JLSZV-6,10KV Dry Type Electric Measuring Voltage Transformer

Summary

This voltage and current combined transformer is suitable for voltage.current and energy measurement and relaying protection at the three-phase circuit of AC 50Hz and rated voltage 10kV, it is not only applied to the rural outdoor transformer substations, but also the small-sized industrial transformer substations and distribution substations, This product can fully take the place of JLSJW-10 type oil-immersed combined transformer.

Stucture 

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.

Technical parameter

1.Rated insulation level: 12/42/75kV.

2.The surface creepage distance meets the requirements of Ⅱ-class pollution.

3.This type of combined transformer has three phases that are combined by the single-phase voltage transformer and single-phase current transformer, here into, the voltage transformer adopts V/V-12 connection.

4.This type of combined transformer reaches such standards as GB20840.2-2014 Current Transformer, GB20840,3-2013 Voltage Transformer and GB17201-2007 Combined Transformer.

5.The rated transformation ratio of voltage transformer is 10000/100.and the rated secondary output of three phases is class 0.220VA.

6.The load power fact or COS is equal to0.8(lag),and the instrument security factor of current transformer FS is equal to 10or less than.

7.Environment temperature among 30℃-40℃,every days average temperatare shaHot exceed 30℃.

8.Altitude: < 1000m.  10KV  Electric Transformer/ electric measuring tamk/ electric Measuring Transformer
