REX521GHHPSH51G 饋線保護繼電器

REX521GHHPSH51G是ABB公司生產(chǎn)的一款饋線保護繼電器。這款繼電器主要用于饋電線路的保護，其關鍵作用在于監(jiān)測饋電線路的運行狀態(tài)，并在檢測到異常情況或故障時及時采取措施，以防止故障擴大并對整個電力系統(tǒng)造成損害。

具體來說，REX521GHHPSH51G饋線保護繼電器具備以下功能：

1. 過流保護：當饋電線路上出現(xiàn)超過額定電流的電流時，該繼電器會及時切斷電路，防止過流引起的設備損壞或火災等危險情況。
2. 短路保護：它能夠檢測饋電線路上的短路故障，并在檢測到短路電流時迅速切斷電路，以防止短路引起的嚴重損害。
3. 接地故障保護：對于中性點接地的電力系統(tǒng)，該繼電器還能夠檢測接地故障，并采取適當?shù)谋Ｗo措施，確保電力系統(tǒng)的安全運行。

此外，REX521GHHPSH51G還具有高可靠性，采用優(yōu)質的元器件和嚴格的測試工藝，確保繼電器穩(wěn)定運行。其安裝簡便，維護方便，適用于各種工業(yè)和民用領域的電力系統(tǒng)，如工廠、商業(yè)建筑和住宅等。

作為一款ABB公司的產(chǎn)品，REX521GHHPSH51G饋線保護繼電器繼承了ABB在電力和自動化技術領域的卓越品質和技術支持。用戶可以獲得可靠的產(chǎn)品性能、完善的技術支持以及及時的售后服務，確保電力系統(tǒng)的穩(wěn)定運行和安全性。

REX521GHHPSH51G 饋線保護繼電器

The REX521GHHPSH51G is a feeder protection relay manufactured by ABB. This relay is mainly used for the protection of the feed line, and its key role is to monitor the operating status of the feed line and take timely measures when abnormal conditions or faults are detected to prevent the fault from expanding and causing damage to the entire power system.

Specifically, the REX521GHHPSH51G feeder protection relay provides the following functions:

Overcurrent protection: When the current exceeds the rated current on the feed line, the relay will cut off the circuit in time to prevent equipment damage or fire caused by overcurrent.

Short-circuit protection: It can detect the short-circuit fault on the feed line and quickly cut off the circuit when the short-circuit current is detected to prevent serious damage caused by short circuit.

Ground fault protection: For power systems grounded at neutral points, the relay is also capable of detecting ground faults and taking appropriate protective measures to ensure the safe operation of the power system.

In addition, the REX521GHHPSH51G is highly reliable, with high-quality components and a rigorous test process to ensure stable operation of the relay. It is easy to install and maintain, and is suitable for a variety of industrial and civil power systems, such as factories, commercial buildings and residential buildings.

As an ABB product, the REX521GHHPSH51G feeder protection Relay inherits ABB’s outstanding quality and technical support in power and automation technology. Users can obtain reliable product performance, perfect technical support and timely after-sales service to ensure the stable operation and safety of the power system.
