A control method for the soft starter heat radiation fan is characterized in that, a microprocessor of a soft starter outputs high and low levels to respectively control conduction and cut-off of a triode, thereby controlling pull-in and release of a relay K3, a pull-in joint of the relay K3 is connected to a socket JX4, and two pins of the socket JX4 are connected to a main board of the soft starter to take electricity. Due to the above circuit structure, the control method is provided with the following advantages: 1. no need of external power supply, electricity taking via the main board of the soft starter; 2. heat radiation effect upon a thyristor and prevention of a traditional soft starter heat radiation fan from always being in a running state; and 3. reduction of damage rate of the heat radiation fan, and power saving.
Description
Technical field
The utility model relates to soft starter, particularly a kind of soft starter radiation fan.
Background technique
As motor control assembly, soft starter adopts the three-phase anti-parallel thyristor to complete the control to motor as pressure governor.Due to soft starter, in starting process, the three-phase anti-parallel thyristor has large electric current to pass through, and causes it hot, therefore needs radiation fan to be dispelled the heat.
Current soft starter radiation fan needs independently Power supply, and the soft starter radiation fan is always in running state.In running state, can strengthen the damage probability of soft starter radiation fan for a long time, and waste very much electric power.
For the problems referred to above, a kind of controlling method of novel radiation fan is provided, to avoid the soft starter radiation fan, in running state, be the problem that prior art need to solve always.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of soft starter radiation fan, to avoid the soft starter radiation fan always in running state.
For solving the problems of the technologies described above, the technical solution of the utility model is, a kind of soft starter radiation fan, it is characterized in that: the controlling method of described radiation fan is conducting and the cut-off that the soft output of the microprocessor by starter low and high level is controlled triode Q6, thereby the adhesive of control relay K3 and release, the pick-up contact access socket JX4 of relay K 3, the mainboard of two pin access soft starters of socket JX4 carries out power taking, thereby works by the software control radiator.
The model of described microprocessor is LPC2136.
38 pin of described triode Q6 access microprocessor.
The N end of the public termination soft starter motherboard power supply of described relay K 3, the normal battle received the 1st pin of socket JX4, and the 2nd pin of socket JX4 is received the L end of soft starter motherboard power supply.
A kind of soft starter radiation fan, owing to adopting the foregoing circuit structure, this controlling method has the following advantages: 1, do not need additional power source, by the power taking of soft starter mainboard; 2, not only played to the thermolysis of thyristor simultaneously but also avoided traditional soft starter radiation fan always in running state; 3, reduce the probability that radiation fan damages, save electric power.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
The main circuit diagram that Fig. 1 is a kind of soft starter radiation fan of the utility model;
The relay K 3 control circuit figure that Fig. 2 is a kind of soft starter radiation fan of the utility model;
The socket JX4 circuit diagram that Fig. 3 is a kind of soft starter radiation fan of the utility model;
The work-based logic block diagram that Fig. 4 is a kind of soft starter radiation fan of the utility model;
The software flow pattern that Fig. 5 is a kind of soft starter radiation fan of the utility model.
Embodiment
As Figure 1-3, the microprocessor output low and high level that the utility model is soft starter is controlled respectively conducting and the cut-off of triode Q6, thereby the adhesive of control relay K3 and release, the pick-up contact access socket JX4 of relay K 3, the mainboard of two pin access soft starters of socket JX4 carries out power taking, thereby works by the software control radiator.
As shown in Figure 4, on the utility model soft starter display floater, the starting button is to activating signal of microprocessor, and soft starter brings into operation, and radiation fan is started working simultaneously.After operation a period of time, soft starter is in bypass condition, and now radiation fan will continue to move after a period of time out of service.
The model of microprocessor is LPC2136, by control relay disconnect, closure controls the starting of soft starter radiation fan and stops.Relay K 3 is to be controlled by corresponding triode Q6.Triode Q6 directly is connected with the 38th pin (P0.12) of microprocessor by resistance.Get final product the action of control relay by the low and high level of controlling this pin.
Relay K 3 is used for controlling the operation of radiation fan and stopping, and by socket JX4, to the soft starter radiation fan, powers.The N end of the public termination soft starter motherboard power supply of relay K 3, the normal battle received the 1st pin of socket JX4, and the 2nd pin of socket JX4 is received the L end of soft starter motherboard power supply.
Software section of the present utility model as shown in Figure 5, has judged whether activating signal after the soft starter mainboard powers on, when activating signal having been detected, and relay K 3, K4 output, soft starter and radiation fan bring into operation; After soft starter bypass a period of time, relay K 3 outputs, radiation fan is out of service.
When relay K 3 control pin OUT2 have high level output, corresponding triode Q6 conducting, the normal closure of making war of relay K 3, OUT2-A and OUT2-C conducting, now socket JX4 the 1st pin and the conducting of soft starter motherboard power supply N terminal, now soft starter radiation fan energising is started working.When relay K 3 is controlled pin OUT2 output low level, relay K 3 is normally closed closed, and normal the battle disconnects, and OUT2-A and OUT2-C disconnect, and now soft starter radiation fan outage quits work.
Stop signal detected in soft starter operation and by-pass procedure, soft starter is out of service, if now radiation fan is also in running order, and relay K 3 outputs, radiation fan is out of service.
The utility model does not need additional power source, by the power taking of soft starter mainboard; Utilize a road Control radiation fan starting and stop; And after the soft starter starting, radiation fan brings into operation, and after bypass a period of time, radiation fan quits work, both played the thermolysis to thyristor, avoided again traditional soft starter radiation fan always in running state, reduced the probability that radiation fan damages, saved electric power simultaneously.
The above is exemplarily described the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as the various improvement that adopted technical solutions of the utility model to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
