由于电力电子技术和微电子技术的快速发展，变频器改型换代速度也比较快，不断推出新型产品，性能不断提高，功能不断充实、增强。现在国内市场销售的变多，如Danfoss、ABB、SIEMENS、GE、Schneider等等，虽然种类繁多，但功能及使用上却基本类似。总的来讲，其使用、维护保养及故障处理方法是基本相同的。在实际应用中，变频器受周围的温度、湿度、振动、粉尘、腐蚀性气体等环境条件的影响，其性能会有一些变化。如使用合理、维护得当，则能延长使用寿命，并减少因突然故障造成的生产损失。如果使用不当，维护保养工作跟不上去，会出现运行故障，导致变频器不能正常工作，甚至造成变频器过早的损坏，而影响生产设备的正常运行。因此日常维护与定期检查是必不可少的。 General Radio 1422-N Precision Capacitor, 1150pF, GR
