Description

Technical Field

[0001] This invention belongs to the field of power maintenance equipment technology, specifically relating to a high-voltage connector live fastening and shunt device. Background Technology

[0002] High-voltage substation connectors and their connecting wires are exposed to the elements for extended periods. Under prolonged operation, they are subject to mechanical vibration, wind swaying, and the heating effect of electric current. This often leads to loosening of the connection points, resulting in problems such as displacement, wear, oxidation, and corrosion, as well as poor contact and high contact resistance. Ultimately, this can cause the connection points of the high-voltage connectors and wires to overheat and burn out.

[0003] Currently, the power industry primarily uses a power outage approach when inspecting and repairing overheated high-voltage joints, conductors, and their connections. This involves shutting off power to the high-voltage joint and its connecting conductors with overheating defects, tightening the joint and conductors, or replacing them directly, and then restoring power. This method results in a long power outage time. Existing live-line maintenance methods use long insulated operating rods to lift and repair live-line maintenance devices. However, since these devices mostly perform parallel current shunting on the high-voltage joint or conductor body, they cannot address loosening issues at the joint and conductor connections. Furthermore, they do not consider the safety and convenience of personnel holding insulated rods to tighten the connections under different angles between the conductor and the high-voltage joint. There is no readily available live-line tightening and current shunting device that facilitates the repair of overheating defects at the high-voltage joint and its connecting conductor connections. Summary of the Invention

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] A high-voltage connector live fastening and shunt device (hereinafter referred to as the fastening and shunt device) is mainly composed of a first clamp structure 10, a second clamp structure 20, and an overlapping structure 30. The first clamp structure 10 and the second clamp structure 20 have the same construction. In the following description, unless otherwise specified, the clamp structure can refer to either the first clamp structure 10 or the second clamp structure 20. In some embodiments, the first clamp structure 10 and the second clamp structure 20 are both made of high-strength, high-conductivity, corrosion-resistant, and lightweight materials. The first clamp structure 10 and the second clamp structure 20 are connected by the overlapping structure 30 to assemble the fastening and shunt device. The relative position of the first clamp structure 10 and the second clamp structure 20 can be adjusted based on the overlapping structure 30 so that the first clamp structure 10 and the second clamp structure 20 can be adjusted as needed during maintenance and connected to the maintenance position on the high-voltage connector to complete the maintenance work.

[0042] Reference Figure 1 Using the coordinate system in the figure as a reference, the positions are described, and the X, Y, and Z axes in the figure are respectively labeled as the first direction, the second direction, and the third direction, i.e., the first direction, the second direction, and the third direction are perpendicular to each other. Specifically, the clamp structure includes a base member 100, a clamping member 103, and a locking structure 50. The base member 100 has a notch structure 104, and the clamping member 103 is disposed in the notch structure 104 and configured to move linearly along the third direction. Correspondingly, the locking structure 50 is assembled on the base member 100 and configured to adjust the position of the clamping member 103 in the third direction and to hold the clamping member 103 in a set position, so as to cooperate with the base member 100 to clamp subsequent high-voltage connectors or wires, thereby completing the maintenance work. Figure 1Continuing with the description of the base member 100, the base member 100 has a first mounting surface 101 and a second mounting surface 102. The first mounting surface 101 is configured as at least one end face of the base member 100 in a first direction. In some examples, both end faces of the base member 100 in the first direction are configured as part of the first mounting surface 101. Correspondingly, the second mounting surface 102 is configured as an end face of the base member 100 in a second direction. That is, the first mounting surface 101 and the second mounting surface 102 are perpendicularly arranged. In some embodiments, both the first mounting surface 101 and the second mounting surface 102 are configured as the assembly surface of the overlapping structure 30. That is, the overlapping structure 30 is connected to the base member 100 at the location of the first mounting surface 101 or the second mounting surface 102. In some examples, refer to... Figure 5 The second mounting surface 102 is provided with threaded holes for subsequent assembly of the overlapping structure 30.

[0043] Reference Figure 2 In some embodiments, the above-mentioned overlapping structure 30 includes a first overlapping member 300 and a second overlapping member 301. One end (hereinafter referred to as the first end) of the first overlapping member 300 and the second overlapping member 301 is rotatably connected, for example, by means of a pin. The other end (hereinafter referred to as the second end) is respectively connected to one of the base members 100 of the first clamping structure 10 and the second clamping structure 20. Based on the rotatable connection of the first overlapping member 300 and the second overlapping member 301 at the first end position, the relative position adjustment of the second ends of the first overlapping member 300 and the second overlapping member 301 can be realized, thereby realizing the position adjustment of the first clamping structure 10 and the second clamping structure 20. In some examples, the second end of the first overlapping member 300 is fixed to the first mounting surface 101 or the second mounting surface 102 of the base member 100 of the first clamping member, and the second end of the second overlapping member 301 is fixed to the first mounting surface 101 or the second mounting surface 102 of the base member 100 of the second clamping member.

