Abstract
The utility model provides a survey meter used for transformer winding wires, and belongs to the technical field measurement. The utility model is to solve the problem of the inaccurate measurement results of the prior transformer winding wires. In the technical proposal of the utility model, the survey meter comprises an air cylinder, a fixed ruler frame, a measuring ruler head, a grating ruler, a display and an air accumulator. The air cylinder is fixed on the fixed ruler frame. The lower end of the fixed ruler frame is provided with a fixed ruler head. The end of the piston of the air cylinder is provided with a measuring ruler head. The grating ruler consists of a movable ruler and a fixed ruler. The movable ruler is permanently connected with the measuring ruler head through a drawbar. The fixed ruler of the grating ruler is permanently connected with the fixed ruler frame. Grating ruler signals are output by the display. The survey meter can measure under the designed standard pressure, eliminates the measured deviation resulting from human factors, which measures accurately, and is highly repetitive, and highly precise with the display precision improved by one grade compared with the routine measurement method, thus avoiding the measuring errors resulting from visual errors. The survey meter is compact in structure, portable, and usable with small loss of air supply and long service life.
Description
Technical field
The utility model relates to a kind of measuring equipment, particularly is exclusively used in the measuring instrument of measuring transformer winding coil, belongs to the surveying instrument technical field.
Background technology
As everyone knows, the winding wire of transformer ' s type product generally by copper, aluminium wire as conductor, outside coated insulation material is made.The thermal value of high-power transformer in operational process can be very big, so such power transformer product will take into full account the cooling problem when design.Conventional method is to adopt oil cooling or air cooling way cooling, so will leave enough oil ducts or air channel in the transformer housing and between winding wire.Because winding wire is to be formed by copper, aluminum steel outsourcing insulation, the size of its physical dimension directly influences the size in oil duct, air channel, and and then influences the running quality of transformer.Therefore, the measurement order of accuarcy of the measurement of winding wire physical dimension, particularly combination line, transposition line is very important.Winding wire core rigidity is stronger, insulation has certain elasticity again, and also to leave the gap between line, the pressure that in measuring process, should keep 1MP according to industry requirement between dip stick and the measured object, and survey instruments such as the common slide calliper rule that adopt at present, milscale can't guarantee pressure conditions, the testing staff is firmly different in addition, and each the detection firmly also produces some difference inevitably, thereby causes the uncertainty of measured value.This present situation can influence the running quality of transformer on the one hand because of measuring error, also causes the objection of both sides of supply and demand to product quality on the other hand.
Summary of the invention
The utility model is used to solve the defective of above-mentioned prior art and the accurately stable measuring instrument that is used for the Transformer Winding line of a kind of may command pressure, measured value is provided.
The alleged problem of the utility model solves by the following technical programs:
A kind of measuring instrument that is used for the Transformer Winding line, comprise cylinder 6, scale frame 12 during it constitutes, survey chi head 11, grating chi, display instrument 8 and gas bomb 1, described cylinder and scale frame are fixed, scale frame bottom is provided with scale head 13, the cylinder piston end is provided with surveys chi head 11, and described grating chi is made up of adjustable rule and fixed ruler, and grating adjustable rule 9 is through pull bar 10 affixed survey chi heads, grating fixed ruler 7 affixed scale framves 12, grating chi signal export to and show not instrument.
Be connected with muffler 5 pipelines by draft tube 4 between the above-mentioned measuring instrument that is used for the Transformer Winding line, described gas bomb and cylinder, describedly advance, return line is provided with two-way air valve 3.
The above-mentioned measuring instrument that is used for the Transformer Winding line, described gas bomb exit is provided with tensimeter 2.
The utility model at existing Transformer Winding line measurement result instability, easily produce error the problem specialized designs a kind of measuring instrument that is used for the measuring transformer winding wire, this instrument uses pneumatic cylinder as the displacement gear train, piston is obtained the size value of measured object under controlled pressure conditions, this measured value is read by digital indicator.The utility model principal feature is as follows: 1. can measure under the pressure standard of designing requirement, solve the measured deviation that human factor forms, measure accurately stable, good reproducibility, precision height; 2. utilize electric signal control output measurement result, its display precision improves an order of magnitude, and can avoid the measuring error that caused by the collimation error; 3. can carry out the adjustment of continuous stepless pressure when being used for the member profile dimensional measurement, to satisfy measuring element different measuring pressure demand; 4. compact conformation, be easy to carry, easy to use, the source of the gas loss is little, cylinder and digital display instrument frequency of usage are 10
5More than, long service life.
Description of drawings
Fig. 1 is the utility model structural representation.
Number in the figure is expressed as follows: 1. gas bomb; 2. tensimeter; 3. two-way air valve; 4. draft tube; 5. muffler; 6. cylinder, 7. grating fixed ruler; 8. display instrument; 9. grating adjustable rule; 10. pull bar; 11. survey the chi head; 12. scale frame; 13. scale head.
Embodiment
Human factor causes inaccurate and difference the utility model in the measurement winding wire size in order to solve, and introduces this controlling element of pressure when measuring.It with cylinder piston as the displacement gear train, under the pressure that requires, obtain the size value of lead by piston, displacement with piston passes to grating chi (precision 0.001mm) then, the measured value of grating chi is read by digital indicator, and this instrument can solve fully because the measured deviation that factor caused.
Referring to Fig. 1, comprise cylinder 6, scale frame 12 during the utility model constitutes, survey chi head 11, grating chi, display instrument 8 and gas bomb 1, cylinder is fixed on the scale frame, scale frame bottom is provided with scale head 13, the cylinder piston end is provided with surveys chi head 11, and it is corresponding up and down with the two position of scale head to survey the chi head.Used grating chi is made up of adjustable rule and fixed ruler, and grating adjustable rule 9 can be moved up and down with surveying the chi head by pull bar 10 affixed survey chi heads, grating fixed ruler 7 affixed scale framves 12, and the optical grating ruler measurement signal is exported by display instrument.Provide source of the gas by gas bomb 1 to cylinder, be connected with muffler 5 pipelines by draft tube 4 between gas bomb and cylinder, advance, return line is provided with two-way air valve 3, the gas bomb exit is provided with tensimeter 2.
When the utility model is used for the measurement of Transformer Winding line, measured object is placed on the scale head, opens the gas bomb valve, pressure is adjusted to working pressure, and connect display instrument and grating chi power supply.After the display instrument zeroing, open two-way air valve, cylinder piston drives survey chi head and moves to the clamping measured object, surveys to drive 9 actions of grating adjustable rule in the chi head motion process, and measuring-signal is delivered to display instrument output by the grating chi.
