Description

Technical Field

[0001] This utility model relates to a distribution box, and more particularly to an intelligent distribution box with fault arc detection, belonging to the field of distribution box technology. Background Technology

[0002] Distribution boxes are an important component of power systems, primarily used for the distribution, control, and protection of electrical energy. As a critical node in electrical equipment, distribution boxes, through internal components such as switches, circuit breakers, and fuses, safely and reliably distribute electrical energy to various electrical devices or circuits. They not only enable the connection and disconnection of power lines but also quickly cut off power in the event of overloads, short circuits, or other faults, preventing the fault from escalating and protecting the safety of personnel and equipment.

[0003] Fault arc is a gas ionization discharge phenomenon caused by air breakdown due to reasons such as insulation aging and damage, loose electrical connections, humid air, and a sharp increase in voltage and current in electrical lines or equipment. When fault arc is generated, its high temperature and heat can easily ignite the insulation layer of the line and cause the line to catch fire. Therefore, an intelligent distribution box with fault arc detection is proposed. Utility Model Content

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1-4 As shown, this utility model embodiment provides an intelligent distribution box with fault arc detection, including a box door assembly 20. The box door assembly 20 includes a door body 21, a control panel 23, an audible and visual alarm 26, a support plate 27, a drive motor 28, a threaded rod 29, a guide rod 210, a lifting seat 211, an ultraviolet light sensor 212, an ultrasonic sensor 213, and an infrared imager 214.

[0028] A control panel 23 is installed on the front surface of the door 21, and an audible and visual alarm 26 is also installed on the front surface of the door 21. A support plate 27 is fixedly connected to the inner side wall of the door 21. A drive motor 28 is installed at the bottom of the support plate 27. The output shaft of the drive motor 28 is fixedly connected to one end of a threaded rod 29. The threaded rod 29 is rotatably connected to the top of the support plate 27. A guide rod 210 is fixedly connected to the top of the support plate 27. A lifting seat 211 is threadedly connected to the outer side wall of the threaded rod 29. The lifting seat 211 is slidably connected to the outer side wall of the guide rod 210. An ultraviolet light sensor 212, an ultrasonic sensor 213, and an infrared imager 214 are installed on the rear surface of the lifting seat 211. Due to the limited space inside the distribution box, the image distance of the infrared imager 214 is short and the shooting area is small. This utility model uses the drive motor 28 to drive the threaded rod 29 to rotate, changing the position of the lifting seat 211, and using the infrared imager 214 to capture images of the electrical equipment 12, so that the staff can determine the location of the fault arc.

[0029] In this embodiment, specifically: a handle 22 is fixedly connected to the front surface of the door 21, and the handle 22 facilitates opening and closing the door 21.

[0030] In this embodiment, specifically: a display screen 24 and operation buttons 25 are installed on the front surface of the control panel 23, which facilitates the operation of the control panel 23 by the staff.

[0031] In this embodiment, specifically: the ultraviolet light sensor 212, the ultrasonic sensor 213, and the infrared imager 214 are connected to the control panel 23. The ultraviolet light sensor 212 can capture the 185-260nm ultraviolet pulses generated by the fault arc. When the arc occurs, the number of ultraviolet photons increases sharply. The ultrasonic sensor 213 can receive the 20-100kHz high-frequency sound waves that accompany the arc discharge. It identifies abnormalities by sound pressure changes. If both exceed the threshold at the same time, it is determined to be a real arc, and an audible and visual alarm is immediately triggered and pushed remotely. At the same time, it can be optionally linked to trip the circuit breaker. If a single signal triggers, a self-test program is started, and the self-test is started and the log is recorded.

[0032] In this embodiment, specifically: the audible and visual alarm 26 and the drive motor 28 are electrically connected to the control panel 23.

[0033] In this embodiment, specifically: the rear surface of the door assembly 20 is provided with a main body assembly 10, which includes a housing 11 and electrical equipment 12;

[0034] Electrical equipment 12 is installed on the inner wall of the enclosure 11. The electrical equipment 12 includes common equipment in distribution boxes such as power modules, transformers, and circuit breakers.

[0035] In this embodiment, specifically: support legs 13 are symmetrically and fixedly connected to the bottom of the box 11, and the support legs 13 play a role in stabilizing support.

[0036] In this embodiment, specifically: the door 21 is hinged to the front surface of the box 11, and the door 21 is used to close the box 11.

[0037] In operation, this invention utilizes an ultraviolet light sensor 212 and an ultrasonic sensor 213 to detect ultraviolet light and ultrasonic waves emitted by a fault arc, thereby determining whether a fault arc exists within the distribution box and alerting staff to address it promptly. This prevents frequent occurrences of fault arcs at breakdown points that could lead to safety accidents. The ultraviolet light sensor 212 captures 185-260nm ultraviolet pulses generated by the fault arc, causing a sharp increase in ultraviolet photon count during arc occurrence. The ultrasonic sensor 213 receives 20-100kHz high-frequency sound waves accompanying arc discharge, identifying anomalies through sound pressure changes. If both exceed thresholds simultaneously, a genuine arc is identified, immediately triggering an audible and visual alarm 26 and sending a remote notification. Optionally, a circuit breaker may trip; a single signal trigger initiates a self-test program, recording data in a log. After a fault arc occurs, the drive motor 28 rotates the threaded rod 29, changing the position of the lifting seat 211. An infrared imager 214 captures an image of the electrical equipment 12, allowing staff to pinpoint the location of the fault arc and improving maintenance efficiency.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
