Standard Combined Transformer&Potential Transformer

1,Potential Transformer

  (1)Below 35KV potential transformer technical parameter:

     voltageratio:10/0.1kv ,10/0.1/0.1kv etc.

     accuracy class:0.2/0.5,0.2 ,6p,0.2/0.5/6p and so on

     rated load:15/15VA,15/20VA,15/15/30VA,40/40/100VA

  (2)The characteristics of below 35kv potential transformer:

  35KV potetial transformer adopts the vacuum epoxy resin vesting mold ,the pillar type fully enclosed structure,applying to the electricity system which rated [ower is 60 hz indoor or outdoor to protect the current ,electricity ,measurement and relay ,indoor potential transformer is suitable for all kinds of high voltage switch cabinet.

 Because the transformer adopts the fully enclosed casting mold insulation ,it do not need the special maintence ,exxcept get rid of the blemish surface regularly .It has small size ,very light and easy to fix.

2,Combined Transformers 

(1)35KVand below of the combined transformer technical parameters:

 voltage ratio:10/0.1KV,rated load:20VA

 current ratio:5-600/5A accuracy calss :0.2s rated loaad: 10 or 15 VA

(2)The characteristics of the 35KV and below of the combined transformers technical parameters :

 35 KV combined transformer adopts epoxy resin vacuun casting ,consists of two components   

(V/V two voltage transformer connection and two current transformer ),three components(Y/Y connection and voltage transformer is three current transformer ) portfolio as a whole ,apply to the rated frequency 50hz ,rated voltage 35KV and below with a three-phase power system of three phase or three pahse four wire table for electric energy metering with creepage is greater than distance ,overload ability ,good insulation properties ,high measurement accuracy ,preventing electricity-stolen ,etc.
