Question 2: What is the electrical interlock As shown in the figure below, where KM1 and KM2 for the electrical interlock, when SB1 is pressed at the same time as SB2, SB2 will not work, so as to prevent the main circuit from short-circuiting.
Question 3: What is the principle of mechanical interlocking and electrical interlocking? Where is the difference? Electrical interlocking is to realize interlocking through the relay, contactor contacts, such as motor positive, positive contactor contacts cut off the electrical path of the reverse button and reverse contactor.
Mechanical interlocking is to realize interlocking through mechanical parts, such as two switches can not be closed at the same time, you can use mechanical leverage, so that when one switch is closed, the other switch is mechanically stuck can not be closed.
Electrical interlocking is easier to realize, flexible and simple, interlocking the two devices can be installed in different locations touch, but less reliable.
Mechanical interlocking is highly reliable, but more complex, sometimes even impossible to realize. Usually the two interlocking devices should be installed in close proximity to each other.
Question 4: What types of mechanical interlock contactors are available? Basically all contactors are mechanically interlocked unless they are not required. Now there are many contactors can be hooked up to the auxiliary contacts. The use of these auxiliary contacts can do interlocking.
Question 5: Electrician practice circuit diagrams, which are electrical interlocks, which are mechanical interlocks The normally closed point of the contactor and the normally closed point of the button into another circuit is an electrical interlock
The normally open and normally closed point of the button linkage is a mechanical interlock
Question 6: Why is it important to use electrical interlocks when mechanical interlocks have been adopted for control circuits? In short words, safety!
This is my understanding, huh
Double protection chant ~
Question 7: What is the mechanical interlock. How to draw a simple illustration of a mechanical interlock 20 points A mechanical interlock is a mechanical method of interlocking several related wow components with each other. As shown in the figure below, two handles, A and B, have a round pin in the center, and only when one of them is turned so that the plane faces the pin can the other be turned.
Mechanical interlocks are widely used in some equipment, such as: the lathe's tool walk and screw feed is, due to interlocking, thus ensuring that both of them are allowed to have only one in action.
Question 8: Mechanical interlocking structure 30 points, please refer to the fan speed of the piano Jian switch
Question 9: Mechanical interlocking structure of the door 50 points between the ab door to do a linkage limit mechanism on the line, the A door open, the limit mechanism card such as the door of the B door in the unlocking mechanism, do not allow him to rotate, and the reverse as on the line!
Question 10: What is the interlock in the electrical control? How to realize? 10 points electrical control interlock is mainly to ensure the safe operation of electrical appliances and set up. It is mainly by the two electrical components to control each other and the formation of interlocking. There are three main means to realize it, one is electrical interlocking. The second is mechanical interlocking, the third is electrical mechanical linkage interlocking. Electrical interlocking is; the two relays will be normally closed contacts into the coil of another relay control circuit. In this way, one relay is electrically actuated, and it is not possible to form a closed circuit on the coil of the other relay. But also can use mechanical linkage to realize this action. Third, electrical and mechanical interlocking. Such as high-voltage cabinets within the dingdian, not open the switch, isolation switch can not be pulled, the above can not be pulled open to close the grounding knife gate, pull the grounding knife gate, can not open the high-voltage cabinet door, can not be switched on the inspection and so on.
