              塑殼斷路器作為與框架斷路器的應用對比

              來源:http://www.cekidots.com/ 日期:2021-12-28 發布人:admin

              塑殼斷路器采用的是塑料化結構,它的特點是斷路器外殼和框架都采用的是塑料壓制而成,并且它將觸頭、滅弧系統等都放在了一個絕緣小室中,以防止其之間發生短路,并為了確保電弧能夠向上噴出,保證了觸頭系統可靠分斷。而框架斷路器采用的則是模塊化結構,它分為框架、觸頭滅弧系統、手動操作機構、電動操作機構、智能型控制器以及抽屜座等結構。并且其每個部分均可成為一個完整獨立的部件,組裝時只需1-2個螺釘即可將其固定,拆裝也十分方便,便于其檢修維護。

              The molded case circuit breaker adopts a plastic structure, which is characterized in that the shell and frame of the circuit breaker are made of plastic, and the contact and arc extinguishing system are placed in an insulating chamber to prevent short circuit between them. In order to ensure that the arc can be ejected upward and ensure the reliable breaking of the contact system. The frame circuit breaker adopts modular structure, which is divided into frame, contact arc extinguishing system, manual operating mechanism, electric operating mechanism, intelligent controller and drawer seat. And each part can become a complete and independent part. It can be fixed with only 1-2 screws during assembly. It is also very convenient for disassembly and assembly, which is convenient for its maintenance.
              塑殼斷路器的產品種類繁多,其特點是結構緊湊,操作容易,其結構與功能也比較簡單。而框架斷路器則功能完善,特別是近年來的單片機技術的廣泛應用,從而使框架斷路器逐步朝著高性能、易維護、網絡化的方向發展。
              Molded case circuit breakers have a wide variety of products, which are characterized by compact structure, easy operation, and simple structure and function. The frame circuit breaker has perfect functions, especially the wide application of single chip microcomputer technology in recent years, which makes the frame circuit breaker gradually develop in the direction of high performance, easy maintenance and networking.
              在額定電流上,塑殼斷路器一般為630A以下,而框架斷路器的額定電流要大很多,一般為630A-6300A。
              In terms of rated current, the rated current of molded case circuit breaker is generally below 630A, while the rated current of frame circuit breaker is much larger, generally 630a-6300a.

              而在分段能力上,框架斷路器要比塑殼斷路器高。 一般情況下,800A以上的回路或分段能力要求比較高的回路大多采用的是框架斷路器,而630A以下的回路,則一般使用塑殼斷路器。
              In terms of sectioning capacity, the frame circuit breaker is higher than the molded case circuit breaker. Generally, frame circuit breakers are mostly used for circuits above 800A or circuits with high sectioning capacity requirements, while molded case circuit breakers are generally used for circuits below 630A.
              框架斷路器的所有零件都裝在一個絕緣的金屬框架內,常為開啟式,可裝設多種附件,其更換觸頭和部件也較為方便,多用在電源端總開關。而 塑殼斷路器的接地線端子外觸頭、滅弧室、脫扣器和操作機構等都被裝在了一個塑料外殼內,一般情況下我們不考慮其維修,它比較適用于作支路的保護開關,其大部分采用的是手動操作。
              All parts of the frame circuit breaker are installed in an insulated metal frame, which is usually open, and can be equipped with a variety of accessories. It is also convenient to replace contacts and components, which are mostly used in the main switch at the power end. The outer contact of the grounding wire terminal, arc extinguishing chamber, release and operating mechanism of the molded case circuit breaker are installed in a plastic shell. Generally, we do not consider its maintenance. It is more suitable for the protection switch of the branch, and most of it adopts manual operation.
