Embodiment
Referring to shown in Fig. 1 to Fig. 4, the technical program is described in detail.
Specific embodiment:
A kind of intelligent electric meter anti-electricity-theft device, comprise ammeter box 1, touch switch 2, controller 3, intelligent electric meter 4, line of electric force 5, box plate 7, ammeter lower plate 8, arc lock unit 6 is provided with in described ammeter box 1, when the door of ammeter box 1 is closed, the contact arm of described touch switch 2 contacts with the inside surface of the door of ammeter box 1, described arc lock unit 6 comprise to be connected with intelligent electric meter 4 leading-out terminal and with the ammeter gland 9 of ammeter lower plate 8 Joint, with the base plate gland 10 of box plate 7 Joint, with the active lock housing 11 of lock core 18, with the passive lock housing 12 that active lock housing 11 is supporting, described line of electric force 5 is through described ammeter gland 9 and base plate gland 10, described active lock housing 11, be provided with in passive lock housing 12 and described ammeter gland 9, the head recess 13 that base plate gland 10 is supporting, with the inner recess 17 that line of electric force 5 is supporting, the Fixed latches 15 supporting with the spliced eye 14 that arranges in ammeter gland 9 and base plate gland 10 is provided with in described head recess 13, passive lock housing 12 is provided with passive latch 16, initiatively in lock housing 11, the position supporting with passive latch 16 is provided with passive jack 17, be provided with the fixing snap of passive jack in described passive jack 17, initiatively lock housing 11 and passive lock housing 12 opposite position are provided with solenoid and armature 63, described solenoid is connected with controller 3 by control line, described snap is connected with lock core 18, power supply 31 is provided with in described controller 3, control center's unit 32, Carrier 33, described touch switch 2 is connected with control center unit 32 by control line, described arc lock unit 6 is connected with control center unit 32 by control line, described control center unit 32 is connected with power supply 31 by control line, described control center unit 32 is connected with intelligent electric meter 4 by control line.The part that described arc lock unit 6 is connected with ammeter gland 9, base plate gland 10 is line part 61, and two line parts 61 are connected by arc sections 62.Described two line parts 61 and arc sections 62 are equipped with passive latch 16.Described solenoid and armature 63 are arranged on line part 61.Described controller 3 is provided with numeric keypad, and described numeric keypad is connected with control center unit 32.Described power supply 31 is nickel-cadmium battery.
Workflow of the present invention is as follows: when normal operators carries out casing attended operation, need to open ammeter box 1, at this moment the inside surface of the contact arm of touch switch 2 and the door of ammeter box 1 sends and slides or depart from, touch switch 2 sends electric signal and enters control center's unit 32 by control line, after Carrier 33 carrier wave by wire transfer to long-range control center, remind flexecutive watch authorization conditions.If the plan now not having normal operators to operate or record, be then electricity filching behavior, notify that related personnel watches to scene or checks in time.
When normal operators needs to safeguard the line of electric force 5 be connected with intelligent electric meter 4, need to do two step work, control line between first closing controller 3 and arc lock unit 6, make solenoid power-off, the suction-combining force between solenoid and armature 63 is disappeared, secondary need uses key rotation lock core 18, make the disengaging between the snap of setting in passive jack and passive latch 16, then initiatively lock housing 11 and passive lock housing 12 is made, ammeter gland 9, base plate gland 10 is separated, and take off ammeter gland 9, after base plate gland 10, attended operation can be carried out to line of electric force 5.In this process, the action of cutting-off controlling line is typically administered remotely personnel equally and monitors.
When there is the accidents such as abnormal power-down, owing to being provided with independent current source 31 in controller 3, under the support of power supply 31, solenoid still can work.Even if power-off time is longer, the electricity of power supply 31 exhausts, and arc lock unit 6 still mechanically, can pin passive latch 16 by snap, makes stealing personnel can not open arc lock unit 6 easily, for electric power personnel inspection gains time.
In addition, in controller 3, by the Carrier 33 in it, charge condition of intelligent electric meter 4 can be sent to flexecutive in good time, as user power utilization amount there is abnormal variation time, electric power personnel also can be reminded to check.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For the those of ordinary skill belonging to the present invention, under the prerequisite not departing from thinking of the present invention, simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
