Vacuum interrupter, also known as vacuum switch tube, is the core component of the medium and high voltage power switch, its main role is that, through the excellent insulation of the vacuum inside the tube to make the medium and high voltage circuit cut off the power supply can quickly extinguish the arc and inhibit the current, to avoid accidents and accidents, mainly used in power transmission and distribution control systems, but also used in metallurgy, mining, petroleum, chemical, railway, broadcasting, communications, industrial high frequency heating and other power distribution system. It has the characteristics of energy saving, material saving, fire prevention, explosion-proof, small volume, long life, low maintenance cost, reliable operation and no pollution. The vacuum interrupter room is divided into interrupter room for circuit breaker and interrupter room for load switch. The interrupter room for circuit breaker is mainly used for substation and grid facilities in the electric power sector, and the interrupter room for load switch is mainly used for end users of the grid.
The outer casing of the vacuum interrupter is made of insulating material (ceramic or glass), and the two ends are sealed with a metal cover to form a closed container. There are a pair of contacts inside, the static contact is fixed on the static conductive rod, and the movable contact is fixed. On the moving rod. Since the bellows is sealed between the movable conductive rod and the metal cover, the movable conductive rod can move in the axial direction to drive the contacts to complete the splitting and closing action.
The bellows of the vacuum interrupter chamber is mainly responsible for ensuring the movement of the dynamic electrode within a certain range and maintaining a high vacuum for a long time, as well as ensuring that the vacuum interrupter chamber has a high mechanical life.
The bellows of the vacuum interrupter is a thin-walled component made of stainless steel with a thickness of 0.1 to 0.2 mm. In the process of dividing and closing the vacuum switch, the bellows of the interrupter chamber is subjected to expansion and contraction, and the bellows section is subjected to variable stress, so the life of the bellows should be determined according to the repeated expansion and contraction and the use of pressure.
The fatigue life of the bellows is related to the working conditions of the heated temperature. After the vacuum interrupter chamber has broken up a large short-circuit current, the residual heat of the conductive rod is transferred to the bellows, causing the temperature of the bellows to rise, and when the temperature rise reaches a certain level, this affects the fatigue strength of the bellows.
