Description

Technical Field

[0001] The utility model belongs to the technical field of power filters, and in particular relates to a novel integrated power filter. Background Art

[0002] APF, or active power filter, is a new type of power harmonic control equipment made of digital signal processing technology based on high-speed all-digital control using modern power electronic technology. It consists of two main parts: the command current operation circuit and the compensation current generation circuit. Compared with the traditional passive filter (which is equivalent to providing a very low impedance channel close to 0 for the harmonic current to prevent the harmonic current from being injected into the system), the active filter realizes the dynamic filtering of each harmonic through the IGBT inverter module.

[0003] At present, during the operation of the existing integrated power filter, since it mainly controls electricity, it will generate energy dissipation during use, thereby generating a large amount of heat. Generally, a large number of heat dissipation holes are set on the outside of the shell of the integrated power filter to achieve the purpose of rapid heat dissipation. Since the inside of the equipment is connected to the outside world, external dust will enter the equipment through the heat dissipation holes and adhere to the components, affecting the heat dissipation effect of the components themselves, causing the components to overload and greatly reducing the service life and operation efficiency of the equipment. For this reason, we propose a new integrated power filter. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. A heat dissipation groove is opened at the bottom of the filter body, and heat is transferred to the inside of the heat dissipation groove by means of heat conduction plates, cooling sheets and heat dissipation fins. The inside of the heat dissipation groove is ventilated and cooled by the intake fan and the exhaust fan, so as to achieve the purpose of efficient heat dissipation.
