Abstract
The utility model discloses a dry-type transformer temperature controller, comprising a temperature detection unit and a control unit. The control unit is connected with a temperature signal processing unit, a main controller and a heat dissipation unit which cools a dry-type transformer in sequence. The temperature detection unit is built in with temperature sensors which are connected with an input end of the temperature signal processing unit. The temperature signal processing unit is built in with a signal amplifier and an A/D convertor. The temperature signal processing unit performs signal processing on acquired temperature data, and transmits signals into the main controller. The main controller determines whether to start the heat dissipation unit or not to cool the dry-type transformer. The main controller is connected with a high-temperature alarm unit, a high-temperature tripping unit, a keyboard and a display. The dry-type transformer temperature controller can be used to monitor and control oil temperature of the dry-type transformer and provide proper temperature of operating environment for the dry-type transformer, so that reliability of power supply is improved.
Description
Technical field
The utility model relates to the automatic control technology field, relates in particular to a kind of temperature controller of dry type transformer.
Background technology
At present, the heat radiation of dry-type transformer is mainly carried out the nature cooling by cross-ventilation, service condition is higher to the environment degree of dependence, if running environment can not get controlling, use in high temperature lastingly, the operational reliability of transformer is reduced greatly, and so can make the lost of life of transformer for a long time, perhaps cause permanent damage.So guarantee the reliability service of dry-type transformer, the oil temperature of monitoring and control dry-type transformer seems particularly important, needs a kind of temperature controller that the dry-type transformer oil temperature is monitored and controlled at this.
Summary of the invention
The purpose of this utility model is to provide a kind of temperature controller of dry type transformer, is used for monitoring and controls the dry-type transformer oil temperature, for dry-type transformer provides suitable temperature running environment, improves power supply reliability.
For achieving the above object, the technical solution of the utility model is: a kind of temperature controller of dry type transformer, comprise temperature detecting unit and control module, the heat-sink unit that described control module connects successively processes temperature signal unit, master controller and can dispel the heat to dry-type transformer, described temperature detecting unit built-in temperature sensor is connected with the input end of processes temperature signal unit; Described processes temperature signal unit built-in signal amplifier and A/D converter, the temperature data that temperature detecting unit is collected carries out the signal processing, signal is sent into master controller, judge whether to start heat-sink unit by master controller dry-type transformer is dispelled the heat.
Further, described master controller also connects high temperature alarm unit, high temperature trip unit, keyboard and display.
Temperature controller of dry type transformer of the present utility model can be used for monitoring and controls the dry-type transformer oil temperature, for dry-type transformer provides suitable temperature running environment, improves power supply reliability.
