Abstract

The invention discloses an outdoor moistureproof mounting box for a frequency changer and relates to the field of electrical equipment. The outdoor moistureproof mounting box comprises a box body which comprises a base, a mounting chamber and an upper cover, the base is arranged at the bottom of the mounting chamber, the upper cover is arranged on the upper portion of the mounting chamber, the base comprises supporting feet, a moistureproof partition, a fan and multiple heating pipes, the supporting feet are arranged at the bottom of the base, the moistureproof partition is arranged on the upper portion of the base, the fan is arranged on the upper portion of the moistureproof partition, and the heating pipes are hollow pipes and communicates the mounting chamber with the base. The box is used for solving the problem that the frequency changer is prone to be affected with moisture in mounting boxes in the prior art; through the outdoor moistureproof mounting box, the problem that the frequency changer mounted inside the box body is prone to being affected with moisture can be effectively prevented, service life of the outdoor frequency changer is prolonged, and electricity using safety is further improved.

Description

[0001] Technical field: [0002] The invention relates to the field of electrical equipment, in particular to an outdoor moisture-proof installation box for frequency converters. [0003] Background technique: [0004] 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 IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In addition, the frequency converter has many protection functions , such as overcurrent, overvoltage, overlo...
