Description

Technical Field

[0001] This application relates to the field of equipment commissioning, and in particular to a protective tool for a pressure plate. Background Technology

[0002] Protection circuit breakers, also called protection connectors or trip circuit breakers, serve as the bridge and link between protection devices and external wiring, directly affecting the proper functioning of protection and its operational outputs. Based on their connection position to the secondary circuit of the protection device, they can be divided into two main categories: protection function circuit breakers and output circuit breakers. Protection function circuit breakers enable certain functions of the protection device (such as enabling or disabling main protection, distance protection, and zero-sequence protection), while output circuit breakers determine the outcome of the protection action. Depending on the object of the protection action output, they can be divided into trip output circuit breakers and initiation circuit breakers.

[0003] With the rapid development of the power industry, accidents in the secondary equipment circuits of power systems are becoming increasingly common. Many of these accidents stem from accidental closing of circuit boards, incorrect wiring, incorrect connection, incorrect short circuit, and accidental disconnection. This has led to a growing demand for safe and stable equipment operation. Particularly during the power plant's transition from infrastructure construction to production, the diverse and overlapping work environments on-site, including commissioning, maintenance, and operation personnel, pose a risk of unauthorized shutdowns of generating units and grid-connected equipment due to accidental activation of secondary safety measures. Therefore, the requirements for safe and stable equipment operation are even higher, and the need for effective solutions to address this situation is particularly urgent.

[0004] During the power plant's infrastructure construction to production phase, equipment inspection, and equipment modification phases, the on-site staff are diverse and there are many overlapping work areas. There is a risk that personnel from various parties, including commissioning, maintenance, and operation personnel, may accidentally activate the protection pressure plate, causing unauthorized shutdowns of operating units and grid-connected equipment. Utility Model Content

[0005] In order to make the pressure plate protection tool easy to operate, easy to install and disassemble, easy to identify and use, convenient, safe and reusable during equipment debugging, equipment inspection and equipment modification, this application provides a pressure plate protection tool.

[0006] This application provides a protective tool for pressure plates, which adopts the following technical solution:

[0007] A protective tool for pressure plates, comprising:

[0008] A protective cover is installed above the pressure plate;

[0009] Warning signs are placed on the protective cover;

[0010] At least one set of fixing components is provided, and the fixing components are provided on the side of the protective cover near the pressure plate.

[0011] By adopting the above technical solution, the protective cover is installed above the pressure plate, forming a physical barrier that effectively prevents personnel from accidentally touching the pressure plate during daily work. This avoids malfunctions or failures of the protection device due to accidental contact, thereby reducing the probability of equipment failures and power outages. Dust and moisture may affect the electrical performance of the pressure plate, leading to problems such as poor contact and reduced insulation. The protective cover can block dust and moisture from entering the pressure plate area. Warning signs on the protective cover constantly remind workers of the importance of protecting the pressure plate. These signs typically use eye-catching colors and text, such as red "Do Not Touch" or "High Voltage Danger," which can quickly attract attention and enhance workers' safety awareness. Warning signs can also be used to indicate the working or unworking status of the pressure plate. For example, "Working" and "Unworking" signs can be used to clearly indicate the current working status of the pressure plate. Fixing components are installed on the side of the protective cover closest to the pressure plate. At least one set of fixing components ensures that the protective cover is firmly installed on the pressure plate, preventing it from falling off when subjected to external impact or vibration, and ensuring that the protective cover can always perform its protective function.

[0012] Preferably, the pressure plate can be switched to an engaged state and an unengaged state, and the protective cover completely covers the pressure plate when the pressure plate switches states.

[0013] By adopting the above technical solution, when the pressure plate is switching states, the protective cover completely covers the pressure plate. When the state is switching, the operator may accidentally bump into the pressure plate or surrounding equipment. The protective cover can play a role in buffering and protecting the pressure plate from damage by external forces. For example, in some crowded equipment rooms, the operator may bump into other objects during operation. The protective cover can effectively protect the pressure plate from collision.

