芬蘭的交流驅動器生產商偉肯將在挪威奧斯陸于6月12日到15日舉行的2007 NorShipping展覽會上展出其世界上范圍最寬的低壓液冷交流驅動器。偉肯DriveSynch，一款全新的應用冗余觀念的平行高壓NXP驅動器將第一次面市。 　　偉肯的低壓，高功率液冷交流驅動器是應船舶和離岸行業(yè)簡單適用性要求而專門設計的。此類型的批準證書已經由Bureau Veritas and Det Norske Veritas發(fā)行，批準認證步驟是在其它幾個認證機械完成的。 　　偉肯執(zhí)行副總裁Heikki Hiltunen先生說：“我們模塊化技術平臺可使我們的液冷低壓交流驅動器的功率達到兆瓦。我們在船舶和離岸業(yè)務擁有系統(tǒng)的合作伙伴，對于他們而言液冷驅動器是較好的選擇，原因有許多，如他們的利益空間，無噪音操作，低損耗，熱負荷低等。” 　　偉肯液冷交流驅動器的功率范圍在7.5KW到5MW之間，電壓范圍380-500V和525-690V。這些產品可由一個三相或六相整流器或是一個主動前端整流器來完成。偉肯NXP就是利用的此平臺和基于偉肯DriveSynch技術控制觀念的產品。 　　偉肯AS常務董事Mr Per Halvor Rønningen說：“偉肯是系統(tǒng)整合者的理想合作伙伴。我們擁有市場上系列最多的產品，擁有偉肯DriveSynch技術，我們可以創(chuàng)新冗余驅動系統(tǒng)并提高系統(tǒng)的安全性和實用性。我們獨立的市場地位與我們全球化服務網絡和網絡支持是分不開的?！? 　　偉肯的AC驅動器已可以交付控制使用，如主要的推進器，操舵裝置如絞車，輪盤和各種各樣的絞盤。交付還包括相當數量的用于挖泥，制冷，貨物裝卸和油鉆用于控制閥門的交流驅動器。 original text [COLOR=#708090]Vacon exhibits the widest range of liquid-cooled AC drives at NorShipping The Finland-based AC drives manufacturer Vacon will show the world‘s widest range of low-voltage liquid-cooled AC drives at the NorShipping Exhibition 2007 in Oslo, Norway on June 12-15. Also Vacon DriveSynch, a new fully redundant control concept for parallelling high-power Vacon NXP drives, will be introduced for the first time. Vacon‘s low-voltage, high-power liquid-cooled AC drives are specifically designed and easily adaptable for the needs of the marine and offshore industries. Type approval certificates have been issued by Bureau Veritas and Det Norske Veritas, and approval procedures are underway also with several other certification bodies. “Our modularized technology platform allows us to provide liquid-cooled low-voltage AC drives up to several megawatts. We have several system integrator partners in the marine and offshore business to whom our liquid-cooled drives are a preferred choice for various reasons, such as their space-saving benefits, silent operation and a low level of heat load, emission and harmonics,” says Mr Heikki Hiltunen, Executive Vice President, Vacon. Vacon offers liquid-cooled AC drives in the power range of 7.5 kW – 5 MW and in voltage ranges of 380 – 500 V and 525 – 690 V. These products can be supplied by a three- or six-phase rectifier or by an active front-end rectifier. The Vacon NXP is used as the control platform, and the control concept is based on the Vacon DriveSynch technology, which allows the control of one motor by means of 2 to 4 power units of 100 – 2,500 kW, thus bringing significant redundancy in the processes controlled by AC drives. “Vacon is an ideal partner for system integrators. We have the widest product range available in the market, and with our Vacon DriveSynch technology we can create redundant drive system and thus significantly improve system safety and availability. Our independent position, together with a global service network and support, are major benefits for system integrators,” says Mr Per Halvor Rønningen, Managing Director, Vacon AS. Vacon has delivered AC drives to control e.g. main propulsion, thrusters, steering gear as well as drawworks, topdrives, rotary tables and various types of winches. Deliveries also include a considerable number of AC drives to control pumps used in dredging, cooling, cargo handling and oil drilling. [/COLOR]
