Overview
Essential details：REF545KM133BAAA feeder protects the terminal
REF 541, REF 543 and REF 545 series feeder end
The end is designed for protection, control, measurement and use in medium voltage power grids Surveillance. They are suitable for different main wiring modes, such as single female Wire, double bus and double switch wiring. Protection is also supported Different types of power grids, such as neutral ungrounded systems, resonance Grounding systems and small resistance grounding systems. The feeder terminal can still respond
For three phase asynchronous motors, based on frequency and voltage protection Protection, thermal overload protection, check the same period/check no voltage function and no Protection and control of power compensation shunt capacitor banks. Besides having Protect, measure, control and condition monitoring functions outside the feeder line
The terminal also provides complete PLC logic programmable function, PLC
The function enables the automation required by the substation integrated automation system Function and sequential logic control functions are integrated into one device.
Feeder terminals can also use IEC 60870-5-103 protocols,
DNP 3.0 protocol, IEC 61850, Profibus-DPV1,
Modbus protocol, SPA protocol or LON network implementation
Layer device communication. And, with the support of the LON network
Point-to-point communication function, feeder terminals can communicate with each other
Exchanging information reduces hard wiring between feeder terminals.

REF545KM133BAAAÂ feeder protects the terminal
The control function is used to display the status information of the primary device, for example For example, circuit breakers and isolating switches are used to implement primary devices The control of. In addition, control functions are provided for control logic The on/off function, data monitoring of various object control and so on.
All control functions and control logic can use relays
Configuration software tuning, device large LCD screen MIMIC configuration drawing Surfaces can also be edited with the Relay Configuration tool software. One-off setting
The standby status is displayed on the device LCD screen and implemented in place Control. Switch the display of different states of the device on the MIMIC screen
The indication mode, such as on/off/indeterminate, can be arbitrary Designed.
Fault location
The fault location function applies to the radial power distribution system. In various kinds of The type of distribution network that determines the short circuit point in the small resistance/small current
Determine the grounding position in the anti-grounding system, which can help the power grid in the fault The power supply can be quickly restored after the fault, which greatly improves the reliability of the grid.
Status monitoring function REF 54_ Feeder protection terminal has status monitoring function,
This function includes monitoring and switching of current and voltage input circuits Circuit breaker operation times counter, circuit breaker accumulated electrical wear Calculation, maintenance planning, trip loop monitoring and circuit breaker travel Time monitoring, etc.
