Parallel bus and electronics unit

The electronics units are of plug-in design and are mounted in equipment racks

with a standard size of 19 inches 6U (1U = 44.45 mm).

This rack can be divided into 21 standard partitions.

The data exchange via the parallel bus B448C is controlled and monitored by all available devices.

The protection system is based on a data bus with digital signal processing for most functions;

signal conditioning, analog and digital inputs, A/D conversion, processing and signal output.

The components of the system include

– Static plug-in units, which exchange data via a powerful parallel bus

– Interfaces to the process (main system, station equipment), isolated from the digital processing unit.

Device rack 216MB66/216MB68 and parallel bus B448C

The main features of the parallel bus B448C are

– Specification based on IEEE P 896 (Future Bus)

– Time multiplexing of address and data (16 bits)

– Asynchronous data transfer with handshaking

– Integrity check for each data exchange

– Up to 32 masters with the same status actively access the bus

– Internal 24 V auxiliary power supply common to all electronics units;

redundant 24 V power supplies are available.

Requirements

To ensure correct and safe operation of the relays, it is recommended that preventive

maintenance be carried out every five years on relays operating under specified conditions;

See table 4.1.-1 and section 5.2.4. Technical Data.

When used for real-time clock or logging data functions, the batteries should be replaced every five years.

Configuration

By appropriately configuring the output contact matrix, signals from the protection

level can be used as contact functions. The start signals can be used for

for blocking cooperating relays and for signaling.

The following figure shows the default configuration of the relay:

all trip signals are routed to trip the circuit breaker.

In the first example in Figure 4.2.-1. the residual current is measured by

the iron core balancing current transformer and the output contacts are

connected to enable the automatic reclosing function.

In the second example in Figure 4.2.-2. the residual current is measured through

the trimming connection of the phase current transformer and the output contacts are connected

to enable the trip lockout function with an external reset switch.

Applications

The REF610 is a multifunctional relay designed primarily for the protection

of incoming and outgoing lines in medium voltage distribution substations.

In industrial and utility applications, the relay can also be used as backup

protection for motors, transformers and generators.

The relay incorporates a number of protection features including three levels of overcurrent protection,

two levels of non-directional ground fault protection and thermal protection to

provide comprehensive overcurrent and ground fault protection.

An optional arc protection function can be used to detect arcing conditions in air-insulated metal-clad

switchgear,and an automatic reclosing function can be used to automatically clear overhead line faults.

These features further expand the range of applications for the relays.

The large number of digital input and output contacts allows a wide range of applications.

Overview

TIM foils or otherwise known as graphite sheet have been introduced in use in ACS800 mod

ules using EconoPACK+ IGBT as part of normal continuous improvements in the ACS800

product family. Benefits of using TIM foils in comparison to thermal grease are easier installa

tion and more durable heat transferring properties for longer periods of time. Durability par

ticularly improved in a cyclic application.

Where and how to use

TIM foils are used to transfer the heat generated in the IGBT’s to the heatsink. Full instruc

tions on how to install TIM foils is described in document delivered with TIM IGBT spare part

kits. It’s possible to use a mix of IGBT’s with thermal grease and TIM foils. In parallel con

nected R8i modules it’s also possible to use a mix of modules using TIM foils and thermal grease.
