Embodiment Construction
[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0038] like figure 1 As shown, the cable terminal moisture intrusion inspection device is used to quickly test the moisture intrusion phenomenon at the high-voltage power cable terminal in the power system. Its structure and usage are as follows:
[0039] When laying the distribution network cables in the cable trench, the cable terminal moisture intrusion inspection device is arranged at the terminal part. After the alloy casing (4) is in, use the upper screw (5), lower screw (7), left end screw (6) on the left side of the inspection device, and the upper screw (13) and lower screw (16) on the right side to inspect The device is fastened, wherein the upper screw (5), the lower screw (7), and the left end screw (6) are tightly attached to the surface of the waterproof sheath (8), and the upper screw (13) and lower screw (16) are in contact with the met...
