Description
Technical field
The utility model relates to a kind of underground foundation structure, especially relates to a kind of high-power transformer underground foundation, belongs to field of power.
Background technology
Transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core (magnetic core).The major function of transformer has: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing (magnetic saturation transformer) etc.Can be divided into by purposes: distribution transformer, power transformer, full-sealed transformer, combined transformer, dry-type transformer, oil-filled transformer, single-phase transformer, furnace transformer, rectifier transformer etc.Transformer is in electric equipment and radio-circuit, and transformer is commonly used for lifting voltage, matched impedance, safety isolation etc.In generator, no matter be that coil movement is passed through magnetic field or Movement in Magnetic Field by fixed coil, all can be in coil induced potential, these two kinds of situations, the value of magnetic flux is all constant, but has variation with the magnetic flux quantity of coil intersecting chain, this is the principle of mutual induction.Transformer is exactly that one utilizes undesirable mutual electromagnetic inductance to answer, voltage of transformation, the device of electric current and impedance.The citation form of transformer, comprises two groups of coils that are wound with wire, and claims to unify in inductance mode each other.Major product has: transformer series is (single-phase, three phase mains transformer, single-phase and 3-phase autotransformer, machine tool control transformer, starting compensator, energy-economic transformer, Scott Connection Transformer, three phase transformations are single-phase, single-phase change three-phase, the nonstandard transformers such as UPS transformer), (the input for frequency converter of reactor series, out put reactor, DC flat-wave reactor, connection in series-parallel reactor, filter reactor, air core reactor etc.), filter series (the special input filter of frequency converter, output filter, sine wave filter) product extensively uses electric power, metallurgical, weaving, machinery, wind-powered electricity generation, the industries such as iron and steel.In the time that an alternating current (having a certain given frequency) flows in one of them group coil, in another group coil, will induce the alternating voltage with same frequency, and the voltage swing of induction depends on the degree of two coil couplings and magnetic interlinkage.The coil that refers generally to connect AC power is referred to as primary winding; And be referred to as primary voltage across the voltage of this coil.Induced voltage at secondary coil may be greater than or less than primary voltage, is to be determined by the turn ratio between primary winding and secondary coil.Therefore, transformer is divided into and is boosted and two kinds of step-down transformers.
Most transformer all has fixing iron core, is wound with once the coil with secondary on it.Based on the high magnetic conductivity of iron material, most of magnetic flux is confined in iron core, and therefore, two groups of coils can obtain the magnetic coupling of suitable high level by this.In some transformers, coil and iron core are closely combined between the two, and it is once almost identical with the coil ratio of the two with the ratio of secondary voltage.Therefore, the turn ratio of transformer, generally can be used as that transformer boosts or the reference index of step-down.Because this boosts and the function of step-down, make transformer become the important adjunct of one of modern power industry system, promote transmission voltage make long-distance transmit electric power more economical, as for step-down transformer, it makes the diversification more of power operation aspect, can say so, there is no transformer, the real present situation that cannot reach development of industry.There is the volume of some transformers very large, if place transformer according to traditional mode directly contacting with ground, easily causing the type transformer to produce huge impression to ground even destroys, and the mobile inconvenience of transformer, cause the easy corrosion of transformer or impurity to enter into transformer simultaneously.
