Abstract

The invention relates to an electromagnet for a high-voltage circuit breaker operating mechanism opening and closing coil. The electromagnet comprises an insulating sleeve, a magnetic yoke, an iron core and a spacing piece, wherein the magnetic yoke further comprises an upper yoke and a lower yoke; the insulating bushing is sandwiched between the upper yoke and the lower yoke; the coil is wound on the outer wall of the insulating sleeve in the same direction; the iron core protrudes into the insulating sleeve; the iron core is T-shaped; the spacing piece is mounted at the top of the iron core; the spacing piece is connected to the top of the iron core; a tower spring is connected to the spacing piece; the tower spring is sleeved on the iron core; a stainless steel gasket is sleeved on the bottom of the iron core; the bottom end of the iron core is provided with a threaded structure which is matched with threaded structure at the bottom end of a nut iron core; a wire outgoing hole is formed on a wiring terminal of the upper magnetic yoke; and hot melt adhesive is filled in the wire outgoing hole. By adopting the above structure, several effects of long service life, small occupying space, adjustable travel and the like can be achieved.

Description

A kind of high-voltage breaker operation mechanism divide-shut brake coil electromagnet

Technical field

The present invention relates to a kind of high-voltage breaker operation mechanism divide-shut brake coil electromagnet.

Background technology

In the electromagnet that uses in present stage, electromagnet since the impact of friction need constantly to safeguard, useful life is short, and space hold is slightly large, and electromagnet can't regulate, and can not satisfy the demand of multiple aspect.

Summary of the invention

Technical problem to be solved by this invention provides a kind of long service life, little, adjustable electromagnet takes up room.

In order to solve the problems of the technologies described above, the technical solution used in the present invention is: electromagnet, its innovative point is to comprise insulating sleeve, yoke, iron core, described yoke is divided into again upper magnet yoke and lower yoke, insulating sleeve is clipped between upper magnet yoke and the lower yoke, be fixed with screw between upper magnet yoke and the lower yoke and be connected, coil is wrapped in the outer wall of insulating sleeve by same direction, iron core stretches in the insulating sleeve and iron core and insulating sleeve are matched in clearance, the T-shaped shape of iron core, have one spacing at the top of iron core, be connected with the tower spring on spacing, the tower spring is enclosed within on the iron core, the other end of tower spring is against on the upper magnet yoke, lower yoke is passed in the bottom of iron core, bottom at iron core is threaded structure, nut is positioned at the outside of lower yoke and the helicitic texture of iron core bottom matches, terminals at upper magnet yoke have a wire hole, be marked with PUR in the wire hole, hollow position in the middle of upper magnet yoke and lower yoke is installed near a spacing end all bearing, described bearing is self-lubricating bearing, and cover has a stainless steel gasket on the bottom of described iron core, and stainless steel gasket is between the first half and lower yoke of iron core.

Use above-mentioned device, electromagnet itself is with self-lubricating structure, Maintenance free, long service life, and the space hold of electromagnet is little, easy for installation, the space characteristics of compact layout, be convenient to miniaturization, electromagnet can meet the different needs by adjusting nut, the tower spring structure of use, because the mechanical characteristic of tower spring, can guarantee the electromagnet steady operation, increase stainless steel gasket at iron core between the lower yoke, can play the effect in isolation magnetic field.
