PRS-761 smart terminal

Product Description

PRS-761 smart terminalis developed based on the IEC61850 standard for digital substations, which is applicable to transformers and reactors. The device has a fully open digital interface, which can be seamlessly connected with primary intelligent equipment (primary intelligent switch), and is also compatible with conventional primary equipment. The device provides interfaces according to the IEC61850 protocol, which has no restriction on network type. It can achieve flexible networking, and can be applied to various networking methods at the process level.

Scope of Application

It is applicable to intelligent substation transformersof various voltage levels.

Technical Features/Advantages

It has the functions of non-electrical quantity tripping, alarm and originating.

It has the functions of transformer position collection and remote regulating.

It can collect and upload the positions of knife switch and grounding knife switch, and the switch signal through GOOSE communication.

It can receive the GOOSE command for knife switch and grounding knife switch control from measurement and control, and output the corresponding action contact.

It supports the substation communication standard IEC61850, and the number of SV/GOOSE message receiving ports can be configured.

The device adopts 64-bit high-performance CPU, internal high-speed bus and intelligent I/O, and both software and hardware have modularized design, which can provide flexible configuration and plug-and-play.

The device adopts the 4U entire layer, reinforced case, multi-layer shielding, strict separation of strong and weak currents and other anti-vibration and anti-interference designs, which has high anti-interference performance, and is suitable for installation in harsh environments.
