[0002] At present, in order to prevent small animals from short-circuiting, the copper busbars of 10kV high-voltage cabinets are completely wrapped with insulating wrappings. Although this prevents short-circuiting after small animals enter the cabinet, there is no place to hang the grounding wire during power outages. In the absence of effective grounding, it is necessary to manually cut the insulating rubber, hang the grounding wire, and then work can be carried out. After the work is completed, the grounding wire is removed, and then the insulation wrapping is repaired, resulting in a waste of material resources and human resources. At the same time, when cutting and repairing the rubber, there is a risk of sudden power outages without grounding wire protection, resulting in the risk of electric shock death.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0032] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0033] Example 1, reference Figure 1-4 , which is the first embodiment of the present invention, provides a high-voltage cabinet insulation wrapping sleeve that is convenient for testing electricity and grounding. The device includes a copper bar unit 100 and a wrapping sleeve unit 200. By setting the wrapping sleeve unit 200 to cover the exposed part of the copper bar unit 100, such a covering will not be tightly attached to the copper bar 101, which can facilitate the contact between the electrician pen and the copper bar 101 for electricity testing, and can also facilitate the installation of the conductive end of the grounding wire on the copper bar 101, and the grounding wire is stably suspended and grounded without damaging the copper bar unit 100, and can also effectively prevent small animals from entering the high-voltage cabinet and causing the copper bar 101 to short-circuit.

[0034] The copper busbar unit 100 includes a copper busbar 101 arranged in a high-voltage cabinet, an insulating wrapping sleeve 102 arranged on the copper busbar 101, and an insulating wrapping sleeve 2 103 arranged on the copper busbar 101; and the insulating wrapping sleeve 102 and the insulating wrapping sleeve 2 103 are arranged side by side, and the copper busbar 101 is insulated and protected by the insulating wrapping sleeve 102 and the insulating wrapping sleeve 2 103 to prevent small animals from entering the high-voltage cabinet and causing a short circuit in the copper busbar 101.

[0035] The wrapping sleeve unit 200 includes a clamping component 1 201, a clamping component 202 movably arranged on the clamping component 1 201, and a clamping component 3 203 movably arranged on the clamping component 202 and detachable from the clamping component 1 201. The clamping component 1 201 and the clamping component 2 202 work together to clamp the insulating wrapping sleeve 1 102 and the insulating wrapping sleeve 2 103 at one end close to each other, and the insulating wrapping sleeve 1 102 and the insulating wrapping sleeve 2 103 are connected by the wrapping sleeve unit 200. The wrapping sleeve unit 200 is made of insulating material throughout; the clamping component 202 is detachably installed on the clamping component 1 201, and the wrapping sleeve unit 200 can be stably installed on the copper busbar unit 100; the installation of the clamping component 3 203 facilitates multiple inspections required for subsequent long-term use.

[0036] During use, the clamping component 1 201 and the clamping component 2 202 are locked, so that the clamping component 1 201 and the clamping component 2 202 are pressed between the insulating wrapping sleeve 1 102 and the insulating wrapping sleeve 2 103 to cover the exposed part of the copper busbar 101. At the same time, the movable setting of the clamping component 3 203 can facilitate the installation of the conductive end of the grounding wire on the copper busbar 101. Under the limiting action of the clamping component 1 201 and the clamping component 2 202, the installation of the conductive end of the grounding wire is simple and stable, and the grounding wire is convenient to be suspended without damaging the copper busbar unit 100, thereby improving the safety of the operation and meeting the multiple inspection requirements required for long-term work; at the same time, the electrician pen can also be made to contact the copper busbar 101 for use without damaging the copper busbar unit 101; finally, the installation protection of the wrapping sleeve unit 200 can effectively prevent small animals from entering the high-voltage cabinet and causing a short circuit in the copper busbar 101.

[0037] Example 2, reference Figure 1-10 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the conductive end wire clamp of the grounding wire can be inserted between the clamping component 1 201 and the copper bus 101, and can be inserted between the clamping component 202 and the copper bus 101. The clamping component 1 201 and the clamping component 202 are provided to stably limit the wire clamp, so that the clamping installation of the wire clamp is more stable, that is, the hanging of the grounding wire is more convenient and stable; the connecting shell 1 201a will not be directly pressed on the copper bus 101, and the 1.5cm distance between the connecting shell 1 201a and the copper bus 101 can also dissipate heat for the copper bus 101 , avoiding being pressed against the copper bus 101 and causing poor heat dissipation efficiency of the copper bus 101; it is convenient to extend the metal testing part of the test pen through the opening 201f into the connecting shell 201a to contact the copper bus 101 for testing. The opening 201f of this size can also effectively prevent small animals from contacting the copper bus 101. At the same time, even if the copper bus 101 is installed in the corner of the high-voltage cabinet or is blocked by other components, the test pen can be tilted so that the metal testing part can contact the copper bus 101 for testing. At this time, the minimum tilting angle that the test pen can reach is 30 degrees, which can basically adapt to all installation conditions of the copper bus 101.

