The invention discloses a switchgear operating hole padlock device with anti-arcing capability which comprises a face shield, a switchgear door plate, a fixed plate and a movable baffle plate. The middle part of the face shield is provided with an airfoil hole B. The face of the face shield in contact with the switchgear door plate is provided with a connection structure. The switchgear door plate is provided with an airfoil hole A and an installation hole. The fixed plate comprises a plate A, a plate B and a spring. The moveable baffle plate is provided with an opening which matches the spring. The face shield penetrates the installation hole on the switchgear door plate through the connection structure so that it is connected firmly with the fixed plate. The moveable baffle plate is embedded between the switchgear door plate and the fixed plate. According to the invention, the structure of the device is simple. It can be conveniently installed and it is good looking. The device can provide a firm structure and is highly practical in use.
Description
technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a padlock device for an operation hole of a switch cabinet with arc-resistant capability. Background technique [0002] Generally, switch cabinets require that the switch elements in the cabinet can only be operated when the cabinet door is closed, and the operation hole on the switch cabinet door is an essential structure of the switch cabinet body. When the cabinet is in the live running state, the operator is not allowed to operate at will. At the same time, the switch cabinet is required to have the combustion particles and hot gas generated when the internal failure occurs, which will not cause harm to the surrounding personnel. [0003] There are two types of existing switchgear operating hole padlock devices: 1. Installed on the outside of the cabinet door, with poor or no arc resistance; 2. Installed on the inside of the cabinet door, with arc resistance, but Bot...
