Description

Technical Field

[0001] This utility model relates to the field of high-voltage power transmission technology, specifically a shielding component for high-voltage power transmission. Background Technology

[0002] High-voltage power transmission is a method of transmitting electricity by stepping up the voltage output from generators using transformers at power plants. This method is chosen because, for the same transmission power, higher voltage results in lower current. This reduces the current during transmission, thus lowering heat loss and material costs for long-distance transmission. At the connection points of high-voltage transmission lines, electric arcs can occur during opening and closing. Shielding covers are crucial components protecting high-voltage transmission equipment, serving to shield against electric arcs. Arc shielding assemblies for high-voltage transmission are essential components used to prevent damage to equipment and personnel from electric arcs during high-voltage transmission. Common types include isolation covers, equalizing shielding rings, and arc-damping angles.

[0003] Currently, existing shielding components for high-voltage power transmission are inconvenient for handling electric arcs, and the high temperature of the arcs can easily cause harm to equipment and personnel, posing a significant safety hazard. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a shielding component for high-voltage power transmission, which solves the problems of inconvenience in handling electric arcs, high arc temperatures, easy harm to equipment and personnel, and significant safety hazards.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A shielding assembly for high-voltage power transmission includes:

[0007] A first semicircular protective cover and a second semicircular protective cover are provided. A hinge is installed between the side of the surface of the first semicircular protective cover and the side of the surface of the second semicircular protective cover. A base block is fixedly installed at the end of the second semicircular protective cover away from the hinge. A connecting ear is fixedly installed at the end of the first semicircular protective cover away from the hinge. An opening and closing component is installed on the side of the inner cavity of the first semicircular protective cover.

[0008] An arc-extinguishing mechanism includes a connecting seat, which is fixedly installed on the side of the inner side of the first semicircular protective cover. A right-angled connecting plate is fixedly installed at the bottom of the connecting seat. A baffle is fixedly connected to the top side of the inner side of the right-angled connecting plate. The surface of the baffle has through holes. A grid plate is fixedly connected to the top of the inner side of the right-angled connecting plate. The bottom of the grid plate has an inverted V-shaped notch. The grid plates are evenly distributed on the top of the inner side of the right-angled connecting plate. When an electric arc occurs in the inner cavity of the first and second semicircular protective covers, the multiple grid plates can divide the electric arc into several short arc segments and extinguish these short arc segments, thereby achieving the effect of arc extinguishing and shielding.

[0009] Preferably, the first semicircular protective cover and the second semicircular protective cover are hinged together by a hinge, and the first semicircular protective cover and the second semicircular protective cover are installed at the same height.

[0010] By having the electric arc come into contact with the inverted V-shaped notch, the contact area can be increased. Multiple sets of grids work together to absorb and dissipate the heat from the electric arc. The baffles are installed at an angle, and the surface of the baffles is evenly perforated, which allows for faster ventilation and heat dissipation, enabling the electric arc to cool down quickly and further promoting arc extinguishing.

[0011] Preferably, the connecting ear and the base block are installed at the same height, and the connecting ear and the base block are fixedly installed by screws.

[0012] By rotating the first semicircular protective cover and the second semicircular protective cover together, a closed space can be formed between the first semicircular protective cover and the second semicircular protective cover. The base block and connecting lug can be fixed by screws, thus protecting the arc extinguishing mechanism and the opening and closing assembly.

[0013] When it is necessary to open, simply unscrew the screws on the base block, and the first and second semicircular protective covers can be rotated in opposite directions to open.

[0014] Preferably, the baffles are installed at an angle, and there are two baffles, which are symmetrically installed along the right-angled connecting plate.

[0015] Preferably, the grid plates are evenly distributed on the top of the inner side of the angular connecting plate, and the inverted V-shaped notch gradually decreases in size from top to bottom.

[0016] Preferably, the opening and closing assembly includes an inlet terminal and an outlet terminal. The inlet terminal is fixedly installed on the side of the bottom of the inner cavity of the first semi-circular protective cover, and the outlet terminal is fixedly installed on the side of the top of the inner cavity of the first semi-circular protective cover. A swing gate is hinged to the bottom of the surface of the outlet terminal, and an insulating block is fixedly connected to the middle of the surface of the swing gate. A connecting cable is fixedly connected between the top of the swing gate and the outlet terminal. An elastic clamp is fixedly connected to the top of the surface of the inlet terminal to pull one end of the inlet cable from the first semi-circular protective cover. The bottom of the circular protective cover is inserted, and one end of the incoming cable is fixedly installed to the incoming terminal. One end of the outgoing cable is inserted from the top of the first semi-circular protective cover and fixedly installed to the outgoing terminal. The insulating block is pushed, causing the swing gate to rotate counterclockwise, so that the bottom of the swing gate can be embedded into the interior of the elastic clamp, thus connecting the circuit. When it is necessary to disconnect the circuit, the insulating block is pulled, causing the swing gate to rotate clockwise. The swing gate disengages from the elastic clamp, thus disconnecting the circuit. An electric arc is generated when the circuit is disconnected.

