Abstract
An automatically pole-changing oil-immersed silicon stack relates to the high-voltage power equipment, in particular to the technical field of devices changing positive and negative poles of the high-voltage power equipment, comprising an insulating cylinder connected between two flanges, a fixed shaft in the direction of the length of the cylinder fixedly connected in the cylinder, a plurality of insulating sleeves and silicon stack plates alternately sleeved outside of the fixed shaft, a rotating shaft parallel to the fixed shaft is arranged in the cylinder, a plurality of rotor angle switch on-off devices are fixedly connected on the rotating shaft, each rotor angle switch on-off device is alternately arranged with the silicon stack plates and adjacent rotor angle switch on-off devices have opposite on-off ways, and a group of oil cylinders are fixed in the cylinder, the outer ends of retractable rods of which are connected with one end of the rotating shaft. The invention has the characteristics of fast change, small size, and stable and in-place action, and is capable of achieving the ideal radiating effect by using the plate silicon stack structure.
Description
Technical field
The present invention relates to high voltage electric power equip ment, particularly the conversion equipment technical field of the positive-negative polarity of high voltage electric power equip ment.
Background technology
Defectives such as existing silicon stack is two of positive and negative plates, is placed on respectively on the rotatable supporting plate, reaches the purpose of position of exchange positive and negative electrode by machine driving, and this conversion regime makes the floor space of setting big, and it is unstable to exist the polar switching contact, not in place.Moreover existing silicon stack is substantially based on tubulose, and voltage is directly proportional with pipe range, and tubulose is subjected to the structure length influence, makes its withstand voltage level not enough, uses almost nil for the high pressure field.
Summary of the invention
The object of the invention is to design and a kind ofly can be applied to the automatic polarity switching oil immersion silicon stack high pressure field, stable performance.
The present invention includes and be connected two insulating cylinder body between the ring flange, connect the dead axle that is provided with along the cylindrical shell length direction at the cylindrical shell internal fixation, spacer sleeve is put some insulation spacers and silicon stack plate outside dead axle; In cylindrical shell, arrange the rotating shaft parallel with dead axle, fixedly connected some corner switch on and off devices in described rotating shaft, each corner switch on and off device and silicon stack plate are arranged at interval, the break-make mode of adjacent corner switch on and off device is opposite, and at cylindrical shell internal fixation one group oil cylinder, the expansion link outer end of described oil cylinder is connected with an end of described rotating shaft, by stretching of oil cylinder, rotating shaft is rotated, thereby the position that drives the corner switch on and off device on it change, and the positive-negative polarity of silicon stack is changed.
The present invention has Fast transforms, and volume is little, the characteristics that action is stablized, put in place, and the silicon stack structure adopts slice structure simultaneously, can reach desirable radiating effect.
In addition, the present invention is provided with radome outside oil cylinder.Purpose is to prevent to produce partial discharge, plays the effect of electric field shielding.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
As shown in Figure 1, insulating cylinder body 1 is connected between two ring flanges 2,3, connects the dead axle 4 that is provided with along cylindrical shell 1 length direction at cylindrical shell 1 internal fixation, and spacer sleeve is put some insulation spacers 5 and silicon stack plate 6 outside dead axle 4.
In cylindrical shell 1, also arrange the rotating shaft 7 parallel with dead axle 4, fixedly connected some corner switch on and off devices 8 in rotating shaft 7, each corner switch on and off device 8 and silicon stack plate 6 be layouts at interval, and the break-make mode of adjacent corner switch on and off device 8 is opposite.
Fix a group oil cylinder 10 by oil cylinder seat 9 in cylindrical shell 1, the expansion link outer end of oil cylinder 10 is connected with an end of rotating shaft 7.
Radome 11 is set outside oil cylinder 10.
