Abstract
The utility model relates to a control by temperature change sensor for transformer, it includes sensor overcoat, sensor endotheca, heater strip dabber and connecting rod, the embedded dress platinum resistance of heater strip dabber, heater strip dabber outer wall winding installation heater strip, the outside suit sensor endotheca of heater strip dabber, the outer cavity of confined is formed with the sensor overcoat to the sensor endotheca, the internal temperature sensing medium that is full of of exocoel, the sensor overcoat links to each other with the connecting rod. The utility model discloses be full of the temperature sensing medium in the cavity, when the temperature variation, temperature sensing medium volume changes and drives the diaphragm chamber body and produce the displacement, and when cavity same volume, the surface area has increaseed, has changed the heat transfer area of sensor for heat exchange efficiency increases substantially, and then has improved the sensitivity of temperature controller.
Description
Technical field
The utility model relates to a kind of temperature control sensor, particularly relates to a kind of transformer temperature control sensor.
Background technology
Transformer, in operational process, needs to monitor temperature.Temperature control sensor, normally by the change of the reacting condition temperature of thermistor, realizes temperature and controls.But in prior art, be not very desirable with temperature control sensor sensitivity on the transformer, and by the impact that ambient temperature changes.
Utility model content
The utility model is for above-mentioned problems of the prior art, provide a kind of transformer temperature control sensor, solve prior art medium sensitivity problem that is poor, that affect by ambient temperature, by the design effect of realization expection that application the utility model structure can be simple and quick.
Technical solutions of the utility model are as follows:
Temperature control sensor comprises sensor overcoat, sensor inner sleeve, heater strip mandrel and connecting link, setting-in platinum resistance in heater strip mandrel, heater strip mandrel outer wall is wound around installs heater strip, the outside suit sensor inner sleeve of heater strip mandrel, sensor inner sleeve and sensor overcoat form the outer chamber closed, be full of temperature sensing medium in outer chamber, sensor overcoat is connected with connecting link.
Be provided with filling orifice bottom described heater strip mandrel, transformer oil enters sensor inner chamber by filling orifice.
Described heater strip mandrel is provided with heater strip welded disc.
One end of described outer chamber is connected with bellows body by kapillary.
Described platinum resistance is Pt100 platinum resistance.
Advantage of the present utility model and good effect are:
1, be full of temperature sensing medium in cavity, when the temperature is changed, temperature sensing medium volume changes and drives bellows body to produce displacement, when cavity volume is identical, surface area increases, and changes the heat interchanging area of sensor, heat exchange efficiency is increased substantially, and then improves the sensitivity of temperature controller.
2, heater strip is embedded in sensor inner chamber body, improves heat exchange efficiency again not by the impact of variation of ambient temperature.
3, setting-in Pt100 platinum resistance in heater strip mandrel, the compound achieving signal becomes to be sent.
Meanwhile, the utility model structure is simple, and dependable performance is easy for installation, applied range.
