济南变频器发热的原因有哪些

浏览量:   来源:www.bcabb.com  作者:宝川

济南变频器发热是由于内部的损耗而产生的,以主电路为主,约占98%,控制电路占2%.为保证变频器正常可靠运行,必须对变频器进行散热.主要方法有:

Frequency converter heating is caused by internal loss, mainly by the main circuit, accounting for 98%, control circuit accounting for 2%. In order to ensure the normal and reliable operation of the converter, it is necessary to heat the converter.

(1) 采用风扇散热:变频器的内装风扇可将变频器箱体内部散热带走.

(1) Heat dissipation by fan: The inner fan of the converter can take away the heat dissipation inside the converter box.

(2) 环境温度:变频器是电子装置,内含电子元件机电解电容等,所以温度对其寿命影响较大.通用变频器的环境运行温度一般要求-10℃~+50℃,如果能降低变频器运行温度,就延长了变频器的使用寿命,性能也稳定.我们一直忙于变频器的保养.⑴可以延长变频器的使用期⑵电器方面我们可以说减少维修率⑶也可以体现公司的管理,公司的形象!我司保养的具体方案如下:1、 变频器须解体,查看内部是否有异常现象.(如:镙丝松动、焊锡脱落、器件松动、器件烧焦、烧煳现象.) 2、 检查变频器内部易老化器件,如:风扇,功率器件,功率电容,及印板老化现象. 3、 清理变频器内部粉尘,油污,腐蚀性及导体杂质.对主要印板如:主控板,驱动板,开关电源板.采用全新品进口电子清洁剂进行喷洗,去除其老化层及导电物质. 4、 对变频器主要控制部分进行先进的加膜处理.起到防尘,防老化,防导电物质,防水,及腐蚀性物质.

(2) Ambient temperature: Frequency converter is an electronic device, including electrolytic capacitors of electronic components, so temperature has a great impact on its life. Generally speaking, the ambient operating temperature of general frequency converter is - 10 ~50 C. If the operating temperature of frequency converter can be reduced, the service life of frequency converter will be prolonged and its performance will be stable. We are busy with frequency converter all the time. Maintenance. _Can extend the life of the converter_Electrical aspects, we can say to reduce the maintenance rate_can also reflect the company's management, the company's image! Our company's specific maintenance programs are as follows: 1. The converter must be disintegrated to see if there are abnormal internal phenomena. (For example, screw loosening, solder peeling, device loosening, device burning, burning.) 2. Check the ageing devices inside the converter, such as fans, power devices, power capacitors, and the ageing of printed boards. 3. Clean up the dust, grease, corrosiveness and conductor impurities inside the converter. Spray wash the main printed boards such as main control boards, driving boards and switching power boards with new imported electronic cleaners to remove their ageing. Layer and conductive substance. 4. Advanced film-adding treatment for main control part of frequency converter. Dust-proof, ageing-proof, conductive substance-proof, waterproof and corrosive substance-proof.http://www.bcabb.com/
