Automatic-isolation apparatus of high-voltage isolation switch

The utility model discloses an automatic-isolation apparatus of high-voltage isolation switch comprising an isolation plate, guide rails, bearings, a rocker and a connecting rod. The guide rails are arranged at the left end part and the right end part of a cabinet body, and the bearings at the left and right ends of the isolation plate are arranged in the guide rails; one end of the rocker is hinged on the front door of the cabinet body, the other end is hinged with one end of the connecting rod, and the other end of the connecting rod is hinged on the isolation plate. When the front door is opened, the isolation plate is driven by the rocker and the connecting rod to move in the fracture of a high-voltage isolation switch along the guide rails; when the front door is closed, the isolation plate is driven by the rocker and the connecting rod to exit from the fracture of the high-voltage isolation switch. When the front door is completely closed, the isolation plate returns to the initial position. The utility model does not need the manual insertion and has the advantages of convenient operation and safe use. Simultaneously, the protecting grade IP2X of the cabinet body is improved, and the automatic-isolation apparatus of the high-voltage isolation switch is suitable as the isolation facility in the high-voltage isolation switches arranged by the complete equipment and the control equipment of the high voltage power distribution. 本实用新型公开了一种高压隔离开关的自动隔离装置，包括隔离板；此外还包括导轨、轴承、摇杆和连杆，所述导轨安装在柜体内的左端部和右端部，所述的安装在隔离板左端和右端的轴承设置在导轨内；所述摇杆的一端铰接在柜体的前门上，其另一端与所述连杆的一端相互铰接，连杆的另一端铰接在隔离板上。当前门打开时，通过摇杆和连杆带动隔离板沿导轨移入高压隔离开关的断口；当关闭前门时，通过摇杆和连杆带动隔离板沿导轨退出高压隔离开关的断口。前门完全关上时，隔离板回到初始位置。本实用新型无需手动插入，操作方便，使用安全，同时也提高了柜体的防护等级IP2X，适用于高压配电成套设备和控制设备配装的高压隔离开关中作为隔离设施。
