Description

A kind of temporary ground wire mounting or dismounting status signal extraction element
Technical field
The present invention relates to converting equipment safety check technical field, specifically a kind of temporary ground wire mounting or dismounting status signal extraction element.
Background technology
Along with the development of electric power facility, the microcomputer anti-error technology has obtained widespread use in transformer station, and transformer station has also carried out technological improvement mostly, installs or transform the micro_computer five_proof system additional.And five-preventing system generally directly is not connected with the host computer management system, thereby causes the accident hidden danger easily.
Temporary ground wire is under the jurisdiction of five anti-management systems, is the lifeline that guarantees work about electric power personnel personal safety, and the operation of mounting or dismounting ground wire is dangerous bigger operation in the electric operation, will cause serious consequence in case have an accident.Therefore, how improving the monitoring rate that on-the-spot ground wire is installed and removed state in real time, is the problem that power department is being explored always and solved.
For the mounting or dismounting signal that can pick up ground wire to reach the purpose of anti-misoperation locking, now about main following three kinds of the control measures of temporary ground wire.First kind is to adopt ground state e-management display system, system gives state last and that take off according to ground connection nameplate on liquid crystal display (LCD) screen, automatically the quantity of ground wire and ground connection disconnecting link has been installed at the statistics scene, be presented on light emitting diode (LED) screen, played demonstration and suggesting effect.Second kind is to utilize barcode encoding identification, general packet radio service (GPRS) wireless transmission, GPS (GPS) satellite positioning tech, has set up the management platform that merges basic data management, alarm signal demonstration, temporary ground wire tool management function.The third is a kind ofly to utilize powerful Software Development Platform based on GSM network technology, singlechip technology, automatic control technology and the computer technology research approach in one, develops the anti-error management system of a removable ground wire of cover.
Though above-mentioned existing scheme has realized the extraction of temporary ground wire mounting or dismounting signals, the method more complicated that realizes, these loaded down with trivial details methods have not only been brought the inconvenience of operation to the operations staff, increased dangerous point, also have very big potential safety hazard simultaneously.
Summary of the invention
At above-mentioned deficiency, the invention provides a kind of temporary ground wire mounting or dismounting status signal extraction element, it not only extracts temporary ground wire mounting or dismounting signal, and simple and practical, reduce investment outlay.
The present invention solves the technical scheme that its technical matters takes: a kind of temporary ground wire mounting or dismounting status signal extraction element, it is characterized in that, comprise ground stud and photoelectric sensor, described ground stud is the cylindrical body that is provided with the ground rod patchhole, and is symmetrically arranged with two photoelectric sensor jacks on the cylindrical body; Described photoelectric sensor comprises transmitter and receiver, and described transmitter and receiver are separately positioned in two photoelectric sensor jacks, and described receiver is connected with host computer.
Preferably, described host computer comprises the Power SCADA system.
Preferably, described photoelectric sensor comprises the column type photoelectric sensor, and described column type photoelectric sensor is threaded with the photoelectric sensor jack.
The invention has the beneficial effects as follows: the present invention adopts photoelectric sensor effectively to pick up the mounting or dismounting signal of temporary ground wire, and can carry out the control of locking effectively by the Power SCADA system.
Compare the concrete following superiority of the present invention with the extraction scheme of existing temporary ground wire mounting or dismounting signal:
1) reduces investment outlay.Only improve in former ground stud position, need not additional equipment and complicated signal processing module, save floor area and investment.
2) work efficiency promotes.Directly utilize host computer Power SCADA system to operate, need not to add in addition operating means such as five anti-microcomputers, reduced operation steps, saved the running time, significantly promoted work efficiency.
3) management level improve.Utilize complex automatic system that the mounting or dismounting signal of ground wire is carried out the locking management, can make the management and running personnel grasp the present situation of on-the-spot earthing device rapidly, effectively raise the administration of power networks level.
4) security level is strengthened.The present invention carries out effective locking management to ground wire, has prevented the generation of serious accident, and operation, maintainer's life security has obtained guarantee.
Description of drawings
Fig. 1 is theory diagram of the present invention;
Fig. 2 is the structural representation of ground stud of the present invention;
Among the figure, 1 ground stud, 2 first photoelectric sensor jacks, 3 second photoelectric sensor jacks, 4 photoelectric sensor transmitters, 5 photoelectric sensor receivers, 6 Power SCADA systems, 7 ground rods.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, the present invention will be described in detail.
As depicted in figs. 1 and 2, a kind of temporary ground wire mounting or dismounting status signal extraction element of the present invention, it comprises ground stud 1 and photoelectric sensor, described ground stud 1 is for to be provided with the cylindrical body of ground rod patchhole, and is symmetrically arranged with the first photoelectric sensor jack 2 and the second photoelectric sensor jack 3 on the cylindrical body; Described photoelectric sensor comprises photoelectric sensor transmitter 4 and photoelectric sensor receiver 5, described photoelectric sensor transmitter 4 is arranged in the first photoelectric sensor jack 2, described photoelectric sensor receiver 5 is arranged in the second photoelectric sensor jack 3, in order to the signal that receives photoelectric sensor transmitter 4 and send to the Power SCADA system.
As the preferred version of above-mentioned embodiment, described photoelectric sensor comprises the column type photoelectric sensor, and described column type photoelectric sensor is threaded with the photoelectric sensor jack.
The present invention adopts ground stud as the pickup point of temporary ground wire mounting or dismounting signal, and by transmitter and the receiver of photoelectric sensing apparatus are installed at ground stud, form light signal pickup point.When the ground rod of temporary ground wire inserted ground stud, the passage of light between power valve and the receiving tube just was blocked, and this moment, the photoelectric sensing apparatus was uploaded the information that ground wire has inserted ground rod by optical fiber transport channel to the Power SCADA system.When ground stud did not insert ground rod, the path between transmitter and the receiver was unimpeded, and this moment, the photoelectric sensing apparatus just can be uploaded the signal that ground wire does not insert to the Power SCADA system by optical fiber transport channel.Utilize the present invention, the Power SCADA system conveniently obtains temporary ground wire mounting or dismounting signal, forms effective anti-misoperation locking mechanism with equipment such as switch, disconnecting links again, can effectively prevent the generation of serious accidents such as band ground wire maloperation.
