Abstract
The outdoor AC high-voltage three-phase linkage isolating switch that the utility model provides, each connection one plane hinge quadric chain between three-phase intermediate standoff, intermediate standoff is provided with insulator axis of rotation for swinging the parallel fork of symmetrical centre, and parallel promotion connecting rod is connected to the plane hinge quadric chain forming alternate identical parallelogram between two adjacent forks.There is in the technical program the technological merit that mechanical strength is high, ensure that the accuracy of this switch, reliability and stability.
Description
Technical field
The utility model relates to the outdoor high-voltage alternating current isolating switch having and horizontally rotate double-fracture conductive structure, particularly relates to the interlock transmission that threephase switch lock is dynamic.
Background technology
Below state with GW7-252 type outdoor high-voltage alternating current isolating switch product for typical case, but the protection range of Ben Wenben is not limited to this statement example.
GW7-252 type outdoor high-voltage alternating current isolating switch is responsible for the non-loaded circuit switching of three-phase alternating current and by high voltage bus, the electrical isolation between circuit breaker and live high voltage circuit of overhauling, its standard specification is: insulation distance, dielectric strength, mechanical strength and Dynamic stability that separating brake cut-off point is obvious, enough.
The three-phase lock of existing three-phase ganged outdoor AC high-voltage isolating switch moves Drive Structure and adopts alternate chain connection list connecting rod construction, the pin joint of alternate monotroded bar is arranged on the node of motor connecting lever drive link and the driven connecting lever connecting rod of rotating insulated son, and node bottom connects longitudinal fork.The technical problem underlying that this structure exists is: handle bad mechanical strength, in rotary actuation, the alternate monotroded bar be articulated with initiatively between phase and side phase bears very high pulling torque, and occurs crimp and torsional deformation, cause separating brake, close a floodgate not in place, have a strong impact on the reliability of switch.
Summary of the invention
Goal of the invention of the present utility model be to provide a kind of alternate mechanical linkage intensity high, ensure the action of three-phase lock synchronous, accurately, stable, outdoor AC high-voltage three-phase linkage isolating switch reliably.The outdoor AC high-voltage three-phase linkage isolating switch technical scheme that the utility model provides, its main technical content is: a kind of outdoor AC high-voltage three-phase linkage isolating switch, each connection one plane hinge quadric chain between three-phase intermediate standoff, intermediate standoff be provided with parallel, with insulator axis of rotation for swinging the parallel fork of symmetrical centre, parallel promotion connecting rod is connected with, at the plane hinge quadric chain of the identical parallelogram of alternate formation between two adjacent forks.
In outdoor AC high-voltage three-phase linkage isolating switch technical scheme disclosed in the utility model, threephase switch action combined operation have employed synchronously driven plane hinge quadric chain, its mechanical strength is high, three-phase ganged action load can be born reliably, there is the technique effect that stability is high, and then ensure that combined floodgate, accuracy that separating brake lock moves position, ensure that the accuracy of this switch, reliability and stability.
Accompanying drawing explanation
Fig. 1 and Fig. 2 is that between the utility model three-phase intermediate standoff, interlock structure master looks and plan structure figure respectively.
Embodiment
Outdoor AC high-voltage three-phase linkage isolating switch disclosed in the utility model, its three-phase ganged structure example structure as shown in drawings, the intermediate standoff 4 of its mesophase spherule is driven by motor and horizontally rotates.Intermediate standoff 4 drives intermediate standoff 5, the 6 synchronous rotary lock of both sides phase to move through plane hinge quadric chain.Described plane hinge quadric chain: three-phase intermediate standoff 4,5,6 is equipped with insulator axis of rotation as swinging parallel interlock fork 1a, 1b, 1c of symmetrical centre, the hinged parallel promotion connecting rod 2,3 in outer end between two adjacent fork 1a and 1b or 1a and 1c, the common plane hinge quadric chain forming two adjacent alternate identical parallelogram.
Claims (1)
