Abstract
An alarm preventing a grounding wire from being left out in disassembling comprises a grounding wire conductive end, a PVC component box, a moving contact and a fixed contact. An indicator lamp is installed at one end of the PVC component box, and a wireless signal sensor, a warning loudspeaker and a battery for supplying electricity are arranged in the PVC component box. An aluminum alloy conductive end plate is fixedly arranged in a hook at the conductive end of the grounding wire, a conductive end plate snap spring is arranged on the outer side of the conductive end plate, the moving contact is fixedly connected to a cantilever end of the conductive end plate, and the fixed contact with an adjustable height is arranged on the opposite side of the moving contact. When the conductive end of the grounding wire is arranged on a busbar, the moving contact opens along with the conductive end to be combined with the fixed contact, a circuit of the device is communicated, the warning loudspeaker and the indicator lamp on the PVC component box are triggered, the using state of the grounding wire is broadcast every once in a while, and operating staff are timely reminded to pay attention to safety. The alarm has voice and light prompt functions, can effectively eliminate safety risks of switching on of the grounding wire, and additionally provides a safety defensive line for safe operation of a power grid.
Description
Technical field
The present invention relates to the safe dismounting technical field of power equipment ground wire, particularly relate to the ground wire leakproof and tear 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 the 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., the maintainer is easy to forget the some ground wires of dismounting, be retained in scene, will cause the serious maloperation with the ground wire power transmission, pernicious misoperation fault with the ground wire power transmission was just arranged in accident in the past, this kind of accident analyzed as typical case by Circuits System always, the educational system worker, and constantly for everybody, sound the alarm.
The technical problem to be solved in the present invention is, provides a kind of ground wire to use once installing, can constantly remind the 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 adopted is:
Alarm is torn in the ground wire leakproof open, ground wire conducting end, PVC subassembly wrapper, moving contact, static contact, warning loudspeaker, pilot lamp, wireless signal sensor.Described PVC subassembly wrapper is fixedly connected on the ground wire conducting end, and an end of PVC subassembly wrapper is equipped with pilot lamp, is equiped with the battery of wireless signal sensor, warning loudspeaker and power supply in the PVC subassembly wrapper.Be installed with the aluminium alloy conducting end plates in the hook of described ground wire conducting end, the conducting end plates outside is provided with the conducting end plates jump ring, the 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 the PVC subassembly wrapper, and the static contact height is adjustable.When the ground wire conducting end is installed on bus, bus opens conducting end plates, moving contact opens and the static contact closure with conducting end plates, the conducting device loop, trigger warning loudspeaker and pilot lamp on the PVC subassembly wrapper, report at set intervals the use state of ground wire, constantly remind the operating personnel to take care.
The battery of above-mentioned power supply also can be solar energy collecting plate.
Above-mentioned pilot lamp is the LED stroboscopic lamp.
Above-mentioned wireless signal sensor signal connects receiver in the wireless sensing signal cabin.
The present invention has voice and light prompt function, is more suitable for indoor low-pressure section or substation, exist through walls, while wearing the cabinet wiring and in the very dark situation of the outdoor colour of sky, use.Ground wire is used once installing, can constantly remind the field personnel to note ground wire service condition at the scene, can effectively stop the security risk of closing a floodgate with ground wire, for electric power netting safe running adds security perimeter again one.
the accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
embodiment
Alarm is torn in the 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.Described PVC subassembly wrapper 8 is fixedly connected on the ground wire conducting end 1 of aluminum alloy square tube making, one end of PVC subassembly wrapper 8 is equipped with the pilot lamp 10 of LED stroboscopic lamp formula, be equiped with the battery 9 of wireless signal sensor 7, warning loudspeaker 6 and power supply in PVC subassembly wrapper 8, wherein wireless signal sensor 7 signals connect receiver in the wireless sensing signal cabin.Be installed with aluminium alloy conducting end plates 2 in the hook of described ground wire conducting end 1, conducting end plates 2 outsides are provided with conducting end plates jump ring 3, the 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, the 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 the operating personnel to take care.
