Electrical installation is divided into high pressure and low pressure. The wiring of the high-voltage power supply and the wiring at the top beam cannot be made of ordinary wires, but the round steel with random matching should be used. The high-voltage line in the top beam must avoid electrical equipment such as electric heaters and temperature controllers. The distance should be greater than 300mm to prevent signal interference. Low voltage installation should also pay attention to the following points:
(1) The wiring of the rapping motor must pay attention to the positive and negative poles, and the motor cannot be reversed to avoid damage to the rapping system.
(2) The platinum resistance of the temperature measurement shall be installed on the base of the insulating porcelain casing in the inlet and outlet end beams, and shall not be mounted on the box beam.
(3) Check whether the signals such as the top beam temperature measuring platinum resistance, the zipper and the feeder switch, and the hopper level gauge are connected to the central control.
