（3）With circuit two（4）, circuit one（3）With circuit six（32）The other end be connected, circuit two（4）With another substation's phase
Connection；
6th step：Galvanized iron sheet is bright at semicircular anchor ear, anchor ear both sides it is bright go out mounting ear, make a call to two holes on mounting ear；
7th step：Galvanized steel bar is bright at semicircle, and with anchor ear（5）Mounting ear weld together；
8th step：Galvanized iron sheet is processed into sector, with anchor ear（5）And skeleton（6）Riveting, sprays caution slogan on one side（8）；
9th step：It steps on to electric pole one（3）Rice position, uses drift bolt（9）By two pieces of anchor ears（5）It is fixed together.
9. a kind of 10kV circuits dual power supply, which is handed in hand, gets in touch with the application method of structure, using any one described in claim 1-7
Item dual power supply gets in touch with hand in hand structure, it is characterised in that following steps：
In circuit normal operational condition, electric pole two（10）On disconnecting switch（17）With electric pole four（26）On disconnecting switch
（33）In unzipped positions, breaker（24）In disengaged position, contact structure is off；At this point, circuit one（3）With
Circuit two（4）In connection status, at this moment electric pole one（1）It is not dual power supply bar；
When circuit needs to power hand in hand, electric pole two（10）On disconnecting switch（17）With electric pole four（26）On disconnecting switch
（33）In closing position, breaker（24）In closing position, contact structure is in connection status, by electric pole one（1）Upper end
Panelgirder one（2）Bow line disconnect, circuit one（3）With circuit two（4）It is off, at this moment electric pole one（1）It is dual power supply
Bar；
At this point, staff steps on to electric pole one（1）, use drift bolt（9）By two pieces of anchor ears（5）It is fixed together, dual power supply bar is prevented
Structure is accidentally climbed to install.
