Description

Technical Field

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

[0002] Switchgear is a relatively mature electrical peripheral facility, used in a wide range of locations, including indoors and outdoors, such as bridges and railroad tracks. Current switchgear doors often feature observation windows to facilitate observation of the operating status of internal electrical components. However, high-voltage switchgear used in key locations, such as highways and around railroad tracks, is subject to occasional splashing of debris, which can shatter the observation window and necessitate replacement. Currently, metal mesh is installed within the observation window to enhance its strength. However, the addition of metal mesh can increase the difficulty of replacing the glass.

[0019] The beneficial effects of the utility model are as follows:

[0020] The utility model can ensure the sealing performance of the high-voltage switch cabinet even if any one layer of glass is broken by the other layer of glass. At the same time, when maintenance is needed, the frame cabinet door can be directly removed and replaced with a frame with two complete layers of glass, which saves the efficiency of replacement. The frame with broken glass can be returned to the factory for unified processing, thereby improving maintenance efficiency.

[0021] In order to more clearly illustrate the structural features and functions of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0027] like Figure 1-Figure 2 As shown, in one embodiment, a high-voltage cabinet door 7 observation window specifically includes:

[0028] Frame 1, which serves as the mounting structure for glass 2, is removably fixed to the corresponding position of cabinet door 7. The shape of frame 1 is not limited here and can be selected according to actual needs. A rectangular frame 1 structure is preferably used. Bolt holes 3 are provided on both sides of the edge of frame 1, allowing installation at the corresponding position of cabinet door 7 from the inside. The contact area between frame 1 and cabinet door 7 is filled with sealing strips to ensure overall sealing.

[0029] At least two layers of glass 2 are secured within the frame 1. The glass 2 is arranged parallel to each other, and a metal mesh 4 is disposed within each glass 2. The metal mesh 4 enhances the strength of the glass 2 and effectively eliminates static electricity when the metal mesh 4 is grounded. It should be noted that each layer of glass 2 can be composed of two stacked glass sheets, with the metal mesh 4 sandwiched between the two sheets.

[0030] In summary, after any layer of glass 2 is broken, the other layer of glass 2 can still ensure the sealing performance of the high-voltage switch cabinet. At the same time, when maintenance is needed, the cabinet door 7 of the frame 1 can be directly removed and replaced with the frame 1 with two complete layers of glass 2, which saves more replacement efficiency. The frame 1 with broken glass 2 can be returned to the factory for unified processing, thereby improving maintenance efficiency.

[0031] In some preferred embodiments, the gap 5 is filled with protective gas, such as argon or krypton, which can improve the heat insulation or sound insulation performance of the entire observation window. Specifically, an air filling hole 6 is provided on the side of the frame 1, through which the protective gas can be filled into the gap 5, and the plug is plugged into the air filling hole 6 to prevent air leakage. Furthermore, a pressure sensor can also be installed in the gap 5, specifically on the inner wall surface of the frame 1. The pressure sensor is electrically connected to the electrical components in the switch cabinet. When any layer of glass 2 is broken, the protective gas in the gap 5 leaks, thereby reducing the pressure to a certain threshold. The pressure sensor transmits a signal to the corresponding alarm, and the alarm can be transmitted to the remote control center through the network to detect the breakage more promptly and to carry out repairs and replacements in time. It should be noted that the pressure monitoring and signal transmission of the pressure sensor are mature existing technologies and will not be elaborated here.

[0032] In some preferred embodiments, the frame 1 may be made of high-strength plastic or metal material, wherein the high-strength plastic is polycarbonate or polyamide.

[0033] like Figure 3 As shown, the present application provides a high-voltage cabinet, which includes a cabinet door 7, on which is mounted at least one observation window as described above, and a cabinet body 8;

[0034] In this embodiment, two observation windows are installed, one of which is installed at the upper part of the cabinet door 7 and the other is installed at the lower part of the cabinet door 7, so that the situation inside the high-voltage cabinet can be observed from more angles.

[0035] In some other preferred embodiments, an observation window may be installed on the cabinet door 7 so that the conditions inside the high-voltage cabinet can be observed from more angles.

[0036] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
