Description

Technical Field

[0001] This utility model relates to the field of electronic power technology, specifically to a power protection device. Background Technology

[0002] As we all know, we use a large number of high-power electrical devices in our daily lives. Using these devices often carries the risk of overload. Overload not only affects the operation of the equipment but can also damage power lines and cause safety accidents such as fires. To address this issue, circuit breakers are now commonly used to solve electrical safety problems. When the current flowing through the power line is too high, the circuit breaker automatically disconnects the power line, thus achieving overload protection.

[0003] The aforementioned controllers (short-circuit protectors, residual current devices, circuit breakers, and other electrical components) used for circuit protection are typically installed in electrical control cabinets (electrical control boxes) to protect the controllers. However, existing electrical control cabinets that protect the controllers have a simple structure and suffer from the following shortcomings in practical use:

[0004] 1. The existing electrical control cabinet does not have multiple protection devices. When the circuit or controller fails, the maintenance personnel will directly open the cabinet door. If the controller explodes, sparks fly, or burns at this time, it will be dangerous for the maintenance personnel to open the cabinet door directly.

[0005] 2. When performing maintenance or wiring work on the controller inside the electrical control cabinet, the controller may explode or splinter, which can easily cause serious injury to the face of the personnel performing the maintenance. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] In view of the shortcomings of the existing technology, this utility model provides a power protection device that can better protect maintenance personnel.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a power protection device, including an electrical control cabinet, wherein the electrical control cabinet is equipped with several controllers and a cabinet door is installed on the electrical control cabinet, characterized in that: an adjustable baffle is installed inside the electrical control cabinet to provide protection, and the baffle is a transparent plate, and a fixing member is provided on the baffle for fixing the position of the baffle.

[0010] Furthermore, the fastener is a set screw that is threaded onto the baffle.

[0011] Furthermore, a fixing strip is fixedly installed inside the electrical control cabinet, and the fixing strip has several through holes that match the set screws.

[0012] Furthermore, the fastener is a pin that is slidably connected to the baffle.

[0013] Furthermore, the inner wall of the electrical control cabinet is provided with several sockets that match the plugs.

[0014] Furthermore, the outer wall of the electrical control cabinet is provided with a through groove for the baffle to pass through.

[0015] In addition, a handle is provided on the baffle.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a power protection device with the following advantages:

[0018] This power protection device features an adjustable and transparent baffle. When maintenance personnel open the electrical control cabinet, the baffle protects the inside of the cabinet. At this time, the personnel can observe the internal controller of the electrical control cabinet in detail through the baffle and make correct judgments. Alternatively, when it is certain that there will be no explosion, sparks, or other problems, the baffle can be opened to provide better protection for the maintenance personnel.

[0019] Furthermore, when inspecting and wiring the controller inside the electrical control cabinet, the position of the baffle can be adjusted so that it is positioned between the face of the maintenance personnel and the controller. Then, the personnel can pass their hands under the baffle to inspect the controller. In the event of an explosion, sparks, or other problems with the controller, the baffle will shield the face of the maintenance personnel, providing better protection and further improving safety.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] Please see Figure 1-7 This utility model discloses a power protection device, including an electrical control cabinet 1. The electrical control cabinet 1 is equipped with several controllers 3 for controlling the power of the circuit. The electrical control cabinet 1 is equipped with a cabinet door 2. A movable baffle 4 is installed inside the electrical control cabinet 1. A through groove 10 is opened on the outer wall of the electrical control cabinet 1 for the baffle 4 to pass through. The blocking position of the baffle 4 can be adjusted by moving the baffle 4. The baffle 4 plays a protective role. The baffle 4 is a transparent plate, so that the staff can pass through the baffle 4 to see the controllers 3 inside the electrical control cabinet 1. The baffle 4 is provided with a fixing member for fixing the position of the baffle 4.

[0030] The first fixed method, such as Figure 1 and Figure 2 As shown, the fixing component is a set screw 5 that is threaded onto the baffle 4. A fixing strip 6 is fixedly installed inside the electrical control cabinet 1. The fixing strip 6 is provided with several through holes 7 that match the set screw 5. The fixed position of the baffle 4 can be changed by inserting the set screw 5 into different through holes 7.

[0031] The second fixing method, such as Figure 3 and Figure 4 As shown, the fixing component is a pin 8 that is slidably connected to the baffle 4. The inner wall of the electrical control cabinet 1 is provided with several sockets 11 that match the pin 8. The pin 8 can be inserted into different sockets to change the fixed position of the baffle 4.

[0032] To facilitate the movement of the baffle 4, a handle 9 is provided on the baffle 4.

[0033] In summary, this power protection device, when in use, provides protection for the inside of the control cabinet 1 when maintenance personnel open the control cabinet 1. At this time, the personnel can observe the controller 3 inside the control cabinet 1 in detail through the baffle 4 to make correct judgments or to ensure that there will be no explosion, sparks, or other problems. When the controller 3 is being repaired or wired, the baffle 4 is adjusted to a suitable position and fixed with fasteners. The baffle 4 is positioned between the maintenance personnel's face and the controller 3, and then the personnel's hands pass under the baffle 4 to repair the controller 3. In the event of an explosion, sparks, or other problems with the controller 3, the baffle 4 will shield the maintenance personnel's face, providing better protection.
