Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0022] In the description of the embodiments of the present invention, it should be understood that the terms "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the embodiments of the present invention.

[0023] Below, refer to Figure 1-3 A device, system and method for high-altitude electrical testing operations according to an embodiment of the present invention are described in detail.

[0024] The first embodiment of the present invention provides a device for high-altitude electrical testing operations, which is described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-3As shown, a device for high-altitude electrical testing operations includes a first connecting member, a second connecting member 3, a spherical electrical tester 6 and a magnetic member 7, one end of the first connecting member is used to connect to the high-altitude conveying equipment, and the other end is movably connected to one end of the second connecting member 3, the spherical electrical tester 6 is connected to the other end of the second connecting member 3, and the magnetic member 7 is arranged at the bottom of the spherical electrical tester 6, wherein the first connecting member is made of insulating material, and the second connection is a flexible structure. During the electrical testing operation, the magnetic member 7 is adsorbed on the electrical testing part of the line that needs to be tested, and a positioning module is provided on the first connecting member for obtaining the position information of the electrical testing part during the electrical testing operation.

[0026] In this embodiment, the high-altitude electrical test device can be connected to the high-altitude transport equipment through the first connecting member for electrical test. It should be noted that the high-altitude transport equipment can be a drone or other devices that can conveniently transport the high-altitude electrical test device from the ground to high altitude, such as a support pole. The shape of the first connecting member can be a long strip extension shape, so that there is a certain insulation distance between the spherical electrical tester 6 and the high-altitude transport equipment.

[0027] In this embodiment, the second connecting member 3 is a flexible structure and can be made of a conductive material, such as an iron chain, an iron rope, etc., so that the spherical electroscope 6 can be vertically perpendicular to the first connecting member by its own gravity. The conductive material can pass electricity through the spherical electroscope 6 to achieve the electrical testing condition.

[0028] In this embodiment, the positioning module can be used to obtain the current position information of the spherical electroscope 6. The magnetic component 7 has a magnetic adsorption force. When the spherical electroscope 6 is close to the wire that needs to be tested, the spherical electroscope 6 can be automatically adsorbed on the wire for testing.

Therefore, by providing the connecting hook 5 on the insulating sleeve 2, it is convenient to connect the second connector 3 to the insulating sleeve 2.

The iron chain itself has a certain gravity and can sag naturally. The second connecting member 3 is designed as an iron chain, so that the spherical electroscope 6 can sag naturally, ensuring that the spherical electroscope 6 and the first connecting member are vertically perpendicular, thereby making the position information of the spherical electroscope 6 obtained by the positioning module in the first connecting member more accurate. Further, during maintenance, the staff can find the fault location as soon as possible.

[0035] like Figure 3 As shown, in one embodiment, the magnetic member 7 includes two angular magnets with identical structures, and the two angular magnets are symmetrically arranged at the bottom of the spherical electroscope 6. The magnetic member 7 is set as two angular magnets with identical structures, and is symmetrically arranged at the bottom of the spherical electroscope 6, which can further make the spherical electroscope 6 more stable when adsorbed on the test wire, thereby improving the accuracy of the test information.

[0036] Therefore, the device for high-altitude electrical testing of the present invention solves at least one technical problem in the prior art, such as low efficiency and insufficient safety of the existing electrical testers during electrical testing, and achieves beneficial effects: 1) After the first connecting member and the second connecting member 3 are connected, the spherical electrical tester 6 is connected to the second connecting member 3, and the device can be conveniently connected to the high-altitude conveying equipment through the first connecting member, so that the device can be directly transported to the electrical testing position of the electrical testing wire that requires high-altitude electrical testing through the high-altitude conveying equipment, thereby improving the safety and convenience of electrical testing; 2) The first connecting member is set to an insulating material, which can prevent the voltage from being directly released to the high-altitude conveying equipment to damage the high-altitude conveying equipment during electrical testing, and at the same time, it can avoid safety accidents caused by electric shock to construction personnel during electrical testing, thereby improving the safety of electrical testing; 3) By setting a positioning module on the first connecting member, the location information of the electrical testing part can be quickly obtained. It is convenient for timely maintenance; 4) By setting the second connecting member 3 as a flexible structure, the relative position between the first connecting member and the spherical electroscope 6 can be adjusted by the high-altitude conveying equipment, so that the second connecting member 3 and the spherical electroscope 6 remain perpendicular in the vertical direction, so that the position information of the spherical electroscope 6 obtained is more accurate; 5) By arranging a magnetic member 7 on the spherical electroscope 6, when the high-altitude conveying equipment transports the device to the vicinity of the test site, the spherical electroscope 6 automatically adsorbs on the test wire that needs to be tested, ensuring good contact between the spherical electroscope 6 and the test wire during the test, thereby ensuring the accuracy of the test information; 6) Setting the magnetic member 7 as two angular magnets with exactly the same structure, symmetrically arranged at the bottom of the spherical electroscope 6, can further make the spherical electroscope 6 more stable when adsorbed on the test wire, thereby improving the accuracy of the test information.
