Power harmonic suppression and compensation device

Abstract

The present invention relates to the technical field of electrical equipment and discloses a power harmonic suppression and compensation device. The device comprises an APF (Active Power Filter) machine cabinet; a touch display panel is fixedly mounted on a front surface of the APF machine cabinet; an emergency stop switch located on the right side of the touch display panel is fixedly mounted onthe front surface of the APF machine cabinet; a partition plate is fixedly mounted at an interior of the APF machine cabinet; a fixed frame is movably sleeved in the middle of the partition plate; anactivated carbon filter plate is fixedly sleeved on the inner side of the fixed frame. According to the power harmonic suppression and compensation device, a ventilation fan is prevented from being collided, and the partition plate enables an airflow entering from an air inlet to pass through the activated carbon filter plate and to enter the APF machine cabinet, and enables the airflow to discharge from an air outlet so that moisture in air is adsorbed by activated carbon to achieve the dehumidification effect; a movable ring is driven to move in cooperation with a threaded rod so that a support rod drives a locating ring to move; the locating ring is enabled to separate from a fixed block and retract into the fixed frame so as to achieve the effect of facilitating in removal of a filternet.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a power harmonic suppression and compensation 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 cause local paralle...
