The invention discloses a distribution transformer tapping switch gear display device and method, wherein the tapping switch gear display device comprises a tapping switch, a sealing hole, a gear adjusting handle, a rainproof cap, a gear information conversion device, a signal line, a metering automatic terminal and a server, wherein the tapping switch is connected with the distribution transformer through the sealing hole, and the gear adjusting handle is connected to the tapping switch; the rainproof cap covers the tapping switch, the gear adjusting handle and the gear information conversiondevice; the gear information conversion device is used for converting the gear position adjusted by the gear adjusting handle into gear information in an electric signal mode; the signal line transmits the gear information in the form of an electric signal to the metering automatic terminal; the metering automatic terminal is used for converting the gear information in the form of an electric signal into gear information in the form of a digital signal, and transmitting the gear information in the form of a digital signal to the server; and the server stores and displays the gear informationin the form of a digital signal. By adoption of the device and the method, the workload of operation and maintenance personnel is reduced, and the power supply reliability is improved.
Description
technical field [0001] The present application relates to the technical field of operation and maintenance of distribution transformers, in particular to a display device and method for a tap changer position of a distribution transformer. Background technique [0002] Distribution transformer is a kind of power equipment that transmits electric energy. Its function is to convert AC energy of a certain level of voltage and current into AC energy of another level of voltage and current at the same frequency. Distribution transformer is a distribution transformer. One of the very important equipment in the power grid is an important part of the power system. The safe and stable operation of the distribution transformer is directly related to the safe and stable operation of the distribution network, which in turn is related to the power supply reliability of the distribution network. [0003] The tap changer of the distribution transformer is an important component of the dis...
