Resonance elimination controller for intermediate frequency cabinet

Abstract

The invention relates to a resonance elimination controller for an intermediate frequency cabinet. The resonance elimination controller includes the intermediate frequency cabinet, and the controller arranged on the intermediate frequency cabinet, a protection housing is arranged outside the controller, an integrated circuit board is arranged in the protection housing, the front side of the protection housing is provided with a full-touch liquid crystal display screen, a buzzer, an LED lamp, buttons, and a circuit switch are displayed on the full-touch liquid crystal display screen, radiating holes are arranged in the left and right sides of the protection housing, suspension member holes are arranged above and below the radiating holes, and the upper and lower sides of the protection housing are provided with installing holes and terminal holes. The controller provided is simple in structure and reasonable in design, can effectively improve the equipment power supply capability, reduces the current output, improves the electric energy quality, reduces the temperature rising of a transformer in operation, solves the problem of unstable voltage, increases the effective capacity of the transformer, and improves the safe operation coefficient of the transformer.

Description

technical field [0001] The invention relates to an intermediate frequency cabinet, in particular to a special harmonic elimination controller for the intermediate frequency cabinet. Background technique [0002] The controller (English name: controller) refers to the main command device that changes the wiring of the main circuit or the control circuit and changes the resistance value in the circuit to control the starting, speed regulation, braking and reverse of the motor in a predetermined order. Composed of program counters, instruction registers, instruction decoders, timing generators, and operation controllers, it is the "decision-making body" that issues commands, that is, to coordinate and direct the operation of the entire computer system. [0003] The traditional controller is purely a reactive power compensation controller, which relies on reactive power to switch capacitor banks, which has low reliability and no targeted things. It is especially inapplicable in...
