Abstract
The utility model discloses an anti-theft alarm of electric power circuitry. The anti-theft alarm connects the coils of three intermediate relays in parallel between each fire line and zero line; one pair of permanent closed contacts of each relay connected in parallel is concatenated in an alarm lop. The anti-theft alarm of electric power circuitry provided by the utility model with simple structure, reliable performance and good anti-theft performance can prevent the electric power from stealing and effectively guarantee the safe operation of electric network.
Description
The utility model relates to a kind of burglar alarm of power circuit.
Along with rural power grids are constantly newly-built and universal, bring great benefit to vast farmers.But, under individual interest drives, will steal the approach that electric power facility " is built up a family fortune and controlled richness " as them because a few peoples are very weak in the understanding of law.Electric wire and the stolen incident of substation transformer take place in many in recent years places repeatedly, cause power circuit to interrupt, and bring massive losses for country and society.And this case is at present also in rising trend.Therefore power department presses for a kind of power circuit anti-theft device and ensures that the power circuit conveying is unimpeded.
The purpose of this utility model is to avoid the appearance of above-mentioned phenomenon, and a kind of simple in structure, dependable performance is provided, is convenient to operation, and theftproof performance is good, can ensure effectively that power circuit carries unimpeded circuit anti-theft device.
The purpose of this utility model reaches by following technical measures: this circuit anti-theft device is made up of auxiliary reclay, voice guard, alarm call and lead.The electricity circle of each auxiliary reclay in parallel respectively between every phase firewire of line of electric force three-phase firewire and zero line wherein, and after these three auxiliary reclays a pair of normally closed contact separately is connected in parallel, be serially connected in again in the operation circuit that constitutes by voice guard and alarm call.
Accompanying drawing is a circuit diagram of the present utility model.
The utility model is described in further detail below in conjunction with embodiment: this anti-theft device is made up of three auxiliary reclays (1,2,3), voice guard (4), alarm call (5) and lead (6).With these three auxiliary reclays (1,2,3) coil separately respectively with three-phase firewire in every phase firewire and zero line be in parallel.And then with these three auxiliary reclays (1,2,3) separately a pair of normally closed contact be in parallel after, be serially connected in together again in the operation circuit that constitutes by voice guard (4) and alarm call (5).
This burglar alarm is work like this: when line of electric force is in safe normal condition, the electricity circle of each auxiliary reclay all can get, therefore the armature of auxiliary reclay is held, the normally closed contact of auxiliary reclay disconnects, so the operation circuit of alarm and alarm call is disconnected, so the operation circuit of audible alarm and alarm call is disconnected, and does not have warning message to send, show that power circuit is in a safe condition.In case the burglar cuts off arbitrary phase electric wire of line of electric force, then the coil of that auxiliary reclay that this phase line connect is understood dead electricity, and causes the armature of auxiliary reclay to be released, and makes its normally closed contact closure.So the loop of voice guard and alarm call is connected automatically, can send chimes of doom on the one hand, allow line attendant responding immediately safeguard power circuit; The fixed line phone that can also allow alarm call start mobile phone, the beeper that sets and bring electricity to show is on the other hand reported to the police to responsible person at a distance.
The utility model has following advantage compared to existing technology: this burglar alarm is simple in structure, Convenient operation, dependable performance have good theftproof performance, can stop the stolen event of power line Generation, thereby guaranteed the safe operation of electrical network.
Claims (1)
1, a kind of power circuit burglar alarm of forming by three auxiliary reclays (1,2,3), voice guard (4), alarm call (5) and lead (6), it is characterized in that between every phase firewire of line of electric force three-phase firewire and zero line the coil of each auxiliary reclay in parallel (1,2,3) respectively, and after these three auxiliary reclays (1,2,3) a pair of normally closed contact separately is connected in parallel, be serially connected in again in the operation circuit that constitutes by sound newspaper device and alarm call.
