Problems solved by technology

[0006] When the circuit breaker is subjected to a strong impact, it is often under the action of an external force that the closed circuit breaker will malfunction and open. This phenomenon is never allowed in some special places.

Embodiment Construction

[0015] refer to figure 1 , which is a structural schematic diagram of the anti-misoperation device of the electric operating mechanism of the circuit breaker of the present invention.

[0016] As shown in the figure, the device includes a mounting plate 1 , a mounting block 2 , a magnet 3 , an iron sheet 4 and a slider 5 . The mounting plate 1 is the mounting base plate of the electric operating mechanism, fixed on the circuit breaker, the mounting block 2 is made of non-metallic material, fixed on the mounting plate 1 with screws, the magnet 3 is fixed on the mounting block 2 with screws; the iron sheet 4 is used Screws are fixed on the slider 5, and the slider 5 is a part of the electric operating mechanism, which drives the circuit breaker to move up and down (closing and opening). Under normal circumstances, in the closed position of the circuit breaker, the position of the iron piece on the slider is exactly at the position attracted by the magnet. In the case of strong...

Abstract

The invention relates to an anti-misoperation device of a circuit breaker electric operation mechanism (referred to as electric operator), which is used for preventing misoperation when a circuit breaker equipped with the electric operator is impacted and is characterized in that the anti-misoperation device of the electric operator comprises a mounting plate (1), a mounting block (2), a magnet (3), a iron sheet (4) and a sliding block (5). The mounting plate (1) is a mounting substrate of the electric operator and is fixed on the circuit breaker, the mounting block (2) is made of non-metallic materials and fixed on the mounting plate (1) through a screw, the magnet (3) is fixed on the mounting block (2) through the screw, the iron sheet (4) is fixed on the sliding block (5) through the screw, the sliding block (5) is one part of the electric operator, and the sliding block (5) drives the circuit breaker to carry out up and down (opening and closing) motion. When the circuit breaker is closed, the position of the iron sheet on the sliding block is just at the position which is attracted by the magnet. The magnet firmly attracts the iron sheet under the situation of strong impact, thereby preventing that the electric operator drives the circuit breaker to be impacted and further avoiding misoperation.

Description

technical field [0001] The invention relates to an anti-misoperation device of an electric operating mechanism of a circuit breaker, which belongs to the technical field of electric engineering. Background technique [0002] Low-voltage circuit breakers are mainly responsible for overload, undervoltage and short-circuit protection of distribution lines and electrical equipment. [0003] Under normal circumstances, in the low-voltage power distribution system, the closing or opening of the circuit breaker (the operation of the circuit breaker can be operated by electric operation) achieves the purpose of power supply, power failure and conversion circuit. As an external accessory of the circuit breaker, the electric operating mechanism is used for long-distance automatic opening and closing of the circuit breaker, and is suitable for places with a high degree of automation. [0004] In the case of local abnormalities in the grid, such as overload, voltage loss or undervoltag...
