〓The invention of the capacitor

.

Leiden University professor of physics Mason Brock (Musschenbrock 1692-1761 and German scientists Feng Kleist (von Kleist, 1700-1748), respectively, in 1745 and 1746 found a of capacitor with storage function, French priest and naturalist, electrical experts Nolet Nollet1700-1770 will this energy storage electric bottle called "Leyden jar. Many famous electrical experiments are using it can be carried out, such as the famous Franklin (B.Franklin 1706-1770) using the Leyden jar found positive and negative and the law of conservation of charge, 1752 July, Franklin from discharging experiment get inspired, the Philadelphia was shaking the World Kite cited lightning experiment, realize the unification of static and geoelectric. Later, people in foil or aluminum foil from both the inside and outside to wrap up the Leyden jar, the stored charge effect is more obvious, which began with the human use of the history of capacitor.

〓History of Capacitor Development

■ Leyden jar - the origin of the capacitor  bottle(1745)

Glass bottles as a medium, inside and outside the glass bottle made of tin foil electrode

■ Early Telegraph and telephone systems with low voltage capacitors (early twentieth Century)

Paraffin impregnated paper cotton fiber as the  medium, the electrode made of tin  foil

■ Early application of power capacitor in power system (1920-1950)

Mineral oil impregnated cotton fiber paper to make the medium, aluminum foil to make the electrode

■ Capacitor  impregnated with chlorination(1951-1975)

Chlorinated or impregnated wood fiber paper, or polypropylene film and paper composite medium

■ Development and application  of the new non toxic new impregnation agent(1975-1990)

PXE, BNC, C101, IPB and other new impregnation agents for the replacement of  chlorinatedchlorinated,Solid medium is a composite of membrane paper or the whole film medium

■ Modern power capacitor (1990-)

LEYSDEN uses the full film dielectric vacuum filling type capacitor, the metal thin film uses the zinc aluminum composite technology, the manufacture uses the corrugated and smooth cutting technology,in the vacuum environment, the electrolyte material and the injection of inert gas, advanced technology, advanced technology.

〓Based on professional services worldwide Leysden

■ LEYSDEN was founded in 1935 in Germany Grafing, east of Munich high-tech industrial park, BMW Motor Company, Siemens Electrical Industrial Park 30 km, is committed to the power transmission and distribution systems and industry users tuning filter compensation technology research.

■ LEYSDEN earliest products are mineral oil impregnated cotton fiber paper as a medium, aluminum foil as the electrode of the true sense of the capacitor in Bavaria began to apply, and in 1965 to establish a global support system, developed in 1991, modern capacitors, into the 21st century The rapid development of the world, in 2005 to enter China.

■ In response to LEYSDEN's booming business in East Asia, it has established a wholly-owned institution in Shanghai, China to co-ordinate Greater China and East Asia.
