Abstract
The utility model provides a temperature controller for a dry type transformer. The temperature controller for the dry type transformer comprises a temperature detecting unit and a control unit. The control unit is connected in sequence with a temperature signal processing unit, a main controller, and a heat dissipation unit which is capable of dissipating heat for a dry type transformer. A monitoring device is connected to the heat dissipation unit. Because the monitoring device is connected to the heat dissipation device, the heat dissipation unit can be monitored, and thus damage to the heat dissipation unit caused by overheating is avoided. Accordingly, the temperature controller for the dry type transformer is safe, reliable, and simple in structure.
Description
Technical field
The utility model relates to a kind of temperature controller, and particularly a kind of temperature controller of dry-type transformer belongs to the technical field of automatic control.
Background technology
Along with the development of social technology, the application of temperature controller of dry type transformer is more and more extensive.The subject matter of temperature controller of dry type transformer is heat dissipation problem in the prior art.At present, the heat radiation of temperature controller of dry type transformer mainly is to rely on cross-ventilation to carry out nature to reduce, and therefore, the operation of equipment is higher to the degree of dependence of physical environment.If running environment can not get control, continue in high temperature, to move, cause easily the damage of temperature controller of dry type transformer.A kind of temperature controller of dry type transformer has appearred recently, comprise temperature detecting unit and control module, control module connects the processes temperature signal unit successively, master controller and the heat-sink unit that can dispel the heat to dry-type transformer, the input end of the processes temperature signal unit in temperature detecting unit and the control module links to each other, the temperature data that the processes temperature signal unit collects temperature detecting unit carries out signal to be processed, signal is sent into master controller, judging whether to start heat-sink unit by master controller dispels the heat to dry-type transformer, but the temperature controller of this structure to heat-sink unit without any monitoring, therefore, dependability is relatively poor.
The utility model content
Technical problem to be solved in the utility model provides a kind of perfect heat-dissipating, temperature controller of dry type transformer safe and reliable and simple in structure.
In order to solve the problems of the technologies described above, a kind of temperature controller of dry type transformer of the utility model, comprise temperature detecting unit and control module, the heat-sink unit that control module connects successively processes temperature signal unit, master controller and can dispel the heat to dry-type transformer, wherein, be connected to supervising device on the described heat-sink unit.
Above-mentioned a kind of temperature controller of dry type transformer, wherein, described supervising device comprises temperature sensor, warning device, and the input end of described temperature sensor links to each other with described heat-sink unit, and output terminal links to each other with described warning device.
Above-mentioned a kind of temperature controller of dry type transformer, wherein, the power end of described dry-type transformer is connected to switching power supply.
Owing to be connected to supervising device on the heat-sink unit, can monitor heat-sink unit, avoid heat-sink unit overheated and damage, thereby, improved safe reliability of the present utility model, and simple in structure.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
In order to solve the problems of the technologies described above, the utility model number a kind of temperature controller of dry type transformer, comprise temperature detecting unit 1 and control module 2, control module 2 comprises temperature controller power supply 20, processes temperature signal unit 21, primary controller 22 and the heat-sink unit 23 that can dispel the heat to dry-type transformer, primary controller 22 is single-chip microcomputer, be connected to supervising device 24 on the described heat-sink unit 23, owing to be connected to supervising device 24 on the heat-sink unit 23, can monitor heat-sink unit 23, avoid heat-sink unit 23 overheated and damage, thereby, improved safe reliability of the present utility model, described supervising device 24 comprises temperature sensor 241, warning device 242, the input end of described temperature sensor 241 links to each other with described heat-sink unit 23, output terminal links to each other with master controller 22 input ends, and the input end of described warning device 242 accesses the output terminal of described master controller 22.Be connected to switching power supply 25 on the described temperature controller power supply 20.This patent has adopted switching power supply 25 and scanning type LED to drive, and greatly reduces the instrument oneself power consumption, has improved the reliability of instrument.The instrument oneself power consumption is about 5W when originally adopting traditional linear stabilized power supply, and input voltage can only be in the 190V-240 scope, the wide region Switching Power Supply that adopts this patent has realized input voltage voltage stabilizing power supply in the 75V-308V wide region, guarantee the normal operation of instrument, drive in conjunction with scanning type LED, this patent has been realized the purpose of Overall Power Consumption less than 1W.
The description of above embodiment is comparatively concrete, detailed; but can not therefore be interpreted as the restriction to this patent scope; should be noted that; for the person of ordinary skill of the art; without departing from the concept of the premise utility; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
