Embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Among Fig. 1, provide a kind of anti-oil the quick-fried amorphous alloy transformer of letting out in the present embodiment, comprise: the fuel tank 6 of transformer body 4 and transformer body 4 inside, it is characterized in that: draw two mozzles (upper and lower mozzle 2,3) on described fuel tank 6 sidewalls with its perforation, this mozzle passes the sidewall of transformer body 4, be connected with the oil storage cavity 1 of an inflatable distortion that is arranged on transformer body 4 outsides and communicate with it, the inwall of this oil storage cavity 1 is provided with some places wrinkled line 5.
Wherein, the above-mentioned mozzle of mentioning adopts bigbore pipe, and pipe diameter is φ 100mm in the present embodiment.The transformer of different volumes size, caliber are also different.The concrete size of caliber presses the volume of transformer size and explosion energy calculating determines that the capacity of transformer is big more, and bore is also big more.
Described oil storage cavity is subjected to the influence of internal force can be to the both sides dilatancy, so adopt the ductility of material to get well.Adopt Cu alloy material in the present embodiment, copper alloy possesses the good ductility that adheres to specification and is beneficial to its distortion energy-absorbing, simultaneously, also can come the instead of copper alloy with the good material of other ductility.The chamber wall thickness of oil storage cavity calculates definite according to the quick-fried energy value of letting out of transformer.If the capacity of transformer body is bigger, can increase the number or the volume size of oil storage cavity.Present embodiment has adopted 2 cavitys, is separately positioned on transformer body both sides.
Wrinkled line 5 above-mentioned is to push the vestige that forms by the workmen with the pressing and forming cutter tool on cavity inner wall, is the relative intensity weak spot, and its size shape and position pre-determine by designing and calculating.When the cavity internal pressure was above standard, cavity at first began distortion at the wrinkled line place, thereby the shape that the guidance cavity body deformability becomes to estimate is controlled its deformed shape.
Described cavity side inwall is provided with some horizontally disposed wrinkled lines, and this wrinkled line is a deformation intensity discount line 51, arranges on vertical direction is even, is arranged in the oil storage cavity side inwall by transformer body that demifacet far away.51 minimizings of this deformation intensity discount line deformation intensity is used, promptly working as transformer breaks down, the oil storage cavity begins dilatancy, guarantee under the fault pressure-driven by design appointed positions and approach bending distortion, reach the purpose of energy-absorbing buffering, increase considerably the capacity of deformable cavity simultaneously and reduce inner internal force, reduce the quick-fried probability of letting out.
During use, when tank internal pressure reaches quick-fried when letting out critical point, this oil storage cavity can be by the wrinkled line on its side inner walls, press shape powerful deformation under the fault pressure-driven of design setting, as shown in Figure 2, cavity expands at leisure to both sides, and outer one side is expanded particularly evident.In the process of distortion, wrinkled line can absorb the quick-fried energy of letting out, simultaneously, the direction of distortion is to make the volume of this device amplify tens times, reduce the pressure in the oil tank of transformer, play the effect of energy-absorbing increase-volume step-down, thereby reach purpose from draining to the external world that avoid transformer to blast and spray.
