FD95 Single-phase watt-hour meter(socket connection) Brief Introduction 　　 Type FD95 single-phase watt-hour meter(socket connection)is known as Round Enclosure Mete and is the single-phase long-life inductive watt-hour meter which is specially designed for European and American user for measuring with rated frequency 50 or 60Hz single-phase two-wire a.c.active electric energy. 　　This product is securely fixed indoor and apply with the temperature conditions such as ?100C~+500C,relative humidity not more than 85%(current temperature is 250C),and no erode gas and protect from dust,salt fog and dew.The main performance comply with Chinese national standard GB/T15283-1994 and International Electro-technical Commission standard IEC521-1988,US standard ANSI C12.10-1978. 　　This product provides not only the good performance of FD series,but also the common dimension and connection of European and American user so it is very popular in the overseas market. Construction and Feature 　　 Type FD95 single-phase watt-hour meter(socket connection)is produced with the main components of FD95 and many years experiments of long-life watt-hour meter which comply with the requirements of European and American user. This product boasts with round construction and glass cover,phenolic resin base and socket connective terminal with the feature of easy use. 　　The electromagnetic components of the meter are in prone position.The separate voltage core is riveted by voltage stamping sheet.The damping magnet is die-casted directly on the frame,current coil is wound without skeleton.The rotator components adopt magnetic bearing.Therefore,it has the features of large load current(Imax=200A),high overload(6.67 times),long-life serice(over 25 years),low power loss(less than 1 W)etc. 　　Base:It adopts phenloic resin with sturdy and reliability stable performance and good insulation. 　　Frame:AI-Ni-Co magnetic damping is die-casted on aluminum silicon alloy frame with steady structure. 　　Electromagnetic elements:The iron core adopts high silicon steel sheet by riveting with special heat treatment that has the feature of low power loss and stable performance. 　　Rotator component(bearing):Aluminum disc can run steadily,especially good performance in terms of starting and creeping.The non-abrasion magnetic bearing needs to be oiled and maintained. 　　Nameplate:It adopts special technique treatment in aluminum sheet with its feature of anti-sun light. 　　Register:With the compposing of metal and plastic,the mesh state of gear is very good.Therefore,it has the feature of lower friction coefficent and stable running for five drum digits of the register with clear display. 　　Glass cover:With high transparent cover and closed rubber washer,the sealing performance is quite very good..
