[0064] Specifically, the support body 1 is a support formed by a prism, a cylinder or a rod, one end of which is set on the ground of the work site. An installation point for inserting the support body 1 can be pre-set on the ground of the work site. The support body 1 is assembled in the installation point to ensure that the support body 1 is in a vertical state. The hanging parts 2 are arranged at intervals along the length direction of the support body 1 for carrying the test cable. Among them, the hanging parts 2 closest to the near-ground end are arranged at intervals from the ground, leaving a height space to prevent the suspended test cable from contacting the ground.

[0065] The inside of the bracket body 1 is also provided with a threading hole and a threading channel for the wire to pass through to realize the electrical connection of the warning component 3. In order to achieve portability and lightness, the bracket body 1 can also be a hollow structure.

[0067] Specifically, in order to enable the test cables to be flexibly overlapped and hung on the bracket body 1 to prevent contact with the ground, the hanger 2 can be installed on the bracket body 1 according to actual use requirements. Through the symmetrical or staggered or coiled setting of the intervals, all the redundant test cables can be carried on the hanger 2, which is convenient for the centralized collection of the test cables. Since the test cables are placed in a centralized manner, the space occupied by the test cables is reduced, thereby reducing the area of ​​the safe area, reducing the occupancy of the test area, providing more activity space for personnel, and also reducing the risk of mistakenly entering the test area.

[0068] Furthermore, in some embodiments, the bracket body 1 is composed of a plurality of strip-shaped members, and the plurality of strip-shaped members are arranged obliquely so that one end thereof converges at a point to form a distal end, and the other end forms a proximal end, and the proximal end is placed on the end surface to provide stable support for the bracket body 1; the hanging parts 2 are arranged at intervals along the length direction of the strip-shaped members.

[0069] Specifically, the bracket body 1 is a frame body composed of a plurality of strip-shaped members, and has a more stable structure. The end near the ground can be directly placed on the ground to provide support for the device body.

[0071] Further, in some embodiments, the hanging member 2 is a rod and / or a hook member, which is used to hang the cable;

[0072] A buckle is also provided on the hanging member 2, one end of the buckle is hinged to the hanging member 2, and the other end is movably connected to the hanging member 2, and the buckle cooperates with the hanging member 2 to fix the cable.

[0073] Specifically, in order to ensure that the test cable is stably mounted on the hanging member 2 to prevent it from slipping, the hanging member 2 is configured as a long strip-shaped rod, one end of which is connected to the bracket body 1, and the other end extends away from the bracket body 1; wherein the extension direction can be horizontal extension or inclined upward extension; so that after the test cable is connected to the high-voltage generator and the high-voltage electrical equipment to be tested, the excess length of the test cable is mounted on the hanging member 2.

[0074] In order to prevent the test cable from slipping during power-on, the hanger 2 can also be in the form of a hook, provided with an arc-shaped depression, so that the cable can be placed in the depression, thereby improving the stability of the test cable mounted on the hanger 2.

The detachable connection method can be plug-in, bolt connection, mortise and tenon connection, etc.

[0079] Among them, when the test cable is placed on the hanging part 2, in order to avoid the instability of the device body due to the center of gravity of the device body being too high above the ground, thereby preventing the device body from tipping over and causing high-voltage discharge when the test cable contacts the ground, a cavity is provided in the base 11, and the cavity is filled with heavy objects such as sand and bricks to increase the weight of the base 11, thereby improving the stability of the device.

[0080] A tray is also provided on the base 11, and a tray ring is provided around the base 11.
