BP600
series microcomputer programmable protection and supervision device is a
digital relay protective device used for the protection, control, measurement
and supervision of 110KV and below power grid, able to operate under different
connection systems (such as single busbar, dual busbar, multiple busbars) and
different power grids (neutral point unearthed system, or the system earthed through
arc suppressing coil, or small resistance), to provide the protection and
supervision function for feeder, capacitor bank, motor, backup protection of
transformer, auto-switching of backup source and etc; also it can be used to protect
the middle-size three-phase asynchronous motor, or control and protect the
shunt capacitor bank.
Different ports: 8CT,4PT,3AI,16/32DI,11/16DO,
to realize different connection modes.
Multiple
communication passages: lRS485,1CAN,1RS232 commissioning, 2 Ethernet and one pair of optical fiber (optional)
Various
connection modes: suitable for different PT, provide the real time wave and
angle of AC parameters, to help the verification of connected polarity.
Powerful
graphic programming: complete programmable resources provided for graphic programming,
easy operation, widely applications, and protections can be designed according
to user request.
High
reliable design: all components are of industrial level, full electric
isolation is executed, completely in consideration of EMC, self-detected
function and etc, all of these ensure the device can operate durably and
reliably.
Full event
analysis and record: able to record the waves of 8 events and latest 100 pieces
of SOE events.
High
accurate measurement: The accuracy to measure voltage, current and power factor
reach up to 0.2 class, the accuracy of measuring the power and KWh up to 0.5
class.
Precise
time calibration: time calibrated through the panel by hand or through
communication, or by IRIG-B code.
The
panel has full functions of showing and adjustment: large LCD can display the
self-defined wiring diagram, running menu/interface, local ON/OFF operating is
available.
