oxide Surge Arresters

Bayanan 

500kV Series Porcelain-Housed Metal Oxide Surge Arresters na ita ce gwamnati da dama a wurin karamin zafi (UHV) da kuma jirgin zafi, musamman 500kV jirgin zafi, tashar zafi, da kuma abubuwa masu shiga (misali, transformers, circuit breakers). Yadda aka fada shi shine don kawo yawan overvoltages da suka faru saboda harsunan barazan, faɗaƙa, ko kuma nasara, bayyana yawan surge currents zuwa gida, baki daya da yawan voltage levels da ya fi sani a lokacin mulki. Suke fitowa a cikin porcelain housings na dama, sun yi kokarin inganci da metal oxide varistor (MOV) technology mai yawa, don tabbatar da ingancin defense don 500kV grid infrastructure da za su iya faru saboda electrical surges wanda za su iya haifar da abubuwan zafi ko kuma cut-off.

Faifai 

• Superior Surge Handling Capacity: An samun da multi-layer metal oxide varistors (MOVs) da high non-linear resistance characteristics. Sun zama da kyau don kawo yawan surge currents (zama da haka several hundred kA) daga harsunan barazan ko kuma faɗaƙa, kuma bayyana yawan overvoltages zuwa safe levels.

• Durable Porcelain Housing: Cikakken enclosure na porcelain na ita ce weather-resistant, corrosion-proof, da kuma mechanically strong, an samun da shi don kawo yawan environmental conditions (misali, high humidity, pollution, extreme temperatures, and seismic activity). Yana ba internal MOV components insulation da kuma physical protection.

• Low Leakage Current: Optimized MOV formulation ta koyar da leakage current during normal operation (typically <100&mu;A), kuma ta koyar da energy loss da thermal stress. Wannan ta tabbatar da long-term stability da kuma ta ci gaba tsari (up to 20+ years).

• Self-Recovery Performance: Bayan bayyana surge, an yi return arresters zuwa high-resistance state, kuma ta koyar da continuous current flow da kuma ta koyar da interference with normal grid operation. Wannan self-recovery capability ta koyar da need for manual resetting.

• Series Configuration Adaptability: An samun da shi don series connection don match 500kV voltage level, with uniform voltage distribution across units. Integrated grading rings or capacitors ta tabbatar da balanced electrical stress, enhancing overall system reliability.

• Easy Installation & Maintenance: Lightweight compared to traditional arresters, with standardized mounting flanges for compatibility with 500kV substation structures. Many models include built-in monitoring ports for leakage current or temperature checks, facilitating predictive maintenance.

• Compliance with International Standards: Meets IEC 60099-4, ANSI/IEEE C62.11, and other global standards for surge arresters, ensuring compatibility with 500kV grids worldwide and adherence to safety and performance requirements.
