The existing method for high-voltage equipment diagnostic test requires aerial wiring and stitches,which is not only time-consuming,laborious,but also security risking for personnel. To solve this problem,retractable pole is developed for diagnostic test, which can help avoid the danger of high-altitude operations,save manpower,reduce time of power-off,and fully guarantee personnel safety and the reliability of test results. Practice proves that its application has achieved the desired effect.%指出现有的高压设备诊断性试验方法需在高空进行接线和拆线,不仅费时、费力,而且存在人身方面的安全隐患,为此提出适用于诊断性试验的伸缩式接线杆,可避免高空作业风险,有效节省人力和停电时间,充分保证试验人员安全和试验结果的可靠性。实践表明,其应用情况达到了预期的效果。
