Protection grounding method for the motor of the reaction kettle
Thread Content
The reaction tank is very tall, which results in a long grounding wire for the motor enclosure; this arrangement is not standard and can lead to damage. Is there any better way? I would appreciate some guidance. Thank you!
You can use that steel piece over there and run it down along the base
Ahah, this marine engineer usually achieves grounding for such equipment by running it together with power cables or control cables! Generally, for equipment such as mixers that are installed vertically, the elevation of the drive motor is higher than that of the equipment itself. The power cables and control cables of the motor are laid using cable trays along the main pathways; near the equipment, these cables are protected by conduit. In this case, the motor’s casing can be grounded by running it together with the power cables in conduits, and then connecting it to the corresponding main grounding network on the floor where the motor is located. This approach helps to ensure proper protection of the grounding wires as well as to maintain an orderly appearance of the cables in place Additionally, it is also possible to use the main grounding busbar on the corresponding floor and run wires separately through conduit pipes (the brackets can be welded to the equipment foundation or shared with the pipeline bracket foundation), leading them to the motor foundation grounding point.
1. Locate a spot near the wall where flat steel can be laid; run a flat steel bar from the main grounding conductor along the wall to the nearest point to the motor, and connect it using a grounding wire. 2. Use tray brackets and similar items to lay the wire conduits, and run the grounding wires through these conduits to a location where they can be connected to the flat steel bars.
