Abstract
The utility model relates to an electromagnet for an opening-closing coil of an operating mechanism of a high-voltage circuit breaker. The electromagnet consists of an insulated sleeve, a magnet yoke, an iron core, and a limit unit. The magnet yoke includes an upper magnet yoke and a lower magnet yoke; and the insulated sleeve is clamped between the upper magnet yoke and the lower magnet yoke. A coil is wound on the outer wall of the insulated sleeve according to the same direction; the iron core in a T shape is placed into the insulated sleeve; the limit unit is installed at the top of the iron core; and a tower spring is connected to the limit unit and is sleeved on the iron core. A stainless steel gasket is sleeved on the bottom of the iron core; a threaded structure is arranged at the bottom of the iron core; and a nut is matched with the threaded structure at the bottom of the iron core. And an outlet hole is arranged at the terminal of the upper magnet yoke; and a hot melt adhesive is injected into the outlet hole. When the above-mentioned structure is used, the multiple effects of long service life, small occupied space and adjustable stroke and the like can be realized.
Description
Technical field
The utility model 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 is because the impact of friction needs constantly to safeguard that 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 in the utility model 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 adopted in the utility model 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.
