Abstract

The utility model relates to a high-tension transformer used for a downhole oil instrument. The high-tension transformer comprises an iron core, a framework and a coil winding. The high-tension transformer is characterized in that the iron core is a microcrystalline iron core and the framework is a polytetrafluoroethylene framework. The high-tension transformer solves the technical problems of big temperature drift, low efficiency and high cost when a transformer in a background art is used in the environment of high temperature. The operating ambient temperature of the iron core ranges from 25 to 180 DEG C, under the condition of the same power, the transformer is smaller in power consumption and heat dissipation of the transformer can become better, and the high-tension transformer is small in volume, big in power, and convenient to install within a narrow space under oilfield downhole.

Description

High-tension transformer

Technical field

The utility model relates to a kind of transformer, is specifically related to the high-tension transformer that a kind of down-hole oil instrument uses.

Background technology

In the manufacturing process of various oil exploration loggers; The high-tension transformer that needs various special purposes; As the important components and parts of whole instrument, to the output voltage of transformer, operating frequency, withstand voltage etc. having higher requirements, the temperature when existing transformer uses under hot environment is floated and greatly maybe can not be used; And manufacturing cost is high, influences the use of petroleum exploration instrument.

Summary of the invention

The purpose of the utility model is to provide a kind of high-tension transformer, and the temperature that has solved when under hot environment, using in the background technology is floated greatly the technical problem that efficient is low, cost is high.

The technical solution of the utility model is:

A kind of high-tension transformer,

Comprise iron core, skeleton and coil windings, be wound with line bag 3 on the said skeleton 2, be inserted with iron core 1 in said skeleton 2 windows, it is characterized in that iron core is the crystallite iron core, skeleton is the polytetrafluoroethylene skeleton.

The utility model has the advantages that:

1. the advantage of crystallite iron core is that volume is little, efficient is high; The advantage of polytetrafluoroethylene skeleton is heatproof greater than 250 degree and insulate finely, and what general skeleton was used is the epoxy fabric swatch.The transformer operating ambient temperature is between-25 ℃～180 ℃, and this high-tension transformer is tested withstand voltage reaching more than 10000 volts, and the transformer heat radiation is relatively good, and volume is little, power is big, is convenient in the narrow space of down-hole, oil field, install.

The utility model under hot environment, use temperature float little, volume is little, the big efficient of power is high, and working stability, the power transformer that anti-interference cost is low.
