Abstract
The utility model relates to a capacitive type three phase common high voltage sleeve, which belongs to the technical field of insulator and which is used for solving the problem of compact conformation of the high voltage sleeve. The utility model comprises sleeve porcelain accessories, a capacitive core and a supporting brass pipe. Three-phase lead wires are arranged in the supporting brass pipe. Each phrase lead wire is packed with an insulating coat. The top end of the high voltage sleeve is provided with an oil tank which is filled with transformer oil. Three wiring small sleeves are mounted on the wall of the oil tank. Two ends of the wiring small sleeve are positioned in the oil tank wall and outside the oil tank wall. One end of the three wiring small sleeves in the oil tank is respectively connected with a phase lead wire in the supporting brass pipe. The structure can lead out the three-phase lead wire in the winding end of the star-connected graded insulation power transformer through a sleeve, then the utility model is connected with other electrical equipment, so the trouble of leading out the three sleeves respectively is avoided and the installation space is saved. The advantage of the utility model makes a non-excitation voltage regulation electric transformer realize the improvement of the on load voltage regulation mode in the site.
Description
Technical field
The utility model relates to a kind of electric power graded insulation Transformer Winding end draws with three-phase common high voltage sleeve pipe, belongs to the insulator technical field.
Background technology
Large-scale power transformer in the electric power conveying engineering is indispensable equipment.For the graded insulation non-excitation pressure adjustment large-scale power transformer in using, as desire to carry out the transformation of voltage regulating mode at neutral point series connection Loading voltage regulator, former transformer three phase winding ends can only be drawn respectively and are connected with voltage regulator, at this moment need to use a plurality of sleeve pipes, institute takes up space bigger, and is also quite difficult.In order to realize the transformation of this mode on the general transformer and don't to use outer surface structure to carry out big transformation (under most of situation to transformer, the reason that this transformation is arranged owing to sleeve pipe almost is impossible), at this moment just can not use a plurality of bigger single lines that take up space to draw the bushing of structure, thereby influence on-the-spot transformation power transformer.
Summary of the invention
The utility model is used to overcome three bushings of above-mentioned usefulness and draws the defective of three-phase high-voltage winding end leads and a kind of compact conformation is provided, can provides three phase windings the terminal condenser type three-phase common high voltage sleeve pipe that connects.
The technical scheme that addresses the above problem is:
A kind of condenser type three-phase common high voltage sleeve pipe, it comprises the sleeve pipe porcelain spare of general oil-impregnated paper insulation condenser-type terminal, capacitor core, support copper pipe, wherein, capacitor core is wrapped in and supports outside the copper pipe, sleeve pipe porcelain spare is enclosed within outside the capacitor core, its improvements are, be provided with three phase terminals in the support copper pipe of bushing, every phase terminal is surrounded by insulating coating outward, be provided with a fuel tank on the top of bushing, be full of transformer oil in the fuel tank, three wiring small casings are installed on the oil tank wall, their two ends lay respectively at oil tank wall in, outer both sides, the axis of three wiring small casings constitutes a plane, this plane and bushing axis normal, the end of three wiring small casings in fuel tank are connected with a phase terminal that is positioned at the support copper pipe respectively.
Above-mentioned condenser type three-phase common high voltage sleeve pipe, described fuel tank is cylindrical, three wiring small casings are the hexagonal angle degree along the oil tank wall circumference and distribute in the plane that its axis constituted.
Above-mentioned condenser type three-phase common high voltage sleeve pipe, in the described wiring small casing one is provided with bonding wire with fuel tank.
The utility model can be drawn three phase terminals of graded insulation Winding in Power Transformer end by a sleeve pipe, be connected with the three-phase Loading voltage regulator with same sleeve pipe, that has avoided adopting three sleeve pipes to draw respectively is loaded down with trivial details, can also reduce the bigger change of outer surface structure when former transformer undergone technological transformation simultaneously.Its compact conformation, take up room for a short time, less relatively occasion has special advantage to this characteristics in the locus, and it will make the original very connection of difficulty of High-Voltage Electrical Appliances be achieved.
