Abstract
The utility model discloses an electromagnet for controlling a switch. The outer circle of an armature of the electromagnet is coated with a graphite layer. A guide sleeve of a conducting wire bag is made of stainless steel material. The outer circle of the armature can also be coated with a molybdenum disulfide layer. The utility model is especially suitable for a servomechanism of a Zn-12 vacuum circuit breaker. The graphite or molybdenum disulfide layer carries out a well lubricating function. The hardness intensity of the stainless steel guide sleeve is high. Therefore, the armature is not easy to be clamped in the guide sleeve and can flexibly and smoothly move. The service life is long.
Description
The utility model relates to a kind of divide-shut brake electromagnet.
Used electromagnet is made up of main part such as lead bag, armature and spring; After the lead bag connects electricity, produce electromagnetic force, armature is sucked; Set back under the effect of spring during outage, because the guide pin bushing of lead bag is by softer copper material manufacturing, and armature adopts soft iron material, can't lubricate again between the guide pin bushing of armature and line bag, thus armature in guide pin bushing, move in the dumb phenomenon that sticks sometimes.
The purpose of this utility model is to design the divide-shut brake electromagnet that scribbles graphite linings, lead bag guide pin bushing employing stainless steel material on a kind of armature cylindrical for overcoming above-mentioned weak point, and armature can motion swimmingly flexibly in the guide pin bushing of lead bag.
The purpose of this utility model is achieved through the following technical solutions, and scribbles graphite linings on the cylindrical of armature, and the guide pin bushing of lead bag adopts the stainless steel material manufacturing.
Also can coat the curing molybdenum layer on the cylindrical of armature.
The utility model advantage, owing to scribble the coating of graphite or molybdenum bisuphide on the armature cylindrical, graphite or molybdenum bisuphide lubricate when armature moves in guide pin bushing, reduce friction armature also can be moved freely under low voltage making it in the guide pin bushing, improved its divide-shut brake ability and reliability, flexible and fluent motion, guide pin bushing adopts the stainless steel material manufacturing, hardness and intensity are higher, have reduced the probability that sticks in guide pin bushing and the armature two movement parts relative motions.
Description of drawings:
Fig. 1 is a divide-shut brake electromagnet schematic diagram.
Fig. 2 is the A-A cross sectional detail (removing electric wire bag and guide pin bushing) of Fig. 1.
Below in conjunction with the preferred embodiment of description of drawings the utility model, scribble graphite linings 8 on the cylindrical of divide-shut brake electromagnet armature 5; The guide pin bushing 6 of lead bag 7 adopts the stainless steel material manufacturing.Lead is packaged in 1 li of framework, and lead bag upper left side is provided with lug plate 4; The left end of armature is provided with the block 3 of restraining spring 2 positions, and the armature right-hand member is equipped with connecting rod 9, and the connecting rod end links to each other with the servomechanism of Zn-12 vacuum circuit-breaker; After the divide-shut brake electromagnet connects electricity, drive the servomechanism action of vacuum circuit-breaker at the electromagnetic force effect lower armature of lead bag, and when the divide-shut brake electromagnet cuts off the power supply, spring 2 resets the servomechanism of armature drive vacuum circuit-breaker.
