Product Manufacturing Process
Transformer substation plays the role of voltage conversion equipment is transformer, in addition, substation equipment also open and close circuit switchgear, current collection bus, measurement and control transformers, meters, relay protection devices and lightning protection devices, dispatching communication devices, and some substations have reactive power compensation equipment. The main equipment and connection mode of substation vary according to its different functions.
Transformer is the main equipment of substation, which is divided into double-winding transformer, three-winding transformer and self-destructive transformer, that is, high and low voltage each phase share a winding, and a head is drawn from the middle of the high voltage winding as the outlet of the low voltage winding transformer. The voltage is proportional to the number of turns and the current is inversely proportional to the number of turns.
Fields of application
In addition to providing convenience for People’s Daily electricity needs in the city, substations are also widely used in wind farms, photovoltaic power stations, hydropower stations, nuclear power plants, hub substations, important converter stations, backbone power grids, important transmission channels and other energy infrastructure scenarios
The daily management of the use of substation equipment is responsible for the implementation of the principle of “who uses, who manages”. Equipment personnel should be employed, and the equipment personnel should have basic knowledge of substation equipment and certain experience in equipment management. The use of substation equipment should be equipped with sufficient staff (operators, command personnel and maintenance personnel) in accordance with regulations. Operators must be licensed to work in accordance with regulations. The staff used by the substation equipment should be competent for the work performed and familiar with the performance characteristics and maintenance requirements of the equipment used.
