Abstract
The utility model relates to a frequency conversion transmission rectifying transformer which pertains to the field of transformer technology. The utility model is provided with an oil tank, a radiator, three-pole core (1) and a three phase pan winding, the main structural character is that a grounding shield (3) is arranged between a primary high voltage winding (2) and a next low voltafe winding (4) of every phase of pie winding. The utility model is characterized in high safety and reliability, low cost, long service life; which facilitates manufacturing of high capacity, low weight, large transformers; the utility model can be widely applied, and can be equipped with frequency conversion rectifying equipments of steel rolling, smelting, cement producing, wind power pump load, etc.
Description
Technical field
The utility model belongs to the transformer technology field.
Background technology
At present, external existing Frequency Drive rectifier transformer, the loss height do not have earth shield between high-voltage coil and low-voltage coil, and single-machine capacity is less.Domestic none family still produces this type of transformer, relies on import to solve fully, costs an arm and a leg.
Summary of the invention
The purpose of this utility model provides a kind of Frequency Drive rectifier transformer, its security reliability height, and long service life, big, the lightweight high-power transformer of the capacity of can making, purposes is wide.Can be supporting with the Frequency Drive rectification power consumption equipment of iron and steel steel rolling, smelting, cement manufacturing, the load of air pump class etc.
Main technical schemes of the present utility model is: a kind of Frequency Drive rectifier transformer, mainly comprise fuel tank, radiator, three post core type iron cores and three-phase disc coil thereof, be with low-voltage coil, high-tension coil on each iron core column, it is characterized in that being provided with earth shield between the elementary high-tension coil of every phase disc coil and the secondary low-voltage coil.
Above-mentioned earth shield is preferably and is copper coin earth shield, also can be aluminium sheet earth shield etc.
Above-mentioned low-voltage coil is good to adopt first and last head deriving structure arranged side by side.Also can adopt other pin configurations.
Because there is harmonic component in commutating circuit, the close value of the magnetic of iron is lower, in order to improve valve side output waveform, reduce no-load loss, improve the efficient of transformer, reduce the vibration and the noise of transformer, three above-mentioned post core type iron cores are preferably the iron core of full Dou seam atresia binding-type structure.Magnetic unshakable in one's determination is close to be got than low value to well.
In above-mentioned oil-filled transformer, be preferably in inner wall of oil tank and install electric screen additional, electric screen is connected and ground connection with fuel tank.To reduce stray loss, avoid local overheating.Electric screen with on the inner wall of oil tank that is laid in for good.Can be aluminium sheet electric screen or copper coin electric screen etc.Fuel tank case lid and folder are made as good with magnetic conduction steel plate not.
Characteristics of the present utility model are: can reach goal of the invention, be provided with earth shield between elementary high-tension coil and the secondary low-voltage coil, can eliminate the various high frequency overvoltage of net side influences valve side rectifying component, prevent that net side high frequency lightning surge is to the influence of valve side and prevent the generation of valve side higher harmonic current, prevent partial discharge, improved fail safe and the functional reliability and the useful life of transformer greatly.Can guarantee transformer long-term safety reliability service.Adopt other Rational structure in addition, can effective uniform end Electric Field Distribution, reduce the consume of transformer greatly, improve the efficient of transformer, save electric energy, increase the service life, the utlity model has that security reliability height, low, the economize on electricity of consume, efficient height, cost are low, the characteristics of long service life so can make.Simultaneously, can make big, the lightweight transformer of capacity.And purposes is wide, can be supporting with the Frequency Drive rectification power consumption equipment of iron and steel steel rolling, smelting, cement manufacturing, blower fan load of the pumps etc., can be used as two kinds of uses of AC-AC frequency conversion drive rectifier transformer and ac-dc-ac inverter drive rectifier transformer.
Be described further below in conjunction with embodiment, but not as to qualification of the present utility model.
