ASC Introduce
In power system of 6-66KV, when capacitive current associated with single-phase ground fault excess 10A (It is 30A in 6-10KV cable circuit system), arc-supression coil device should be adopted to prevent damages. The device is designed based on eletrical standard of DL/T620-1997 (standard of overvoltage protection and insulation co-ordination of AC electrical equipments)
SPECIFICATIONS (Order Note)
1.Abient Temp. of operation is between -20 centigrade and +40 centigrade
2.Relative humidity of Air is or less than 80%(+20 centigrade)
3.Altitude does not excess 2000m(If excess, pls indicate in order)
4.There is no corrosive gas around the site, so is conductive dust
6.There is no severe shocked movement around the site.
Structure
1.MRD-XHZ micro-computer controller and PK screen.
2.Grounding Transformer
3.Regulated load arc supression coil
4.MRD damping resistor cabinet as well current/voltage transformer.
Technology Quality
with IEEE-32. Routine tests performed on each Neutral Grounding Resistor are measurement of resistance, high voltage power frequency, insulation measurement, aspect verification, dimensional control. Mingrui’s internal quality system has been developed and certified under ISO 9001 quality system
Standard
Standard unit includes the stainless steel resistor assembly plus all the required insulators, internal connections and hardware installed in a standard safety enclosure. Neutral Grounding Resistor units are completely assembled, prewired, and tested at our facility. For shipping all units are crated for added protection and ease of handling.
Enclosure Options
•Stainless steel, cold rolled plate construction. Custom paint finish is available.
• Top or side mounted entrance bushing(s).
• Screened covers for indoor applications.
• Support stands for elevating the enclosure above ground.
