Embodiment Construction

[0052] like figure 1 and figure 2 As shown in the figure, a GIS equipment extension module without power interruption provided by the present invention includes a left double isolation fracture three-station isolation grounding sub-module 1, a right double isolation fracture three-station isolation grounding sub-module 2, and a middle grounding sub-module 3, and The intermediate sub-module extends downward and is arranged in a transition air chamber. Sub-modules are connected to each other through their respective interfaces.

[0053] The left double isolation fracture three-station isolation grounding sub-module 1 and the right double isolation fracture three-station isolation grounding sub-module 2 have the same structure, with two isolation fractures and one grounding fracture inside, and two isolation fractures and one grounding fracture. Mechanical interlocking can be achieved between them, and synchronous opening or closing can be realized.

Abstract

The invention relates to the technical field of power transmission, in particular to an uninterruptible extension module of GIS equipment, which comprises a left double-isolation fracture three-station isolation grounding sub-module, a middle grounding sub-module and a right double-isolation fracture three-station isolation grounding sub-module, the middle grounding sub-module extends downwards to be provided with a transition shell; two mutually vertical isolation fractures and a grounding fracture are integrated in the double-isolation fracture three-station isolation grounding sub-module; a first air chamber is formed in the left double-isolation fracture three-station isolation grounding sub-module, a second air chamber is formed in the right double-isolation fracture three-station isolation grounding sub-module, a third air chamber is formed in the middle grounding sub-module, and a transition air chamber serving as an extension port is formed in the transition shell. According to the invention, four obvious isolation fractures can be formed in the extension device without power failure, grounding devices of the three sub-modules are all connected, dual-linkage control is formed between the live bus and the reserved interval, and it is ensured that the GIS bus is free of power failure and operates safely and reliably in the whole extension process.

Description

technical field [0001] The invention relates to the technical field of power transmission, and relates to an uninterrupted expansion module of GIS equipment and an expansion method thereof. Background technique [0002] GIS equipment (Gas Insulated Switchgear, gas-insulated metal-enclosed switchgear), as a key equipment for power transmission and transformation, has been widely used in power systems due to its advantages of compact structure, safe and reliable operation, short maintenance time, and no influence from the external environment. As an example of electrical equipment, the task of the isolating switch in GIS equipment is to withstand a certain rated voltage for a long time and provide a reliable grounding when required. [0003] With the wide application of GIS, more and more GIS projects need to be constructed in stages due to a series of factors such as equipment cost, project investment, and power system planning. In some large-scale GIS projects, in order to ...
