Embodiment Construction

[0010] Accompanying drawing has shown the structure of transformer anti-theft alarm device of the present invention, and high-voltage line 1 connects the input end of transformer 2, and the body of transformer 2 connects coil 4 on the iron core 6, and coil 4 is powered by power supply 3, and the middle of iron core 6 is armature 5. The armature 5 is supported by the spring 7 to press the push switch 8, the push switch 8 is connected to the alarm circuit 9, and the alarm circuit 9 is connected to the alarm 10. A locking pin 11 can also be arranged between the iron core 6 and the armature 5 . The alarm 10 can be a single flashing light source, a single sound prompter, a loudspeaker in the village, or a small broadcasting speaker connected to each farmer. Not only that, the alarm 10 can also be a flashing light source Or the combination of the voice prompter and the loudspeaker or the farmer's small broadcasting loudspeaker.

Abstract

This invention discloses an anti-stealing alarm device for transformers with an alarm loop characterizing that: the button switch of the loop is pressed by gag bit, the coil on the core of the outer part of the gag bit is connected with the transformer and the coil is supplied by special supply. This invention is especially suitable for the alarm of transformers in the fields far away from villages or non-charge lines.

Description

technical field [0001] The invention relates to an anti-theft alarm device, and directly relates to an anti-theft alarm device for a transformer. Background technique [0002] Over the years, the theft of farmland transformers has been repeatedly prohibited, especially in remote mountainous rural areas, where such sabotage activities are more rampant. The criminal suspects usually commit crimes in the dead of night and when the power equipment is not powered. However, in the vast farmland It is also difficult to arrange personnel to patrol on duty every night. Although there are cases where stronger doors and locks are installed in the power distribution room, the problem cannot be fundamentally solved. At present, alarms are also installed in many public places, but most of them are manually controlled to report to the police. When an emergency situation occurs, it is generally by people to press the alarm to call the police. This kind of alarm still cannot be directly ad...
