Energy-saving sleeve temperature rise test device

Abstract

The invention discloses an energy-saving sleeve temperature rise test device, which comprises a metal oil tank, a plurality of insulating spacing plates, an opening switch and a winding, and is characterized in that the plurality of insulating spacing plates are uniformly and vertically fixed on the metal oil tank, and the winding is wound on the plurality of insulating spacing plates; the opening switch is connected with the winding; the plurality of insulating spacing plates have the same structure and are long-strip-shaped plates, trapezoidal teeth are arranged on the long edges of one sides of the long-strip-shaped plates, the long edges of the other sides of the long-strip-shaped plates are vertically fixed on the outer wall of the metal oil tank, the winding is wound on the plurality of insulating spacing plates and embedded into the trapezoidal teeth of the insulating spacing plates, and the winding height of the winding covers the whole or partial height of the metal oil tank. And the trapezoidal tooth openings are wound by various wires with diameters smaller than those of various wires. The transformer oil is heated through a physical method; the insulating spacing plates are used for sectionally spacing heat of the outer wall of the metal oil tank, so that the winding is difficult to soften by high temperature of the outer surface of the metal oil tank; the insulation spacing board is suitable for a wire with a smaller diameter, so that the temperature monitoring work is continuously and accurately carried out.

Description

technical field [0001] The invention relates to a casing test tool, in particular to an energy-saving casing temperature rise test device. Background technique [0002] China is a big energy consumer, of which more than 74% comes from thermal power generation, that is, using coal and other combustible materials to generate electricity. In the face of the contradiction between energy shortage and huge demand, in addition to saving power consumption in daily life, it is also necessary to reduce power consumption in the process of upgrading equipment use, so as to maximize the utilization rate and efficiency of equipment, and through technical means To achieve the effect of reducing energy consumption. [0003] According to the requirements of the national standard GB / T4109: bushings with one or both ends immersed in oil or other liquid insulating media should be immersed in oil at ambient temperature, but for transformer bushings, the oil temperature should be kept higher tha...
