Problems solved by technology
However, the resistance wire type explosion-proof electric heating tube has a life span of only about one year, and its life span is short, and once it is damaged, it takes about 3 to 12 hours to replace it, which takes a long time to replace.
Although it can save energy by about 10% to 25% compared with the traditional way of heating with liquefied petroleum gas or firewood in the form of a boiler, it takes more than 180 minutes to raise the temperature to 100°C, which is slow

The invention provides a 1140V ultrasonic frequency induction heater which is long in service life, rapid in replacement and warming and energy-saving, and aims to heat liquid such as crude oil, heavy oil, light oil and carbon dioxide in an oil field. The 1140V ultrasonic frequency induction heater is externally connected with a 1140V three-phase supply, and comprises a 1140V heating controller, an excitation coil and a temperature sensor, wherein the 1140V heating controller is electrically connected with the 1140V three-phase supply; the excitation coil is electrically connected with the heating controller and used for heating the oil pipeline; and the temperature sensor is used for detecting the temperature of the oil pipeline and transmitting the actually measured temperature to the heating controller.
Description
technical field [0001] The invention relates to a heater, in particular to a 1140V supersonic frequency induction heater. Background technique [0002] As we all know, the high voltage of oilfield electricity in my country is 6kV and the low voltage is 1140V, which is different from the industrial and agricultural electricity with high voltage of 10kV and low voltage of 380V. 1140V is a special voltage level used in oil fields that is different from other places. Therefore, in the industry that uses voltage 1140V for heating, the design of its heating equipment, etc. are also different. For example, although domestic electromagnetic heating methods such as household induction cookers are widely used in household heating equipment, they cannot be applied to 1140V oil field electricity because they only have 220V voltage, low voltage level, small penetration, and low efficiency. . And because it does not possess explosion-proof measures, it cannot be installed on oil pipeli...
