An overview of the
LA - 10 q type current transformer is suitable for rated frequency 50 hz, rated voltage 10 kv and below the indoor unit in the power system for electric current, electric energy measurement and relay protection
Types of meaning
Introduction of the structure
Transformer is epoxy resin casting. Can be used in damp and high temperature, product surface condensation and tropical regions; 200 a and below for the structure of semi-closed, 200-1000 - a single-turn type fully enclosed casting structure.
Technical parameters
1. The rated insulation level of 75 kv / 12/42 (surface condensation and artificial class II filthy conditions)
2. The rated primary current, accurate and the corresponding rated output, rated short-time thermal currents are shown in table 1
3. The load power factor: COS Φ = 0.8 (lag)
4. The rated secondary current, 5 a
5. Partial discharge level accord with GB7354-87 and IEC185 transformer partial discharge measurement, the apparent power is not more than 20 PC
6.10 P level limit coefficient and secondary load curve accurately see the appended drawings
