The communication module and the analog quantity output module ensure that the temperature controller can transmit temperature signals and switching-value electrical signals to external remote equipment in real time, wherein when networking management is carried out on the dry type transformer temperature controller, a user can set parameters and carry out remote control on different fixed temperature values of the whole network, so that automatic control is realized; and the control module can control blowing rate of a fan.
Description
Technical field
The utility model relates to the Dry-Transformer Technology field, is specifically related to a kind of instrument that the dry-type transformer temperature is controlled.
Background technology
The dry-type transformer temperature controller is that a kind of measuring transformer internal temperature of microprocessor formation that utilizes is to reach the measure and control device of the purpose of controlling temperature.Because it has characteristics such as high stability, high automation, the dry-type transformer temperature controller is obtaining utilization widely aspect the temperature protection of dry-type transformer.
At present, though traditional display type dry-type transformer temperature controller is well positioned to meet numerous terminal users' general requirements, but still have the following disadvantages: traditional display type dry-type transformer temperature controller has only the function of demonstration, alarm and tripping operation, and do not control the function of blower fan, can not satisfy user's multiple demand, and be difficult to satisfy present robotization requirement; Traditional display type dry-type transformer temperature controller can not be realized information-based and networked because of the restriction of its hardware platform well.Therefore, present employed display type dry-type transformer temperature controller has been difficult to satisfy users' intellectuality, networked requirement.
The utility model content
At above-mentioned deficiency of the prior art, the dry-type transformer temperature controller that the utility model provides has solved the problem that temperature controller can not be controlled blower fan and can not export remote transfer signal.
In order to reach the foregoing invention purpose, the technical solution adopted in the utility model is for providing a kind of dry-type transformer temperature controller, and it comprises CPU module, the acquisition module that is connected with the CPU module respectively, control module, communication module, analog output module, man-machine interface circuit and memory module.
Further, described acquisition module comprises temperature collect module and the switching value signal acquisition circuit that is connected with the CPU module respectively.
Further, described man-machine interface circuit comprises alarm module, pilot lamp, control button and the charactron that is connected with the CPU module respectively.
Further, described control module is several relays that are connected with the CPU module.
Further, described communication module is 485 communication modules or 232 communication modules.
Further, described temperature collect module comprises temperature sensor and signal conversion module, and described signal conversion module is connected with the CPU module with temperature sensor respectively.
Further, described alarm module is hummer.
The beneficial effects of the utility model are: the communication module of increase and analog output module have guaranteed that temperature controller can be in real time gives peripherals with temperature signal and switching value electrical signal transfer, when the dry-type transformer temperature controller is carried out the networking management, the user can set and remote control by all temps definite value of whole networking being carried out parameter, makes things convenient for realization of automatic control; The setting of control module has solved temperature controller of the prior art and can not control the problem of dry-type transformer being carried out air-cooled blower fan unlatching; This temperature controller is high in when operation stability, and its hardware is tested and safeguarded and can test and safeguard by functions of modules, has reduced maintenance cost, has improved work efficiency, and it also has low in energy consumption, intellectuality and steady performance.
