Detailed description of the invention

Implementing to be further described to this utility model below in conjunction with accompanying drawing, following example are illustrative, are not limited , it is impossible to limit protection domain of the present utility model with this.

A kind of reinforced electric power compensation capacitor with arcuation hot channel, as in figure 2 it is shown, include capacitor tubbiness shell 5, Central authorities of portion are longitudinally mounted with the capacitor element 6 of multiple parallel connection in the enclosure, and the outer wrap at capacitor element has one layer of insulating paper 7, between insulating paper and outer casing inner wall, it is filled with insulation paraffin 8, capacitor element connects wire 4 and electrode connecting piece by electrode 3 connect, and electrode connecting piece is fixed on the bottom surface of contact pin dish 2 by rivet, at the upper surface correspondence rivet upper shed of contact pin dish Being welded with electrode contact pin 1, at the upper cover 10 being arranged above capacitor of electrode contact pin, the upper surface at upper cover is fixed with socket end Son 9, innovative point of the present utility model is, bottom capacitor case, symmetrical with bottom centre, has two in the outside of insulating paper Bar arcuation cylindrical void 15, is respectively welded arcuation pipeline 13 straight up, the upper shed of arcuation pipeline and electricity on two arcuation cylindrical voids Shell of tank upper shed flushes, and on contact pin dish, the position of corresponding two arcuation pipeline upper sheds, is formed respectively with and arcuation cylindrical void shape The contact pin dish through hole 12 that shape is identical, the on the capacitor position of the upper corresponding two contact pin dish through holes of capping, be formed respectively with leading to contact pin dish The upper cover through hole 11 that hole shape is identical, after being fixed with female terminal on upper cover by electrode contact pin on contact pin dish, on capacitor Capping is fitted at capacitor tubbiness shell upper shed, now, constitutes two arcuation pipelines from bottom to top in capacitor entirety Through hole, the heat produced when the sidewall absorption capacitor of arcuation conduit through bore works, increase the heat-sinking capability of electric heater further, Meanwhile, in insulation paraffin, uniformly dispersing has silica dioxide granule 14, and silica dioxide granule is the insulator of electricity, compares simultaneously There is again higher heat conductivility, it is possible to preferably take on housing by the heat on capacitor element from the point of view of relatively paraffin, reduce electricity The operating temperature of container component, promotes the performance indications compensating capacitor.

In of the present utility model being embodied as, the radian central angle corresponding to arcuation cylindrical void of described outer casing bottom is at 100 degree-110 Between degree, the radian central angle that arcuation cylindrical void is corresponding is the biggest, and heat-sinking capability is the strongest, but radian central angle is excessive, side capacitors Integrated stress structure dies down, between experiment repeatedly determines that the radian central angle corresponding to arcuation cylindrical void is spent at 100 degree-110.

In of the present utility model being embodied as, the width of arcuation cylindrical void is between 2.0mm-2.5mm, and this width the most still fills Divide the overall dimension configuration considering capacitor, the most also take into account the technology difficulty implementing to weld arcuation pipeline on arcuation cylindrical void.

In of the present utility model being embodied as, described silica dioxide granule is specially diameter granule between 1.0mm-1.2mm, Owing to the proportion of silicon dioxide is more than paraffin, so the silica dioxide granule adding volume excessive in happy and harmonious paraffin will cause , there is situation pockety in particles sink, through repetition test, and diameter silicon dioxide between 1.0mm-1.2mm Can hold in grain technique, it is achieved being uniformly distributed of silica dioxide granule.

In of the present utility model being embodied as, add paraffin cumulative volume and the ratio adding silica dioxide granule cumulative volume be 1:0.85, This ratio both can guarantee that the formedness of heat conduction, can realize again integrally-built uniformity, insulating properties.

By contrast experiment, the compensation capacitor of application this utility model technology compensates than common in the case of comparable operating conditions The temperature of capacitor case improves 1.8 degree of-2.0 degree, is greatly improved the heat-sinking capability compensating capacitor.
