Abstract
A grounded-wire-removing omission-preventing alarm comprises a grounded wire conductive terminal, a PVC element box, a moving contact and a static contact. An indication lamp is mounted to one end of the PVC element box, a wireless signal sensor, a caution loudspeaker and a cell for supplying power are disposed in the PVC element box. An aluminum alloy conductive end plate is fixed in a hook of the grounded wire conductive terminal, a conductive end plate clamping spring is disposed at the outside of the conductive end plate, a cantilever end of the conductive end plate is fixedly connected with the moving contact, and the opposite side of the moving contact is provided with the static contact with an adjustable height. When the grounded wire conductive terminal is mounted to a bus, the moving contact opens along with the conductive terminal to close with the static contact, a loop of a device is conducted, and the caution loudspeaker and the indication lamp of the PVC element box are triggered, so a usage state of a ground wire can be reported at set intervals to caution a worker to be careful. The grounded-wire-removing omission-preventing alarm has functions of prompting through voice and light, safety risks of switching on with a grounded wire can be eradicated effectively, and a safety defense line can be added for safety operation of an electrical network.
Description
Technical field
The utility model relates to the safe dismounting technical field of power equipment ground wire, particularly relates to ground wire leakproof and tears alarm open.
Background technology
In electric system, ground wire is the visual plant that ensures maintainer's life security, and therefore, in " electric power safety working regulation ", the mounting or dismounting of earth wire require very strict.The charged maintainer's of jeopardizing life security suddenly in order to prevent from overhauling power equipment, before service work, must ground wire be installed in repair apparatus side, after finishing, service work removes again these ground wires, but it is more in large maintenance place, ground wire to be installed, or the unclear Overhaul site of sight line at night, particularly indoor low-pressure section or substation, exist through walls, wear in cabinet ground wire situation, moreover ground wire does not have again sound, the prompting of light etc., maintainer is easy to forget the some ground wires of dismounting, be retained in scene, will cause the serious maloperation with ground wire power transmission, in accident, just there is the pernicious misoperation fault with ground wire power transmission in the past, this kind of accident analyzed as typical case by Circuits System always, educational system worker, and constantly for everybody sounds the alarm.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of ground wire to use once installing, can constantly remind field personnel to note ground wire service condition at the scene, thoroughly stops the ground wire leakproof of the potential safety hazard of closing a floodgate with ground wire and tears alarm open.
The technical scheme adopting is:
Alarm is torn in ground wire leakproof open, ground wire conducting end, PVC subassembly wrapper, moving contact, static contact, warning loudspeaker, pilot lamp, wireless signal sensor supplying cell.Described PVC subassembly wrapper is fixedly connected in ground wire conducting end, and one end of PVC subassembly wrapper is provided with pilot lamp, is equiped with the battery of wireless signal sensor, warning loudspeaker and power supply in PVC subassembly wrapper.In the hook of described ground wire conducting end, be installed with aluminium alloy conducting end plates, conducting end plates outside is provided with conducting end plates jump ring, conducting end plates expansible, can under the effect of conducting end plates jump ring, merge again, the cantilever end of described conducting end plates is fixedly connected with moving contact, the offside of moving contact arranges static contact, and static contact is connected on PVC subassembly wrapper, and static contact height is adjustable.When ground wire conducting end is installed on bus, bus opens conducting end plates, moving contact opens with static contact closed with conducting end plates, conducting device loop, trigger warning loudspeaker and pilot lamp on PVC subassembly wrapper, report at set intervals the use state of ground wire, constantly remind operating personnel to take care.
The battery of above-mentioned power supply also can be solar energy collecting plate.
Above-mentioned pilot lamp is LED stroboscopic lamp.
Above-mentioned wireless signal sensor signal connects receiver in wireless sensing signal cabin.
The utlity model has voice and light prompt function, be more suitable for indoor low-pressure section or substation, exist through walls, while wearing cabinet wiring and in the very dark situation of the outdoor colour of sky, use.Ground wire is used once installing, can constantly remind field personnel to note ground wire service condition at the scene, can effectively stop the security risk with ground wire combined floodgate, for electric power netting safe running adds security perimeter again one.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Alarm is torn in ground wire leakproof open, ground wire conducting end 1, PVC subassembly wrapper 8, moving contact 4, static contact 5, warning loudspeaker 6, pilot lamp 10, wireless signal sensor 7, supplying cell 9.Described PVC subassembly wrapper 8 is fixedly connected in the ground wire conducting end 1 of aluminum alloy square tube making, one end of PVC subassembly wrapper 8 is provided with the pilot lamp 10 of LED stroboscopic lamp formula, in PVC subassembly wrapper 8, be equiped with the battery 9 of wireless signal sensor 7, warning loudspeaker 6 and power supply, wherein wireless signal sensor 7 signals connect receiver in wireless sensing signal cabin.In the hook of described ground wire conducting end 1, be installed with aluminium alloy conducting end plates 2, conducting end plates 2 outsides are provided with conducting end plates jump ring 3, conducting end plates expansible, can under the effect of conducting end plates jump ring, merge again, the cantilever end of described conducting end plates 2 is fixedly connected with moving contact 4, the offside of moving contact 4 arranges static contact 5, and static contact 5 is connected on PVC subassembly wrapper 8, and static contact 5 is highly adjustable.When ground wire conducting end 1 is installed on bus, bus opens conducting end plates, moving contact 4 opens and static contact 5 closures with conducting end plates, conducting device loop, trigger warning loudspeaker 6 and pilot lamp 10 on PVC subassembly wrapper 8, report at set intervals the use state of ground wire, constantly remind operating personnel to take care.
