A vacuum circuit breaker is a high-voltage switchgear used in power systems. Its main function is to quickly cut off the circuit when a fault occurs. Its working principle is to use the characteristics of the arc in a vacuum environment to achieve disconnection and closing. Specifically, the main components of a vacuum circuit breaker include a vacuum chamber, a contact system, an operating mechanism, etc.
Oil circuit breaker is a common high-voltage electrical equipment, mainly used to protect and control circuits in power systems. Its working principle is based on the insulation and cooling properties of oil, and uses bubbles in the oil to extinguish arcs.
A high-voltage circuit breaker is an electrical device used in a high-voltage system. Its main function is to protect power equipment and circuits from short circuits, overloads and other faults.
An electric arc is a conductive phenomenon formed by the interaction of free electrons and ions in a gas or air under high voltage. When current passes through a gas, the electric field ionizes the atoms or molecules in the gas, generating a large number of free electrons, thus forming an electric arc. Electric arcs are usually bright and high in temperature, which can reach thousands of degrees Celsius. They are widely used in welding, cutting and various electrical equipment.
