In allusion to the problems existing in substations concerning the surlarge-side control area of service interruption and the long power failure time in the traditional"zero-voltage and zero-current"isolation mode of fault points,a portable multi-scene emergency remote switching device is developed.The device uses 375 MHz radio-frequency(RF)remote control technology,retractable connecting rod and multi-angle base,which realizes the switching operation of various components at various angles.The field test results show that such a device is available to shorten the troubleshooting time of nearly 2.5 h to 18 min with the lines of service interruption involved drop to 0,which can be applied in engineering.
