Description

Technical Field

[0001] The utility model relates to the field of electrical cabinets, in particular to an observation window applied to a high-voltage electrical cabinet. Background Art

[0002] An electrical cabinet is an electrical equipment with the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, no site restrictions, wide application, stable and reliable operation, high space utilization, small footprint and environmental protection. Many electrical cabinets are equipped with observation windows to observe the internal situation and perform maintenance and adjustments in time.

[0003] Although the existing observation window can observe the situation inside the electrical cabinet, when it is necessary to use a temperature measuring device to measure the temperature of the copper bar in the cabinet and check whether it is energized, the observation window cannot be opened because it is fixedly installed. Therefore, it is necessary to open the electrical cabinet door or remove the sheet metal shell before operation, which is very inconvenient. Therefore, the utility model proposes an openable observation window. Summary of the invention

[0004] The utility model provides an observation window applied to a high-voltage electrical cabinet to solve the problems mentioned in the above background technology.

[0005] The purpose of the utility model is achieved by the following methods:

[0006] An observation window used in a high-voltage electrical cabinet comprises a frame body, one end of which is provided with a receiving groove, a slidably matched transparent plate is installed in the receiving groove, and one end of the transparent plate is provided with a retaining edge.

[0007] Furthermore, the frame is provided with a positioning pin for fixing the transparent plate, and the transparent plate is provided with a positioning hole for cooperating with the positioning pin.

[0008] Furthermore, a sealing gasket is provided on one side of the frame, and a sealing ring is provided at the lower end of the retaining edge.

[0009] Furthermore, a limiting groove is provided in the accommodating groove.

[0010] Furthermore, a lifting handle is provided at one end of the transparent plate.

[0011] Furthermore, a hook is provided at one end of the frame.

[0012] The beneficial effects of the utility model are as follows: a receiving groove is provided at one end of the frame, and a slidably matched transparent plate is installed in the receiving groove. It is possible to use a temperature measuring device to measure the temperature of the copper bar in the cabinet by simply pulling out the transparent plate. This improves the practicality and convenience of the observation window. At the same time, the ribs limit the transparent plate in the receiving groove, making it more closely fit the surface of the frame. This improves the aesthetics of the observation window.

DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] Embodiment 1:

[0019] In this embodiment, refer to Figure 1-Figure 3 The specific implementation of the observation window for high-voltage electrical cabinets includes a frame 1, a receiving groove 2 is provided at one end of the frame 1, a transparent plate 3 is installed in the receiving groove 2, and a rib 10 is provided at one end of the transparent plate 3. The frame 1 is fixed to the surface of the electrical box by screws, and the installation is convenient and quick, so that the temperature of the copper bar in the cabinet can be measured by a temperature measuring device by pulling out the transparent plate 3. The rib 10 limits the position of the transparent plate 3 and makes it fit the surface of the frame 1 more closely.

[0020] Furthermore, the frame 1 is made of a wear-resistant and high-hardness plastic material in one piece, which increases the service life and stability of the observation window. The transparent plate 3 is made of a high-transparency glass material so that the internal situation can be clearly observed.

[0021] Furthermore, the frame 1 is integrally formed with a plurality of reinforcing ribs, which make the frame 1 more stable and durable, effectively improve the load-bearing capacity and compression resistance of the observation window, and ensure safe use.

[0022] Furthermore, the frame 1 is provided with a positioning pin 4 for fixing the transparent plate 3, and the transparent plate 3 is provided with a positioning hole 5 for cooperating with the positioning pin 4. Through the cooperation between the positioning pin 4 and the positioning hole 5, the transparent plate 3 is firmly confined in the receiving groove 2.

[0023] Furthermore, a limiting groove 6 is provided in the receiving groove 2. The limiting groove 6 makes the transparent plate 3 smoother and more stable during the sliding process, prevents the transparent plate 3 from shaking, and improves the user experience of the observation window.

[0024] Furthermore, a lifting handle 7 is provided at one end of the transparent plate 3, so that the transparent plate 3 can be taken out more conveniently when the transparent plate 3 needs to be replaced, thereby improving the convenience of replacement.

[0025] Further, one end of the frame 1 is provided with a hook 8. The hook 8 can conveniently hang some tools or small items, such as maintenance diaries, inspection tables and other items, thereby increasing the practicality of the observation window.

[0026] The beneficial effects of the utility model are as follows: a receiving groove 2 is provided at one end of the frame 1, and a slidably matched transparent plate 3 is installed in the receiving groove 2. It is possible to use a temperature measuring device to measure the temperature of the copper bar in the cabinet by simply pulling out the transparent plate. This improves the practicality and convenience of the observation window. At the same time, the retaining edge 10 allows the transparent plate 3 to be limited in the receiving groove 2, and to fit the surface of the frame 1 more closely. This improves the aesthetics of the observation window.

[0027] Embodiment 2:

[0028] like Figure 4 As shown, the difference between this embodiment and the first embodiment is that a sealing gasket 9 is provided on one side of the frame 1, and a sealing ring 11 is provided at the lower end of the retaining edge 10. The sealing gasket 9 and the sealing ring 11 make the observation window as a whole sealed, which has the effect of dustproof and waterproof.

[0029] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiments according to the technology of the utility model, which does not depart from the content of the technical solution of the utility model, belongs to the scope of the technical solution of the utility model.
