Abstract
The invention relates to the prompt alarm due to the fact that a safety short circuit device (or part) is not dismounted by rule or forgotten to be dismounted in the electric power circuit construction, in particular to a method for preventing the electric power circuit safety short circuit device from being left. The method solves the problem that the safety short circuit device leaving prompt alarm technology lacks in the electric power circuit construction. Two small radar ranging and alarming meters which are used in pairs and have a distance setting function are selected and used, one of the small radar ranging and alarming meters with the distance setting function is installed on the short circuit device, the other small radar ranging and alarming meter with the distance setting function is carried by a constructor on a rod, a needed separation distance alarm value between the two ranging and alarming meters is set, then the two ranging and alarming meters start monitoring the distance between the two ranging and alarming meters in real time, and when the constructor on the rod does not dismount the short circuit device and displaces and goes down the rod, the two ranging and alarming meters monitor that the distance between the two ranging and alarming meters exceeds the separation distance alarm value to give an alarm signal.
Description
Technical field
The present invention relates to safe short-circuit device (or parts) in power line construction and, not by regulation dismounting or the prompting warning forgetting dismounting, be specially the method preventing the safe short-circuit device of power circuit from leaving over.
Background technology
There are the people of electric line operation experience all clear, in dead line operation or construction of line process, on bar, workmen will according to the requirement of safety in production operating regulation, first want electrical verification before work, hang short-circuit grounding wire, on bar of being allowed for access, construction operation or service work are carried out in working site.Procedure operation terminates, and on the short-circuit device and other species that affect circuit power transmission, staff should carry out removing and processing item by item, confirm errorless after, work director can report step by step, application power transmission.Because operating personnel on bar is few, the activity duration is long, physical demands is large, add ground monitoring, check not in place; , because failing to remove ground wire or short-circuit device in time, there is trip accident after causing circuit power transmission in end-of-job, even causes power failure severe and great casualty in system station to happen occasionally.Owing to lacking the technical support that prompting is reported to the police, although relevant departments have carried out safe rectification and strictly dealt with the work to accident responsibility people, be still difficult to the generation of stopping this type of accident even to this day.
Summary of the invention
The present invention solves in power line construction and lacks the problem that safe short-circuit device leaves over prompting alarm technique, provides a kind of method preventing the safe short-circuit device of power circuit from leaving over.
The present invention adopts following technical scheme to realize: prevent the method that the safe short-circuit device of power circuit is left over, the distance that has selecting two to use in pairs arranges miniradar range finding and the alarm of function, the miniradar range finding first having distance to arrange function by one and alarm are arranged on short-circuit device (as earth connection), another miniradar having distance to arrange function is found range and alarm is carried by workmen on bar, two range findings needed for setting and the separating distance alarming value between alarm, two range findings and alarm start Real-Time Monitoring distance between the two, when workmen on bar is shifted lower beam not dismantling safe short-circuit device, alarm signal is sent when two range findings and the alarm distance monitored between the two exceed separating distance alarming value.
The method of the invention is applicable to operation on each electric pressure bar, after power failure end-of-job, remind workmen at any time, the safe short-circuit devices such as the short-circuit grounding wire do not removed are removed in time, effectively stop people for liability accident generation, reduce circuit breaking rate, guarantee line powering reliability.
Embodiment
Prevent the method that the safe short-circuit device of power circuit is left over, the distance that has selecting two to use in pairs arranges miniradar range finding and the alarm of function, the miniradar range finding first having distance to arrange function by one and alarm are arranged on short-circuit device (as earth connection), another miniradar having distance to arrange function is found range and alarm is carried by workmen on bar, two range findings needed for setting and the separating distance alarming value between alarm, two range findings and alarm start Real-Time Monitoring distance between the two, when workmen on bar is shifted lower beam not dismantling safe short-circuit device, alarm signal is sent when two range findings and the alarm distance monitored between the two exceed separating distance alarming value.Described have distance that function is set miniradar range finding and alarm be known existing product, or one of ordinary skill in the art easily design and obtain.
Claims (1)
1. the method preventing the safe short-circuit device of power circuit from leaving over, it is characterized in that the distance that has selecting two to use in pairs arranges miniradar range finding and the alarm of function, the miniradar range finding first having distance to arrange function by one and alarm are arranged on short-circuit device, another miniradar having distance to arrange function is found range and alarm is carried by workmen on bar, two range findings needed for setting and the separating distance alarming value between alarm, two range findings and alarm start Real-Time Monitoring distance between the two, when workmen on bar is shifted lower beam not dismantling safe short-circuit device, alarm signal is sent when two range findings and the alarm distance monitored between the two exceed separating distance alarming value.
