In today's power system, keywords such as Rittal cabinet,Rittal Air Conditioner and Rittal busbar have become industry hot spots. In this article, we will discuss the importance of ground zero and the ground zero solutions offered by Rittal, aiming to provide readers with in-depth understanding and useful information about the keywords.
1. The role and importance of the neutral ground wire
In power systems, the neutral ground wire plays a vital role. It not only ensures the normal operation of electrical equipment, but is also directly related to the safety and reliability of the entire system. But what exactly is ground zero?
According to the definition of the national standard GB/T 7251.1-2023, the accurate names of the neutral ground wire are "protective conductor (PE)" and "neutral conductor (N)". A protective conductor is a conductor provided for safety purposes and is used to protect against electric shock. The neutral conductor is a conductor that is connected to the neutral point in electricity and can participate in the distribution of electrical energy.
2. National standards’ requirements for ground zero emissions
The national standard GB/T 7251.1-2023 clearly stipulates the requirements for ground zero emissions. Specifically, when the cross-sectional area of the neutral conductor in the circuit is ≤16mm², the cross-sectional area of the neutral conductor should be the same as the line conductor. When the cross-sectional area is greater than 16mm², the cross-sectional area of the neutral conductor shall not be less than half of the cross-sectional area of the line conductor, and the minimum shall be 16mm². In addition, the standard also clarifies the specification requirements for copper protective conductors.
3. Rittal zero ground discharge solution
In order to meet different needs, Rittal provides N/PE copper bus components in various specifications and can provide a variety of standard solutions. Here are the four main features of Rittal ground zero solutions:
Standardized, prefabricated terminals, flat mounting: Rittal uses standard ground rail solutions, which simplifies the installation process and provides a simple and straightforward solution that customers can use directly.
