Detailed Description
The present invention will be described in further detail with reference to the following detailed description and accompanying drawings.
An embodiment of the present invention provides an enhanced power carrier signal sensor, as shown in fig. 1, including a lightning protection colloid 12, a mounting bracket 13, a detacher 14, and a fixing head 15. The surface of lightning protection colloid 12 is equipped with a plurality of canopy 121 along the coaxial distribution of lightning protection colloid extending direction, and canopy 121 includes first canopy and the second canopy of radius difference, and first canopy and second canopy set up at an interval each other, can promote the lightning protection effect. The top end of the lightning protection colloid 12 is provided with a connector lug 11, and a through hole for a lead to pass through is arranged in the lightning protection colloid 12. During detection, the connector lug 11 can be connected with a cable, and the cable is connected to a line to be detected, so that a carrier signal on the line to be detected can be switched into the sensor of the embodiment. The bottom end of the lightning protection colloid 12 is sleeved with the mounting bracket 13, and the mounting bracket 13 is mounted on an electric power tower or a telegraph pole. The two ends of the disconnector 14 are respectively connected to the lightning protection colloid 12 and the fixed head 15, the bottom end of the fixed head 15 is provided with a signal connector 206 and a ground connector 208, and the ground connector 208 is used for grounding. Wherein, the detacher 14 can be a thermal explosion type detacher. A plurality of reinforcing plates 131 arranged in parallel are sleeved on the mounting bracket 13 to enhance the structural strength of the mounting bracket 13.
A processing circuit is arranged in the fixed head 15, and the processing circuit comprises a PLC signal processor 203, a magnetic core inductor 204 and an anti-explosion cap 205. A high-voltage capacitor 103 is arranged in the lightning protection colloid 12. As shown in fig. 2, the connector lug 11, the high-voltage capacitor 103, the disconnector 14, the PLC signal processor 203, the detonator 205 and the ground connector 208 are sequentially connected, the magnetic core inductor 204 is respectively connected to two ends of the PLC signal processor 203, the ground connector 208 is further connected to one end of the magnetic core inductor 204, and the other end of the magnetic core inductor 204 is connected to the signal connector 206. The carrier signal of the line to be detected, which is accessed by the connector lug 11, is accessed to the sensor, and the carrier signal of the line to be detected is coupled through the PLC signal processor 203 and the high-frequency magnetic core inductor 204, and is finally output to the relevant detection equipment through the signal connector 206. Because the connector lug 11 directly contacts with the line to be detected, the signal is directly transmitted to the sensor, the transmission distance of the signal connector 206 to the signal is longer, the transmission speed is higher, and the communication performance of the sensor is improved.
The high voltage capacitor 103 is used for filtering the original signal. The disconnector 14 can automatically fall off under a high-voltage and high-current state, and the anti-detonator 205 is instantly broken after lightning stroke, so that the anti-detonator has a lightning protection function to protect the sensor from the lightning stroke.

Further, a waterproof cap 105 is further sleeved on the guide rod 106, and the second connector 104 and the mounting bracket 13 are used for clamping and fixing the waterproof cap 105 so as to prevent water from contacting with the guide rod 106 and improve the safety of the guide rod 106.
In one embodiment, the fixed head 15 includes a housing 151 and a cover plate 207 covering the housing 151, a circuit board 202 is disposed in the housing 151, the PLC signal processor 203, the magnetic core inductor 204 and the anti-detonation cap 205 are all fixed on the circuit board 202, and corresponding leads are naturally disposed on the circuit board 202 to connect the PLC signal processor 203, the magnetic core inductor 204 and the anti-detonation cap 205. Wherein one end of the signal connector 206 is fixed on the circuit board 202, and the other end extends from the cover plate 207 and thus extends out of the fixing head 15, and one end of the ground connector 208 is also fixed on the circuit board 202, and the other end extends out of the fixing head 15.
A connecting rod 201 is further arranged in the fixing head 15, one end of the connecting rod 201 is fixed on the circuit board 202, and the other end of the connecting rod 201 is connected with the detacher 14. When the detacher 14 is disengaged, the carrier signal will no longer be received by the fixed head 15. Wherein, the signal connector 206 can be a TNC connector.
