Detailed Description
Examples
Fig. 1 is for realizing above-mentioned purpose, the utility model provides a mechanical interlocking structure for prepayment combination mutual-inductor and isolator, including link gear 4, right angle slide bar 3, horizontal fixed sleeve 2 and stop gear 7, 4 lower extremes of link gear articulate on the deciliter action bars 6 of prepayment combination mutual- inductor 5, 4 upper ends of link gear are articulated with 3 one end of right angle slide bar, the other end of right angle slide bar 3 sets up in stop gear 7, a right angle arm of right angle slide bar 3 passes through horizontal fixed sleeve 2 and sets up on the isolator shell, another right angle arm of right angle slide bar 3 passes the shell of isolator and the guide vane 71 in stop gear 7, stop gear 7 sets up on the isolator, horizontal fixed sleeve 2 is fixed on the isolator shell.
The limiting mechanism 7 comprises a guide sheet 71 and a limiting sheet 72, the guide sheet 71 is fixed in the isolating switch, the limiting sheet 72 is fixed on the rotating shaft 1 of the isolating switch, and the limiting sheet 72 is located between the guide sheet 71 and the shell of the isolating switch.
Horizontal through holes 711 are formed in the guide sheet 71 and the isolating switch shell, the two horizontal through holes 711 are arranged oppositely, and the other right-angle arm of the right-angle sliding rod 3 penetrates through the two horizontal through holes 711.
The linkage mechanism 4 comprises an insulating pull rod 42 and a crank arm 41, the lower end of the insulating pull rod 42 is hinged to the opening and closing operating rod 6, the upper end of the insulating pull rod 42 is hinged to the lower end of the crank arm 41, the corner of the crank arm 41 is hinged to the shell of the isolating switch, and the upper end of the crank arm 41 is hinged to the right-angle sliding rod 3.
The opening and closing operating rod 6 is pressed leftwards, so that the mechanical linkage is in an 'opening' state, the right-angle sliding rod 3 is driven by the insulating pull rod 42 and the crank arm 41 to slide rightwards in the horizontal fixing sleeve 2 and move to the rightmost end of the horizontal through hole 711. At this time, if the isolating switch is in an on state, the limiting piece 72 is located below the right-angle sliding rod 3, the right-angle sliding rod 3 just blocks the limiting piece 72, and the rotating shaft 1 cannot rotate at this time, so that the knife switch of the isolating switch is in a locked state. If the isolating switch is in an off state at this time, the limiting piece 72 is positioned above the right-angle sliding rod 3 and is also clamped by the right-angle sliding rod 3, so that the rotating shaft 1 cannot rotate, and the knife switch is locked.
The opening and closing operating rod 6 is pressed rightwards, so that the mechanical linkage is in a 'separating' state, and the right-angle sliding rod 3 slides leftwards and moves to the leftmost end of the horizontal through hole 711. At this time, the right-angle sliding rod 3 will not affect the movement of the limiting piece 72, and the isolating switch can be freely opened and closed.
Therefore, the utility model adopts the above structure a mechanical interlocking structure for prepayment combination mutual-inductor and isolator can lock isolator's state, prevents the casualty accident that leads to because of the high tension arc of isolator department when workman's operation and maintenance, and is easy and simple to handle, the installation of being convenient for.
