The invention discloses a cabinet door safety interlocking device and method for a frequency converter cabinet. The device comprises an equipment two-dimensional code disposed on the peripheral surface of the frequency converter cabinet, a security assembly which is disposed at a cabinet door and is in communication connection with the equipment two-dimensional code, and a lock control assembly which is in communication connection with the security assembly and the equipment two-dimensional code; the equipment two-dimensional code is used for providing a special portal for cabinet door opening and closing application and recording an operation log of the opening and closing of the cabinet door. The device two-dimensional code is used for submitting the cabinet door opening and closing application of the frequency converter cabinet and recognizing the operation log of the opening and closing of the cabinet door; the security operation and electromagnetic opening and closing of the frequency converter cabinet are carried out based on the cabinet door opening and closing application, and non-contact opening and closing of the cabinet door of the frequency converter cabinet are achieved when a main power source and an energy storage capacitor have electrical dangers, and the control safety of special personnel is ensured.
Description
technical field [0001] The invention relates to the technical field of frequency converter cabinet safety, in particular to a cabinet door safety interlock device and method for a frequency converter cabinet. Background technique [0002] In the application of modern high-power frequency conversion devices, with the increase of the power of the traction motor, the voltage level of the frequency converter controlling the traction motor is getting higher and higher, and the requirements for the safe operation of personnel are also getting higher and higher. There is not enough safety awareness during the operation process. When there is still high voltage in the inverter, the door of the inverter cabinet is opened and closed at will, which brings double safety hazards to personnel and equipment. Although there are high-voltage indicators and equipment running Visual reminders such as status warnings can remind personnel to pay attention to the high-voltage operation of the equ...