[0044] In some embodiments, refer to Figure 3The first overlapping member 300 and the second overlapping member 301 are both configured as triangular plates. In the following description, unless otherwise specified, the overlapping member can refer to either the first overlapping member 300 or the second overlapping member 301. The overlapping members have overlapping surfaces 302 in the width direction for cooperating with the first mounting surface 101 or the second mounting surface 102 on the base member 100 to realize the assembly of the base member 100 and the overlapping member, realizing three states of the first clamping structure 10 and the second clamping structure 20: parallel arrangement in the same direction along the second direction (overlapping surfaces 302 are all connected to the first mounting surface 101 of the clamping structure), parallel arrangement in opposite directions along the first direction (overlapping surfaces 302 are all connected to the second mounting surface 102 of the clamp), and vertical arrangement (overlapping surfaces 302 are respectively connected to the first mounting surface 101 and the second mounting surface 102 of the clamp).

[0045] In some embodiments, refer to Figure 1 The base component 100 includes a main body 100a, a first ear 100b, and a second ear 100c. The main body 100a extends along a third direction. One end of the first ear 100b and the second ear 100c are respectively connected to the two ends of the main body 100a, and the other end extends along a second direction. The main body 100a, the first ear 100b, and the second ear 100c together form the notch structure 104. Correspondingly, the clamping component 103 extends along the second direction within the notch structure 104 and works together with the first ear 100b to clamp the subsequent high-voltage connector or wire. That is, the opposing surfaces of the clamping component 103 and the first ear 100b constitute the clamping surface of the high-voltage connector or wire. In some embodiments, the clamping surfaces of the clamping component 103 and the first ear 100b are provided with arc-shaped grooves to achieve stable clamping of the wire. In some embodiments, the clamping component 103 has a "convex" shaped cross section in the second direction.

[0046] In some embodiments, the base member 100 is provided with a reinforcing rib structure 105 on the first mounting surface 101 to improve the overall strength of the base member 100. For example, the reinforcing rib structure 105 extends along the contour of the main body portion 100a, and the extension range covers the arc bend between the first ear portion 100b and the second ear portion 100c and the main body portion 100a.

[0047] In some embodiments, refer to Figure 1The aforementioned locking structure 50 includes a screw member 500. One end of the screw member 500 is disposed outside the notch structure 104 and fitted with a seat member 503. The other end extends along a third direction through the second ear 100c and into the notch structure 104. The screw member 500 and the second ear 100c are threadedly connected. During operation, a rotational driving force is applied to the screw member 500 through the seat member 503. The screw member 500 rotates while moving linearly along a third direction to achieve clamping. The holding member 103 is adjusted in a third-direction upward position. In some embodiments, the locking structure 50 further includes a rod member 504 made of a high-strength material, such as a high-strength lightweight metal. The seat member 503 has a through hole for inserting the rod member 504. During operation, the rod member 504 can be inserted into the groove in the seat member 503, and a rotational driving force is applied to the screw member 500 based on the rod member 504, thereby improving the ease of operation of the locking structure 50 and enhancing operational safety. In some embodiments, the screw member 500 is configured as a hollow structure. The hollow cavity can be a cylinder or a polygonal column to reduce the overall weight of the fastening diverter and facilitate the operation of the fastening device. In some embodiments, one end of the screw member 500 extending into the notch structure 104 forms a radially outwardly extending flange portion 500a. Correspondingly, the clamping member 103 forms a through hole for inserting the flange portion 500a of the screw member 500. The groove into which the screw member 500 is inserted is provided, and the clamping member 103 is provided with a limiting structure for limiting the flange portion 500a after one end of the screw member 500 enters the groove of the clamping member 103, so as to prevent the screw member 500 from sliding out of the groove of the clamping member 103. For example, a hole for inserting a pin is formed on the end face of the clamping member 103, and the hole extends inward to the groove position so that the pin can be inserted into the groove and limit the flange portion 500a of the screw member 500.

