System includes circulation waterway and temperature monitoring device, and the circulation waterway includes inlet and outlet pipe lines and water pump, the inlet and outlet pipe lines
It is connected on the water cooling mouth of thyristor, reactor and capacitor, water pump provides Water circulation hydrodynamics, and the temperature monitoring device includes
Thermal resistance, PLC programmable controller and relay switch, the thermal resistance are placed in thyristor, reactor, capacitor and sensing
On coil, thermal resistance is connected with PLC programmable controller, and PLC programmable controller control relay switch work, relay is opened
The working status of control electric furnace is closed, the temperature signal of measurement is transferred to PLC programmable controller, PLC programmable controls by thermal resistance
Device processed is contrasted temperature signal and setup parameter, and the working status of furnace body is controlled by relay switch.
Beneficial effect
A kind of middle frequency furnace with real-time temperature test sytem of the utility model, compared with prior art the utility model use thermal resistance
Temperature detect switch (TDS) is substituted with PLC programmable controller, and optimizes temperature measuring positions so that monitoring is more accurately and reliably；By with PLC
The display system of programmable controller, can check the temperature of each thermal resistance., can be by checking when temperature occurs abnormal
PLC programmable controller knows the specific location of device fails, greatly facilitates overhaul of the equipments work；The utility model structure is set
Meter is rationally simple and direct, improves the accuracy of system temperature measurement, improves the adjustability and convenience degree of system so that whole process is given birth to
Cost reduction is produced, improves production efficiency, reduces labor strength.
