Abstract
Description
Technical Field
[0001] This utility model relates to the field of partial discharge detection technology, and more specifically to the field of a self-powered built-in partial discharge acquisition device. Background Technology
[0002] With the rapid growth in the application of GIS equipment and the increase in operating time, GIS equipment failures occur frequently. Sensors for partial discharge detection are mainly divided into external sensors and internal sensors. External sensors are susceptible to interference from external electromagnetic signals, resulting in lower monitoring sensitivity and poor anti-interference capabilities, making them unsuitable for long-term online detection.
[0003] Therefore, built-in sensors are currently the preferred choice for partial discharge monitoring. However, built-in sensors usually require battery power, and the depletion of power will severely affect the operation of partial discharge monitoring. Charging technology has not yet been widely used in built-in UHF sensors. Utility Model Content

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0006] This utility model provides a self-powered built-in partial discharge acquisition device, including a sensor module, an energy harvesting module, a transmission module, and a data control module. The energy harvesting module is used to power and drive the sensor module, transmission module, and data control module respectively. The sensor module acquires partial discharge signals and transmits them to the data control module via the transmission module.
[0007] In one embodiment, the data control module includes a data acquisition unit, a data processing unit, and a data storage unit that are electrically connected in sequence; the data acquisition unit is connected to the sensor module.
[0008] In one embodiment, the sensor module includes a built-in UHF sensor and a temperature sensor. The built-in UHF sensor collects partial discharge signals, and the temperature sensor acquires the ambient temperature of the device. The data control module receives the partial discharge signals and the device temperature data, determines the type of partial discharge, and issues an alarm when the temperature reaches a critical value.
[0009] In one implementation, the transmission module includes a Bluetooth unit and a Wi-Fi unit. The built-in UHF sensor transmits partial discharge signals in the field via Bluetooth or Wi-Fi connection, reducing wired connections.
[0010] In one implementation, the data acquisition unit processes the partial discharge signal by filtering, noise reduction, and amplification and then outputs it to the data processing unit.
[0011] In one embodiment, the data processing unit receives a partial discharge signal, performs analog-to-digital conversion, and outputs it to the data storage unit.
[0012] In one embodiment, the data storage unit receives and stores the partial discharge signal.
[0013] In one embodiment, the power harvesting module includes a lithium battery, a coupling capacitor, a temperature compensation unit, and a protection unit. The lithium battery is charged by voltage division through the coupling capacitor of the built-in ultra-high frequency sensor, thereby driving the data acquisition, data processing and storage, and transmission modules. The temperature compensation unit enables the sensor to be used in environments with large temperature variations, enhancing environmental adaptability. The protection unit prevents excessive current from damaging the internal control chip.
[0014] In one embodiment, a display module is also included for displaying partial discharge signal spectra and device temperature, for viewing real-time PRPS spectra and temperature conditions.
[0015] The beneficial effects of this utility model are as follows:
[0016] This invention optimizes the energy harvesting module, couples discharge electromagnetic wave signals within the GIS, and enables the detection, diagnosis, and location of partial discharge signals, as well as the monitoring of equipment temperature, ensuring the security and reliability of data transmission. It also optimizes energy harvesting and storage technology, reducing dependence on external power sources, adapting to various environmental conditions, and improving the system's reliability and stability.
