Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Wind turbines embodiment
The Wind turbines that the utility model provides, comprises circuit heating supervisory system in the power circuit in tower cylinder, tower cylinder and tower of wind generating set cylinder as shown in Figure 1.Supervisory system comprises temperature sensor and smoke transducer, and wherein temperature sensor is divided into several groups, often comprises several temperature sensors in group, often organizes the corresponding smoke transducer of temperature sensor.As a kind of embodiment, in the present embodiment, temperature sensor is divided into 4 groups, often has 8 temperature sensors in group.
Wherein, temperature sensor can be numeric type 18B20 series temperature probe, and also can select thermal resistance temperature sensor, can also be the temperature sensor of other types.In actual applications, need the cable insulation surface be pasted onto by heat-conducting silicone grease by temperature probe in tower cylinder, consider generally, the temperature of cable connecting part position is relatively high, so paste position near cable splice, should be specially the region in distance joint 10cm.Further, because MW level blower fan electric current is larger, every phase power cable is all by multi-cable parallel arranged, now monitors also unrealistic to the temperature of every root cable.Therefore, as a kind of embodiment, in order to reduce the quantity of temperature probe, be pasted onto by temperature probe in the middle of cable, can realize measuring the temperature of multi-cable, particular location as shown in Figure 2.But every phase power cable is owing to comprising multi-cable parallel arranged, and a temperature probe effectively can not detect a cable splice, so, need above-mentioned one group of temperature probe to detect place's cable splice simultaneously.
In addition, when Wind turbines power cable is due to the overheated and initiation fire of cable, its insulation course can produce a large amount of dense smoke, consider the chimney effect of tower cylinder, therefore can consider that about 50cm installs a smoke transducer near the position of cable above cable splice, when having detected that smog occurs, export an on-off model.
This supervisory system also comprises device for detecting temperature, and this device for detecting temperature is the device of signals collecting and rough handling, and it is the unit of the comparison core of whole supervisory system.Device for detecting temperature can be added by general micro-chip processor that peripheral signal conditioning circuit forms.And because tower cylinder internally-powered cable is that multistage is formed by connecting, therefore need to monitor the electric cable heating situation of each interface, this just needs multiple device for detecting temperature.The corresponding one group of temperature probe of each device for detecting temperature and smoke transducer.
The temperature signal that one group of temperature probe records, after a device for detecting temperature process, is converted to actual temperature value; Meanwhile, the on-off model of smog that smoke transducer detects also will be input in this device for detecting temperature.The output terminal of all device for detecting temperature is connected on a fieldbus, the signal input part of this fieldbus connecting fan main control PLC.The field bus communication agreement of the equal built-in general-purpose of each device for detecting temperature, can be uploaded to the data message received in blower fan main control PLC by this agreement by fieldbus.In addition, the power supply of each device for detecting temperature can be 230AC, can be also 24VDC, specifically need select according to on-site actual situations.
The address of device for detecting temperature can be set to different address, and eventually through field bus protocol networking, is connected with blower fan main control PLC by fieldbus, and wherein device for detecting temperature is substation, and blower fan main control PLC is main website.In order to ensure that cable temperature situation of change and smoke condition can be seen in real time in monitoring backstage, also can pass through wind field SCADA system, data being sent to wind energy turbine set monitoring backstage---Central Control Room.
In this tower of wind generating set cylinder, circuit heating supervisory system is when carrying out cable monitoring:
Step 1: the temperature sensor fixing right quantity every section of cable connecting part position according to the mode of Fig. 2, and above cable connecting part position, smoke transducer is installed;
Step 2: one group of temperature sensor and a smoke transducer are accessed in the device for detecting temperature of the correspondence be fixed on tower barrel respectively, can realize collecting with cigarette information of having generated heat the temperature information of tower cylinder power cable by device for detecting temperature, and make preliminary information processing;
Step 3: by the mode of fieldbus, uploads in blower fan main control PLC by the tower cylinder power cable temperature information in all device for detecting temperature and smoke signal in real time;
Step 4: in fan operation process, the temperature of blower fan main control PLC meeting Real-Time Monitoring tower cylinder power cable and smoke signal, if the temperature that main control PLC monitors certain temperature sampling point is greater than a threshold value, or smoke transducer has detected smog information, then can automatically control blower fan to shut down, power cable will be cut off power supply, thus stops fire generation or continue to spread; Meanwhile, this information is uploaded to monitoring by wind energy turbine set SCADA supervisory system, and backstage---in Central Control Room, background work personnel can check tower cylinder power cable temperature conditions, and make and correspondingly processing.
In above-described embodiment, controller adopts PLC, as other embodiment, can also adopt the controller of other types, such as: single-chip microcomputer.
In above-described embodiment, give the set-up mode of the fixed position of temperature probe under different cable arrangements mode, this is just in order to reduce the quantity of temperature probe and a kind of embodiment of optimization made, and as other embodiment, the equal correspondence of each cable is provided with a temperature probe.
In above-described embodiment, all device for detecting temperature pass through a fieldbus by information transmission to controller, this is a kind of embodiment of optimization, certainly, the utility model is not limited to above-described embodiment, and as other embodiment, each device for detecting temperature is connection control device all directly, the input port of controller can be increased like this, but also can implement.Further, device for detecting temperature can not also be arranged, temperature sensor and the direct connection control device of smoke transducer.
In above-described embodiment, temperature sensor is divided into some groups, often organize that temperature sensor is corresponding with smoke transducer to be arranged, the utility model is not limited to above-described embodiment, a not unique mode between temperature sensor and the number of smoke transducer, such as: temperature sensor can be identical with the number of smoke transducer.
