Abstract
The utility model relates to a safe transformer substation ground wire disassembling tool, in particular to a neglected ground wire disassembly alarm apparatus. The neglected ground wire disassembly alarm apparatus comprises a power supply, an alarming lamp bulb, an alarming horn, a power switch and a normally-closed contact which are connected in series to form a loop. A hook for hanging a ground wire is arranged under the normally-closed contact, and the lower portion of the normally-closed contact is connected with a reset spring enabling the normally-closed contact to reset and to be closed upward. When the ground wire is taken, the alarming lamp bulb can give a flare, and the alarming horn makes sound to remind a worker that the ground wire is not in place. The ground wire is hung on the hook after used, and the alarming lamp bulb and the alarming horn stop working, so that the severe problem that a device with the left ground wire forgotten to be dismantled after used is sent to a field is thoroughly solved.
Description
Technical field
The utility model relates to the safe mounting or dismounting tools of transformer substation grounding wire, is specifically related to a kind of ground wire leakage and tears alarm open.
Background technology
According to " electric power safety working regulation " requirement, the technical measures of trouble free service are on electrical equipment: " power failure, electrical verification, ground connection, suspension nameplate and installing cover bar ".Wherein " ground connection " just refers to install ground wire or splice grafting ground disconnecting link, also regulation: " every winding ground wire all should be numbered, and leaves the fixed location in.Storage place should be numbered, and the ground wire number should be consistent with the deposit position number.Dress, dismounting ground wire should be carried out record, should explain clear when relieving." as seen, in safety, the requirement of earth wire is very high, the ground wire mounting or dismounting are left over, and will cause the serious maloperation with the ground wire power transmission.We also usually see the accident with the ground wire power transmission in the past in accident case.Particularly in the grid switching operation of full site type, ground wire uses intensive, manually checks, and especially easily causes and leaves over, thereby bring hidden danger to safety in production.
The utility model content
The purpose of this utility model is to provide a kind of ground wire to leak and tears alarm open, solves at present in transformer station easily to leave over during at the dismounting ground wire, causes the problem with the ground wire power transmission.
For solving above-mentioned technical matters, the utility model is by the following technical solutions: a kind of ground wire leaks tears alarm open, comprise that mutual series connection consists of power supply, warning bulb, alarming horn, power switch and the normally closed contact in loop, the below of gained normally closed contact is provided with the hook of hanging earthing conductor and is connected with the back-moving spring that makes normally closed contact upwards reset closure.
Compared with prior art, the beneficial effects of the utility model are: the utility model can be when ground wire be taken, the warning bulb flashes, alarming horn sends the sound, to remind the not playback of staff's ground wire this moment, again hang over after ground wire is finished using on hook, warning bulb and alarming horn quit work, and stop ground wire with this and have forgotten dismounting and leave over and cause the equipment belt ground wire to send a little serious problems after use.
Description of drawings
Fig. 1 is that the utility model ground wire leaks the annexation figure that tears an embodiment of alarm open.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Fig. 1 shows the utility model ground wire and leaks an embodiment who tears alarm open: a kind of ground wire leaks tears alarm open, comprise that mutual series connection consists of power supply 1, warning bulb 2, alarming horn 3, power switch 4 and the normally closed contact 5 in loop, the below of gained normally closed contact 5 is provided with the hook 6 of hanging earthing conductor and is connected with the back-moving spring 7 that makes normally closed contact 5 upwards reset closure.
when ground wire hangs on hook 6, deadweight due to ground wire, to link up with 6 all pulls downwards together with normally closed contact 5, make the loop disconnection at normally closed contact 5 places, warning bulb 2 and alarming horn 3 dead electricity are not worked like this, after the staff takes ground wire away, normally closed contact 5 and hook 6 are because the pulling force of back-moving spring 7 moves up, make circuit closed, at this moment report to the police bulb 2 and alarming horn 3 electric work, remind ground wire not playback to the staff, only have ground wire finish using and again hang hang back on hook 6 after, warning bulb 2 and alarming horn 3 just can stop reminding.
Although with reference to a plurality of explanatory embodiment of the present utility model, the utility model is described here, but, should be appreciated that, those skilled in the art can design a lot of other modification and embodiments, and these are revised and within embodiment will drop on the disclosed principle scope and spirit of the application.More particularly, in the scope of, accompanying drawing open in the application and claim, can carry out multiple modification and improvement to building block and/or the layout of subject combination layout.Except modification that building block and/or layout are carried out with improving, to those skilled in the art, other purposes will be also obvious.
Claims (1)
