3HAC3180-1 Voltage transformer

ABB 3HAC3180-1 is a micro-computer tuning suppression device, which is mainly used in the elimination of ferromagnetic resonance of voltage transformer (PT) in power system.

Ferroresonance is a common and difficult problem in power systems. It can occur in systems of any voltage class, but especially in power grids of 35 kV and below. Ferromagnetic resonance may not only cause damage to equipment insulation, but also cause serious accidents. Therefore, the elimination of ferromagnetic resonance is essential to ensure the stable operation of the power system.

ABB 3HAC3180-1microcomputer tuning eliminator monitors the voltage and frequency at the PT opening triangle of the voltage transformer in real time. When the ferromagnetic resonance is detected, it can quickly start the tuning eliminator and effectively eliminate the resonance, thus protecting the stable operation of the power system.

Therefore, ABB 3HAC3180-1microcomputer detuning device has a wide range of application prospects in power systems, especially in those occasions that require high power stability and safety, such as substations, power plants and transmission and distribution networks. By using this device, the harm caused by ferromagnetic resonance can be effectively reduced, and the reliability and safety of power system can be improved.

ABB 3HAC3180-1 can quickly eliminate the characteristic frequency of three frequency, two frequency, power frequency and triple frequency of ferroresonance, and can distinguish between external overvoltage, ferroresonance and single-phase ground. It uses high-power, contactless detuning elements to ensure rapid and reliable detuning.

In addition, ABB 3HAC3180-1 provides a set of passive alarm nodes that can display fault reports (including type, time, voltage value and frequency) when a fault occurs. If you choose a micro printer, you can also print fault reports in time.
