Abstract
The invention discloses a transformer antitheft alarm which comprises a transformer, an alarming relay, a buzzer, an alarming indicator lamp and an emergency power source. The transformer antitheft alarm can effectively prevent the transformer from being stolen; when the transformer is stolen, a normally-closed contact of the relay is connected, the buzzer and the alarming indicator lamp are electrified to give an alarm, personnel on duty hears the alarm of the transformer antitheft alarm and goes to the place where the transformer is positioned to check, and the transformer is effectively prevented from being stolen.
Description
Technical field
The present invention relates to a kind of transformer anti-theft alarm.
Background technology
At present along with the application of social progressive anti-theft device is general all the more, yet the alarm kind on market is a lot, but still lack the warning device for switchgear building transformer anti-theft, alarm on market mostly can not provide to have a power failure and report to the police, transformer can not send timely warning when being stolen like this, to such an extent as to switchgear building transformer is repeatedly stolen, cause serious economic loss.
Summary of the invention
Technical matters to be solved by this invention is for the defect in above-mentioned background technology
,a kind of transformer anti-theft alarm is provided.
The present invention is for solving the problems of the technologies described above by the following technical solutions:
A transformer anti-theft alarm, this alarm comprises hummer, alarm lamp, emergency power pack and relay; Described relay pack is containing coil and switch, described hummer and alarm lamp are powered by emergency power pack, the switch series of described relay is connected in the current supply circuit of hummer and alarm lamp, described transformer is coil power supply, described transformer when being the coil power supply of relay relay in off state.
Preferably, described emergency power pack is battery.
Preferably, described battery is rechargeable battery.
Preferably, the power supply that described rechargeable battery is provided by transformer charges.
Adopt after such scheme, the invention has the beneficial effects as follows:
The invention provides a kind of transformer anti-theft alarm, after transformer frequency response is cut off, the normally closed contact of alarm relay is connected, and hummer and alarm lamp obtain electric alarm; Operator on duty can access the alarm of alarm, goes to scene to check, has effectively avoided the stolen of switchgear building transformer.
Accompanying drawing explanation
Fig. 1 is system architecture diagram of the present invention.
Embodiment
Below with reference to accompanying drawing, technical scheme of the present invention is elaborated.
Embodiment: as shown in Figure 1, a kind of transformer anti-theft alarm, this alarm comprises hummer, alarm lamp, emergency power pack and relay; Described relay pack is containing coil and switch, described hummer and alarm lamp are powered by emergency power pack, the switch series of described relay is connected in the current supply circuit of hummer and alarm lamp, described transformer is coil power supply, described transformer when being the coil power supply of relay relay in off state, described emergency power pack is battery, and described battery is chargeable storage, and the power supply that described rechargeable battery is provided by transformer charges.
During work, after transformer frequency response is cut off, the power supply of transformer loses the control to alarm relay coil, and then the closed-loop path energising of the switch of hummer, alarm lamp, emergency power pack and relay composition, and hummer and alarm lamp obtain electric alarm; Operator on duty hears the alarm of alarm, goes to scene to check, has effectively avoided transformer to be stolen.
Above embodiment only, for explanation technological thought of the present invention, can not limit protection scope of the present invention with this, every technological thought proposing according to the present invention, and any change of doing on technical scheme basis, within all falling into protection domain of the present invention.
