Problems solved by technology
[0005] The purpose of the present invention is to provide a three-level active power filter to solve the problem that the current three-level active power filter proposed by the above-mentioned background technology is inconvenient to install and install the internal storage battery, and the three-level When the active power filter is in use, it generates a lot of heat, which needs to be cooled by air cooling or water cooling. The existing air cooling structure will bring dust in the outside air into the box, which is inconvenient to use.

The invention discloses a three-level active power filter. The filter comprises a housing and a first spring; supporting legs are fixed to the four corners of the bottom of the housing; a power supplychamber is formed in the housing; a control chamber is formed in the top, close to the power supply chamber, of the housing, wherein the power supply chamber and the control chamber are isolated through a partition plate; a mounting base is fixed to the bottom of the power supply chamber, a mounting groove is formed in the upper end of the mounting base, ball grooves are formed in the two sides,close to the bottom of the mounting groove, of the mounting base, and balls are arranged in the ball grooves. According to the three-level active power filter, the filter is provided with a stop leverand the first spring, and a storage battery is moved; when the storage battery enters the mounting groove, the storage battery presses the stop lever into a stop lever groove, the first spring is compressed, the storage battery drives a sliding plate to enter a sliding groove; when the storage battery completely enters the mounting groove, the first spring pops up the stop lever, so the storage battery is prevented from moving back, and the storage battery is conveniently fixed in the mounting groove.
Description
technical field [0001] The invention relates to the technical field of power filters, in particular to a three-level active power filter. Background technique [0002] Active power filter is a new type of power electronic device used to dynamically suppress harmonics and compensate reactive power. It can compensate harmonics and reactive power that vary in size and frequency. The internal settings of active power filters There is power. [0003] Although there are many types and quantities of the current three-level active power filters, there are still some problems in the existing three-level active power filters, which bring certain problems to the use of three-level active power filters. the inconvenience. [0004] When the existing three-level active power filter is in use, it is inconvenient to install and repair the internal battery, and when the three-level active power filter is in use, it generates a lot of heat, which needs to be cooled by air cooling or water c...
