Detailed Description
The utility model will be further described in detail with reference to examples of embodiments shown in the drawings.
As shown in reference to figure 1 of the drawings,
a multipath power supply automatic detection and audible and visual alarm system comprises
An alarm 1 for giving an alarm;
a signal transmitter 2 for remotely transmitting alarm information;
the signal relay 3 is used for starting and stopping the alarm 1 to alarm;
the high-voltage vacuum circuit breakers 4 are used for supplying power to the electric equipment;
the number of the intermediate relays 5 corresponds to that of the high-voltage vacuum circuit breakers 4, and the power supply connecting end is connected with the switch end of the corresponding high-voltage vacuum circuit breaker 4; the two ends of the switch ends of the intermediate relays 5 which are sequentially connected in series are respectively connected to a live wire power supply and a coil end of the signal relay 3, and are connected to a zero line power supply through the coil end, and the two ends of the coil end are also connected to the two ends of the signal transmitter 2 in parallel;
the alarm 1 is connected to a live wire power supply through a switch end of the signal relay 3;
when any of the switches Duan Tiaozha of the high-voltage vacuum circuit breaker 4 is powered off, the coil end of the corresponding intermediate relay 5 is powered off, the coil end of the signal relay 3 is powered off, the alarm 1 gives an alarm, and the signal transmitter 2 gives alarm information.
When any one of the high-voltage vacuum circuit breakers 4 trips in the scheme, the corresponding switch part of the high-voltage vacuum circuit breaker 4 can be disconnected, at the moment, the corresponding intermediate relay 5 is disconnected, so that the switch part of the intermediate relay is disconnected, at the moment, the serial switch ends are disconnected, the coil of the signal relay 3 is disconnected, at the moment, the switch part of the signal relay 3 is reset, the alarm 1 can be electrified to give an alarm after the switch part is reset, and then an maintainer is prompted to overhaul, the alarm 1 can give an alarm after the signal relay 3 is disconnected according to different internal wiring structures, and can also give an alarm after the signal relay 3 is electrified. After the above-mentioned flow, because the signal transmitter 2 is originally connected to the power supply through the switch parts connected in series, at this time, one of the switch parts connected in series is disconnected, so that the power supply collected by the signal transmitter 2 is disconnected, the signal transmitter 2 can judge that the signal transmitter is in an alarm state at present, and then remotely send an alarm to an maintainer for maintenance.
Based on the effect of the multipath detection, the circuit can trip when any one circuit fails, and an alarm can be sent out, so that an maintainer can overhaul in time, and the highway can be restored to a normal operation state in time.
The switch end of the intermediate relay 5 after being connected in series is connected to a live wire power supply through a switch breaker, and the switch end of the signal relay 3 is connected to one end of the live wire. The switch breaker is used as a main switch, so that the power supply on-off of the circuit is more convenient.
In addition, signal indicator lamps 7 are connected in parallel to the two ends of the coil end of the intermediate relay 5. The signal indicator lamp 7 can make the maintainer at the total control position quickly know that the line has tripping faults, and the maintainer at the total control position conveniently and quickly goes to a fault point for maintenance.
The high-voltage vacuum circuit breaker 4 and the corresponding intermediate relay 5 are one group, and the number of the high-voltage vacuum circuit breaker and the corresponding intermediate relay 5 can be at least 5 groups, so that the multi-path line can be conveniently detected simultaneously.
The signal transmitter 2 may be associated with a sampling circuit, where the sampling circuit is configured to sample on/off of each intermediate relay 5, and when the signal transmitter 2 detects that a power failure occurs in a switch portion of the plurality of intermediate relays 5 connected in series, the sampling circuit starts to sample the intermediate relay 5 having the power failure, and record the number of the intermediate relay 5, and at this time, the number of the intermediate relay 5 may be also included when the signal transmitter 2 is able to transmit alarm information, so that the position of the fault point may be expressed. The remote sending of the signal transmitter 2 can adopt a GPRS module, and the GPRS module is used for sending in the form of telephone or short message, so that the overhauling personnel can be timely prompted.
Therefore, based on the scheme, when a single or multiple paths of power supply lines trip, local alarm and mobile phone end power-off alarm telephone notification can be realized, so that patrol personnel are helped to timely fail, the power utilization safety is ensured, and the manual patrol empty stop period is eliminated.
