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

[0019] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, and several embodiments of the utility model will be provided. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0020] For examples, please refer to Figure 1-5 This utility model provides a technical solution: A low-voltage switchgear designed to prevent misoperation includes a cabinet body 1. A cabinet door 2 is rotatably connected to the surface of the cabinet body 1 via a hinge. Heat dissipation vents 3 are provided at equal intervals on both sides of the cabinet body 1. Dust covers 4 are distributed at equal intervals on both outer walls of the cabinet body 1. An anti-misoperation and anti-touch panel 5 is provided on the front of the cabinet door 2. Locking components 6 for locking the cabinet door 2 are connected to the inner wall of the cabinet body 1 and the back of the cabinet door 2. The anti-accidental touch panel 5 includes an operation panel 501 disposed on the surface of the cabinet door 2. Fixed bases 502 are symmetrically disposed on both sides of the operation panel 501. The back of both fixed bases 502 are fixedly connected to the surface of the cabinet door 2. A protective cover 505 is disposed on the front of the operation panel 501. A T-shaped slide groove 503 is provided in the middle of the front of both fixed bases 502. A limit slide groove 504 is provided on the side of the front of both fixed bases 502 that is far apart from each other. The top of the two T-shaped slide grooves 503 respectively penetrates the top of the two fixed bases 502. A handle 507 is fixedly connected to the bottom of the front of the protective cover 505. T-shaped sliders 506 are symmetrically connected to both sides of the back of the protective cover 505. The two T-shaped sliders 506 are respectively adapted to the two T-shaped slide grooves 503. The two T-shaped sliders 506 are respectively engaged inside the two T-shaped slide grooves 503. The protective cover 505 is slidably connected to the fixed base 502 through the T-shaped sliders 506 and the T-shaped slide grooves 503. Limiting sliders 508 are fixedly connected to the bottom of both ends of the back of the two protective covers 505. The two limiting sliders 508 extend into the interior of the two limiting slide grooves 504 and are slidably connected to the interior of the two limiting slide grooves 504. The locking assembly 6 includes a connecting housing 601 disposed inside the cabinet 1. The outer wall of the connecting housing 601 is fixedly connected to the inner wall of one side of the cabinet 1. A connecting seat 602 is fixedly connected to one side of the back of the cabinet door 2. The height of the connecting seat 602 is higher than that of the connecting housing 601. An electromagnet 603 is connected to the bottom of the inner cavity of the connecting housing 601. A locking hole 604 is opened at the bottom of the connecting housing 601. A locking rod 605 passes through the top of the connecting housing 601. The top end of the locking rod 605 is inserted into the locking hole 604. A magnetic plate 606 is fixedly connected to the bottom of the locking rod 605. The magnetic plates 606 and 603 have opposite magnetic poles on the side that are close to each other. Guide rods 607 pass through both sides of the magnetic plate 606. The tops of the two guide rods 607 are fixedly connected to the top of the inner cavity of the connecting housing 601. A return spring 608 is sleeved on the outside of the end of the locking rod 605 located inside the connecting housing 601.

[0021] When the electromagnet 603 is energized, it generates magnetic force. Since the magnetic poles of the magnetic plate 606 and the electromagnet 603 are opposite on the side that are close to each other, the magnetic force generated by the electromagnet 603 repels the magnetic plate 606, causing the magnetic plate 606 to drive the locking rod 605 to move upward. The top of the locking rod 605 is inserted into the locking hole 604, realizing the automatic locking of the cabinet door 2, which can prevent the staff from opening the cabinet door 2 when the power is off at the network point. In this embodiment, the protective cover 505 is pulled upward by the handle 507. When the protective cover 505 rises to a certain height, the operation panel 501 is fully exposed, and the operator can easily operate the various switches on the operation panel 501. After the operation is completed, the handle 507 is released, and the protective cover 505 automatically slides down along the T-shaped slide groove 503 and the limiting slide groove 504 under its own weight until it covers the operation panel 501 again, thus playing a protective role against accidental touch.

[0022] The working process of this utility model is as follows: After closing cabinet door 2, the switch cabinet is powered on. When electromagnet 603 is energized, it generates magnetic force. Since the magnetic poles of magnetic plate 606 and electromagnet 603 are opposite on the side closest to each other, the magnetic force generated by electromagnet 603 repels magnetic plate 606, causing magnetic plate 606 to drive locking rod 605 upwards. The top of locking rod 605 inserts into locking hole 604, achieving automatic locking of cabinet door 2. This prevents staff from opening cabinet door 2 when the power is off. When cabinet door 2 needs to be opened, the switch cabinet is powered off, electromagnet 603 loses its magnetic force, and under the action of return spring 608, locking rod 605 moves downwards, its top end being pulled out of locking hole 604. At this time, cabinet door 2 can be opened. When staff need to operate the switches on the control panel 501, they can do so via handle 5. Pull the protective cover 505 upwards. The T-shaped slider 506 on the back of the protective cover 505 slides upwards along the T-shaped slide groove 503. The limiting slider 508 slides inside the limiting slide groove 504 to prevent the T-shaped slider 506 from detaching from the inside of the T-shaped slide groove 503. When the protective cover 505 rises to a certain height, the operation panel 501 is fully exposed, and the operator can easily operate the various switches on the operation panel 501. After the operation is completed, release the handle 507. Under its own weight, the protective cover 505 automatically slides down along the T-shaped slide groove 503 and the limiting slide groove 504 until it covers the operation panel 501 again, which plays a protective role against accidental touch. This design not only ensures that the operator can operate the switch smoothly, but also effectively avoids accidental touch, improving the safety and reliability of the switch cabinet.
