Problems solved by technology

[0002] In the field of high-voltage switches, the magnetic latching operating mechanism occupies an important position. At present, the magnetic latching operating mechanism on the market usually uses NdFeB permanent magnets to complete the operation and retention. However, due to the phenomenon of NdFeB demagnetization during operation, frequent operations are likely to cause mechanism failure. , which is very unfavorable for the control of high and low voltage lines

Abstract

The invention provides a single-phase magnetic latching operating mechanism, relates to the field of a high-voltage switch, and aims to provide the single-phase magnetic latching operating mechanism which still can effectively complete operation latching in frequent operations. The single-phase magnetic latching operating mechanism provided by the invention comprises an upper magnetic yoke, a magnetic sleeve, a lower magnetic yoke, a coil and a movable iron core, wherein the upper magnetic yoke, the magnetic sleeve and the lower magnetic yoke are arranged in a fitted manner in the axis direction of the magnetic sleeve in sequence to form a magnetic field space in a joint surrounding manner; the coil and the movable iron core placed in the magnetic field space; and when the coil is charged, the movable iron core can move in a direction far from or close to the magnetic field space in the axis direction of the magnetic sleeve.

Description

technical field [0001] The invention relates to the field of high-voltage switches, in particular to a single-phase magnetic holding operating mechanism. Background technique [0002] In the field of high-voltage switches, the magnetic latching operating mechanism occupies an important position. At present, the magnetic latching operating mechanism on the market usually uses NdFeB permanent magnets to complete the operation and retention. However, due to the phenomenon of NdFeB demagnetization during operation, frequent operations are likely to cause mechanism failure. , It is very unfavorable for the control of high and low voltage lines. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a single-phase magnetic holding operation mechanism that can effectively complete operation holding under frequent operations. [0004] A single-phase magnetic holding operation mechanism of the present invention includes: an upp...
