1、Brief Introduction on Transformer Substation
Transformer substation is one of the power supply facilities, a location what's utilized for voltage change. the voltage should be risen in order to transmit the energy of electric energy to a distant location, and after that decrease the voltage based on the need of customs when close to the user , this function is completed by converting station , whose primary substation equipment is switchgear and transformer. The ring primary unit switchgear is equipped having a vacuum load switch, spring operating mechanisms that may manual operation, but also electric operation.
According to the various size, small substation also known as for substation, energy distribution space and so on. Substation voltages transforms and distribute electricity.
two. The basic Type of Transformer
The basic kind of transformer consists of two groups of coils and be together with each other by inductance. When an alternating current (with a recognized frequency) have a tendency to be 1 of the coils, and the other coil will induce exactly the same frequency voltage, and induced voltage depends on the two coil coupling and magnetic exchange chain level.
American kind substation enclosure series is used in 10kv loop net energy provide, double- energy supply or terminal power supply systems as HV power distribution measuring, compensation control and protection equipments, What is completely sealed and insulated. The HV load switch, HV fuse can be placed in transformer oil. These elements can be separated from transformer body or enclosed within one compartment with transformer body. The material of this is qualified cold-rolled steel plates that have high bending, compact resistance and ensile strength. The surface has higher anti-corrosion home with static powder coating processing.
four. Combined SubstationCombined substation is a kind of equipment consists of switch, transformers, low voltage apparatus using the features as followings:
1) Series, modular design.
2) Substation has the benefits of compact structure, small volume, little occupying region, short building period, less investment.
three) Superb temperature, humidity manage and atmosphere monitoring system, dependable gear operation atmosphere.
4) Convenient in and out cable way.
five) Transformer manufactures will offer shell with environmentally friendly materials and high quality heat insulation sandwich board for users to select.
Digital substation is essential for the technologies of automatic substation, which has the milestone significance. and can have a far-reaching influence on the numerous aspects of the substation automatic method. Three primary function of digital substation is "a intelligent gear, secondary gear network, in line using the IEC61850 standard”, that is to say, all of the info will probably be digital, varies of devices could share a unified information platform. Substantial improvement will be made in method reliability, economy and maintence.(Europe Type Substation)
