[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0024] To address the issue of existing pole-mounted circuit breakers having complex external power supply structures and long-term exposure affecting their reliability during practical use, please refer to... Figures 1-4 This embodiment provides the following technical solution:

[0025] This embodiment of a deeply integrated pole-mounted circuit breaker with built-in power supply includes a circuit breaker housing 1. A protective cover 102 is embedded and connected to the front end of the circuit breaker housing 1. A switch module 3 is installed inside the protective cover 102. A power supply bracket 2 is provided below the switch module 3. The power supply bracket 2 includes:

[0026] The magnetic core coil 201 is located at the lower end of the switch module 3, and a loop wire 205 runs through the inside of the magnetic core coil 201. The built-in power supply is deeply integrated with the power supply bracket 2 set inside the pole-mounted circuit breaker. The power supply adopts the CT coil in Faraday's law. The power supply of the magnetic core coil 201 takes into account the electromagnetic conversion efficiency, insulation strength, mechanical stability and heat dissipation requirements.

[0027] The circuit breaker housing 1 has power terminals 101 at both the upper and lower ends. The power terminals 101 are used for inputting external power and outputting power. The circuit wires 205 are electrically connected to the power terminals 101 and the switch module 3, respectively. The lower end of the power take-up bracket 2 is equipped with a rectifier body 202, which is electrically connected to the magnetic core coil 201. An energy storage plate 203 is installed inside the rectifier body 202. The magnetic core coil 201 converts DC power into AC power by focusing the magnetic field of the conductor and introduces it into the energy storage plate 203. The power take-up of the magnetic core coil 201 takes into account electromagnetic conversion efficiency, insulation strength, mechanical stability and heat dissipation requirements. The magnetic core coil 201 does not consume active power from the circuit wires 205. Instead, it "captures" the electromagnetic energy dissipated around the circuit wires 205 through magnetic field coupling and collects it into AC power. The AC power is converted into pulsating DC power by the rectifier body 202. This does not hinder the operation of the circuit breaker and achieves built-in power take-up, maximizing energy efficiency and benefiting long-term operation.

[0028] In addition, a communication module 204 is installed below the power supply bracket 2. The communication module 204 is used to output circuit data to the server. The communication module 204 can send data information in a timely manner to realize remote monitoring.

[0029] In fact, the upper end of the switch module 3 is provided with a conductive line 301, which is electrically connected to the power terminal 101. The switch module 3 is provided with a shield 302 on the outside, which protects the switch module 3 and prevents the switch module 3 from being affected by the magnetic core coil 201 and the rectifier body 202.

[0030] Specifically, the built-in power supply is deeply integrated with the power supply bracket 2 inside the pole-mounted circuit breaker. It adopts the CT coil in Faraday's law to draw power. The power supply of the magnetic core coil 201 takes into account electromagnetic conversion efficiency, insulation strength, mechanical stability and heat dissipation requirements. The power supply of the magnetic core coil 201 does not consume active power from the circuit wire 205. Instead, it "captures" the electromagnetic energy dissipated around the circuit wire 205 through magnetic field coupling and collects it into alternating current. The alternating current is converted into pulsating direct current through the rectifier body 202. While not hindering the operation of the circuit breaker, it realizes built-in power supply, maximizes power efficiency and is conducive to long-term operation.

[0031] To address the problems of existing pole-mounted circuit breakers, such as their simple external housing structure, inconvenient maintenance and repair after pole mounting, and operational difficulties, please refer to... Figures 1-4 This embodiment provides the following technical solution:

[0032] In this embodiment, the upper end and the lower end of the protective cover 102 are both connected to the positioning sleeve 104 by fixing screws. Spring baffles 105 are installed inside the two positioning sleeves 104. A pressure spring is installed between the spring baffles 105 and the positioning sleeves 104. The protective cover 102 installed at the front end of the power supply deep integration pole-mounted circuit breaker protects the power supply bracket 2 and the switch module 3.

[0033] It should be noted that a magnetic suction plate 107 is provided at one end of the spring baffle 105. The upper and lower spring baffles 105 are connected by the magnetic suction plate 107. The positioning sleeves 104 at the upper and lower ends are used to clamp the two spring baffles 105. The spring baffles 105 are restricted by the magnetic suction plate 107 and the pressure spring, keeping the surfaces of the circuit breaker housing 1 and the protective cover 102 closed, which facilitates maintenance and repair work.

[0034] The circuit breaker housing 1 has a welding frame 106 installed at the rear end for fixing the utility pole, and a pole-mounted bracket 103 installed at the front end for fixing the utility pole. The pole-mounted bracket 103 is fixedly connected to the circuit breaker housing 1 by bolts. The circuit breaker housing 1 is installed on the utility pole by the pole-mounted bracket 103 and the welding frame 106 for switching operation.

[0035] Specifically, the protective cover 102 installed at the front end of the built-in power supply deeply integrated pole-mounted circuit breaker protects the power supply bracket 2 and the switch module 3. It uses positioning sleeves 104 at the upper and lower ends, which are clamped by two spring baffles 105. The spring baffles 105 are restricted by the magnetic suction plate 107 and the pressure spring, keeping the surface of the circuit breaker housing 1 and the protective cover 102 sealed, which facilitates maintenance and repair work and allows for long-term operation.

[0036] Working principle: During use, the circuit breaker housing 1 is mounted on the utility pole via the pole-mounted bracket 103 and welding frame 106 for switching operation. The switching module 3 is protected by the shielding cover 302 to prevent it from being affected by the magnetic core coil 201 and rectifier body 202. The internal power supply is deeply integrated with the power supply bracket 2 inside the pole-mounted circuit breaker, utilizing the CT coil based on Faraday's law. The power supply from the magnetic core coil 201 balances electromagnetic conversion efficiency, insulation strength, mechanical stability, and heat dissipation requirements. The power supply from the magnetic core coil 201 does not consume active power from the return wire 205. The electromagnetic energy dissipated around the field coupling "capture" circuit wire 205 is collected into alternating current. The alternating current is converted into pulsating direct current through the rectifier body 202. While not hindering the operation of the circuit breaker, it realizes built-in power extraction and maximizes power efficiency. The protective cover 102 protects the power extraction bracket 2 and the switch module 3. The positioning sleeves 104 at the upper and lower ends are clamped by two spring baffles 105. The spring baffles 105 are restricted by the magnetic suction plate 107 and the pressure spring, keeping the surface of the circuit breaker housing 1 and the protective cover 102 sealed, which facilitates maintenance and repair work and allows for long-term operation.