[0014] Preferably, the protective cover is provided with a fixing component near the edge of the pressure plate, or

[0015] The protective cover has at least one extension plate near the edge of the pressure plate, and the fixing component is mounted on the extension plate.

[0016] By adopting the above technical solution, a fixing component is installed at the edge of the protective cover near the pressure plate, which can make the protective cover more firmly fixed and effectively prevent it from loosening or falling off due to vibration, external impact, etc. during equipment operation. This ensures continuous protection of the pressure plate. When the pressure plate needs to be operated or maintained, the fixing component can be quickly removed, the protective cover can be taken off, and the protective cover can be reinstalled after the work is completed. The fixing component can make the fit between the protective cover and the pressure plate tighter, reduce gaps, and prevent dust, moisture, foreign objects, etc. from entering the pressure plate area, thus enhancing the protective effect of the pressure plate. The extension plate provides more installation position options for the fixing component. According to the actual situation, the fixing component can be installed in the most suitable position to achieve the best fixing effect. For example, for pressure plates of different shapes and sizes, the extension plate can adapt to various installation requirements, allowing the protective cover to better adapt to different equipment environments. The extension plate can change the shape and size of the protective cover to better adapt to different types of pressure plates and equipment layouts.

[0017] Preferably, the protective cover is shaped to fit the shape of the pressure plate, and an opening is provided on one side of the protective cover near the pressure plate.

[0018] By adopting the above technical solution, the protective cover's shape fits the pressure plate's outline, maximizing its coverage and reducing the gap between the cover and the pressure plate. This effectively prevents dust, moisture, and foreign objects from entering the pressure plate area, providing tighter protection. The fitted shape also makes the connection between the cover and the pressure plate more stable. The fitted cover has a neater and more aesthetically pleasing appearance, blending seamlessly with the overall equipment. The opening also facilitates observation of the pressure plate's status, such as its engagement or disengagement, indicator lights, etc., allowing for quick understanding of the pressure plate's operation without opening the cover.

[0019] Preferably, the opening of the protective cover is sized to accommodate the pressure plate in its withdrawn state, and the opening of the protective cover limits the position of the pressure plate.

[0020] By adopting the above technical solution, the opening size is large enough to accommodate the pressure plate in the retracted state, allowing operators to directly observe the pressure plate's status without removing the protective cover. This facilitates confirmation of whether the protection function is properly activated. Even when the pressure plate is in the retracted state, the protective cover still provides a certain level of protection. The opening limits the pressure plate, ensuring that it will not shift due to vibration, external forces, or other factors during equipment operation. When the pressure plate is subjected to external force, the limit at the opening prevents accidental activation and state switching.

[0021] Preferably, the fixing component is a magnetic suction device, which is installed on the side of the protective cover near the pressure plate, and the magnetic suction device installs the protective cover on the cabinet.

[0022] By adopting the above technical solution, the magnetic fastener, as a fixing component, makes the installation and removal of the protective cover more convenient. The operator only needs to bring the protective cover close to the cabinet, and the magnetic fastener will automatically attach to the cabinet. No tools are needed for complicated installation. Compared with traditional fixing methods (such as bolt fixing), the magnetic fastener will not damage the cabinet. The magnetic fastener is applicable to cabinets of various materials, including metal and plastic. Regardless of the material of the cabinet, as long as it can be attracted by the magnetic fastener, this fixing method can be used, which increases the applicability of the protective cover and improves its versatility.

[0023] Preferably, the warning sign is located on the side of the protective cover away from the pressure plate.

[0024] By adopting the above technical solution, the warning sign is placed on this side, which can attract people's attention at the first moment and let relevant personnel know the special status of the area or the pressure plate, thereby playing an effective warning role and avoiding safety accidents or equipment failures caused by misoperation or lack of awareness. The pressure plate may have certain position or shape changes in different states such as being put in or taken out, but by placing the warning sign on the outside of the protective cover, no matter what state the pressure plate is in, it will not obstruct or affect the display of the warning sign, ensuring that the warning information can always be clearly seen.

