High-voltage electrical equipment control cabinet observation window structure

An observation window structure of a high-voltage electrical equipment control cabinet comprises a protective frame, a transparent plate, a permeable plate, a filter plate and a contact pin, the transparent plate, the permeable plate and the filter plate are in sliding fit with a slot of the protective frame, and the contact pin penetrates into the slot from one side of the protective frame to support the transparent plate, the permeable plate and the filter plate to open and close an observation opening. The high-voltage electrical equipment control cabinet observation window overcomes the problem that an original high-voltage electrical equipment control cabinet observation window can only be used for observation in an environmental factor conversion process and cannot change functions along with environmental changes, and has the advantages of being simple in structure and capable of being used for ventilation, heat dissipation or dust prevention in environmental factor conversion. 一种高压电气设备控制柜观察窗结构，它包括防护框、
