摘要
开关柜的运行可靠性直接关系到整个配电网络的供电可靠性,开展开关柜带电检测工作是提高供电可靠性的关键措施之一。暂态地电压检测技术、超声波检测技术、红外检测技术是开关柜带电检测中常用的技术手段,结合实际案例分析3种检测手段的优劣。实际应用情况表明综合利用3种检测手段可及时发现设备缺陷,提高设备运行的可靠性。
The switchgear condition directly affects power supply reliability of distribution network. Live testing for the switchgear is one of the key measures to improve power supply reliability. Transient earth voltage test, ultrasonic test and infrared detection are commonly used in live testing. Advantages and disadvantages of these testing methods are analyzed combined with actual cases. Practical application shows that comprehensive utilization of these methods can detect defects accurately and improve operation reliability of the switehgear.