[0025] Preferably, the warning sign occupies at least 2 / 3 of the size of the side of the protective cover away from the pressure plate.

[0026] By adopting the above technical solution, the warning sign occupies at least 2 / 3 of the size of the protective cover away from the pressure plate, making the sign extremely prominent visually. Whether viewed from a distance or up close, it can quickly attract attention and improve the warning effect.

[0027] Preferably, the protective cover is made of fire-retardant insulating material.

[0028] By adopting the above technical solutions, various potential sources of ignition may exist in the electrical equipment environment, such as electric arcs caused by electrical faults and sparks generated by short circuits. The protective cover is made of fire-retardant materials, which can effectively prevent the spread of flames and reduce the possibility of fire. Once a fire occurs, the fire-retardant protective cover can reduce the damage to the protective pressure plate and surrounding equipment. Electrical equipment generates high voltage and strong electric field during operation. The protective cover is made of insulating materials, which can effectively prevent electric shock to personnel and short circuits in equipment.

[0029] Preferably, the protective cover is made of a transparent material.

[0030] By adopting the above technical solution, the transparent protective cover allows operators to directly observe the status of the protective pressure plate without opening the cover, including the pressure plate's engagement or disengagement status and the indicator light display. If the equipment is equipped with indicator lights, the transparent protective cover will not block the light from the indicator lights, ensuring that the indicator lights are always clearly visible. In some underground power distribution rooms or when operating at night, the transparent protective cover can ensure that the light from the indicator lights can pass through, allowing operators to clearly see the status of the protective pressure plate, thereby improving work safety and efficiency.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. The protective cover, positioned above the pressure plate, forms a physical barrier, effectively preventing accidental contact with the pressure plate during daily work. This avoids malfunctions or failures of the protective devices due to accidental contact, thus reducing the probability of equipment failures and power outages. Dust and moisture can affect the electrical performance of the pressure plate, leading to poor contact and reduced insulation. The protective cover prevents dust and moisture from entering the pressure plate area. Warning signs on the protective cover constantly remind workers of the importance of protecting the pressure plate. These signs typically use bright colors and text, such as red "Do Not Touch" or "High Voltage Danger," to quickly attract attention and enhance workers' safety awareness. Warning signs can also indicate the pressure plate's active or inactive status; for example, "Active" and "Inactive" labels can clearly indicate the current working status of the pressure plate. Fixing components are located on the side of the protective cover closest to the pressure plate. At least one set of fixing components ensures the protective cover is securely installed on the pressure plate, preventing it from falling off under external impact or vibration and ensuring that the protective cover always fulfills its protective function.

[0039] Explanation of reference numerals in the attached diagram: 1. Protective cover; 2. Warning sign; 3. Fixing component; 4. Extension plate. Detailed Implementation

[0040] The following is in conjunction with the appendix Figures 1 to 6 This application will be described in further detail.

[0041] This application discloses a protective tool for pressure plates. (Refer to...) Figures 1 to 3 The protective tool for the pressure plate includes a protective cover 1 covering the pressure plate, a warning sign 2 on the protective cover 1, and a fixing component 3 for mounting the protective cover 1 on the control panel. The pressure plate can be switched between an engaged and disengaged state. The protective cover 1, covering the pressure plate, forms a physical barrier, which can effectively prevent personnel from accidentally touching the pressure plate during daily work, avoiding malfunctions or failures of the protection device due to accidental contact with the pressure plate, thereby reducing the probability of equipment failure and power outages. Dust and moisture may affect the electrical performance of the pressure plate, leading to problems such as poor contact and reduced insulation. The protective cover 1 can block dust and moisture from entering the pressure plate area.

[0042] In an optional embodiment, the protective cover 1 completely covers the pressure plate when it undergoes a state transition. When the pressure plate transitions, the protective cover 1 completely covers it. During this transition, operators may accidentally bump into the pressure plate or surrounding equipment. The protective cover 1 acts as a buffer and protector, preventing damage to the pressure plate from external forces. For example, in crowded equipment rooms, operators may bump into other objects during operation; the protective cover 1 effectively protects the pressure plate from collisions. Optionally, the protective cover 1 is a square cover, as a square provides more space and can accommodate all states of the pressure plate; preferably, the protective cover 1 is square.

