[0022] In an embodiment of the present utility model, Figure 1 and Figure 2 The schematic diagram is provided according to the specific structure of a transposed conductor short circuit rapid detection device of the utility model, as shown in FIG. Figure 1 and Figure 2 As shown, the utility model specifically includes:
[0023] A controller 4, a detector 7, two clamps 1, a plurality of probes 2 and a plurality of relays 5, wherein the plurality of probes 2 are evenly arranged on the two clamps 1, the two clamps 1 are arranged opposite to each other, the clamps are made of insulating materials, and correspond to the enameled flat wires on both sides of the transposed conductor 6 to be detected, respectively, and the transposed conductor 6 to be detected is arranged between the two clamps 1. The probes 2 on the two clamps 1 are respectively located on both sides of the transposed conductor 6 to be detected, each of the probes 2 corresponds to each enameled flat wire in the transposed conductor 6 to be detected, and one end of each probe 2 away from the transposed conductor 6 to be detected is connected to the input end of each relay 5, respectively, the control end of each relay 5 is connected to the controller 4, and the output end of each relay is connected to the detector 7.
[0024] In one embodiment of the utility model, one end of the two clamping plates is provided with an axial hole 12 , and the guide shaft 8 passes through the two axial holes 12 , so that the two clamping plates can rotate around the guide shaft 8 as the center.
[0025] When the utility model is used, the transposed conductor to be tested is clamped between two clamping plates, and the clamping plate angle is adjusted according to the number of enameled flat wires, so that the projection spacing of the probe 2 in the vertical direction increases or decreases, and the spacing between two adjacent probes is equal to the thickness of the enameled flat wire in the transposed conductor 6, so that the first probe on the clamping plate corresponds to the first enameled flat wire, and the nth probe corresponds to the nth enameled flat wire conductor, as shown in the specific example. Figure 2 shown.
[0026] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, the clamping plate is provided with pinholes 11 at intervals, and the pinholes 11 are arranged in a straight line with equal spacing. The probes 2 are installed in the pinholes 11, so that the probes 2 are arranged in a straight line with equal spacing. When the clamping plate 1 is rotated, the projection height of the probes in the vertical direction increases or decreases. When the number of probes is consistent with the enameled flat wires in the corresponding column to be detected, each probe 2 is aligned with the enameled flat wires in the corresponding order, and each probe 2 pierces the corresponding enameled flat wire when the clamping plate 1 is pressed. The setting direction of the axial hole 12 is the same as the setting direction of the pinhole 11. A cutting edge 21 is provided on the top of the probe, and a wiring hole 22 is provided on the tail. The cutting edge 21 is used to cut the paint film of the enameled flat wire, and the wiring hole 22 is connected to the wire.
[0027] In one embodiment of the present invention, the controller 4 is a PLC controller. The detector 7 is a short circuit detection device, which can be a multimeter or the like.
[0028] The common contact of the relay is connected to the probe, and the normally open contact of the relay is connected to the positive pole of the detector. Furthermore, when performing a path detection, one end of the transposed wire to be detected is connected to the negative pole of the detector. When performing a short circuit detection, the normally closed contact of the relay is connected to the negative pole of the detector.
[0029] Specific as Figure 5 As shown, the control end of the relay is connected to the controller output end Y0, Y1, Y2, etc., and the control relay is in the on state (on) or the off state (off). The input end of the relay is connected to the probe 2, and the output end of the relay is connected to the detector 7. Specifically, when the relay is in the on state, the output end is connected to the positive probe of the detector 7, and when the relay is in the off state, the output end is connected to the negative probe of the detector 7.
[0030] When the utility model is used, the transposed conductor to be tested is first installed between two clamping plates, and the angle between the two clamping plates is adjusted by rotation so that the first probe on the clamping plate corresponds to the first enameled flat wire, and the nth probe corresponds to the nth enameled flat wire. The two clamping plates are pressed inward, and the probe pierces the paint film on the side of the enameled flat wire in the transposed conductor and contacts the conductor to form a connection. Through multiple conductors wrapped with insulated copper wires, the relay is connected to the controller and the detector.
[0031] When performing a path detection, one end of the transposed wire is wrapped with conductive cloth and connected to the negative pole of the detector. The controller selects the relays one by one, and the detector is connected to the detection circuits at both ends of the enameled flat wire. The detector determines whether it is conductive or not.
[0032] When performing short circuit detection, remove the conductive cloth on the transposed wire, the controller selects one of the relays, and the detector detects the signal returned by other enameled flat wires. If a return signal is found, it is a short circuit. If no short circuit is found within the specified time, continue to detect other enameled flat wires until all tests are completed.
[0033] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
