Embodiment approach
[0071] like figure 2 As shown, for case 1, that is, the cable under test is any one of the core of a single-core shielded wire, the core of a multi-core unshielded wire, and the core of a multi-core shielded wire: the core The length of the wire core is 6 meters, and the middle section of the wire core with a length of 5 meters is immersed in the water contained in the constant temperature water tank; the second end of one of the high-voltage end electronic switches is connected to the wire core. Conductor, the clamp is electrically connected to the water in the constant temperature water tank, the electrical connection between the clamp and the water can be realized by clamping the clamp on the constant temperature water tank, and the clamp can be placed in the constant temperature water tank. The water in the water tank can also be realized by putting the metal body clamped by the clamp into the water in the constant temperature water tank;
[0072] For the first case, the...
Embodiment 3
[0078] On the basis of the above-mentioned first embodiment, the third embodiment also adopts the following preferred embodiments:
[0079] like image 3As shown, for case 2, that is, the case where the cable under test is a multi-core unshielded cable: the length of the multi-core unshielded cable is 11 meters, and the length of the multi-core unshielded cable is 10 meters. The middle section is immersed in the water contained in the constant temperature water tank; the second end of the first high-voltage end electronic switch KA1 and the second end of the first ground end electronic switch KB1 are both connected to the multi-core The first core conductor of the unshielded wire, the second end of the second high-voltage end electronic switch KA2 and the second end of the second ground end electronic switch KB2 are all connected to the multi-core unshielded wire. The second core conductor, the second end of the third high-voltage end electronic switch KA3 and the second end ...
