Abstract

The invention provides a pusher group applicable to double-steel-magnet differential relays and a using method thereof, and relates to a pusher group. The invention aims to solve the problem that the existing double-steel-magnet differential relay pusher group only contacts reeds on one side. According to the pusher group applicable to double-steel-magnet differential relays in the invention, surface contact between pushers and movable reeds is realized by clamping the edges of the movable reeds from two sides, and the means of self-return of the movable reeds is changed into the means of armature-driven return so as to suppress collision bounce between the movable reeds and a back static reed in the release process of a double-steel-magnet differential relay. According to the using method of the pusher group applicable to double-steel-magnet differential relays, an armature applies pressure to the movable reeds by making use of holding force provided by steel magnets in the release position. The anti-vibration performance is improved, the pull-in voltage is reduced, pull-in is facilitated, the sensitivity of an electromagnetic system is improved, and the phenomenon of two-step pull-in is inhibited.

Description

technical field [0001] The invention relates to a pusher group, in particular to a pusher group suitable for a double magnetic steel differential relay. Background technique [0002] Double magnetic steel differential relay has the advantages of small magnetic potential, high sensitivity, and stable operating point, and is widely used in missiles, launch vehicles, artificial satellites, spacecraft, space shuttles and their supporting ground measurement and control equipment to complete signal transmission and execution control , System power distribution and other functions. In order to realize the kinematic connection between the electromagnetic system and the contact spring system and reduce the bouncing caused by the collision motion of the reed, it is very important to design the proper structure of the pusher group. However, most of the currently used pusher group structures are only in contact with the reed on one side, which has the following disadvantages: First, af...