[0017] Preferably, the incoming line terminal and the outgoing line terminal are insulated from the inner wall of the first semi-circular protective cover.

[0018] Beneficial effects

[0019] This invention provides a shielding assembly for high-voltage power transmission. It has the following advantages:

[0020] 1. The shielding assembly for high-voltage power transmission utilizes grids evenly distributed on the top of the inner side of the angled connecting plate. When an electric arc occurs in the inner cavity of the first and second semi-circular protective covers, multiple sets of grids can divide the electric arc into several short arc segments and extinguish these segments, thereby achieving the effect of arc extinguishing and shielding.

[0021] Second, the shielding component for high-voltage power transmission increases the contact area by having the electric arc contact the inverted V-shaped notch. Multiple sets of grids absorb and dissipate heat from the electric arc together. The baffles are installed at an angle and have uniform through holes on their surface, which allows for faster ventilation and heat dissipation, enabling the electric arc to cool down quickly and further promoting arc extinguishing.

[0022] Third, the shielding assembly for high-voltage power transmission can form a closed space by rotating the first semicircular protective cover and the second semicircular protective cover together in opposite directions. The base block and connecting lugs are fixed with screws, which can protect the arc extinguishing mechanism and the opening and closing assembly. When it is necessary to open, simply unscrew the screws on the base block and the first semicircular protective cover and the second semicircular protective cover can be rotated in opposite directions to open.

[0023] IV. This high-voltage power transmission shielding assembly is fixedly installed with the cable through the incoming and outgoing terminals. Pushing the insulating block causes the swing gate to rotate counterclockwise, so that the bottom end of the swing gate can be embedded into the interior of the elastic clamp, thus connecting the circuit. When it is necessary to disconnect the circuit, the insulating block is pulled, causing the swing gate to rotate clockwise. The swing gate disengages from the elastic clamp, thus disconnecting the circuit. An electric arc is generated when the circuit is disconnected. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-5 This utility model provides a technical solution: a shielding assembly for high-voltage power transmission, comprising:

[0032] A first semicircular protective cover 1 and a second semicircular protective cover 2 are provided. A hinge 3 is installed between the side of the surface of the first semicircular protective cover 1 and the side of the surface of the second semicircular protective cover 2. A base block 4 is fixedly installed at the end of the second semicircular protective cover 2 away from the hinge 3. A connecting ear 5 is fixedly installed at the end of the first semicircular protective cover 1 away from the hinge 3. An opening and closing component 6 is installed on the side of the inner cavity of the first semicircular protective cover 1.

[0033] Arc extinguishing mechanism 7 includes a connecting seat 71, which is fixedly installed on the side of the inner side of the first semicircular protective cover 1. A right-angled connecting plate 72 is fixedly installed at the bottom of the connecting seat 71. A baffle 73 is fixedly connected to the top side of the inner side of the right-angled connecting plate 72. A through hole 74 is opened on the surface of the baffle 73. A grid plate 75 is fixedly connected to the top of the inner side of the right-angled connecting plate 72. An inverted V-shaped notch 76 is opened at the bottom of the grid plate 75. The grid plates 75 are evenly distributed on the top of the inner side of the right-angled connecting plate 72. When an electric arc occurs in the inner cavity of the first semicircular protective cover 1 and the second semicircular protective cover 2, the multiple sets of grid plates 75 can divide the electric arc into several short arc segments and extinguish these short arc segments, thus performing arc extinguishing shielding.

[0034] The first semicircular protective cover 1 and the second semicircular protective cover 2 are hinged together by a hinge 3, and the first semicircular protective cover 1 and the second semicircular protective cover 2 are installed at the same height.

[0035] The connecting ear 5 and the base block 4 are installed at the same height and are fixed to each other by screws. The electric arc contacts the inverted V-shaped notch 76, which increases the contact area. Multiple sets of grid plates 75 absorb and dissipate the heat of the electric arc together. The baffle 73 is installed at an angle and the surface of the baffle 73 is evenly opened with through holes 74, which makes ventilation and heat dissipation faster, so that the electric arc cools down quickly and further promotes arc extinguishing.

