Abstract

The invention relates to the technical field of power transformers, and discloses a power transformer with a short-circuit alarm function, including a bottom plate, an oil tank is fixedly connected to the upper surface of the bottom plate, and two support rods are fixedly connected to the top of the oil tank. The top of the tank is fixedly connected with an oil conservator, one side of the fuel tank is fixedly connected with an alarm box, one side of the inner wall of the alarm box is fixedly connected with a second fixed shaft, one side of the second fixed shaft is movably connected with a rotating rod, One side of the bar is movably connected with a warning light. The invention can not only pull the cover plate by the pull rope to move the alarm light out of the alarm box, so that the device can timely alarm the staff after a short circuit occurs, which improves the safety of the device, and at the same time can reduce the temperature in the fuel tank through the cooling fins , so that the heat of the oil in the fuel tank can be dissipated, and the dust on the heat dissipation fins can also be cleaned by the scraper, so as to avoid excessive accumulation of dust on the heat dissipation fins and affect the heat dissipation efficiency.

Description

technical field [0001] The invention relates to the technical field of power transformers, in particular to a power transformer with a short-circuit alarm function. Background technique [0002] As we all know, a power transformer is a static electrical device that is used to change a certain value of AC voltage (current) into another or several voltages (current) with the same frequency. When alternating current is used, alternating magnetic flux is generated. The alternating magnetic flux induces alternating electromotive force in the secondary winding through the magnetic conduction of the iron core. The level of the secondary induced electromotive force is related to the number of turns of the primary and secondary windings Related, that is, the voltage is proportional to the number of turns. [0003] The power transformer will have a short circuit when it is in use. If it cannot be alarmed in time, it will have a great impact on people's use. Staff and on-site personn...
