Description

Technical Field

[0001] This utility model relates to the field of circuit breakers, specifically a solid-sealed pole of a circuit breaker. Background Technology

[0002] Under the global trend of energy transition, traditional power grids are facing unprecedented challenges. With the large-scale integration of distributed energy sources such as solar and wind power, the intermittency and volatility of their power generation have a significant impact on the stability and reliability of the power grid. At the same time, users' requirements for the quality and stability of power supply are increasing, and the limitations of traditional power grids in data processing, fault diagnosis, and energy management are becoming increasingly apparent.

[0003] Currently, circuit breakers cannot monitor parameters other than current and voltage in real time, such as temperature or arc data, and cannot respond quickly to circuit breaker faults, resulting in untimely fault handling. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

The top of the insulating cylinder is provided with an inlet post, and the side end of the insulating cylinder is provided with an outlet post. The outlet post is connected to a conductive rod. A temperature probe is sleeved on the conductive rod. A temperature sensor, a zero-sequence voltage sensor, and a power-collecting capacitor are provided inside the insulating cylinder. A conductive ring is sleeved below the inlet post. The temperature sensor, zero-sequence voltage sensor, and power-collecting capacitor inside the insulating cylinder are connected in parallel to the conductive ring via wires.

[0007] In one possible implementation, a current inductance winding is provided on one side of the zero-sequence voltage sensor, and the current inductance winding is sleeved on the conductive rod.

[0010] In one possible implementation, the temperature probe is a fluorescent fiber optic temperature probe, and the temperature sensor is a grating temperature sensor.

[0011] In a second aspect, a circuit breaker includes the aforementioned solid-sealed pole and edge computing module, wherein the solid-sealed pole is placed outside the enclosure, the edge computing module is placed inside the enclosure, and the solid-sealed pole is connected to the edge computing module via a signal line.

[0012] In one possible implementation, the temperature probe is connected to the temperature rise interface on the edge computing module via a signal line, the zero-sequence voltage sensor is connected to the zero-sequence voltage interface on the edge computing module, and the power-collecting capacitor is connected to the power-collecting interface on the edge computing module.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. By installing temperature sensors, zero-sequence voltage sensors, and power-collecting capacitors in parallel inside the insulating sleeve, the structure is compact, which is conducive to heat dissipation and can collect data from the solid-sealed pole in a timely manner.

[0015] 2. By monitoring the temperature of different parts of the solid-sealed pole through temperature sensors and temperature probes, faults caused by abnormal temperature of the circuit breaker can be detected in a timely manner, which facilitates rapid calculation and response by the edge computing module.
