Power distribution requirements of oil cooled electric roller conveyor

Low voltage AC motors commonly used for belt conveyors shall be equipped with overcurrent protection and grounding devices for common fault maintenance, and integrated processing chip integrated protectors such as overvoltage protection, phase failure protection and under working voltage maintenance shall be set respectively according to the details. The freight logistics data signal in the production line of belt conveyor and the signal detection equipment such as deviation, deviation, vertical tear, ribbon, overspeed and material blockage of conveyor belt shall be determined by the production process standard, and the power distribution design shall meet its provisions. Wutong tree electric roller can be customized according to user needs.

The main circuit and control circuit shall be powered on and tripped at the same time. Otherwise, when the switching power supply of the control circuit is powered, and the power supply of the main circuit trips and repairs and sends power, it will cause self start, which is easy to produce safety accidents. Therefore, there should be chain operation. The distribution switching power supply of electrical equipment of the same belt conveyor should come from the same bus duct. Several motors on the belt conveyor route are started, and the starting working voltage is not less than 80% - 90% of its rated current, which does not endanger the operation of oil-cooled electric roller and other power consumption facilities. When several sets cannot be started at the same time to meet the needs, they shall be started in several times. For example, the starting of the motor unit of the middle friction belt conveyor is the same as the ignition sequence of the engine cylinder.

The procedure flow of starting and stopping the conveyor is defined by the processing process standard. In operation, when parking in case of failure of all chain franchise equipment, priority shall be given to the belt conveyor in the feeding direction according to the reverse operation direction. The conveyor of belt conveyor shall be able to join in chain, complete the machine side operation, and carry out single machine adjustment. The low-voltage protection device should select the under working voltage circuit breaker of the low-voltage circuit breaker or the magnet coil of the AC contactor, and its control circuit should select the main circuit of the motor for power distribution. The motor and operating household appliances should use the same set of isolator.
