3. Challenges The protection on the main feeder is generally overcurrent and short circuit protection device. Its disadvantage is that it is unable to provide segmented protection for users and cut off the fault area in real time when short circuit and other faults are detected, resulting in power failure of the whole feeder and affecting the normal life of residents using power equipment. In addition, the inability to provide precise protection for users may also lead to increased power loss and shortened equipment life. Revenue loss or fine penalty due to power outage High O&M cost due to frequent fuse blow Few protection functions can not solve the fault The equipment is old and the operation interface is too complicated

4. Hexing Solutions Three-phase recloser HXD811 series (for A/B/C/D/E); Three-phase recloser : mainly used to protect the main line and some branch lines of the overhead line of the distribution network, with complex functions and wide protection range; HXD811-15.5 T hree-phase Recloser 15.5kV, 630A ; Passed the ASTA international certification ; Distribution network feeder main line protection ; Cost-effective recloser products ; Relay of Hexing brand ; More flexible configuration schemes (switches, controllers)

It has the characteristics of small size, stable performance and excellent anti-condensation performance. Each pole includes a vacuum interrupter for fast arc extinguishing, fault isolation and reliable reclosing sequencing. Line faults are accurately detected and provide fast and reliable isolation. Automatic circuit recloser

6. Hexing Solutions Components in control unit HXD811 control unit is designed for 15kV, 27kV and 38kV recloser manufactured by Hexing. It is used for the signal collection and fault protection in the distribution line. When there is a short circuit or earth fault, it can detect and recognize the fault type and then conduct the protection action based on the protection principle set by users, such as warning, trip and reclosing, or report to the main station and the main station will give it operation command according to different protection principles.
