DES(X)1-12 AC high-voltage isolating switch
DES(X)1-12 indoor AC high-voltage isolation switch is our independent research and development of patented products. Patent number: 03238364.9 and 200730141258.4, is a new type of air insulation isolation-grounding switch. The closing and grounding static contacts of the isolation-grounding switch are cast in the insulating seat, and the position status of the switch is clear at a glance. Isolation-grounding switch is especially suitable for 12kV miniaturization, A, B, C rear middle front layout of the switch cabinet. The isolating-earthing switch is not only easy to install, but also can separate the bus room and the switch room without gap after installation. This type of isolation-grounding switch is equipped with a special spring mechanism, and the opening and closing of the switch is stored by the spring of the mechanism to ensure the opening and closing speed and position of the switch, regardless of the magnitude and speed of the operating force, and the operation is simple and reliable. It completely solves the disadvantages that the opening and closing of isolating switches at home and abroad depends on the impact of human acceleration and the insertion of positioning pins after they are in place.

DES(X)1-12 series isolating switch can be equipped with a special interlocking head to realize mechanical interlocking between cabinets. Only the switch with interlocking head can be closed, and the interlocking head cannot be removed after closing, and vice versa. Generally, three switches are equipped with two interlocking heads, three switches can only be combined with two at most, two switches are equipped with one interlocking head, and only one switch can be closed. The program lock between cabinets can also be realized through a special interlocking lock head, so that the isolating switch can be opened and closed according to the established procedure.
