Method for defining aviation plug pins of 220kV GIS control cabinet

Abstract

The invention relates to a method for defining aviation plug pins of a 220kV GIS control cabinet. The method comprises the steps that aviation plugs are used for replacing an original terminal strip in the GIS control cabinet of a transformer substation and a prefabricated cable is used for replacing an original control cable; the aviation plugs used by spaced GIS control cabinet portions are distinguished according to functions; the number of cores of the aviation plugs and the number of the aviation plugs are set and the aviation plug pins are defined. According to the GIS control cabinet, simplification and optimized integration are conducted on a traditional cable secondary loop through the aviation plugs, so that wire connection of the loop is clear and reasonable and the pin definition is standardized and unified. Configuration and definition of the aviation plug pins of the 220kV GIS control cabinet are modularized, generalized and standardized, the advantages of the quality and the cost of the aviation plugs of the prefabricated cable in a factory are fully used, the construction cost and installation cost of the transformer substation are greatly reduced, the construction period is shortened, the maintenance workload is reduced, the reliability of a system is improved, and the purpose that once the plug is plugged in, the secondary device of the transformer substation can be used is achieved.

Description

technical field [0001] The invention belongs to the field of electrical technology, and in particular relates to a method for defining pins of aviation plugs of a 220kV GIS control cabinet. Background technique [0002] At present, the connection scheme between the substation GIS central control cabinet and the primary equipment is generally: terminal blocks are set on both sides of the central control cabinet, and the lead-out cables of the primary mechanism are connected to the central control cabinet terminal blocks. With the development of smart substations, there are higher and higher requirements for equipment structure layout and function integration. In addition to conventional equipment such as the control handle of the mechanism body, the operating outlet pressure plate, and analog wiring, the GIS control cabinet also needs to install " In-situ arrangement of merging units, smart terminals and other intelligent components, and "in-place release" of secondary equipm...

Problems solved by technology

After engineering application exploration, a lot of valuable experience has been accumulated in the use of aviation connectors. However, the differences between the products of various manufacturers make the selection specifications of aviation plugs no uniform standard, and the pin definitions of aviation connectors at different intervals There is no uniform specification, so that the aviation plugs used by various manufacturers are various, and even the aviation plugs used by the same manufacturer in different substation projects are also different, which is not conducive to the use of aviation plugs in substations to achieve "plug and play" at the same time.
