The utility model adopts one shaft to complete the dividing position and the closed position which are synchronous with bit codes. The utility model adopts a contactless reflection type photocoupler, the encoding plate is flatly stuck on the side face of the lock body, bit codes are arranged in the lock body, and the computer key has the functions that the computer key is straightly inserted, is straightly pulled, and is not rotated to unlock.
Description
The utility model is a kind of high voltage switchgear system controlled by computer anti-misoperation locking, and it is applicable to power plant, the transformer station of various electric pressures and any complicated wiring.
Continuous development along with China's electric utility prevents the generation of electric fault-operation accident, and it is very necessary that the error-proof device with mandatory blocking function is installed.But traditional Mechanically programm's locking device and electromagnetic locking device can not satisfy the requirement that electric power safety is produced fully to the complicated station of primary connection, it is complex operation not only, poor reliability, simultaneously electromagnetic lock is also wanted cabling, so can not prevent the generation of misoperation fault on the technical measures at all.At present the DNBS series of products of Shanxi, Zhuhai electricity are arranged is based on Mechanical ring latch to the shutting device to prevent mistakes in microcomputer that uses of China, can not the consersion unit physical location, walk dummy routine easily; Although a new generation has installed branch additional, closed position detecting device, but still can not prevent away dummy routine, and increased operations staff's trouble again; Promptly arrive half position in operation of equipment, position detector detects with regard to available key by open position.Also have the product of producers such as dig altogether in Zhuhai, Jiangxi wind and cloud, Lanzhou wind and cloud that the contact is all arranged, computer key adopts contact to adopt sign indicating number, unblanks with the handle rotation when unblanking, and it is unreliable to use.The mechanical lock of Xiangfan concerted effort is a cross-compound arrangement, and two chips all stand upright on the lock body, and the distortion of very easily colliding with is equipped with padlock in addition, easily walks dummy routine.
The purpose of this utility model is a kind of high voltage switchgear system controlled by computer anti-misoperation locking of developing at the deficiency of above product, it can simulate the mode of operation of existing equipment, at the operating habit that does not change operating personnel, under the situation that does not increase operating personnel's burden, and can realize forced blocking.In the mimic panel of this product industrial control host is installed, be solidified with " five is anti-" locking expert system in the main frame, after operating personnel receive dispatching command, can be on intelligent simulation board simulated operation, display operation content is item by item shielded in Chinese display, expert system is carried out " five is anti-" to content of operation item by item and is judged, and provide with speech form, after simulated operation is finished, industrial control host is given computer key with all operations content delivery, operating personnel press content of operation that computer key shows to execute-in-place, at first the key straight cutting are gone in the corresponding encoded lock, adopt sign indicating number correctly after, can operate by the origin operation mode, the actual branch of operation back computer key recording equipment, close state, and state information is fed back to intelligent simulation board, realized the equipment contraposition under no cable.
The utility model is achieved in that high voltage switchgear comprises lockset and computer key with the system controlled by computer anti-misoperation locking, wherein, lock shaft 6 and bit code piece 12 are housed in the lock body 7, and bit code piece 12 is contained on the lock shaft 6 by pin 11, and the side of lock body 7 is smooth coded slice 13; Unblank on the computer key pin 18, transmission pin 19 and adopt sign indicating number probe 20.
The utility model can also be achieved in that the pin-and-hole B that unblanks, transmission pin-and-hole E, bit code hole D and code-locked hole H on coded slice 13.
The utility model can be such realization also: adopt sign indicating number probe 20 and adopt contactless reflecting photoelectric coupler.
Good effect of the present utility model is:
1, this product is that advanced person's microelectric technique is combined with mechanical locking device reliably, is used to prevent electric misoperation, and it is applicable to power plant, the transformer station of various electric pressures and any complicated wiring.
2, this product has perfect " five is anti-" function, realizes mandatory locking, does not walk " dummy routine ", finishes lock to divide, close the position synchronous with bit code for one.The sign indicating number probe of adopting of computer key is to adopt contactless reflecting photoelectric coupler to adopt sign indicating number, the smooth lock body of chip one side, and bit code is in lock body, and computer key has straight cutting, directly pulls out, do not rotate the function of unblanking.
