Description

Technical Field

[0001] The utility model relates to the technical field of substations, and particularly relates to an outdoor box-type substation. Background Technique

[0002] A box-type substation is a compact complete power distribution device that combines high-voltage switchgear, distribution transformers, low-voltage switchgear, electric energy metering devices, reactive power compensation devices, etc. according to a certain wiring scheme. Compared with European box-type substations of the same capacity, the structure of American box-type substations is more reasonable. Since European box-type substations install transformers and ordinary high-voltage electrical equipment in the same metal shell box body, the temperature of the transformer room is very high, resulting in difficult heat dissipation and affecting the output. On the other hand, ordinary high-voltage load switches, fuses, and low-voltage switch cabinets are used in the box body, so European box-type substations are relatively large in volume. The structure of American box-type substations is different from that of European box-type substations. From the layout, its low-voltage room, transformer room, and high-voltage room are not arranged in a "mu" shape, but in a "pin" shape. From the structure, this box-type transformer is divided into two parts, the front and the back. The front part is the high- and low-voltage operation intervals, and the operation intervals include high- and low-voltage connection terminals, load switch operation handles, no-load voltage regulating tap switches, plug-in fuses, oil level gauges, etc. The rear part is the oil injection tank and heat sinks, and the transformer windings, iron cores, high-voltage load switches, and fuses are placed in the transformer oil tank.

[0003] However, it still has some disadvantages. For example, when installing an outdoor box-type substation, due to the heavy weight of the substation, its bottom is less fixed to the ground, which is likely to cause the substation to shake or even more serious situations during subsequent use due to some uncertain factors. Moreover, the substation is placed outdoors, where the outdoor temperature is high and the temperature of the internal transformer room is also very high, so it is difficult to dissipate heat inside the substation.

[0004] To solve the above problems, an outdoor box-type substation is proposed in this application. Content of the Utility Model

[0005] The purpose of the utility model is to provide an outdoor box-type substation to solve the problems of less fixed surface between the substation and the ground and heat dissipation of the substation in the prior art as mentioned in the above background technique.

[0010] Preferably, the fan frame is threadedly connected to the inner side of the chassis. The upper outer surface of the fan frame is fixedly connected to a fixing plate.
