Therefore, the provided padlock assembly 5 can ensure that the plug-in box 1 will not be opened by mistake when powered on, thereby improving the safety of the device.
[0028] The padlock assembly 5 includes two installation boxes 501, and the two installation boxes 501 are fixedly installed on the right outer surface of the plug-in box body 1. The two installation boxes 501 are both provided with grooves 502 inside, and the inner walls of the two grooves 502 are both fixedly installed with electromagnets 503. Two telescopic rods 504 are fixedly installed on one end of the cabinet door 2 close to the installation box 501, and reset springs 505 are fixedly installed on one end of the cabinet door 2 close to the installation box 501 and on the left and right sides of the two telescopic rods 504. Ferromagnetic materials 506 are fixedly installed on one end of the two telescopic rods 504 away from the cabinet door 2. The cabinet door 2 can be locked by the attraction between the electromagnet 503 and the ferromagnetic material 506. When the power is on, the set electromagnet 503 and the ferromagnetic material 506 can be used to prevent the cabinet door 2 from being opened. Only when the power is off can the cabinet door 2 be opened. Therefore, only when the power is off can the cabinet door 2 be unlocked and opened, thereby preventing misoperation in the powered state.
[0029] Embodiment 2
[0030] A bottom cable groove 6 is provided on the rear inner wall of the plug-in box 1, a joint box 7 is fixedly installed inside the plug-in box 1, a middle cable groove 8 is provided inside the plug-in box 1, a cable box 9 is fixedly installed inside the plug-in box 1, and a bottom cable groove 2 10 is provided on the front inner wall of the plug-in box 1.
[0031] In this embodiment, the middle cable tray 8 is located between the connector box 7 and the cable tray box 9 .
[0032] It should be noted that a cable duct is designed inside the plug-in box 1, which allows technicians to arrange each corresponding wire inside the cable duct after wiring is completed. This makes it easy to visually observe the arrangement of the lines during maintenance or inspection without feeling complicated.
[0033] In this embodiment, plug-in box fixing feet 3 are fixedly installed at the four corners of the bottom of the plug-in box body 1, and screw holes 4 are opened inside the four plug-in box fixing feet 3.
[0034] It should be noted that the plug-in box fixing feet 3 and the screw holes 4 are matched to fix the plug-in box body 1 by fastening bolts to prevent the plug-in box body 1 from moving.
[0035] In this embodiment, the bottom cable duct 2 10 is located below the cable box 9 , and the bottom cable duct 1 6 is located above the connector box 7 .
[0036] It should be noted that the junction box 7 is used to fix the terminal block and serves as a connector device, which can protect the temperature sensing element from corrosion by the external atmosphere and ensure good contact between the external wires and the terminal posts; the wiring box 9 is used to branch and transfer cables, which is particularly common in occasions such as railway distribution networks, and is used to achieve multi-branch cable connection; in addition, according to different application environments and requirements, the junction box 7 and the wiring box 9 have different models and materials, such as PVC and tin box materials, as well as splash-proof, waterproof and plug-in designs to adapt to different on-site environmental conditions.
[0037] In this embodiment, one end of the two sets of return springs 505 away from the cabinet door 2 is fixedly connected to the ferromagnetic material 506 , and the two ferromagnetic materials 506 extend into the slot body 502 and attract the electromagnet 503 .
[0038] It should be noted that, by utilizing the cooperation between the set ferromagnetic material 506 and the electromagnet 503, when current passes through, another un-energized ferromagnetic material 506 can be placed near the electromagnet 503. Due to the magnetic field generated by the electromagnet 503, the ferromagnetic material 506 will be magnetized, thereby becoming a temporary magnet, and generating attraction between it and the electromagnet 503. The ferromagnetic material 506 can be set to a metal such as iron, nickel or cobalt. However, when the electromagnet 503 is powered off, the magnetic field originally generated by the current will disappear. At this time, the electromagnet 503 no longer has magnetism and will not attract the ferromagnetic material 506.
[0039] In this embodiment, the two electromagnets 503 are electrically connected to the power supply inside the plug-in box 1 through wires.
[0040] It should be noted that, by utilizing the cooperation between the electromagnet 503 and the ferromagnetic material 506, when the plug-in box 1 is in operation, there will be current inside the plug-in box 1, which will be transmitted to the electromagnet 503 through the wire. The cabinet door 2 can be locked by the attraction between the electromagnet 503 and the ferromagnetic material 506. When the power is on, the set electromagnet 503 and the ferromagnetic material 506 can be used to open the cabinet door 2. Only when the power is off can the cabinet door 2 be opened.
[0041] The beneficial effects of the above embodiments are:
[0042] The padlock structure of the bus duct plug-in box can lock the cabinet door 2 through the attraction between the electromagnet 503 and the ferromagnetic material 506. When the power is on, the set electromagnet 503 and the ferromagnetic material 506 can be used to prevent the cabinet door 2 from being opened. Only when the power is off can the cabinet door 2 be opened. Therefore, only when the power is off can the cabinet door 2 be unlocked and opened, thereby preventing misoperation in the live state. The plug-in box body 1 is usually designed with a safety interlocking function, which can be achieved by the padlock component 5 to ensure that the plug-in box body 1 will not be opened by mistake when the power is on, thereby improving the safety of the device.
