Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As Figure 1-Figure 2, grounding switch locking device, comprise enclosing cover 8, the left side of enclosing cover 8 is provided with the baffle plate 7 of protrusion, right side is hinged by jointed shaft 9 with mounting base 10, enclosing cover 8 can rotate around jointed shaft 9, namely rotate relative to mounting base 10, mounting base 10 is provided with electromagnet 4, electromagnet 4 adopts the electromagnet of direct current 12V, electromagnet 4 is provided with the shift knob 5 controlling its energising power-off, electromagnet 4 is connected with dead bolt 2, electromagnet 4 can drive dead bolt 2 to move, enclosing cover 8 is provided with draw-in groove 1, dead bolt 2 can be stuck in draw-in groove 1 and enclosing cover 1 is covered on mounting base 10.
The downside of enclosing cover 8 is connected with snap close 6, and mounting base 10 is provided with lock nose 3.Utilize common five-proof program lock to pin through lock nose 3, enclosing cover 8 also can be made not open.Mounting base 10 is provided with multiple installing hole.Mounting base 10 is arranged on middle-placed switch cabinet.Baffle plate 7 is provided with handle 12.Conveniently enclosing cover is opened.
The end face of dead bolt 2 is inclined-plane 2.1 as shown in Figure 3.Preferably, the angle of inclination of dead bolt 2 end face is 45 °, and when enclosing cover 8 overturns around jointed shaft 9, cover on mounting base 10, dead bolt 2 snaps in draw-in groove 1, and enclosing cover 8 can not be opened.
Adopt the block sytem of grounding switch locking device, comprise electrification in high voltage transducer, capacitance type sensor is adopted in the present embodiment, as Fig. 5 electrification in high voltage transducer is connected on high-tension line, electrification in high voltage transducer is connected with charged display device, and charged display device is connected with the electromagnet of grounding switch locking device.Charged display device as shown in Figure 4, charged display monitors the signal connect with voltage on the capacitance sensor on distribution line, just illustrates that circuit has electricity.Whether it can indicate the charged situation of three-phase clearly, it has 3 indicator lights 11, indicate A, B, C three-phase charged respectively, represents that circuit is charged When lit.
The blocking method of block sytem, when high-tension line is charged, charged information is given charged display device by electrification in high voltage transducer, and the contact of charged display device disconnects, electromagnet 4 dead electricity, dead bolt 2 is stuck in draw-in groove 1, enclosing cover 8 covers on mounting base 10, and baffle plate 7 keeps off at central-positioned switch cabinet grounding switch operation mouth place, can not open baffle plate 7, cannot operate by update handle, can not grounding switch be closed;
When high-tension line is not charged, the junction closure of charged display device, connect electromagnet 4 power supply, pin shift knob 5, electromagnet 4 is energized, electromagnet 4 adhesive, dead bolt 2 is regained, open enclosing cover 8, grounding switch gathering hole just can not block by such baffle plate 7, then inserts the operation that switch operation handle carries out grounding switch.
When circuit breaker is in test position, when there is electricity in line side, charged display device shows electricity and sends forced blocking, and enclosing cover 8 is locked by dead bolt, and baffle plate 7 keeps off at central-positioned switch cabinet grounding switch operation mouth place, and earthed switch cannot close.
When circuit breaker is in test position, only have when line side is without electricity, and charged display device has electricity and normal, electromagnet has electricity and normal, pins shift knob 5, open enclosing cover 8, can close earthed switch after opening five-proof program lock.Charged display device or electromagnet 4 is arbitrary breaks down or dead electricity, all cannot carry out closing operation.Here " normally " refers to this spacing devices safe and reliable operation, and to line powering, it is normal operation that charged display device shows electricity.When this spacing devices overhauls, this spacing devices has a power failure and does safety measure, and as charged display device shows electricity for abnormal, declaratives equipment live, cannot arrange safety measure (can not close grounding switch), can not carry out upkeep operation.Judge whether normally to carry out according to equipment running status.
Locking grounding switch is the gathering hole utilizing the outer baffle plate covered of locking device to block grounding switch, makes it operate by update handle.Five-proof program lock operation principle is the operating sequence defining the equipment such as the circuit breaker at this interval, circuit breaker cart and grounding switch, locking cannot be realized when circuit has electricity, when grounding switch locking device of the present utility model mainly has an electricity for line side, locking grounding switch closes a floodgate, and occurs to prevent operating accident.Carry out equipment operating not according to regulations stipulate, five-proof program lock cannot be opened, and therefore this grounding switch locking device enclosing cover 8 also cannot be opened locked.Therefore the dead bolt 2 of five-proof program lock and latching electromagnet pins the enclosing cover 8 of grounding switch locking device jointly, when only having two barring conditions all eligible, the enclosing cover 8 of grounding switch locking device just can be opened, and can carry out the operation of grounding switch by update handle after opening.
By reference to the accompanying drawings embodiment of the present utility model is described although above-mentioned; but the restriction not to the utility model protection range; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection range of the present utility model.
