Abstract
The invention provides a temperature controller for a dry-type transformer. The temperature controller for the dry-type transformer comprises a temperature detection unit and a control unit. The control unit is sequentially connected with a temperature signal processing unit, a master controller and a radiation unit used for radiation of the dry-type transformer, and a monitoring device is connected to the radiation unit. The monitoring device connected to the radiation unit is capable of monitoring the radiation unit to avoid damage of the radiation unit due to overheat, and accordingly safety reliability of the temperature controller is improved, and the temperature controller for the dry-type transformer is simple in structure.
Description
Technical field
The present invention relates to a kind of temperature controller, 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 dry-type transformer temperature controller more and more widely.The subject matter of dry-type transformer temperature controller is heat dissipation problem in the prior art.At present, the heat radiation of dry-type transformer temperature controller 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 the damage of dry-type transformer temperature controller easily.A kind of dry-type transformer temperature controller has appearred recently; Comprise temperature detecting unit and control module, the input end of the processes temperature signal unit in the heat-sink unit that control module connects processes temperature signal unit, master controller successively and can dispel the heat to dry-type transformer, temperature detecting unit and control module links to each other; The processes temperature signal unit carries out signal Processing to the temperature data that temperature detecting unit collects; Signal is sent into master controller, judge whether to start heat-sink unit by master controller dry-type transformer is dispelled the heat, but the temperature controller of this structure has no monitoring to heat-sink unit; Therefore, dependability is relatively poor.
Summary of the invention
Technical matters to be solved by this invention provides a kind of perfect heat-dissipating, dry-type transformer temperature controller safe and reliable and simple in structure.
In order to solve the problems of the technologies described above; A kind of dry-type transformer temperature controller of the present invention; Comprise temperature detecting unit and control module; The heat-sink unit that control module connects processes temperature signal unit, master controller successively and can dispel the heat to dry-type transformer wherein, is connected to supervising device on the said heat-sink unit.
Above-mentioned a kind of dry-type transformer temperature controller, wherein, said supervising device comprises temperature sensor, warning device, and the input end of said temperature sensor links to each other with said heat-sink unit, and output terminal links to each other with said warning device.
Above-mentioned a kind of dry-type transformer temperature controller, wherein, the power end of said 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 invention, and simple in structure.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
In order to solve the problems of the technologies described above, the present invention's number a kind of dry-type transformer temperature controller comprises 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 a single-chip microcomputer, is connected to supervising device 24 on the said 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, safe reliability of the present invention improved; Said supervising device 24 comprises temperature sensor 241, warning device 242; The input end of said temperature sensor 241 links to each other with said heat-sink unit 23, and output terminal links to each other with master controller 22 input ends, and the input end of said warning device 242 inserts the output terminal of said master controller 22.Be connected to switching power supply 25 on the said 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 operate as normal of instrument, drive that this patent has been realized the purpose of Overall Power Consumption less than 1W in conjunction with scanning type LED.
The description of above embodiment is comparatively concrete, detailed; But can not therefore be interpreted as restriction to scope; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the present invention's design; Can also make some distortion and improvement, these all belong to protection scope of the present invention.
