Description

Technical Field

[0001] The invention relates to the technical field of parallel cabinets, and in particular to a parallel cabinet based on high-voltage testing of gas generator sets. Background Art

[0002] The paralleling cabinet based on high-voltage testing of gas generator sets is mainly used for the parallel operation of multiple generator sets to achieve the reliability and flexibility of the power system. This paralleling cabinet not only needs to have basic parallel functions, but also needs to meet the requirements of high-voltage testing to ensure safety and performance stability under high-voltage conditions. The high-voltage test of gas generator sets involves evaluating the performance and safety of the generator set and its ancillary equipment under high-voltage conditions. High-voltage testing can ensure that it can work efficiently and safely in actual operation.

[0003] The patent publication number CN115498512A discloses a generator set parallel cabinet, which relates to the field of control cabinet technology. The cabinet body includes at least two or more first placement spaces for installing multiple generator set control elements. The first placement space is provided with multiple sets of mutually parallel and vertically distributed fixing bars, and several support plates are movably provided on the fixing bars. Slide blocks are provided on the support plates. Slide grooves for matching slide blocks are provided on the fixing bars along the Y-axis direction, and main busbars are movably supported on some support plates. This application uses the adjustable movable structure of the main busbar to perform a reasonable position layout to increase the installation distance between each main busbar, ensure circuit safety, and has great market promotion value.

[0004] The prior art has the following defects:

[0005] The high-voltage test module built into the parallel cabinet cannot be moved: The high-voltage test module is usually permanently fixed in the parallel cabinet during design. The parallel cabinet is tested at high voltage when repairing, upgrading or expanding the system. However, the high-voltage test module that cannot be moved lacks flexibility during use and maintenance, and is not convenient for adjusting the configuration or testing in different locations. When a fixed module fails, repair and replacement may require more time and effort, especially when operating in a small space. Therefore, it is necessary to set up a movable high-voltage test module to adapt to different testing requirements and operating scenarios, so as to improve the adaptability and scalability of the system.

[0006] Insufficient protection of the surrounding environment during high-voltage testing: A strong electromagnetic field will be generated during high-voltage testing, which will prevent surrounding electronic equipment from working properly. The electromagnetic field and heat generated by high-voltage testing will damage surrounding electronic equipment and appliances, leading to unpredictable production interruptions and maintenance costs. Sparks and arc discharges will also cause hidden dangers to the surrounding environment. Therefore, it is necessary to set up a deformable environmental chamber during high-voltage testing to isolate other equipment during high-voltage testing, so as to improve safety, equipment performance and work efficiency. Summary of the invention

[0007] In view of the problems in the prior art that the high-voltage test module built into the parallel cabinet cannot be moved and the protection capability of the surrounding environment during high-voltage testing is insufficient, a parallel cabinet based on high-voltage testing of gas generator sets is proposed.

[0008] The present application provides a parallel cabinet based on high-voltage testing of gas generator sets, the purpose of which is: through the provision of test components and main and auxiliary slide rail grooves, the test components can be moved arbitrarily in the protective shell, and high-voltage testing can be performed on any high-voltage cabinet, thereby achieving the effect of improving the adaptability and expansibility of the system; through the provision of protection components and push-pull rails, the protection components can be moved to protect any high-voltage cabinet while performing high-voltage testing, thereby achieving the effect of improving safety, equipment performance and work efficiency.

[0009] The technical solution of the present invention is: a parallel cabinet based on high-voltage testing of gas generator sets, comprising a housing assembly, a test assembly arranged inside the housing assembly, a protection assembly and a plurality of high-voltage cabinets, a control cabinet arranged on one side of the housing assembly, an operating door arranged behind the housing assembly, and a plurality of steering assemblies respectively arranged between the housing assembly and the test assembly, and between the housing assembly and the protection assembly, wherein the housing assembly comprises a protective housing;

The main slide rail groove is connected to multiple auxiliary slide rail grooves in the same plane, and the two main slide rail grooves are respectively arranged at the top and bottom of the test component and the protection component.

[0011] By adopting the above scheme, the high-voltage cabinet that needs high-voltage testing is called out from the protective shell. When the outermost high-voltage cabinet needs to be tested, it is only necessary to vacate the position of the high-voltage cabinet close to the control cabinet.

[0021] By adopting the above scheme, the cabinet body is pushed on the push-pull track by operating the pushing rod, and the pressure-resistant pulleys at the top and bottom of the cabinet body slide in the push-pull track, and the cabinet body moves accordingly. When the outermost high-voltage cabinet needs to be inspected, it is only necessary to vacate the position of the high-voltage cabinet close to the control cabinet. When the high-voltage cabinet in the middle position or close to the control cabinet needs to be inspected, it is necessary to vacate the positions on both sides of the high-voltage cabinet.

[0022] Furthermore, ventilation chute grooves are provided on both sides of the protective shell, and a plurality of wire inlet grooves are provided on the inner wall of the protective shell.

[0047] By calling out the high-voltage cabinet 2 that needs high-voltage testing in the protective casing 11, when the outermost high-voltage cabinet 2 needs to be tested, it is only necessary to vacate the position of the high-voltage cabinet 2 close to the control cabinet 3; when the high-voltage cabinet 2 in the middle or close to the control cabinet 3 needs to be tested, it is necessary to vacate the positions on both sides of the high-voltage cabinet 2, and move the test component 5 and the protection component 6 into the vacated positions. The high-voltage test cabinet 51 is pushed into the empty space on one side of the high-voltage cabinet 2 to be tested through the steering component 7 connected at the upper and lower ends through the main slide rail groove 14 and the auxiliary slide rail groove 15 to adapt to different testing requirements and operating scenarios, so as to improve the adaptability and expansibility of the system.
