Coefficient of K transformer
Product introduction
Coefficient of K transformer is used for nonlinear load power supply transformer, power network and user load factor of three harmonic and other odd harmonics exist, three times harmonic will cause the increase of neutral line current, other times the odd harmonics and three times harmonic will cause additional heating coefficient of transformer winding, K is specifically designed for can withstand the harmonic transformer, wherein K coefficient rated standard value is 4,9,13,20,30,40,50.
Application field
The K coefficients of transformer is mainly applied in the low voltage distribution, oil drilling platform, large power distribution room, bank (government) room, fire (nuclear) power plant, storage equipment, seawater desalination, mechanical equipment etc..
Technical parameters
1, the power range: less than 1600KVA
2, the dielectric strength: winding - winding, winding - shielded, winding - 3000VAC/50Hz/60s without flying fox breakdown
3, insulation resistance: through screw - 500VDC, insulation resistance value is more than 100M Omega
4, the transformer noise: less than 65dB (and transformer horizontal distance point 1 meters test)
5, protection grade: IP00 (optional cabinet)
6, insulation grade: H
7, product executive standard: UL1561:2000 dry type general power transformer, IEEE C57.110-2008
The use of the environment
1, an altitude of more than 1000 meters, more than 1000 meters derating.
2, the operating environment temperature between -5 DEG ~40 DEG C, relative humidity of not more than 90%.
3, no harmful gas, inflammable and explosive materials, no conductive dust.