[0048] In some embodiments, the locking structure 50 further includes an elastic member 501 (e.g., a damping spring), which is disposed on the periphery of the screw member 500, and its two ends are respectively connected to the clamping member 103 and the second ear 100c. Based on the elastic force of the elastic member 501, the stability of the clamping member 103 during clamping is improved, and the vibration and impact of the screw on the clamping member 103 are mitigated. In some embodiments, the locking structure 50 further includes a latch member 502, which is disposed in the notch structure 1. 04 is fitted onto the screw member 500. In some embodiments, the aforementioned clip member 502 has a through hole for the screw member 500 to pass through, and has a base portion 502a and an extension portion 502b, wherein the end face of the base portion 502a contacts one end of the elastic member 501, and the extension portion 502b extends in a third direction and forms a gap between the screw member 500 and the elastic member 501. Correspondingly, the aforementioned clamping member 103 has a circular groove 505 at the contact position with the elastic member 501, and the size of the circular groove 505 is adapted to the elastic member 501. The elastic member 501 is partially inserted into the circular groove 505. Based on the cooperation between the clip member 502 and the circular groove 505, the elastic member 501 remains stable during the movement of the clamping member 103, and the friction between the elastic member 501 and the screw member 500 is reduced. This ensures that during the initial installation phase, the resistance experienced by the entire screw member 500 mainly comes from the friction between the neck of the screw member 500 and the clamping structure, so that the operator feels some frictional resistance but the overall resistance is not significant. Specifically, during the middle stage of installation, the flange portion 500a of the screw member 500... Separated from the clamping member 103, the rotation of the screw member 500 has almost no frictional resistance, making the operator feel that the operation is effortless. However, in the later stages of installation, after the flange end 500a of the screw member 500 contacts the groove end face in the clamping member 103, it is subjected to great friction, making the operator feel great operating resistance. Therefore, based on the combination of the card holder member 502, the elastic member 501, the clamping member 103, and the screw member 500 to form a tactile feedback system, the installation progress can be fed back to the operator through stepped resistance, making up for the deficiency that the installation process cannot be effectively observed visually.

[0049] In some embodiments, both the first overlapping member 300 and the second overlapping member 301 are made of high-strength, high-toughness insulating material. Correspondingly, the overlapping structure 30 further includes at least one flow line 305, which is configured as a conductive copper wire and is used to connect the first clamp structure 10 and the second clamp structure 20 to achieve an electrical connection between the first clamp structure 10 and the second clamp structure 20. (Refer to...) Figure 1 and 3In some embodiments, the base component 100 of the clamp structure is provided with at least one through hole 304 on both the first mounting surface 101 and the second mounting surface 102, for fixing the flow line 305 on the clamp structure.

[0050] Reference Figure 4 The diagram shows the structure of a high-voltage connector. As can be seen from the diagram, the high-voltage connector structure includes a high-voltage connector 13 and a high-voltage wire 14. The connection position between the high-voltage connector 13 and the high-voltage wire 14 is provided with a connection part 15, which is mainly composed of a crimping tube. Based on this diagram, the usage process of the above-mentioned fastening device will be explained. Specifically, the usage steps of the above-mentioned fastening device are as follows:

[0051] Step 1: Based on the defective working condition of the connection part 15 between the high voltage connector 13 and the conductor 14, adjust the relative position of the first clamping structure 10 and the second clamping structure 20 by the relative rotation of the first overlapping member 300 and the second overlapping member 301, and by the combination of the overlapping surface 302 with the first clamping structure 10 and the second clamping structure 20 on the first assembly surface and the second assembly surface, so that the high voltage connector 13 and the high voltage conductor 14 are respectively located between the clamping member 103 and the first ear 100b in the first clamping structure 10 and the second clamping structure 20.

[0052] Step Two: Stand on the insulating mat, wear insulating gloves, and use the insulating rod connecting rod component 504 or base component 503 provided by the maintenance personnel to operate the locking structure 50, so that the screw component 500 rotates, thereby driving the clamping component 103 to move. This, in conjunction with the first ear 100b, clamps the high-voltage connector 13 and the high-voltage wire 14, thereby fixing the first clamping structure 10 and the second clamping structure 20 to the high-voltage connector 13 and the high-voltage wire 14 respectively, and forming a circuit through the first clamping structure 10, the second clamping structure 20 and the flow line 305; and forming a solidified body through the first clamping structure 10, the second clamping structure 20 and the first overlapping component 300 and the second overlapping component 301.

[0053] Step 3: After the maintenance work is completed based on the fastening device, the insulating rod can be pulled to separate from the rod component 504 or the base component 503 to retrieve the insulating rod brought by the maintenance personnel. The fastening diversion device is left at the defect for continuous defect elimination.
