The both sides of iron core wrap, and have been respectively fixedly connected with clamping bar on connecting seat, and the top of left clamping plate and right clamping plate is welded with vertical
Bar, vertical rod and clamping bar are hinged, therefore clamping bar forms a lever construction by fulcrum of vertical rod, when clamping bar top by
Effect to power is rotated with right side to the left respectively, and the bottom of clamping bar can be caused to move in the opposite direction respectively, both may be used
So that to pushing away in the middle part of iron core, and then left clamping plate and right clamping plate are clamped into iron core.Stretched between the top of two clamping bars provided with rhombus
Contracting plate, the lower section of rhombus expansion plate are provided with siphunculus, and siphunculus bottom is communicated with oil pocket, is equipped with oil pocket very sensitive to temperature change
Heat sensitive pressure oil, when iron core is delivered to oil pocket by induction sphere because of heat caused by work along heat transfer bar, the temperature-sensitive pressure in oil pocket
Power oil expanded by heating, rhombus expansion plate can be entered along siphunculus, and be extruded to both sides, cause rhombus expansion plate gradually to become so that flat
It is flat, therefore the both side ends of rhombus expansion plate generate both sides displacement to the left and right respectively, and then two clamping bars have been extruded respectively
Top so that iron core the more is pressed the more tight by left clamping plate and right clamping plate, realize using transformer work caused by temperature,
Iron core is clamped so that iron core more fastens, and suppresses gap or the air gap increase of iron core, reduces transformer loss, increase
Add the safety coefficient of transformer in electronic device.
Preferred scheme one：As the further optimization to base case, oil pocket is spherical glass oil pocket, is easy to observation oil
Oily state, is easy to staff to be monitored in chamber.
Preferred scheme two：As the further optimization to base case, the heat transfer bar of oil pocket outer surface radially distributes,
So that the heat that the surface of oil pocket receives is more uniform.
Preferred scheme three：As the further optimization to base case, left clamping plate and right clamping plate are that the ceramic of insulation is made
The left clamping plate and right clamping plate made, ceramic thermal insulation insulate again improves safety coefficient.
Preferred scheme four：As the further optimization to prioritization scheme one, a circle cavity is provided with the glass wall of oil pocket, it is empty
Water is housed in chamber, forms convex lens effect so that heat can more quickly pass to heat sensitive pressure oil.
