Technical field
The utility model relates to temperature monitoring and the control of controlled reactor in electric system, belongs to reactor monitoring, opertaing device skill field, specifically a kind of oil immersed type controlled reactor intelligent temperature control equipment.
Background technology
At present, the heat radiation of the controlled reactor moving in low-pressure system mainly relies on cross-ventilation to carry out nature cooling, and controlled reactor can normally be worked under normal circumstances, does not have the phenomenon that heat radiation affects controlled reactor operation.So existing controlled reactor does not mostly relate to the temperature of controlled reactor and controls.
Because 110kV controlled reactor capacity is larger, when reactor long-term work is during in larger capacity, its body oil temperature and winding temperature can raise rapidly, when temperature surpasses certain limit, can affect the normal operation of reactor.In actual use, the winding temperature of controlled reactor can affect the insulativity of winding when approaching or surpassing critical value, and then causes the damage of controlled reactor, even can affect the stable operation of electrical network.And due to the variation of controlled reactor load, the temperature variation of its generation is also different.With reference to the temperature-controlled process of transformer, if drop into when needed the blower fan of fixed qty, carry out coolingly certainly can dealing with problems, but such produced power attenuation is also huge, so be also uneconomic.
Therefore according to load variations, and temperature variation, carry out dynamic switching blower fan and can guarantee that controlled reactor normally works, also can reduce the cooling power consumption of blower fan, improve the serviceable life of blower fan.
Summary of the invention
In view of the problem of above-mentioned existence, the purpose of this utility model is to provide that a kind of control accuracy is high, good economy performance, effective oil immersed type controlled reactor temperature control equipment.
The utility model adopts following technical scheme to address the above problem: a kind of oil immersed type controlled reactor intelligent temperature control equipment, comprise temperature detecting unit, controlled reactor capacity check unit, control module, display unit and blower fan, the output terminal of described temperature detecting unit, controlled reactor capacity check unit is the input end of connection control unit respectively, control module will be given after the temperature signal standardization of detection in temperature monitoring unit, and the output terminal of control module is connecting fan and display unit respectively.
Described temperature detecting unit comprises oil temperature detecting unit, winding temperature detecting unit.
Described controlled reactor capacity check unit is by detection load size of current, for the operation and control of cooling blower provides criterion.
Described blower fan comprises 11 extension sets, is divided into 3 groups, according to the control strategy of control module, selects switching.
Described control strategy is that the duty of blower fan is divided into " RUN ", " assisting ", " standby " three kinds of states, at least guarantees that one group of refrigeratory is in " RUN " state.
Described control module adopts Siemens PLC C as controller.

Compared with prior art, the utlity model has following advantage:
1, the PLC that equipment is applicable to mal-condition use is as controller, and stable performance is controlled, prolonged withstand voltage.
2, according to the operational factor setting and transformer oil temperature instantly, automatically control input and the rotation of blower fan, and the ruuning situation of the feedback air cooling system of having a try.
3, panel adopts touch-screen and pilot lamp display technique, and compatible traditional operating habit, facilitates user scene to check.
The utility model can drop into corresponding blower fan group number according to reactor oil surface temperature, winding temperature and load current size, for oil immersed type controlled reactor provides applicable temperature running environment, effectively improve the operational reliability of oil immersed type controlled reactor, increase the service life.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of oil immersed type controlled reactor intelligent temperature control equipment described in the utility model.
Fig. 2 is the steering logic figure of oil immersed type controlled reactor intelligent temperature control equipment described in the utility model.
Fig. 3 is the structured flowchart of oil immersed type controlled reactor intelligent temperature control equipment described in the utility model.
Embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail:
As shown in Figure 1, oil immersed type controlled reactor intelligent temperature control equipment described in the utility model, comprise temperature detecting unit, controlled reactor capacity check unit, control module, display unit and blower fan, the output terminal of described oil temperature detecting unit, winding temperature detecting unit and controlled reactor capacity check unit is the input end of connection control unit respectively, and the output terminal of described control module connects respectively 11 Fans and display unit.
In specific implementation process, in order better to embody the duty of reactor, temperature measurement signal comprises oil temperature and winding temperature, and in conjunction with the size of load current, determines the duty of blower fan.Temperature detecting unit and capacity check unit will record temperature signal and current signal inputs to control module, control module, through as the control principle of Fig. 2, is exported the control signal to each blower fan, switches the duty of each blower fan.
In Fig. 2, i is oil temperature, and j is winding temperature, and m% is load current percentage.When sensor detect oil surface temperature reach 55 degree more than or winding temperature reach 78 degree more than or load current while reaching 75% ratings, the refrigeratory in secondary status will put into operation; And when oil surface temperature is lower than 45 degree, winding temperature is lower than 68 degree, and during load current blackout, the refrigeratory in secondary status is by out of service.
In the refrigeratory being in operation, have any one group to break down, as electrothermal relay action, isolating switch action etc., the refrigeratory in stand-by state will put into operation, and send " Cooler Fault " signal.When oil surface temperature reaches 70 degree when above, the refrigeratory in stand-by state also will put into operation, far send 70 degree high temperature signals simultaneously in addition.And when oil surface temperature is spent lower than 55, the refrigeratory in stand-by state is by out of service.And " standby " refrigeratory can put into operation by self-timing, to prevent that standby refrigeratory from need not cause breaking down for a long time, thereby affect standby refrigeratory bringing normally into operation when other group faults.
As shown in Figure 3; the employing PLC of control device adds touch screen technology; in conjunction with indicator light switch scleroma point protection technology; the automatic switchover of the startup of Based Intelligent Control blower fan, rotation and power supply; and realize remote transmission device running status and failure alarm signal, reach the object of real-time monitoring, energy-saving safe, prolongation cooling system operation life.
Environmental control system guarantees the ventilation of cabinet, and the humidity of cabinet is controlled, and starts heating when humidity is greater than 80%, lower than 70%, stops heating.Manual control system shows by touch-screen and pilot lamp, can allow user carry out at the scene parameter modification and manually control.Communication system can be isolated repeater remote transfer signal to central control room by RS485, makes operations staff just can recognize the running status of system at central control room.Protection system has phase sequence, open-phase protection, loss protecting and overcurrent protection.
