High voltage electrical insulation, discharge control, and protection technology for electrical equipment.
Keywords: High voltage insulation, high current interruption, discharge suppression, electrical insulation in general, high voltage technology in a vacuum, fuse technology.
High voltage (generally electrical equipment over 600V) is used in various places, starting from power transmission and distribution. This is because it allows for efficient use (transport) of electricity and makes it easier to generate high electric fields. When attempting to use electricity at high voltage, unexpected breakdowns in electrical insulation (preventing electricity from flowing) can occur, leading to discharges (similar to small lightning) that can cause power outages or damage to equipment. It is important to prevent such occurrences, and to ensure that electricity can be used safely and securely, proper electrical insulation must be maintained. If electrical insulation is completely compromised and a large current flows, it can lead to catastrophic accidents such as fires or explosions, as well as equipment failures. Even if such incidents occur, it is also crucial to have protective devices that can immediately cut off the large current (referred to as disconnection in electrical terms) to minimize accidents. In our laboratory, we conduct research on electrical insulation using "vacuum," which has excellent insulating properties. We are also researching fuses to protect equipment when a large current flows due to electrical accidents.
