Title: DOUBLE-BLADED HIGH-VOLTAGE DISCONNECTOR
Abstract:
A double-bladed high voltage disconnector, comprising a clamping base (1), insulators (2) mounted symmetrically on two sides of the clamping base (1), contact seats (3) fixedly mounted on the tops of the insulators (2), strike plates (4) provided on the contact seats (3), a spindle rod (5) mounted on and penetrating the middle of the top surface of the clamping base (1), and a blade drive apparatus (6) mounted on a side wall of the spindle rod (5). Two S-shaped blades (61) and two linear blades (68) respectively form or break connections between the strike plates (4), and can effectively and stably control current flow; a matching driven gear (64), drive gear (63) and beveled gear shaft (65) are used to cause the S-shaped blades (61) to rotate in opposite directions, enabling use as a disconnector; by means of a rotating plate (66) and utilizing principles of eccentric motion, the linear blades (68) connect to matching contact blocks (12), effectively preventing a virtual connection from being made when using one blade; a contact pin (62) is effectively prevented from falling out of a pin hole by means of a limiting pin (13) mounted at the pin hole (11).
