The invention discloses an energy-saving adiabatic temperature rise testing machine, which comprises an outer case, wherein a first heat preservation layer, a second heat preservation layer and an inner case are sequentially arranged in the outer case; a second groove is formed in one side of the lower end between the outer case and the inner case, and a first groove is formed in the middle part of the bottom end between the outer case and the inner case; a temperature sensor is movably mounted in the first groove; a temperature detector is movably mounted in the second groove; thermometers are movably mounted on two sides of the upper end of the middle part of the inner wall of the inner case by means of mounting bases; castors are fixedly mounted at four corners of the bottom end of theouter portion of the outer case; bearing pedestals are fixedly mounted on the two sides of the upper end of the outer portion of the outer case; a control box is fixedly mounted on one side of the lower end of the outer case; electric push rods are movably mounted in the bearing pedestals by means of rotating shafts correspondingly; and driven wheels are movably mounted at the ends, away from thecontrol box, of the electric push rods by means of couplers. The energy-saving adiabatic temperature rise testing machine is convenient for energy conservation, heat insulation and heat preservation.
Description
technical field [0001] The invention relates to the field of temperature rise testing machines, in particular to an energy-saving adiabatic temperature rise testing machine. Background technique [0002] The temperature rise test is a type test; the traditional temperature rise test assesses the average temperature rise of the winding (measured by the resistance method) and the temperature rise of the oil top layer. If the measured values of these two temperature rises do not exceed the allowable temperature rise limit specified in the standard, Then, the transformer is considered to have passed the type test of the temperature rise test, but with the increase of the voltage level of the transformer, the reduction of the loss of the large-capacity transformer, the appearance of the optical fiber temperature measuring device, the gas chromatography analysis technology in oil and the With the development of liquid chromatography analysis technology, the content of one of the...
