Description
Technical field
The present invention relates to the transformer device in a kind of oil well logging instrument, transformer unit is more particularly related to
Fixed structure.The invention further relates to assemble the method for transformer device.
Background technology
Transformer is the device for changing alternating voltage using the principle of electromagnetic induction, and main member is primary coil, secondary
Level coil and iron core(Magnetic core).Major function has:Voltage transformation, current transformation, impedance conversion, isolation, voltage stabilizing(Magnetic saturation transformation
Device)Deng.
Transformer can be divided into, according to use,:Distribution transformer, power transformer, full-sealed transformer, combined transformer,
Dry-type transformer, oil-filled transformer, single-phase transformer, furnace transformer, rectifier transformer etc..
The most basic form of transformer, including two groups of coils for being wound with wire, and each other inductively to couple together.
When certain alternating current(With a certain given frequency)Flow when one of which coil, will be induced with phase in another group of coil
The alternating voltage of same frequency, and the voltage swing sensed depends on the magnetic-coupled degree of two coils.
Most transformer has fixed iron core, thereon around once with secondary coil.Due to the height of iron material
Magnetic conductivity, most of magnetic flux of transformer is confined in iron core, therefore, two groups of coils can thereby obtain suitable high level it
Magnetic coupling.In some transformers, closely combined between coil and both iron cores, its once with the ratio of secondary voltage almost with
The coil ratio of the two is identical.Therefore, the turn ratio of transformer, the reference that may generally serve as transformer boost or step-down refers to
Mark.Due to the function of this boosting and step-down so that transformer turns into one of modern power industry system important adjunct, lifting
Transmission voltage cause it is long-distance transmit electric power more economical, as step-down transformer, it causes more diversification in terms of power operation.
It let us say that, without transformer, modern industry is unable to reach the present situation developed at present.
Transformer building block includes transformer body part(Iron core, winding, insulating component, lead), transformer oil, change
Depressor fuel tank and cooling device, regulator, protection device(Dehydrating breather, pressure-relief vent, gas relay, oil conservater and thermometric
Device etc.)And outlet casing tube.Wherein, the core material that transformer is used is to add element silicon in iron plate to reduce leading for steel disc
Electrically, increase resistivity, it can reduce vortex, reduce its loss.The steel disc for commonly referred to as having added silicon is silicon steel sheet, transformer
Quality used by the quality of silicon steel sheet have very big relation.
The main power supply used in logger is substantially DC linear voltage-stabilizing.Main electricity is by ground
The 220V of supply or so alternating voltage, down-hole power mainly by input transformer, rectification circuit, filter circuit, mu balanced circuit,
Protection circuit is constituted.
Most of current power transformer is fixed by being arranged on the clamping plate at transformer two ends.And surveyed in oil
