ELEMENT FOR PRODUCING TRIGGERED ARC

摘要

An element (109) for producing a triggered arc is installed between two electrodes (103,104) to form a trigger circuit. Both end surfaces (110,111) of the element (109) respectively make electrical contact with both of the electrodes (103,104), and the element (109) is made of conductive material. The element (109) comprises a conductor (101) and an insulator (102). The conductor (101) makes electrical contact with both of the electrodes (103,104). A designated area of the conductor (101) forms an arc striking area (105), and both of the electrodes (103,104) compose an arc striking space (112) together with the arc striking area (105). The triggered arc is produced in the arc striking space (112) when an overvoltage is applied. The areas on the conductor (101) except the part making contact with the electrodes (103,104) and the designated arc striking area (105) are filled and packaged by the insulator (102).
