Product category: Product Center Special Transformer Series Product Description: three cavity explosion proof and reliable   Explosion proof and reliable; Higher precision; Stable performance. Technical innovation: 1, three cavity integration, explosion-proof and reliable; 2. 1A step setting, higher precision; 3. Fault memory, password locking; 4. PLC protection, stable performance.   Features: 1. The core control system is composed of imported industrial programmable controller (PLC) and human machine screen (got). Stable performance, precise protection and simple maintenance. 2. The operation status, power parameters and faults are displayed on the human machine screen (got), and the interface is all Chinese LCD; The parameters are set in the man-machine screen, and the parameter setting has the password locking function. 3. The current can be adjusted continuously and the step value is la. 4. It has independent circuit breaker cavity, disconnector cavity and wiring cavity; It can realize live maintenance, safe and reliable operation and maintenance. 5. It has the characteristics of small volume, reasonable structure and intuitive operation, and has electric and manual energy storage double closing mechanism. 6. It has complete protection functions, such as overload, short circuit, overvoltage, undervoltage, leakage, leakage locking, phase loss, overtemperature, wind power and gas locking, emergency stop of superior power supply, etc., and can protect the fault fed back by the low voltage side of the transformer. 7. PLC intelligent protection has the functions of system self check, fault diagnosis, patrol inspection and memory, real-time detection and digital display of operation status and fault indication, which is convenient for system use, maintenance, fault judgment and processing. 8. Modular design, equipped with standard RS232 / 485 communication interface, with powerful remote communication and control functions. 9. All faults are broken by the signal line driving the vacuum circuit breaker at the high voltage side, thus reducing the breaking current, and overcoming the dead time problem of the transformer low voltage winding to the low voltage switch circuit leakage can not be broken. 10. The protection box is divided into four circuit outgoing lines on both sides, which can meet the connection of multiple loads.