[0038] Compared with the embodiment 1, further, a gap 104 for electrical testing is reserved between the insulating wrapping sleeve 1 102 and the insulating wrapping sleeve 2 103. The conductive ends of the electrical test pen and the grounding wire are both mounted on the copper busbar 101 at the gap 104, so that electrical connection testing and grounding can be directly performed; when performing the grounding operation, it is only necessary to open the clamping assembly 3 203 to fit the conductive end of the grounding wire into the copper busbar 101 at the gap 104. Since the copper busbar 101 at the gap 104 is protected by the clamping assembly 1 201 and the clamping assembly 2 202, the probability of danger caused by the staff accidentally touching the copper busbar 101 can be effectively reduced during operation, thereby improving the safety of the operation.

[0039] Preferably, the clamping assembly 201 comprises a connecting shell 201a, an inclined shell 201b disposed at the upper and lower ends of the connecting shell 201a, a clamping shell 201c disposed on the inclined shell 201b, a locking bolt 201d disposed on the clamping shell 201c, and a protrusion 201e disposed on the connecting shell 201a. Two clamping shells 201c are provided, and the two clamping shells 201c are respectively connected to the ends of the two inclined shells 201b that are away from each other. The two clamping shells 201c are both distributed parallel to the connecting shell 201a. The two clamping shells 201c are respectively pressed on the ends of the insulating wrapping sleeve 102 and the insulating wrapping sleeve 2 103 that are close to each other. Both ends of each clamping shell 201c are provided with rounded corners 2 for pressing the insulating wrapping sleeve 102 and the insulating wrapping sleeve 2 103.

[0040] Furthermore, the projection of the connection shell 1 201a along the X direction is L-shaped, and the connection shell 1 201a is provided with a fillet 1 at the bend. The inclined shell 1 201b is fully matched with the connection shell 1 201a; the connection shell 1 201a is set to be L-shaped and will not be directly pressed on the copper bus 101. There is an installation gap between the connection shell 1 201a and the copper bus 101, which is also convenient for heat dissipation of the copper bus 101.

[0041] Furthermore, the projection length of the connection shell 201a along the Y direction is 1.5 cm. The thickness of the connection shell 201a is negligible, that is, the vertical distance between the inner wall of the connection shell 201a and the copper bus 101 is 1.5 cm; since the electrician's pen needs to pass through the connection shell 201a and contact the copper bus 101 during the inspection, and the length of the metal electrician's pen on the existing electrician's pen is 4 cm, the vertical distance of 1.5 cm is enough for the metal electrician's pen on the electrician's pen to contact the copper bus 101; at the same time, the conductive end of the existing grounding wire is a wire clamp structure, such as Fig. 9 and Fig.10As shown, the thickness of the wire clamp is slightly less than 1.5 cm. Therefore, the conductive end wire clamp of the grounding wire can be inserted between the clamping component 1 201 and the copper bus 101, and can be inserted between the clamping component 202 and the copper bus 101. The clamping component 1 201 and the clamping component 2 202 are provided to stably limit the wire clamp, so that the clamping installation of the wire clamp is more stable, that is, the hanging of the grounding wire is more convenient and stable; finally, the connecting shell 1 201a will not be directly pressed on the copper bus 101, and the 1.5 cm distance between the connecting shell 1 201a and the copper bus 101 can also dissipate heat for the copper bus 101, avoiding poor heat dissipation efficiency of the copper bus 101 caused by being pressed on the copper bus 101.

[0042] In particular, the connection shell 1 201a is provided with an opening 201f for connecting electricity. By providing the opening 201f, the electrician pen can be in contact with the copper busbar 101 for electric testing without damaging the copper busbar unit 100. At the same time, the opening 201f can also facilitate the conductive end of the grounding wire to pass through the connection shell 1 201a, and will not block the installation of the conductive end of the grounding wire, so that the installation of the conductive end of the grounding wire is limited by the connection shell 1 201a, the clamping component 2 202, and the opening 201f at the same time, so that the installation of the conductive end of the grounding wire is more stable and the suspension of the grounding wire is more convenient; by directly testing the electricity through the opening 201f, small animals cannot directly contact the copper busbar 101, avoiding the short circuit of the copper busbar 101 caused by small animals entering the high-voltage cabinet.

