Integrated high-low voltage protection box

The invention relates to the technical field of mining distribution equipment and particularly relates to an integrated high-low voltage protection box. The integrated high-low voltage protection box is characterized by comprising a transformer and a high-low voltage protection box. The transformer is internally provided with a high voltage lead and a low voltage lead which are both guided to one side of the high-low voltage protection box. The high-low voltage protection box is internally provided with a high voltage input end and a low voltage output end. The high voltage input end is connected with the high voltage lead of the transformer. An isolation switch and a breaker are arranged between the high voltage input end and the high voltage lead. The low voltage lead and a low voltage output end low voltage transmission cable are connected. The high-low voltage protection box is also internally provided with a comprehensive protection unit and a control transformer. A high voltage input line and a low voltage output line are connected with the comprehensive protection unit. The invention provides the integrated high-low voltage protection box which has high performances, which is multifunctional and digital, and which is small in occupation area.
