LINEAR CONTACT ASSEMBLY FOR HIGH VOLTAGE DISCONNECTORS (OPTIONS), arc suppression device for this disconnectors and disconnectors high voltage (OPTIONS)

摘要

The invention relates to electrical devices. Linear contact assembly for disconnector high voltage includes mounted on the support base, the first support bushing at the upper free end of which fixed contact jaws bus bar and the second support bushing at the upper free end of which is fixed busbar with pivotally mounted contact knife with a contact pad to interact with contact jaws on the first post insulator. Contact knife is pivotable in a vertical plane of the contact pad placement position in the contact jaws on the first support insulator in the seating position of the contacting pad in the contact jaws grounding rail, wherein the contact blade is provided with additional insulator having one end connected with its rotation drive in a vertical plane and the other end with a contact blade at a point located between the axis of rotation of the knife and the seat of the contact pads on this knife. The node is provided with arc suppression device designed as fixed on a contact blade spring, the end coil of which one side of the spring is formed as a resiliently deformable rod laid along the contact blade with the release of its end beyond the outer blade length and resiliently bending upward from this knife. Contact jaw grounding rail mounted on the support base on the side accommodating the second support insulator and below the attachment of the support insulator on this basis, and the second support insulator and an additional insulator disposed obliquely towards the first support insulator. 7 yl.
