Frequency converter is a kind of electric control equipment which uses frequency conversion technology and microelectronics technology to control AC motor by changing the working power frequency of the motor. Frequency converter is mainly composed of rectifier (AC to DC), filter, inverter (DC to AC), brake unit, drive unit, microprocessor unit of detection unit, etc. Wind power converter is a frequency conversion equipment used in wind power generation.
First of all, let's look at what a wind power converter looks like.
We can see that there are dense bundles and joints everywhere in the variable speed wind turbine power generation system. The insulation protection between these joints can not be separated from the protection of heat shrinkage tube. The space of frequency converter is limited. We can not use a large wind frequency conversion system in a very small wind power equipment. The heat shrinkage tube can reduce the distance between the wire bundle and the wire bundle. Reduce security examples.
Frequency converter can be divided into low-voltage converter and high-voltage converter according to the voltage withstand grade, and the corresponding heat-shrinkable tube can be divided into ordinary heat-shrinkable tube: 600V, 1KV two kinds of pressure withstand grade; medium and high-pressure heat-shrinkable tube withstand grade is: 10KV heat-shrinkable tube, 35KV heat-shrinkable tube and so on.
