Fig. 2 is the module map of embodiment of the present invention lightning arrester.
Fig. 3 is the module map of embodiment of the present invention control device.
Detailed description of the invention
Below, in conjunction with example, substantive distinguishing features of the present invention and advantage are further described, butThe present invention is not limited to listed embodiment.
Refer to Fig. 1~3, the lightning arrester of the present embodiment, comprises at least one lightning rod 10, extremelyA few drop bar 30 and control device, between described lightning rod 10 and drop bar 30 by leadingLine 20 connects, and described lightning arrester also comprises monitoring device 100 and auxiliary earthing apparatus 300,Monitoring device 100 is electrically connected by wire 101 with lightning rod 10, described auxiliary earth 300Device is embedded in the earth, and monitoring device 100 passes through wire 102 with auxiliary earthing apparatus 300Electrical connection, described monitoring device comprises measuring unit 120 and power supply unit 110, measuring unit120 comprise processor circuit 123, and direct current is delivered current circuit 121 and operational amplification circuit 122,Described direct current delivers current circuit 121 and operational amplification circuit 122 is connected on lightning rod 10 and auxiliaryBetween earthing or grounding means 300, described power supply unit 110 is connected with measuring unit 120. Each is kept awayThe release way of thunder pin 10 is monitored by a monitoring device 100, and its monitoring target justIt is the loop as shown in phantom in FIG. including release way. Described loop is from monitoring device100, through wire 101, lightning rod 10, wire 20, drop bar 30, then enter the earth,Again by the earth, through auxiliary earthing apparatus 300, wire 102, then get back to monitoring device 100.
When having the time of opening circuit in the release way that lightning rod 10, wire 20, drop bar 30 form, onState loop and just there will be abnormal electrical resistance, monitoring device 100 judges release by described resistance valueWhether path is normal.
In order to save electric power, described processor circuit 123 be according to the triggering of control device 200 orBe itself periodically to start direct current conversion alternating current circuit 121, what power supply unit 110 was provided is straightStream electric power is converted to the electric current and voltage of interchange, and the electric current and voltage of this interchange is put on loop.
