Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of transformer technology, and in particular to an oil-immersed transformer base. Background Technology

[0002] As a core device in the power system that changes voltage and ensures stable power transmission, the performance and adaptability of transformers directly affect power supply efficiency and safety. In actual operation and maintenance, for emergency repairs during unplanned power outages, users often need to use transformers from the manufacturer's inventory. However, there are the following drawbacks in replacing inventory transformers: (1) The concrete base of the transformer room is fixed and cast. Its length, width, height and the distance between the bases are fixed. If the newly replaced transformer base does not match the concrete base, the transformer base needs to be modified. (2) The height and position of the high and low voltage cables in the transformer room are fixed. If the height of the newly replaced transformer differs greatly from that of the cable, the cable needs to be extended or the cable needs to be rearranged.

[0003] The above-mentioned defects will undoubtedly significantly extend the replacement cycle of transformers, which contradicts the user's demand for high efficiency. Therefore, a new transformer base is needed to solve the defects of replacing transformers during unplanned power outages. Utility Model Content

[0023] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0024] See Figure 1 , Figure 1This is a schematic diagram of an oil-immersed transformer base according to an embodiment of the present invention. It includes a transformer oil tank and an adjusting rail base. The adjusting rail base includes a fixed rail base 110 and a sliding rail base 120. The sliding rail base 120 is slidably connected to the fixed rail base 110. The bottom of the fixed rail base 110 is provided with a groove 111, and the upper part of the sliding rail base 120 is connected with a boss 121 that cooperates with the groove 111. The sliding rail base 120 can slide relative to the fixed rail base 110 along the length direction through the boss 121.

[0025] In one feasible embodiment, such as Figure 2 As shown, a limiting hole 210 is provided at the end of the slide groove 111. The adjusting rail seat also includes a limiting component, which is connected to the fixed rail seat 110 through the limiting hole 210. Its function is to limit the sliding stroke of the sliding rail seat 120 on the fixed rail seat 110 and prevent the sliding rail seat 120 from slipping off the fixed rail seat 110, thereby ensuring the stability of the connection between the sliding rail seat 120 and the fixed rail seat 110.

[0026] In one feasible embodiment, such as Figure 3 As shown, the limiting component includes a limiting member 310 and a first fastener. The limiting member 310 has a through hole 311 corresponding to the position of the limiting hole 210. The first fastener passes through the through hole 311 and the limiting hole 210, thereby connecting the limiting component to the fixed rail 110. Specifically, the limiting member 310 can be connected to the limiting hole 210 by bolting or binding, thereby achieving a fixed connection with the fixed rail 110.

[0027] In one feasible embodiment, the first fastener includes a first bolt and a first nut; one end of the first bolt passes through the through hole 311 and the limiting hole 210 in sequence, and then is screwed into the first nut for fixation. The connection method of using a bolt and nut for screwing in not only provides a stable connection, but also facilitates disassembly and assembly operations.

[0028] In one feasible embodiment, the first fastener can be a binding member, which consists of a first fastening band and a buckle; the first fastening band passes through the through hole 311 and the limiting hole 210 in sequence, and then locks and fixes itself with the buckle. The binding member provides a more flexible connection method, and the connection can be completed quickly without the need for tools.

The adjusting rail seat also includes a connecting component, which is connected to the transverse gauge hole 220 and the connecting hole 410 respectively, so that the fixed rail seat 110 and the sliding rail seat 120 are fixed to each other. This allows the sliding rail seat 120 to be firmly fixed to the fixed rail seat 110 after it is adjusted to a suitable position.

[0030] In one feasible embodiment, such as Figure 5 As shown, the connecting assembly includes a connector 510 and a second fastener. One side of the connector 510 has a first transverse opening 511 corresponding to the transverse gauge hole 220, and the other side has a second transverse opening 512 corresponding to the connecting hole 410. The second fastener, the transverse gauge hole 220, the first transverse opening 511, the connecting hole 410, and the second transverse opening 512 cooperate to fix the connector 510 to the sliding rail seat 120. Through the combined use of the connector 510 and the second fastener, a reliable connection between the fixed rail seat 110 and the sliding rail seat 120 can be achieved, enhancing the stability of the overall structure.

[0031] In one feasible embodiment, the second fastener includes at least a first bolt fastening assembly 610 and a second bolt fastening assembly 620. The first bolt fastening assembly 610 includes a first bolt and a first nut, and the second bolt fastening assembly 620 includes a second bolt and a second nut. The first bolt passes through the first transverse opening 511 and the transverse gauge hole 220 and is screwed onto the first nut, fixing the connector 510 to the fixed rail seat 110. The second bolt passes through the second transverse opening 512 and the connecting hole 410 and is screwed onto the second nut, fixing the connector 510 to the sliding rail seat 120. During assembly, first, the first bolt is passed through the first transverse opening 511 and the transverse gauge hole 220, then the first nut is screwed on and tightened. Subsequently, the second bolt is passed through the second transverse opening 512 and the connecting hole 410, the second nut is screwed on and tightened, thus completing the fixing of the connector 510 to the fixed rail seat 110 and the sliding rail seat 120. The assembled structure is as follows. Figure 6 As shown, this enables a stable connection between the fixed rail base 110 and the sliding rail base 120, ensuring that the transformer is securely installed.

[0032] In one feasible embodiment, the second fastener includes at least a first binding assembly and a second binding assembly. The first binding assembly includes a first binding strap and a first buckle, and the second binding assembly includes a second binding strap and a second buckle. The first binding strap passes through the first transverse opening 511 and the transverse gauge hole 220 and then engages with the first buckle to fix the connector 510 to the fixed rail seat 110. The second binding strap passes through the second transverse opening 512 and the connecting hole 410 and then engages with the second buckle to fix the connector 510 to the sliding rail seat 120.

[0033] In one feasible embodiment, such as Figure 7 As shown, a longitudinal gauge hole 710 is provided on the bottom plate of the sliding rail seat 120. The longitudinal gauge hole 710 is used to connect with the concrete base of the transformer room, so as to facilitate the fixing of the sliding rail seat 120 to the concrete base.

[0034] In one feasible embodiment, the boss 121 is structured as follows: Figure 8 As shown, it is adapted to the shape of the slide groove 111, and can slide smoothly in the slide groove 111, while ensuring the stability of the connection between the sliding rail seat 120 and the fixed rail seat 110, and avoiding jamming or shaking during the sliding process.

[0035] It should be noted that this utility model does not limit the number or size of holes in each component, as long as the components can be assembled in a corresponding manner and the assembled structure is safe, sturdy and usable.
