Energy-saving box type outdoor substation

Abstract

The invention belongs to the power transmission and transformation equipment field and relates to an energy-saving box type outdoor substation. The substation comprises a top cover and a box body; the box body is divided into a high-voltage chamber, a transformer chamber and a low-voltage chamber. The energy-saving box type outdoor substation further comprise an intelligent controller; the intelligent controller is connected with a low-voltage chamber power transmission line through a power source input cable; the high-voltage chamber is provided with a high-voltage entering cabinet, a high-voltage metering cabinet, a high-voltage ring main unit and a high-voltage outgoing cabinet; the low-voltage chamber is provided with a low-voltage entering cabinet, a high-voltage reactive power automatic compensation capacitor cabinet and a low-voltage outgoing cabinet; and a transformer arranged in the transformer chamber is an on-load automatic capacitance adjustment power distribution transformer. The energy-saving box type outdoor substation is safe, reliable, energy-saving and efficient. With the energy-saving box type outdoor substation adopted, a power factor as well as the power supply efficiency and voltage quality of a system can be improved, and line loss can be decreased, and distribution line cost can be decreased, and electric energy can be saved, and the occupancy of a power grid and the no-load reactive loss and active loss of the transformer can be decreased, and capacity increasing cost and operation cost can be saved, and saving energy and consumption reduction can be realized, and great economic benefits and social benefits can be brought about.

Description

technical field [0001] The invention belongs to the field of power transmission and transformation equipment, and in particular relates to an energy-saving box-type outdoor substation. Background technique [0002] Outdoor box-type substation is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device. According to the predetermined wiring scheme, the functions of high-voltage power receiving, transformer step-down, and low-voltage power distribution are organically combined, and it is installed in a closed, movable The fully enclosed operation of the box is especially suitable for urban network construction and transformation. It is a brand-new substation rising after the civil substation. In actual use, there are the following problems. Since the transformer capacity of the substation is generally selected according to the maximum load of the vision, the no-load loss is relatively large, especially the unbalanced power consumpt...

AI Technical Summary

Problems solved by technology

As a result, the grid occupancy rate, no-load loss and load loss are high, which reduces the power factor of the grid and increases the network loss, thereby greatly increasing the capacity expansion fee and operation fee, resulting in high energy consumption

In addition, there is currently no professional equipment that can monitor the working status of outdoor box-type substations and provide early warnings for abnormal working status. Workers are required to go to patrol and inspect, resulting in a large amount of manpower and material resources, and the cost of substation maintenance is relatively high.

In addition, its use is huge and widely distributed, resulting in an increase in the daily maintenance workload. Especially when a fault occurs, the location of the fault point and fault information cannot be accurately grasped at the first time, and it also brings greater costs to power overhaul and maintenance. Difficult, reducing troubleshooting rates

In addition, the existing outdoor box-type substation mainly uses the installed fan to blow cooling air and mix with the hot air in the box to dissipate heat. The heat dissipation is slow and intelligent control cannot be realized, which wastes a lot of electric energy and is not energy-saving.
