This method may cause glue residue to remain on the metal parts of the cable terminal posts. If it is not cleaned thoroughly, it may cause flashover of the metal parts of the cable terminal posts.

[0004] Elbow-type cable heads are also used to cover the test wires, test clamps, and metal parts of the cable head terminals to conduct connection and preventive tests on various types of sulfur hexafluoride cabinets (applicable to various fully insulated and fully sealed sulfur hexafluoride switch cabinets). However, this method can easily cause the internal insulation of the elbow-type cable head to become dirty and scratched, causing local discharge of the elbow-type cable head and degradation of the insulation performance of the elbow-type cable head. In summary, in the prior art, there are many problems encountered when conducting connection and preventive tests on various types of sulfur hexafluoride cabinets (applicable to various fully insulated and fully sealed sulfur hexafluoride switch cabinets).

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1 to 5 As shown, the utility model provides a new insulation test operating rod, including a test rod body 1, a connecting column 2 is fixedly connected to the left side of the test rod body 1, a clamping column 3 is fixedly connected to the right side of the test rod body 1, a first insulating sleeve 4 is fixedly sleeved on the surface of the test rod body 1, and a second insulating sleeve 5 is fixedly sleeved on the surface of the test rod body 1;

[0025] By clamping the test clamp on the surface of the clamping column 3, and connecting the test rod body 1 to the sulfur hexafluoride circuit breaker cabinet through the connecting column 2, current is conducted through the test rod body 1, and the longer insulation wrapping range of the first insulating sleeve 4 and the second insulating sleeve 5 is solved, which solves the problem of residual glue on the metal parts of the connecting column 2 and the clamping column 3, and avoids the internal insulation from being easily soiled and scratched, causing local discharge of the elbow-type cable head, resulting in a decrease in the insulation performance of the elbow-type cable head, and other problems. The method of using the first insulating sleeve 4 and the second insulating sleeve 5 to extend the insulation protection range not only meets the AC withstand voltage test pressure standard of the "handover and preventive test" of various sulfur hexafluoride cabinet types (applicable to various sulfur hexafluoride fully insulated and fully sealed switch cabinets), but also standardizes the connection wiring between the tested equipment and the test equipment, ensures the firm connection of the connecting wire, prevents the clamping column from falling off, improves work efficiency, and improves the safety factor for people and equipment. It is also easy to load and unload and can be used multiple times.

[0026] Among them, a plurality of insulating rings are fixedly installed on the surface of the second insulating sleeve 5 close to one end of the clamping column 3, and the second insulating sleeve 5 is fixedly sleeved on the side of the surface of the test rod 1 close to the clamping column 3;

[0027] The second insulating sleeve 5 has multiple insulating rings on the surface of one end of the clamping column 3, so that the insulation capacity can be further improved through the insulating rings, and the second insulating sleeve 5 can prevent the test rod 1 from discharging to the outside, thereby causing a large discharge sound.

[0028] The inner cavity of the clamping column 3 is threadedly connected to the threaded rod 6, the inner cavity of the clamping column 3 is movably sleeved with a movable rod 12, the right side of the movable rod 12 is fixedly connected to the fixing frame 10, and the left side of the fixing frame 10 is fixedly connected to the clamping plate 11;

[0029] The threaded rod 6 is threadedly connected to the inner cavity of the clamping column 3, so that the rotation of the threaded rod 6 can drive the fixing frame 10 to move along the axial direction of the threaded rod 6 and the movable rod 12, so that the test clamp can be fixed and limited by the clamping plate 11 to prevent it from deflecting or falling during use, thereby improving its stability during use.

[0030] The threaded rod 6 is fixedly connected to a rotating disk 7 on one side close to the fixing frame 10, and a rotating bin 9 is movably sleeved on the outer surface of the rotating disk 7;

[0031] The rotating disk 7 is movably connected to the inner cavity of the rotating chamber 9, so that the threaded rod 6 can drive the rotating chamber 9 to move when it rotates, and then the movement of the rotating chamber 9 drives the fixing frame 10 to move toward the clamping column 3, so that the clamping plate 11 can contact with the test clamp and fix it.

[0032] The rotating disk 7 is fixedly connected to a rotating ring 8 on a side away from the threaded rod 6, and the fixing frame 10 is a C-shaped frame;

[0033] A rotating ring 8 is fixedly connected to the side of the rotating disk 7 away from the threaded rod 6, so that the staff can rotate the rotating ring 8 to drive the threaded rod 6 to rotate, and then drive the fixing frame 10 to move toward the clamping column 3. Since the fixing frame 10 is a C-shaped frame, the fixing frame 10 can fix the test clamp.

[0034] Among them, the outer surfaces of the rotating ring 8, the rotating chamber 9, the fixing frame 10, and the clamping plate 11 are all fixedly covered with insulating skin;

[0035] The insulating skin on the surface of the rotating ring 8 , the rotating chamber 9 and the fixing frame 10 prevents the current from being conducted through the clamping plate 11 when the clamping plate 11 clamps the test clamp.

[0036] The inner cavity of the clamping column 3 is provided with a thread groove 13, and the threaded rod 6 is threadedly connected to the inner cavity of the thread groove 13;

[0037] By means of the threaded groove 13 in the inner cavity of the clamping column 3, the threaded rod 6 can be threadedly connected to the inner cavity of the threaded groove 13, so that when the staff rotates the rotating ring 8, the threaded rod 6 can be driven to rotate, so that the threaded rod 6 moves toward the inside of the threaded groove 13, and the position of the fixing frame 10 can be adjusted.

[0038] Among them, the side of the clamping plate 11 close to the center of the fixing frame 10 is an inclined surface, and the inclined surface is provided with anti-slip grooves;

[0039] The test clip can be stably clamped by the clamping plate 11 along the inclined surface on one side of the clamping plate 11 close to the center of the fixing frame 10. The anti-slip grooves are provided to increase the friction between the clamping plate 11 and the test clip, thereby preventing the test clip from falling off during the fixing process.

[0040] The working principle and usage process of the present invention are as follows: the connecting column 2 is connected to various types of sulfur hexafluoride cabinets (applicable to various sulfur hexafluoride fully insulated and fully sealed switch cabinets), and then the test clamp is connected to the test equipment. Then, the test clamp is clamped on the surface of the clamping column 3, and then the rotating ring 8 is rotated to drive the threaded rod 6 to rotate. Through the engagement of the threaded rod 6 with the thread groove 13, the threaded rod 6 moves along the thread groove 13 toward the inside of the thread groove 13, and then the rotating disk 7 drives the rotating bin 9 to move, and then drives the fixing frame 10 to move toward the test clamp clamped on the surface of the clamping column 3, and then the clamping plate 11 is used to fix and clamp the test clamp to prevent it from falling off the surface of the clamping column 3;

[0041] Then, through the combination of the first insulating sleeve 4 and the second insulating sleeve 5, the electricity of various types of sulfur hexafluoride cabinets (applicable to various sulfur hexafluoride fully insulated and fully sealed switch cabinets) is connected to the test rod 1, and is transmitted to the test clamp through the clamping column 3, and then transmitted to the test equipment through the test clamp, so that the test equipment displays current and voltage, and then the test is carried out.
