Embodiment
Below in conjunction with Figure of description and embodiment, the utility model content is described in detail:
The embodiment schematic diagram of the switch-interlocking mechanism of a kind of cutter electrically provided for the utility model as shown in Figures 1 to 5, it comprises
Earthing operation bent plate 1, described earthing operation bent plate 1 offers the ground tool bore 1-1 for manual operation cutter on/off switch electrically;
Sensitive switch 2, described sensitive switch 2 is located on earthing operation bent plate 1, for controlling the electric operating connecting and disconnecting of the circuit of cutter electrically;
Ground tool bore baffle plate 3, described ground tool bore baffle plate 3 is hinged on earthing operation bent plate 1, and rotate between sensitive switch 2 and ground tool bore 1-1, the jointed shaft of ground tool bore baffle plate 3 is arranged with reduction torsion spring 4, described reduction torsion spring 4 makes the initial condition of ground tool bore baffle plate 3 be positioned on ground tool bore 1-1, and ground tool bore baffle plate 3 rotates rear shake-up sensitive switch 2.
During initial condition, ground tool bore baffle plate 3 blocks residence tool bore 1-1, and operating personnel impenetrably tool bore 1-1 carry out manual opening-closing to earthing; And sensitive switch 2 is in connected state, pressing cutter starting switch DD electrically just can electric operating earthing on/off switch.
Local tool bore baffle plate 3 turns to sensitive switch 2 and presses the button on it, and sensitive switch 2 disconnects, and cannot be carried out the on/off switch of earthing by electric operating; And ground tool bore 1-1 is in and exposes state, operating personnel by tool bore 1-1 just can carry out manual opening-closing to earthing.
Above-mentioned design ensure that an earthing mode of can selecting realizes on/off switch, and electric operating and manual operation can not be disturbed mutually.
In order to improve the fail safe of cutter electrically further, whether it also comprises charged for interval after detecting box and controls the charged display transducer of the electric operating connecting and disconnecting of the circuit of cutter electrically, and charged display transducer and sensitive switch 2 are in series.
Because operating personnel need to operate in interval after cabinet, therefore can not be charged on it when needing guarantee to enter interval after cabinet.Charged display transducer is set, when the charged time control electric operating circuit of interval after cabinet disconnects, cannot electric operating earthing on/off switch.
It also comprises the electromagnetic lock 5 rotated for limiting ground tool bore baffle plate 3, and the function circuit of described electromagnetic lock 5 controls break-make by charged display transducer.
Described ground tool bore baffle plate 3 comprises locking bottom plate 3-1, and described locking bottom plate 3-1 is provided with the lock hole holding electromagnetic lock 5 bullet bolt and pass.
When charged display transducer detects that interval is charged after cabinet, not only to disconnect electric operating circuit, electric operating cannot be realized, also need to ensure that manual operation cannot complete simultaneously, namely will limit the rotation of ground tool bore baffle plate 3.
When charged display transducer detects that after cabinet, interval is charged, uncontrollable electromagnetic lock 5 operates, and the bullet bolt on electromagnetic lock 5 is plugged in lock hole all the time, and ground tool bore baffle plate 3 cannot rotate.
When charged display transducer detects that after cabinet, interval is not charged, control electromagnetic lock 5 and make bullet bolt deviate from lock hole, ground tool bore baffle plate 3 is free to rotate.
Described ground tool bore baffle plate 3 is provided with the driving lever 3-2 extended to earthing operation bent plate 1 lateral direction, described earthing operation bent plate 1 offers appearance driving lever 3-2 and passes and the arc opening 1-2 slided.Operating personnel by driving lever 3-2 from tool bore baffle plate 3 rotationally outside earthing operation bent plate 1.
Described earthing operation bent plate 1 is provided with spring backstay 1-3, and described reduction torsion spring 4 one support arm is resisted against on spring backstay 1-3, and another support arm is resisted against on ground tool bore baffle plate 3.
Described ground tool bore baffle plate 3 also comprises side plate 3-3, and described side plate 3-3 triggers sensitive switch 2 when local tool bore baffle plate 3 turns to sensitive switch 2 position.
Figure 5 shows that the schematic diagram of the electric operating circuit of cutter electrically, wherein sensitive switch LK, handcart experimental site transducer CZ, charged display transducer DDXS, electrically cutter starting switch DD, electrically cutter motor M and AC power KM are in series.
In 10kV middle-placed switch cabinet, the operation of earthing on/off switch just must to allow in the not charged situation in handcart interval after experimental site, cabinet to operate meeting.
Arrange in the utility model handcart be defaulted as and handcart closed at experimental site, handcart experimental site transducer CZ switch with cutter operating mechanism interlock and unlock.Be below the switch-interlocking mechanism operation example of cutter electrically:
1, after cabinet, the charged then charged display transducer DDXS in interval disconnects, cannot electronic startup cutter motor M electrically, and electric operating cannot realize; And electromagnetic lock 5 pins ground tool bore baffle plate 3, manual operation also cannot realize.
2, after cabinet, the not charged then charged display transducer DDXS in interval closes, and sensitive switch 2 is in original closure state, presses cutter starting switch DD electrically, can realize electric operating earthing on/off switch.
3, after cabinet, interval is not charged, and charged display transducer DDXS closes and electromagnetic lock 5 unlocks, tool bore baffle plate 3 makes sensitive switch 2 disconnect while exposing ground tool bore 1-1 rotationally, the electric operating circuit automatically cutting off cutter electrically can be realized, manual operation earthing on/off switch can only be carried out.
If 4, during manual operation, operating grip does not take out, then handle will block ground tool bore baffle plate 3 and makes it reset, even if now press cutter starting switch DD electrically, earthing also can not action, prevents from driving ground cutter operating grip rotate and cause Field Force injured when swivel moves electrically.
