Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-voltage direct current transmission, in particular to a grounding device in a converter station. BACKGROUND

[0002] The grounding of the converter station is mainly considered from the aspects of safety and operation. From the safety aspect, it can avoid electric shock of personnel. If the electrical equipment of the converter station is electrified, the grounding can introduce the current into the ground to ensure the safety of personnel contacting the equipment shell. At the same time, the equipment is protected. When the overvoltage occurs, the electric charge can be introduced into the ground to prevent the insulation of the equipment from being broken down. From the operation aspect, it can provide a stable reference potential for the control and protection system, reduce electromagnetic interference, and help fault protection and positioning to ensure the reliable operation of the converter station.

[0003] The patent application with the application number CN201721273276.2 discloses a grounding device in a converter station and a direct current transmission system, and relates to the field of high-voltage direct current transmission.

During this process, the presence of the fixed shaft 502 plays a crucial role in limiting the sliding distance of the second sliding frame 501. As the pressure continues, when the bottom of the pressing block 5121 contacts the top of the fixed shaft 502, the pressing block 5121 and the second fixed frame 5122 will move to the lowest point of the entire stroke under the combined action of the pressure and the limiting conditions.

When the extrusion block 5121 is pressed, the extrusion block 5121, driven by pressure, will transmit force to the second mounting rod 5125 through the second rotating rod 5124. Under the action of this force, the second mounting rod 5125 will flip. 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 position the installation area of ​​the electrical equipment according to a specific design and positional relationship. Through this precise positioning, the electrical equipment can be easily fixedly connected to the sliding frame 501 using screws.

The bottom of the second mounting rod (5125) is rotatably connected to a fixing block (505). The outer surface of the second mounting rod (5125) is provided with a mounting groove (5126). When the extrusion block (5121) is under pressure, the second rotating rod (5124) pushes the second mounting rod (5125) to cause the second mounting rod (5125) to flip to both sides. The flipped second mounting rod (5125) is used to locate the installation point of the electrical equipment.

6. A grounding device for a converter station according to claim 1, characterized in that: An elastic rod (403) is fixedly connected to the inner wall of the first through hole (406). 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 connecting piece (408) is used to guide the grounding current generated on the metal rail (407) to the first contact (404). The first contact (404) then transmits the grounding current to the transmission wire inside the support frame (401) through the elastic rod (403).

7. A grounding device for a converter station according to claim 6, characterized in that: An elastic component (409) is fixedly connected to the outer wall of the support frame (401) away from the cabinet door (3). A second contact (410) is fixedly connected to the outer wall of the elastic component (409) away from the support frame (401). The side of the second contact (410) away from the elastic component (409) is fixedly connected to the power exchange cabinet (1). The elastic component (409) is used to absorb the vibration generated by the power equipment on the support frame (401), so that the second contact (410) contacts the bottom of the power exchange cabinet (1) when the power equipment is working.
