Description
Technical field
The utility model relates to the three-phase outdoor AC high voltage isolator having and horizontally rotate fracture conductive structure.
Background technology
Below state with GW7-252 type outdoor AC high-voltage isolating switch product for typical case, but the protection range of Ben Wenben is not limited to this statement example.
GW7-252 type outdoor AC high-voltage 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, especially can reliable switch actuating under various environment and bad weather.
Existing three-phase ganged outdoor AC high-voltage isolating switch, as shown in Fig. 1 structure, the intermediate standoff lock driving mechanism of middle part electricity mutually form comprise bearing 8, the driven connecting lever of bearing axle and follower link, motor shaft drives connecting lever and drive connecting rod thereof, follower link drives the interlock connecting lever connecting three-phase ganged single pole 2, and three-phase ganged bar interlock connecting lever drives follower link and the bearing of subordinate.The technical problem that this structure exists needs stronger lock to move driving force, operation is comparatively heavy, and mechanism operation load is comparatively large, and lock driving mechanism and three-phase ganged mechanism all need to bear comparatively big-movement moment of torsion, easily cause deformation and combined floodgate and sub-switching operation cannot be completed, affecting the flexibility that lock is dynamic; In addition, interlock connecting lever is upper and lower longitudinal extent actuating parts, bedframe crossbeam can only adopt unenclosed construction, weaken the support strength of framework, and be exposed in the environment such as dust pollution, acid-rain corrosion, substantially reduce the useful life of product, in some bad weather, as wrapped up by ice and snow in ice and snow sky, sleet, rain and snow mixed, causing isolating switch to lose efficacy, incuring loss through delay electric power first-aid opportunity.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of switch to handle the outdoor three-phase linkage alternating-current high-voltage isolation switch that load is little, light, operating reliability is high.The outdoor three-phase linkage alternating-current high-voltage isolation switch technical scheme that the utility model provides, its main technical content is: a kind of outdoor three-phase linkage alternating-current high-voltage isolation switch, the composition of the rotating insulated sub-lock driving mechanism of central authorities comprises the horizontal connecting lever of motor shaft and the horizontal connecting lever of bearing axle, between two horizontal connecting levers, a hinged connecting rod is formed jointly, and the fork of three alternate link gears is fixed on central rotating insulated son.The rotating insulated son of central authorities described in this programme be three-phase isolation switch middle part mutually electricity the rotating insulated son in centre.
In above-mentioned overall technical architecture, three alternate link gears are be connected in the parallel hinges quadric chain between the rotating insulated son of three-phase, each mutually rotating insulated son is all fixed with a fork, described fork is formed for symmetrical centre extends with its rotating insulated sub-axis of rotation, the parallel hinges quadric chain between the fork of two adjacent rotating insulated sons described in hinged two interlock connecting rods formations.
In outdoor three-phase linkage alternating-current high-voltage isolation switch technical scheme disclosed in the utility model; simplify the composition structure of lock driving mechanism; its horizontal drive rotating mechanism makes the dynamic operation of lock more light, flexible; and isolating switch bedframe crossbeam can adopt enclosed construction; enhance the mechanical support intensity of framework; protection internal mechanism exempts from the erosion such as dust pollution, acid rain; still effectively operation can be moved by lock in the ice and snow such as sleet, rain and snow mixed weather; global reliability is high, and useful life extends greatly.

Embodiment
The utility model this section be with model be GW7-252 type outdoor high-voltage alternating current isolating switch in adopt the technical solution of the utility model for embodiment is to illustrate technology contents.
GW7-252 type outdoor high-voltage alternating current isolating switch is for illustrating structure example, its structure comprises bedframe, three insulators of every electricity are mutually that a phase component is not vertically fixed on three road fixed cross beams 1 of bedframe, insulator top is provided with the conductive contact assembly that lock moves cooperation, wherein moving contact swing arm 9 is fixed on the rotating insulated sub-top, centre often organized mutually, and the rotating insulated son in centre of middle phase line is central rotating insulated son.As shown in Figure 1, the rotating insulated sub-lock driving mechanism of central authorities is arranged between its bearing 8 and motor shaft 7, and composition comprises articulated linkage 6 between the horizontal connecting lever of bearing axle 4 and the horizontal connecting lever 4,5 of the horizontal connecting lever of motor shaft 5, two and jointly forms.The horizontal connecting lever of motor shaft 7 drive motor axle 5, by connecting rod 6 interlock to the horizontal connecting lever 4 of bearing, drive that bearing 8 lock is dynamic to be rotated.As shown in Figure 2, A position is top moving contact swing arm 9 bearing horizontal connecting lever 4 place initial position when closing position.During sub-switching operation, the horizontal connecting lever of motor shaft 5 is rotated by upper downward 180 ° of separating brakes counterclockwise, promoting the horizontal connecting lever 4 of bearing axle by connecting rod 6 rotates to B position, drive central rotating insulated son through alternate link gear, moving contact swing arm 9 is made to rotate to 75 ° of separating brake subtended angles, under this angle, between moving contact and fixed contact, between the offside moving contact of adjacent moving contact swing arm 9, there is safe separating brake insulation distance.The composition component of described lock driving mechanism is horizontal moving part; therefore the fixed cross beam 1 of each electricity mutually can be designed to the supporting construction closed at least top and both sides; protection lock driving mechanism is not by the such environmental effects such as dust pollution, acid-rain corrosion; especially in ice and snow sky, sleet, rain and snow mixed bad weather; also can ensure reliable switch motion, functional reliability improves.The three-phase ganged mechanism coordinated with this lock driving mechanism is the parallel hinges quadric chain connected between the rotating insulated son of three-phase, each mutually rotating insulated son is all fixed with a fork 10, described fork 10 is formed for symmetrical centre extends with its rotating insulated sub-axis of rotation, and between two adjacent forks, hinged two interlock connecting rods 11 form described parallel hinges quadric chain.The rotating insulated son of central authorities drives the dynamic rotation of both sides moving contact swing arm 9 synchronous gate through link gear.
