Abstract
An anti-theft electric meter is composed of casing, rotary disk in the casing, electric consumption indicator, joint, voltage coil, current coil, relay, reverse-rotation preventer and sound-light alarm. When the electricity thief steals electricity by a common method, the contact of the relay is connected with the alarm device to send out alarm sound and light signals. It is characterized in that: the intelligent alarm has the advantages that the electricity stealing prevention is reliable and visual, the alarm is audible and visual, the alarm is easy to discover, and the alarm can generate a wonderful effect that the heart is weak and the alarm is afraid of being forgotten; secondly, simple structure, it is easy to make, with low costs, but the usable shell, carousel, power consumption display of existing, just reform transform the circuit.
Description
The utility model relates to the ammeter new varieties.
With reference to the accompanying drawings, existing meter circuit only is made up of potential winding (L) and current coil (1), and this ammeter can be stolen easily, its means: the one, joint (1) and (2) line are disconnected, the ammeter rotating disk does not then change, and in the same old way to electric stealer's transmission of electricity, and electricity consumption shows that number does not increase; The 2nd, incoming line (1) and output line (3) changing-over, then ammeter rotating disk counter-rotating, the electric stealer is electricity consumption in the same old way, and electricity consumption shows that number reduces on the contrary.
The purpose of this utility model is to provide the above-mentioned means of a kind of usefulness can't steal the Theft-proof kilowatt-hour meter of electricity.
The utility model is to adopt the former ammeter circuit to be transformed the mode that promptly installs two relays, two cover sound, light warning device, anti-ammeter rotating disk inverter additional and change the method for attachment of circuit to achieve the goal.As electric stealer during with above-mentioned first kind of means, a relay job, a cover warning device is reported to the police, and electricity output is arranged, but rotating disk changes.During with second kind of means, inverter makes another relay work, does not have electricity output, and rotating disk does not reverse simultaneously, and another set of warning device is reported to the police.
The utility model characteristics: the one, antitheft electricity is reliable, directly perceived, sound, light is reported to the police, and easily finds, can produce the prestige of having a guilty conscience and dare not act recklessly to the electric stealer and take the photograph effect; The 2nd, simple in structure, easy to manufacture, cost is low, can utilize shell, rotating disk, the power consumption display of existing ammeter, and only circuit be improved.
Below in conjunction with accompanying drawing embodiment is described:
Accompanying drawing is this meter circuit synoptic diagram.
With reference to accompanying drawing, this ammeter is by shell (E) and be contained in rotating disk in the shell, power consumption display, joint (1,2,3,4,5), potential winding (L), current coil (l), relay (G, J), (P