[0036] The baffle 73 is installed at an angle. There are two baffles 73, and the two baffles 73 are installed symmetrically along the right-angled connecting plate 72.

[0037] The grid plates 75 are evenly distributed on the top of the inner side of the angled connecting plate 72. The inverted V-shaped notch 76 gradually decreases in size from top to bottom. By rotating the first semicircular protective cover 1 and the second semicircular protective cover 2 together in opposite directions, the first semicircular protective cover 1 and the second semicircular protective cover 2 can form a closed space. The base block 4 and the connecting ear 5 are fixed by screws, which can protect the arc extinguishing mechanism 7 and the opening and closing assembly 6. When it is necessary to open, simply unscrew the screws on the base block 4, and the first semicircular protective cover 1 and the second semicircular protective cover 2 can be rotated in opposite directions to open.

[0038] The opening / closing assembly 6 includes an inlet terminal 61 and an outlet terminal 62. The inlet terminal 61 is fixedly installed on the side of the bottom of the inner cavity of the first semi-circular protective cover 1, and the outlet terminal 62 is fixedly installed on the side of the top of the inner cavity of the first semi-circular protective cover 1. A swing gate 63 is hinged to the bottom of the surface of the outlet terminal 62. An insulating block 64 is fixedly connected to the middle of the surface of the swing gate 63. A connecting cable 65 is fixedly connected between the top of the swing gate 63 and the outlet terminal 62. An elastic clamp 66 is fixedly connected to the top of the surface of the inlet terminal 61 to pull one end of the inlet cable from the first semi-circular protective cover 1. The bottom end of the cable is inserted, and one end of the incoming cable is fixedly installed to the incoming terminal 61. One end of the outgoing cable is inserted from the top of the first semi-circular protective cover 1 and fixedly installed to the outgoing terminal 62. The insulating block 64 is pushed, causing the swing gate 63 to rotate counterclockwise, so that the bottom end of the swing gate 63 can be embedded in the interior of the elastic clamp 66, thus connecting the circuit. When it is necessary to disconnect the circuit, the insulating block 64 is pulled, causing the swing gate 63 to rotate clockwise. The swing gate 63 disengages from the elastic clamp 66, thus disconnecting the circuit. An electric arc is generated when the circuit is disconnected.

[0039] The incoming terminal 61 and the outgoing terminal 62 are insulated from the inner wall of the first semi-circular protective cover 1.

[0040] When in use, first unscrew the screws on the base block 4, and then the first semicircular protective cover 1 and the second semicircular protective cover 2 can be rotated in opposite directions to open;

[0041] Then, insert one end of the incoming cable through the bottom of the first semicircular protective cover 1 and fix one end of the incoming cable to the incoming terminal 61. Insert one end of the outgoing cable through the top of the first semicircular protective cover 1 and fix one end of the outgoing cable to the outgoing terminal 62. Push the insulating block 64 to make the swing gate 63 rotate counterclockwise, so that the bottom end of the swing gate 63 can be embedded into the interior of the elastic clamp 66, so that the circuit is connected. By rotating the first semicircular protective cover 1 and the second semicircular protective cover 2 together, the first semicircular protective cover 1 and the second semicircular protective cover 2 can form a closed space. Fix the base block 4 and the connecting ear 5 with screws to protect the arc extinguishing mechanism 7 and the opening and closing assembly 6.

[0042] When it is necessary to disconnect the circuit, the insulating block 64 is pulled, causing the swing gate 63 to rotate clockwise. The swing gate 63 disengages from the elastic clamp 66, thus disconnecting the circuit. An electric arc is generated when the circuit is disconnected.

[0043] Furthermore, the grid plates 75 are evenly distributed on the top of the inner side of the angled connecting plate 72. When an electric arc occurs in the inner cavity of the first semicircular protective cover 1 and the second semicircular protective cover 2, the multiple sets of grid plates 75 can divide the electric arc into several short arc segments and extinguish these short arc segments to perform arc extinguishing shielding.

[0044] Furthermore, the contact area can be increased by the electric arc coming into contact with the inverted V-shaped notch 76, and multiple sets of grid plates 75 together absorb and dissipate the heat of the electric arc. The baffle 73 is installed at an angle, and the surface of the baffle 73 is evenly opened with through holes 74, which makes ventilation and heat dissipation faster, allowing the electric arc to cool down quickly and further promoting arc extinguishing.
