The described temperature sensor of technical solution of the present utility model is a kind of infrared temperature sensor, its temperature-measurement principle is: testee be heated the back to around emittance, what relevant with temperature, radiation wavelength, the material of object (general bright laws) of emittance are if the integrated radiant emittance of consideration object is by this fence of making a mistake-Boltzmann law E=σ ε T
4(in the formula: σ is an absolute temperature for this fence-Boltzmann constant of making a mistake, T, and ε is an emissivity) if measure testee institute radiation emitted power, just can determine the testee temperature.
The described temperature sensor of technical solution of the present utility model is a kind of non-contact type infrared temperature sensor, this is that heating radiator does not contact on a kind of and the high-pressure thyristor, but the radiation heat that utilizes spreader surface to send is measured temperature, be referred to as the non-contact type infrared temperature sensor, its thermometric process is, the heat energy that produces during high-pressure thyristor work is delivered on the heating radiator by certain coefficient linear relationship by tube core, heating radiator Yin Wendu raises and produces heat radiation, the infrared ray that infrared source produces just in time supplies the infrared temperature sensor thermometric used, temperature sensor converts the infrared ray strong and weak signals that collects the output of to corresponding electric signal, is delivered to universal intelligent temperature digital display instrument by cable and shows and control.During thermometric, infrared temperature sensor does not contact with testee (high-pressure thyristor heating radiator), therefore this temperature measuring equipment can not damage the temperature field of testee (high-pressure thyristor heating radiator), also need not be in the temperature field, under the condition that guarantees the electrical safety distance, can exempt from high-tension destruction.
Heating radiator on the high-pressure thyristor described in the utility model technical solution, it is to be connected to form by thyristor core and heating radiator, the heat energy that produces during thyristor work is delivered on the heating radiator by thyristor core, and the radiator heat radiation source on the heating radiator is for the usefulness of infrared temperature sensor temperature-sensitive.
The utility model beneficial effect is: because the temperature sensor described in the technical solution adopts the non-contact type infrared temperature sensor, temperature measuring equipment has untouchable, guaranteed the safe distance between high-pressure thyristor trigger low tension control components and parts and the high-tension electricity components and parts loop, there is not in the conventional low thyristor trigger problem that temperature measuring equipment directly is fixed on the thyristor heating radiator, guaranteed the security of electric components, avoided the electric fault generation, in addition, because the output of temperature sensor is linear change, signal conveys is behind universal intelligent temperature digital display instrument, its temperature control point can be set arbitrarily, the temperature control effect has more dirigibility, reach the control temperature, avoid the thyristor in the high-pressure thyristor trigger to damage because of excess temperature, adopt the non-contact type temperature sensor to compare with the contact-type temperature sensor, it has the control dirigibility, safe in utilization, the reliability advantages of higher.
