Description
Technical field
The utility model is related to a kind of temperature controllers, and in particular to a kind of temperature controller applied to compensating cabinet.
Background technology
With the fast development of China's accession to WTO and national economy, Chinese generated energy persistently keeps high speedup shape
State, Chinese electricity consumption occupy the first in the world.According to Xinhua News Agency, on July 15th, 2015, National Energy Board issued on 2015
The national electricity consumption of half a year adds up 2,662,400,000,000 kilowatt hours, increases by 1.3% on a year-on-year basis.National generating equipment is accumulative to be averagely using hour
1936 hours.According to another Xinhua News Agency's Chongqing channel September 22 days, global electricity consumption in 2015 increased to 6,000,000,000,000 kilowatt hours, intelligence electricity
Net expects development.Under such overall situation, efficient and rational utilize of power grid is particularly important.Power grid can be efficiently sharp
With, can what be seen be exactly that reach stable operation, since inductance uses more, power factor reduction to power grid in actual operation,
Reactive power is larger for power grid, needs to use compensating cabinet at this time by power factor tune up, therefore compensating cabinet just seems outstanding
It is important.
Currently, existing compensating cabinet, when carrying out switching, capacitance, which is easy fever, influences switching, to influence the work(of compensating cabinet
Can, thus need the bulk temperature for controlling compensating cabinet.Therefore, it is necessary to a kind of technical solution be provided, to lower the whole of compensating cabinet
Temperature reaches the monolithic stability operation of compensating cabinet.
Utility model content
In order to overcome the deficiencies of the prior art and there are the problem of, the utility model provides a kind of temperature controller, to control
The bulk temperature of compensating cabinet processed reaches the purpose of monolithic stability operation.
The utility model is achieved through the following technical solutions：A kind of temperature controller comprising temperature sensor K,
One end of intermediate relay KA1 and intermediate relay KA2 and wind turbine M, the temperature sensor K by stop button SB1 with
The other end of power input L connections, the temperature sensor K is connected by the coil of intermediate relay KA2 with power input N
It connects, one end of the wind turbine M is connect by the normally opened contact of intermediate relay KA2 with the stop button SB1, the wind turbine M
The other end connect with power input N, one end of the coil of the intermediate relay KA1 by start button SB2 with it is described
Stop button SB1 connections, the other end of the coil of the intermediate relay KA1 are connect with power input N, the intermediate relay
One end of the normally opened contact of device KA1 is connect with the stop button SB1, the normally opened contact of the intermediate relay KA1 it is another
End is then connected between the coil of intermediate relay KA1 and the start button SB2.
Further, the normally opened contact of the intermediate relay KA1 also passes through a run indicator HR and power input
Hold N connections.
Preferably, the stop button SB1 is connect by fuse FU1 with power input L.
It, can be well to the whole temperature of compensating cabinet when temperature controller provided by the utility model is applied to compensating cabinet
Degree is controlled, so that the operation of compensating cabinet is more stablized；And the temperature controller has circuit structure simple, it is practical
The advantages that property is strong.
Description of the drawings
Fig. 1 is the electrical block diagram of temperature controller described in the utility model embodiment.
Specific implementation mode
For the ease of the understanding of those skilled in the art, below in conjunction with the drawings and specific embodiments to the utility model make into
One step is described in detail.
As shown in Fig. 1, a kind of temperature controller comprising temperature sensor K, intermediate relay KA1 and intermediate relay
One end of device KA2 and wind turbine M, the temperature sensor K are connect by stop button SB1 with power input L, the temperature
The other end of sensor K is connect by the coil of intermediate relay KA2 with power input N, during one end of the wind turbine M passes through
Between the normally opened contact of relay KA2 connect with the stop button SB1, the other end and the power input N of the wind turbine M connect
It connects, one end of the coil of the intermediate relay KA1 is connect by start button SB2 with the stop button SB1, the centre
The other end of the coil of relay KA1 is connect with power input N, one end of the normally opened contact of the intermediate relay KA1 with
The stop button SB1 connections, the other end of the normally opened contact of the intermediate relay KA1 are then connected to intermediate relay KA1
Coil and the start button SB2 between.Wherein, the power input L in the present embodiment refers to the firewire wiring in power supply
End, and power input N refers to then the zero curve terminals in power supply.
Preferably, the stop button SB1 is connect by fuse FU1 with the power input L, it should by setting
Fuse FU1 can play the role of effective protection temperature controller.
As preferred embodiment, the normally opened contact of the intermediate relay KA1 also by a run indicator HR with
Power input N connections, run indicator HR, for the operating status display lamp as temperature controller.
Illustrate the course of work of temperature controller provided in this embodiment briefly below：
The temperature controller is applied in compensating cabinet, when pressing start button SB2, the line of intermediate relay KA1
Enclose electric, run indicator HR obtains electric bright, and intermediate relay KA1 normally opened contacts are connected, circuit self-locking, and run indicator HR is normal
It is bright；When the temperature of compensating cabinet reaches the critical closing point of temperature sensor K, intermediate relay KA2 coils obtain electric, intermediate relay
The normally opened contact of KA2 becomes normally closed by normally opened, and wind turbine M obtains electricity operation, so that the temperature of compensating cabinet reduces, reaches cooling effect
Fruit；When the temperature of compensating cabinet reduces to a certain extent, temperature sensor K is disconnected, to make due to expanding with heat and contract with cold by being closed into
Wind turbine M power-off is out of service, the temperature of compensating cabinet can be gradually increasing；And after pressing stop button SB1, temperature controller is disconnected
Electricity is stopped, and run indicator HR extinguishes.Using the temperature controller, the bulk temperature of compensating cabinet can be carried out well
Control, so that the operation of compensating cabinet is more stablized；And it has many advantages, such as that circuit structure is simple, it is highly practical.
Above-described embodiment is the preferable realization method of the utility model, is not the restriction to the utility model, not
Be detached from the utility model inventive concept under the premise of, it is any it is obvious replacement the scope of protection of the utility model it
It is interior.
