The last two letters of the order number indicate the rated frequency fn and the auxiliary voltage Uaux of the relay as follows:

AA equals fn = 50 Hz and Uaux = 80…265 V ac/dc

CA equals fn = 50 Hz and Uaux = 18…80 V dc

DA equals fn = 60 Hz and Uaux = 80…265 V ac/dc

FA equals fn = 60 Hz and Uaux = 18…80 V dc

ABB继电器SPAD346C/RS621002-AA先容

The stabilized differential relay SPAD 346 C is designed for protecting two-winding power transformers and generator-transformer. The main features include protection for winding short-circuits, interturn faults, earth faults and short circuits, as well as interwinding short-circuits and pole short circuits. In addition, the relay can be used for protection of three-winding power transformers, provided that 75% of the short circuit power to the power transformer is supplied from the same direction.

 

Scope

Integrated three-phase differential relay, three-phase overcurrent relay and multi-configurable earth-fault protection

 

Product benefits

Multi-functional protection functions

 

Product features

Integrated three-phase differential relay, three-phase overcurrent relay and multi-configurable earth-fault relay

Three-stage overcurrent module providing protection for power transformers and generators and two-stage backup earth-fault protection

Stabilized against unwanted operations at faults occurring outside the protected area and at transformer inrush

Second harmonic restraint for prevention of unwanted relay operations at transformer inrush

Fifth harmonic restraint for prevention of unwanted relay operations at transformer overexcitation

Wide CT ratio correction range - accurate correction through digital setting

Four heavy-duty output relays for circuit breaker tripping and five output relays for signalling

Five programmable external control inputs

Integrated circuit breaker failure protection with adjustable operate time

Differential relay and earth-fault relay modules with integrated disturbance recorder functions for analog and digital signals

Sensitive phase current and phase angle displays facilitate checking of energizing circuit connections and vector group matchings

High immunity to electrical and electromagnetic interference allows the relay to be used in severe environments

High availability and system reliability due to continuous supervision of hardware and software

 

SPAD 346 C 稳压差动继电器专为保护两绕组电力变压器和发电机变压器而设计。主要功能包括对绕组短路、匝间故障、接地故障和短路以及绕组间短路和极短路的保护。此外,继电器可用于三绕组电力变压器的保护,前提是电力变压器75%的短路功率由同一方向提供。
