[0002] When conducting high-voltage electrical tests (such as cable shock wave tests, cable series resonance tests, etc.), one end of the test line needs to be connected to the test device, and the other end needs to be connected to the phase cable to be tested. The other two phase cables need to be short-circuited and grounded. For example, after testing the A-phase cable, the A-phase cable and the test equipment need to be discharged with a discharge rod, and then the short-circuit wire between the BC phases is removed, the AC phase is short-circuited and grounded, and then the test line is connected to the B-phase cable.

[0026] Example 1

[0027] As shown in the figure, a high-voltage electrical test wiring adapter device includes a test box, a test panel, a first test button, a second test button, a third test button, a first wiring port, a second wiring port and a third wiring port; the test panel is installed on the top surface of the test box; the second wiring port is installed in the middle of the test panel, the first wiring port is installed on the left side of the second wiring port, and the third wiring port is installed on the right side of the second wiring port; the first test button is installed on the upper side of the first wiring port, the second test button is installed on the upper side of the second wiring port, and the third test button is installed on the upper side of the third wiring port.

[0028] The working principle of this embodiment:

[0029] The test panel is installed on the top surface of the test box, and from left to right are the connection port for the A-phase cable (first connection port), the connection port for the B-phase cable (second connection port), and the connection port for the C-phase cable (third connection port). A test button is installed on the upper side of each connection port to control the test of the corresponding phase cable. Press a phase test button, such as pressing the A-phase test button, the transfer switch will be activated, the A-phase cable will be connected to the test equipment, and the BC phases will be automatically short-circuited and grounded. Start the test equipment to test the A-phase cable. Press the disconnect discharge button again, the connection between the A-phase cable and the test equipment and the short-circuit and grounding between the BC phases will be automatically disconnected, and the cable and the test equipment will be automatically discharged. The same applies to the BC phase test.

[0030] The first connection port (A-phase cable connection port): used to connect the A-phase cable. When testing the A-phase cable, it is connected to the test equipment through the transfer switch to realize the test function of the A-phase cable. The second connection port (B-phase cable connection port): connected to the B-phase cable. When testing the A-phase or C-phase, the B-phase cable will cooperate with other phases to perform short-circuit grounding and other operations. The third connection port (C-phase cable connection port): connected to the C-phase cable. When testing the C-phase cable, it is connected to the test equipment and cooperates with other phases to perform corresponding operations in the non-test state.

[0031] As shown in Figure 2, KA1 SAB1, KA2 SB2, and KA3 SB3 on the right side of the figure are the A, B, and C three-phase test buttons (labeled 2). Press the A-phase test button, the A-phase cable (the A-phase live wire in the figure) is tested, and the adjacent BC phase is grounded. The BC test is the same. When the A-phase test button is pressed, the transfer switch is activated, the A-phase cable is connected to the test equipment, and the BC phase is automatically short-circuited and grounded. The A-phase cable can be tested by starting the test equipment. Press the disconnect discharge button again, the connection between the A-phase cable and the test equipment, and the short-circuit grounding between the BC phases are automatically disconnected, and the cable and test equipment are automatically discharged. The BC phase can be tested similarly.

[0032] Example 2

The switch-off discharge button is used to disconnect the cable from the test equipment and the short-circuit grounding between the BC phases after the test is completed, and automatically discharge the cable and the test equipment.

[0046] The working principle of this embodiment is the same as that of Embodiment 1.

[0047] Example 7

[0052] The working principle of this embodiment is the same as that of Embodiment 1.

[0053] Example 9

[0054] The difference between this embodiment and embodiment 8 is that a handle is installed on the side of the test box.

[0056] In summary, the present invention has the following beneficial effects:

[0057] 1. The present invention realizes the separate testing of three-phase cables by setting specific wiring ports and test buttons, without frequent wiring changes, greatly improving the test efficiency. The operator only needs to press the test button of the corresponding phase to automatically complete the connection between the phase cable and the test equipment and the short-circuit grounding of other phases, simplifying the test process and saving test time.

[0058] 2. The present invention can automatically short-circuit and ground the other two phases when testing a certain phase of the cable, effectively preventing the risk of phase interference and accidental electric shock. For example, when testing the A-phase cable, the BC phase is automatically short-circuited and grounded, ensuring that the operator and the test equipment will not be harmed by the accidental electrification of other phases during the test.

[0059] In addition, a switch-off discharge button is also provided, which can automatically disconnect the cable from the test equipment and short-circuit the phases to ground after the test is completed, and automatically discharge the cable and the test equipment. This function avoids safety accidents that may be caused by residual charge after the test, and further enhances the safety of the test.

[0060] 3. The layout of the test panel of the present invention is reasonable, with connection ports and test buttons for phase A, B, and C cables from left to right. Operators can intuitively find corresponding interfaces and buttons, which is convenient for operation.

[0061] 4. The functional division of the wiring ports provided in the present invention enables the operator to clearly know the function of each wiring port, thus avoiding test failure or safety problems caused by wiring errors. For example, the first wiring port is specifically used to connect the A-phase cable, and plays a specific role when testing the A-phase cable, thereby improving the accuracy and convenience of the operation.

[0062] 5. The present invention ensures the accuracy and stability of the connection between the cable and the test equipment through the automatic action of the transfer switch. At the same time, the reliability of the automatic short-circuit and grounding functions is also guaranteed, reducing the possibility of human operation errors and improving the reliability of the test results.
