Description
Technical field
The utility model relates to a kind of intelligent transformer with phase selection function circuit breaker.
Background technology
The combined transformer that present 10kV distribution line uses is all that on-load switch+fuse provides protection mostly, has been difficult to adapt to new period national economy and social development to the requirement of electric power system high reliability.
Because use fuse to protect, due to inherent shortcoming and the quality problems of its equipment self, cause its protection cannot coordinate with higher level transformer station.In addition after fuse protection act, promptly and accurately cannot to locate and reporting fault, cause follow-up malfunction elimination, restore electricity and need spend a large amount of time, man power and material in time, extend interruption duration.
In reality, the dependence of social economy to electric power is growing, proposes stricter requirement to the reliability of power supply.The impact of power outage on whole national economy and life is very large, and direct and consequential damage is inestimable.
In addition, transformer, when particularly high-power transformer puts into operation, its open-circuit excitation is shoved may very large (maximum reach more than tens times of transformer rated current), power transmission often occurs and to close a floodgate unsuccessful situation.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of intelligent transformer with phase selection function circuit breaker, and this device can realize running status Autonomous test, self-shield.
For solving the problem, the utility model adopts following technical scheme:
A kind of intelligent transformer with phase selection function circuit breaker, comprise oil tank of transformer, the inside of described oil tank of transformer is provided with transformer, the top of described oil tank of transformer is provided with the high-tension cable sleeve pipe and low-voltage cable sleeve pipe that connect described transformer, described transformer oil box top is also provided with a circuit breaker, described circuit breaker is connected to described transformer and between described high-tension cable sleeve pipe and low-voltage cable sleeve pipe, described transformer oil box top is also provided with the off circuit tap changer that connects described circuit breaker, described circuit breaker comprises permanent magnet mechanism, insulated tension pole and vacuum interrupter, described permanent magnet mechanism connects described vacuum interrupter by insulated tension pole, described off circuit tap changer connects described permanent magnet mechanism.
As preferred technical scheme, the top of described oil tank of transformer is provided with the oil inlet pipe of supplementary fluid.
As preferred technical scheme, described high-tension cable sleeve pipe is connected with high-tension current inductor.
As preferred technical scheme, described low-voltage cable sleeve pipe is connected with low-voltage current mutual inductor.
The beneficial effects of the utility model are: this utility model can realize the low combined floodgate power transmission of shoving of no-load transformer, greatly reduces the impact to electrical network.Circuit breaker three-phase is driven by three permanent magnet mechanisms alone respectively, under intelligent permanent magnet driver drives, according to the voltage synchronous signal that voltage transformer detects, drives circuit breaker three-phase to close a floodgate at corresponding switching-on phase angle respectively.
This utility model can realize state Autonomous test, the self-shield of transformer equipment.The various parameter of care testing device at ordinary times, record, process, realize equipment self-diagnosis accurately, realizes fault pre-alarming and service life of equipment assessment, realize the isolation on the spot to equipment short trouble.This utility model overcomes the weak point of existing oil-immersed type transformer, realizes long-haul telemetry remote signalling, greatly simplifies transformer equipment O&M cost, and improve the operational reliability of equipment, face the future intelligent grid.
