Abstract
The utility model provides a starting device of a low-temperature type variable pitch control system. With ingenious connection of a temperature sensor, a time relay and a relay contactor, when ambient temperature is very low and a heater heats the temperature to rise to meet the starting condition of the system, normal start is allowed after delaying for a period of time; and when the ambient temperature meets the starting condition, the system can operate directly without need of delaying for 60 minutes. The starting device has the main benefits of saving a large quantity of power generating time and greatly improving power generating efficiency.
Description
Technical field
The utility model relates to a kind of starting drive of low-temperature type paddle change control system, belongs to the wind power technology field.
Background technique
At present, in variable blade control system,, mainly be divided into two classes by the temperature classification of type: the one, the normal temperature type variable blade control system; The 2nd, low-temperature type paddle change control system.
As shown in Figure 1, when low-temperature type paddle change control system moves in system, can monitor in real time ambient temperature, be that system comprises a temperature transducer T, when temperature met starting condition, promptly ambient temperature was greater than 5 degree, and time relay T1 time-delay is after 60 minutes, it is electric that relay K 3 is got, system's operation.When temperature transducer T detects ambient temperature and spends less than 5, relay K 4 electric, heater heats is heated to when spending greater than 5, time relay T1 time-delay is after 60 minutes, the repeated priming process makes system's operation.In the present employed low-temperature type paddle change control system, no matter ambient temperature is greater than 5 degree or less than 5 degree, after time relay T1 needed to delay time 60 minutes, system could move.
The main purpose that system delay starts is for the electric components in the control casing can be used in the temperature range that allows, when ambient temperature is very low, when the heater heats temperature rises to the compliance with system starting condition, because the thermal conductivity of electric components is slow, could normally start after a period of time that needs to delay time; And when ambient temperature met starting condition, system reruned after not needing to delay time 60 minutes, so prior art wasted the plenty of time, had influenced the efficient of generating greatly.
The model utility content
The purpose of this utility model is to solve above-mentioned technical problem, and a kind of starting drive of more efficiently low-temperature type paddle change control system is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of start device of low-temperature type paddle change control system comprises:
The interconnective temperature transducer T and first relay K 1 and the 4th relay K 4, described first relay K 1 is connected with heater with the 4th relay K 4, is respectively applied for to close or start heater;
And interconnective time relay T1 and the 3rd relay K 3,
Also comprise the 5th relay K 0 and second relay K 2;
The normal-closed end of described the 5th relay K 0 is connected with described temperature transducer T;
The normal-closed end of described second relay K 2 is connected with the Chang Kaiduan of described first relay K 1;
Described second relay K 2 Chang Kaiduan be connected with the Chang Kaiduan of described the 5th relay K 0, and link to each other with time relay T1;
The Chang Kaiduan of described the 5th relay K 0 and described second relay K 2 the normal-closed end interlocking be connected;
Described time relay T1 is connected with the 3rd relay K 3 that is used to start variable blade control system.
The beneficial effects of the utility model are mainly reflected in: save a large amount of generating dutations, improve generating efficiency greatly.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1: the schematic representation of prior art start device of low-temperature type paddle change control system.
Fig. 2: the schematic representation of the utility model start device of low-temperature type paddle change control system.
Embodiment
The utility model has disclosed a kind of start device of low-temperature type paddle change control system, as shown in Figure 2, comprise: the interconnective temperature transducer T and first relay K 1 and the 4th relay K 4, described first relay K 1 is connected with heater with the 4th relay K 4, is respectively applied for to close or start heater; And interconnective time relay T1 and the 3rd relay K 3.
Described start device of low-temperature type paddle change control system also comprises the 5th relay K 0 and second relay K 2; The normal-closed end of described the 5th relay K 0 is connected with described temperature transducer T; The normal-closed end of described second relay K 2 is connected with the Chang Kaiduan of described first relay K 1; Described second relay K 2 Chang Kaiduan be connected with the Chang Kaiduan of described the 5th relay K 0, and link to each other with time relay T1; The Chang Kaiduan of described the 5th relay K 0 and described second relay K 2 the normal-closed end interlocking be connected; Described time relay T1 is connected with the 3rd relay K 3 that is used to start variable blade control system.
Working procedure of the present utility model is once simply described below:
When low-temperature type paddle change control system moved in system, temperature transducer T can monitor in real time to ambient temperature.
When temperature meets starting condition, be that temperature transducer T is when detecting ambient temperature and spending greater than 5, the 5th relay K 0, since the Chang Kaiduan of the 5th relay K 0 and described second relay K 2 the normal-closed end interlocking be connected, therefore the 3rd relay K 3 must be electric, and variable blade control system is started.And simultaneously,, time relay T1 is not also worked because second relay K 2 must not be electric, therefore under this temperature conditions, system start-up can not delayed time 60 minutes.
When temperature transducer T detects ambient temperature and spends less than 5, relay K 4 electric, start heater heats, be heated to when spending greater than 5, first relay K 1 electric, close heater, second relay K 2 also simultaneously.And this moment, temperature transducer T detected ambient temperature less than 5 degree, thus the 5th relay K 0 also electric, thereby can make time relay T1 get electric work like this.Since this moment second relay K 2 electric, its normal-closed end can disconnect successively, therefore can not make the 3rd relay K 3 at once.And can be after time-delay 60 minutes, it is electric that the 3rd relay K 3 is got, and then variable blade control system is started.
The utility model still has multiple concrete mode of execution.All employings are equal to replacement or equivalent transformation and all technological schemes of forming, all drop within the claimed scope of the utility model.
