Anti-harmonic-wave reactive compensation capacitor module apparatus

Abstract

The invention relates to a reactive power compensator, especially to an anti-harmonic-wave reactive compensation capacitor module apparatus. The anti-harmonic-wave reactive compensation capacitor module apparatus comprises a breaker module, a current transformer module. A dynamic noncontact switch module, a reactor module, a harmonic wave protector module, a switch signal input terminal module, a compensation capacitor module and a heat dissipation fan, which are all connected together. Power factors of a system is increased, energy consumption is reduced, the voltage quality of a power grid is improved, equipment is stabilized to function, the electric quality is improved while the power supplying efficiency of a power grid is increased, and harmonic waves generated by a load can be effectively filtered. Therefore, harmonic waves of a low voltage distribution network for civil uses are inhibited within a national standard, harmonic wave currents are prevented from damaging power supplying equipment, and the electric quality of a low voltage distribution network for civil uses and the safety of the network are improved. Furthermore, the installing space of equipment is effectively saved, the equipment is made to have a concise internal structure and is convenient to maintain, the reactive compensation apparatus is improved in reliability and safety, and maintenance technical difficulties are minimized.

Description

technical field [0001] The invention relates to a reactive power compensation device, in particular to an anti-harmonic reactive power dynamic compensation device. Background technique [0002] At present, the application of power electronic equipment is becoming more and more common. Power electronic devices are indispensable in the production process, such as personal computers, air-conditioning equipment, lighting equipment, elevators, DC motors, frequency converters, intermediate frequency induction furnaces, medical equipment, etc. The harmonics generated by these non-linear electrical equipment can lead to waste of electric energy, reduce system capacity, accelerate equipment aging, reduce productivity, and can cause failure of the power distribution system itself or other equipment connected to the system. In the case of severe harmonics, ordinary capacitive reactive power compensation devices and dynamic capacitive reactive power compensation devices commonly used in...

Problems solved by technology

Harmonics generated by these non-linear electrical equipment can lead to waste of electrical energy, reduce system capacity, accelerate equipment aging, reduce productivity, and can cause failure of the power distribution system itself or other equipment connected to the system

In the case of severe harmonics, ordinary capacitive reactive power compensation devices and dynamic capacitive reactive power compensation devices commonly used in low-voltage distribution networks do not have filtering functions, not only have no suppression of harmonics in civil low-voltage distribution networks, but also It will amplify the harmonics and increase the harmonic interference coefficient
