An overview of theLAJ-10Q Current Transformer
LAJ-10Q Current Transformer is suitable for rated frequency 50 hz or 60 hz, rated voltage level for 10 kv and below indoor device 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. For under 300 a and semi-closed structure, 400-800 - a single-turn type fully enclosed casting structure, strengthen the products dielectric strength, industrial and mining products
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 also do (1 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
