Embodiment Construction

[0034] Normal working condition

[0035] Figure 2A Show reference figure 1 The main element of the described prior art substation, that is, the high-voltage power line 1 reaches the input and output point 6, which is arranged in the vicinity of the two lateral bridge portals 15 to which the line is connected by an insulator 26. The device on the ground between these bridge portals is a GIS, which includes one or more sets of main busbars 14 necessary for the operation of the substation, and each of these busbars is arranged in the metal shell 13. The figure also shows a movable first overhead connecting conductor 2 which is connected to a connecting arm 16 extending through the structure of the building so as to send power into the inside of the GIS 10. Therefore the GIS 10 is within the building 10 represented by its top 11.

[0036] The novelty of the present invention is that the emergency busbars 24 are not arranged on the side of the building away from the GIS10, but each bu...

Abstract

A transformer station can manage a great amount of high-voltage power lines (1) arriving at anyone side of the transformer station without occupying wide areas or big volume. A gas-insulated transformer station (10) comprises various compartments (12) for treating the electric power and a bus (14). The power can be normally transmitted to the compartments by an overhead conductor (2) and a closed wall outlet bushing (16). An emergency bus (24) is arranged on the gas-insulated transformer station (10), preferably on a roof (11) of a building, and the emergency bus is connected to various high-voltage power lines (1) by a wire perpendicular to the bushing (25). Therefore, any available compartment can be used as the emergency compartment, and a plurality of compartments of the gas-insulated transformer station (10) can be short-circuit.

Description

Technical field [0001] The present invention relates to a substation for power distribution and processing high-voltage electricity. The substation is most often installed outdoors and is suitable for receiving power from a power generating device that generates power and sending the power to users and consumers of power. [0002] More specifically, the present invention relates to the technology of so-called metal-enclosed gas insulated substations. Background technique [0003] First, it should be explained that the concept of high-voltage transmission and distribution, especially in the case of high-voltage substations, uses two kinds of conductor insulation technology. The first technology is air insulation technology, and the second technology is metal enclosed insulation technology. [0004] Air insulation technology is used for "high voltage" types of power lines, such as the transmission lines that are most common in rural areas and are erected by electric towers up to sever...
