Problems solved by technology
[0003] The general fast operating mechanism can reach a very high speed under the instantaneous action of electromagnetic repulsion, but at such a speed, its locking and tripping become particularly difficult
Because the movement speed is too fast, it will cause huge impact and mechanical wear on the locking device during braking and locking, and even cause the locking device to fail after repeated operations

Embodiment Construction
[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0018] refer to Figure 1 to Figure 4 As shown, the present invention discloses a locking device for a quick operation mechanism, which includes a fixed assembly part and a moving assembly part. The fixed plate 7 between the coil 1 and the driving coil 10, the moving component part includes the gland 2, the locking mechanism and the fork-shaped locking lever 6 used in conjunction with the locking mechanism, and the gland 2 is concave Disk-shaped structure; the fixed plate 7 is provided with a guide hole for the lower connecting rod of the fork-shaped lock rod 6 to pass through and coaxial with the tripping coil 1, and the left and right sides of the fork-shaped lock rod 6 protrude from the side bottom An anti-rotation positioning device 11 is also fixedly arranged between the end and the fixed plate 7, so that the fork lock bar 6 can only move along the norm...

The invention discloses a locking device for a quick operating mechanism. The locking device comprises a fixed component part and a moving component part, wherein the fixed component part comprises atrip coil, a drive coil and a fixed plate arranged between the trip coil and the drive coil; the trip coil and the drive coil are coaxially arranged; the moving component part comprises a gland, a locking mechanism and a fork-shaped lock rod matched with the locking mechanism for use; a guide hole through which a lower connecting rod of the fork-shaped lock rod passes and which is coaxial with thetrip coil is formed in the fixed plate; and the bottom end of the lower connecting rod of the fork-shaped lock rod is fixedly connected with a repulsion plate arranged at the upper part of the drivecoil and a reset device is also arranged at the bottom end of the lower connecting rod. After the locking device disclosed by the invention is applied to the quick operating mechanism, the motion characteristics of the quick operating mechanism are not affected; and at the end of motion of the mechanism, the locking device is assisted in completion of a locking action through the breaking rapidityof the mechanism, so that the locking and tripping reliability of the quick operating mechanism is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of circuit breakers, and in particular relates to a locking device for a quick operating mechanism. Background technique [0002] The quick operating mechanism is a new type of operating mechanism made using the principle of eddy current electric repulsion. It is more and more used because of its simple structure and fast opening speed. [0003] The general fast operating mechanism can reach a very high speed under the instantaneous action of electromagnetic repulsion, but at such a speed, its locking and tripping become particularly difficult. Because the movement speed is too fast, it will cause huge impact and mechanical wear to the locking device during the braking and locking process, and even cause the locking device to fail after repeated operations. Contents of the invention [0004] The object of the present invention is to design a locking device for a fast operating mechanism based on the defic...
