伺服板电容击穿故障诊断技术研究
Research on Fault Diagnosis Technology of Capacitor Breakdown of Servo Board
摘要:
在伺服板电容击穿故障的排查过程中，通过分析电路板电容击穿故障，以伺服控制板5242E位号为C150的电容瞬间击穿为例，考虑到电容击穿是因为耐压不足所致，故更换耐压值和电容值更高的电解电容。对伺服板电容击穿故障进行故障诊断，详细分析故障事件发生的具体原因，找出存在的现状问题，提出了解决办法及预防措施，为保证伺服控制板正常运行提供了新思路。
Abstract:
In the investigation of the servo board capacitor breakdown fault, by analyzing the breakdown of circuit board capacitor, taking capacitor transient breakdown of servo control board 5242E C150 as an example, considering that the capacitor breakdown is due to insufficient voltage. Therefore, the electrolytic capacitor with higher voltage resistance and higher capacitance is replaced. Fault diagnosis of capacitor breakdown fault of servo board and detailed analysis of the specific causes of the failure occurred and propose solutions and preventive measures can provide a train of thought for the normal operation of servo control board.
