August to September period, Wenzhou Low Voltage Electrical Apparatus Laboratory successfully completed the third phase of the life of 13 test port control circuit debugging work, together with the short circuit test before the completion of each port debugging, the laboratory's core short-circuit system and electrical life System control circuit has been fully debugged. Before May, the laboratory had verified the short-circuit ports by the low-voltage method and evaluated the impedance and acquisition system of the circuit. The results showed that the system met the design requirements under low-voltage conditions.
At this point, Wenzhou Low Voltage Electrical Laboratory Phase III project already has a full voltage power-on test conditions. (Ruian Office Wang Jianxin)

During the maintenance of the mixing station, the main power supply must be cut off, the door of the distribution cabinet must be locked, and the key should be kept by the electrician.Power cutting and transmission must be operated by electrician.When starting the belt conveyor, mixing host, and other motors, it is necessary to observe whether there are people or other sundry things on the motor, in order to prevent injury or damage to the equipment when starting. When cleaning, it is strictly prohibited to flush the electric motor, electrical switch, solenoid valve and other electrical appliances with water to prevent electric shock and damage to electrical equipment.When the mixer is working, it is forbidden to stand in the discharging area.Non-operators are forbidden to enter the control room, smoking and doing things unrelated to the operation are prohibited.There is no operator in the operating room. Power must be cut off and doors and Windows must be locked before leaving.
