[0030] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0032] When used herein, the singular forms "a", "an" and " / the" may also include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" and the like specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof. At the same time, in this specification, the term "and / or" includes any and all combinations of the relevant listed items.

[0033] It should be noted that in the power system, the current loop terminal of the substation is a key component for realizing current signal transmission. When inspecting or testing the current loop, in order to ensure the safety of personnel and the normal operation of equipment, the current loop needs to be reliably short-circuited.

[0034] However, in conventional substation current loop terminals, a single current loop terminal is usually used to simultaneously connect multiple conductors, which results in that when a single conductor is short-circuited, the single current loop terminal needs to be short-circuited through a short-circuit hole, which will short-circuit multiple conductors connected simultaneously, affecting the connection quality of the remaining conductors, resulting in poor short-circuit quality of the substation current loop terminal, and affecting the stability and reliability of the substation current loop terminal. In addition, for the existing double-input and double-output terminals, although the number of conductors connected to each current loop terminal can be reduced to improve the independence of each connected conductor and improve the stability and reliability of the current loop terminal. However, the existing double-input and double-output terminals are not provided with short-circuit holes, which results in the inability of the existing double-input and double-output terminals to achieve live short-circuiting of the conductors.

[0035] The operation difficulty during the short-circuiting process is usually greater, and the short-circuiting effect is poor, which further increases the safety risks during the short-circuiting process.

[0036] In view of this, it is an urgent problem to be solved to propose a current loop terminal short-circuiting device that can reduce the difficulty of short-circuiting the current loop terminal of the substation and improve the short-circuiting effect.

[0037] FIG1 is a schematic structural diagram of a substation current loop terminal short-circuit device provided in an embodiment of the present application. As shown in FIG1 , in a first aspect of an embodiment of the present application, a substation current loop terminal short-circuit device is provided, comprising: two conductive brackets 100 disposed at intervals, a plurality of conductive pillars 200 and a sliding conductive structure 300. The conductive support 100 includes a first conductive support 110 and a second conductive support 120; the conductive column 200 is movably connected to the conductive support 100, and the conductive column 200 at least penetrates part of the conductive support 100, wherein at least one conductive support 100 corresponds to at least two conductive columns 200; the sliding conductive structure 300 is located between the conductive supports 100, wherein when the sliding conductive structure 300 is in a fixed state, the two conductive supports 100 have a first state and a second state, wherein in the first state, the sliding conductive structure 300 is spaced apart from at least one conductive support 100, so that the first conductive support 110 and the second conductive support 120 are insulated, and in the second state, the two ends of the sliding conductive structure 300 are respectively connected to the first conductive support 110 and the second conductive support 120, so that the first conductive support 110 and the second conductive support 120 are electrically connected; wherein a short-circuit hole 101 is provided in the conductive support 100, and the short-circuit hole 101 is used to connect a short-circuit wire.

[0038] Exemplarily, the material of the conductive support 100 may include a metal material. In the direction in which the first conductive support 110 points to the second conductive support 120, the size of the sliding conductive structure 300 is less than or equal to the distance between the first conductive support 110 and the second conductive support 120. In the case in which the size of the sliding conductive structure 300 is greater than the distance between the first conductive support 110 and the second conductive support 120 in the direction in which the first conductive support 110 points to the second conductive support 120, the size of the sliding conductive structure 300 is less than or equal to the sum of the size of the first conductive support 110 and the distance between the first conductive support 110 and the second conductive support 120, wherein in the direction in which the first conductive support 110 points to the second conductive support 120, the size of the first conductive support 110 is greater than the size of the second conductive support 120.

[0039] For example, one conductive support 100 may correspond to one conductive pillar 200, and the other conductive support 100 may correspond to at least two conductive pillars 200. Wherein, in the case where both conductive supports 100 correspond to multiple conductive pillars 200, the number of conductive pillars 200 corresponding to different conductive supports 100 may be different.

[0040] For example, when the sliding conductive structure 300 is in a sliding state, the position of the sliding conductive structure 300 can be adjusted. The material of the sliding conductive structure 300 can include a metal material.

