Resistance cage
First, the use of
Without a sense resistor is mainly used to limit the current in the power system of RWG series line, reduce the voltage or adjust the system parameters, is widely used in AC filter and overvoltage damping absorption device or neutral grounding system, requirements of residual inductance in rare occasions.
Two, structure and its characteristics
Series type without a sense resistor with high resistance alloy wire, high temperature resistant, alkali free glass fiber with high strength as weft, with no sense of weaving woven. Each unit of resistance is made of high temperature insulation silicon varnish, so that all the resistance units are both rigid and flexible. The resistor body has the advantages of small volume, light weight, high insulation strength, good heat radiation effect, and greatly improves the reliability of the resistor.
Three, the use of conditions
1, system voltage: 6KV, 10KV, 35KV, 110KV, 220KV, 500KV;
2, frequency: 50~60Hz;
Altitude: 3, less than 1000 meters, if there are special requirements separately;
4, ambient temperature: -40 degrees C ~+40;
5, installation location: indoor / outdoor (selected by the use of units);
6, installation place: should be no corrosive gas, no conductive and explosive dust;
7, if there are special places to be ordered before ordering.
Four, the main technical parameters
1, system voltage: 6500KV;
2, rated frequency: 50~60Hz;
3, nominal resistance: 0.1 20K ohm;
4, manufacturing deviation: 0.5%, 5%, 10% (20 C under DC resistance);
5, temperature coefficient: no more than 8 * 10-5/;
6, long-term over current: 1.1ln;
7, insulation: GB311.1 high voltage power transmission equipment with "insulation".
