Problems solved by technology

[0005] The purpose of the present invention is to provide a three-phase electric power voltage stabilization and harmonic control device, which has the advantages of dehumidification, harmonic suppression, three-phase voltage stabilization and compensation, so as to solve the problems in the existing electric power harmonic suppression and three-phase balance device. Without a dehumidification device, it is easy to cause moisture in the installation of the power harmonic suppression and three-phase voltage stabilizing device, which will affect the internal circuit, and the power harmonic suppression device does not have a compensation device, which will cause a load on the circuit and cause circuit damage.

Abstract

The invention discloses an electric power three-phase voltage stabilization and harmonic suppression device, and relates to the technical field of electrical equipment. The device comprises a three-phase voltage stabilization and compensation device cabinet, wherein a touch display panel is fixedly mounted on the front surface of the cabinet, an emergency stop switch located on the right side of the touch display panel is fixedly mounted on the front surface of the cabinet, and a partition plate is fixedly mounted in the cabinet. According to the power harmonic suppression and compensation device, the ventilation fan is prevented from being collided, and the partition plate enables airflow entering from the air inlet to pass through the activated carbon filter plate, enter the cabinet andbe discharged from the air outlet, so that moisture in air is adsorbed by activated carbon so as to achieve the dehumidification effect; and the threaded rod is matched to drive the movable ring to move, so that the supporting rod drives the positioning ring to move, the positioning rod is separated from the fixing block and retracts into the fixing frame, and the effect of conveniently taking down the filter screen is achieved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a power three-phase voltage stabilizing and harmonic control device. Background technique [0002] Since the effective component of the AC power grid is a single frequency of the power frequency, any component different from the power frequency can be called a harmonic. Since the sinusoidal voltage is applied to the nonlinear load, the fundamental current is distorted to generate harmonics, and the harmonics The power loss of the power grid is increased, the life of the equipment is shortened, the grounding protection function is abnormal, the remote control function is abnormal, the line and equipment are overheated, especially the third harmonic will generate a very high neutral line current, making the zero line current of the distribution transformer even If the current value of the phase line is exceeded, it will cause unsafe operation of the equipment, and caus...
