Description

Technical Field

[0001] The utility model relates to the technical field of ring network switch equipment, in particular to AC high-voltage ring network switch equipment. Background Art

[0002] The ring network switch cabinet is an electrical device in which a group of high-voltage switchgear is installed in a steel plate metal cabinet or made into an assembled interval ring network power supply unit. Its core part adopts load switches and fuses, which has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. Some switchgear for controlling and switching internal electrical components will be installed on the ring network switch cabinet; Patent No. CN202020860571.3 announced a new type of AC high-voltage ring network switchgear. By setting wiring pins, No. 3 sealing rings and conductive copper sheets, personnel use tools to connect the connecting wires of electrical equipment to the terminals respectively. At one end of the wire pin, after the connection is completed, the protective rubber sleeve on the outside of the wiring pin is moved to the connection to protect the connection and prevent the wiring pin from disconnecting from the connection wire. The No. 3 sealing ring acts as a seal between the wiring pin and the tube body to prevent dust, water stains, etc. from entering the tube body. Multiple conductive copper sheets are welded to the inside of the sleeve. After the sleeve is sleeved on one end of the wiring pin, the multiple conductive copper sheets are tightly attached to the outside of the wiring pin, improving the conductivity between the wiring pin and the sleeve. However, when the resistance wire inside the switch is blown, the entire switch can only be replaced, rather than the resistance wire alone, which is wasteful. To this end, we propose an AC high-voltage ring network switchgear. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides an AC high-voltage ring network switch device.

[0004] The technical solution adopted by the utility model to solve the technical problem is an AC high-voltage ring network switchgear, comprising a tube shell, a tube seat slidably mounted in the tube shell, and a tube shell sleeved on the outer periphery of the tube seat, a screw body threadedly mounted on the outer wall surface of the tube shell and screwedly connected to the tube seat, and multiple groups of screw bodies, one end of the tube seat located in the tube shell is equipped with a backing plate, and a circuit board is mounted on the surface of the backing plate, and a buckle seat is mounted on the surface of the circuit board, and there are two groups of buckle seats, and a fuse tube is clamped between the two groups of buckle seats;

[0005] A card plate that is engaged with the fuse tube is slidably installed in the buckle seat, and a ring shell for support is screwed on the outer wall surface of the buckle seat. A spring for pushing the card plate to move is installed between the ring shell and the card plate. A sponge pad that abuts the fuse tube is adhered to one side of the circuit board located between the two sets of buckle plates.

[0006] By adopting the above technical solution, when the resistance wire inside the AC high-voltage ring network switch is blown, the cylindrical shell inside the shell can be pulled, so that the cylindrical shell drives the cylindrical seat inside the shell to move, and the circuit between the cylindrical seat and the inside of the shell will be disconnected. Then, the screw body between the cylindrical shell and the cylindrical seat can be removed, and the cylindrical shell clamped on the outside of the cylindrical seat can be removed, so that the fuse tube between the two sets of buckle plates on the circuit board on the surface of the base plate of the cylindrical seat can be removed, which is convenient for replacement. After the replacement is completed, the switch equipment can continue to be used, which is convenient for cost saving, simple disassembly and assembly, and convenient for replacement.

[0007] When replacing the fuse tube, the fuse tube can be conveniently clamped between the two groups of buckle plates on the surface of the circuit board, and the spring inside the buckle plate can push the clamping plate to move, so that one end of the clamping plate can extend out of the buckle plate and engage with the grooves at both ends of the fuse tube, so that the fuse tube can be stably clamped between the two groups of buckle plates, which is convenient for use. At the same time, the ring shell on the outer side of the buckle plate can be unscrewed to remove the spring between the ring shell and the clamping plate, which is convenient for replacement.

[0008] Specifically, a ring seat is assembled on the outer wall surface of the backing plate, and a ring cover located in the cylindrical shell is screwed and mounted on the outer periphery of the ring seat.

[0009] By adopting the above technical solution, the transparent ring cover is screwed onto the outer periphery of the ring seat, which is convenient for auxiliary protection of the circuit board on the surface of the pad, and is easy to disassemble and assemble, making it convenient to maintain the structure on the surface of the circuit board.

[0010] Specifically, an annular groove is provided on the outer peripheral surface of the cylindrical shell.

[0011] By adopting the above technical solution, the annular groove on the outer side of the cylindrical shell makes it simple and convenient to lift the cylindrical shell.

[0012] Specifically, a ring for fastening is screwed onto the outer periphery of the tube shell, and rubber rings are bonded to opposite sides of the ring and the tube shell.

[0013] By adopting the above technical solution, the ring and the threads on the outer periphery of the tube shell are screwed together, which makes it easy to install the tube shell at a corresponding position. At the same time, the rubber ring helps to improve the tightness of the tube shell after it is fixed.

[0014] Specifically, an indicator light electrically connected to the fuse tube is mounted on the surface of the circuit board.

[0015] By adopting the above technical solution, the indicator light can generate light when the fuse tube is operating, so that personnel can clearly understand that the circuit is in a connected state. At the same time, when the resistance wire inside the fuse tube is blown, the indicator light will stop operating.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application is designed with a cylinder seat, a cylinder shell, a screw body, a pad, a circuit board, a buckle plate and a fuse tube. When the resistance wire inside the AC high-voltage ring network switch is blown, the cylinder shell inside the cylinder shell can be pulled, so that the cylinder shell drives the cylinder seat inside the cylinder shell to move, and the circuit inside the cylinder seat and the cylinder shell will be disconnected. Then, the screw body between the cylinder shell and the cylinder seat can be removed, and the cylinder shell clamped on the outside of the cylinder seat can be removed, so that the fuse tube between the two groups of buckle plates on the circuit board on the pad surface of the cylinder seat can be removed, which is convenient for replacement. After the replacement is completed, the switch equipment can continue to be used, which is convenient for saving cost consumption, and the disassembly and assembly are simple, and replacement is convenient.

When replacing the fuse tube, the fuse tube can be conveniently clamped between the two sets of buckle plates on the surface of the circuit board, and the spring inside the buckle plate can push the clamping plate to move, so that one end of the clamping plate can extend out of the buckle plate and engage with the grooves at both ends of the fuse tube, so that the fuse tube can be stably clamped between the two sets of buckle plates, making it convenient to use. At the same time, by unscrewing the ring shell on the outside of the buckle plate, the spring between the ring shell and the clamping plate can be removed, making it easy to replace it.
