for 6 ~ 35kV neutral point grounding grid electromagnetic voltage transformer Eliminate harmonic or damp the ferroresonance
Brief introduction :
Harmonic Elimination Product for 6 ~ 35kV neutral point grounding grid electromagnetic voltage transformer (hereinafter referred to as PT): When no load or less load occurs to the bus, due to the closing charge or ground fault on operation time vanishing, it’ll make voltage transformer saturation and further lead to ferroresonance over-voltage, relatively voltage instability, and the ground to indicate the malfunction, the PT high-voltage fuse burns, and other anomalies can even lead to PT burn and spark other serious accidents.
LXQ(LXQ3,LXQ4) type harmonic elimination is used for neutral point ungrounded system, damping caused by voltage transformer ferroresonance as system shocking, to protect PT from damage, and ensure the security of electricity supply system.
LXQ(LXQ3,LXQ4) Harmonic Elimination, as the core of the nonlinear resistance with the electrical performance, ultrafine SIC manufacturing, while the surface structures of nonlinear resistance special treatment, it has small size, light weight, heat dissipation, easy to install and so on.
electric character:
Normal service conditions:
1.The ambient air temperature is no higher than +40 degree. no lower than -40 degree.
2.Power frequency 48Hz~62Hz
3.The earthquake intensity does not exceed 8 degrees
