As rectifiers for metro traction substations complete set of converting sections series В-ТПЕД manufactured by
JSC “Pluton” and RESIBLOC® dry transformer manufactured by ABB company (Germany) or NOMEX transformer
produced domestically is applied.
Rectifiers are produced according to 12-pulse and 6-pulse “bridge” rectification circuits.

В-ТПЕД CONVERTER SECTIONS _

In development and production of В-ТПЕД converter sections (further CS) modern

technologies, materials and components of world-leading companies were used. CS are
constructed on power pill diodes 1600…2500А, 25
th
grade, produced by INTERNATIONAL
RECTIFIER company. CS cooling is natural air.

CS power part is made with application of maintenance-free contact joints
technology. Special German compensating devices, which fix clamps on contact joints,
irrespective of temperature and thermal diurnal and seasonal oscillation, are applied.
When assembling CS each bolted contact joint is crimped with torque wrench with certain
torque force in accordance with standards, and stated force remains during whole
operation life. Due to this fact, there is no need in periodical retorque, stripping of contact
joints during operation. Contact joint stabilization increases fire safety of switchgears and
substation as a whole.

Current division in parallel paths is forced and made with effective inductive
dividers providing current division between parallel paths no worse than 5%. Thus, during
operation of converters, in case of power diode replacement, there is no need to match
diodes by direct and reverse voltage drop.
Evenness of current division is preserved also during operation at natural
degradation of power diodes parameters. It is important criterion of reliability and absence
of necessity in periodic monitoring of equipment during operation.
There is power semiconductor devices protection against internal and external
switching overvoltage in rectifier. Diodes are protected against internal switching
overvoltage by RC circuits, against external - by RC circuits and varistors (overvoltage
protection panel).


CONTROL AND DIAGNOSIS MICROPROCESSOR SYSTEM _


В-ТПЕД CS are equipped with microprocessor control and diagnosis system.
Control and diagnosis microprocessor system is made on the basis of industrial
controller with PP41 visualization function and allows:
- to provide supervision of each diode condition in 4 criteria: “normal operation”,
“parameters degradation” (loss of class), “breakdown” and "fault”, and also to control diodes
temperature with information issue to visualization panel. Diagnosis according to these criteria
allows to increase sufficiently time of trouble-free operation over 80000 hours (9 – 10 years).
At the same time during operation information about parameters of each diode is taken in
dynamic;

- to provide control of some parameters of traction transformer.
Visualization panel represents module type industrial controller with LCD display and
feather-touch control.
Notation conventions of rectifier diodes condition, diagrams of reverse voltage
distribution between diodes and paths temperature are displayed in mnemonic form.
Signals displayed in main window:
• transformer overheating (I stage);
• transformer overheating (II stage);
• diagnosis failure;
• ground protection;
• connection absence;

• doors;
• CS overheating;
• diode breakdown;
• diode failure;
• diode parameters;

In case of diodes parameters alteration to the level corresponding to critical one for the given circuit (for applied
diodes), power diode can be replaced in no-current pause, without rectifier emergency break coming from diode

breakdown, which can happen in case of further degradation of unit parameters (class reduction).


Information about rectifier condition and its elements can be observed on visualization panel or on PC monitor by
means of specialized program.
In CS there is possibility of communication with upper level control system (central substation panel installed in
complete set of РУ-825 switchgear, medium voltage switchgears protection units, operator’s desk (telemechanics) both
by standard multi-wire system through terminal block and also by double-wire communication through RS-485 port for
the distance up to 1200m.



RESIBLOC® TRANSFORMERS _

As converter transformers JSC “Pluton” applies modern dry transformers manufactured by RESIBLOC®
technology with power of 1000kVA to 40000kVA with different combinations of voltage HV and LV (up to 45kV).
RESIBLOC® transformers are certified by State Standard of Russia and successfully operated in metros of Europe,
Kiev, Kharkov, Minsk, etc.
Transformer is connected with converter section by busbar bridge supplied in complete set.
Transformers have original design of primary and secondary windings made of copper wire and aluminum foil.
Windings are capsulated by fiber-glass string soaked in epoxy. Owing to original design of windings and epoxy
application technology RESIBLOC
® transformers are able to withstand maximum temperature fluctuations without
damage of epoxy surface and formation of microcracks. These are the only transformers able to operate at
temperatures up to -60
0
С.
Transformers operate under conditions of 100% humidity, water vapor
condensation and chemical pollution.
Transformers may be equipped with radial ventilators wit low noise level.

Cooling system allows to increase transformer rated capacity up to 40%.

Transformer windings resistance to mechanical loads is 650 – 750 N/mm
2
,
than its closest competitor - GEAFOL transformers. Described parameter is
especially important for converting transformers functioning in rapid starting current
mode.

All components of transformers were tested for toxicity absence. All materials
are non-inflammable and do not support burning. Transformers protection level is
IP00, IP21, IP23, IP54 acc. to GOST 14254-96.
RESIBLOC® transformer allows overload until the hottest heating point of
transformer reaches 155°С.
By customer’s request transformers are supplied with electronic unit of
temperature control. Unit is provided with two settings: for 140
0
С – alarm signal, for
155
0
С – load trip. There is a possibility of third setting – for 130
0
С – forced
ventilation activation.

Owing to described technological and design features RESIBLOC®
transformers perfectly fit in maintenance-free substation concept.
