Mount Everest on Electricity [Today's Talk]: The difference between "heating" and "overheating"; the three stages of "Electrical Contact Overheating":
1. To clarify the boundary between "overheating" and "heating":
1. The resistance of the current flowing through the conductor has temperature, and it is normal for electrical equipment, conductors and wires to "heat" (the basic concept of Ohm's law)! "Nobel" got into the tip of the horns and imagined "superconducting" materials with no resistance and no heat. But I don't know that the man-made calamity of the electrical disaster is not caused by the "heating" of the conductor!
(If the outside temperature is lowered to a few hundred degrees below zero, there is no heat, no resistance, no temperature "superconductivity"! The earth is not frozen?)
2. The temperature of electrical contacts and joints exceeds (higher) the temperature of its conductors and wires, which is called "electrical contact overheating".
3. Conductors and wires exceed the rated current, and electrical equipment exceeds the capacity and overheat. This is "overload" or "overload". This is another matter with our "electric contact overheating"!
Electrical faults, accidents, and disasters generally occur in conductors, wires, and electrical equipment, but they have not exceeded the "maximum temperature rise" or reached the "overheating" level! Man-made disasters caused by "overheating of electrical contacts and connectors".
2. Three different stages of "Electrical Contact Overheating":
Electrical contacts are overheated: it is not equipment, conductors and wires are "heating", nor is equipment, conductors and wires are "overheating"!
1. Initial stage: The temperature at the electrical contacts and joints exceeds (higher) the temperature of the conductors and wires, and the electrical energy has been converted into heat energy, resulting in increased loss. The "line loss" is counted, and it is accustomed to it due to a wrong concept. (Single talk about energy saving)
2. Discovery stage: The temperature of the electrical contacts rises again, and the insulation at the joints is burned out and red (with greater loss). It is discovered before accidents or disasters have occurred, and the power is cut off and repaired in time!
In recent years, the use of artificial intelligence "high-tech" monitoring, early detection of faults, early power outages and repairs, although effective in reducing accidents, it is still a symptom, not a cure, and there is no way!
3. Disaster stage: electrical contacts are overheated, the joints are red and burned, the circuit is short-circuited, the power supply is interrupted, causing air disasters, electrical fires, bus "self-ignition", etc., various electrical disasters! (Electric power public safety, life is the top priority for people's livelihood)
To sum up: In the power system, short circuits of electrical circuits, causing electrical faults, accidents, and disasters, are generally located at electrical contacts and joints! As long as the temperature of the electrical contacts and joints does not exceed (below) the temperature of its conductors and wires by more than 5% of the "not hot electrical contacts"! The man-made calamity caused by the "electrical contact overheating" circuit short-circuit, can't be solved! Why go against the basic principles of Ohm's law and go to great lengths to get a "superconducting" material with no resistance and no temperature? !
Subvert the traditional wrong concept of "electrical contact overheating", correct the technical method of curing the symptoms but not the root cause, consolidate the foundation of electric power public safety, and take the new path of "electrical contact is not hot"! Everyone has the same electricity and uses electrical power! You and me (public servants) have peace of mind! !
There are hidden dangers in global power safety, and it is wrong to avoid electrical disasters! It's even more a crime to avoid doctors! The man-made disasters of various electrical disasters must be solved from the source of electricity, remember! Remember! !
Note: Distinguish the boundary between "occurrence" and "overheating"; understand the heating and overheating of electrical equipment, conductors and wires; and the difference between them and "overheating of electrical contacts", you will soon become an expert! http://www.scrydq.com;

www.China Renyi Electric. Website; platform, build the summit of Mount Everest, declare war and challenge the global electrical disasters, sincerely invite politicians, academicians, experts, and people of insight from all over the world to fight and attack!


119 Safety and firefighting must be done practically. "Superconductivity" cannot solve man-made disasters such as electrical fires!

Pay special attention to the power safety revolution forum, and Mount Everest discusses electricity-to solve the mystery of a century of electrical disasters in the world of man-made disasters! Solve and eradicate the global ...

Special attention should be paid to national power safety in summer
