[embodiment]
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
See also Figure 1 and Figure 2, a kind of plateau type high voltage switchgear of the utility model comprises cabinet 1, circuit breaker 2, contact box 3, fixed contact 4, following row 5, current transformer 6, insulating barrier 7, earthed switch 8, insulator 9, bus casing 10, main busbar 11, the last row of propping up 12 and a valve mechanism 13.Cabinet 1 comprises the A of control room, handcart chamber B, bus-bar room C, the D of cable vault;
The utility model comprises a ***ine stem nut mechanism, and leading screw and nut mechanism comprises screw mandrel and nut, and nut is fixed on the circuit breaker 2, and screw mandrel one end connection one is positioned at the turning handle in cabinet 1 outside, and the other end passes nut; Rotate the turning handle in cabinet 1 outside, can realize that just circuit breaker 2 moves in cabinet 1.When the utility model plateau type high voltage switchgear uses, earlier circuit breaker 2 is pushed test position (as shown in Figure 1) in the cabinet 1 outward by cabinet, and handcart advancing mechanism left and right sides stop pin and cabinet are locked.It is firm the subsidiary loop plug to be pegged graft again, and all cabinet doors are shut pinning.Can carry out branch, combined floodgate electric operation by rival car this moment under the situation of major loop access failure.
In the time of handcart will being put into operation, should be earlier separately with earthed switch 8.Again the interlocking of the ground connection on handcart advancing mechanism handle is pulled to low order end.Open with the handle crank then and advance the jack wicket, be inserted into jack, clockwise rotate crank, until advancing clutch to break away from automatically.This moment, circuit breaker 2 was in service position (as shown in Figure 2), and metal dampers is opened, and major loop is connected.Shut its jack wicket with the handle crank, can close, divide operation to it by control loop, and the operation of giving, have a power failure.Remove instrument outdoors this moment, and each cabinet door can't be opened all by locking.
If prepare handcart is withdrawed from from the service position, should confirm that at first circuit breaker 2 at gate-dividing state, opens its jack wicket with the handle crank again, be inserted into jack and rotate counterclockwise crank, up to advancing the automatic disengaging of clutch then to take off crank, close upper handle crank jack.At this moment, circuit breaker 2 has retreated to test position, and major loop disconnects fully, and metal dampers is closed.
If want switching devices to overhaul, the earthed switch 8 that should close earlier, the cabinet door can be opened.Open cabinet behind the door, remove earlier the subsidiary loop plug, the inside more left and right pulling handcart right side, left handle are with the handcart release and pull out outside cabinet.Can switching devices overhaul this moment.
