Abstract

The invention relates to the technical field of high-voltage frequency converters, and discloses a high-voltage frequency converter protection device which comprises a shell, a protection cover is arranged on the outer side of the shell, the protection cover is detachably installed on the inner side of the shell, a control assembly is arranged in the shell and fixed in the shell, and the protection cover is detachably installed on the inner side of the shell. The high-voltage frequency converter protection device comprises a shell, a control assembly is arranged in the shell, a protection part is arranged between the control assembly and the shell, the protection part is installed between the shell and the control assembly, the protection part comprises a protection box, a compression spring, an insertion rod, a clamping head and an insertion hole, and the protection box is movably arranged in the shell. The protection device can be used for protecting the frequency converter, and compared with a common protection device, the protection device provided by the invention has the advantages that surrounding components can be protected after explosion, and surrounding fire can be avoided.

Description

technical field [0001] The invention relates to the technical field of high-voltage frequency converters, in particular to a high-voltage frequency converter protection device. Background technique [0002] High-voltage and high-power variable frequency speed control devices are widely used in various fans, pumps, compressors, rolling mills, etc. [0003] The existing inverter will generate a lot of heat during use, which will lead to an increase in the internal temperature, and due to different heat dissipation effects during use, the inverter is prone to explosion, resulting in damage, and the explosion is often accompanied by A fire will affect the surrounding environment and may cause personal injury. SUMMARY OF THE INVENTION [0004] (1) Technical problems solved [0005] Aiming at the deficiencies of the prior art, the present invention provides a high-voltage inverter protection device, which has the advantages of being able to protect surrounding components after...
