Temperature monitoring in current high voltage electric equipment generally adopts signal wire to transmit the temperature signal detected, and need to connect up, not only cost is high, and complex process.
Summary of the invention
It is low that the purpose of this utility model is to provide a kind of cost, can realize the wireless high-voltage temperature sensor of Wireless transceiver temperature signal.
For achieving the above object, the technical solution of the utility model is: wireless high-voltage temperature sensor, it is arranged in high voltage electric equipment, it comprises the collar, temperature probe and circuit board, the described collar comprises annulus and pedestal, annulus is fixed on pedestal, and circuit board is arranged in pedestal, and circuit board is provided with wireless signal transmitter; Temperature probe one end is electrically connected with circuit board, and the other end wears annulus; When temperature is detected, annulus is set in by outside thermometric object, temperature probe other end induction testee temperature.
The utility model adopts above structure, detected by the temperature of thermometric object (such as high-voltage busbar) by temperature probe, again the temperature signal detected is sent to circuit board, circuit board processes the temperature signal received, and the temperature signal after process is sent to the controller in high voltage electric equipment by wireless signal transmitter.Because the utility model adopts wireless signal transmitter to carry out transmission temperature signal, without the need to connecting up, cost-saving, meanwhile, temperature signal transmits safe and reliable, little by such environmental effects.
The inner ring of described annulus is provided with Self tightening device, and by this Self tightening device, annulus can be set in securely by outside thermometric object.
Described Self tightening device comprises the support column be fixed on annulus inner ring surface, and the head of support column is provided with elastic layer, when annulus is set in outer by thermometric object, the elastic layer of support column head with offseted by thermometric object.By arranging elastic layer at support column head, make annulus can with being coordinated by thermometric object of different model.
Be sealed with inductive power supply CT in described annulus, circuit board is powered by the CT that powers, thus can effectively solve other power supply modes such as battery need have a power failure change battery and hot environment under to work unsafe shortcoming.
Described temperature probe is platinum resistor temperature measuring probe, and platinum resistor temperature measuring probe thermometric is precise and stable, by force high temperature resistant.
Described annulus and pedestal one-body molded by epoxide resin material, thus make the collar easy to process.
Wireless high-voltage arrangement of temperature sensor of the present utility model is simple, convenient for production.Simultaneously by adopting wireless signal transmitter to carry out transmitting the temperature signal detected in the inner, thus without the need to connecting up, eliminating processing step, reducing production cost; In addition, wireless signal transmitter is adopted to transmit temperature signal safe and reliable, little by such environmental effects.
