The magnetic induction insulator flashover fault indicator can intelligently monitor power frequency flashover of a pole tower on line in real time, sprays out colored ribbons for indication and suspends the colored ribbons below the indicator when an insulator has power frequency flashover, enables operators to confirm flashover fault spots on ground according to the sprayed colored ribbons without climbing a pole, can effectively solve the problem of circuit fault finding of an electric power system, and provides a forceful means for improving work efficiency, relieving the labor intensity of staff and the like.
Description
Technical field
The utility model relates to the transmission line malfunction indicating equipment of power industry.
Background technology
Along with developing rapidly of power industry, the transmission line of electricity coverage rate constantly enlarges, increasing because of the transmission line of electricity tripping operation accident that thunderbolt, dense fog, filth cause, power frequency earth fault becomes one of recurrent major accident type of transmission line of electricity, brings enormous economic loss to society.After circuit generation power frequency earth fault, must in time find out the trouble spot and removed, classic method is artificial searching, search step by step along the shaft tower of transmission line of electricity by the track walker, work expends lot of manpower and material resources, efficient is extremely low, and may be because of not finding in time that the fault shaft tower leads to large-scale power outage, electric system relevant departments are badly in need of reliable and stable intelligent instrument and equipment and solve this difficult problem.
Summary of the invention
The purpose of this utility model provides a kind of magnetic induction insulator arc-over fault detector, but the power frequency flashover of online in real time intellectual monitoring shaft tower, when insulator generation power frequency flashover, the fault detector ejection indicates with colored ribbon and is hung out under the indicator, the operations staff need not step on bar, can confirm the arcing fault point according to the colored ribbon of ejection on ground, can be fine the solution line fault of electrical power system seek problem, provide a kind of strong means for increasing work efficiency, alleviate intensity of workers etc.
The technical scheme that realizes the utility model purpose is: a kind of magnetic induction insulator arc-over fault detector, form by magnetic induction ring, fixed support, mechanism shell, magnetic striker, internal thread urceolus, spring, outer silk inner core, warning tube and warning weight, magnetic induction ring and mechanism shell all are fixed on the fixed support, in mechanism shell, be provided with magnetic striker, internal thread urceolus, outside silk inner core, report to the police tube, warning weight, the internal thread urceolus and outside card be magnetic striker and spring between the silk inner core, the magnetic striker is stuck in the warning weight in the tube of reporting to the police by the elastic force of spring.
Function and characteristics
1, volume is little, and is in light weight, and simple and fast, safe and reliable is installed.
2, with strong points: only at the power frequency flashover;
The action current of flashover indicator adopts the instantaneous short-circuit power current, when circuit is subjected to be struck by lightning, as long as flashover does not take place insulator, indicator can not move.
3, maintenance cost is cheap: only need reset operation can continue to use behind the indicator motion, be fit to open-air long-time running.
4, uninterrupted monitoring: real-time continual monitoring on the shaft tower.
5, can chargedly install: straight line pole, the strain insulator shaft tower is all applicable.
6, simple in structure, antijamming capability is strong: do not change the insulation system of existing electrical network, the security of operation to existing electrical network does not have any impact, and is convenient to the track walker and searches the insulator chain that flashover took place, and eliminates potential safety hazard potential in the operation of power networks fast.
7, this fault detector can combine with transformer station's line tripping record, and the solution of science is provided for trouble shoot.
Technical indicator
1, fault current can be stablized warning greater than 150A when also lasting 30ms is above.
2, measure demonstration: as arcing fault takes place, equipment sprays bright-coloured blusher band automatically, patrols and examines personnel and just can find far.
3, service condition: outdoor, on-line monitoring.
4, weight 0.5Kg.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
This equipment mainly is made up of magnetic induction ring 1, fixed support 2, mechanism shell 3, magnetic striker 4, internal thread urceolus 5, spring 6, outer silk inner core 7, the tube 8 of reporting to the police, warning weight 9.Magnetic induction ring 1 and mechanism shell 3 all are fixed on the fixed support 2, in mechanism shell 3, be provided with magnetic striker 4, internal thread urceolus 5, outside silk inner core 7, report to the police tube 8, warning weight 9, internal thread urceolus 5 and outside card be magnetic striker 4 and spring 6 between the silk inner core 7, magnetic striker 4 is stuck in warning weight 9 in the tube 8 of reporting to the police by the elastic force of spring 6.
Magnetic induction ring 1 is a most important part in entire equipment, and it is installed on electric power line pole tower step by step continuously, and the ground current value of 24 hours round-the-clock monitoring shaft towers when the power frequency flashover takes place judges whether to take place the power frequency arcing fault.When arcing fault takes place, the tube 8 of reporting to the police is ejected in the sign colored ribbon that warning weight 9 connects later automatically, patrols and examines personnel and just can find far.
Magnetic induction ring 1 adopts electromagnetic induction principle, be that electric current is when flowing through shaft tower, because electromagnetic induction principle magnetic induction ring 1 self just can have magnetic, and inhale moving magnetic striker 4 with this magnetic, after magnetic striker 4 is subjected to magnetic attraction, overcome the elastic force and the recovery of the spring 6 in internal thread urceolus 5 and the outer silk inner core 7, warning weight 9 is fallen from the tube 8 of reporting to the police under action of gravity automatically, be shown as alarm condition.
Take off the semi-circular portion of magnetic induction ring 1, leading role's iron of shaft tower is snapped in the U-shaped flexible fastening groove of fixed support 2, again magnetic induction ring 1 semi-circular portion is snapped in the origin-location.
When shaft tower generation arcing fault, warning weight 9 is ejection from the tube 8 of reporting to the police automatically, and when the personnel of patrolling and examining found to report to the police weight 9, just noting after the shaft tower number of warning and the discovery time can homing device, makes equipment continue to monitor.
Repositioning method: earlier with warning weight 9 slowly fill in the tube 8 of reporting to the police, when hearing slight " click clatter ", the just explanation success that resetted, warning weight 9 has returned to the origin-location, equipment enters the continuation monitoring state.
