ALL THE ADVANTAGES OF EPOXY RESIN

For sets, transformers and connection interfaces :

single-phase from 1 kVA to 50 kVA or

three-phase from 5 kVA to 160 kVA

The use of epoxy resin guarantees that the transformers have the following characteristics :

Corrosion resistant, remain unaltered over time.

Watertight and immersible.

Insulated.

Can be buried into purposedely-deisgned pits.

MODULOBLOC MAIN CHARACTERISTICS

Watertight and immersible sets

Conform to NFC 52 410 standards and CEI 76

Dielectric : Dry, epoxy, up to 6 kVA

Oil from 8 to 160 kVA

Primary insulation voltage : 7.2 kV

Secondary insulation voltage : 1.1 kV

Reduced losses

Protection degree : IP 68 - IK 10

Working temperature : -15 °C +40°C

Impulse withstand : 45 kV wave shape 1 / 50

Withstand industrial frequency : 5.5 kV : 22 kV - 50 Hz - 1 minute

: 3.2 kV : 16 kV - 50Hz - 1 minute

Especially designed to support the no load lamp stress.

Studied to allow network continuity in case of a transformer default.

MV PLUG-INS ON THE SEPARATED CONNECTION INTERFACE :

The MV plug-in terminal systems of the connection interface guarantees total operational flexibility :

Easy to plug in and unplug.

Optimum reliability : the watertight connections rarely come in contact with water.

Regardless of type of cable used, a specially designed plug-in terminal answers all your requirements.

Absence of voltage test, earthing and short circuiting checking compartments, in conformity with

recommended NFC 17-200 standards, accessible directly on the top of the interface.

IDR Tri with a network input and

output on the twisted three-pole cable

and a transformer supply derivation.

IDR Bi with a network input and output on the two

pole cable, an output network on the twisted single

pole cables and a transformer supply derivation.

The transformers low voltage output is carried out with a 1.5 meter H 07 RNF cable. A LV plug-in terminal for the

transformers with a power rating superior to 8 kVA can be provided.

DOUBLE « AUTO » PROTECTED TRANSFORMERS :

Protection devices directly incorporated in the transformer guarantee :

MV protection with easily-accessible HRC fuses

Thermal protection using a thermal probe on a 1.5 meter long cable

Optional : Low voltage protection using thermal-magnetic circuit breaker or fuses installed in a separate cabinet

allowing protection against short circuiting with the possibility of several feeders. Starting from 8 kVA this

protection can be integrated directly on the transformer.

ADVANTAGES OF MODULOBLOCS SERIES

A complete range of equipment to carry out absence of voltage tests available

on request, conforming to recommended NFC 17-200 standards.

Connection accessories routinely delivered with each transformer.

Voltage adjustment tap changers of +-5% provided to transformers from

16kVA and to the three-phase transformers of all power ratings.

Selection of phases carried out directly on IDR connection interface enables,

using the single-phase transformer installed on three-phase networks, the

charge on the three-phases of the network to be balanced.

On request, AUGIER technicians carry out on site

technical assistance, in France start up of MV installation

and guarantees technical training leading to full

understanding of the technical features of the product and

how it works.

The IDR connection interfaces are also used as deviation boxes. MV networks epoxy resin accessories are also

available. They enable cable isolation to be carried out, among other things.

MODULO BI RANGE

Electrical modular equipment comprising the single-phase 3200 V network

The range of MODULOBLOC products consists of TEE or TED-E transformers, IDR connection interfaces and

annex equipment.

EXAMPLES :

All above sets have a checking compartment allowing absence of voltage text to be carried out as well as earthing

and short circuiting (MALT / CC), conforming to NF-C 17 200 and UTE 18510 standards and requirements.

DESIGN CHARACTERISTICS

-Functional separation in three parts guarantees optimal reliability and easy access to maintenance points:

*The transformation and MV fuse protection part, installed at bottom of the pit, are immersible. There is no

connection point and therefore it needs no maintenance.

*The connection part installed in the upper part provides easy access to all circuit points, the phases or neu

tral position is clearly visible.

*Low voltage protection is optional.

- Application of regulations in force guarantee safety of maintenance workers:

*A specially-provided compartment is directly accessible for this, situated on top

*The absence of voltage test is carried out directly on the network, without interface.

*Earthing and short circuiting is carried out before any handling of the terminals.

- Easy installation:

*Easy- to- assemble and operate connections : only network ends need to be built.

*Connection to the network is carried out by one- pole plugs.

*Equipment standardisation: connection box has only one model, fewer transformers and low voltage cubicles.

CONNECTION INTERFACE IDR TRI

INTERFACE IDR TRI

Epoxy resin monobloc terminal, pluggable, waterproof IP68, three -pole, lockable, to be fixed to the pits walls, with

the following characteristics:

Insulation voltage: 7.2 kV

Closing power rating in operation 5.5 kV three phase: 1000 kVA

This terminal consists of four, three -pole pluggable inputs allowing the following functions:

Input line.

Output or derivation line.

Derivation towards a TEE or TED-E transformer

Absence of voltage test as well as carrying out earthing and short circuiting.

Conditions of use: For easy maintenance and even with the IDR having protection degree IP68, we recommend its

use in an environment compatible with the AD7 class «can be totally or partially immersed in water temporarily».

INTERFACE IDR EQUIPMENT:

Stainless steel wall fixation support Three -pole plug

FTR assembly kit for use with all types of

three- pole belt or twisted cable from 6 to 35 mm².

Male three-pole plug

Manipulated with a safety rod equipped with a CMB

key for absence of voltage test, and carrying out

earthing.

ANNEX EQUIPEMENTS

SPECIFIC MAINTENANCE TOOLS:

The CMB operation key for three- pole plugs allows

extraction of male three- pole plugs and placing of

earthing plate, with the help of a safety manipulating

rod.

The earthing and short circuiting plate, PMC,

manipulated with a safety rod, must be used only

after extraction of the male three- pole plug.

The BTM male three- pole plug can be used

to insulate any one of the four three- pole IDR

inputs.

The BTF female three -pole plug can be used to

insulate either a three- pole plug or no more than

three single- pole plugs.

EQUIPMENT FOR EARTHING, IF NEEDED, PLUGGABLE PARTS:

The earthing and short circuiting plate, PMC, can

earth any one of the four three- pole IDR inputs. The earthing and short circuiting plug allows the

earthing of either three -pole plugs or no more than

three single -pole plugs.

MAINTENANCE ACCESSORIES

Accessories described on page 11.

LOCKING SYSTEM

PRINCIPLE

Using an interlocking system access to the transformers and connection interface are dependant on the earthing and

short circuiting of the cabling supplied at origin. This is carried out using an interlocking key together with a Ronis

or Profalux key.

MANHOLE LOCK

The TED key can activate a safety lock

to release the grid located inside the

inspection manhole between access

cover and transformer.

Only specific pieces, corresponding to

figures 5, 7 and 8, are listed in Augier

rates.

LOCKING TRANSFORMER TERMINALS AND CONNECTION INTERFACES If the manhole locking system cannot be used, a terminal locking system of fuse terminals can be installed directly

on the transformer and MV terminals on the connection interface. The operating principle is the same as for the

manhole lock, using a locknut.
