Description

Technical Field

[0001] The utility model relates to the field of five-prevention devices, and particularly to a five-prevention device for a high-voltage switch cabinet. Background Technique

[0002] With the continuous development of the national intelligent power grid, higher requirements are not only put forward in terms of product reliability, high quality, miniaturization, intelligence, environmental protection, and maintenance-free, but also strict requirements are imposed on the anti-misoperation of switchgear for the operation and maintenance and the personal safety of operators. Therefore, the national standard requires that high-voltage switchgear must have perfect "five-prevention" measures, namely (1) preventing misoperation of opening and closing the circuit breaker; (2) preventing misoperation of opening and closing the disconnector under load; (3) preventing personnel from entering the live compartment; (4) preventing closing the grounding switch when energized; (5) preventing power transmission with the grounding switch in the closing position. Therefore, domestic high-voltage switch cabinet manufacturers have developed and designed many different interlocking devices according to their actual production situations.

One side of the inner wall of the protective box fixed to the outer surface of the cabinet door penetrates through a first rotating rod. One end of the first rotating rod close to the inner wall of the cabinet door is provided with a first interlocking device. The other side of the inner wall of the protective box penetrates through a second rotating rod, which can effectively ensure the use safety of the staff during the operation process.

[0004] The rotating wheel of the above device is exposed outside, and anyone can use the rotating wheel to rotate the second rotating rod to control the opening of the cabinet door. Once the cabinet door is opened by an outsider, an electric shock accident may occur, and the safety of use is relatively poor. For this reason, a five-prevention device for a high-voltage switch cabinet is proposed. Content of the Utility Model

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the specific embodiments.

[0023] As Figure 1 Figure 2As shown in the figure, a five-prevention device for a high-voltage switch cabinet includes a cabinet door 1, on which a disconnector main body 2 is fixedly installed. A lock head 4 is provided on the disconnector main body 2, and a rotating rod 3 is arranged inside the disconnector main body 2. A sealing cover plate 8 is fixedly installed on the front surface of the disconnector main body 2, and a password switch 5 is fixedly installed on the upper surface of the disconnector main body 2. A driving mechanism 6 is connected to the rotating rod 3 inside the disconnector main body 2. The driving mechanism 6 includes a driving motor 606 fixed inside the disconnector main body 2 and a driven gear disk 601 fixed on the rotating rod 3. The output end of the driving motor 606 is fixedly installed with a driving gear disk 603. An emergency opening mechanism 7 is fixedly installed on the sealing cover plate 8. Only when the user inputs the correct password into the password switch 5 can the driving mechanism 6 be controlled to start. After the driving mechanism 6 starts, it will drive the rotating rod 3 to rotate, thereby controlling the cabinet door 1 to open, preventing outsiders from randomly opening the cabinet door 1 and improving the safety of use.

[0024] As Figure 3 shown, a password switch 5 is fixedly installed on the upper surface of the disconnector main body 2, and a driving mechanism 6 is connected to the rotating rod 3 inside the disconnector main body 2. The driving mechanism 6 includes a driving motor 606 fixed inside the disconnector main body 2 and a driven gear disk 601 fixed on the rotating rod 3. The output end of the driving motor 606 is fixedly installed with a driving gear disk 603. The driving mechanism 6 further includes a connection port 607 opened on the driven gear disk 601, a limit pin 602 is arranged inside the connection port 607, a motor base 604 is fixedly installed on the driving motor 606, and a docking through hole 605 is opened on the motor base 604.

[0025] After the user inputs the correct password into the password switch 5, the driving motor 606 can be started. After the driving motor 606 starts, it will drive the driving gear disk 603 to rotate. After the driving gear disk 603 rotates, it will drive the driven gear disk 601 to rotate. After the driven gear disk 601 rotates, it will drive the rotating rod 3 to rotate. After the rotating rod 3 rotates, the cabinet door 1 will be opened. Using the password to control the opening of the cabinet door 1 can prevent outsiders from randomly opening the cabinet door 1 and improve the safety of use.

[0026] As Figure 4 shown, the emergency opening mechanism 7 includes a flat opening 706 opened at the end of the rotating rod 3 and a protective housing 703 fixed on the sealing cover plate 8. A prefabricated crack 704 is opened on the protective housing 703, a docking base 702 is fixedly installed on the protective housing 703, a positioning through hole 705 is opened on the docking base 702, and an anti-disassembly screw 701 is arranged inside the positioning through hole 705.

[0027] Specifically, the protective housing 703 can be fixed to the sealing cover plate 8 by the anti-disassembly screw 701 to block the slotted opening 706. In an emergency, a screwdriver can be used to pry open the protective housing 703. After the protective housing 703 is pried open, the slotted opening 706 will be exposed. After the slotted opening 706 is exposed, a flat-blade screwdriver can be inserted into the slotted opening 706, and the rotating rod 3 can be rotated by using the flat-blade screwdriver to open the cabinet door 1 in an emergency.

[0028] It should be noted that the present utility model is a five-prevention device for a high-voltage switchgear. In actual use, first, the correct password is input into the password switch 5. After the correct password is input into the password switch 5, the driving motor 606 can be started. Since the driving gear disk 603 is movably installed on one side of the driven gear disk 601 through the driving motor 606, and the driving gear disk 603 is engaged with the driven gear disk 601, the driven gear disk 601 is connected to the rotating rod 3 through the connection port 607, and the driven gear disk 601 is restricted on the rotating rod 3 by the limit pin 602. Therefore, after the driving motor 606 is started, it will rotate the driven gear disk 601. After the driven gear disk 601 rotates, it will drive the rotating rod 3 to rotate. After the rotating rod 3 rotates, the cabinet door 1 will be opened. In an emergency, a screwdriver can be used to pry open the protective housing 703. Since the anti-disassembly screw 701 passes through the docking base 702 through the positioning through hole 705, the protective housing 703 is fixed to the sealing cover plate 8 by the anti-disassembly screw 701. A through hole is provided on the sealing cover plate 8, and the through hole on the sealing cover plate 8 is aligned with the slotted opening 706 on the rotating rod 3 front and back. Therefore, after the protective housing 703 is pried open, the slotted opening 706 will be exposed. After the slotted opening 706 is exposed, a flat-blade screwdriver can be inserted into the slotted opening 706, and the rotating rod 3 can be rotated by using the flat-blade screwdriver to open the cabinet door 1 in an emergency, improving the safety of use.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
