2. Introduction to the structure
LMZW-0.5, LMZJ1-0.5W current transformer is a fully enclosed structure of ABS flame-retardant plastic shell, which makes the product less susceptible to moisture; the magnetic material adopts annealed ring iron core to ensure the accuracy of the product 0.2 or 0.5; superconductivity The application of magnetic materials enables the product to reach 0.2S or 0.5S level under the same volume, so that the product can accurately measure electric energy under a wide load of 1%-120% of the primary current. The first time is: P1, P2, and the second time is S1, S2 When the primary current flows from P1 to P2, the secondary current flows from S1 to S2 through the external loop, which is degradability.
Special reminder: When the primary current passes through, the secondary circuit must not be open, otherwise high voltage will be generated.
3. Conditions of use
1 The altitude does not exceed 1000 meters;
2 The ambient temperature is not higher than +40 degrees, not less than -5 degrees
3 The relative humidity of the surrounding air is not more than 85% (20 degrees Celsius);
4 There is no gas, vapor, chemical deposition, pollution or other explosive and corrosive media that seriously affect the insulation of the transformer in the installation site.
Special reminder: When the primary current passes through, the secondary circuit must not be open, otherwise high voltage will be generated.
Fourth, the main technical parameters:
1 Rated primary current: 100-1200A
2 Rated secondary current: 5A or 1A
3 Rated voltage: 0.66KV
4 Measurement accuracy level: 0.2S, 0.5S, 0.2, 0.5
5 The power factor of the load: COS∮=0.8 (lagging)
6 Product standard: GB1208-2006 <current transformer>;
