Description

Technical Field

[0001] The utility model relates to the technical field of transformer oil tanks, in particular to a transformer oil tank structure with auxiliary cavity heat dissipation. Background Art

[0002] The transformer oil tank is a container for transformer oil, which has the functions of protecting, cooling and insulating the transformer. According to the size of the capacity, it can be divided into two basic types: box type (used for small and medium-sized transformers) and bell type (used for large transformers).

[0003] However, it still has the following disadvantages in actual use:

[0004] In the use of the existing transformer oil tank, heat is dissipated through multiple heat sinks arranged on the outer surface. However, when the load of the transformer is high, the heat dissipation efficiency of the heat sink is insufficient and cannot meet the heat dissipation demand of the transformer. Therefore, it is necessary to increase the transformer heat sink to dissipate heat and reduce the overall temperature of the transformer. The ordinary distribution transformer is a corrugated heat sink structure with a relatively simple structure. In order to ensure that the temperature rise of the transformer does not exceed the requirement when running under load, the heat dissipation area of ​​the heat sink needs to be increased. However, the length and width of the ordinary transformer oil tank cannot be too large due to cost issues, so the number of heat sinks will be limited. Utility Model Content

[0005] The utility model aims to provide a transformer oil tank structure with auxiliary cavity heat dissipation, so as to solve the problem raised in the above background technology that, in the use of the existing transformer oil tank, heat is required to be dissipated through multiple heat sinks arranged on the outer surface, but when the load of the transformer is high, the heat dissipation efficiency of the heat sink is insufficient and cannot meet the heat dissipation demand of the transformer.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a transformer oil tank structure with auxiliary cavity heat dissipation, comprising:

[0008] A transformer oil tank part, the transformer oil tank part comprising an oil tank body and side heat sinks;

[0009] The side cooling fins are fixed at equal distances to the middle of both sides of the oil tank body;

[0010] Add a heat dissipation unit, the heat dissipation unit includes an additional frame, an additional cavity, and an additional heat sink;

[0011] The mounting frame is symmetrically fixed to the front and rear ends of the side heat sinks, and the mounting cavity is opened in the middle of the outer side of the mounting frame, and the mounting heat sinks are equidistantly fixed in the mounting cavity.

[0012] Furthermore, guide grooves are equidistantly provided at the top and bottom ends of the interior of the installation cavity, and the interior width of the guide grooves is greater than the width of the installed heat sink.

[0013] Furthermore, the transformer oil tank portion also includes end heat sinks;

[0014] The end heat sinks are symmetrically and equidistantly fixed to the middle of the front and rear ends of the oil tank body.

[0015] Furthermore, it also includes a locking part, which includes a locking frame, a movable shaft, and a guide ball;

[0016] The locking frame is arranged in the middle of the lower end of the mounting frame, and the end of the movable shaft rotates in the middle of the upper end of the locking frame, and the guide balls are equidistantly sleeved in the middle of the movable shaft.

[0017] Furthermore, positioning blocks are fixed in the middle of both sides of the locking frame, and threaded holes extending into the lower ends of the two side walls of the lock mounting frame are opened in the middle of the positioning blocks.

[0018] Furthermore, guide openings are equidistantly provided at the upper parts of the front and rear ends of the locking frame, and the guide openings are arranged in the same manner as guide grooves.

[0020] The utility model installs a plurality of additional heat sinks in the installation frames at the front and rear ends of the side heat sinks, and sequentially increases the number of heat sinks on the outer surface of the oil tank body. Without changing the volume of the oil tank body, the heat dissipation effect of the oil tank body can be improved by increasing the number of heat sinks to meet the use requirements.

[0021] Based on the above beneficial effects, when installing the additional heat sink, the installation cavity used for installation is large in size, so the additional heat sink can be easily inserted and locked by external screws through the locking frame and the positioning blocks on both sides. At the same time, when the additional heat sink is placed in the installation cavity, it can be guided by guide balls to reduce the friction generated by the movement, save time and effort, and improve installation efficiency.

[0051] The guide opening 34 guides the installed heat sink 23 to the installation position;

[0052] Working principle: When multiple additional heat sinks 23 are installed in the installation cavity 22, the guide ball 33 on the locking frame 31 at the bottom contacts the lower end of the additional heat sink 23. Under the rolling action and in conjunction with the guide opening 34, the additional heat sink 23 can be quickly installed.

[0053] After the inner end of the heat sink 23 is in contact with the rear end of the inner wall of the cavity 22, the locking frame 31 can be moved upward, and the positioning block 35 can be used to cooperate with the threaded hole and the external screw to lock and fix it;
