The oil in OCBs serves two purposes. It insulates between the phases and between the phases and the ground and it provides the medium for the extinguishing of the arc.When electric arc is drawn under oil, the arc vaporizes the oil and creates a large bubble that surrounds the arc. The gas inside the bubble is around 80% hydrogen, which impairs ionization. The decomposition of oil into gas requires energy that comes from the heat generated by the arc. The oil surrounding the bubble conducts the heat away from the arc and ....etc

Oil Circuit Breaker
a high-voltage AC electrical switch whose main contacts are located in a space filled with mineral (transformer) oil. Upon interruption of the electric circuit, an electric arc forms between the contacts of the circuit breaker. Because of the high temperature of the arc the oil is evaporated rapidly and oil vapors are partially decomposed, liberating ethylene, methane, and other gases. A gas bubble is formed in the arcing zone; the pressure in the bubble may be as high as several dozen meganewtons per sq m. The arc is then ....etc

minimum quantity lubricant ppt

Minimum Quantity Lubrication (MQL) goes by many names. It has been referred to as Minimal Quantity Lubrication , Near-Dry Machining or NDM , Micro-Lubrication or Microlubrification , Micro-Dosing , and sometimes even gets incorrectly referred to as mist coolant. Minimum Quantity Lubrication (MQL) is an alternative to the use of traditional metal working fluids (MWFs) in machining. You may have heard MQL referred to as Near-Dry Machining (NDM), Micro-Lubrification or Micro-lubrication , Micro- ....etc

Touch screen operated industrial oil dispensing system (OIL SCADA)
The project aims in designing a system which is capable of dispensing required
amount of oil given by the user through touch screen. This system also provides the
security of accessing through password enabled feature. Liquid dispensing systems are
quite commonly found in our daily life in different places like offices, Bus stands,
Railway stations, Petrol pumps. Here we are going to present modern era liquid
dispensing system which is meant to be operated with touch screen inte ....etc

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overcurrent or overload or short circuit. Its basic function is to interrupt current flow after protective relays detect a fault. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear de ....etc
