The present invention relates to an optical interface power supply control device and method for intelligent substation test equipment. The optical interface power supply control device comprises an optical interface module, a power supply module, an MOS tube and an external CPU. The optical interface module monitors the presence or absence of an optical signal with a specific wavelength, receives data of optical signal with the specific wavelength, then converts the data into electrical signal data, and converts a local electric signal into an output of the optical signal with the specific wavelength. The power supply module provides stable and reliable power supply for normal operation of the optical interface module. The external CPU control the MOS tube to connect or disconnect the power supplies of a transmitting unit and a receiving unit power supply of the optical interface module. According to the present invention, as for test equipment having a plurality of interfaces, especially for battery-powered testing equipment having a plurality of interfaces, the optical interface power supply control device for the intelligent substation test equipment is capable of significantly reducing the power consumption and quantity of heat of the equipment, extending the operation time of the equipment and reducing the cost for heat treatment of the equipment, and is especially suitable for optical interface power supply control of the intelligent substation handheld test equipment.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to an optical interface power supply control device and method for intelligent substation test equipment. Background technique [0002] Smart substations are the development trend of smart grid substations.
