Prefabricated cabin for secondary equipment of 110-kV transformer substation

Abstract

The invention discloses a prefabricated cabin for secondary equipment of a 110-kV transformer substation 110kV. The prefabricated cabin divides the secondary equipment into a plurality of functional modules according to functions, wherein the function modules are composed of a main console module, a protection measurement and control module, a switch module, a total station public module, a safety automation module, a metering monitoring module, a power supply module and a communication equipment module; and the cabin body of the prefabricated cabin for the secondary equipment is transversely divided into a plurality of spaces, and the functional modules are sequentially placed in the divided spaces of the prefabricated cabin. According to the prefabricated cabin for the secondary equipment of the 110-kV transformer substation, the cabin body is divided by taking intervals as units, and the secondary equipment is modularly divided according to functions, so standardized and simplified arrangement is realized, breakpoints and switching of optical cables among the secondary equipment are reduced to the greatest extent, wiring work is simplified, engineering efficiency is improved, and a station construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of substation secondary equipment, in particular to a 110kV secondary equipment prefabricated cabin. Background technique [0002] In China, substations usually take a long time from planning to commissioning. There are three main reasons: First, the construction period is long. The construction of substations involves planning and site selection, survey and design, project construction, material procurement, installation and construction, commissioning and commissioning acceptance, etc. For the full-cycle work content, taking a 110kV conventional substation as an example, its construction period often takes 20 to 24 months; second, with the continuous improvement of the intelligence level of substations and the refinement of electrical equipment, the planning and design, on-site construction, The requirements for commissioning personnel have also increased, and it is difficult to compress the construction p...

Problems solved by technology

[0004] However, due to the complexity of the optical cables between the secondary screen cabinets and the cables between the secondary equipment and the primary equipment, it still takes a lot of time for wiring at the construction site
