Realize the optimal control and safe operation of the switching station

REC670 – Maximum flexibility and performance

REC670 Intelligent microcomputer protection device for various types of switchgear (AIS/GIS) And a variety of wiring switchgear provides user-defined or pre-configured control

Plan. The custom RET670 1MRK004816-AC gives you complete freedom according to your needs Function selection. Because the REC670 basic features have been selected and configured in the deviceTherefore, the pre-configured REC670 can be put into use with simple operations. Such as

If desired, you can also easily add optional features to the REC670 device to full capacity Meet the special configuration needs of your switch station.

RET670 1MRK004816-AC enables users to implement on-load voltage regulation through substation automation systems

Motion control. Users can simultaneously install advanced transformer tapping in one REC670

Head automatic regulation (AVC) function, so no phase is configured for in-station transformer protection

When the automatic voltage control function is required, it is not necessary to install special voltage control equipment.

The RET670 1MRK004816-AC’s outstanding on-off capacity enables multiple intervals to be achieved with only one device

Control. For example, a single REC670 device has the ability to connect a string of 1 1/2 wiring modes at intervals

All equipment in the test and control function, and including all circuit breaker failure protection. Due to the

Therefore, the REC670 can be used at any voltage level that includes different protection and control systems

For any substation, simplify system design and effectively reduce costs.

A single REC670 can be used to control a whole string of all switchgear in 1 ½ connection mode. REC650 is applied in a single bus and single circuit breaker connection mode

The Relion® 670 Series microcomputer protection devices also support synchronous sampling value communication based on the IEC61850-9-2 LE standard process bus instead of the traditional hard wiring between the process layer and the secondary system. This capability enables the substation to achieve completely new designs, for example, using sensor technology to solve related problems such as CT saturation and electromagnetic interference. In addition, the use of fiber optics instead of traditional hard-wired substations is more efficient for renovation and maintenance.

The 670 Series microcomputer protection device supports both conventional hardwired and IEC61850-9-2 LE standard optical fiber communication on the same device. This enables the transformation of optical fiber communication from traditional hardwiring of analog quantities to synchronous sampling measurements to be completed in a step-by-step manner.
