Description
Technical field
The utility model relates to electric power utility appliance, relates in particular to a kind of pole transformer anti-theft module.
Background technology
At present, because pole transformer is widely used, there is again larger economic worth simultaneously, often become the object of lawless person's theft, transformer is stolen not only causes larger economic loss, bring very big interference also to the normal productive life of vast power consumer, this be there is no to effective technological prevention means yet.Recent years, wireless load measuring-recording instrument has all been installed in a lot of distribution transformings, can regularly detect distribution transformer load situation, yet but cannot react for other physical parameters of the normal operation of reflection transformer, does not also possess antitheft function.Existing burglar alarm means utilization vibration or displacement transducer, cost is higher, and failure rate is high, easily malfunction disturbs residents, therefore, develop and a kind ofly can effectively prevent pole transformer theft, reliability anti-theft technique high, with low cost simultaneously, become those skilled in the art's problem demanding prompt solution.
Summary of the invention
The purpose of this utility model is to provide a kind of pole transformer anti-theft module, is equipped with back-up source, has self-sustaining warning function; Meanwhile, compare the mode that tradition adopts vibrations or displacement transducer, there is high reliability and advantage cheaply.
The technical scheme that realizes above-mentioned purpose is:
A pole transformer anti-theft module, comprising: power module, backup battery, resistance, be wrapped in signal wire, thyristor, reset and testing button, signal output part and alarming horn on transformer, wherein:
Described power module, resistance and signal wire are connected successively and are formed loop;
The positive pole of described thyristor connects the end that joins of described power module and resistance, and negative pole connects described signal output part, and gate pole connects the end that joins of described resistance and signal wire;
Described reset is connected the positive pole of described thyristor with one end of testing button, the other end connects the negative pole of described thyristor;
Described alarming horn one end connects described signal output part, and the other end connects the end that joins of described signal wire and power module;
Described backup battery is in parallel with power module.
In above-mentioned pole transformer anti-theft module, the positive pole of described power module and described resistance join; The positive pole of described backup battery and the positive pole of described power module join, and the negative pole of described backup battery and the negative pole of described power module join.
The beneficial effects of the utility model are: the utility model adopts unique broken string self-sustaining warning circuit, once detection line is broken in transformer displacement, just can send immediately chimes of doom and draw back robber with fear, because this circuit is equipped with backup battery, even therefore burglar cut off the electricity supply, again connect signal wire reports to the police also not can involution, in the time of warning, can also connect teletransmission equipment by signal output part and post a letter to Surveillance center.Meanwhile, owing to not adopting vibrations or displacement transducer, its reliability is high, with low cost, and can malfunction not disturb residents.
Accompanying drawing explanation
Fig. 1 is the circuit theory diagrams of pole transformer anti-theft module of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1, pole transformer anti-theft module of the present utility model, comprising: power module T, backup battery B, resistance R 1, signal wire L, thyristor V1, reset and testing button K, signal output part O and alarming horn S, wherein:
Power module T, resistance R 1 and signal wire L connect successively and form loop;
The positive pole of thyristor V1 connects the end that joins (that is: the positive pole of power module T) of power module T and resistance R 1, and negative pole connects signal output part O, the end that joins of gate pole contact resistance R1 and signal wire L;
Reset and be connected the positive pole of thyristor V1 with one end of testing button K, the other end connects the negative pole of thyristor V1;
Alarming horn S one end connects signal output part O, and the other end connects the end that joins of signal wire L and power module T;
Backup battery B and power module T in parallel in the same way (that is: anodal is connected anodal, negative pole connection negative pole), after parallel connection for whole module provides DC supply;
Resistance R 1 is connected with signal wire L, when normal, signal wire L is wrapped on transformer body, once transformer is stolen, signal wire L must be pulled off, and positive supply triggers thyristor V1 conducting by R1, and after thyristor V1 conducting, alarming horn S sends high-decibel chimes of doom to draw back robber with fear, now signal output part O becomes high level, this termination can be entered to load measuring-recording instrument or other wireless on-line monitoring devices, by it, post a letter to Surveillance center, remind transformer stolen.Once after thyristor V1 triggering and conducting, even if robber recovers connection signal line L, report to the police and also can not stop; Whether if robber cuts off the electricity supply, backup battery B can continue to provide the required power supply of reporting to the police, and only presses and resets and testing button K ability stop alarm, also can press at ordinary times this button and come judge module working properly.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, in the situation that not departing from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
