WHB-52A Integrated protection device

Application scenarios

WGB-50A Microcomputer-based integrated protection device is suitable for all kinds of power distribution and power consumption places with 10kV voltage class and below.

The device adopts a variety of adaptive technologies and all-in-one design concepts to facilitate project selection and field application.

The device can be flexibly configured according to the usage occasion, and the protection object can select line, transformer, capacitor and motor.

Line protection is mainly applies to protect line and feeder line protection with 10kV voltage class and below.

Transformer protection is mainly applies to protect transformer, substation service transformer and grounding transformer used in small earth current system or a small resistance earth system with 35kV voltage

class and below.

Capacitor protection is mainly applies to protect parallel capacitors installed in power distribution and power consumption sites with 10kV voltage class and below.

Motor protection is mainly applies to protect small and medium-sized asynchronous motors below 2000kW with 10kV voltage class and below.
