Unsa ang mga key points para sa selection sa outdoor vacuum reclosers?
System Parameter Matching: Choose a recloser that matches the rated voltage, rated current, and short-circuit current levels of the power system. Ensure that the rated voltage of the recloser is equal to or higher than the system voltage, the rated current meets the requirements of the line load current, and the rated short-circuit breaking and making currents are greater than the maximum possible short-circuit current in the system.
Reclosing Performance Requirements: Consider the specific requirements of the power system for the reclosing function, such as the number of reclosures, reclosing time intervals, and reclosing success rate. Based on different application scenarios and power supply reliability requirements, select a recloser with appropriate reclosing performance. For example, for critical power supply lines, a recloser with a higher number of reclosures and flexible reclosing time intervals may be required.
Type of Operating Mechanism: Choose an appropriate operating mechanism based on actual needs. Spring-operated mechanisms are suitable for outdoor environments where high reliability is required and maintenance conditions are relatively poor. Permanent magnet-operated mechanisms are better suited for applications requiring high action speed and frequent operations.
Environmental Adaptability: Given the harsh conditions of outdoor environments, consider the environmental adaptability of the recloser. This includes weather resistance, pollution resistance, and water and dustproof performance. Selecting a recloser with good environmental adaptability ensures stable performance during long-term outdoor operation.
Brand and Quality: Choose well-known brands and high-quality recloser products. These products have strict quality control systems in design, manufacturing, and testing, ensuring the performance and reliability of the product. Additionally, good after-sales service is an important factor to consider when choosing a brand, as it ensures timely resolution of issues that may arise during equipment operation.
1. Katungdanan pagprotekta sa kalibutan nga teknolohiya sa gas nga gipangmihun sa insulation
CO ₂ ug perfluoroketone/nitrile mixture gases: sama ni CO ₂/C ₅ - PFK (perfluoroketone) o CO ₂/C ₄ - PFN (perfluoronitrile) mixture gases. Ang mga mixed gases mao ang nagpadugay sa arc extinguishing ability sa CO ₂ ug ang mataas na dielectric strength sa perfluorinated ketones/nitriles, nagsilbi kini isip substitute alang sa SF ₆ sa high-voltage applications. Tumong, ang CO ₂/C ₄ - PFN mixed gas adunay kauban nga commercial application sa high-voltage circuit breakers, uban sa insulation ug breaking performance nga dako pa sa SF ₆, ug naka-reduce ang global warming potential (GWP).
Hangin ug perfluoroketone mixed gas: Sa medium pressure applications, ang mixture sa hangin ug C ₅ - PFK mahimong gamiton isip insulation medium. Pinaagi sa pag-optimize sa mixing ratio ug presyon, maabot ang insulation performance nga makatulad sa SF ₆ samtang nakakurta sa environmental impact.
2. Teknolohiya sa vacuum circuit breaker
Vacuum arc extinguishing chamber: Nagamit ang mataas na insulation strength ug fast arc extinguishing ability sa vacuum environment, nahimong substitute sa arc extinguishing function sa SF ₆. Ang vacuum circuit breakers gigamit sa medium ug low voltage fields, lalo na sa scenarios nga may high environmental requirements. Ang ilang mga advantage mao ang walay greenhouse gas emissions ug excellent arc extinguishing performance, apan kinahanglan maghatag og solusyon sa mga problema sama sa vacuum sealing ug contact materials.
Pagsulbar sa vacuum circuit breaker ug gas insulation: Sa uban nga medium voltage switchgear, ang vacuum circuit breakers gigamit isip breaking elements, gisulbar sa dry air o nitrogen isip insulation media, aron mobalhin og katungdanan pagprotekta sa kalibutan nga gas insulated switchgear (GIS) nga balansehan sa insulation ug arc extinguishing performance.
