After purchasing the sewage treatment equipment, it is not said that it can be opened with just one click, but it needs to go through a series of processes such as installation and testing before operation. Of course, there is also the grounding step. How do we operate here?

Production, manufacturing, and installation of grounding system software for sewage treatment equipment. During the mutual grounding operation between the system software and the intermediate grounding system software, the grounding resistor should be less than 1 ohm, and the cable bridge and metal material maintenance tube should be used as the grounding wire. The various non electrochemical plastic casings of integrated buried sewage treatment equipment should be reliably grounded.

The grounding power circuit is connected to the first grounding component and the second grounding component on both sides of the module. The first grounding component is connected between the input terminal and the grounding terminal of the module, and the second grounding component is connected between the output terminal and the grounding terminal of the module.

Connection of grounding wire: The length of welding during connection should not be less than twice the total width of galvanized flat steel. The welding point should be sturdy and round, and necessary anti-corrosion measures should be taken. The connection between the grounding wire and the machine equipment can be connected by screws or welding. When connecting with screws, anti loosening screw caps or nuts should be installed.

The machine equipment adopts secondary lightning protection maintenance, and the vast majority of the lightning current is released based on the first grounding component at the module input end; The module output end is equipped with a second grounding component to reduce the residual voltage entering the load, which is beneficial for avoiding lightning strikes on the load, improving its application safety factor, and increasing its service life.

All electrical equipment and metal structures in the power plant of sewage treatment equipment are required to be grounded reliably, and the grounding resistor is required to be less than 1 ohm. And it is stipulated that the power device and computer software complete the total equipotential connection.

The shielded twisted pair cable is grounded at two points, which limits the size of the ground current or influence, and can prevent the risk of damage to the shielding layer of the shielded twisted pair cable when the ground current or influence is too large. The copper core cables with shielded twisted pair cables are designed with a shielding layer for copper core cables, which is beneficial for suppressing electromagnetic wave radiation, electrostatic induction coupling, and magnetic effects caused by current in the middle of the copper core cables; In addition, a cable shielding layer has been designed to suppress external interference signals.
