Cable and wireless integral nuclear phase instrument

The utility model relates to a detection device of a transmission and distribution power grid power transmission line, in particular to a cable and wireless integral nuclear phase instrument which is used for approving the phase of high- and low-voltage power lines in transmission and distribution power grid construction, repairing and maintenance. The instrument comprises a cable phase fixing instrument, a wireless phase fixing instrument, a power supply, a double-cutter double-position working mode switch, a single-cutter double-position testing method selection switch, four working status indicator lamp, i.e. a single-station test indicator lamp, a double-station test indicator lamp, a cable test indicator lamp and a wireless test indicator lamp and two relays; the windings of the relays are respectively connected with both ends of the double-station test indicator lamp and both ends of the wireless test indicator lamp; the two relays are respectively connected or disconnected by adjusting the working mode switch and the testing method selection switch so as to realize the selection of the working mode. The cable and wireless integral nuclear phase instrument has the advantages of simple structure, safe and reliable work, satisfaction to technical requirements, convenient operation, less equipment investment and lower production cost.
