Abstract

The invention relates to the technical field of electric equipment and discloses a grounding interlocking mechanism for a low voltage plastic casing switch, which is a grounding device for a low voltage switch. A copper bar, an insulating plate and a grounding swinging piece are arranged on a bracket; a grounding bracket is arranged on the copper bar; the plastic casing switch is arranged on the bracket; a switch pull plate is arranged below the plastic casing switch; a grounding switching piece is arranged inside the plastic casing switch; a grounding pull plate is arranged below the grounding swinging piece; a connecting plate is arranged between the switch pull plate and the grounding pull plate; and the lower part of a frame body is provided with a magnetic strip bracket on which a magnetic strip pressing plate is arranged. The grounding interlocking mechanism has obvious breaking indicating points; with the adoption of the grounding interlocking mechanism, the maintenance safety of switch subordinate lines is guaranteed, namely that the safety performance of the grounding switch of a plastic casing circuit breaker is significantly improved; and meanwhile, the operation safety of maintenance staff is greatly improved; and the grounding interlocking mechanism plays the role of guaranteeing the personal safety of maintenance staff and operators.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a grounding interlocking mechanism of a low-voltage plastic case switch, which is a low-voltage switch grounding device. Background technique [0002] The low-voltage switch grounding device is mainly used for equipment maintenance. In order to prevent sudden calls during the maintenance process, it can carry the specified abnormal current within the specified time. Therefore, both ends of the maintenance equipment must be grounded. The grounding switch is generally grounded on the output load side. At the same time, close the grounding switch of the equipment, which can prevent electric shock accidents caused by sudden calls. In addition, it can discharge the remaining charge, which is conducive to maintenance safety. Electric shock accidents caused by power transmission. The traditional molded case circuit breaker does not have a grounding device, which prevents ...
