A multifunctional outer cover for a frequency converter and a frequency converter

Abstract

The invention discloses a multifunctional outer cover and a frequency converter for a frequency converter, which relates to the working field of the frequency converter. The invention comprises a bottom plate, a shock absorbing mechanism is fixed on the bottom plate, and a support plate is arranged at the upper end of the shock absorbing mechanism. The shock absorbing mechanism comprises a first shock absorbing spring, a lower pressure plate and a lower pressure bar; The support plate is provided with a T-shaped groove and a threaded through hole, and the support plate is provided with a protective cover, wherein a fixing mechanism is arranged in the protective cover, and the fixing mechanism comprises a pressing spring and a baffle plate. A rectangular groove is formed on the outer side wall of the protective cover, and a metal plate is arranged in the rectangular groove. A limit mechanism and a limiting mechanism are arranged at that bottom side end of the protective cov, and a heatdissipation mechanism is arranged at the top side end of the protective cover. When the frequency converter is operated, the invention can fix the frequency converter, at the same time, the vibrationeffect generated can be effectively alleviated, and the heat generated when the frequency converter is operated can be discharged. In addition, the metal plate which can be opened and closed providedby the invention can effectively prevent electromagnetic wave interference, and at the same time prevent the frequency converter from being faulty when working, so that the invention is convenient toopen and close and timely check and maintain.

Description

technical field [0001] The invention relates to the working field of frequency converters, in particular to a multifunctional cover for frequency converters and frequency converters. Background technique [0002] 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. There are many factors that need to be paid attention to when using the frequency converter, such as the physical environment such as operating temperature and ambient temperature, and the electrical environment such as electromagnetic interference, etc. At the same time, the vibration effect generated by the frequency converter itself must be considered. [0003] In the prior art, those skilled in the art have been able to fully control the above-mentioned factors, but they cannot integrate them perfectly so that they can function at the same time. For examp...
