Problems solved by technology

[0003] Most of the traditional primary harmonic elimination devices are installed as a single unit, which is not convenient for operators to install, replace, and repair and maintain during later use. Since most of the primary harmonic elimination devices are columnar structures, it is not easy to install

Abstract

The invention discloses a primary harmonic elimination device. The harmonic elimination device comprises a placement cabinet, a wiring plate, a wiring cylinder, a vertical fixed plate, a groove, a horizontal fixed plate, a fixed groove, a fixed block, a fixed bolt, a primary harmonic elimination device, a clamping block, a clamping bolt, a wiring sheet, a hanging plate, a vertical fixed connectionplate, an electric push rod, an outage push rod, an adjustment plate, an adjustment bolt, an insulation plate, a wiring rod, a rotation shaft, a continuous connection rod, a fan shell, a motor, blades, a door fan and a rotation wiring plate. The primary harmonic elimination devices in different types and at different sizes can be fixed by a limitation mechanism; since a main body of the limitation mechanism comprises four fixed grooves and clamping blocks, the fixed grooves are arranged in an annular array way, the clamping blocks are arranged on the fixed grooves, and the primary harmonic elimination device in a columnar structure can be fixed very well; and meanwhile, fixing of the primary harmonic elimination devices in different types and at different sizes is completed by matching amovable horizontal fixed plate, and the harmonic elimination device is relatively wide in application range.

Description

technical field [0001] The invention relates to a harmonic elimination device, in particular to a primary harmonic elimination device, belonging to the technical field of harmonic elimination devices. Background technique [0002] The primary harmonic elimination device is suitable for the nonlinear resistance harmonic elimination damper (resonance eliminator) at the neutral point of the voltage transformer. It is installed on the primary winding of the voltage transformer (voltage change), between the neutral point and the ground Non-linear resistance harmonic elimination damping device, its essence is a high-capacity non-linear resistor, which plays the role of damping and current limiting, and can play a good role in limiting the ferromagnetic resonance of voltage transformers. The general primary harmonic elimination device The top is provided with a connection terminal for accessing the line, and the bottom is provided with a ground terminal. [0003] Most of the tradi...
