The utility model discloses a manual spring stored energy structure guarantees to break off rapidly and the switch -on, four corners through the base is equipped with two unsteady clamp plate device of bridge that touch for it is more accurate to cooperate, to have static contact board and its inboard all to be equipped with the centre gripping protruding for the centre gripping between the moving contact board for the less fault current that can effectively utilize in contact sheet separation improves contact pressure, has better electric power compensation effect, has greatly improved anti bearing force.
Description
Technical field
The utility model belongs to electric switch technical field, especially relates to a kind of four station oil-immersed load switchs.
Background technology
On-load switch be one can under normal circuit condition (also can regulation overlond running condition under) close, carry and drop-out current and regulation abnormal loop condition under (as short circuit), by the switching device of official hour loaded current.Traditional on-load switch is as one independently controller switching equipment.Be connected to by electrical network on transformer, construction of switch is too complicated, and energy storage position is more unstable, stability and reliability poor; But bulky, heavier-weight, affect by cable mechanical stress and installation and maintenance costly; Secondly, electric power compensation effect is poor, and anti-loading ability is more weak.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, a kind of four station oil-immersed load switchs are provided, its tool small in volume, good insulation preformance, do not affect by cable mechanical stress, feature that preferably electric power compensation effect, load resistant power are strong and reliable and stable.
In order to realize above-mentioned object, the technical scheme that the utility model adopts is: a kind of four station oil-immersed load switchs, comprise operating mechanism and electrical system; Described operating mechanism comprises handle and Handle axis, and described handle is connected to the end of Handle axis; Described electrical system comprises pedestal, two tactile bridge floats fixation device and rotating shaft; Described pedestal is provided with cover plate; Described two tactile bridge fixation device of floating is arranged on the corner of pedestal; Described two tactile bridge fixation device of floating comprises moving contact plate and fixed contact plate, and described fixed contact plate is arranged on pedestal; Described moving contact plate is fixed in rotating shaft; Described moving contact plate includes moving contact plate and lower moving contact plate; Fixed contact plate is clamped with between described upper moving contact plate and lower moving contact plate; The end of described handle is provided with rotor, and one end of described rotating shaft is provided with swivel mount, is provided with torsionspring between described rotor and swivel mount.
Described Handle axis is set with connector.
The end of described upper moving contact plate is connected to the end of lower contact plate by set bolt.
Clamping projection is provided with inside described upper moving contact plate and lower moving contact plate.
After adopting said structure, the advantage that compared to the prior art the utility model has is: the utility model novel structure, adopts Manual spring energy storing structure, guarantees that load can disconnect rapidly and connect; The corner of pedestal is provided with two tactile bridge to float fixation device, makes the cooperation of dynamic and static contact plate more accurate, stable and reliable; And fixed contact plate is clamped with between upper moving contact plate and lower moving contact plate, and inside it, be provided with clamping projection, the less fault current that can effectively utilize in contact plate gap is made to improve contact pressure under failure condition, not easily affect by cable mechanical stress, there is good electric power compensation effect, drastically increase anti-loading ability.
