[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The embodiments described in this application are only part of the embodiments of the utility model, not all of them. Based on the spirit of the utility model, other embodiments obtained by ordinary technicians in this field without creative work are all within the scope of protection of the utility model.

[0024] The utility model provides a casting positioning structure for fixing an oil-immersed reactor body, comprising a positioning nail 1, a positioning bowl 2 and a casting positioning component.

[0025] The positioning nail 1 and the positioning bowl 2 are respectively arranged at fixed positions inside the oil-immersed reactor body and the oil tank; the positioning nail 1 is fixedly inserted into the positioning bowl 2;

[0026] The casting positioning assembly includes a laminated wood positioning bowl 3, a support bar 4 and an epoxy resin 5. The laminated wood positioning bowl 3 and the support bar 4 are placed between the positioning nail 1 and the positioning bowl 2. The epoxy resin 5 is cast between the positioning nail 1 and the laminated wood positioning bowl 3 to form a fixation.

[0027] In a preferred but non-limiting embodiment of the utility model, the height of the support bar 4 is consistent with the height of the laminated wood positioning bowl 3, the positioning bowl 2 and the laminated wood positioning bowl 3 are both cylindrical structures with an open upper end, and the diameter of the positioning bowl 2 is larger than that of the laminated wood positioning bowl 3.

[0028] like Figure 1 , Figure 2 As shown, during the assembly process, firstly, a laminated wood positioning bowl 3 is placed in the positioning bowl 2, and four stays 4 are used between the two layers of positioning bowls for reinforcement. Before the reactor body is lowered into the box, epoxy resin 5 casting material is poured into the laminated wood positioning bowl, and the positioning pins 1 at the bottom of the reactor body are inserted into the positioning bowl 2. In this way, the epoxy resin casting material can completely fill the gap between the laminated wood positioning bowl and the positioning pins, thereby better fixing the reactor body.

[0029] In a preferred but non-limiting embodiment of the present invention, the outer circumference of the laminated wood positioning bowl 3 is provided with four grooves evenly distributed along the circumference for accommodating the support bars 4 .

[0030] The positioning bowl 2, the support bar 4 and the pressed wood positioning bowl 3 are structurally fixed by matching their sizes. When the device body needs to be lifted out of the oil tank, the support bar can automatically fall off as the device body is lifted, making it convenient to check the product's hanging core.

[0031] Further preferably, the entire casting positioning structure is formed at multiple locations between the device body and the oil tank, and each casting positioning structure is cured at the same time, so that the device body and the oil tank become a whole, thereby achieving good fixation of the device body.

[0032] The beneficial effect of the utility model is that, compared with the prior art,

[0033] 1) The utility model changes the traditional fixing structure, removes the opening of the core clamp, welds the positioning pins and the positioning bowl on the clamps and the oil tank of the reactor, and pours the epoxy resin casting material into the laminated wood positioning bowl before the reactor body is placed in the oil tank. When the reactor body is placed in the oil tank, the positioning pins are inserted into the positioning bowl, and the epoxy resin casting material completely fills the gap between the laminated wood positioning bowl and the positioning pins. After drying and curing, the epoxy resin can become a rigid body with high mechanical strength and stable chemical properties. It can be used in the oil tank without affecting the normal operation of the product. The reactor body and the oil tank are cast as a whole, making the oil-immersed reactor safer during transportation, and the product performance is not affected by the displacement of the reactor body, and the reactor has better integrity;

[0034] 2) The utility model provides an oil-immersed reactor body and oil tank that are integrated into one unit. This improvement makes the oil-immersed reactor more stable and reliable during transportation. This optimized design is expected to further enhance the safety and reliability of the reactor.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or replaced by equivalents, and any modifications or equivalent replacements that do not depart from the spirit and scope of the utility model should be included in the scope of protection of the claims of the utility model.
