Description
Technical field
The utility model belongs to temperature automatic control field, particularly the automaton of electric system breaker in middle room temperature.
Background technology
Summer Indoor temperature adds that plug-in unit operation heating temp itself has exceeded the temperature of instructions and regulatory requirements.Nanyue County is in central plain area, and according to meteorological thermograph over the years, winter temperature is all not less than-15 degree, and hyperbaric chamber temperature is not less than 5 degree.The running temperature that summer, hyperbaric chamber temperature required considerably beyond code and instructions, this is the true cause causing the misoperation in summer of microcomputer protective relay plug-in unit.My transformer station of office reduces the method for hyperbaric chamber temperature is at present use exhaust fan, and when morning and evening proper temperature, load are relatively low, exhaust fan runs a large amount of station power consumption of waste continuously, adds production cost.Within 2008, affiliated Transfomer Substation Reconstruction is unattended substation by my office, but hyperbaric chamber fan remains manual operation.Transformer station's quantity is many, and distribution is wide, and operating personnel arrive at a station opening and closing exhaust fan every day, and operating personnel's workload is large, and vehicle expends also high.
Utility model content
To be solved in the utility model is that microcomputer switch gear room now uses manually-operated exhaust fan, and operating personnel's workload is large, and vehicle expends height, energy resource consumption and operating cost high-technology problem.Thus a kind of Microcomputer Protection switch gear room automatic temperature control is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is as follows:
A kind of Microcomputer Protection switch gear room automatic temperature control, comprises control box, is provided with air switch, temperature controller, the first A.C. contactor, the second A.C. contactor, electrothermal relay, temperature sensor and direct current auxiliary reclay in control box; Air switch is connected with temperature controller and the first A.C. contactor respectively; Temperature controller is connected with one end of temperature sensor, pilot lamp and the first A.C. contactor respectively; The other end of the first A.C. contactor is connected with one end of the second A.C. contactor, and the other end of the second A.C. contactor is connected with fan electromotor through electrothermal relay; Direct current auxiliary reclay is connected with the first A.C. contactor, the second A.C. contactor, electrothermal relay and external unit respectively.Direct current auxiliary reclay by external unit (the existing communication control equipment of transformer station) by the Signal transmissions that obtains from the first A.C. contactor, the second A.C. contactor and electrothermal relay to remote monitoring end, make that operations staff is not on-site also can understand fan operation state.
Described control box outer end is provided with pilot lamp, and pilot lamp is connected with temperature controller, and pilot lamp is used to indicate running status.
Described control box outer end is provided with view window, is convenient to observe and operating temperature controller.
The utility model adopts temperature sensor to detect indoor temperature, and detection signal is sent to temperature controller, temperature controller displays temperature, and by the break-make by control first A.C. contactor after signal transacting, controls the start and stop of fan electromotor.Electrothermal relay, by the break-make of control second A.C. contactor, controls the power supply of fan electromotor, and then can protect fan electromotor, prevents fan electromotor overload, phase shortage.There is in control box outer end pilot lamp can intuitively see the utility model running status, can conveniently be observed and operating temperature controller by the view window of control box outer end.The Signal transmissions that obtains from the first A.C. contactor, the second A.C. contactor and electrothermal relay to external unit, can be realized remote monitoring by direct current auxiliary reclay, makes that operations staff is not on-site also can understand this device and fan operation state.The utility model structure is simple, and easy to operate, cost of manufacture is low, can the workload of minimizing operating personnel of high degree, and the operations staff of raising, to the control of fan condition, decreases vehicle and expends, and reduces Energy Consumption Cost and operating cost.Decrease microcomputer protective relay plug-in unit and probability that is abnormal and misoperation occurs, decrease power off time, improve the social credit worthiness of power administration.

Embodiment
Embodiment: as Figure 1-3; a kind of Microcomputer Protection switch gear room automatic temperature control; comprise control box 1, air switch 2, temperature controller 3, A.C. contactor 4 and A.C. contactor 5, electrothermal relay 6, temperature sensor 7, direct current auxiliary reclay 11 are installed in control box 1.
Air switch 2 is connected with temperature controller 3 and A.C. contactor 4 respectively.Temperature controller 3 is connected with one end of temperature sensor 7, red led 8, green indicating lamp 9 and A.C. contactor 4 respectively.The other end of A.C. contactor 4 is connected with one end of A.C. contactor 5.The other end of A.C. contactor 5 is connected with fan electromotor 10 through electrothermal relay 6.Direct current auxiliary reclay 11 is connected with A.C. contactor 4, A.C. contactor 5, electrothermal relay 6 and external unit 12 respectively.The status signal transmission that direct current auxiliary reclay 11 is drawn from A.C. contactor 4, A.C. contactor 5 and electrothermal relay 6, to external unit 12, can realize remote monitoring, makes that operations staff is not on-site also can understand running status of the present utility model.
Be provided with view window in control box outer end, be convenient to observe and operating temperature controller 2.
External unit 12 is the existing communication control equipments of transformer station, can remote reviewing duty of the present utility model.
The course of work: after air switch 2 is closed, temperature controller 2 is energized, when temperature sensor 7 detects that environment temperature rises to setting value, its electric signal transmission to temperature controller 2, temperature controller 2 displays temperature, and signal will be received process, connect A.C. contactor 4, and then connect fan electromotor 10 power supply, fan electromotor 10 is worked, and red led is bright simultaneously.When environment temperature drops to setting value, temperature sensor 7 by detect electric signal transmission to temperature controller 2, temperature controller 2 displays temperature, and the signal received is carried out process rear disconnection A.C. contactor 4, and then disconnect fan electromotor 10 power supply, fan electromotor 10 is quit work, and green indicating lamp 9 is bright simultaneously, and red led 8 goes out.When overload or phase shortage appear in fan electromotor, A.C. contactor 5, under the control action of electrothermal relay 6, disconnects fan electromotor 10 power supply, makes it quit work.
In the whole course of work, the on off operating mode signal that direct current auxiliary reclay 11 will obtain from A.C. contactor 4, A.C. contactor 5 and electrothermal relay 6 all the time, pass to remote monitoring end by external unit 12 status signal, make that operations staff is not on-site also can understand running status.
