Fundamental Composition and Improvement Trend of Transformer Substation

Transformer substation is energy appliance in electric power system that switches voltage, accept and distribute electric energy and manage electric flowing direction also as adjusting voltage. It connects energy grid of voltage with different levels by transformer. Here, the gear with the function of switching energy is transformer. Except for this, additionally, it consists of 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 gear.

Transformer

Transformer will be the main device in transformer substation. Supplied by transformer producers, you will find two-circuit transformer, three-winding transformer and auto-transformer, also transformer specially developed by transformer manufacturer, whose high and low stress share a winding within each phase by extracting one head from high pressure winding to act because the outlet of low stress winding. The voltage strength is direct proportion to winding quantity whereas the present is in inverse proportion to it.

Switching device

Switching device consists of breaker, disconnector, Load Breaker Switch and higher voltage fuse which are all devices for connecting or breaking the circuit. Here, breaker is utilized to connect and break circuit in the condition of energy system regular operation and within 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.

More intelligent

Intelligent transformer substation( Intelligent Switchgear) has traits of informatization, automatization and interaction. Intelligence mainly embodies in two aspects, intelligent device and intelligently advanced 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 power at meanwhile of measuring, controlling, sustaining and metering.

More safe and green

Transformer substation technical advance guarantees efficiency and precision in information transmitting which promotes energy provide stability and guarantees energy grid more stable operation. With further adaptation, modularization and standardization in intelligence technology, the information collecting, transmitting and processing become more standard, successfully supporting ??one-whole regulation and one-whole operation?ˉ. Detection measures like Integration video linkage and state evaluation well ensure pr¨|cised sequential manage and unattended operation. Also, it achieves power saving and emission reduction by promoting device resource utility ratio and steady energy provide(Power Distribution Box Manufacturer).
