Claims

[Scope of utility model registration request]

(1) Equipped with a main current-carrying contact part and an arc contact part having a coil that generates a magnetic field that rotates the arc during opening, and the arc contact part has a first arc contact and a second arc contact provided at both ends of the coil, respectively. It has a third arc contact that switches contact between the two contacts, and when the disconnection section is opened, the third arc contact changes from the first arc contact to the second arc contact after the main energizing contact section is completely opened. A disconnector configured to insert a coil into a circuit between contacts by switching.

(2) The coil is wound around the outside of the insulating tube, and the first arc contact and second arc contact at both ends are fixed inside the insulating tube, and the creepage distance is extended to the adhesive surface between both contacts and the insulating tube. A disconnector according to claim 1 of the utility model registration claim, which is provided with a gap.
