Abstract
The utility model discloses a transformer burglar-alarming device that has an alarming circuit. The utility model is characterized in that the button switch of the alarming circuit is pressed by armature, while the loop on the external slew of the armature is channeled with the transformer body. The loop is powered by an exclusive power supply. The utility model is particularly applicable to the burglar alarm system for the transformer arranged far away from the villages in the farm fields. Meanwhile, the utility model is also applicable to the burglar alarm for the no-load electric line wired above the farm fields. The utility model can notify the people to safeguard the electric lines and the transformer equipment in time even if nobody is on duty.
Description
Technical field the utility model relates to burglar alarm, directly relates to the transformer burglar alarm.
Background technology for many years, transformer stolen phenomenon in farmland remains existing despite repeated prohibition, especially in the rural area of remote mountain areas, this destructive activity is more rampant, the suspect generally is in the dead of night and the not power supply state crime of coming out of power equipment, yet in the farmland of the length and breadth of land, be difficult to also accomplish that the personnel of arrangement at night go on patrol on duty everyday.Install more firm door, the situation of lock additional though also have, but can not tackle the problem at its root at switchgear building.At present, alarm has also been installed in a lot of public places, but is mostly the manual control warning, when case of emergency occurs, generally is to press alarm equipment alarm aloud by the people.This alarm still can't directly adopt under the situation of no worker monitor away from the transformer in the village and farmland.
The summary of the invention the purpose of this utility model will provide a kind of improved warning device exactly, and it can solve the existing stolen problem that can't report to the police of farmland transformer effectively.
The purpose of this utility model is achieved in that anti-theft alarm for transformer, has alarm circuit, the pushbutton switch of alarm circuit is pushed by armature by spring action, and the coil on the iron core of armature outside is communicated with the transformer body, and coil is by special power supply power supply.
As further scheme of the present utility model be: between described iron core and the armature lock pin is set.
As the further scheme of another kind of the present utility model be: the alarm in the described alarm circuit comprises the loudspeaker that amplifies.
As another further scheme of the present utility model be: the alarm in the described alarm circuit comprises the newsmonger loudspeaker that insert each peasant household.
The utility model is owing to push the pushbutton switch of alarm circuit by armature; and the coil on the armature outer core is communicated with the transformer body; thereby occur conveniently to report to the police when stolen at transformer; the masses both can by Control Room, also can be by the loudspeaker in the village, can also obtain warning message by the newsmonger loudspeaker in the family, avoid loss thereby can rush for theft illegal activities, protection country and masses' property on-the-spot, that prevent the lawless person fast.
Appended drawings is a structure principle chart of the present utility model, and the utility model is described in further detail below in conjunction with accompanying drawing.
The embodiment accompanying drawing shows the structure of the utility model anti-theft alarm for transformer, high-tension line 1 inserts the input end of transformer 2, the body of transformer 2 inserts the coil 4 on unshakable in one's determination 6, coil 4 is by power supply 3 power supplies, in the middle of unshakable in one's determination 6 is armature 5, armature 5 supports by spring 7 and realizes that push switch 8 inserts alarm circuits 9, inserts alarm 10 in the alarm circuit 9 to the pushing of push switch 8.Also lock pin 11 can be set between iron core 6 and the armature 5.Alarm 10 both can be single flasher, it also can be the single sound prompting device, it can also be the megaphone in the village, can also be the newsmonger loudspeaker that insert each peasant household, moreover, alarm 10 can also be the combination of flasher or auditory tone cues device and megaphone or peasant household's newsmonger loudspeaker.
During the circuit operate as normal, coil 4 energisings on the iron core 6, armature 5 adhesives, spring 7 is compressed, and push switch 8 is in the normally open position, and alarm circuit 9 disconnects, and alarm 10 is static; In case transformer 2 is disassembled, then 4 outages of the coil on the iron core 6, armature 5 is released, under spring 7 effects, armature 5 is depressed push switch 8, and alarm circuit 9 is connected, alarm 10 is reported to the police, and the villager can in time obtain warning message by Control Room or amplify loudspeaker or tame medium and small loudspeaker.For the person of avoiding theft connects coil 4 on unshakable in one's determination 6 once more, makes armature 5 adhesives stop alarm 10 to be reported to the police, this moment lock pin 11 be embedded into unshakable in one's determination 6 and armature 5 between with armature 5 lockings.
The utility model also can be used for the warning of power circuit, can realize as long as the extension line of coil 4 is inserted uncharged power circuit.
