間検出装置用制御箱の動作試験装置。[Scope of Claim for Utility Model Registration] 1. The time from when power is supplied until the automatic switch is turned on is defined as X time period, and the detection time for detecting a faulty section after the automatic switch is turned on is defined as Y time period, and the power supply is The period from when the power supply runs out until the automatic switch opens is the Z1 time period, and if the power outage continues for a specified period of time or more after the power supply stops within the Y time period, the automatic switch will not be turned on. The time it locks into the current state is the Z time limit, the time from detecting a ground fault to outputting a command to open the automatic switch is the ground fault relay operation time limit, and the automatic switch is controlled based on these time limits. An operation test device connected to a fault section detection control box, comprising: a connector for receiving signals for measuring the time of each of the time periods from the fault detection control box; 1. An operation test device for a control box for a fault section detection device, comprising: a measuring means for measuring the time; and a display means for displaying the time measured by the measuring means. 2. Measuring means for measuring the X time period and Y time period in the closing mode, the Z1 time period and Z time period in the open mode, and the earth fault relay operating time period in the earth fault mode, and the time measured by the measuring means. 2. The operation testing device for a control box for a fault section detection device according to claim 1, further comprising display means for displaying the following.