[0043] The fixing components 3 are located at the edge of the protective cover 1 near the pressure plate. When the protective cover 1 is square, optionally, two sets of fixing components 3 are provided, and the two sets of fixing components 3 are provided on two opposite sides of the protective cover 1; optionally, three sets of fixing components 3 are provided, and the three sets of fixing components 3 are respectively provided on three adjacent sides of the protective cover 1; optionally, four sets of fixing components 3 are provided, and the four sets of fixing components 3 are respectively provided on four sides of the protective cover 1; optionally, multiple sets of fixing components 3 are provided, and multiple fixing components 3 are provided on one side of the protective cover 1 at the same time.

[0044] Optionally, the protective cover 1 has at least one extension plate 4 near the edge of the pressure plate, and the fixing component 3 is installed on the extension plate 4. Providing the fixing component 3 near the edge of the protective cover 1 near the pressure plate allows for a more secure fixation of the protective cover 1, effectively preventing it from loosening or falling off during equipment operation due to vibration, external impact, or other reasons. This ensures continuous protection of the pressure plate. When operation or maintenance of the pressure plate is required, the fixing component 3 can be quickly released, the protective cover 1 removed, and the protective cover 1 reinstalled after the work is completed.

[0045] The fixing component 3 can make the fit between the protective cover 1 and the pressure plate tighter, reduce gaps, prevent dust, moisture, foreign objects and other objects from entering the pressure plate area, and enhance the protection effect of the pressure plate. The extension plate 4 provides more installation position options for the fixing component 3. According to the actual situation, the fixing component 3 can be installed in the most suitable position to achieve the best fixing effect. For example, for pressure plates of different shapes and sizes, the extension plate 4 can adapt to various installation requirements, so that the protective cover 1 can better adapt to different equipment environments. The extension plate 4 can change the shape and size of the protective cover 1 so that it can better adapt to different types of pressure plates and equipment layouts.

[0046] Reference Figures 4 to 6 In an optional embodiment, the protective cover 1 is shaped to fit the shape of the pressure plate, and an opening is provided on one side of the protective cover 1 closest to the pressure plate. The shape of the protective cover 1 fitting the shape of the pressure plate maximizes its coverage and reduces the gap between the protective cover 1 and the pressure plate. This more effectively prevents dust, moisture, and foreign objects from entering the pressure plate area, providing tighter protection for the pressure plate. The fitted shape also makes the connection between the protective cover 1 and the pressure plate more stable. The fitted protective cover 1 has a neater and more aesthetically pleasing appearance, integrating seamlessly with the overall equipment. The opening facilitates observation of the pressure plate's status, such as its engagement or disengagement status and indicator lights, allowing for quick understanding of the pressure plate's operation without opening the protective cover 1.

[0047] Optionally, the opening of the protective cover 1 is sized to accommodate the pressure plate in its retracted state, and the opening of the protective cover 1 limits the pressure plate. Even when the pressure plate is in the engaged state, the protective cover 1 still provides a certain degree of protection. The limiting effect of the opening on the pressure plate ensures that it will not shift due to vibration, external forces, or other factors during equipment operation. When the pressure plate is subjected to external forces, the limiting effect of the opening can transfer the force to the protective cover 1, thereby enhancing the stability of the protective cover 1.

[0048] Optionally, the fixing component 3 is a magnetic connector, which is installed on the side of the protective cover 1 near the pressure plate. The magnetic connector mounts the protective cover 1 onto the cabinet. Using the magnetic connector as the fixing component 3 makes the installation and removal of the protective cover 1 more convenient. If the cabinet is made of metal, the operator only needs to bring the protective cover 1 close to the cabinet, and the magnetic connector will automatically adhere to the cabinet, eliminating the need for complex installation using tools. Compared to traditional fixing methods (such as bolt fixing), the magnetic connector will not damage the cabinet. When the cabinet is made of plastic, each set of magnetic connectors consists of two parts, with the two parts respectively located on both sides of the cabinet, increasing the applicability of the protective cover 1 and improving its versatility.