[0043] Preferably, the projection shape of the opening 201f along the Z direction is a rectangle 201g, and an arc 201h is provided in the width direction of the rectangle 201g. The length of the rectangle 201g is 2 cm, the width is 1.5 cm, and the arc 201h has a diameter of 1.5 cm, so that the metal test part of the test pen can be extended into the connection shell 1 201a through the opening 201f to contact the copper bus 101 for testing. The opening 201f of this size can also effectively prevent small animals from contacting the copper bus 101. At the same time, even if the copper bus 101 is installed in the corner of the high-voltage cabinet or is blocked by other components, the test pen can be tilted so that the metal test part can contact the copper bus 101 for testing. At this time, the minimum tilting angle that the test pen can reach is 30 degrees, which can basically adapt to all installation conditions of the copper bus 101.

[0044] The remaining structures are the same as those of Example 1.

[0045] Example 3, reference Figure 1-10, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the conductive end of the grounding wire is inserted into the fixed frame 203d, and the limiting shell 203c can be rotated to a position that cooperates with the protrusion 201e by rotating the conductive end of the grounding wire. The through hole 203f and the protrusion 201e are clamped together to limit the clamping component three 203 as a whole. The clamping component one 201, the clamping component two 202 and the clamping component three 203 together form a wrapping sleeve unit 200, which shields and protects the exposed part of the copper bus 101, thereby preventing small animals from entering the high-voltage cabinet and causing a short circuit of the copper bus 101; the entire operation process can be achieved through the mutual contact between the insulating materials, which reduces the risk of accidental electric shock by the staff and improves the safety of the operation.

[0046] Compared to Example 2, further, the clamping assembly 202 includes a connecting shell 202a movably arranged on the connecting shell 1 201a, an inclined shell 202b arranged at both ends of the connecting shell 202a, a clamping shell 202c arranged on the inclined shell 202b, and a fixing ear 202d arranged on the clamping shell 202c. The connecting shell 202a is rotatably set on the connecting shell 1 201a through a hinge 1; the connecting shell 202a has the same structure as the connecting shell 1 201a, the tilting shell 202b has the same structure as the tilting shell 1 201b, the clamping shell 202c has the same structure as the clamping shell 1 201c, and the fixing ear 202d cooperates with the locking bolt 201d to stably limit the clamping component 1 201 and the clamping component 2 202, so that the clamping component 1 201 and the clamping component 2 202 are stably clamped on the insulating wrapping sleeve 1 102 and the insulating wrapping sleeve 2 103 to form the insulation of the copper bus 101 as a whole.

[0047] Preferably, the clamping assembly three 203 includes a sealing shell 203a movably arranged on the connecting shell two 202a, a sealing cover 203b arranged at the upper and lower ends of the sealing shell 203a, a limiting shell 203c arranged on the sealing shell 203a and cooperating with the protrusion 201e, and a fixing frame 203d arranged on the limiting shell 203c. The sealing cover 203b is provided with a making way opening 203e for making way for the clamping shell 1 201c and the clamping shell 2 202c, and the limiting shell 203c is provided with a through hole 203f for clamping the protrusion 201e; the conductive end of the grounding wire is inserted into the fixed frame 203d, and the limiting shell 203c can be rotated to a position matched with the protrusion 201e by rotating the conductive end of the grounding wire, and the clamping assembly 3 203 is limited as a whole by the matching clamping of the through hole 203f and the protrusion 201e. The clamping assembly 1 201, the clamping assembly 202 and the clamping assembly 3 203 together form a wrapping sleeve unit 200, which shields and protects the exposed part of the copper busbar 101, thereby preventing the copper busbar 101 from short-circuiting due to small animals entering the high-voltage cabinet.

[0048] Furthermore, the fixing frame 203d is made of insulating rubber material. By setting it to insulating rubber material, the fixing frame 203d will not be in an open state when not in use, which can effectively prevent small animals from scratching the fixing frame 203d during crawling, and reduce the loose state of the fixing of the limiting shell 203c.

[0049] The remaining structure is the same as that of Example 2.
