CN103293343A 一种开关密度继电器试验与微水试验接头转换导管 无效 - 撤回

一种开关密度继电器试验与微水试验接头转换导管
摘要：
一种开关密度继电器试验与微水试验接头的转换导管，属于电力系统检修试验装置领域，包括转换导管接头、导管、卡扣、六角螺母、接头，所述的转换导管接头通过导管相连接；所述的卡扣与转换导管接头固定连接；所述的六角螺母固定于卡扣上；所述的接头与微水试验仪器相连接。本发明能够取代传统的密度继电器试验接头，进而提高工作效率。相对于传统试验接头显示出该新型接头的优越性与可靠性，保证检修过程中试验的高效性，保证了供电的可靠性。检修试验过程中密度继电器校验与微水试验更换接头所需总时间，220kV线路耗时总时间由18分钟降到10分钟；66kV线路耗时总时间由10分钟降到6分钟，提高试验效率，减少试验时间。
摘要（英）：

The invention discloses a switching tube for switch density relay test and micro-water test connectors, and belongs to the field of maintenance and test devices for power systems. The switching tube comprises switching tube connectors, a tube, fasteners, hexagon nuts and connectors; the switching tube connectors are connected with each other by the tube; the fasteners are fixedly connected with the switching tube connectors; the hexagon nuts are fixed onto the fasteners; the connectors are connected with micro-water test instrument. The switching tube has the advantages that the traditional density relay test connectors can be replaced, and accordingly the work efficiency is improved; the superiority and the reliability of the novel connectors are displayed as compared with the traditional test connectors, high test efficiency is guaranteed in a maintenance procedure, and the power supply reliability is guaranteed; total required connector replacement time for a density relay test and a micro-water test in the maintenance and test procedure is 10 minutes instead of the original 18 minutes for a 220kV circuit and is 6 minutes instead of the original 10 minutes for a 66kV circuit, the test efficiency is improved, and the test time is shortened.
