Abstract
The invention relates to a smart transformer. Smart fuses are respectively connected into an input coil circuit and an output coil circuit of the transformer in series and are packaged to form the smart transformer. A circuit input end of the transformer is parallelly connected with a power source indication circuit consisting of a resistor and a diode which are connected in series.
Description
Technical field
The present invention relates to a kind of transformer, relate in particular to a kind of intelligent transformer.
Background technology
At present, the overcurrent of known railway control transformer, excess temperature and thunder and lightning interference protection are accomplished by the protection equipment of peripheral hardware.Like: overcurrent with fuse, thunder and lightning interference protection with lightning protection unit device etc.These devices especially overcurrent protection are used fuse, will fuse in case circuit is short-circuited, and their shortcoming is only can protect once, and having fused just needs to change.In addition, add up because these protection equipment are all outer, therefore, circuit complex connection, on-the-spot inconvenient installation.
Summary of the invention
The object of the invention is exactly in order to solve the deficiency of above-mentioned prior art, a kind of intelligent transformer to be provided, and it not only has overcurrent, excess temperature and thunder and lightning interference protection, and can eliminate the back in fault and restore automatically and connect circuit.
Be to realize above-mentioned purpose, the technical scheme that the present invention takes is: a kind of intelligent transformer is characterized in that it is serially connected with Intelligent fuse respectively to encapsulate in transformer input, the output winding circuit to form.Also be parallel with the power indicating circuit that forms by resistance and diode serial connection at the input of above-mentioned transformer circuit.
Beneficial effect provided by the invention, simple in structure, reasonable in design, on-the-spot easy for installation.At circuit power supply system just often, intelligent fuse does not shield, the transformer operate as normal; After fault is eliminated, restore automatically, connect circuit.
