ABB中間繼電器/條形熔斷器隔離開關的技術特點主要有單斷點和雙斷點，

The technical features of ABB intermediate relay / strip fuse disconnector mainly include single breakpoint and double breakpoint,

條形熔斷器隔離開關它不光具有開關、保護功能，通過系統中其他可選功能部件 可以擴展其功能，使其具有更大的靈活性，可以說它不單純是一種開關形式，更重要的是他 是一套完整的智能化系統。 采用插接式技術的電纜分支回路用配電屏，如與抽出式技術相比較，它顯得更經濟。它的結構緊湊，并通過進線側的插接觸頭，能實現快速改裝或 所有開關都可配電子式熔絲監視裝置， 它可對 3 個熔斷器進行電子式熔斷監控， 可通過 單獨安裝的故障指示器實現向控制室供電以及向控制室傳輸信號。根據報警指示器的設計, 可將多達 10 個或多達 100 個的隔離開關串聯,由此使"+"線,,"-"和信號線均相連。 這三根線 最終與故障指示器相連，至控制室的故障信號(多個信號)經由信號線被傳輸。

Strip fuse disconnector not only has switching and protection functions, but also can expand its functions and make it more flexible through other optional functional components in the system. It can be said that it is not only a form of switch, but also a complete intelligent system. It is more economical to use the branch circuit technology, such as the plug-in power distribution screen. It has a compact structure, and can realize rapid modification through the plug-in contact on the incoming line side, or all switches can be equipped with electronic fuse monitoring device. It can carry out electronic fuse monitoring on three fuses, and can supply power to the control room and transmit signals to the control room through separately installed fault indicators. According to the design of the alarm indicator, up to 10 or up to 100 disconnectors can be connected in series, so that the "+" line, "-" and signal line are connected. These three lines are finally connected with the fault indicator, and the fault signal (multiple signals) to the control room is transmitted through the signal line.

由于熔斷器保護有許多的優勢，在歐洲一直得到廣泛的應用，特別是在低壓 電網中的電纜和線路保護這些應用領域。因此各類條形隔離開關成功地應用了不斷發展的開關技術與熔斷器結合，因其具有體積小、安全性高、價格適中等優點，有理由相信，3NJ 系列條形隔離開關一定會在諸 如電網改造等更廣泛的領域中發揮更大的作用。隨著近些年農網改造的深入，對于此類產品的需求也會大大加大，同時對于安全燈多方面，也是十分有必要的。

Because fuse protection has many advantages, it has been widely used in Europe, especially in the application fields of cable and line protection in low-voltage power grid. Therefore, all kinds of strip disconnectors have successfully applied the combination of constantly developing switch technology and fuse. Because of its advantages of small volume, high safety and moderate price, it is reasonable to believe that 3nj series strip disconnectors will play a greater role in a wider range of fields such as power grid transformation. With the deepening of rural power network transformation in recent years, the demand for such products will also be greatly increased. At the same time, it is also very necessary for many aspects of safety lamps.

制作電容器常見材料：一般來說，低壓電容器的原材料決定了其性能的表現和制造成本及銷售價格，所以本文將詳細討論下目前市面上常見的電容器產品的原料選擇情況，對于電容器能有更好的了解。

Common materials for making capacitors: Generally speaking, the raw materials of low-voltage capacitors determine their performance, manufacturing cost and sales price. Therefore, this paper will discuss in detail the selection of raw materials of common capacitor products in the market, so as to have a better understanding of capacitors.

材料一:固體電介質

Material 1: solid dielectric

一般電力電容器的固體介質為電容器紙，隨著電容器產業的不斷發展，塑料薄膜也被引入電容器的生產制造中，而且在最近幾年薄膜介質的電力電容器已經漸漸成為電容器市場上的主流產產品。它們的性能各有優點。電容器紙e較大及浸漬性能好，所以一直被電容器采用，而塑料薄膜的技術越來越成熟,其優點也正在顯示出來。

Generally, the solid medium of power capacitors is capacitor paper. With the continuous development of capacitor industry, plastic film has also been introduced into the production and manufacturing of capacitors. In recent years, power capacitors with thin film dielectric have gradually become the mainstream products in the capacitor market. Their performance has its own advantages. Capacitor paper e is large and has good impregnation performance, so it has been adopted by capacitors. The technology of plastic film is becoming more and more mature, and its advantages are also showing.

由于紙和膜各有其特點.現在有的用紙、膜復合介質來制作電力電容器的材料也是市面上比較常見的一種做法.。

Because paper and film have their own characteristics At present, some materials for making power capacitors with paper and film composite media are also a common practice in the market.

材料二:液體電介質

Material 2: liquid dielectric

液體介質在電力電容器材料中用作浸漬劑.以填充固體介質中的空隙，從而提高介質的介電常數和耐電強度.改善局部放電特性和散熱條件等。 這幾年電容器材料中選擇十二烷基苯、二芳荃乙烷((S油)的產品也被廣泛應用。而蓖麻抽因e大，在脈沖電容器中得到了應用。三氯聯苯電氣性能較 穩定.但由于它具有毒性而被淘汰. 。

Liquid medium is used as impregnant in power capacitor materials To fill the voids in the solid medium, so as to improve the dielectric constant and electrical strength of the medium Improve partial discharge characteristics and heat dissipation conditions. In recent years, Dodecylbenzene and Diarylethane (s oil) are also widely used as capacitor materials. The e-pump capacitor has been applied in large pulse. The electrical performance of Trichlorobenzene is relatively stable But it was eliminated because of its toxicity.

材料三:電極材科

Material 3: electrode material department

大部分的電極材料都是鋁箔，在并聯低壓電容器中，也 有用金屬化的方式作為電極 。這個沒有什么好講的,因為性價比的關系,現在鋁箔已經被大量并且廣泛運用在電力電容器的生產材料中.

Most of the electrode materials are aluminum foil. In parallel low-voltage capacitors, metallization is also used as the electrode. There is nothing to say about this. Because of the cost performance, aluminum foil has been widely used in the production of power capacitors
