A grounding wire 11 is provided inside the outer casing grounding port 8, and the grounding wire 11 passes through the wire buckle 12.

[0027] By providing structures such as the front cover plate 5, the anti-disengagement buckle 501, the upper fixing hook 503, and the lower fixing hook 504, the device is made more convenient to assemble and disassemble, and at the same time, the stability and safety of the device are enhanced.

[0028] The setting of the indicator light assembly 6 makes the working state of the device clear at a glance. Users can quickly judge information such as the operating state of the device, whether there is a fault, and whether it is live by observing the on and off states of different indicator lights.

[0029] The settings of the housing grounding port 8 and the fiber optic interface 9 make it more convenient for the device to be grounded and connected to other devices. The housing grounding port 8 can ensure the safe grounding of the device and prevent safety hazards such as electric leakage; the fiber optic interface 9 can achieve high-speed data transmission, improving the monitoring efficiency and data transmission stability of the device. At the same time, the split wire slot 10 provided inside the fiber optic interface 9 can effectively prevent wire chaos and improve the cleanliness of the device. By reasonably arranging the display screen 2, function buttons 3 and parameter configuration interface 4, users can easily perform parameter settings, data viewing and operation control. The display screen 2 can intuitively display the monitoring data, the function buttons 3 facilitate various operations for users, and the parameter configuration interface 4 enables users to perform parameter configuration according to actual needs, improving the flexibility and adaptability of the device.

[0030] During the design and use process of the partial discharge temperature monitoring device, safety is always given top priority. By setting a variety of safety indicator lights and grounding ports, it is ensured that the device can issue warnings in a timely manner in the live or faulty state, and grounding protection is used to prevent safety hazards such as electric leakage. This partial discharge temperature monitoring device has shown remarkable beneficial effects in terms of structural design, functional modules, interface settings, operation and use, and safety performance.

[0031] The working process of the partial discharge temperature monitoring device: When the device is powered on, it first performs an initialization operation, the display screen 2 lights up, and the initial interface of the device is displayed. Users can use the function buttons 3 to perform necessary parameter configurations on the device, such as setting the temperature threshold, discharge detection sensitivity, etc. After the configuration is completed, the parameters are transmitted to the control system inside the device through the parameter configuration interface 4. The device starts to work, and the internal partial discharge detection module starts to monitor the partial discharge situation of the monitored device in real time.

[0032] At the same time, the temperature sensor of the device starts to work, and the temperature change of the monitored device is monitored in real time. When the temperature exceeds the set threshold, the device will perform corresponding alarm processing. According to the monitoring results of partial discharge and temperature, the device will display the current working state through the display screen 2 and issue corresponding indications through the indicator light assembly 6. For example, when partial discharge or high temperature is detected, the corresponding warning indicator light will light up to remind the user to pay attention. The monitored partial discharge data and temperature data can be transmitted to an external data processing system through the fiber optic interface 9 for further analysis and processing. This helps users to more comprehensively understand the operating state of the monitored device and timely discover potential safety hazards.

[0033] Working principle: The working principle of the partial discharge temperature monitoring device is mainly based on partial discharge detection and temperature sensing technologies. The device captures the partial discharge signals of the monitored equipment through the built-in partial discharge detection module, using high-frequency coupling technology or ultrasonic detection technology. These signals usually appear as weak electrical signals or acoustic signals, which need to be amplified and filtered before being recognized and analyzed by the device.

[0034] The device measures the temperature of the monitored equipment in real time through temperature sensors such as thermistors and thermocouples. The temperature sensors convert the temperature changes into electrical signals, which are amplified and calibrated and then transmitted to the control system of the device for processing. After receiving the partial discharge signals and temperature signals, the control system of the device performs a series of signal processing and analysis operations. This includes steps such as signal filtering, amplification, and feature extraction to accurately judge the severity of the partial discharge and the change trend of the temperature. According to the processed results, the device determines whether an alarm signal needs to be issued. If an alarm is required, the corresponding indicator light will turn on, and the alarm information will be displayed on the display screen 2. At the same time, the monitoring data can be transmitted to an external system through the optical fiber interface 9 for further analysis and processing by the user.

[0035] The above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific implementation manners. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the present invention are covered by the scope of the claims of the present invention.
