Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] To address the issue that traditional line inspection methods cannot accurately locate fault areas, thus hindering rapid line repair work; please refer to... Figure 1-2 The present invention provides the following solution:

[0019] A real-time alarm transmission line fault detection device includes a fault locator 1. The fault locator 1 includes a lower housing 101 and an upper housing 102. The lower housing 101 and the upper housing 102 are connected by screws. A photovoltaic panel groove 1021 is provided on the outer surface of the upper housing 102. A photovoltaic panel assembly 2 is provided inside the photovoltaic panel groove 1021. The photovoltaic panel assembly 2 is connected to the upper housing 102 by screws. An inner sleeve 3 is provided inside the lower housing 101 and the upper housing 102. The two ends of the inner sleeve 3 extend to the outer side of the housing, respectively.

[0020] In this embodiment, the device employs a dual-mode power supply design to ensure continuous operation. The photovoltaic panel module 2 converts solar energy into electrical energy, which is stored in a high-capacity lithium battery within the built-in power supply box 201. Even in cloudy or rainy weather or at night, the energy storage unit can ensure continuous operation for more than 72 hours. This self-powered mode eliminates dependence on external power sources and is suitable for outdoor overhead power line environments.

[0021] A magnet coil 104 is provided on the outside of the inner sleeve 3. Multiple sensor patches 302 are provided on the outer surface of the inner sleeve 3, and the sensor patches 302 are connected to the inner sleeve 3 through slots. An insulating limiting tube 103 is provided on the outside of the magnet coil 104. The insulating limiting tube 103 is connected to the lower housing 101 through a bracket. An internal power supply box 201 is provided on the inside of the photovoltaic panel assembly 2. The internal power supply box 201 is electrically connected to the sensor patches 302.

[0022] In this embodiment, when the power transmission cable passes through the inner bushing 3, the magnet coil 104 captures changes in the line current in real time through the principle of electromagnetic induction. The coil is made of a high-permeability magnetic material and has a sensitive response capability to microampere-level leakage current. The sensing patches 302 distributed on the surface of the inner bushing directly contact the outer insulation layer of the cable, collecting key parameters such as conductor temperature, mechanical vibration frequency, and insulation degradation. The collected data is analyzed in multiple dimensions by the built-in processor to effectively distinguish between temporary interference and real faults.

[0023] The inner sleeve 3 has a cable routing cavity 301 inside. Both ends of the inner sleeve 3 are provided with sleeve openings 303. A metal ring 3031 is provided on the inner side of the sleeve opening 303. The metal ring 3031 is connected to the sleeve opening 303 through a slot. A spring-loaded groove 3033 is provided on one side of the metal ring 3031. A rubber ring 3032 is provided inside the metal ring 3031.

[0024] In this embodiment, the cable enters from the closed side of the metal ring buckle 3031 and is pulled out to one side from the spring buckle groove 3033. After the cable enters, the spring buckle groove 3033 narrows, and the rubber ring 3032 is used to press and fix it. This can effectively prevent the device from shifting or sliding during installation and use.
