Abstract
The utility model discloses a rectifier transformer core which is mainly composed of a lower clamping piece, an upper clamping piece and an iron core which are connected, wherein the iron core is clamped between the lower clamping piece and the upper clamping piece, the lower clamping piece and the upper clamping piece are connected and fixed by a screw bolt pulling device, a seal sheet is furtherarranged between the lower clamping piece and the upper clamping piece, the iron core is a three-phase five-post core, and the framework of the three-phase five-post core is composed of an upper yoke, a lower yoke, three main posts and two side posts, which are connected with each other, and the main posts are installed between two side posts. The key of the utility model lies in replacing a paralleling reactor in a rectifier transformer with the five-post core, and octave frequency band high harmonic waves of three phases, which have the same phase position, can form a return circuit throughtwo side yokes without passing through an oil tank, the clamping pieces and other structure elements, thereby greatly reducing the additional wastage on the structure elements. In addition, the three-phase five-post core can provide a return circuit for zero-sequence magnetic flux which is generated through phase-splitting voltage regulation, and reduces current impact caused by regulating each stage of voltage, thereby improving the quality of output electric power.
Description
Technical field
The utility model belongs to the components and parts field of power equipment, specifically relates to a kind of rectifier transformer iron core.
Background technology
The skeleton of present rectifier transformer is made of iron core, simultaneously in order to guarantee the stability of rectifier, and the quality that improves the output electric energy, tends to install additional interphase reactor in rectifier transformer, the increase that has brought cost undoubtedly, and install constant.Simultaneously, the rectifier transformer of this type, the high order harmonic component of 3 frequencys multiplication that its three-phase phase is identical can only be passed through the loop that members such as mailbox, folder constitute, and has increased the supplementary load loss on these members greatly; Can not provide the loop for the zero sequence magnetic flux that the phase-splitting pressure regulation produces simultaneously, increase the rush of current that every accent one step voltage causes, reduce the quality of output electric energy, so need improve.
The utility model content
The purpose of this utility model is to address the above problem, and a kind of simple in structure, rectifier transformer iron core that can reduce the member supplementary load loss and improve the output quality of power supply is provided.
For reaching the foregoing invention purpose, the technical scheme that is adopted is: a kind of rectifier transformer iron core, mainly by lower clamping piece, upper clamping piece and iron core connect and compose, described iron core is held between lower clamping piece and the upper clamping piece, between lower clamping piece and the upper clamping piece by drawing screw device to be connected and fixed, also be provided with mounting between lower clamping piece and the upper clamping piece, wherein iron core is the three-phase five-limb iron core, the skeleton of described three-phase five-limb iron core is mainly by at two parallel yokes up and down in two ends up and down and place up and down that three principal posts and the two other posts between the yoke connect and compose, and described principal post is installed between two other posts.The seam construction of the yoke up and down in the described iron core, principal post, other post is tiltedly directly to stitch alternately.The bottom of described lower clamping piece also is provided with the insulation of pad pin, square taper washer and pad pin.The edge of described lower clamping piece and upper clamping piece is provided with other screw rod, and other screw rod is provided with the phenolic aldehyde paper tube.The described screw device that draws is mainly by drawing screw rod, packing ring, nut and lock washer to connect and compose, and draws wherein that the position between lower clamping piece and upper clamping piece is provided with the phenolic aldehyde paper tube equally on the screw rod.Described upper clamping piece is provided with the drawstring seal.On the described iron core ground strip is arranged.
It is the key point that replaces interphase reactor in the rectifier transformer that the utility model adopts the pentastyle iron core, the high order harmonic component of 3 frequencys multiplication that three-phase phase is identical can constitute the loop by two return yokes, constitute the loop and needn't pass through structural members such as fuel tank, folder, thereby greatly reduce the supplementary load loss on these structural members.In addition, the three-phase five-limb iron core can provide the loop for the zero sequence magnetic flux that the phase-splitting pressure regulation produces, and has reduced the rush of current that every accent one step voltage causes, thereby has improved the quality of output electric energy.
