Description
Technical field
The utility model is related to a kind of transformer pressure-reducing formula auto-reactive compensation equipment applied to power system.
Background technology
Traditional transformer station's high-tension line compensation equipment, mostly high-voltage parallel compensation equipment, compensation capacitor is in order to reach
The operational voltage level of itself, takes many cascaded structures to carry out partial pressure mostly, while to ensure apparatus insulated level, Suo Youpei
Complete equipment insulator is using the design that disclosure satisfy that line voltage distribution grade, therefore occupation area of equipment is big, and device height is up to
10m or so.Realized compensation control aspect is all the quantity that is put into by capacitor, this certainly will bring two problems：One
It is no matter how capacitor to be grouped to the change for being impossible to complete adaptive system inductive reactive power, can only be in a certain larger scope
Inside it is adjusted, it is impossible to realize fine tuning；Two be that capacitor switching produces overvoltage, and frequent operation will have a strong impact on capacitor
Service life, therefore, it is impossible to real-time, appropriate capacitance compensation is realized, can only be idle to system or a certain region in a certain period
Inside optimize control.In addition, the operating problem of shoving of capacitor, general to be limited using current-limiting reactor, so must
The reactive loss that a part of capacitor is used for direct compensation current-limiting reactor is so sacrificed, increases the investment of capacitor, and is connected
Reactor improves the working voltage of capacitor again, has a strong impact on the life-span of capacitor, and these problems make traditional idle control
Device can not be played a role, and voltage power-less management cannot be improved effectively.
The content of the invention
The purpose of this utility model is to provide a kind of transformer pressure-reducing formula auto-reactive compensation equipment, solves high-tension line and mends
Repay that capacitor series connection number of units is more, floor space is big, device height is high, maintenance difficult, it is impossible to continuously adjust, big to system shock,
And the problem of complex management.
Technical solution of the present utility model is：A kind of transformer pressure-reducing formula auto-reactive compensation equipment, including it is idle
Control device and the capacitor bank for compensation are compensated, it is characterized in that：In high-pressure system by the first disconnecting switch and
First breaker simultaneously connects compensator transformer, and installed on the compensator transformer has a load partial pressure switch with multi-gear adjustment, described
Compensator transformer secondary is connected by the second disconnecting switch and the second breaker with the capacitor bank, first breaker and
The executing agency of second breaker is connected with the reactive compensation controlling device.
Reactive compensation controlling device is according to the system three-phase current and voltage by current transformer and voltage transformer collection
Sampling, is calculated by CPU, when needing that primary equipment is adjusted, the executing agency said the word to corresponding interval unit, life
Order sends the rear device implementing result that monitoring is acted automatically.
The beneficial effects of the utility model are：It is compensated transformer pressure-reducing to designed voltage to change high-voltage capacitor switching
Once fixed access after grade, the purpose of change compensation capacity is reached by changing capacitor end voltage, capacitor is solved
Overvoltage in switching and the technical problem such as shove, change and delayed are adjusted to real-time continuous regulation, service life of equipment length, loss
It is low, the low person of expense of equipment final-period management, it is ensured that equipment safety operation.
