Abstract

The utility model belongs to a high-voltage rectifier, mainly solving the problem that magnetic leakage of a high-voltage rectifier for tar dust removing equipment is large and output power is lower than the needed power which is required. The utility model is characterized in that the utility model comprises an iron core, a primary coil, a secondary coil, and a commutation filtering circuit. Two pieces of column iron of the iron core are both provided with a primary coil. The primary coil is connected with an annular groove-shaped frame made of temperature resistance micro dielectric organic glass by a supportng lining. The secondary coil is arranged in the annular groove-shaped frame. The utility model which has the advantages of reduction of magnetic leakage, material saving, and improvement of real output power meets the requirement of tar dust removing equipment.

Description

Remove tar dirt equipment high-voltage rectifier

The utility model relates to a kind of high-voltage rectifying transformer, and industries such as particularly a kind of chemical fertilizer and coal gas are used removes high-voltage rectifying transformer in the tar dirt equipment.

The rectifier of generally acknowledging all is made up of iron core, primary coil, secondary coil, current rectifying and wave filtering circuit at present, determine the turn ratio of primary and secondary coil according to the height of requirement voltage, boost or the purpose of step-down to reach, and direct current output behind current rectifying and wave filtering circuit.The insulating material of wherein selecting for use mostly is cardboard, epoxy plate, fabric swatch and so on.Influenced by itself conducting medium, remove tar dirt equipment with the direct current extra-high pressure (during the rectifier of 40KV～150KV) in design, for preventing that voltage breakdown is except that increasing insulation thickness, also need strengthen high-tension coil over the ground, the gap of low-voltage coil, or primary and secondary coil is installed in respectively on two post iron of iron core.Its weak point one is to increase cost, waste material; The 2nd, cause leakage field too big, rectifier output voltage behind on-load is heavily decayed, power output does not reach except that the requirement of tar dirt equipment power demand, has had a strong impact on to remove tar dirt efficient.

The purpose of this utility model provides a kind of at above-mentioned weak point exactly and can satisfy except that the required high-voltage dc voltage of tar dirt equipment, can reach required power output again, and save materials such as steel, silicon steel sheet remove tar dirt equipment rectifier.

Technical solution of the present utility model is: a kind of tar dirt equipment high-voltage rectifier that removes, comprise iron core, primary coil, secondary coil and current rectifying and wave filtering circuit, and it is characterized in that: on two post iron of iron core, be equipped with primary coil.This primary coil is outer to connect an annular groove shape skeleton of being made by heatproof micro medium pmma material through a lining, is provided with secondary coil in the skeleton.

The post iron of the iron core described in the utility model technical solution and the ratio of yoke can be 1.8～2.3/2.7～3.5.

The utility model is owing to adopt heatproof micro medium polymethyl methacrylate as insulating material, and insulation property increase greatly, thereby has dwindled high pressure to low pressure, the high pressure distance between (iron core) over the ground.Press the designing requirement of 110KV transformer main insulation, high pressure is to iron core (yoke) 〉=90mm, every spaced apart 〉=70mm, and oil tank wall 〉=150mm, two coil-spans 〉=70mm, high pressure is to low pressure shield distance 〉=50mm, and the new spacing of this practicality only needs 25～35mm.Because the shortening of various spacings, primary and secondary coil all is wound on two post iron, magnetic circuit the best, thereby reduced leakage field, dwindled volume, saved material, reduce eddy current, reduced copper loss, iron loss, improved the real output of transformer, satisfied the requirement that removes tar dirt equipment, made it reach the desirable tar dirt effect removed.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the utility model circuit theory diagrams;

Fig. 2 is the utility model transformer sectional structure chart;

Fig. 3 is the utility model transformer longitudinal sectional structure chart.

The utility model is described in further detail below in conjunction with accompanying drawing: as Fig. 1～shown in Figure 3.Two primary coils 2 are wound on respectively on two post iron of iron core 1.Secondary coil 3 is wound in the annular groove shape skeleton 7, and skeleton 7 is made by heatproof micro medium pmma material.Fixedlyed connected by a lining 6 between skeleton 7 and the primary coil 2, its spacing is 30mm.Propping up lining 6 is also made by heatproof micro medium pmma material.The post iron and the dimension scale between the yoke of iron core 1 are 1.8～2.3/2.7～3.5.Rectifier bridge 4 and filter 5 are identical with rectifier bridge and filter in the existing rectifier.The utility model can rise to 0～150000V with 0～240V, 0～420V voltage, and power output is big, can satisfy the requirement that removes tar equipment fully.
