4、 Typical waterproof application scenarios (system level)
Water treatment plant pump station: The I/O station is installed in an IP66 outdoor box to monitor liquid level and valve status
Food and beverage production line: frequent flushing area, using stainless steel IP67 junction box
Ship/offshore platform: high salt spray, high humidity environment, combined with anti-corrosion sealing box
Tunnel/subway drainage system: damp and occasionally splashed with water, using IP65 protection
Key features and functions:
Overcurrent protection: Detects excessive current flowing through the transformer and initiates appropriate protective actions to prevent damage.
Differential protection: Compares the currents flowing into and out of the transformer to detect internal faults within the transformer windings.
Bucking protection: Protects against short circuits between the high-voltage and low-voltage windings of the transformer.
Overheating protection: Monitors the temperature of the transformer and initiates protective actions if it exceeds safe limits.
Gas detection: Detects the presence of gases produced by faults within the transformer, such as hydrogen or carbon monoxide, and initiates appropriate actions.
Communication: Communicates with other system components, such as the substation control system and protection relays, to coordinate protection and control functions.
Applications:
Substations: Used in various types of substations, including power generation, transmission, and distribution substations.
Industrial facilities: Employed in industrial facilities that require reliable and efficient power distribution, such as manufacturing plants, data centers, and hospitals.
Grid systems: Utilized in electrical grid systems to protect power transformers and ensure system stability.
