AI Technical Summary

Technical Problem

The existing high-voltage distribution cabinet cannot switch states when the cabinet door is opened, which makes maintenance and detection difficult and there is a risk of electric shock.

Method used

The high-voltage distribution cabinet is protected by a delay interlocking based on the smart grid. By setting up a door opening locking component between the pulley and the cabinet door, the cabinet door is opened when the pulley is closed, and the current from the electrical components inside the cabinet body is directed to the ground through the grounding component and the adapter component to ensure that the distribution cabinet is in a powerless state when the cabinet door is opened.

Benefits of technology

It improves the safety of the distribution cabinet, avoids the risk of electric shock caused by misoperation, simplifies the maintenance and inspection process, and improves the detection efficiency.

Abstract

The invention discloses a delay interlocking protection high-voltage power distribution cabinet and method based on an intelligent power grid, and relates to the technical field of high-voltage power distribution cabinets, the delay interlocking protection high-voltage power distribution cabinet comprises a cabinet body, electrical elements in the cabinet body, a cabinet door rotatably installed on the cabinet body, and a power supply connection module rotatably provided with a pull switch; the power supply connection module is fixedly installed in the cabinet body, and the side edge of the cabinet body is provided with a strip-shaped through hole. The device has the advantages that when interlocking protection between the cabinet door and the power supply connecting module is carried out, the cabinet door is opened after a power supply is turned off, the safety is higher, meanwhile, a pull switch is locked after the cabinet door is opened, the situation that the power supply connecting module is started due to mistaken touch is avoided, in addition, after the cabinet door is opened, opening and closing of the power supply connecting module can be controlled freely, and the safety is higher. In addition, after the power supply is turned off, the residual current in the electrical elements can be reduced by grounding and increasing the resistance in the circuit loop, and the circuit protection device has the advantage of protecting the circuit.
