Description

本实用新型属于电力线防盗报警领域。
经过查询,国内外没有发现与此相同的产品,国内其它类型的电力防盗报警器,主要缺点是只能应用于线路仃电状态。
本实用新型的目的,在于克服上述现有技术之不足,而提供一种在仃电和供电情况下均能防盗报警的新产品。
本实用新型的目的可通过以下措施来达到:
附图为本实用新型的实施例,下面结合附图的实施例说明如下:
本实用新型的主要特征在于由阻抗变换传感电路,比较驱动电路和报警电路组成。
如附图,A、B、C、O为四个接线柱,与三相电源电力线相接,T1、T2、T3为三只变压器,其初级分别为感抗电路,C1、C2、C3为容抗电路,T1、T2、T3初级感抗电路和C1、C2、C3容抗电路分别串联,使三相交流电压分别分压降压,组成隔交流通直流电路,使在电力线有电情况下,阻抗变换传感电路仍能构成直流通路而工作。另外T1次级给电源整流电路供电,并且T1、T2、T3次级接有指示灯ZD1、ZD2、ZD3,结合报警情况可显示各相仃电情况,或被盗情况。整流桥路、稳压集成块7806与R1、C4、C5等组成直流供电稳压电路,给本仪器供电,二极管D7、D8和电池E构成仃电直流电池供电电路。
阻抗变换传感电路,由提供的仪器外部附件反射器传感电阻R反1、R反2、R反3和仪器内的R2、R3、R4、R5、R6组成,传感电阻反射器接在仪器外要被保护电力线的远端,电力线的近端和仪器的A、B、C、O三相四线端子相连接,R反1、R反2、R反3分别通过二极管D1-D6的正向导通状态和串联的R5、R6相并联,然后再分别和R2、R3、R4限流电阻相串联后,再接直流供电电源。这样,当电力线被盗断开时,被盗这一支路的电阻到无穷大,R反1或R反2、R反3与R5、R6相并联的合电阻显著增大,使得限流电阻R2、R3、R4上流过的电流显著减小,压降也显著减小,则R5、R6上分得的电压显著增大,由R5、R6交点上取样得到这一显著增大的电压信号,即可得知电力线被盗,这样由此阻抗转换传感电路即可完成将电力线被盗的信号转换成电信号的输出。
从阻抗转换传感电路拾取的电信号送到比较驱动电路,比较驱动电路由基准电压电路R7、R8,运放或比较器IC1、晶体管BG1,与非门集成块IC2(也可由分离元件晶体管等构成)等组成。由阻抗转换传感电路送来的电信号与运放或比较器IC1的同相输入端3相连,R7和R8构成基准电压电路,将基准电压送入IC1的2端,当电力线被盗时,则由阻抗转换传感电路进入3端的取样电压信号将显著增高,必然显著高于基准电压信号,比较器翻转,IC1的1端由原先输出低电平,变为高电平,进而驱动BG1晶体管导通,BG1的集电极端电压降低,则IC2与非门的输出端获得驱动报警电路的高电平信号。
报警电路由ZD4报警灯(发光二极管或其它种类指示灯),和报警集成电路IC3(例如四声报警电路9561),驱动晶体管BG2、BG3,喇叭组成。比较驱动电路晶体管BG1的集电极通过负载电阻R10和报警灯ZD4相连,比较驱动电路的IC2与非门输出端与报警集成电路(例如四声报警电路9561)的触发端相连,报警集成电路的输出端与BG2、BG3驱动晶体管相连,进而连接喇叭。当电力线被盗时,比较驱动电路的BG1导通,集电极变低电平,报警指示灯亮,由灯光报警电力线被盗,同时,比较驱动电路的IC2与非门由平时的低电平变为高电平,触发驱动报警电路IC3,进而IC3输出,通过驱动晶体管BG2、BG3,驱动喇叭发出报警声,共同构成电力线被盗时,声光同时报警电路,使保卫人员及时赶到现场,处理和保卫电力线路的安全,本实用新型也可用于电器设备防盗报警。
本实用新型相比现有技术具有如下优点:
1、因其依赖线路的阻抗变换,与仃电供电状态无关,并设有隔交流通直流电路,所以供电和仃电情况下均能使用。
2、具有断相指示,所以便于鉴别断线或断电或何相被盗的不同情况。
3、工作时对附近电器无任何干扰。
本实用新型试验效果良好,已装成样机多台,具有实用推广价值。
