1. The rated operating time of the upper and lower leakage protectors is as specified in the "Procedures for Installation and Operation of Leakage Protectors", the step is 0.2s. The rated operating time of the leakage protector for end protection is fast, and the operating time is less than 0.1 s. Main line or minute The rated action time of the leakage protection device for the secondary protection of the branch line is increased by 0.2 s. The third-stage protection increases the delay by 0.4 s.
2. It is also possible to use the anti-time delay characteristic of the leakage protector. The second stage is extended by 0.1 s from the first stage, and the third stage is increased by 0.2 s.
3. If the leakage protector selected at the construction site is of anti-time limit type, the IEC does not have corresponding regulations, and the operation time can be matched with reference to the Japanese standard. When the leakage current is IΔn (rated leakage current), 1s ≥ action time t>0.2 s; when the leakage current is 1.4I Δn, 0.5s ≥ action time t>0.1 s; when the leakage current is 4.4IΔn, action time t<0.05s.
Tobacco control has been a common global concern, while the traditional tobacco industry gradually, new tobacco has become the new strategic layout of tobacco giants. In this context, the emergence of e-cigarettes has further led to the replacement of traditional tobacco. At present, there are already a thousand different types of e-cigarettes, which have undergone several stages of development. The e-cigarette we are introducing today is the CBD pod systewm, a new type of e-cigarette. In this article we will combine the characteristics of the CBD with a brief analysis of it.
·Anti-anxiety
According to scientific studies,CBD can help depressed patients reduce their anxiety. The use of CBD can help maintain endogenous cannabinoids at a reasonable level, making the patient feel good and happy physically, and without any dependence.
·Anti-ageing
CBD is very powerful in anti-ageing. As a non-psychoactive component of the cannabis plant CBD inhibits the glutamate toxic response of cortical neurons and suppresses excessive oxidative stress, helping the body to achieve anti-ageing effects.
·Anti-inflammatory
CBD reduces the free radicals that cause neurodegenerative diseases and reduces swelling through its anti-inflammatory effects. In addition, CBD stimulates appetite and relieves pain.
