Problems solved by technology

However, the inner double-toothed rack is immovable. When it is manually operated to realize the re-clamping-closing operation, it is necessary to use an external tool to rotate the incomplete gear to realize self-clutching. Manual operation is inconvenient and laborious; and manual operation is used to achieve When self-clutching, the DC motor needs to be stopped to operate, which is very inconvenient

Abstract

The invention relates to the technical field of power electronics, and discloses a quick automatic switching-on mechanism of a molded case circuit breaker and a molded case circuit breaker provided with the quick automatic switching-on mechanism molded case circuit breaker. The quick automatic switching-on mechanism comprises a direct current motor which is fixed on the circuit breaker, wherein a fixed plate is arranged above the direct current motor, and the output end is connected with a reduction gearbox; a gear fixed at the output end of the reduction gearbox; a single rack, wherein one end of the single rack is rotationally connected to a circuit breaker main mechanism lever support in the radial direction of the gear, and a tooth opening of the single rack is meshed with the gear; and a hand shifting mechanism which is fixed on the single rack, wherein the single rack can be separated from the gear by shifting the single rack towards one side. Compared with the prior art, through meshing rotation of the single rack and the gear which are rotationally connected, self-clutching of the circuit breaker is achieved, quick closing of re-buckling-closing operation is reliably achieved, electric operation and manual operation can be achieved, a direct current motor does not need to be stopped during manual operation, and efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a fast and automatic closing mechanism of a molded case circuit breaker and a molded case circuit breaker equipped with the mechanism. Background technique [0002] The opening and closing actions of traditional molded case circuit breakers need to be completed manually. However, due to the development of smart grids, a variety of assembled molded case circuit breakers appear on the market, and most of the assembled molded case circuit breakers are Cooperate with the handle. [0003] For example, Chinese patent CN207149496U discloses an energy storage electric operating device for a molded case circuit breaker, which installs the transmission mechanism above the molded case circuit breaker to cover the entire handle of the molded case circuit breaker, thereby using the transmission mechanism to drive the handle to operate. Automatic switching, however, this installation...
