The device comprises a shell and a circuit board arranged in the shell. The circuit board comprises a CPU chip, a three-way electroscope input circuit, a five-prevention unlock key input detection circuit, and a locking mechanism; the output terminals of the three-way electroscope input circuit and the five-prevention unlock key input detection circuit are individually connected to the input terminal of the CPU chip, the output terminal of the CPU chip is connected to the locking mechanism, a position, which is corresponding to input terminal of the three-way electroscope input circuit, of the shell is provided with three electroscope sensor insert ports, and a position, which is corresponding to input terminal of the five-prevention unlock key input detection circuit, of the shell is provided with a five-prevention unlock key jack. The provided high voltage live display device is used with the error locking preventing system, before the cabinet door is opened, the electricity should be verified, if the electricity verification is failed, the cabinet door cannot be opened, the device has a force locking function, thus the error operation on equipment is effectively prevented, and the safety production of electric system is guaranteed.
Description
Technical field
The invention belongs to field of electrical equipment, especially a kind ofly realize anti-error locking system and the high voltage display device of preventing walking blank operation.
Background technology
Along with the raising day by day of the anti-error level of transformer station, the expanding day of anti-misoperation coverage rate, the serious accident occurred in transformer station reduces year by year.But, because current transformer station middle-high voltage switch " five prevent " block sytem exists hidden danger, switch cubicle anti mis-closedown function imperfection, cannot provide foundation for judging that whether circuit is charged in operation maintenance personnel grid switching operation and maintainer's upkeep operation process, there is certain security risk.
Therefore, we are from the angle preventing electric misoperation, based on electric power safety, project development is included in the category of power system security field macrovisual study, understand and grasp the on-site actual situations of electrical equipment, high voltage display device and anti-error system are combined closely, required for realization anti-walk fool proof object in blank operation and anti-power transmission situation.
Summary of the invention
The object of the invention is to overcome prior art deficiency, the anti-error locking system and the high voltage display device that realize preventing walking blank operation that provide a kind of operating personnel of avoiding to get an electric shock.
The technical solution used in the present invention is:
A kind ofly realize anti-error locking system and the high voltage display device of preventing walking blank operation, comprise housing and be arranged on the circuit board in housing, circuit board comprises cpu chip, No. three electroscope places in circuit, five unlocking prevention key detection circuit for access and blocking mechanisms, the output terminal of No. three electroscope places in circuit and five unlocking prevention key detection circuit for access is connected with cpu chip input end respectively, cpu chip output terminal connects blocking mechanism, the shell position that Yu No. tri-electroscope place in circuit input end is corresponding is respectively arranged with three electrical verification sensors and inserts port, the shell position corresponding with five unlocking prevention key detection circuit for access input ends is provided with five unlocking prevention key sockets, blocking mechanism is used for the locking at gauge tap cabinet interval.
And described No. three electroscope places in circuit are in parallel each other, No. three electroscope places in circuit and five unlocking prevention key detection circuit for access are series circuit.
And be also respectively arranged with three the instruction output circuits corresponding with No. three electroscope places in circuit at described cpu chip output terminal, be separately installed with a LED light at three instruction output circuits, each pilot lamp is all positioned on housing.
Advantage of the present invention and good effect are:
This development project relies on existing anti-error locking system, again high voltage display device is installed additional, the high voltage display device of this Project-developing and anti-error system carry out with the use of, reach out cabinet electrical verification operation in front of the door, electrical verification is by cannot opening switch cabinet cabinet door, there is the function of forced blocking, thus effectively prevent the maloperation to equipment, ensured the safety in production of electric system.The problem that after this system solves operation power personnel mistakenly entering charged chamber well, maloperation is got an electric shock, is embodied in:
(1) live locking function
Microcomputer anti-misoperation system, by supporting the use with high voltage display device, realizes anti-error function, if circuit is charged, locking, forbids opening switch cabinet cabinet door; If circuit is without electricity, then carries out control by the button on computer key and unblank.
(2) convenient anti-error function
Block sytem for switch cubicle only comprises high voltage display device and mechanical coding lock two parts, for each switch cubicle interval, anti-error device is installed simple and convenient, and operations staff's operation is compared over without the need to increasing any equipment, can complete corresponding operating under anti-error monitoring at the scene.Anti-errorly to put in place, simple to operate.
(3) HV live displaying function
The charged situation of circuit that sensor not only can provide by high voltage display device by the clear display of pilot lamp, and can provide coordinated signals signal for computer key, prevents the generation of misoperation fault.
(4) prevent from broadening the scope of work without authorization
High voltage display device coordinates with mechanical coding lock should have forced blocking function, prevents operations staff from broadening the scope of work without authorization, ensures the safety of the person and equipment.
