Basic Composition and Development Trend of Transformer Substation

Transformer substation is power appliance in electric energy system that switches voltage, accept and distribute electric power and control electric flowing path also as adjusting voltage. It connects power grid of voltage with different levels by transformer. Here, the gear using the function of switching energy is transformer. Except for this, additionally, it includes switching device opening and closing circuit, generatrix assembling currents, mutual inductor for measuring and controlling, meter, relay protection device, lightning protection device and dispatching communicator. Some, like Combined Substation even contains reactive-load compensation equipment.

Transformer

Transformer will be the primary device in transformer substation. Provided by transformer producers, you will find two-circuit transformer, three-winding transformer and auto-transformer, also transformer specially designed by transformer manufacturer, whose higher and low stress share a winding inside every phase by extracting one head from higher stress winding to act as the outlet of low stress winding. The voltage strength is direct proportion to winding quantity whereas the current is in inverse proportion to it.

Switching device

Switching device consists of breaker, disconnector, Load Breaker Switch and high voltage fuse which are all devices for connecting or breaking the circuit. Here, breaker is used to connect and break circuit in the situation of energy system normal operation and in the situation of breakdown automatically break the circuit from breakage device below the protection of relay protection device. Also, it has the function of automatically reclosing lock. For other switching devices, some like ring main unit switchgear are mostly applicable for 36kv switchgear for the moderate voltage.

Much more intelligent

Intelligent transformer substation( Intelligent Switchgear) has traits of informatization, automatization and interaction. Intelligence mainly embodies in two elements, intelligent device and intelligently sophisticated application. Intelligent device realizes organic separation of one-time device and intelligent element. To become exact, intelligent device assists one-time device to finish transmitting and distributing electric energy at meanwhile of measuring, controlling, sustaining and metering.

More secure and green

Transformer substation technical advance ensures efficiency and precision in data transmitting which promotes power provide stability and guarantees energy grid much more stable operation. With further adaptation, modularization and standardization in intelligence technology, the info collecting, transmitting and processing turn out to be much more regular, successfully supporting ??one-whole regulation and one-whole operation?ˉ. Detection measures like Integration video linkage and state analysis well make sure pr¨|cised sequential control and unattended operation. Also, it achieves power saving and emission reduction by advertising device resource utility ratio and steady power supply(Power Distribution Box Manufacturer).
