Brief description of the drawings
Fig. 1 is the circuit diagram that siganl thunder-proof device of the present invention is realized the deteriorated Real-time Alarm function of remote signalling.
Detailed description of the invention
Below with reference to accompanying drawing, the present invention is given to elaboration further.
Refer to Fig. 1, a kind of siganl thunder-proof device provided by the invention comprises an interface CON2, this interfaceCON2 has a remote signalling input J1 and a remote signalling output J2, exports a remote signalling for siganl thunder-proof deviceSignal. This interface CON2 can be RJ45 interface, RS485 interface, RS232 interface or DB09Any one of interface, also can with the remote signalling interface tandem that possesses hot dropout principle, practical function expand.
This siganl thunder-proof device also comprises an induction coil L2 and a warning circuit, and this induction coil L2 canFor ring current induction coil. One end of induction coil L2 is connected with remote signalling input J1, the other end withOne end of warning circuit connects, and the other end of warning circuit is connected with remote signalling output J2. Wherein, alarmCircuit also comprises again one first circuit and the second circuit in parallel with this first circuit, in normal operating conditionsTime, the first circuit pathways, second circuit open circuit; In the time of deterioration state, the first circuit breaker, the second electricityRoad is high impedance status.
Particularly, the first circuit comprises a protective tube F1, second circuit comprise one second resistance R 2 and withThe one second transient diode D2 that the second resistance R 2 is connected. Wherein, protective tube F1 is little current insurancePipe, current value is 63mA, for example fast fusing type fuse. The second resistance R 2 is high resistance measurement, electricityResistance is 330K-1M ohm. The voltage range of the second transient diode D2 depends on interface CON2Remote signalling voltage range. In the time of normal operating conditions, protective tube F1 is by the second resistance R 2 and the second transient stateDiode D2 bypass, makes remote signalling output J2, protective tube F1, induction coil L2 and remote signalling inputEnd J1 forms electric loop, and from interface CON2, this electric loop is short-circuit condition; At deterioration stateTime, because thunder-strike current exceeds standard, for example thunder-strike current is greater than maximum nominal current or thunder-strike current is greater than70% of maximum nominal current, the induced-current that induction coil L2 produces will cause protective tube F1 to be fused,The state of interface CON2 is changed, from interface CON2, comprise remote signalling output J2,The second transient diode D2, the second resistance R 2, induction coil L2 and remote signalling input J1 electric timeRoad is open-circuit condition.
Further, siganl thunder-proof device also comprises one the 3rd resistance R 3, one first resistance R 1 and one firstTransient diode D1. Wherein, the 3rd resistance R 3 and the first resistance R 1 are little resistance resistance, resistanceValue is 3.3-10 ohm. The voltage range of the first transient diode D1 depends on that interface CON2's is distantLetter voltage range. The 3rd resistance R 3 is connected between remote signalling input J1 and induction coil L2, and firstResistance R 1 is connected between warning circuit and remote signalling output J2, for eliminating under instantaneous thunder-strike currentRemote signalling input J1 is to the coupling of remote signalling output J2, and protection interface CON2, simultaneously due to the 3rd electricityResistance R3 and the first resistance R 1 are little resistance resistance, are short circuit or open-circuit condition not for interface CON2Can exert an influence. One end of the first transient diode D1 is connected in the 3rd resistance R 3 and induction coil L2Between, the other end is connected between warning circuit and the first resistance R 1, so that remote signalling input J1 and distantBelieve the clamping action due to this first transient diode D1 between output J2, and there will not be too highTerminal voltage ensures that the voltage of interface CON2 is in a constant scope, simultaneously for induction coil L2 producesRaw induced-current provides loop, to reduce the induced-current shunting of remote signalling input J1.
In a preferred embodiment, in the time of normal operating conditions, because the second resistance R 2 is 510K ohmHigh resistance measurement, the ON time of the second transient diode D2 is delayed, also reduce simultaneouslyThe On current of the second transient diode D2, thereby adjusting is flowed through, the electric current of protective tube F1, makes insurancePipe F1 can be by the second resistance R 2 and the second transient diode D2 bypass, i.e. the first circuit pathways, secondCircuit is under low pressure open circuit, so make remote signalling output J2, the first resistance R 1, protective tube F1,Induction coil L2, the 3rd resistance R 3 and remote signalling input J1 form electric loop, from interface CON2See, this electric loop is short-circuit condition. In the time of deterioration state, because thunder-strike current exceeds standard, i.e. thunderbolt electricityStream is greater than 70% of maximum nominal current, and the induced-current that induction coil L2 produces will cause protective tube F1Fused, i.e. the first circuit breaker, the induced-current second circuit of flowing through, make remote signalling output J2,The first resistance R 1, the second transient diode D2, the second resistance R 2, induction coil L2 and the 3rd resistanceR3 forms electric loop, and due to the clamping action of the second transient diode D2, second circuit under low pressureCan be high impedance status, this electric loop is interdicted by the second transient diode D2, therefore, and from interfaceCON2 sees, this electric loop is open-circuit condition. Meanwhile, the external low-voltage monitoring electricity of interface CON2Road also keeps open-circuit condition. Real-time Alarm when this remote signalling is deteriorated, makes this siganl thunder-proof device bad in appearanceIn situation about changing, by the size of the real-time indirect lightning strike electric current of induction coil, can be in time by interfaceState changes to open-circuit condition by short-circuit condition, and this state cannot reverse, thereby safeguards in device contextAspect has certain superiority.
In sum, a kind of siganl thunder-proof device of the present invention is realized the deteriorated reality of remote signalling by warning circuit is setTime alarm function, the personnel of maintaining easily carry out safety inspection and the maintenance of siganl thunder-proof device, not only cabling letterSingle, do not need power supply to power, conveniently carry out the monitoring of remote signal lightning protection device deterioration state, andApply electromagnetic induction principle and do not possess electrical connection with main protection circuit, distant with isolation method outputLetter signal and can not have any interference to original siganl thunder-proof device interlock circuit, has improved security and canBy property, and volume is little, possesses good structure compatibility, can compatible most of siganl thunder-proof deviceShell, practical function is expanded.
Foregoing, is only preferred embodiment of the present invention, not for limiting embodiment of the present invention,Those of ordinary skill in the art, according to main design of the present invention and spirit, can carry out phase very easilyFlexible or the amendment of answering, thus protection scope of the present invention should taking the desired protection domain of claims asAccurate.
