Background technology
Production both at home and abroad, the 10KV high-tension switch cabinet used, the basic grounding switchs that all are equipped with, when grounding switch proper operation, use, play great role to the protection personal injury, and improper use, tend to cause a serious accident.Tool statistics, in China's electric accident, the 18%th, because the live grounding misoperation disconnecting link causes.The live grounding misoperation disconnecting link, the lighter causes circuit breaker trip, system blackout, severe one causes human casualty accident.The charged anti-misoperation grounding switch used at present, generally adopt micro_computer five_proof and machinery five anti-, good effect arranged, but still have defect.Micro_computer five_proof exists investment huge, and system is huge, wiring is loaded down with trivial details, the shortcoming of troublesome poeration; Machinery five is prevented having high, the easy to wear inefficacy of requirement on machining accuracy, poor reliability, can not reminding in time operating personnel whether to operate correct shortcoming.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency provides a kind of high-tension switch cabinet charged anti-misoperation grounding knife device.
For achieving the above object, the utility model is by the following technical solutions:
The charged anti-misoperation grounding knife device of a kind of high-tension switch cabinet, comprise base, one end of base arranges slidably transmission mechanism, the top of transmission mechanism is provided with electromagnetic mechanism corresponding thereto, electromagnetic mechanism is arranged on support, be provided with moving contact on base, moving contact is corresponding with electromagnetic mechanism, be provided with spring between transmission mechanism and moving contact, the other end of base is provided with insulation column, the insulation column top arranges fixed contact, binding post is established in the fixed contact end, moving contact is corresponding with fixed contact, also be provided with circuit breaker on fixed contact, also comprise electric appliance box and handle, be provided with controller in electric appliance box, in the electric appliance box outer setting, pressure switch is arranged, be provided with the pressure sensing contact on pressure switch, be provided with the handle patchhole at the pressure sensing contact between corresponding electric appliance box and support, the elongated end of transmission mechanism is in the handle patchhole, pressure-sensitive switch is electrically connected to controller, also be provided with voltage transformer on circuit breaker, voltage transformer is electrically connected to controller, the position corresponding at circuit breaker also is provided with auxiliary contact of breaker, auxiliary contact of breaker is electrically connected to controller.
The charged anti-misoperation grounding knife device of above-mentioned high-tension switch cabinet also is provided with loud speaker in controller, and loud speaker is connected with controller.
Adopt technique scheme, the utility model has following advantage: whether bus is charged, can complete by voltage transformer, circuit breaker deciliter state can judge by the auxiliary contact of circuit breaker, voltage transformer and auxiliary contact of breaker all are electrically connected to controller, judge that by controller is dual whether high-voltage board is charged, controller can adopt the existing single-chip microcomputer in market to complete.
The utility model adopt to detect in high-voltage board the whether condition such as disjunction of the whether charged and circuit breaker of bus, by double condition, judges that whether high-voltage board is charged, changes the method that traditional single condition is done criterion, and reliability is higher.Invest that little, wiring is simple, machining accuracy require low, reliability is high.
By the whether charged and circuit breaker of bus, whether disjunction shows judgement, controller is controlled electromagnetic mechanism and is produced electromagnetic force, promote moving contact and overcome spring force, the high transmission mechanism that presses off grounding switch in the magnetic cabinet of locking, make the grounding switch akinesia, prevent earthing misoperation in the charged situation of high-voltage board, the prevention electric accident occurs.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The charged anti-misoperation grounding knife device of a kind of high-tension switch cabinet as shown in Figure 1, comprise base 11, one end of base 11 arranges slidably transmission mechanism 3, the top of transmission mechanism 3 is provided with electromagnetic mechanism 4 corresponding thereto, electromagnetic mechanism is arranged on support 17, be provided with moving contact 5 on base, moving contact 5 is corresponding with electromagnetic mechanism, be provided with spring between transmission mechanism and moving contact, the other end of base 11 is provided with insulation column 10, insulation column 10 tops arrange fixed contact 6, binding post 14 is established in fixed contact 6 ends, moving contact 5 is corresponding with fixed contact 6, also be provided with circuit breaker 8 on fixed contact, also comprise electric appliance box and handle 1, be provided with controller 13 in electric appliance box, in the electric appliance box outer setting, pressure switch 2 is arranged, be provided with pressure sensing contact 15 on pressure switch 2, be provided with handle patchhole 16 between the electric appliance box of pressure sensing contact 15 correspondences and support, the position that the elongated end of transmission mechanism 3 is corresponding at the handle patchhole, pressure-sensitive switch 2 is electrically connected to controller 13, also be provided with voltage transformer 7 on circuit breaker 8, voltage transformer is electrically connected to controller 13, position in circuit breaker 8 correspondences also is provided with auxiliary contact of breaker 9, auxiliary contact of breaker 9 is electrically connected to controller.Also be provided with loud speaker 12 in controller, loud speaker 12 is connected with controller, and loud speaker plays the function of voice suggestion, can in controller, add voice module to complete, and voice module adopts existing loud speaker on market.Whether can operating function, can at utmost avoid the generation of live grounding misoperation disconnecting link accident if having in good time voice reminder.
The course of work of the present utility model is as follows: the utility model is handle update hole when operation, handle is depressed pressure switch, the cut-in pressure sensor contact, pressure switch is uploaded signal,, circuit breaker whether charged to bus in high-tension switch cabinet by the controller whether condition such as disjunction contrasted, send alerting signal when charged, make loud speaker send " equipment live please don't operate " suggestion voice.Also send alerting signal when not charged, make loud speaker send " circuit breaker is disjunction, can operate " suggestion voice.Controller of the present utility model and loud speaker all can have been bought from the market, are prior aries.
