Abstract

The invention provides a vibration detecting device for an on-load tap-changer. The vibration detecting device comprises a vertical post fixed on the ground; a lever support is arranged on the vertical post; a lever is pivoted on the lever support; a probing pin is arranged on one side of one end of the lever; the probing pin is provided with a spring opposite to the other side of the lever; the other end of the spring is fixed on the vertical post; a vibration detector for converting vibration into an electric signal is arranged on the other side of the lever; the probing pin end of the lever serves as a power arm end, and the vibration detector end of the lever serves as a resisting arm end; and the vibrating detector is electrically connected with an alarming control module. The vibration detecting device can effectively monitor the running state of the on-load tap-changer and gives out an alarm once the on-load tap-changer is subjected to failure.

Description

Technical field [0001] The invention relates to the field of transformer monitoring equipment, in particular, a vibration detection device for an on-load tap changer. Background technique [0002] The tap changer of a power transformer is used to adjust the output voltage of the transformer. Because the voltages in the power grid are not exactly the same, in order to make the transformer output rated voltage no matter where the transformer is installed on the grid, multiple taps are set on the high-voltage winding of the transformer and the taps are connected to the tap changer. , Connect to the grid through a switch. In this way, the tap switch can be connected to different transformer winding taps to change the turns ratio of the transformer's high and low voltage windings, so as to achieve the purpose of adjusting the output voltage of the transformer. There are two types of taps, no-load adjustment and on-load adjustment. The former can only adjust the position of the tap ...
