Description
Technical Field
[0001] The present invention relates to the technical field of high-voltage switches, and in particular to an outdoor AC high-voltage switch and a manufacturing method thereof. Background Art
[0002] Outdoor AC high-voltage switch is a kind of switchgear widely used in power systems, mainly used to control, protect and isolate power equipment, such as power transmission and transformation lines, substation equipment, etc. In the power system, with the continuous expansion of the scale of the power grid and the increase in power demand, the performance requirements for switchgear are getting higher and higher, and the existing outdoor AC high-voltage switch still has some shortcomings.
[0003] For example, the invention patent with the publication number CN100590762C discloses an outdoor AC high-voltage grounding switch, which includes a column, a frame crossbeam, a hand-cranked mechanism, an insulating support, a conductive tube flip box, a conductive tube, a moving contact and a static contact seat. The transmission crank arm is installed in the frame crossbeam, the transmission crank arm is connected to the primary transmission connecting rod, the primary transmission connecting rod is connected to the crank arm of the transmission main shaft, the transmission main shaft drives the shift fork installed on the coaxial axis, the shift fork drives the conductive rod and the limit pin, and rotates about 90 degrees with the main shaft as the center of the circle. When the moving contact enters the static contact seat, the limit pin passes over the limit plate. Under the action of the shift fork, the conductive rod rotates 40 degrees and the moving contact opens the contact finger to complete the closing. There is no lateral impact force and longitudinal force on the porcelain column during the closing process. The rotating joints of the transmission system will not be directly eroded by rain and snow and direct sunlight, which improves the rust resistance of the transmission joints. The interphase transmission is a rotation transmission, and the transmission stroke is not affected by temperature. The high-voltage grounding switch can be used in various isolating switches or used alone. Although the above switch can achieve the functions of reducing impact force and preventing erosion, it cannot achieve the automatic lubrication function when in use, and cannot automatically stop lubrication when the switch is opened. In addition, the existing high-voltage switch is not safe enough, and the clamping structure cannot be pulled while maintaining insulation.

The first connecting plate can move in the movable groove and can be prevented from falling off the pressure rod through the protrusion and the first through hole, thereby ensuring the safety of the device in use and solving the problem that the existing high-voltage switch cannot pull the clamping structure while maintaining insulation.

The device can remove and replace a new extension tube 2402 during lubrication, and can also directly install a new docking component 24 above the extension tube 2402 to achieve the function of automatically replenishing the lubricating liquid.
[0034] A method for manufacturing an outdoor AC high voltage switch comprises the following steps: The base 1 is made of a steel plate that is hot-dip galvanized after stamping or made of stainless steel. The contact flaps of the first high-strength porcelain insulator 2 and the second high-strength porcelain insulator 3 are made of chromium-zirconium-copper. The first support plate 4, the second support plate 5, the first connecting plate 10 and the second connecting plate 15 are all made of red copper T2. The conductive belt 8 is fixed to the pressure rod 7 and the second support plate 5 by bolts, the bottom of the switching component 13 is welded to the lap ring 12, and the first fixing tube 21 is welded to both sides of the second support plate 5 and connected to the top of the connecting component 20.
[0035] It should be noted that the present invention is an outdoor AC high voltage switch and a manufacturing method thereof. First, Figure 1-Figure 3 As shown, the switch is in the closed state at this time. The insulating cylinder 1302 on the switching assembly 13 can be held to drive the pressure rod 7 to rotate 90° counterclockwise, so that the conductive belt 8 is compressed. The elastic force of the conductive belt 8 increases at this time. The position of the lap ring 12 can be adjusted by the insulating cylinder 1302 and the connecting rod 1301, thereby changing the position of the first connecting plate 10, thereby ensuring the safety of the device when in use. The first connecting plate 10 is inserted into the second through hole 16 in the second connecting plate 15 on the first support plate 4. Under the elastic force of the conductive belt 8, the first connecting plate 10 and the second connecting plate 15 remain in a clamped state, thereby turning on the switch. Figure 4 As shown, the third stopper 1306 on the switching assembly 13 can play a shielding function. When the first stopper 1304 and the second stopper 1305 on the slide 1303 are pushed, the slide 1303 can be driven to move, and the third stopper 1306 can prevent the slide 1303 from detaching from the device.
[0036] like Figure 1 and Figure 4-Figure 10As shown, during the process of the switch being turned on, the rotating shaft 6 in the second supporting plate 5 rotates counterclockwise. Since the outer cylinder 2005 on the connecting component 20 is fixedly connected to the first fixed cylinder 21, and the first fixed cylinder 21 is fixedly connected to the second supporting plate 5, when the rotating shaft 6 rotates, the first connecting ring 18 and the baffle 19 remain stationary, so that the gap between the first connecting ring 18 and the baffle 19 is connected to the third through hole 1701 on the lubricating component 17. At this time, the lubricating fluid in the first fixed cylinder 21 passes through the fifth through hole 200 6 flows into the gap between the second connecting ring 2001 and the third connecting ring 2003, and then flows into the connecting groove 1702 through the third through hole 1701. The lubricating liquid will also wet the scraper 1704 and the bristles 1705, and enter the interior of the inner groove 1703 through the fourth through hole 1706. The connecting rod 2002 is used to support the second connecting ring 2001 and the third connecting ring 2003. As the rotating shaft 6 continues to rotate, the bristles 1705 will evenly coat the lubricating liquid on the inner groove 1703, thereby realizing the automatic lubrication function after turning on the switch. The device can splice multiple docking components 24. When the sliding sleeve 2403 is pushed upward by the connecting mesh tube 2408 on the docking component 24 below or the installing mesh tube 23 on the side rod 22, the spring 2405 will be compressed and the sliding sleeve 2403 slides on the inner rod 2404. At this time, the mesh structure on the connecting mesh tube 2408 or the installing mesh tube 23 is interconnected with the upper space, thereby opening the connecting channel to allow the lubricating fluid to automatically flow into the lower layer, so that the device can automatically replenish the lubricating fluid.
[0037] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
