Description
Technical Field
[0001] The utility model relates to the technical field of transformer substations, and more specifically, to a prefabricated box-type transformer substation with a rainproof function. Background Art
[0002] A prefabricated box-type substation is an electric power distribution equipment that integrates substation equipment and distribution equipment in one box. It has the characteristics of modular design and factory prefabrication, and can be quickly installed and put into use on site. A prefabricated box-type substation usually includes high-voltage equipment, low-voltage equipment, transformers, control systems, protection devices, etc., and can be used in power systems such as power supply, distribution and transformation. It has the advantages of compact structure, easy installation, reliable operation, and simple maintenance. It is suitable for various places, such as industrial areas, construction sites, mines, oil fields, urban complexes, etc. Prefabricated box-type substations have important application value in improving the reliability of power supply, saving space and cost, and shortening the construction period. Since the box-type transformer foundation is usually buried below the ground, this makes it easy for water to accumulate inside the foundation, which in turn affects the power supply and distribution safety of the box-type substation installed above it. This situation has become a problem that needs to be solved in the background technology.
[0003] At present, there are some inconveniences in the operation and maintenance of box-type substations in my country. Since box-type substations are usually used in outdoor environments, when it rains, operators need to carry out maintenance work in the rain, which not only affects the health of the operators, but also easily leads to safety accidents when working in the rain. Therefore, solving this problem has become a topic that needs to be tackled urgently in existing technologies.
[0004] Since the box-type substation contains high-power equipment such as transformers, a lot of heat will be generated, so effective ventilation and heat dissipation measures must be taken. In the prior art, a heat dissipation device is usually set on the outer shell of the box-type substation. The device includes a heat dissipation hole and a pressure plate outside the heat dissipation hole. The pressure plate is welded to the outside of the heat dissipation hole by spot welding. There is a gap between the two, so that the hot air inside the box-type substation is dissipated into the air through the gap. However, since these substations are often exposed to rain for a long time, there is a problem that rainwater may enter the box-type substation through the gap between the pressure plate and the heat dissipation hole. If a large amount of rainwater enters in a short time, it may cause a short circuit in the electrical components inside the substation, thereby causing unpredictable losses. Utility Model Content

[0009] The utility model is further configured that a convex platform is provided on the top of the middle block, and a concave platform is provided on the bottom of the top block, so that the installation process between the middle block and the top block is completed through the coordinated use of various components.

[0016] (III) Beneficial effects
[0017] Compared with the prior art, the utility model provides a prefabricated box-type substation with rainproof function, which has the following beneficial effects:
[0018] 1. Through the coordinated use of various components, the middle block can be easily stuck in the grooves around the base plate, making it more convenient to position during lifting. It can be positioned by simply facing the groove and falling into the groove. The outer edge side wall of the groove covers the outer side wall of the middle block, so that the joint gap between the two is located on the upper surface of the base plate. Compared with the joint gap located on the side or bottom of the base plate, this design makes the sealing between the middle block more convenient, and it is more convenient to perform sealing operations such as gluing and grouting in a limited working space, which effectively improves the reliability of the sealing.
[0019] 2. Through the coordinated use of various components, the design of heat dissipation holes, gusset plates and baffles allows hot air to be smoothly discharged into the air through the gaps in the heat dissipation holes, thus achieving heat exchange. This effectively dissipates the heat inside the substation, improves the heat dissipation efficiency, and ensures the normal working temperature of the substation. When it rains, rainwater entering the gaps in the gusset plates will be blocked by the baffles and flow downward along the baffles under the action of gravity, thereby ensuring that rainwater cannot enter the heat dissipation holes. This effectively prevents rainwater from entering the substation through the heat dissipation holes, thus avoiding possible losses and failures.
[0020] 3. The coordinated use of various components can effectively prevent rainwater from entering the substation and protect substation equipment from rain damage. The left slide and the right slide can move back and forth relative to each other. When performing maintenance on rainy days, you only need to pull the left slide and the right slide to both sides to form a canopy. In this way, the staff can perform maintenance work under the canopy to avoid working in the rain, reducing the possibility of safety accidents. BRIEF DESCRIPTION OF THE DRAWINGS
