Background technique
Large-scale high frequency transformer is generally equipped with fuel tank, which is the shell of oil tank of transformer, built-in iron core and winding And full of oil tank of transformer oil, it is immersed in iron core and winding in oil, oil tank of transformer oil plays insulation and heat spreading function.It is infused in fuel tank The place of oil can stick patch capping and seal hole, and patch capping is rubber material.In the prior art, it generallys use more large-scale Air-leakage test instrument oil tank of transformer is detected, sounded an alarm when discovery has an oil tank of transformer of oil leak, work Make personnel screened out again come, this mode the problem is that: 1, above-mentioned air-leakage test instrument is generally expensive, right Cost is too high for general small business;2, detection and screening integration operation be can not achieve, complicated procedure of processing.
Summary of the invention
The invention is intended to provide a kind of screening plant for high frequency transformer, to realize to the detection of oil tank of transformer and The integrated treatment of screening.
In order to achieve the above objectives, base case of the invention is as follows: for the screening plant of high frequency transformer, including machine Frame, testing agency, sorting mechanism and driving mechanism, the sorting mechanism include erecting bed, the erecting bed row of offering vertically The screening mouth of oil tank of transformer is put, the erecting bed laterally offers holding tank, and the holding tank is opposite with screening mouth, the receiving The supporting block for cooperating support oil tank of transformer, the supporting block one end and receiving far from screening mouth are slidably connected in slot Tension spring is connected between slot, the receiving trench bottom offers limit hole, slidably connects in the limit hole and carries out to supporting block The limited block of limit is connected with the first pressure spring between the limited block and erecting bed;
The testing agency includes leather cup, the extrusion being slidably connected on leather cup, the promotion being fixedly connected on leather cup Bar, detection pipeline of the connection on leather cup are communicated with air bag on the free end of the detection pipeline, cut with scissors in the middle part of the detection pipeline It connects on the rack, and detection pipeline is in horizontality under normal conditions;
The driving mechanism includes actuator and the interlocking bar that is hinged on actuator, and one end of the actuator is hinged on In rack, the other end of actuator is connected on limited block, when in a horizontal state in detection pipeline, the interlocking bar and air bag It offsets.
The principle of this programme is: oil tank of transformer fuel tank being put in supporting block and erecting bed and is fixed, by leather cup It is pushed at the patch capping of oil tank of transformer and is bonded and closely avoid oil leak, extrusion is acted on into patch closure surface, and By it to oil tank of transformer Inner extrusion, if patch capping fitting is not close, oil body will be leaked out, and oil body is after testing Pipeline flows in air bag, makes the detection pipeline weight penalty and disequilibrium close to one section of air bag and rotates down, air bag then leads to Part of overdriving pulls limited block to move downward the limit being detached to supporting block, and supporting block is detached under the action of tension spring to transformer The support of fuel tank, underproof oil tank of transformer are just automatically fallen into screening mouth.
The advantages of this programme, is: 1, by implementing this programme, it can be achieved that detection to oil tank of transformer air-tightness quality It is handled with the one of screening, realizes the automatic processing of screening;2, by the cooperating in the detection gentle capsule of pipeline, not The case where additional power source, effectively controls the movement of supporting block, screens out to reach to unqualified oil tank of transformer.
Preferred embodiment 1: as the improvement of basic scheme, one section of caliber for detecting pipeline close to leather cup is greater than close to air bag one The caliber of section is conducive to oil body in order to increasing oil body pressure and is quickly blown into air bag when oil body pipeline after testing.
Preferred embodiment 2: preferably 1 improvement further includes resetting-mechanism, and the resetting-mechanism includes connecting rod, institute It is hinged on the rack to state connecting rod middle part, the connecting rod two end is respectively articulated with the control-rod being connected to detect on pipeline and for pushing away The push rod of dynamic supporting block, the push rod include upper push-rod and the lower push-rod hinged with upper push-rod, the upper push-rod and lower push-rod It is connected with the second pressure spring between opposite face, needs to pull after completing to sift out unqualified oil tank of transformer by above-mentioned setting Detection pipeline moves up, and in order to back the powder in air bag in detection pipeline, makes to detect pipeline reset, in this process In, driving push rod moves down, and makes lower push-rod push support block reset under the action of the second pressure spring.
Preferred embodiment 3: preferably 2 improvement, the junction between the extrusion and leather cup are equipped with elastic layer, To avoid during extrusion moves reciprocatingly leather cup there is oil leakage phenomenon.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the present invention for the screening plant embodiment of high frequency transformer.
Fig. 2 is the structural schematic diagram of resetting-mechanism in the present invention.
Specific embodiment
Below by specific embodiment, the present invention is described in further detail:
