Description

Common substrate for lightning protection grounding, protection grounding and anti-static grounding

Technical Field

The utility model relates to the technical field of grounding wire bases, in particular to a shared substrate for lightning protection grounding, protection grounding and anti-static grounding.

Background

The lightning protection ground connection of mill, overall structure lightning protection (main building lightning protection), earthing pole, earthing band are beaten to main basis, form a ground net, and ground resistance is less than 10 Europe. And then is connected with the main body of the steel bar or steel structure of the main workshop. The cement concrete roof is connected with a lightning strip or a lightning rod, the ground test point is reserved on the outer surface of the wall, and the steel structure is directly led to the roof by using galvanized flat iron. The power supply system grounding is divided into protection grounding and working point grounding, and the protection grounding is the grounding of the shell of the live equipment. The grounding of the working point refers to zero line grounding, the grounding net is the same as the lightning grounding mode, and the grounding resistance is less than 4 ohms. If the requirement is not met, a grounding electrode should be added, and if the condition is not good, an electrolyte should be added and/or the soil should be replaced.

The working ground and the protective ground are independently led out from the power distribution room, and the system can be combined into one. The working modes, such as the ground wire and the zero wire are separated, and can also be combined into one to be led to the electric system (or equipment). The grounding system must be repeatedly grounded. There is also a separate approach, TN-S system. Zero ground can no longer be a one.

An instrument grounding system or an anti-static grounding system. The system ground resistance is less than 1 ohm and is usually separated from the lightning protection ground.

The grounding bodies are usually respectively made into grounding bodies to form independent grounding nets to meet respective standard standards due to different resistance requirements, the grounding bodies are usually made into galvanized angle steel or steel pipes with the lengths of 3 and 2.5 meters, and are arranged in a row or in an angular shape according to a certain distance or in a straight line, if the grounding bodies meet places with poor geological conditions, the resistance cannot meet the requirements, resistance reducing agents need to be added, three groups of grounding nets need to be made, repeated construction is caused, and the effect is poor.
