This series of metering boxes are improved on the basis of similar products. They are suitable for electric energy measurement in outdoor AC power systems with rated frequency of 50Hz, rated voltage of 10kV and 6kV. It is an ideal substitute for old-fashioned oil-immersed products. This series of products is composed of two parts: voltage and current combined transformer and measuring instrument box. The transformer is equipped with two independent voltage and current transformers, which are divided into phases A and C. The outer wall of the combined transformer is equipped with power and reactive watt-hour meters, as well as a joint junction box for testing, and the meter box is used during operation. Covered to prevent electricity theft. The inner core of JLSZV2-6、10W products is made of epoxy resin casting. The outer shell is made of steel barrels to avoid direct sunlight damage to the epoxy resin casting body caused by ultraviolet rays. This type of transformer is designed into the such structure: epoxy-resin casting. fully sealed and post type. Due to employing the outdoor epoxy-resin casting,the product is featured with long service life, withstanding the electric arc, ultraviolet ray and aging. etc. This product is combined by two single-phase full-insulation voltage transformers that are formed into "V"-shaped connection and two current transformers that are connected to phases A and C in series.And, the current transformer secondary winding that are equipped with the taps can get the different current ratios. The secondary outlet terminal has a connection guard, this guard has an outlet hole at the bottom, so, it is very convenient to connect the wires,and it is very safe and reliable,realizing the electricity larceny prevention.In addition,the channel of base has four installation holes that are helpful for mounting.dry type electric measuring tank/ 6, 10 kV voltage transformer/ voltage transformer Applicable scope: 1. Electric energy metering of high-voltage transmission lines of village drainage, irrigation and pumping stations, township enterprises, processing plants, small and medium-sized factories, mines, transportation and other enterprises and institutions, as well as temporary power stations in forestry and construction sites. 2. The measurement of the power generation of small power stations or the measurement when the power grid of the small power station and the country are connected to each other when they transmit electric energy
