Problems solved by technology

Usually, the design of the front compartment of the cabinet meets the protection requirements through the partition board and the front door. The inverter unit is installed on the partition board. , the air outlet and the heat dissipation window are exposed and communicated with the outside. The dust and water mist in the rear compartment may penetrate into the front compartment and affect the protection of the inverter unit.

Abstract

The invention discloses a high-protection frequency converter. The high-protection frequency converter comprises a cabinet, a partition board, a frequency converter unit, a radiator and a radiating substrate, wherein the partition board is located in the cabinet and divides inside of the cabinet into a front bin and a back bin; the radiating substrate is located in the front bin and is in sealed connection with the partition board through a sealing element; the frequency converter unit is arranged on the front side of the radiating substrate; the partition board is provided with a through hole allowing penetration of the radiator, the radiator is arranged on the back side of the radiating substrate, and the sealing element is located on the periphery of the radiator. According to the high-protection frequency converter, the radiating substrate is arranged in the front bin and is in sealed connection with the partition board through the sealing element, the frequency converter unit is arranged on the front side of the radiating substrate, so that the front bin and the back bin on two sides of the partition board are completely isolated through the sealing element and the radiating substrate, and the protection level is further increased; ventilation between the front bin and the back bin is avoided, heat energy of the front bin is totally conducted to the back bin through the radiator, and the radiation efficiency is improved; meanwhile, mounting of the whole frequency converter unit is facilitated, and the mounting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of frequency converter protection, and more specifically relates to a high-protection frequency converter. Background technique [0002] At present, in order to achieve high protection, the inverter unit is installed in the cabinet. The cabinet is divided into upper and lower parts. The partition divides the upper part into front and rear compartments. The inverter unit is in the front compartment, and the radiator is in the rear compartment. There are through holes on the partition to ensure the flange installation of the radiator. In this way, heat dissipation and protection are separated. The rear cabin is an air duct design cabin, which mainly meets the heat dissipation requirements. [0003] There is an inverter unit in the front compartment. In order to ensure the normal operation of the inverter unit, the front compartment is required to meet higher protection requirements, such as dustproof, waterp...
