The device has powerful integration and expansion capacities. It
not only satisfies the functional requirements of the current
distribution network automation, but also provides sufficient
expansion space for further improvement and upgrading. It boasts of
the following features:
Reliable and Stable Operation
The device inherits the rich R&D and onsite operation
experience of our company in relay protection devices, measuring
and control devices, communication devices and distribution network
automation. Many relevant aspects are taken into account and
various technical methods are adopted. The terrible operating
conditions for the device are fully taken into account in the
design. The device features excellent electromagnetic
compatibility, low power consumption and a wide range of operating
temperature. It is shockproof, moisture-proof, lightning-proof and
of great reliability and stability
Adequate and Practical Functions
It boasts of all the functions required for the present relay
protection and can carry out on/off combination according to the
practical requirements. It can fulfill the “four-remote” (remote
signaling, remote metering, remote control and remote regulating)
functions through the local serial ports and realize the remote
communication function by different optional communication modes.
Easy to Expand
The hardware and software platforms of the device are designed to
be equipped with the unified interface and expansion margin to
facilitate future expansion and technology upgrading, in order to
guarantee a longer service life of the device.
Easy to Maintenance
It can make self-diagnosis and self-recovery as it is equipped with
large-capacity non-volatile memory that can keep a detailed
historical record and will not cause data loss even under power
failure. Its interface is extremely user-friendly as it adopts LCD
display interface where information is displayed in multi-layer
menus in Chinese.
Date Storage
It is equipped with large-capacity non-volatile memory that will
not cause data loss even under power failure and can keep a
detailed historical record.
Atmospheric pressure: 66kPa～108kPa.
Operating environment: no explosive and flammable materials, no air
or conductive dust which will damage the insulation and cause metal
corrosion, no serious mold and no severe vibration sources, with
measures to defend against rain, snow, wind, sand, dust and static
electricity.
Remote metering area: It is at the right of the main interface,
indicating the remote metering data collected currently. The table
for remote metering symbols is as follows:
| Symbol | Representing remote signaling | Symbol | Representing remote signaling | Symbol | Representing remote signaling | Symbol | Representing remote signaling |
| Ia | Current of Phase A | Ua | Voltage of Phase A | I | Current | | |
| Ib | Current of Phase B | Ub | Voltage of Phase B | H | Frequency | | |
| Ic | Current of Phase C | Uc | Voltage of Phase C | P | Active | | |
