Background technology
In the middle part of extra-high-voltage alternating current transformer high-voltage, whether outlet is positioned at the center of fuel tank high pressure flange dish, device body is to the distance of inner wall of oil tank, very large on high-voltage lifting seat outgoing line device installation impact, its position and dimensional accuracy thus the insulator at impact to voltage conduit connection plate place are to the distance of outgoing line device voltage equalizing ball, when device body falls into fuel tank, in the middle part of high pressure, the centre deviation of outlet and fuel tank high pressure flange dish controls very crucial, the method that industry is taked usually is that box chi and level gauge are measured, or by " ten " word location, find Liang Ge center accurately and whether overlap.The method is not only lost time, and it is inaccurate to measure numerical value, thus when causing general assembly, high-voltage lifting seat outgoing line device is installed not smooth.
Summary of the invention
First the present invention discloses outlet positioner in the middle part of a kind of extra-high voltage transformer high pressure, and openly utilizes this device to carry out the localization method of outlet in the middle part of extra-high voltage transformer high pressure.
The adjusting rod that positioner of the present invention comprises locating flange dish and also coordinates with it through locating flange center hole, adjusting rod is provided with square ring survey mass; Locating flange dish has the one group of high pressure flange dish installing hole arranged along its circumference.
Positioner disclosed in this invention, can be positioned by locating flange dish and adjusting rod subtending ring survey mass, and further the location of the square ring of transformer body is played to the effect of benchmark thus, thus ensure the accuracy of square ring position when device body is installed, the final precision ensureing the installation of high-voltage lifting seat outgoing line device.
In such scheme, for guaranteeing the stability of square ring survey mass position after positioning, the central hole of locating flange dish is fixed with coaxial setscrew nut, and center-hole diameter is greater than adjusting rod diameter, and adjusting rod and setscrew nut spin.
In addition, locating flange dish is provided with suspension ring so that install.Locating flange dish comprises its core, outer shroud with high pressure flange dish installing hole, and connected by least three reinforcements between the two, suspension ring can be arranged on reinforcement.
Outlet localization method in the middle part of extra-high voltage transformer high pressure of the present invention, comprise above-mentioned outlet positioner, namely this positioner comprises locating flange dish and passes locating flange center hole and the adjusting rod coordinated with it, adjusting rod is provided with square ring survey mass; Locating flange dish has the one group of high pressure flange dish installing hole arranged along its circumference, and installing hole is corresponding with the hole site on high pressure flange dish at least partially; During installation, by locating flange dish and high pressure flange dish fastening; Adjusting rod is made to pass centre bore on locating flange dish, and fix square ring survey mass to the distance of fuel tank outer wall in the inner of adjusting rod according to the position of square ring on drawing and square ring, make the interior edge of square ring survey mass and high-tension coil lift one's head the position consistency locating square ring outer; Transformer body is fallen, with the determined position of square ring survey mass for benchmark, locates after square ring is alignd with it; Thus after ensureing that position and the device body of square ring put in place, dismounting positioning tool.
In the above-mentioned methods, determine that whether square ring is consistent with the position of square ring locating piece for ease of range estimation, the external diameter of square ring survey mass can be adopted to equal the external diameter of square ring.
In addition, for convenience of installing, and make parts try one's best under standard, the maximum spacing of the quantity in the internal-and external diameter of locating flange dish, the distribution of periphery hole, hole, the size in hole, holes is preferably consistent with fuel tank high-voltage terminal flange.
The present invention sends out design and completes, and utilizes positioner of the present invention and method, solves the mode of manual measurement location in the past, can not only ensure the accuracy of device body and high-voltage lifting seat outlet position, can also improve installation rate, ensure operating efficiency.
