If the electrical equipment in the converter station leaks electricity, grounding can introduce the current into the earth to ensure the safety of people when they touch the equipment casing. At the same time, it can protect the equipment. When overvoltage occurs, the charge can be introduced into the earth to prevent the insulation of the equipment from being broken down. From an operation perspective, it can provide a stable reference potential for the control and protection system, reduce electromagnetic interference, and assist in fault protection and positioning to ensure the reliable operation of the converter station.

[0003] The patent application with application number CN201721273276.2 discloses a grounding device in a converter station and a DC transmission system, which relates to the field of high-voltage DC transmission. It is invented to solve the problem of excessive current passing through the loop of the grounding device in the converter station connected to the common grounding electrode during the process of changing the operating state of the DC transmission system in which the converter station is located when there is a large ground current entering the common grounding electrode.

[0012] According to the above technical solution, the inner wall of the extrusion block is rotatably connected to the second rotating rod via a rotating shaft, and the outer wall of the second rotating rod on the side away from the extrusion block is rotatably connected to the second mounting rod via a rotating shaft, the bottom of the second mounting rod is rotatably connected to the fixed block, and the outer surface of the second mounting rod is provided with a mounting groove. When the extrusion block is pressed, the extrusion block will push the second mounting rod through the second rotating rod under the action of pressure, causing the second mounting rod to flip over, and the outer surface of the second mounting rod is provided with a mounting groove, and the flipping action can use the mounting groove to accurately position the installation area of ​​the electrical equipment, thereby achieving a fixed connection between the electrical equipment and the sliding frame by screws.

[0013] According to the above technical solution, an elastic rod is fixedly connected to the inner wall of the first through hole, and a first contact is fixedly connected to the outer wall of the elastic rod on one side close to the first mounting rod, and a connecting piece is fixedly connected to the outer wall of the first mounting rod on one side close to the first contact, and the elastic rod is made of elastic memory metal, specifically copper-based memory alloy.

When the two ends of the first mounting rod are installed in place, the first contact at the end of the elastic rod contacts the connecting piece. At this time, the connecting piece will guide the grounding current generated on the metal track to the first contact, and the first contact will then transmit the grounding current to the transmission wire inside the support frame through the elastic rod.

The grounding current on the support frame is guided to the second contact through the elastic component, and then the second contact guides the grounding current to the power exchange cabinet. Thereafter, the grounding current is introduced into the underground through an external grounding device arranged outside the power exchange cabinet.

[0015] Compared with the prior art, the present invention provides a grounding device in a converter station, which has the following beneficial effects: 1.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Example 1: See Figure 1-Figure 4The present invention provides a technical solution: a grounding device in a converter station, comprising a power exchange cabinet 1 and an adjustment mechanism 5, wherein a support foot 2 is fixedly connected to the bottom outer wall of the power exchange cabinet 1, and the support foot 2 is made of an insulating material. An external grounding device is arranged outside the power exchange cabinet 1 to discharge the grounding current inside the power exchange cabinet 1, and a cabinet door 3 is rotatably connected to the front of the power exchange cabinet 1 through a hinge. A support mechanism 4 is arranged inside the power exchange cabinet 1, and the support mechanism 4 comprises a support frame 401 fixedly connected to the inner wall of the power exchange cabinet 1, and a first groove 402 is provided on the inner wall of the support frame 401, and a first mounting rod 405 is slidably connected to the inner wall of the first groove 402, and a first through hole 406 is provided on the outer surface of the first mounting rod 405, and a metal track 407 is fixedly connected to the inner wall of the first mounting rod 405, and the adjustment mechanism 5 comprises: Sliding frame 501, the sliding frame 501 is slidably connected to the outer surface of the first mounting rod 405, the outer wall of the sliding frame 501 is fixedly connected with a fixed shaft 502, the inner wall of the sliding frame 501 is provided with a second groove 503, the back of the sliding frame 501 is provided with a second through hole 504, the outer wall of the sliding frame 501 on one side close to the fixed shaft 502 is fixedly connected with a fixed block 505, the outer wall of the sliding frame 501 on one side close to the second through hole 504 is fixedly connected with a first fixed frame 507, the inner wall of the first fixed frame 507 is fixedly connected with an elastic guide sheet 508, the bottom outer wall of the first fixed frame 507 is fixedly connected with a fixed rod 509, and the fixed rod 509 is away from the outer wall of the first fixed frame 507 A third contact 510 is fixedly connected. When the electrical equipment is installed outside the sliding frame 501, an electric wire can be used to establish a connection between the electrical equipment and the third contact 510. Then, the electric wire will serve as a conductive medium to transmit the grounding current in the electrical equipment to the fixed rod 509 with the help of the third contact 510. Then, the fixed rod 509 will take on the task of continuing to conduct the grounding current and guide the grounding current to the elastic guide plate 508. Since the elastic guide plate 508 and the metal rail 407 are in a sliding connection, the grounding current will follow this connection channel and be further guided to the support frame 401 through the metal rail 407, thereby completing the conduction path of the grounding current from the electrical equipment to the support frame 401.