[0041] It should be noted that in a conventional short-circuit device for a current loop terminal of a substation, the tail shorting piece usually occupies the shorting hole 101, thereby affecting the access of the shorting wire. Therefore, in the short-circuit device for a current loop terminal of a substation provided in an embodiment of the present application, the tail shorting piece can be combined with a movable bracket so that the shorting hole 101 can be switched between a state of contacting the tail shorting piece and a state of contacting the shorting wire according to the shorting requirement.

[0042] It should be noted that one conductive post 200 in the substation current loop terminal short-circuiting device provided in the embodiment of the present application can be used to connect a wire to avoid the need to crimp different wires, which affects the connection quality of the wires.

[0043] The substation current loop terminal short-circuit device provided in the embodiment of the present application is provided with two conductive brackets 100 arranged at intervals, so that the first conductive bracket 110 and the second conductive bracket 120 are insulated from each other, and one conductive bracket 100 is provided corresponding to at least two movably connected conductive posts 200, so that a group of conductive brackets 100 can be connected to at least three wires at the same time, thereby increasing the number of wires connected to a group of conductive brackets 100. By moving the position of the sliding conductive structure 300, the connection relationship between the first conductive bracket 110 and the second conductive bracket 12 can be changed. So that when the first conductive bracket 110 and the second conductive bracket 120 are in the first state, the short-circuit wire is connected by the short-circuit hole 101 provided through the conductive bracket 100 to achieve the short-circuit of the connected wire. Therefore, the live short-circuit of the wire can be achieved by adjusting the position of the sliding conductive structure 300 and the access of the short-circuit wire, which can reduce the difficulty of short-circuiting and improve the short-circuit effect, thereby further reducing the safety risk during the short-circuit process.

[0044] As shown in FIG. 1 , in some feasible implementations, in a first direction X, a size of the first conductive support 110 is larger than a size of the second conductive support 120 , wherein the first direction X is a direction from the first conductive support 110 to the second conductive support 120 .

[0045] It should be noted that, by setting the size of the first conductive bracket 110 in the first direction X to be larger than the size of the second conductive bracket 120 in the first direction X, when the fixed sliding conductive structure 300 is in a fixed state and the two conductive brackets 100 are in the first state, at least a portion of the sliding conductive structure 300 is accommodated by the first conductive bracket 110.

[0046] The substation current loop terminal short-circuit device provided in the embodiment of the present application can facilitate switching the connection state of the two conductive brackets 100 to the first state by setting the size of the first conductive bracket 110 in the first direction X to be larger than the size of the second conductive bracket 120 in the first direction X, and can also facilitate reducing the distance between the first conductive bracket 110 and the second conductive bracket 120. Therefore, the volume of the second conductive bracket 120 can be reduced, and the volume of the substation current loop terminal short-circuit device can be further reduced, thereby improving the short-circuit effect.

[0047] As shown in Figure 1, in some feasible embodiments, the sliding conductive structure 300 includes two conductive rails 310 spaced apart in the second direction Y, and the conductive rails 310 slide along the first direction X, wherein the first direction X is the direction from the first conductive support 110 to the second conductive support 120, and the direction in which the conductive column 200 passes through the conductive support 100 is the second direction Y.

[0048] The substation current loop terminal short-circuiting device provided in the embodiment of the present application can reduce the difficulty of adjusting the position of the sliding conductive structure 300 by setting the sliding conductive structure 300 to include two conductive slide rails 310 spaced apart in the second direction Y, and further improve the switching efficiency of the electrical connection state between the first conductive bracket 110 and the second conductive bracket 120, and reduce the difficulty of switching the electrical connection state. Thereby, the difficulty of short-circuiting the substation current loop terminal can be further reduced, the short-circuiting efficiency can be improved, the short-circuiting effect can be improved, and the safety risk during the short-circuiting process can be reduced.

[0049] As shown in Figure 1, in some feasible embodiments, the sliding conductive structure 300 also includes a fastening structure 320, which is connected to two conductive rails 310. When the fastening structure 320 is in a loose state, the conductive rails 310 slide along the first direction X relative to the conductive bracket 100. When the fastening structure 320 is in a fastened state, the conductive rails 310 and the conductive bracket 100 are relatively stationary.

