Wall hanging-type filter mounting device

Abstract

The invention discloses a wall hanging-type filter mounting device, which comprises a wall hanging plate. The wall hanging plate is a cubic cavity; the rear surface of the wall hanging plate is a detachable bottom plate; two ends of the left side surface or the right side surface of the wall hanging plate are provided with symmetrical hangers respectively; each hanger is provided with at least onemounting hole; the front surface of the wall hanging plate is provided with a groove; a matched rotating plate is arranged in the groove; the port of the groove is provided with symmetrical connection buckles; the connection buckles are parallel with the groove port; a first groove hole is arranged in each connection buckle; each connection buckle is movably connected with a connection plate; a second groove hole is arranged in the connection plate; the first groove hole and the second groove hole are connected through a vertical plate; the groove is internally provided with a power interface; and the cavity of the wall hanging plate is internally provided with a battery. The groove is used for placing an active filter, and the active filter can be ensured not to fall in the groove. The power interface facilitates power taking by the active filter. the battery provides power for the active filter in a condition in which the power is cutoff.

Description

technical field [0001] The invention relates to an active filter, in particular to a device for installing a wall-mounted filter. Background technique [0002] Active power filter is a new type of special equipment for power harmonic control made of modern power electronics technology and digital signal processing technology based on high-speed DSP devices. It is composed of two main parts: command current operation circuit and compensation current generation circuit. The command current operation circuit monitors the current in the line in real time, converts the analog current signal into a digital signal, and sends it to a high-speed digital signal processor (DSP) to process the signal, separates the harmonic from the fundamental wave, and modulates it with pulse width ( PWM) signal form sends drive pulses to the compensation current generating circuit to drive the IGBT or IPM power module to generate a compensation current equal to the grid harmonic current amplitude an...