[0025] An elastic rod 403 is fixedly connected to the inner wall of the first through hole 406, and a first contact 404 is fixedly connected to the outer wall of the elastic rod 403 near the first mounting rod 405. A connecting piece 408 is fixedly connected to the outer wall of the first mounting rod 405 near the first contact 404. The elastic rod 403 is made of elastic memory metal, specifically copper-based memory alloy. When the two ends of the first mounting rod 405 slide toward the inside of the first groove 402, the first contact 404 located therein is squeezed. This squeezing makes the elastic rod 403 3 is deformed, and as the two ends of the first mounting rod 405 continue to slide until they are installed in place, the first contact 404 at the end of the elastic rod 403 will contact the connecting piece 408. At this time, the connecting piece 408 plays its conductive role and guides the grounding current generated on the metal track 407 to the first contact 404. Then, the first contact 404 transmits the grounding current to the transmission wire inside the support frame 401 with the help of the elastic rod 403, thereby completing the conduction path of the grounding current between this series of components, ensuring the normal operation of the grounding function of the entire system.

[0026] An elastic component 409 is fixedly connected to the outer wall of the support frame 401 on the side away from the cabinet door 3, and a second contact 410 is fixedly connected to the outer wall of the elastic component 409 on the side away from the support frame 401. The second contact 410 is fixedly connected to the power exchange cabinet 1 on the side away from the elastic component 409. The elastic component 409 is made of copper-aluminum-nickel alloy, which has elasticity, conductivity and shape memory functions. The grounding current generated on the support frame 401 is first conducted through the elastic component 409. Under the guidance of the elastic component 409, the grounding current is accurately guided to the second contact 410. After receiving the grounding current, the second contact 410 will further guide it to the power exchange cabinet 1. When the grounding current reaches the power exchange cabinet 1, it continues to flow along a predetermined path, and is finally smoothly introduced into the underground through an external grounding device specially arranged outside the power exchange cabinet 1, thereby realizing the entire grounding process and ensuring the safety of electricity use.

[0027] Example 2: Please refer to Figure 5-Figure 10On the basis of the first embodiment, the present invention provides a technical solution: the auxiliary component 511 comprises a force block 5111 arranged outside the sliding frame 501, the outer wall of the force block 5111 close to the sliding frame 501 is fixedly connected with a connecting shaft 5112, the outer surface of the connecting shaft 5112 away from the force block 5111 is slidably connected with the second through hole 504, the outer wall of the force block 5111 close to the sliding frame 501 is fixedly connected with a first spring 5113, and one end of the first spring 5113 away from the force block 5111 is connected to the sliding frame 501 is fixedly connected. When the electrical equipment is installed outside the sliding frame 501, its back will squeeze the force-bearing block 5111. The force-bearing block 5111, as an intermediate transmission component, will be displaced after being squeezed, and transmit this force to the fixed shaft 502, so that the fixed shaft 502 moves toward the elastic guide piece 508. Under the push of the fixed shaft 502, the fixed shaft 502 contacts the elastic guide piece 508, and the elastic guide piece 508 applies pressure to the metal track 407 through the third through hole 506, so that the elastic guide piece 508 is deformed.

