Who can talk about the details of the use of contactors on the elevator, I have come into contact with some of the circuit can see a little bit to understand, but in fact to Mongolia, who can elaborate on what, the best example, such as Some of the contacts of the contactor, interlock, the purpose is to see the intestinal 礌 spotting alone do sweepers of the contactor I can understand which line is the coil, which line is the main contact, which is Interlocking, and some other what, depressed do not know even asked do not know how to ask, who can elaborate under the big brother. More
Electrical schematic diagram should be the number of lines or the number of the kind of look at the kind of look to know which is the coil, which is interlocked. Generally the main contact line must be on the main circuit diagram, the other should be in the control circuit.
This is not a good way to say. Specifically you can look at your circuit diagram, combined with the actual circuit. In addition, the label on the circuit diagram corresponds to the label of the component in the actual circuit. Interlocking point as long as the principle and role of interlocking, you can understand
The upper side of the coil is marked A1 and A2 is the two points of the coil. (NC) Most of the points are often used to open the signal point, the main contactor you must understand, like the door lock contactor, emergency stop contactor, brake contactor, In addition to the coil point, normally open normally closed are part of the detection circuit, to a part of the signal, the process is to monitor the elevator power phase sequence, the correct after the main power contactor pull, emergency stop loop, emergency stop contact (110V, 36V), often open point to the motherboard signal, the inverter signal, the operation of the contactor signal, the door is closed, then the door contactor pull, and then the door line, elevator, inside the security line (110V, 36V) (110V, 36V), often open the closed point to the motherboard signal, the system signal, run the contactor signal, run the contactor coil is given by the emergency stop contactor signal and door lock contact The signal is given in series, the first two contactors closed, then run the contactor to meet the conditions closed, the coil point also need to give the motherboard control line running signal, and finally the brake contactor pull, feedback a holding point , This is mostly long closed Intestine spotted spotted posture. You better or more to observe its run-time contact closure of the order, no more difficult to see a few times to see clearly, there is more simple drawings, it is best not to see the drawings, easy to Mongolia, on their own To think, and then go to the drawings contrast, see do not need to understand later, remember solid. And then tell you a study of the ruthless strokes · ordinary people I do not tell him ~ ~ ~ ~ Oh turn off the elevator power, the contact with things stuffed, so that they pull, you use the table which point and which point, after their own Draw a simple circuit diagram, then disconnect the amount. Technology this thing is not who taught, are stolen ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
