Abstract
The invention relates to an intelligent temperature control instrument of a dry type transformer, comprising a temperature acquiring module, a single chip microcomputer control module, a temperature setting module, an automatic tripping module and a transformer cooling fan; the single chip microcomputer control module is respectively connected with the temperature acquiring module, the temperature setting module, the automatic tripping module and the transformer cooling fan; and the intelligent temperature control instrument of the dry type transformer also comprises an LED temperature display module connected with the single chip microcomputer control module and an automatic alarming module connected with the automatic tripping module. By using the intelligent temperature control instrument of the dry type transformer, the problem of incapacity of accurately controlling the work temperature of the transformer in the prior art is solved, the temperature control of the dry type transformer is realized, and automatic tripping, cutting off the transformer and alarming are realized when the temperature of the transformer is higher than a warning temperature, so that the reliability for the operation of the dry type transformer is improved, and the service life of the dry type transformer is prolonged.
Description
Technical field
The present invention relates to a kind of dry-type transformer temperature intelligent controller, belonged to electronic technology field.
Background technology
At present; The heat radiation of dry-type transformer mainly is to rely on cross-ventilation to carry out the nature cooling; Temperature-fall period is higher to the environment degree of dependence around the dry-type transformer; Temperature is controlled accurately in the time of can't moving it; When the environment around the transformer was unfavorable for its cooling, transformer just can move under hot soak condition, and the operational reliability of transformer is reduced greatly; And for a long time shortened the serviceable life of transformer, even can cause permanent damage greatly.So guarantee the operation of dry-type transformer normal reliable, just need carry out radiating treatment to it, accurately control its temperature.
Summary of the invention
In order to solve the problems of the technologies described above; The invention provides a kind of dry-type transformer temperature intelligent controller, when the temperature of transformer was higher than design temperature, the starting transformer refrigeration fan was lowered the temperature to it; When the transformer temperature is higher than the warning temperature, realize automatic trip disconnection transformer.
To achieve these goals, the technical scheme that the present invention adopted is: a kind of dry-type transformer temperature intelligent controller comprises temperature collect module, single chip control module, temperature setting module, automatic trip module and transformer refrigeration fan; Said single chip control module is connected with temperature collect module, temperature setting module, automatic trip module, transformer refrigeration fan respectively.
Aforesaid a kind of dry-type transformer temperature intelligent controller is characterized in that: also comprise a LED temperature display module that is connected with single chip control module.
Aforesaid a kind of dry-type transformer temperature intelligent controller is characterized in that: also comprise an automatic alarm module that is connected with the automatic trip module.
Aforesaid a kind of dry-type transformer temperature intelligent controller, it is characterized in that: the Temperature sampler that described temperature collect module uses is the PT100 platinum resistance.
The invention has the beneficial effects as follows: realized temperature control dry-type transformer; When the transformer temperature that collects when temperature collect module is higher than design temperature; Through single chip control module starting transformer refrigeration fan it is lowered the temperature; When the transformer temperature that collects is higher than the warning temperature; Realize automatic trip disconnection transformer; And report to the police, improved the reliability when dry-type transformer moves, prolonged the life-span of dry-type transformer.
Description of drawings
Fig. 1 is that the module of dry-type transformer temperature intelligent controller connects synoptic diagram.
Embodiment
To combine Figure of description below, the present invention is further illustrated.
Shown in Fig. 1, a kind of dry-type transformer temperature intelligent controller comprises temperature collect module 2, single chip control module 1, temperature setting module 3, automatic trip module 5 and transformer refrigeration fan 4; Said single chip control module 2 is connected with temperature collect module 1, temperature setting module 3, automatic trip module 5, transformer refrigeration fan 4 respectively; The LED temperature shows that 6 of moulds are connected with single chip control module 1, and automatic alarm module 7 is connected with automatic trip module 5; The temperature sensor that temperature collect module 2 adopts is the PT100 platinum resistance.
When dry-type transformer is worked; Set a refrigeration fan start-up temperature and a warning temperature by the temperature setting module; Utilize the PT100 RTD that the temperature of the transformer that collects is transferred to single chip control module 1; The information via that single chip control module 1 collects temperature sensor is handled the back and is compared with the temperature of setting; When the temperature of transformer is higher than design temperature; The starting transformer refrigeration fan is lowered the temperature to it; When the transformer temperature is higher than the warning temperature; Realize automatic trip disconnection transformer by automatic trip module 5, and start warning devices by automatic alarm module 7.Wherein, the temperature of the transformer of the refrigeration fan start-up temperature of setting, warning temperature and collection all shows concrete temperature value through LED temperature display module 6.
In sum; A kind of dry-type transformer temperature intelligent controller provided by the invention; Realization is to the temperature control of dry-type transformer; When the transformer temperature is higher than the warning temperature; But transformer is broken off in automatic trip; And report to the police, improved the reliability when dry-type transformer moves, prolonged the life-span of dry-type transformer.
More than show and described ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the instructions just illustrates principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention; The present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain by appending claims and equivalent circle thereof.
