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, which includes a casing and a first spring, feet are fixed at the four corners of the bottom of the casing, a power supply chamber is opened inside the casing, and the casing is close to the top of the power supply chamber A control room is provided, wherein the power supply room and the control room are separated by a partition, the bottom of the power supply room is fixed with a mounting seat, and the upper end of the mounting seat is provided with a mounting groove, and the mounting seat is close to the mounting groove. Both sides of the bottom are provided with ball grooves, and balls are arranged inside the ball grooves. The three-level active power filter is provided with a stop bar and a first spring to move the battery. When the battery enters the installation slot, the battery presses the stop bar into the bar slot, the first spring is compressed, and the battery drives the sliding plate into the slot. Inside the chute, when the battery completely enters the inside of the installation slot, the first spring will pop out the stopper bar to prevent the battery from moving back, so that the battery can be fixed inside the installation slot.
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...
