According to the report of the NHK website of Japan on December 30th, solar energy and other renewable energy sources are becoming more and more popular. Japan's various material companies have begun to develop light and thin, thin-film solar cells that can be installed on room walls and windows.
The principle of the new type of solar cell that has not yet been developed is to coat the film with a special compound that can generate electricity. Even if the battery is bent, it can be used, so it can be installed on the walls and windows of a room.
It was previously predicted that the low-cost mass production of this battery would be very difficult, and it would take a certain amount of time to popularize the battery. However, in this case, the large-scale chemical company "Jizui Chemical Industry" actually developed a technology that can realize mass production. The compounds that can be generated need to be attached to the thin film at a high temperature of 500 degrees. Through R&D of this technology, the process can be carried out smoothly under normal temperature conditions, which greatly improves the production efficiency.
Kosuke Kosaka, director of the Sekisui Chemical Industry Development Promotion Center, said: "This new type of solar cell can be installed in various places such as pillars and walls. It can easily generate electricity, and we are welcoming us to travel with electricity. era".
Arcing horns are protective devices that are constructed in the form of projections in the conducting materials on both sides of an insulator.
Arcing horns are fitted in pairs. Thus in transmission lines they are found on the conducting line and the transmission tower across the insulators. In transmission lines, in the event of a lightning strike on the tower, the tower potential rises to dangerous levels and can result in flashovers across the insulators causing their failure. Arcing horns prevent this by conducting the arc across the air gap across them.
Arcing horns function by passing the high voltage across the insulator using air as a conductive medium. The small gap between the horns ensures that the air between them breaks down resulting in a flashover and conducts the voltage surge rather than cause damage to the insulator.The horns are constructed in pair so that one horn is on the line side and the other is on the ground side.
Arcing Horns are also used along with air insulated switchgear equipment. Air insulated switchgear are vulnerable to damage due to arcing. Arcing horns serve to divert the arc towards themselves thus protecting the switching equipment. The arcing horns serve to move the arc away from the bushings or the insulators.
