Precautions for reactive power compensation The neutral point of the compensation capacitor bank should not be directly grounded to avoid the single-phase capacitor of the capacitor bank being broken down and causing a phase-to-phase short circuit in the line. The reactive power compensation device should use an automatic switching device and an over-the-air Voltage protection device to prevent over-compensation and voltage rise from damaging capacitors and other equipment. A series reactor of a certain capacity can be installed on the reactive power compensation capacitor circuit to avoid resonance between the capacitive reactance of the capacitor and the inductive reactance of the system.
The R-type filter reactive power compensation device is mainly used to compensate for AC welding machine loads. The welding machine loads have fast or extremely fast reactive power changes. The reactive power loss changes greatly and is unstable. The three-phase load is unstable. Balanced, contains characteristics such as harmonics.
The effectiveness of filters in suppressing electromagnetic interference in industrial applications not only depends on the design of the filter itself and its actual operating conditions, but also depends to a large extent on the installation of the filter. Nowadays, many industrial productions pay great attention to the installation of equipment, because good installation is equal to half the success. The position of the filter leads and installation is also a very important issue.
This device uses a microcomputer controller to automatically collect, judge and track changes in the system. It uses reactive power and power factor as criteria to automatically and reasonably switch, reduce the number of switching times, and avoid the problems of switching oscillation and reactive power backflow. In this way, the power factor of the system is maintained at the best state. The switching mechanism adopts thyristor switching to meet the requirements of rapid load changes on the switching mechanism.
The power saving effect is obvious, the power factor can be increased to above. It has stable current, improves welding quality, eliminates flicker, makes full use of existing equipment, and reduces basic expenses.
