A transformer is a device used to convert AC voltage, current, and impedance. There are many types of transformers in classification:
First of all, according to the cooling method, we can be divided into dry type transformer, self-cooling transformer, oil intrusion transformer, fluoride transformer, evaporation
Cool the transformer.
The second can be divided into open type transformer, Guanfeng type transformer and sealed type transformer according to the way of preventing moisture.
The third can be divided into a core type transformer, a blade core transformer, a C type core transformer, and a ferrite core according to the iron core or the coil structure.
Transformers, shell transformers, toroidal transformers, metal foil transformers.
The fourth can be divided into single-phase transformers, three-phase transformers, and multi-phase transformers according to the number of power phases.
Fifth, in terms of use, we can be divided into power transformers, voltage regulating transformers, audio transformers, intermediate frequency transformers, high frequency transformers, and pulses.
Rushing transformers and so on.
Here we focus on some special parameters of the power transformer, there will be work efficiency on the special parameters of the power transformer
, rated power, voltage ratio, no-load current, no-load loss, efficiency, insulation resistance and so on.
The audio transformer and the high-frequency transformer are not the same special parameters as the power transformer, they will have a frequency response and the same frequency http://
Band and some primary and secondary impedance ratios and other related parameters.
High Resistance Alloy is used to produce resistance elementof conductive material.Requirements including High mechanical strength, good corrosion resistance and oxidation resistance. Working temperature is usually at500 ℃. Commonly used with constantan chromium iron, iron chromium aluminum, nickel chromium, nickel, resistivity rho (20 ℃) is 1 Ω was/m or so. It is not used in the conduction of current, but with its high resistance to limit or control the current in the circuit, such as motor, potentiometer, standard resistors, potentiometers, slip line resistor resistance element and resistance line, etc.; For the using of high resistance in the pressure sensor,Temperature compensator and temperature measuring resistor of resistance element to creatte reflect strain, temperature, magnetic field and parameters; High resistance alloy can also be used as heating elements in the manufacture of the resistance heating equipment, could be applied in current, voltage regulating and the winding of control components.
