The invention provides an FTU and on-column switch on-site detection device, which is arranged in a main box through a terminal strip and a storage battery; a digital display indicator lamp is arranged on the display operation panel; the digital display indicator lamp is connected with a current transformer on the internal wiring; the digital display indicator lamp is connected with the corresponding node of the terminal strip; the aerial plug interfaces are arranged on two sides of the main box and are respectively and electrically connected with the column switch and the FTU through aerial plug patch cords; the line case can be dismantled the location and establish in the main tank for realize the holding to the aviation plug patch cord. This application is through setting up the digital display pilot lamp, realizes detection device on the original mode of connection that does not change FTU and column switch, through detection device's switching, with the running state information visual display of FTU and column switch on the panel, the measurement personnel need not carry a large amount of check out test set and can accomplish the detection, has improved work efficiency greatly, and this detection device is in the same place required instrumentation instrument integration, convenient to use. |
