Is The Role Of Surge Protector Really So Important? You Will Know After Reading This
Why don't we get electric shocks indoors during thunderstorms? Because equipotential connection plays a huge role! Equipotential connection is to make all objects that may conduct electricity at the same potential without generating potential difference. Only when there is a potential difference can current be generated. If we are in an equipotential state, we will naturally not get electric shock. So what is the relationship between surge protectors and equipotential?
Building Lightning Protection Design Code GB50057-2010 defines equipotential connection as: connecting separate devices and conductive objects with equipotential connection conductors or surge protection device to reduce the potential difference generated between them by lightning current. Simply put, in the same building, the total equipotential connection in grounding protection means that all metal conductive objects must be connected to the same potential (usually refers to grounding), and all grounding devices must also be connected to the same ground to maintain the same potential.
surge protective device is equivalent to an intelligent equipotential connector, which connects the charged phase line and the ground line. Under normal working conditions, it is equivalent to a huge resistor, which generally does not affect the normal operation of electrical equipment. However, once a lightning surge invades the line, it will quickly conduct and discharge the lightning current to the grounding device, while limiting the lightning voltage within a safe range, so that no potential difference is generated inside the building.
Therefore, under the action of the surge protector, there will be no equal potential difference indoors, and the interior will always maintain an equal potential state. Even if there is thunder outside, we can work safely indoors!
In summary, it is because of the role of the surge protector that our lives can be free from lightning intrusion. So many people call surge protectors lightning arresters! Whenever the critical moment, the surge protector will stand up and discharge high current and high voltage to the ground to protect our lives and property!
