6.4 Component Replacement
Wear-out faults are related to endurance period and service life. The endurance period
largely depends on the working conditions.
1. For example, service life of relay is determined by the roughness of the contact
surface. Contact current and load inductance are the major factors affecting its service
life.
2.Capacitor inside the inverter is used mainly as a smoothing filter. Due to the
chemical reaction that takes place internally, its service life is greatly affected by the
temperature. Generally speaking, rising of 10
℃
in temperature reduces the service
life of an aluminum electrolytic capacitor by half, which also affects the service life of
inverter. When the inverter is used under high temperature, the aluminum electrolytic
capacitor may suffer from wear-out faults prior to other components in normal status
and must be replaced to extend the service life of inverter.
