Abstract

The utility model provides an anti-theft alarming device of the field electric equipment. The 220V alternating current is switched into a transformer. The output end of the transformer is connected with a rectifier. The output end of the rectifier is connected with a direct current relay. The output end of the relay is respectively connected with a sound generator and a charging lamp. The alarming device according to the utility model begins to alarm when the transformer which is in the open and is observed by no man or the external line is switched off. The people can find the power-off problem no matter in daytime or night and inspect in time for avoiding the stealing of the transformer or external line. The charge for keeping the transformer and the external line is greatly saved. The loss of transformer or external line is prevented and the cost is reduced. The inner electric power source of the alarming device is a 12V charging lamp, and when the conditions of power-off, circuit breaking and the like occur, the inner electric power source can be directly taken for the field illumination.

Description

Open-air consumer burglar alarm

Technical field

The utility model relates to the burglar alarm technical field of open-air consumers such as transformer, outside line, particularly a kind of open-air consumer burglar alarm.

Background technology

The transformer inner core is done by copper, and open-air adopting with electric wire is made of aluminum or copper more, and copper, aluminium are rare metals, price is higher on the market, be the stolen principal element of transformer and outside line, and transformer is installed in the field mostly, it is big to keep an eye on difficulty in the production application, stolen easily.Transformer is antitheft at present, mainly adopts the mechanical consolidation mode, makes transformer be difficult at short notice being disassembled, and have certain anti-theft, but losing of transformer and outside line often occurs in night, if time enough is arranged, still stolen easily.

The utility model content

The purpose of this utility model is open-air just stolen in the unserviced transformer and the outside line of electricity consumption in order to prevent, adopts the principle of power alarm, provide a kind of anti-theft effect preferably, open-air consumer burglar alarm that can audio alert.

The purpose of this utility model is achieved through the following technical solutions:

A kind of open-air consumer burglar alarm, it is characterized in that the 220V alternating current is inserted transformer, output termination one rectifier of transformer, the output terminal of rectifier is connected with a DC relay, and the output terminal of relay is connected with speech synthesizer and rechargeable lamp respectively.

Described transformer output terminal connects an AC relay, and the output terminal of relay is connected with speech synthesizer and rechargeable lamp respectively.

Begin to report to the police when unserviced in the open air transformer of the utility model or outside line outage, no matter be daytime or night people can in time find the outage problem, inspection in time, in case transformer or outside line are stolen, greatly saved the expense of keeping an eye on of transformer and outside line, prevent losing of transformer or outside line, reduced loss.The internal electric source of this alarm is the 12V rechargeable lamp, if meet situations such as power failure, outage, can directly bring illumination when being used for field or power failure.

Fig. 3 is the circuit block diagram of the utility model embodiment 2;

Fig. 4 is the circuit theory diagrams of the utility model embodiment 2.

Embodiment

Below in conjunction with accompanying drawing the utility model is further elaborated:

The utility model can be formed mode by two kinds of circuit electronic component is connected, and embodiment 1 is first kind of mode:

With reference to Fig. 1, Fig. 2, the 220V alternating current becomes 12V or 6V electric current after 12V or 6V transformer transformation, inserts bridge rectifier, direct current through rectification inserts dull and stereotyped DC relay coil, and at this moment coil produces magnetic field, normally closed switch adhesive, make electric current enter rechargeable lamp, rechargeable lamp begins charging.After circuit disconnects, the relay coil no current by the time, at this moment relay coil does not form magnetic field, normally closed switch disconnects, normal open switch is opened simultaneously, make in the rechargeable lamp electric current often switch insert phonetic alarm, alarm begins sounding alarm.

Embodiment 2 is the second way:

With reference to Fig. 3, Fig. 4, the 220V alternating current is direct incoming transport relay coil after 12V or 6V transformer transformation, and at this moment coil produces magnetic field, the normally closed switch adhesive, and 12V or 6V electric current insert rechargeable lamp, make the rechargeable lamp charging; After circuit disconnected, the relay coil no current passed through, and at this moment relay coil does not form magnetic field, and normally closed switch disconnects, and normal open switch is opened simultaneously, make in the rechargeable lamp electric current often switch insert phonetic alarm, alarm begins sounding alarm.Among Fig. 3, Fig. 4,1,8 is the relay coil binding post, and 4,5 is the relay normally open switch columm, and 2,7 is relay normally closed switch binding post, and 3,6 is relay intermediate switch binding post.

Embodiment 1 and 2 difference be, embodiment 1 be with the 220V alternating current through the 12V after the transformation (or 6V) alternating current after rectification.Become direct current, insert DC relay again and start working.DC relay heating or vibrations have been avoided.Embodiment 2 is with 12V (or 6V) the alternating current direct incoming transport relay of 220V alternating current after transformation, and relay is started working, and adopts this mode circuit simpler, and cost is low.

Claims

1, a kind of open-air consumer burglar alarm, it is characterized in that the 220V alternating current is inserted transformer, output termination one rectifier of transformer, the output terminal of rectifier is connected with a DC relay, and the output terminal of relay is connected with rechargeable lamp and speech synthesizer respectively.

2, open-air consumer burglar alarm according to claim 1 is characterized in that described transformer output terminal connects an AC relay, and the output terminal of relay is connected with speech synthesizer and rechargeable lamp respectively.

3, open-air consumer burglar alarm according to claim 1 and 2 is characterized in that it is one the tunnel that described rechargeable lamp and relay normally closed switch connect, and it is one the tunnel that described phonetic alarm and relay normally open switch connect.
