ABB繼電器SPAD346系列介紹
ABB繼電器SPAD346C/RS621002-AA介紹
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 穩壓差動繼電器專為保護兩繞組電力變壓器和發電機變壓器而設計。主要功能包括對繞組短路、匝間故障、接地故障和短路以及繞組間短路和極短路的保護。此外，繼電器可用于三繞組電力變壓器的保護，前提是電力變壓器75%的短路功率由同一方向提供。
