Products Description
Structure and Measurement Principle
2、 Core intelligent performance characteristics
1. Embedded processing capability
Built in microprocessor, capable of executing:
Linearization of signals (such as thermocouples, RTD temperature compensation)
Conversion of Engineering Quantity Units (mA → ° C/bar/%, etc.)
High and low limit alarms (H/L, HH/LL) and rate of change detection
Digital filtering (suppressing on-site interference)
2. High reliability design
Support hot swap: modules can be replaced during system operation without shutting down
Complete diagnostic function:
Channel level fault diagnosis (open circuit, short circuit, over range)
Module self-test (CPU, memory, communication status)
LED indicator lights display real-time running/fault status
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.