[0049] When the pressure plate is in the engaged state, the protective cover 1 can completely cover the pressure plate in both the length and width directions. In a preferred embodiment, the two ends of the protective cover 1 in the length direction are arc-shaped to fit the shape of the pressure plate. Optionally, the length of the protective cover 1 is 2-3 mm greater than the length of the pressure plate, and the two ends of the protective cover 1 in the length direction are semi-circular arcs. In this case, the length of the protective cover 1 is the distance between the center points of the semi-circular arcs at both ends of the protective cover 1. In a preferred embodiment, the width of the protective cover 1 is 1-3 mm greater than the width of the pressure plate. If the width of the protective cover 1 is smaller within the error range, it fits the pressure plate better. If the width of the protective cover 1 is larger within the error range, the protective cover 1 can increase the accommodating space when covering the pressure plate. In a preferred embodiment, the height of the protective cover 1 is 1-3 mm greater than the pressure plate, and the opening size is set according to the swing range of the pressure plate when switching states. The opening can limit the pressure plate in the switching state.

[0050] In an optional embodiment, the warning sign 2 is positioned on the side of the protective cover 1 away from the pressure plate. Positioning the warning sign 2 on this side immediately attracts attention, allowing relevant personnel to quickly understand the special status of the area or the pressure plate, thus effectively warning against accidents or equipment malfunctions caused by misoperation or lack of awareness. While the pressure plate may change position or shape depending on its orientation (engaged or withdrawn), placing the warning sign 2 on the outside of the protective cover 1 ensures that it remains visible regardless of the pressure plate's state, guaranteeing the warning information is always clearly visible. Preferably, the warning sign 2 occupies at least 2 / 3 of the dimension of the side of the protective cover 1 away from the pressure plate. This makes the sign visually prominent, quickly attracting attention from both near and far views, thus enhancing the warning effect.

[0051] Optionally, the protective cover 1 is made of fire-retardant insulating material. The fire-retardant material effectively prevents the spread of flames and reduces the likelihood of a fire. In the event of a fire, the fire-retardant cover 1 can reduce the damage to the protective pressure plate and surrounding equipment. Preferably, the protective cover 1 is made of transparent material. The transparent cover 1 allows operators to directly observe the status of the protective pressure plate without opening it, including the pressure plate's engagement or disengagement status and indicator light displays. If the equipment has indicator lights, the transparent cover 1 will not block the light, ensuring the indicator lights are always clearly visible. In underground power distribution rooms or during nighttime operations, the transparent cover 1 ensures that the indicator lights can pass through, allowing operators to clearly see the status of the protective pressure plate, improving work safety and efficiency.

[0052] The implementation principle of this application embodiment is as follows: The protective cover 1 is installed above the pressure plate, forming a physical barrier that can effectively prevent personnel from accidentally touching the pressure plate during daily work, avoiding malfunction or failure of the protection device due to accidental contact with the pressure plate, thereby reducing the probability of equipment failure and power outage accidents; Dust and moisture may affect the electrical performance of the pressure plate, leading to problems such as poor contact and reduced insulation. The protective cover 1 can block dust and moisture from entering the pressure plate area; The warning sign 2 set on the protective cover 1 can constantly remind the staff of the importance of protecting the pressure plate. The warning sign 2 usually uses eye-catching colors and text, which can quickly attract attention and enhance the safety awareness of the staff; The warning sign 2 can also be used to indicate the engaged or disengaged status of the pressure plate; The fixing component 3 is set on the side of the protective cover 1 near the pressure plate. At least one set of fixing components 3 can ensure that the protective cover 1 is firmly installed on the pressure plate, which can prevent the protective cover 1 from falling off when subjected to external impact or vibration, ensuring that the protective cover 1 can always play its protective role.

[0053] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
