Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a housing for testing a transformer development platform. Background Technology

[0002] Transformers are typical electromagnetic devices. In transformer design and manufacturing, the transformer windings are generally fixed to the iron core, forming a single unit. This unit is then placed in the transformer enclosure, where heat dissipation devices, conductive rods, and insulators are installed. During transformer development and testing, the windings and iron core typically require adjustments to meet requirements related to temperature rise, partial discharge, weight, volume, and cost. This necessitates different transformer test enclosures to assemble the iron core and windings. However, transformer enclosures are generally of fixed dimensions. In transformer development and testing, different enclosures need to be custom-made according to the varying dimensions of the windings and iron core. This results in low utilization of test angles of different sizes and high testing costs.

[0003] Therefore, it is necessary to provide a housing for testing a transformer development platform to solve the above-mentioned technical problems. Utility Model Content

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0031] like Figure 1-6 As shown, the housing for testing a transformer development platform provided by this utility model includes: at least four side plates 1 and at least two end plates 2. The four side plates 1 are fixedly spliced ​​into a rectangular cylindrical structure. The two end plates 2 are respectively fixed to both ends of the rectangular cylindrical structure composed of the four side plates 1, forming a closed transformer test box. A first fixing frame 4 is provided on one side of each side plate 1. The first fixing frame 4 is integrally formed with the side plate 1. Multiple through holes 5 are provided around the first fixing frame 4. Multiple threaded holes 6 are symmetrically provided on the two sides of the side plate 1 away from the first fixing frame 4. When two side plates 1 are expanded on a plane, that is, when two side plates 1 are connected to form a larger side plate, the two side plates 1 are first aligned end to end to make the two side plates contact each other. Then, multiple bolts are passed through the through holes 5 on the two first fixing frames 4 and fixed with nuts to achieve the fixation of the two side plates 1 (e.g., ...). Figure 1 As shown), when the two side plates 1 are installed vertically, the bolts pass through the corresponding through holes 5 and are threaded into the corresponding threaded holes 6 (as shown). Figure 1As shown, a second fixing frame 7 is provided on one side of the end panel 2. The second fixing frame 7 is integrally formed with the end panel 2. Multiple through holes 5 are also provided around the second fixing frame 7. Multiple threaded holes 6 are provided on the four sides of the end panel 2 away from the second fixing frame 7. When the end panel 2 is fixed to the rectangular cylindrical structure composed of four side panels 1, the bolt is passed through the through hole on one side of the first fixing frame 4 and threaded to the threaded hole 6 on the end panel 2, thereby fixing the end panel 2 to the side panel 1. When the end panel 2 needs to be expanded, the bolt is passed through the through hole on two contacting second fixing frames 7 and fixed with a nut, thereby expanding the end panel 2. This device can splice transformer test boxes of different sizes by changing the number of side panels 1 and end panels 2. It does not require the customization of boxes of specific sizes, making it more flexible in use. Only basic materials such as side panels 1 and end panels 2 are needed to change the size, making it more economical.

[0032] Furthermore, at least one of the side plates 1 has a plurality of fixing holes 9, and an insulating terminal 11 is installed in the fixing holes 9. The insulating terminal 11 is used to connect the high-voltage power supply and the winding for testing.

[0033] At least one of the side plates 1 has multiple threaded mounting holes 10. The threaded mounting holes 10 are used to install auxiliary devices for transformer testing (such as sensors, exhaust components for vacuuming, etc.). The threaded mounting holes 10 are also equipped with sealing screws 12, which are used to seal the threaded mounting holes 10.

[0034] Furthermore, it also includes at least one intermediate plate 3. During the expansion of the transformer test box, when the end panel assembly consisting of only multiple end panels 2 cannot meet the size requirements, i.e., when it needs to be expanded in the Z-axis direction, at least one intermediate plate 3 is required. A third fixing frame 8 is provided on one side of the intermediate plate 3. The third fixing frame 8 has multiple through holes 5. Through the multiple through holes 5 and with the cooperation of bolts and nuts, the third fixing frame 8 can be fixed with the corresponding second fixing frame 7 and the corresponding third fixing frame 8, thereby realizing the expansion of the end panel assembly. Multiple threaded holes 6 are provided on both sides of the side of the intermediate plate 3 away from the third fixing frame 8. By passing the bolt through the through holes 5 on the first fixing frame 4 and threading it through the threaded holes 6 on the intermediate plate 3, it can be fixed with the side plate 1.

[0035] In this application, sealing rings or sealing strips are used to seal all the parts connecting side plate 1 to side plate 1, side plate 1 to end panel 2, end panel 2 to end panel 2, end panel 2 to intermediate plate 3, intermediate plate 3 to intermediate plate 3, and intermediate plate 3 to side plate 1, so as to achieve the overall sealing of the transformer test box.

[0036] Furthermore, at least one end panel 2 is provided with an observation hole 13, which is made of tempered laminated glass. The observation hole 13 is provided to facilitate personnel to observe the internal situation of the enclosure.

[0037] In this application, the first fixing frame 4, the second fixing frame 7, and the third fixing frame 8 have the same thickness but different lengths and widths, and the opening positions of the perforations 5 are corresponding, which facilitates the connection between different boards.
