Abstract
The name of the utility model is a high voltage liquid resistance temperature measurement mechanism, pertaining to the technical field of high voltage liquid resistance temperature measurement. The utility model mainly solves the problem that the prior liquid resistance temperature measurement mechanism can not measure the high voltage liquid resistance temperature and the utility model is characterized in that a temperature display instrument, a heat pipe and an infrared temperature transmitter fixed on a cover board of a liquid resistance box body are included, a collecting plate arranged at the upper end of the heat pipe, the lower end of the heat pipe extends into the liquid resistance; and the infrared temperature transmitter is arranged directly above the collecting plate. The utility model can realize resistance temperature measurement of liquid resistors used for starting voltage reduction of larger and medium high voltage electric motors and has the advantages of quick response, small volume, reliable operation, high security and accurate temperature measurement. The utility model is essentially applied for measurement of liquid resistance temperature of high voltage liquid resistance starters.
Description
Technical field
The utility model relates to a kind of liquid resistance temperature measuring equipment, particularly a kind of highly pressurised liquid resistance temperature measurement mechanism that is used for the big-and-middle-sized AC motor reduced voltage starting of high pressure, and the while also can be used for the contact-free measurement of temperature of other liquid medium.Belong to highly pressurised liquid resistance temperature field of measuring technique.
Background technology
At present the thermometric measuring method commonly used of liquid resistance has two kinds: a kind of method is that insulating sleeve inserts in the liquid resistance and measures with the temperature sensor insulating sleeve of packing into, and slow in reacting when this kind method is measured temperature, error is very big; Another kind method is the outer wall that temperature-sensing element (as platinum resistance) is attached to the liquid tank material, and this kind method also has very big drawback, and is big as the temperature detection error, the temperature detection time lag is big etc., can not reflect the true temperature of liquid resistance in real time accurately.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of highly pressurised liquid resistance temperature measurement mechanism of measuring highly pressurised liquid resistance starter liquid resistance temperature at above-mentioned weak point.
Technical solution of the present utility model is: a kind of highly pressurised liquid resistance temperature measurement mechanism, comprise temperature indicator, it is characterized in that: also comprise the heat pipe that is fixed on the liquid resistance box cover, this heat pipe upper end is provided with the thermal-arrest plate, and the lower end extend in the liquid resistance; Directly over the thermal-arrest plate, be provided with infrared temperature sensor.
The utility model is owing to adopt heat pipe and infrared temperature sensor, and heat pipe is fixed on the liquid resistance box cover, its upper end is provided with the thermal-arrest plate, the lower end extend in the liquid resistance, infrared temperature sensor be arranged on the thermal-arrest plate directly over, thereby, but the temperature that the heat pipe flash heat transfer makes heat pipe top thermal-arrest plate is consistent with the temperature that heat pipe is immersed in liquid resistance the inside part, infrared temperature sensor just can directly record the temperature of thermal-arrest plate, is the temperature of liquid resistance.The utility model can be realized the resistance temperature measurement of high pressure large and medium motor reduced voltage starting with liquid resistor, have fast, little, reliable, safe, the accurate characteristics of temperature survey of volume of responding, can reflect the true temperature of liquid resistance in real time accurately, overcome the deficiencies in the prior art part.The utility model is mainly used in the measurement of highly pressurised liquid resistance starter liquid resistance temperature.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in the figure.Infrared temperature sensor 3 is fixedly mounted on the fixed support 2, and fixed support 2 then is fixed on the skeleton 1 of thermistor.The heat pipe 5 of conductive liquid resistance 6 temperature is fixed on the cover plate 4 of resistor fluid casing by the thermal-arrest plate 7 on its top.The axle center of infrared temperature sensor 3 and the axle center of heat pipe are on same the pedal line, wherein the thermal-arrest plate 7 of the axle center of infrared temperature sensor 3 and heat pipe upper surface is approximated to 90 degree, and the vertical range of the thermal-arrest plate of the upper surface of infrared temperature sensor 3 and heat pipe 5 should meet the requirement of infrared temperature sensor 3, and assurance is reflected to the temperature of the thermal-arrest plate end face of heat pipe 5 in the sensor really.The temperature signal that infrared temperature sensor 3 records is sent into temperature indicator, just can the temperature of liquid resistance be shown in real time.The excellent properties of heat pipe 5 flash heat transfers makes that the temperature of heat pipe top thermal-arrest plate is consistent with the temperature that heat pipe is immersed in liquid resistance the inside part, and the temperature of liquid resistance can be transmitted on the thermal-arrest plate 7 of heat pipe 5 apace.Infrared temperature sensor 3 also keeps enough electrical safety distances with other conducting positions of heat pipe 5 and thermistor, can guarantee the electrical security of temperature measuring equipment like this.
