3HAC3180-1 Microcomputer detuning device

ABB 3HAC3180-1 microcomputer tuning eliminator is mainly used in power system.

In the power system, ferroresonance is a frequent problem, it will be generated in any system of 3 to 220 kV, especially in the 35 kV and below power grid, almost all internal overvoltage accidents are caused by ferroresonance. The overvoltage generated by ferromagnetic resonance lasts for a long time and may even exist for a long time. When the frequency division resonance, the general overvoltage is not high, but the current of PT is large, which is easy to make PT overheat and explosion; When the fundamental wave and frequency multiplier resonance, the general current is not large, but the overvoltage is very high, which often causes damage to the insulation of the equipment, resulting in malignant accidents.

ABB 3HAC3180-1 microcomputer tuning eliminator can monitor the voltage and frequency at the PT opening triangle of the voltage transformer in real time. When ferromagnetic resonance occurs, the device can instantly start the contactless tuning eliminator, generating strong damping, thereby eliminating the ferromagnetic resonance 1. In addition, the device can distinguish between external overvoltage, ferromagnetic resonance and single-phase grounding, and adopts high-power, contactless detuning elements, so that the detuning is fast and reliable.

Therefore, the application of ABB 3HAC3180-1 micro-computer detuning device in power system is of great significance for improving system stability, protecting equipment from damage and reducing the occurrence of malignant accidents. However, specific application scenarios and system designs need to be considered based on technical specifications, performance requirements, and compatibility with other devices and systems. In practical applications, you are advised to refer to related technical documents or consult professional technical personnel for more detailed information and suggestions.
