Abstract

[0002] During the normal operation of a power supply line, abnormal fault actions such as mis-tripping and non-tripping often occur. During the on-site troubleshooting process by the power user, it is also often encountered that the current fault cannot be judged as a primary equipment fault or a secondary equipment fault. Since the primary equipment is in live operation, it is impossible to immediately cut off the power for discrimination, resulting in inaccurate judgment or improper handling method, thus increasing the equipment operation and maintenance burden and reducing the power supply reliability. The existing solution is to discriminate the fault by measuring the current value of the internal terminal block of the secondary equipment. This solution can only measure whether there is a fault in the current transmission part inside the secondary equipment, and the measurement of the transmission part from the secondary cable to the secondary equipment cannot be accurate. Therefore, fault misjudgment often occurs, resulting in the need for line power cut maintenance and equipment replacement, affecting the timeliness and causing significant economic losses.

One end of each first cable wire 12 is respectively connected to a wiring terminal of the aviation plug 11, and the other end of each first cable wire 12 is respectively connected to a wiring position 131 of the incoming line end of the terminal block 13. The first cable wire 12 can be a 2.5-square black wire. When troubleshooting current faults on-site, there is no need to cut off the power. Separate a socket of a primary device in the circuit from the aviation plug on the controller side. This socket forms a on-site hanging socket 21. Using the tool for identifying current faults without power-off of the circuit breaker device of the present utility model, connect the aviation plug 11 to the on-site hanging socket 21 of the primary device in the circuit. Use a multimeter to measure the wiring position 132 of the outgoing line end corresponding to the wiring position 131 of the first cable wire 12 that has been connected to the incoming line end of the terminal block 13. If the wiring positions 132 of all outgoing line ends are energized, the primary device is fault-free. If there is a wiring position 132 of an outgoing line end that is not energized, the primary device has a fault. If the fault occurs at the primary device end, it is necessary to coordinate with the power user to cut off the power as planned to replace the primary device and the cable; if it occurs at the secondary device end, there is no need to cut off the power to the line, and only the secondary device needs to be repaired and rectified. Specifically, the first cable wire 12 and a wiring terminal of the aviation plug 11 are welded to each other. The tool for identifying current faults without power-off of the circuit breaker device of the present utility model, because it includes an aviation plug 11, a first cable wire 12, and a terminal block 13. One end of each first cable wire 12 is respectively connected to a wiring terminal of the aviation plug 11, and the other end of each first cable wire 12 is respectively connected to a wiring position 131 of the incoming line end of the terminal block 13.

Just connect the aviation plug 11 to the on-site hanging socket 21. There is no need to cut off the power to the line, reducing economic losses. It can be carried to the on-site for troubleshooting. The overhaul and maintenance time is greatly shortened, reducing the maintenance cost. And it is detected by a multimeter, and the line current value can also be detected in real time during the process.
