5 results about "Rotary converter" patented technology

A rotary converter is a type of electrical machine which acts as a mechanical rectifier, inverter or frequency converter. Rotary converters were used to convert alternating current (AC) to direct current (DC), or DC to AC power, before the advent of chemical or solid state power rectification and inverting. They were commonly used to provide DC power for commercial, industrial and railway electrification from an AC power source.

A screw pump well electric heating current collector converter

PendingCN122393687AConvertersBrush
The application discloses a kind of screw pump well electric heating current collection converter, including upper rotary converter and spring leg structure located below rotary converter;Rotary converter inside integrated carbon brush slip ring, carbon brush slip ring is connected with the cable of current collector by slip ring terminal post to realize the column rotation of screw pump and is connected to power supply;Spring leg structure is integrated with spring and spring rod to prevent upper rotary converter from shaking.The current collection converter of the application is used to solve the problems of difficult wellbore lifting, complex ground driving equipment and other problems in screw pump well, by installing a set of current collection converter on the upper part of screw pump driving head, cooperating with hollow sucker rod for downhole electric heating, to improve the temperature of crude oil in wellbore, reduce the viscosity of crude oil, so as to ensure normal and stable production of screw pump well.