[0028] The inner wall of the force-bearing block 5111 is rotatably connected to the first rotating rod 5114 through a rotating shaft, and the end of the first rotating rod 5114 away from the force-bearing block 5111 is rotatably connected to the sliding block 5115 through a rotating shaft. The inner wall of the sliding block 5115 is slidably connected to the sliding frame 501. When the electrical equipment is installed outside the sliding frame 501, the back of the electrical equipment will squeeze the force block 5111. When the force block 5111 is squeezed, it will transmit the force to the sliding blocks 5115 on both sides through the first rotating rod 5114, so that the sliding blocks 5115 move outward. As the sliding blocks 5115 move outward, the extended length increases, thereby forming a certain distance between the two sides of the electrical equipment. The formation of this distance is achieved through mechanical transmission between the force-bearing block 5111, the first rotating rod 5114 and the sliding block 5115, which can ensure that the electrical equipment maintains a stable and reasonable layout at the installation position.

[0029] The outer wall of the sliding block 5115 is fixedly connected to a push plate 5116, and the outer wall of the sliding block 5115 on the side away from the push plate 5116 is fixedly connected to a second spring 5117, and the end of the second spring 5117 away from the sliding block 5115 is fixedly connected to the sliding frame 501. When the electrical equipment is removed from the sliding frame 501, the sliding block 5115, which was previously pushed outward by the first rotating rod 5114 due to the squeezing of the force block 5111, begins to reset under the elastic force of the second spring 5117. Due to the connection relationship between the sliding block 5115, the first rotating rod 5114 and the force block 5111, as the sliding block 5115 is reset, it will transmit the force back to the force block 5111 through the first rotating rod 5114, so that the force block 5111 also returns to its original initial position when it is not squeezed, and is ready for the next installation and use of the electrical equipment.

[0030] The mounting assembly 512 includes an extrusion block 5121 arranged outside the fixed shaft 502, and the bottom outer wall of the extrusion block 5121 is fixedly connected to a second fixed frame 5122, and the bottom outer wall of the second fixed frame 5122 is fixedly connected to a third spring 5123, and the third spring 5123 is fixedly connected to the sliding frame 501 on the side away from the second fixed frame 5122, and the inner wall of the second fixed frame 5122 is slidably connected to the fixed shaft 502. When the extrusion block 5121 is subjected to external extrusion, it will transmit the extrusion force it receives to the third spring 5123 through the second fixed frame 5122, so that the third spring 5123 is compressed. In this process, the existence of the fixed shaft 502 has a key limiting effect on the sliding distance of the second sliding frame 501. As the extrusion continues, when the bottom of the extrusion block 5121 contacts the top of the fixed shaft 502, the extrusion block 5121 and the second fixed frame 5122 will move to the lowest point in the entire stroke under the combined action of the extrusion force and the limiting conditions.

[0031] The inner wall of the extrusion block 5121 is rotatably connected to the second rotating rod 5124 via a rotating shaft, and the outer wall of the second rotating rod 5124 on the side away from the extrusion block 5121 is rotatably connected to the second mounting rod 5125 via a rotating shaft. The bottom of the second mounting rod 5125 is rotatably connected to the fixed block 505, and the outer surface of the second mounting rod 5125 is provided with a mounting groove 5126. When the extrusion block 5121 is pressed, the extrusion block 5121 will transmit force to the second mounting rod 5125 with the help of the second rotating rod 5124 under the drive of pressure. Under the action of this force, the second mounting rod 5125 will flip over. Since the outer surface of the second mounting rod 5125 is provided with a mounting groove 5126, during its flipping process, the mounting groove 5126 can accurately locate the installation area of ​​the electrical equipment according to a specific design and position relationship. Through this precise positioning, the electrical equipment can be smoothly fixedly connected to the sliding rack 501 using screws later.
