This invention relates to a temperature control system for FTU battery packs, belonging to the field of power distribution automation technology. It includes an FTU device, a standard 5-pin backup power interface, a DC24V power supply, a battery pack, a temperature sensor, a heating element, and a temperature controller. The battery pack is connected to the FTU via pins 4 and 5. The temperature sensor is connected to the temperature controller via pin 1. The positive and negative terminals of the heating element are connected to the temperature controller via pins 2 and 3. The temperature controller is connected to the DC24V power supply and compares the temperature signal collected by the temperature sensor with a temperature threshold to control the start and stop of the heating element, achieving closed-loop temperature control of the battery pack. This invention achieves a "zero-destructive" upgrade of existing equipment, eliminating the need for opening holes or external wiring in the FTU protective enclosure. It retains the original sealing and protection rating (IP rating) of the equipment at the factory, preventing changes in the operating environment such as water ingress, condensation, and dust that might be introduced during modification, thus ensuring the long-term reliability of outdoor electrical equipment.

This invention discloses a continuous ultrasonic amplification standing wave field-ozone micro-nano bubble synergistic inactivation device for mariculture, comprising a seawater pretreatment unit, an ozone micro-nano bubble generating unit, an ultrasonic amplification standing wave field-ozone micro-nano bubble synergistic inactivation reaction unit, a multi-parameter effluent detection unit, and a closed-loop control unit connected in sequence. The reaction chamber adopts a three-layer coaxial nested configuration of 316L stainless steel. The inner tube wall has a regular polygonal prism structure, while the outer tube wall has a multi-segment continuously circulating "gradually expanding-constant diameter-gradually contracting" irregular tube structure. High- and low-frequency multi-array ultrasonic transducers are correspondingly arranged on the inner and outer wall surfaces to synergistically construct a blind-zone-free gradient amplification standing wave field. This invention achieves efficient and continuous inactivation of pathogenic microorganisms in mariculture water by targeting and enriching pathogenic microorganisms at the acoustic pressure nodes of the standing wave field, concentrating the excitation of multi-frequency resonant cavitation effects at the acoustic pressure antinodes, and coupling ozone micro-nano bubbles to reduce the cavitation threshold and leverage their high oxidizing properties.
