Technical field

The invention belongs to measuring instrument technical fields, and in particular to a kind of vernier caliper with Aeroassisted system, this The characteristics of kind vernier caliper, can apply steady pressure by gas source when being measure traverse line size, when eliminating different personnel detection The different drawback of the result that the pressure of application is different, obtains.

Background technique

The internal circuit of transformer coil constitution equipment, it and extraneous power grid are connected directly, and are most important in transformer Component, so we are often compared to coil in " heart " of transformer.It should have enough dielectric strengths, mechanical strength, resistance to Hot property and good radiating condition, while also there is reasonable craftsmanship and economy.Transformer coil be by conducting wire and Insulating part composition.General high-power transformer all uses copper conductor, and generally there is round and rectangle in the section of conducting wire, capacity very little Transformer and part special transformer often use round conductor, and the biggish power transformer of capacity generally uses rectangular conductor (i.e. strip conductor), the insulation of conducting wire can be paint or insulating paper.

Transformer is at runtime, it is desirable that coil can be withstood in the case where voltage rating and rated current are used continuously for a long time The test of various overvoltage and overcurrent.Such as operation and thunder and lightning lead to overvoltage, mistake caused by the suddenly-applied short circuit in power grid Electric current and overvoltage and the electromagnetic force accordingly generated, and be unlikely to that insulation breakdown, hot-spot, deformation or destruction occurs. It should have enough dielectric strengths, mechanical strength, heat resistance and good radiating condition, while also have reasonable work Skill and economy.

Winding over the ground, between winding and winding, winding be major insulation to the insulation between lead etc..In order to guarantee craftsmanship And economy, the reduction main insulating structure of general transformer manufacturers all as far as possible, general major insulation is also with regard to tens millimeters.Usual coil Radial size Control tolerance is ± 1.5mm, and size Control needs very stringent.If radial overgauge when coil winding, such as+5mm is past 5mm is reduced toward will cause main insulating structure, major insulation nargin deficiency is will cause, needing to scrap coil or make to deposit in properties of product In hidden danger.Therefore, extremely important to the control that coil is radial, coil diameter is negative adjustable by increasing paper washer item, but coil Just, it just can not find the measure remedied.So the electromagnetic wire of coiling generally requires to be controlled by minus deviation.One If there is 10 conducting wires on line cake and around and conducting wire is radial having a size of+0.1mm, and 10 conducting wires will generate 1mm principal-employment, subsequent Coiling is easily overproof.

Therefore, extremely stringent to the radial deviation control needs of conducting wire during transformer production, usual producer is all It is measured with vernier caliper.It is found in practice, the pressure that different people acts on vernier caliper movable claw in measurement is different, The numerical value measured will be different.Pressure slightly changes, and test result may be different, also can not just judge that the radial size of conducting wire is Often there is very big dispute, the subsequent quality that not can guarantee product in practice in no qualification.
