Description of drawings
The structural representation of the feeder line fault automatic detection device that is used for electric power data acquisition system that Fig. 1 provides for the utility model embodiment.
Embodiment
The structural representation of the feeder line fault automatic detection device that is used for electric power data acquisition system that Fig. 1 provides for the utility model embodiment.As shown in Figure 1, present embodiment detection alarm device comprises testing circuit 10 and warning device 20, and wherein, whether testing circuit 10 is connected in series on the circuit in the electric system, interrupt for detection of circuit; Warning circuit 20 is connected with this testing circuit 10, is used for sending warning message when testing circuit 10 detects this line interruption fault.
Particularly, as shown in Figure 1, above-mentioned testing circuit 10 comprises first switch 11 and the relay 12 that is connected in series, and this relay 12 has first normally closed interlock 121; Above-mentioned warning circuit 20 comprises warning device 21 and the supply unit 22 that is connected in series, and warning circuit 20 is connected in series in the two ends of first normally closed interlock 121, wherein supply unit 22 is used to warning device 21 that power supply is provided, and warning device 21 is used for sending warning message when power supply.It will be appreciated by those skilled in the art that, during use, first switch 11 cuts out because relay 12 series connection on the line, when circuit just often, can be relay 12 power supply is provided, make first normally closed interlock 121 of relay 12 open, like this, warning circuit 20 will disconnect, supply unit 22 can't provide power supply for warning device 21, and warning device 21 just can't send warning message; When circuit interrupts for some reason, then can't provide power supply for relay 12, make first normally closed interlock 121 of relay 12 be in closed condition, at this moment, warning circuit 20 will conducting, and supply unit 22 can be warning device 21 power supply is provided, and warning device 21 will send warning message, this warning message can be collected by the electric power data acquisition system of disposing, to determine that power circuit breaks down.
In the present embodiment, when not needing to use this automatic detection alarm device, first switch 11 can be opened, at this moment, whether power network line just can be for relay 12 provide electric energy, like this, just can control this automatic detection alarm device and devote oneself to work by controlling first switch 11.
In the present embodiment, above-mentioned supply unit 22 specifically can be lithium battery or solar cell, preferably, can be solar cell, like this, can save the energy.
In the present embodiment, above-mentioned warning device 21 is specifically as follows hummer, like this, the sound that sends by hummer sends warning message, particularly, the warning message that this hummer sends can be collected by electric power data acquisition system, wherein can be provided with voice recognition device in the electric power data acquisition system, can identify length-specific that hummer sends or the warning message of frequency, to determine whether to occur feeder line fault.In addition, in the present embodiment, above-mentioned warning device 21 also can be radio communication device, it can be under "on" position, is used for sending prompting message to the customer center of electric power data acquisition system, for example short message etc., this customer center specifically can be a management platform with radio communication function, perhaps also can be a portable terminal, mobile phone terminal for example, user or maintainer can determine whether to occur line fault based on the short message that this customer center receives.
