Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a PT cabinet with a raised inspection and observation window. Background Art

[0002] PT cabinets (voltage transformer cabinets) are widely used in power systems, primarily in substations and power distribution scenarios, providing voltage measurement, protection, and isolation. With the development of power systems, the performance and safety requirements for PT cabinets are constantly increasing. However, traditional PT cabinet designs still have some shortcomings in terms of inspection and maintenance, which affect the safe operation of power systems.

[0003] Currently, most PT cabinet inspection windows are typically located at the bottom or center of the cabinet. This requires inspectors to bend or squat to check the cabinet's internal operating conditions during routine inspections, which is inconvenient and prone to fatigue. Furthermore, traditional inspection windows offer limited viewing angles, failing to provide multi-angle observation and preventing comprehensive monitoring of equipment operating status. This is particularly challenging in confined spaces, where blind spots are more likely to occur, increasing the risk of equipment failure.

[0004] Inspections of isolated phase busbars and their associated equipment primarily focus on hot spots at equipment connections, particularly the connection between the isolated phase busbar and the PT cabinet, typically located inside the PT cabinet's raised platform. Because the PT cabinet's raised platform is metal, routine inspections cannot directly view the operating status of the internal flexible connections through traditional observation windows. Inspections must be performed by disassembling the equipment during maintenance. This is not only time-consuming and labor-intensive, but also, due to the lack of timely observation methods, makes it difficult to detect potential faults, impacting equipment safety and the stable operation of the power system. Summary of the Invention

[0005] The purpose of the utility model is to provide a PT cabinet with a raised inspection and observation window to solve the problems mentioned in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides a PT cabinet with an elevated inspection observation window, comprising a cabinet body, a raised seat provided on the cabinet body, a through hole provided on one side of the raised seat, an observation window base provided inside the through hole, the observation window base being welded to the raised seat, an auxiliary box 1 provided on one side of the cabinet body, an auxiliary box 2 provided above the auxiliary box 1, box doors hinged on one side of the auxiliary box 1 and the box doors provided with handles.

[0007] Preferably, a mounting hole is provided on the observation window base, and the observation window is screwed into the mounting hole.

[0008] Preferably, a sealing gasket is provided between the observation window and the observation window base.

[0009] Preferably, the observation window is made of acrylic sheet.

[0010] Preferably, a lintel is provided at the top edge of the auxiliary box 2, and a secondary cable trough is provided at the top of the auxiliary box 2.

[0011] Preferably, a lightning arrester is provided in the auxiliary box 1, the lightning arrester is connected to a supporting insulator 1, and the supporting insulator 1 is connected to a connecting copper busbar.

[0012] Preferably, a voltage transformer is provided in the second auxiliary box, and a second supporting insulator is connected to the voltage transformer.

[0013] Preferably, the first supporting insulator and the second supporting insulator are connected via the connecting copper busbar.

[0014] Preferably, a wall bushing is provided at the bottom of the raising seat, and the bottom end of the wall bushing passes through the raising seat and the cabinet body in sequence and is connected to the connecting copper busbar.

[0015] Therefore, the utility model adopts a PT cabinet with an elevated inspection observation window of the above structure, which has the following advantages: during daily inspections, the crew members of the operation and maintenance can visually observe the status of the connection between the phase busbar and the PT cabinet through the preset observation window, thereby ensuring the reliable connection of the equipment conductor; the original structure is an integral metal structure, and the conductor connection status can only be checked after the connection structure is disassembled during shutdown and maintenance, which is not conducive to the timely discovery of hidden dangers in operation.
