Description
Technical field
The utility model relates to a kind of central cabinet grounding switch locking device, belongs to the safety protection field of power equipment.
Background technology
Line-to-ground disconnecting link is the Safety assurance measures of the indispensability ensureing staff in this switch cubicle in circuit and station, so be necessary to the location management of grounding switch, also be that in national grid " electric power safety working regulation ", regulation is accomplished, when closing with unzipped positions, must locking live, forbid that not operation personnel change his state, to cause dangerous and generation that is accident.
At present, 110kV temperature village transformer station 10kV middle-placed switch cabinet, after grounding switch closes, cannot realize five-defence block, if artificially draw grounding switch by mistake, circuit peace is arranged and is removed, and will produce induced voltage, and constitute a threat to line maintenance personnel and electric equipment.
Time normal, grounding switch is at open position, and dolly and switch normal operational position are powered.When service work needs, pull open switch, shaken to test position (or maintenance position) by run location by switch cart, after identifying the true no-voltage of circuit, close grounding switch, after completing the safety measure ensureing staff, can permit work.This grounding switch must be after work all terminates, and has the operational order of scheduling person on duty to pull open again.Therefore necessary locking after the grounding switch that closes, prevent not operation personnel interior malfunction during operation, pull open grounding switch, make staff lose safety precautions, the generation caused the accident.
Service work terminates rear according to dispatch command, by operation human users, pulls open grounding switch, under gate-dividing state, this grounding switch locking is lived, can switch cart being shaken to run location by testing (or maintenance) position, closing a switch, ensureing normal power supply.If do not carry out locking, operating personnel or maintenance and other staff, go to the wrong way interval misoperation, will cause the serious accident of charged co-grounding switch three-phase shortcircuit, will cause device damage and personnel's death, and even cause electric power system large area blackout.Therefore grounding switch must be lived when unzipped positions in locking.
Summary of the invention
The object of this patent is to provide a kind of central cabinet grounding switch locking device, and solving that central cabinet grounding switch closes a floodgate under both middle-placed switch cabinet inspecting states can not the problem of locking.
For achieving the above object, the technical scheme that this patent adopts is,
A kind of central cabinet grounding switch locking device, comprise sheet locking body, described sheet locking body upper side edge protrudes and forms rotation section, described rotation section is provided with screw hole, described sheet locking piece body lower right side establishes the lock hole part perpendicular to locking body, and described lock hole part coordinates padlock nose with middle-placed switch cabinet lockhole, it is characterized in that, described locking body right edge indent, locking body upper right forms the catch portion of protruding rotation section and locking body.
The benefit of this patent is to realize 10kV middle-placed switch cabinet and after grounding switch gets togather, carrys additionally this device realize completely closed, prevent from drawing grounding switch by mistake, compensate for the design defect of original equipment, lose five after avoiding grounding switch to close anti-ly artificially to be pulled open by mistake, ensure that the safety of line maintenance, the overhaul of the equipments person, equipment, improve the reliability of grid switching operation.Invent the anti-snap close of this central cabinet grounding switch five, economical and practical, the locking that can realize five anti-devices is perfect, is expected to popularize in an all-round way in power transformation O&M room.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 4 is that original locking device can not the work sheet of locking under "on" position.
Fig. 5 is three-dimensional structure diagram of the present utility model.
Reference numeral: 1, rotation section; 2, screw hole; 3, catch portion; 4, locking groove; 5, grounding switch; 6, lock hole part; 7, sheet locking body.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The utility model as shown in the figure,
A kind of central cabinet grounding switch locking device, comprise sheet locking body 7, described sheet locking body upper side edge protrudes and forms rotation section 1, described rotation section is provided with screw hole 2, described sheet locking piece body 7 lower right side establishes the lock hole part 6 perpendicular to locking body, and described lock hole part 6 coordinates padlock nose with middle-placed switch cabinet lockhole, it is characterized in that, described locking body 7 right edge indent forms locking groove 4, and locking body upper right forms the catch portion 3 of protruding rotation section 1 and locking body 7.
This device in use, time normal, lock nose and lock by lock hole part and middle-placed switch cabinet, and catch portion is by grounding switch gear at open position, and dolly and switch normal operational position are powered.
When service work needs, pull open switch, switch cart is shaken to test position (or maintenance position) by run location, after identifying the true no-voltage of circuit, open lock hole part lock, close grounding switch 5, both pulled under grounding switch to closing position, again lock hole part and middle-placed switch cabinet are locked nose to lock, catch portion is by grounding switch gear in closing position, and after completing grounding switch, locking prevents not operation personnel interior malfunction during operation.
Service work terminates rear according to dispatch command, by operation human users, and separately grounding switch, under gate-dividing state, this grounding switch is latched in sub-gate position, can switch cart being shaken to run location by testing (or maintenance) position, closing a switch, ensureing normal power supply.If do not carry out locking, operating personnel or maintenance and other staff, go to the wrong way interval misoperation, will cause the serious accident of charged co-grounding switch three-phase shortcircuit, will cause device damage and personnel's death, and even cause electric power system large area blackout.Therefore grounding switch must be lived when unzipped positions in locking.
This patent achieve grounding switch at work with two kinds of situation lockings during maintenance, what avoid original design can only the situation of operationally locking.
