ABB变频器在市场发展以及常见故障及维修解决对策 ABB是一个在欧洲乃至全世界都享有盛誉的，高低压、高低压电器、变压器、、发电设备等等都是它的成熟产品，在电厂、、造纸、等各行各业更是被广泛应用。应该说abb的产品在国内还是得到了广大用户的一致认可。 abb变频器以其稳定的性能，丰富的选件扩展功能，可灵活应用的编程环境，良好的力矩特性，以及可供不同场合使用的多种系列，在变频器市场占据着重要的地位。abb变频器在的市场业绩，大家有目共睹。abb变频器以其强大的效应，和较高的社会认知度，在变频器市场位居前列。 由于abb变频器在市场还是有一个十分庞大的量，包括一些早期使用的acs200，acs300，acs500也已进入故障多发期，在使用中必然会碰到许多问题，以下我们就abb变频器的一些常见故障在这里和广大使用者做一个探讨。 acs300变频器的常见故障 对于acs300的变频器，经常会碰到的故障就是开关电源的损坏，acs300变频器开关电源采用了近似uc3844功能的一块叫lt1244的波形发生器集成块，受工作电压的突变，以及开关电源所带负载的损坏，而导致此集成块的损坏时有发生，由于使用了较长年数，电解电容也到了它的使用年限，那用于滤波的电容也就成了开关电源损坏的直接原因。笔者在维修中会碰到acs300变频器的整流桥经常损坏，也许他们从经济角度考虑，选用了国际整流器公司的一款*紧凑的三相全桥整流器，体积和带载电流都较小，散热也较差，所以在使用一段时间后就会出现损坏。acs300主控板发生故障的几率也是相当高的，控制盘与主板之间的通讯故障，主板cpu故障都时有发生，通常此类故障较难排除。acs300选用了三菱的ipm模块，相对来说故障几率较低，模块损坏，只能更换，但更换前必须保证驱动电路完全正常 。
