2024年8月14日 · We can designate a principal quantum number, n, and a certain subshell by combining the value of n and the name of the subshell (which can be found using l). For example, 3p refers to the third principal quantum number (n=3) and the p subshell (l=1).

1p+n：性价比高，但需严格接线。 2p/4p：安全性高，适合关键位置。 3p/3p+n：专为三相系统设计。 核心原则：根据负载类型、安全需求和预算综合选择，切勿为省钱牺牲安全性！

2017年4月25日 · For electrons located in a 3p orbital, the principal quantum number is equal to. n = 3 → the third energy level. So, you know that you have n = 3. Next, find the value of the angular momentum quantum number, l, which gives you the subshell in which the electron is located.

3p+n由于少了一极，所以在断开线路时，只能断开3根火线，零线上下还是直通的。 在要求N线 必须 分断的场所，使用 4P 在要求N线 不能 分断的场所，使用 3P+N

2021年8月13日 · Schrödinger’s approach uses three quantum numbers (n, l, and ml) to specify any wavefunction. The quantum numbers provide information about the spatial distribution of an electron. Although n can be any positive integer, only certain values of l and ml are allowed for a given value of n.

要是确定需要断开中性线，而且中性线电流不会超过相线电流，从省钱的角度考虑，可以选 1p+n、3p+n；要是中性线电流有可能超过相线，比如受到谐波影响的时候，就得选 2p、4p。

Radial distribution curve gives an idea about the electron density at a radial distance from the nucleus. The value of 4πr 2 ψ 2 (radial probability density function) becomes zero at a nodal point, also known as a radial node. The number of radial nodes for an orbital = n- l -1. Where n = principal quantum number and l = azimuthal quantum number.

2023年3月22日 · First, we know that the principal quantum number (n) for all three orbitals is 3, as indicated by the number before the letter (s, p, or d). Next, we need to determine the azimuthal quantum number (l) for each orbital. For the 3s orbital, l = 0. This is because the s orbital has a spherical shape and only has one orientation in space.

3p空开是指断路器有三个极，他们都有故障跳动性能；3p+n其实有四个极，但是3极具有主跳性能，即这三极所接线在发生故障时都能正确迅速的跳开，而这个n不具有主动性，它只具有随跳性，即随着3p的动作而动作，否则它不会动作。

2017年10月23日 · 小型断路器1p、1p+n、2p到底有什么不同？ 答：对于微型断路器来说，1P+N、1P、2P一般都用来作为单相用电器的通断控制，但效果不同。 1P------单极断路器，具有热磁脱扣功能，仅控制火线（相线），模数18mm；
