Does the low-voltage standby automatic switch need mechanical interlocking?

Jack-up braking of low-voltage equipment requires mechanical interlocking, which is to ensure the safety of operators and equipment. The mechanical interlock should interlock the lever device and the control circuit to form a perfect electrical protection system to prevent the dislocation of the high-voltage operating lever installed on the low-voltage electrical equipment and the low-voltage operating principle. This can avoid electrical accidents caused by abnormal operation and ensure the normal and safe operation of the equipment. Therefore, attention should be paid to the selection and setting of mechanical interlocking in the design to improve the safety, stability and reliability of equipment operation.
