PSCDM024DCBAN A5E0024837106
PSCDM024DCBAN A5E0024837106因某種原因電源電壓突然消失，電動(dòng)機(jī)都會停轉(zhuǎn)。一旦電壓恢復(fù)正常，如果電動(dòng)機(jī)自行起動(dòng)，往往會造成設(shè)備損壞或人身事故，也會因許多設(shè)備同時(shí)起動(dòng)而造成對供電網(wǎng)絡(luò)的過大沖擊。因此，在電網(wǎng)電壓消失時(shí)，要立即切斷電源，實(shí)現(xiàn)零電壓保護(hù)。
PSCDM024DCBAN A5E0024837106電源電壓過分降低，會引起電動(dòng)機(jī)轉(zhuǎn)速下降甚至停轉(zhuǎn)；在負(fù)載轉(zhuǎn)距不變的情況下，電動(dòng)機(jī)電流增大，造成繞組過熱而損壞；電壓過低還會引起一些電器釋放，造成控制失常。因此，當(dāng)電源電壓降低允許值以下時(shí)，需要切斷電源，實(shí)現(xiàn)欠電壓保護(hù)。起保停電路本身具有失壓保護(hù)和欠壓保護(hù)的功能。當(dāng)電源失壓或嚴(yán)重欠壓時(shí)，接觸器的銜鐵自行釋放，電動(dòng)機(jī)停止運(yùn)轉(zhuǎn)。當(dāng)電壓恢復(fù)正常時(shí)，接觸器線圈也不會自行通電，只有在操作人員再次按下起動(dòng)按鈕時(shí)，電動(dòng)機(jī)才會起動(dòng)。有的電路要求有更好的零壓和欠壓保護(hù)，還采用專門的欠壓繼電器或欠電壓保護(hù)電路。

For some reason, the motor will stop when the power supply voltage suddenly disappears. Once the voltage returns to normal, if the motor starts by itself, it will often cause equipment damage or personal accidents, and it will also cause excessive impact on the power supply network because many equipment start at the same time. Therefore, when the grid voltage disappears, the power supply should be cut off immediaby to realize zero voltage protection.
If the power supply voltage is excessively reduced, the motor speed will drop or even stop; When the load torque is constant, the motor current increases, resulting in winding overheating and damage; Low voltage will also cause some electrical appliances to release, resulting in abnormal control. Therefore, when the power supply voltage drops below the allowable value, it is necessary to cut off the power supply to realize undervoltage protection.
The start stop circuit itself has the functions of voltage loss protection and undervoltage protection. In case of PSCDM024DCBAN A5E0024837106 power loss or serious undervoltage, the armature of the contactor will release automatically and the motor will stop running. When the voltage returns to normal, the contactor coil will not be energized by itself. The motor will start only when the operator presses the start button again. Some circuits require better zero voltage and undervoltage protection, and special undervoltage relay or undervoltage protection circuit is also used.
