Frequency converter all-in-one machine and working method thereof

Abstract

The invention discloses a frequency converter all-in-one machine and a working method thereof. The machine comprises a frequency conversion box. A waterproof assembly is mounted at the bottom of the frequency conversion box. A box door is fixed to one side of the frequency conversion box through a hinge, vent holes are formed in the center of the top and the center of the bottom of the frequency conversion box, a lower clamping base is rotatably connected into the vent hole in the bottom of the frequency conversion box through a bearing, the lower clamping base is fixed to the center of the bottom of a lower rotary disc, and equipment positioning rods are fixed to the periphery of the top of the lower rotary disc. The machine is novel in structure, ingenuous in concept, the separated installation of the high heating element and the low heating element is realized. Mutual interference of heat generated in the working process of the high heating element and the low heating element can beeffectively avoided, the service life of the high heating element and the low heating element is not influenced, centralized arrangement of the heat dissipation elements is facilitated, the heat dissipation elements are centralized in the high heating element area, and the heat dissipation efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of frequency converters, in particular to a frequency converter integrated machine and a working method thereof. Background technique [0002] With the development of society and the continuous improvement of industrial automation, frequency converters have been widely used. The frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor's working power supply. The frequency converter is mainly composed of rectification (AC to DC), filter, inverter (DC to AC), braking unit, drive unit, detection unit, micro-processing unit, etc. The frequency converter adjusts the voltage and frequency of the output power supply by switching off the internal power devices, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy s...
