Description

Technical Field

[0001] The utility model relates to the field of active power filter processing, and particularly to a cutting device for an active power filter. Background Technique

[0002] An active power filter (APF) is a new type of power electronic device used for dynamic harmonic suppression and reactive power compensation. It can quickly track and compensate harmonics of different magnitudes and frequencies. The reason it is called "active" is that, compared with passive LC filters that can only passively absorb harmonics of fixed frequencies and magnitudes, the APF can sample the load current, separate each harmonic and reactive power, control and actively output the magnitude, frequency, and phase of the current, and respond quickly to cancel the corresponding current in the load, achieving dynamic tracking compensation. Moreover, it can compensate for both harmonics and reactive power and imbalance. During the processing of active power filters, it is necessary to cut the filters, so a cutting device for active power filters is required.

[0003] The prior art patent document with the publication number CN220006197U provides a cutting device for graphite heat exchanger processing, including a workbench. Four corners of the lower surface of the workbench are vertically and fixedly installed with supporting feet. A placement groove is formed in the middle of the upper surface of the workbench. The placement groove is semicircular. A storage frame is fixedly installed in the middle of the lower surface of the workbench. A storage box is arranged in the storage frame. A baffle is vertically and fixedly installed at the top of the front side of the storage box. A scale bar is engraved on the side surface of the storage box. By observing the scale bar on the side surface of the storage box, the baffle is moved to a position matching the required cutting length of the pipe, and then the position of the storage box is fixed by rotating the positioning screw. Then, the pipe to be cut is placed in the placement groove, so that one end of the pipe contacts the baffle, and the required length of the pipe can be cut through the cutting mechanism without the need for workers to measure and mark, improving the cutting efficiency and being suitable for wide promotion and use. However, when the technology of CN220006197U is operating, it is not convenient to quickly fix active power filters of different sizes, not convenient to collect cutting waste, not convenient to stably cut active power filters, and is easily affected by the cutting reaction force and jitter, resulting in unstable cutting.
