GENERAL PRESENTATION
GENERAL DESCRIPTION INTRODUCTION TPR6 is an SF6 insulated ring main unit for the secondary distribution distribution network. TPR6 uses the latest developments in switchgear technology providing an extremely compact medium voltage switchgear solution and ensuring maximum personnel safety.
CONSTRUCTION CHARACTERISTICS TPR6 is a completely “sealed for life” system with a stainless steel tank containing all live parts and switching devices. The structure can withstand the electrodynamics stresses during the operation. The operating mechanism, movable mimic and voltage signaling lamps are positioned in the front panel. Switches are operated by means of spring-operated mechanisms. Movable mimic gives the position of the switch whereas the voltage signaling lamp indicates the voltages. Fuses and cable compartment compartment are easily accessible through the front door which is interlocked with the earth switch. If present, the low voltage auxiliary compartment compartment is situated above the ring main unit.
SAFETY CHARACTERISTICS The personnel safety is obtained by using mechanical interlocks: • When the switch disconnector is closed closed the earth earth switch switch can't can't be closed simultaneous simultaneously ly and the access to MV cables is prevented. • When the earth switch is closed there is a free access to MV cables but it is impossible to close the switch. • When the access door to MV cables and fuses is opened it is impossible to close the switch. Metal screens prevent access to electrical parts during maintenance operations. It is possible to block the switch in three positions with key locks.
INTERNAL ARC CLASSIFICATION The robust design of the metal enclosure prevents deformations and ensures protection against fault. TPR6 is designed to withstand an internal arc caused by a rated short-circuit short-circuit current up to 25kA for 1s preventing every danger to the operator.
THE TPR6 RANGE CONSISTS • • • • • •

VACUUM TECHNOLOGY Nowadays the interruption of current in vacuum is recognised as the dominant technology in medium voltage and as a consequence its use is continuously increasing. It is possible to have highly efcient vacuum circuit-breakers with electrical life which is longer than mechanical life, with total respect of environment; but in particular, vacuum circuit-breakers offer enhanced performances thanks to the reduction of arc energy, fast opening time, insulation recovery after overvoltage and reduction of mechanical energy needed for operating mechanism.

GENERAL DESCRIPTION INTRODUCTION TPR6 is an SF6 insulated ring main unit for the secondary distribution network. TPR6 uses the latest developments in switchgear technology by providing an extremely compact medium voltage switchgear solution. All this is obtained by ensuring maximum personnel safety.
CONSTRUCTION CHARACTERISTICS TPR6 is a completely “sealed for life” system with a stainless steel tank containing all live parts and switching devices. A hermetically sealed steel tank from the outside environment ensures a high level of reliability as well as personal safety. The structure can withstand the electrodynamics stresses during the operation. The operating mechanism, movable mimic and voltage signaling lamps are positioned in the front panel. Switches are operated by means of spring-operated mechanisms. Movable mimic gives the position of the switch whereas the voltage signaling lamp indicates the voltages. Fuses and cable compartment are easily accessible through the front door which is interlocked with the earth switch. Should the low voltage auxiliary compartment be present, it is situated above the ring main unit.
SAFETY CHARACTERISTICS The personnel safety is obtained by using mechanical interlocks. These mechanical locks operate as follows: When the switch disconnector is closed the earth switch can not be closed simultaneously and the access to MV cables (T, C and F modules) is prevented. When the earth switch is closed there is a free access to MV cables (T, C and F modules) but it is impossible to close the switch. When the access door to MV cables and fuses is opened it is impossible to close the switch (T, C and F modules). Metal screens prevent access to electrical parts during maintenance operations. It is possible to block the switch in three positions with key locks.
INTERNAL ARC WITHSTAND The robust design of the metal enclosure prevents deformations and ensures protection against fault. TPR6 is designed to withstand an internal arc caused by a rated short-circuit current for 1 second preventing any danger to the operator. A safety valve against accidental overpressure caused by an internal arc is located at the bottom of the metal enclosure. The gas is released to the bottom of the TPR6 without any danger to the operator. TPR6 has been type tested and it meets all the criteria of IAC class A FL, as dened by IEC 62271-200 standard, annex A. In case the rear pressure relief duct is used in the application the internal arc classication is AFLR (arc proof on four sides).
THE TPR6 RANGE CONSISTS
OF ALL OF THE NECESSARY MV FUNCTIONS ENABLING :
Connection and power supply on a open or closed ring network. Power supply and protection of transformers with circuit breaker or combined fuse- switches up to 200A. Power supply and protection of lines by a 630A circuit breaker Busbar coupling. MV metering. Earth switch for cable connection.

M AIN COMPONENT - SWITCH DISCONNECTOR SF6 GAS
Molecule of SF6
The insulation level inside the TPR6 modules has been obtained by means of sulphur hexauoride (SF6). This gas has a double function; it increases dielectric rigidity in comparison with air and aids electric arc extinction. The modules with the equipment insulated in SF6, have the following advantages: • General and electrical long life. • Maintenance-free. • Secure and stable operation. • Reduced sizes.
SWITCH DISCONNECTOR (S) This switchgear is made of a rotating part (movable-contact)which opens and closes the electric circuit.
POSITIONS : A) Closed B) Opened C) Earthed
THE SWITCH DISCONNECTOR

VACUUM CIRCUIT BREAKER TPR6 range includes 200A and 630A circuit breakers to protect transformers and line feeders. They can be provided with self-powered protection relays with ring core CTs on cables or protection relays with power supply. Circuit breakers guarantee making and breaking capacity under fault conditions such as short-circuits (phase-to-phase and phase-to earth), over currents and earth faults. In this way they provide operating safety, continuity of service and reduced maintenance costs.