[0050] Exemplarily, the fastening structure 320 may include a fastening screw.

[0051] The substation current loop terminal short-circuiting device provided in the embodiment of the present application can reduce the difficulty of switching between the tightened state and the loosened state of the conductive slide rail 310 by setting a fastening structure 320, speed up the switching efficiency, and further reduce the difficulty of short-circuiting the substation current loop terminal, improve the short-circuiting efficiency, improve the short-circuiting effect, and reduce the safety risks during the short-circuiting process.

[0052] As shown in FIG. 1 , in some feasible implementations, the short-circuit holes 101 include two, and the two short-circuit holes 101 are respectively disposed in the first conductive support 110 and the second conductive support 120 .

[0053] The substation current loop terminal short-circuiting device provided in the embodiment of the present application can realize separate short-circuiting of the wire electrically connected to the first conductive bracket 110 and the wire electrically connected to the second conductive bracket 120 by respectively setting a short-circuiting hole 101 in the first conductive bracket 110 and the second conductive bracket 120, thereby further improving the short-circuiting efficiency of the substation current loop terminal and further improving the safety of the short-circuiting device of the substation current loop terminal.

[0054] In some feasible implementations, the shorting hole 101 includes a threaded shorting hole 101 .

[0055] Exemplarily, the short-circuit wire can be a conventional short-circuit wire, an expansion head short-circuit wire, a self-locking short-circuit wire, etc., wherein the conventional short-circuit wire and the expansion short-circuit wire have poor access effects, poor fastening effects with the short-circuit hole 101, and are prone to falling off. The self-locking short-circuit wire is prone to damage the short-circuit hole 101. Therefore, the short-circuit hole 101 in the substation current loop terminal short-circuit device provided in the embodiment of the present application can be used to access a short-circuit wire with a wire ear head.

[0056] The substation current loop terminal short-circuiting device provided in the embodiment of the present application can improve the tightness of the short-circuiting wire connection in the short-circuiting hole 101 and prevent the short-circuiting wire from loosening by setting the short-circuiting hole 101 including a threaded short-circuiting hole 101, thereby further improving the short-circuiting quality of the substation current loop terminal device, improving the safety in the short-circuiting state, and reducing safety risks.

[0057] In some feasible implementations, the circumferential surface of the conductive pillar 200 includes a threaded surface, and the portion of the conductive support 100 that contacts the conductive pillar 200 has a threaded surface that matches the conductive pillar 200 .

[0058] Exemplarily, the conductive pillar 200 may include a fastening screw.

[0059] For example, the wire can be inserted between the conductive post 200 and the corresponding conductive bracket 100, so that by rotating the conductive post 200, the thread on the circumferential surface of the conductive post 200 can be matched with the thread inside the conductive bracket 100. When the conductive post 200 is tightened in the direction close to the conductive bracket 100, the conductive post 200 can apply pressure to the wire to fix the wire so that the wire contacts the metal bracket 100. When the conductive post 200 is loosened in the direction away from the conductive bracket 100, the connection between the wire and the metal bracket 100 can be released.

[0060] The substation current loop terminal short-circuit device provided in the embodiment of the present application can reduce the difficulty of wire access, improve the wire access quality, and improve the reliability, stability and safety of the substation current loop terminal short-circuit device by setting the circumferential surface of the conductive column 200 to include a threaded surface, and setting the portion of the conductive bracket 100 in contact with the conductive column 200 to have a threaded surface that matches the conductive column 200.

[0061] As shown in FIG. 1 , in some feasible implementations, a conductive support 100 is connected to two conductive pillars 200 , and the two conductive pillars 200 are staggered in the second direction Y, wherein the extension direction of the conductive pillars 200 is the second direction Y.

[0062] The substation current loop terminal short-circuit device provided in the embodiment of the present application can make the first conductive support 110 and the second conductive support 120 both have double-layer terminals by staggering the two conductive posts 200 connected to one conductive support 100 in the extension direction of the conductive posts 200, which can further reduce the size of the conductive support 100, reduce the volume of the substation current loop terminal short-circuit device, and reduce the preparation cost of the substation current loop terminal short-circuit device. At the same time, it can facilitate the isolation of the fault point in the current loop.

