Description
Technical field
The invention belongs to technical field of electrical measurement, be specifically related to wireless remote control error zeroing instrument transformer.
Background technology
The inductance that instrument transformer has due to itself and resistance, therefore, phase error and ratio error is certainly led in power transformation process, prior art is generally by shunt capacitance on the secondary coil of instrument transformer and/or series resistance thus by the error transfer factor of instrument transformer in required error range, but the problem brought is, each instrument transformer all needs to debug separately, and configuration electric capacity or resistance, cannot accomplish scale production separately; Further, when carrying out annual test according to vertification regulation, overproof instrument transformer is also needed to tear machine adjustment open, particularly for the instrument transformer of cast encapsulation, cannot shell adjustment be opened, only have and scrap process, cause waste.
Summary of the invention
The object of the invention is to solve prior art Problems existing, provide and get final product wireless alignment error and the wireless remote control error zeroing instrument transformer that can repeat adjustment without the need to opening shell.
The present invention solves the problems of the technologies described above the technical scheme taked to be:
Wireless remote control error zeroing instrument transformer, the adjustable resistor assembly comprising instrument transformer body, be connected in parallel on the adjustable condenser assembly in secondary winding and be connected in secondary winding; Be characterized in: described adjustable condenser assembly comprises capacitor body and capacitor wireless remote control mechanism, described adjustable resistor assembly comprises resistor body and resistor wireless remote control mechanism; Described capacitor wireless remote control mechanism and resistor wireless remote control mechanism to be gone forward side by side the news that work by the control that ZigBee wireless network accepts wireless controller.
The present invention compared with prior art, has following beneficial effect:
The present invention adopts parallel connection in the inner secondary winding of instrument transformer to connect remote controlled adjustable condenser assembly and series connection remote controlled adjustable resistor assembly in secondary winding, thus make instrument transformer can unify configuration error transfer factor element in the fabrication process, large-scale production can be carried out, and realize automatically carrying out error transfer factor calibrating on streamline, and can be zero by error transfer factor during nominal conditions between instrument transformer and standard mutual inductor, during annual test, only need operate wireless controller can carry out the adjustment of error for overproof instrument transformer without the need to opening shell, for the instrument transformer of moulding by casting, its error is overproof also need not scrap, production efficiency greatly improves, and avoid waste.
