Abstract
The design was entitled “Liaoning University of Technology electrical substation part of the design.” First choice for the main transformer; main electric wiring of choice in accordance with the characteristics of the main cable, select the various levels of voltage wiring, integrated, choose the best connection mode; After a short-circuit current calculations, according to short-circuit current calculation of electrical equipment choice of generators and transformers for protection of the design; after the Lightning Protection in conjunction with the actual drawing design drawings, including floor plans, profiles, the main electric cable Plans, protection plans and mine access maps.
Liaoning University of Technology electrical substation main connection of high-pressure side of the single-bus wiring, low-pressure side of the single-section of the bus main electric connection forms; calculated according to the load on the main transformer right to choose; calculated short-circuit some of the harm, including short-circuit, Short circuit, and the choice of specific numerical calculation; Electrical equipment options include the classification of electrical equipment, high-voltage circuit breakers, switches isolation, current transformers and voltage transformer and the choice of checking; relay designed mainly to relay that the basic requirements and principles of the transformer and a current speed off Over-current protection and the protection of the design calculated that its distribution of the types of devices, applications and design steps, using a set distribution equipment; lightning protection lightning rod used to protect anti-Zhiji Lei.
The design of the integrated use of electrical knowledge on the part of the 10 KV substations for the design of a more detailed description, including graphics and text that described, language easily understood.
