Embodiment Construction

[0009] The present invention will be further explained below in combination with specific embodiments.

[0010] An explosion-proof frequency converter for mining, including a frequency converter assembly, the frequency converter assembly is arranged in a box, the box is made of aluminum material, and cooling fins are arranged on the outer surface of the box. A temperature alarm is installed on the box body.

[0011] In the mining explosion-proof frequency converter of the present invention, the frequency converter is first arranged in a box made of aluminum profiles with better heat dissipation performance, and more heat dissipation fins are arranged on the outer surface of the box body to increase the heat dissipation area , so that the heat generated during the use of the inverter can be quickly dissipated. At the same time, a temperature alarm is set on the box. When the temperature of the box reaches the preset alarm temperature, it will sound to remind the operator to ta...

Abstract

The invention discloses a mining explosion-proof frequency converter. The explosion-proof frequency converter for mining includes a frequency converter assembly, and the frequency converter assembly is arranged in a box body, the box body is made of aluminum material, and cooling fins are arranged on the outer surface of the box body. A temperature alarm is installed on the box body. The mine explosion-proof frequency converter of the present invention has simple structure, few components, small volume, convenient movement and long service life. It can ensure that the heat generated during use is quickly dissipated, and it is equipped with a temperature alarm, which is very convenient to use.

Description

technical field [0001] The invention relates to a mining equipment, in particular to a mining explosion-proof frequency converter. Background technique [0002] At present, there are many types of general-purpose inverters, and the technology is relatively mature. However, due to the relatively high requirements for mine use, it must have explosion-proof performance requirements, which allows the heat generated by the mine-used inverter to be dissipated quickly during use, so as not to generate heat accumulation, but there is a hidden danger of explosion Danger. At present, there are also some explosion-proof frequency converters with heat dissipation function, which are mainly cooled by water. This type of frequency converter has a complex structure, high manufacturing cost, and the effect is not obvious when used, so it cannot meet the use requirements for the time being. Therefore, it is extremely urgent to improve the frequency converter in the prior art. Contents of...
