The invention relates to the technical field of transformer detection devices, and discloses a transformer iron core damage detection device. The transformer iron core damage detection device comprises a cylinder, and is characterized in that a curled spring piece is placed at the bottom end in the cylinder, a compression spring is fixedly connected to the upper portion of the curled spring piece,the upper end of the compression spring is fixedly connected with an impact ball, a movable plate is hinged to the left side wall of the cylinder, a supporting plate is arranged below the movable plate, a pull rod is fixedly connected to the left side surface of the supporting plate, a fixed plate is fixedly connected to the left side of the cylinder, a second metal sheet and a first metal sheetare sequentially connected to the left end face of the fixed plate from right to left, and the first metal sheet is hinged to the pull rod. According to the transformer iron core damage detection device, the pull rod is driven to move leftwards through different bending degrees of the first metal sheet and the second metal sheet after being heated, the movable plate is driven to rotate clockwise,then the curled spring piece loses support and expands, and the impact ball above the compression spring can irregularly impact in the cylinder to give out a warning sound.
Description
technical field [0001] The invention relates to the technical field of transformer detection devices, in particular to a transformer core damage detection device. Background technique [0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. It is mainly composed of an iron core and a coil. The coil has two or more windings. The winding connected to the power supply is called the primary coil, and the remaining windings are called the secondary coil. Among them, the transformer iron core mainly plays the role of magnetic conduction and skeleton. As the magnetic conduction part in the transformer, it is in a constantly changing electromagnetic field. The magnetization and magnetic induction of the iron core are also constantly changing. With the iron core, the primary and secondary The coil can have better mutual inductance coupling. [0003] The iron core of the transformer often encounters various faults during the wo...
