Equipment run be controlled and manage.Voltage transformer is used to the voltage on conversion line,
It is indispensable device in power system.Nonlinear ferroelectric magnetic characteristic due to voltage transformer
Make voltage transformer produce ferromagnetic resonance, transformer iron core, coil can be caused overheated, Jin Eryin
Playing electrical hazard and fire incident, this just brings great security threat to transformation and distribution system, especially
It is the most prominent for unattended operation transformer station.
Utility model content
The purpose of this utility model be to provide a kind of can the voltage transformer device of temperature measurement on-line,
Solve voltage transformer of the prior art cannot thermometric, lack after its coil is overheated monitoring, hold
The problem easily causing fire incident.
This utility model be the technical scheme is that a kind of can the mutual induction of voltage of temperature measurement on-line
Device device, including voltage transformer body, the binding post of voltage transformer body connects temperature
Sensor, temperature sensor is connected with temperature controller, and temperature controller is connected with PLC,
PLC is connected with alarm device and display the most respectively.
Feature of the present utility model also resides in:
Temperature sensor is contact thermal resistance sensor.
Temperature controller is electronic temperature controller.
The beneficial effects of the utility model are: of the present utility model can the voltage of temperature measurement on-line mutual
Sensor arrangement, by connecting temperature sensor on the winding wiring terminal of voltage transformer, can
Variations in temperature with real-time monitoring voltage transformer；By arranging temperature controller, then arrange
PLC, alarm device and display, it is possible to change to staff's displays temperature in real time, and
To staff's signal an alert when temperature exceedes normal range value, effectively prevent because of voltage
The security incident that mutual inductor coil is overheated and causes.
Accompanying drawing explanation
Fig. 1 is that this utility model is a kind of can the structure of voltage transformer device of temperature measurement on-line
Schematic diagram.
In figure, 1. voltage transformer body, 2. temperature sensor, 3. temperature controller, 4.PLC,
5. alarm device, 6. display.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings:
This utility model a kind of can the voltage transformer device of temperature measurement on-line, as it is shown in figure 1,
Including voltage transformer body 1, the binding post of voltage transformer body 1 connects temperature sensing
Device 2, temperature sensor 2 is connected with temperature controller 3, temperature controller 3 and PLC4 phase
Even, PLC4 is connected with alarm device 5 and display 6 the most respectively.Temperature sensor 2 is for connecing
Touch thermal resistance sensor.Temperature controller 3 is electronic temperature controller.
Electromagnetic potential transformer 1 of the present utility model is on-line operation state, temperature sensor
2 connect and draw on the winding wiring terminal of voltage transformer 1, and temperature sensor 2 induced voltage is mutual
The temperature of sensor 1 coil is also transferred on temperature controller 3, and electronic temperature controller 3 will
Temperature signal is converted to the signal of telecommunication and is transferred on PLC4, and staff can pass through PLC4
The display 6 of upper connection monitors variations in temperature；And when the temperature value measured is more than in PLC4
During set normal temperature value scope, PLC4 sends signal to alarm device 5, dress of reporting to the police
Put 5 to staff's signal an alert.
