Fundamental Composition and Development Trend of Transformer Substation

Transformer substation is energy appliance in electric energy system that switches voltage, accept and distribute electric energy and control electric flowing path also as adjusting voltage. It connects power grid of voltage with different levels by transformer. Right here, the gear with the function of switching power 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 consists of reactive-load compensation equipment.

Transformer

Transformer will be the main device in transformer substation. Supplied by transformer manufacturers, there are two-circuit transformer, three-winding transformer and auto-transformer, also transformer specially designed by transformer manufacturer, whose high and low pressure share a winding within every phase by extracting 1 head from high stress winding to act as the outlet of low stress winding. The voltage strength is direct proportion to winding number whereas the present 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 utilized to connect and break circuit within the situation of power method normal operation and in the condition of breakdown automatically break the circuit from breakage device below the protection of relay protection device. As well, it has the function of automatically reclosing lock. For other switching devices, some like ring primary 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 component. To be exact, intelligent device assists one-time device to finish transmitting and distributing electric power at meanwhile of measuring, controlling, maintaining and metering.

Much more secure and green

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