Problems solved by technology

The existing releases are generally electromagnetic releases, which are easily affected by the interference of external magnetic fields, and the tripping is unstable, which affects the normal operation of mechanical circuit breaking to a certain extent.
In addition, the existing electromagnetic release adopts the traditional laser marking "N" pole and "S" pole, which has complicated procedures and low polarity accuracy

Abstract

The invention relates to a release matched for a residual current operated circuit breaker, which comprises an enclosure, wherein an upper cover board is configured to the enclosure; a coil skeleton for installing a coil and a magnetic steel are respectively arranged at both sides inside the enclosure; the coil and the magnetic steel are connected by a middle magnetic yoke; an armature is arranged below the magnetic yoke, and an ejector rod extending out of the plastic enclosure is arranged at the bottom of the armature; one end part of the magnetic yoke is positioned at the upper part of the coil skeleton; a disk-shaped magnetic steel is fixed at the other end part of the magnetic yoke, which is folded downwards; a positioning groove is formed on the upper end face of the disk-shaped magnetic steel, and polarities of N and S poles are directly magnetized by thermal processing; and an armature is arranged below the other end part of the magnetic yoke, which is folded downwards, and the armature extends to be arranged below the coil skeleton and is connected with a magnetic movement shaft vertically arranged in the middle of the coil skeleton. The release has the characteristics that the release is simple in structure and convenient and reliable to use; the production process is simplified; polarity accuracy is improved; action reliability of releasing is higher; and the like.

Description

technical field [0001] The utility model relates to a tripper matched with a residual current action circuit breaker, which belongs to the technical field of low-voltage electrical equipment. Background technique [0002] The trip unit is a device that is mechanically connected or integrated with the circuit breaker to release the holding mechanism and automatically disconnect the circuit breaker. The existing releases are generally electromagnetic releases, which are easily affected by the interference of external magnetic fields, and the tripping is unstable, which affects the normal operation of mechanical breaking to a certain extent. In addition, the existing electromagnetic tripper adopts the traditional laser marking "N" pole and "S" pole, which has complicated procedures and low polarity accuracy. Utility model content [0003] The purpose of the utility model is to overcome the deficiencies of the existing technology, and provide a simple structure, convenient an...