[0063] Fig. 2 is a schematic structural diagram of a substation current loop terminal short-circuiting device provided in an embodiment of the present application. As shown in Fig. 2, a second aspect of the embodiment of the present application provides a substation current loop terminal short-circuiting device, comprising: at least two substation current loop terminal short-circuiting devices 1000 as described in any one of the first aspects above.

[0064] The substation current loop terminal short-circuiting device provided in the embodiment of the present application is provided with two conductive brackets 100 arranged at intervals, so that the first conductive bracket 110 and the second conductive bracket 120 are insulated from each other, and one conductive bracket 100 is provided corresponding to at least two movably connected conductive posts 200, so that a group of conductive brackets 100 can be connected to at least three wires at the same time, thereby increasing the number of wires connected to a group of conductive brackets 100. By moving the position of the sliding conductive structure 300, the connection relationship between the first conductive bracket 110 and the second conductive bracket 12 can be changed. So that when the first conductive bracket 110 and the second conductive bracket 120 are in the first state, the short-circuiting wire is connected by the short-circuiting hole 101 provided through the conductive bracket 100 to achieve the short-circuiting of the connected wire. Therefore, the live short-circuiting of the wire can be achieved by adjusting the position of the sliding conductive structure 300 and the access of the short-circuiting wire, which can reduce the difficulty of short-circuiting and improve the short-circuiting effect, thereby further reducing the safety risk during the short-circuiting process.

[0065] FIG3 is a schematic flow chart of a method for short-circuiting a substation current loop terminal provided in an embodiment of the present application. As shown in FIG3, a third aspect of an embodiment of the present application provides a method for short-circuiting a substation current loop terminal, which is applied to a substation current loop terminal short-circuiting device as described in any one of the first aspects above, including:

[0066] Step S110 , fixing the wire through the conductive column 200 so that the wire is connected to the substation current loop terminal short-circuit device 1000 .

[0067] For example, the connection state between the conductive column 200 and the corresponding conductive support 100 can be adjusted to fix or loosen the conductive wire, so as to achieve connection and disconnection of the conductive wire in the substation current loop terminal short-circuit device 1000.

[0068] Step S120 , moving the sliding conductive structure 300 to a first state so that the first conductive support 110 and the second conductive support 120 are insulated from each other.

[0069] For example, when it is necessary to disconnect the electrical connection between the first conductive support 110 and the second conductive support 120, the sliding conductive structure 300 can be switched to an active state first, so as to control the sliding conductive structure 300 to slide in the direction from the first conductive support 110 to the second conductive support 120. When the sliding conductive structure 300 is disconnected from at least one of the first conductive support 110 and the second conductive support 120, the relative positional relationship between the sliding conductive structure 300 and the conductive support 100 can be fixed, so that the first conductive support 110 and the second conductive support 120 are insulated from each other.

[0070] Step S130 , setting a short-circuit wire in the short-circuit hole 101 .

[0071] The transformer substation current loop terminal short-circuiting method provided by the embodiment of the present application is to provide two conductive brackets 100 arranged at intervals, so that the first conductive bracket 110 and the second conductive bracket 120 are insulated from each other, and one conductive bracket 100 is provided corresponding to at least two movably connected conductive posts 200, so that a group of conductive brackets 100 can be connected to at least three wires at the same time, thereby increasing the number of wires connected to a group of conductive brackets 100. By moving the position of the sliding conductive structure 300, the connection relationship between the first conductive bracket 110 and the second conductive bracket 12 can be changed. So that when the first conductive bracket 110 and the second conductive bracket 120 are in the first state, the short-circuiting wire is connected by the short-circuiting hole 101 provided through the conductive bracket 100 to achieve the short-circuiting of the connected wire. Therefore, the live short-circuiting of the wire can be achieved by adjusting the position of the sliding conductive structure 300 and the access of the short-circuiting wire, which can reduce the difficulty of short-circuiting and improve the short-circuiting effect, thereby further reducing the safety risk during the short-circuiting process.
