Embodiment

[0038] This embodiment provides a DC1500V non -polar magnetic blowout extinguishing DC isolated switch, such as figure 1 Show, including switching items 1. The contact system, arc extinguishing area 5 and magnetic parts 6.

[0039] Switch body 1, such as figure 2 It shows the cover plate 17 and base 16 of the upper and lower buckle settings, the inner surface of the cover plate 17 and the base of the base 16, respectively. There is a static contact 3 between the area 5. like Figure 5 and 6 Show, the base 16 and the cover plate 17 are formed on the installation slot inserted in the installation bracket 9. In this embodiment, the arc extinguishing region 5 is formed on the switch body 1 through injection molding. by Figure 10 and 11 For example, according to the Apeli formula F = BIL, the magnetic field direction of magnetic parts 6 is perpendicular to the direction of the current I. The arc 18 moves to the base 16 direction (that is, down) under the action of the magnetic field for...

Abstract

The invention provides a DC 1500V non-polar magnetic quenching type DC isolation switch. The DC isolation switch comprises a switch body; the contact system is arranged on the switch body and comprises a static contact and a moving contact which is in contact connection with the static contact or is separated from the static contact; the arc extinguishing area is provided with arc extinguishing ribs at two sides and is arranged on the switch body; and the magnetic piece is arranged on the switch body and is suitable for blowing electric arcs generated in the opening and closing process of the moving contact and the static contact to the arc extinguishing rib area. By arranging the arc extinguishing rib area, the arc can be segmented, the arc voltage can be increased, the arc can be quickly extinguished, and the switch is suitable for being used in DC1500V.

Description

Technical field [0001] The invention involves the field of DC separation technology, which specifically involves a DC1500V non -polar magnetic blowout extinguishing DC isolation. Background technique [0002] DC isolated switch is used in the power distribution equipment of industrial enterprises for non -frequently connecting and segregated circuits and electrical isolation. It is widely used in power distribution systems and automation systems of construction, power, petrochemical and other industries. [0003] The existing DC isolation is mainly used to connect the loop control of lower voltage and lower power. With the improvement of the voltage, the arc generated during the switching process is becoming more and more difficult to extinguish. It seriously restricts the DC isolation isolation. Development in the field of higher voltage use. Invention content [0004] Therefore, the technical problem to be solved by the present invention is to overcome the deficiencies that ar...
