Description

A new type of prefabricated substation

technical field

The utility model relates to power transmission and transformation equipment, that is, a novel prefabricated substation.

Background technique

The prefabricated substations widely used in our country, commonly known as box-type substations, have two types: European-style and American-style, each with its own characteristics and disadvantages. Separated, bulky, poor heat dissipation. The American-style box-type substation has better heat dissipation conditions in spring and autumn because the heat sink directly dissipates heat to the outside, but in the southern summer, the sun is directly shining, and the temperature inside the box is very high; The generated arc is easy to carbonize the transformer oil, causing the temperature of the oil surface to rise, which is easy to oxidize, and affects the insulation performance of the transformer oil.

Contents of the invention

In order to overcome the disadvantages of large volume and poor heat dissipation of the European-style box-type transformer and poor heat dissipation and unsafety of the American-style box-type box-type transformer, the utility model proposes a new type of transformer that combines the advantages of the European-style box-type transformer and the American-style box-type transformer, has good heat dissipation, is safer, and is small in size. design.

This new prefabricated substation consists of a box and a high-voltage room, a low-voltage room and a transformer room in the box. A high-voltage switch is installed in the high-voltage room, a low-voltage switch is installed in the low-voltage room, and a transformer is installed in the transformer room. It is characterized in that the box The body is a cuboid, the low-voltage room is on one side of the long side, and the high-voltage room and transformer room are on the other side of the long side. The above three rooms are all cuboid, separated by partitions. The three chambers are arranged in a font, and there are connecting lines between the three chambers. There are heat dissipation windows on the box plates at both ends of the box body of the high-voltage room and the low-voltage room. There are also heat dissipation windows on the box plate and door of the box body of the transformer room. 1 to 2 doors are respectively arranged on the box body board facing outwards of the transformer room.

In the low-voltage room, the upper part is the metering room, and the lower part is the capacitor room and the outlet room.

The transformer is a general oil-immersed transformer or a dry-type transformer.

The high voltage switch is a sulfur hexafluoride load switch.

The low-voltage room can be equipped with a capacitance compensation device.

The advantages of the utility model are: 1. Small size, light weight, good ventilation performance, which can eliminate the danger of insulation accidents caused by condensation; 2. Dust-proof, moisture-proof, small animal-proof, safe and reliable, and easy to maintain; 3. High voltage The switch adopts sulfur hexafluoride load switch, which can realize ring network, double-circuit or terminal power supply; 4. The low-voltage side is equipped with a capacitor compensation device, which can realize high-voltage power supply high-voltage metering or high-voltage power supply low-voltage metering, and multi-circuit outlets can also be used.
