oil-break switch的意思|示意

'

Oil-break switch refers to a type of switch that uses oil as a means of insulation and extinction of the arc generated when breaking the circuit. It is mainly used for high voltage power systems and provides reliable protection against short circuits and overloads.

The oil-break switch is composed of three main parts: the housing, the insulating oil, and the contacts. The housing is made of metal and acts as a container for the oil and contacts. The insulating oil is used to maintain the insulation between the contacts and to extinguish the arc generated when the switch is opened. The contacts are made of copper, silver, or another conductive metal and serve to open and close the switch.

The operation of the oil-break switch is based on the movement of the contacts. When the switch is closed, the contact area is completely immersed in the insulating oil, which prevents electrical breakdown. When the switch is opened, an arc is generated due to the interruption of the current. The insulating oil is then used to extinguish the arc, which prevents the current from continuing to flow.

In summary, the oil-break switch is an important component of high-voltage power systems. Its use of oil as a means of insulation and extinction of the arc allows it to provide reliable protection against short circuits and overloads.
