Arc suppression coil

Abstract

The invention discloses an arc suppression coil, which comprises an oil immersion box, wherein the upper part of the oil immersion box is fixedly provided with a sealing seat; the oil immersion box isfull of insulation oil; a rotation rod is movably installed in a rotation seat; one end, which is far away from the rotation seat, of the rotation rod is fixedly provided with a hexagonal cooperationseat; one end, which is far away from the hexagonal cooperation seat, of a first damping spring is fixedly installed in a damping hole arranged on a spring cooperation seat; the upper side and the lower side of the cooperation seat are independently fixedly provided with a second damping spring; a damping sleeve is movably inserted in the rotation rod; the upper end and the lower end of the damping sleeve are fixedly provided with one pair of iron core permanent seats; iron cores are positioned on two sides of the damping sleeve; a winding group is arranged out of each iron core; and a sliding turn-skipping bar and a sliding turn-skipping rod are in cooperation connection. The arc suppression coil has a good cooling effect, the transverse wave and the primary wave of an earthquake can beeffectively filtered during the earthquake, and the arc suppression coil can be guaranteed to normally work in the earthquake, and is especially suitable for earthquake-prone regions.

Description

technical field [0001] The invention relates to the technical field of arc suppression coils, in particular to an arc suppression coil. Background technique [0002] A continuous on-load turn-adjusting arc suppression coil device with the application number "CN201720222616.2" in the prior art includes a double-hole fixing seat and a supporting foot, and a terminal is arranged above the double-hole fixing seat. An iron core is arranged below the coil anti-vibration pad, a low-power winding is arranged outside the iron core, a high-power winding is arranged under the low-power winding, and a connecting rod is arranged outside the high-power winding. The bottom of the iron core is provided with a fixed frame, and the lower part of the fixed frame is provided with an iron core mounting seat, which breaks through the traditional coil manufacturing process and adopts a special structure of "double-wrapped wire" to divide the coil into "high power" and "low power". Two kinds of wi...

Problems solved by technology

[0003] However, the above-mentioned continuous on-load turn-adjusting arc-suppression coil device still has obvious defects during use: 1. The above-mentioned device does not have an effective cooling device, and it needs to be equipped with corresponding shelter buildings during installation, and the installation and construction period is long; 2. The above device only uses coil anti-shock pads for shock absorption. The coil anti-shock pads will gradually harden and lose elasticity over time, and the shock absorption effect is not good. For mountainous areas where earthquakes occur frequently, this type of shock absorption method is difficult to ensure that the arc suppression coil Can still work normally during an earthquake
