Description

A New Air Heat Exchange Cooling Substation

technical field

The utility model relates to the field of substations, in particular to a novel air heat exchange cooling type substation.

Background technique

A substation is a place where voltage is changed. In order to transmit the electric energy from the power plant to a distant place, the voltage must be raised to become high-voltage electricity, and then the voltage is lowered as needed near the user. This work of raising and lowering the voltage is done by the substation. The main equipment of substations are switches and transformers. In order to meet the needs of safety and management, most of the existing substations are closed or semi-closed spaces, and the existing closed or semi-closed substations are ordinary small houses with windows or large cabinets.

Because a large number of electrical components are usually installed inside the cabinet to work normally, these electrical components will generate a lot of heat when they work. In order to keep the temperature in the cabinet at a low level, ventilation holes are usually provided on the cabinet. , and a fan is installed to make the air flow in the cabinet smooth and achieve the purpose of cooling down. However, this cooling method makes the cabinet cavity connected with the outside world, so that a large number of dust particles from the outside enter the cabinet and accumulate for a long time. A large amount of dust The accumulation on the surface of electrical components greatly reduces the heat dissipation effect of electrical components, and the heat accumulates inside the electrical components, thereby burning out electrical components and even causing fires.

Detailed ways

The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

Please refer to Figures 1 to 4, a new type of air heat exchange cooling substation, including a cabinet body 1, the inner cavity of the cabinet body 1 is provided with three vertical first partitions 3, and the side ends of the three first partitions 3 They are sequentially connected to form a "冂" shape (as shown in Figure 4), and together with the front side wall and the upper and lower walls of the cabinet 1 form the electrical component chamber 4; the three first partitions 3 and the other inner walls of the cabinet 1 form a cooling Cavity 5, the section of the cooling cavity 5 is a U-shaped structure, the electrical component cavity 4 is evenly provided with a number of second partitions 6 from top to bottom, and the second partition 6 separates the electrical component cavity 4 into a number of installation cavities, the first partition 3 and the second partition 6 are made of materials with good thermal conductivity, the top wall of the cooling chamber 5 is evenly provided with a number of air outlets 7, each of the air outlets 7 Fans 14 are provided at the top, and a number of air inlets 8 are provided at the bottom of the side wall of the cabinet body 1.
