2007-05-14――145PM63-B通过消除短线出错中断静电容降低变电站成本,简化设计。 宾夕法尼亚州Mt. Pleasant5月10日新闻――电力和自动化技术领域领袖厂商今天宣布推出新型145kV高压断路器。 145PM63-B高压断路器在40-, 50-, and 63-kA的121-145 kV产品应用中使用新型高性能断续器,静电容无需满足ANSI标准,该标准用于评定短线出错中断性能。断路器封装和整体尺寸与早期的145PM断路器设计是一样的,该断路器保留了HMB-2型弹簧储能液压操动机构技术的优点,这是HMB-1的一个功能更强大的下代产品。新型断路器的主要特性包括: • 通过消除要求短线出错中断功能的应用中的静电容降低工程造价,采集,安装和维护成本 • 简化SF6气体泄漏监测系统,消除潜在泄漏点 • 无需安装带断路器的电容器,降低总重量和基本成本 • 现场简单替换变压器,无需拆除套管,大大降低维护和维修成本 • 模块化的高性能断续器平台,允许整体组件现场简单替换,降低断续器维修时间至约1天或更少,工厂转换程序通过使用不需现场调整的预测组件可以进一步降低替换费用 • 带硅橡胶绝缘子的复合套管防污染,重量轻(可选用陶瓷套管) 所有特性都可以降低总成本,提高系统可靠性。新型145PM63-B设计可在145PM系列产品无法触及的领域中应用。 ABB(www.abb.com)是电力和自动化技术领域的全球领导厂商,致力于为工业和电力行业客户提供解决方案,以帮助客户提高业绩,同时降低对环境的不良影响。ABB集团的业务遍布全球100多个国家,拥有109,000名员工。 original text: [COLOR=#708090]ABB Introduces New High Voltage Circuit Breaker 2007-05-14 - The 145PM63-B simplifies substation cost and design by eliminating shunt capacitance for short line fault interrupting Mt. Pleasant, Pennsylvania, May 10, 2007 – ABB, the leader in power and automation technologies, announced today the release of a new 145kV high voltage circuit breaker. The 145PM63-B high voltage circuit breaker utilizes a new high performance interrupter to serve 121-145 kV applications at 40-, 50-, and 63-kA ratings without need for shunt capacitors to meet ANSI standards for short line fault interrupting performance. The breaker footprint and overall dimensions are identical to earlier 145PM designs. The breaker retains the advantages of spring-hydraulic drive technology with the HMB-2 operating mechanism, a more powerful version of the well-proven type HMB-1 unit used by its predecessor. Key features of the new breaker include: • Lower engineering, acquisition, installation, and maintenance costs by eliminating the need for shunt capacitors for applications where short line fault interrupting capability is required • Simplified SF6 gas system, eliminating potential leak points • Elimination of breaker-mounted capacitors, lowering total weight and reducing foundation costs • Easy replacement of current transformers in the field without removing the bushings, significantly reducing maintenance or modification expense • Modularized high-performance interrupter platform, enabling the one-piece units to be easily removed and replaced in the field during maintenance. This cuts maintenance cycle time on an interrupter to approximately 1 day or less. A factory exchange program can further reduce replacement expenses through use of pre-tested units which require no field adjustments. • Composite bushings with silicone rubber insulators that offer a pollution resistant, lighter-weight construction (porcelain bushings optionally available). All of these features lower total cost of ownership and improve system reliability. The new 145PM63-B design provides opportunities for installation in applications previously not served by 145PM offerings. ABB (www.abb.com) is a leader in power and automation technologies that enable utility and industry customers to improve their performance while lowering environmental impact. The ABB Group of companies operates in around 100 countries and employs about 109,000 people. [/COLOR]
