Embodiment

Isolating switch as depicted in figs. 1 and 2, it comprises insulator foot 1, power end binding post 2, the quiet edge of a knife 3, load wiring post 4, the static ground edge of a knife 5, four blade moving plate interlock conversion equipment 6, light-emitting diode 7, power end binding post 2 and the quiet edge of a knife 3 are fixedly installed on above the plate face of insulator foot 1, power end binding post 2 is electrically connected with the quiet edge of a knife 3 is corresponding one by one, four blade moving plate interlock conversion equipment 6 is arranged in the middle part of insulator foot 1, the static ground edge of a knife 5 and load wiring post 4 are fixedly installed on below the plate face of insulator foot 1, four blade moving plate interlock conversion equipment 6 is electrically connected with load wiring post 4 is corresponding one by one, and select one with the quiet edge of a knife 3 and the static ground edge of a knife 5 and be connected, also comprise anti-error switch 8, described anti-error switch 8 is made up of anti-error switch knob 9 and switch body, anti-error switch knob and switch body are in transmission connection, and with four blades link conversion equipment insulation operating grip 12 padlock or be separated, two wiring pins of described switch body side are electrically connected with No. 3 connecting grooves and No. 4 connecting grooves that are arranged on insulator foot side respectively, two wiring pins of switch body opposite side are electrically connected with No. 1 connecting groove and No. 2 connecting grooves that are arranged on insulator foot side respectively, automatic switch 10 (preferably) or the RCD of connecting with power end binding post 2 is provided with above the panel being positioned at described insulator foot 1, No. 1 described connecting groove is connected respectively by the control power interface of wire with automatic switch 10 or RCD with No. 2 connecting grooves.

The number of the described quiet edge of a knife 3 and the static ground edge of a knife 5 is 4, and correspondence is fixed on the both sides up and down of four blade moving plate interlock conversion equipment 6 respectively, described 4 the static ground edge of a knife 5 earths.

Described power end binding post 2 is divided into A binding post, B binding post, C binding post, N binding post, corresponding load wiring post 4 is divided into A` binding post, B` binding post, C` binding post, N` binding post, described A binding post, B binding post, is in series with Light-Emitting Diode 7 and divider resistance respectively between C binding post and N` binding post.

The edge correspondence of described insulator foot 1 is provided with installing hole 11, and the number of described installing hole 11 is 4.

Operation principle of the present utility model: when insulation operating grip 12 moves up to spacing, the four blade moving plate interlock of four blade moving plate interlock conversion equipment 6 goes to power-line terminal 2 side of top, after closed with four quiet edges of a knife 3, namely form four, downside load wiring post 4 to be communicated with four, upside power end binding post difference one_to_one corresponding, connect supply line; The operating grip 12 that insulate moves downward 180 ° to time spacing, and the four blade moving plate of four blade moving plate interlock conversion equipment 6 departs from power-line terminal 2, moves to four static ground edges of a knife 5 and closes formation safety ground.Anti-misoperation locking and unblock: 1, locking: isolating switch coordinates RCD or automatic switch 10 to connect to use.When needs switch on power, first automatic switch and RCD power supply are disconnected, then insulation operating grip 12 is moved upward closed after, then operate anti-error switch knob 9 and interlock with the operating grip 12 that insulate.Now, switch body internal switch is connected, then connects RCD power supply and make it combined floodgate power transmission; 2, unlocking: when needing interruption maintenance, first disconnecting RCD mains switch and cutting off power supply, more anti-error switch knob 9 is unlocked, and depart from insulation operating grip 12.As misoperation insulation operating grip 12, can not throw off because insulation operating grip 12 is locked, only have and anti-error switch knob 9 is moved downward unblock; Now, switch body internal switch disconnects, and is disconnected RCD power supply, has cut off main circuit.Because power terminal blade and earth terminal blade share one group of four cutting blade, effectively switching on earth wire can be prevented.

There are four small-sized binding posts isolating switch upper right side, and number is numbered 1 terminal, 2 terminals, 3 terminals, 4 terminals from top to bottom.After anti-error switch knob 9 is unblanked, 1 terminal, 2 terminals disconnect, and 3 terminals, 4 terminals are closed; After anti-error switch knob 9 and insulation operating grip 12 interlock and close, 1 terminal, 2 terminals are connected, and 3 terminals, 4 terminals disconnect.
