The invention relates to a grounding detection protection device for upgrading and reconstruction of a stock FTU (feeder terminal unit), which is arranged between an original stock pole-mounted circuit breaker and a feeder terminal unit FTU of a power grid line. The grounding detection protection device is provided with an input end which is electrically connected with the pole-mounted circuit breaker through a line, a first data communication end which is electrically connected with the pole-mounted circuit breaker, and a second data communication end which is electrically connected with the feeder terminal unit FTU. The grounding monitoring protection device judges a grounding fault of the power grid line according to the operation data and drives the pole-mounted circuit breaker to connect or disconnect the power grid line; the grounding detection protection device only needs to be electrically connected with the pole-mounted circuit breaker and the feeder terminal unit FTU through lines, so that the pole-
