Frequency converter is the application of frequency conversion technology and microelectronics technology, by changing the motor operating power frequency mode to control the AC motor power control equipment. The inverter is mainly composed of rectifier (AC variable dc), filter, Inverter (DC change AC), braking unit, drive unit, detection unit micro-processing unit and so on. Wind inverters are inverter devices used in wind power generation.

First let's take a look at what wind inverters are like:

We can see that in the variable speed wind turbine power generation system is full of dense wiring harness and joints, these joints between the insulation protection can not be separated from the protection of heat shrinkable pipe, the space of the inverter is limited, we could not be in a very small wind equipment with a large wind frequency conversion system, The heat shrinkable tube can reduce the distance between the wire harness and the wiring harness and reduce the safety example.

Frequency converter According to the pressure rating can be divided into low-voltage inverter and high-voltage inverter, the corresponding use of heat shrinkable tube pressure can be divided into ordinary heat shrinkable tube: Pressure resistance of two kinds of 600V,1KV, medium and high pressure heat shrinkable tube pressure rating is: 10KV heat shrinkable tube, 35KV heat shrinkable tube and so on.

热缩管在风力变频器上的使用

变频器是应用变频技术与微电子技术，通过改变电机工作电源频率方式来控制交流电动机的电力控制设备。变频器主要由整流（交流变直流）、滤波、逆变（直流变交流）、制动单元、驱动单元、检测单元微处理单元等组成。风力变频器是使用在风力发电中的变频设备。

首先我们来看一下风力变频器是什么样的：

我们可以看到在变速风力发电机发电系统中到处都是密密麻麻的线束与接头，这些接头之间的绝缘防护离不开热缩管的防护，变频器的空间是有限的，我们不可能在一个很小的风力设备中用上一个很大的风力变频系统， 热缩管则可以缩小线束与线束之间的相见距，缩小安全举例。

变频器按照耐压等级可以分为低压变频器与高压变频器，相应的使用的热缩管耐压则可分为普通热缩管：耐压为600V，1KV两种；中高压热缩管耐压等级为：10KV热缩管，35KV热缩管等。
