Henan Bangxin solid state decoupler (BX-SSD/EX-100) is often used for decoupling of pipeline potential gradient pads (grounding pads), and overvoltage protection for AC faults, lightning and switching transients of equipment (eg: Insulated joints, insulated flanges). In order to be safely used for decoupling between different metals, these metals may be AC ​​coupled in some cases. In the cathodic protection system, the AC grounding and DC isolation of the electrical equipment reduces the AC induced voltage.
As a DC isolation and AC coupling device, the BX-SSD/EX-100 is used to prevent the cathodic protection current from reaching a predetermined threshold voltage while also conducting induced AC. When the voltage force diagram exceeds the threshold voltage, the SSD immediately switches to the short-circuit mode to provide overvoltage protection. When the overvoltage has passed, it automatically switches back to DC isolation mode. This mode of operation can be performed innumerable times, usually due to AC fault current or lightning current.
KNB1-63 Mini Circuit breakers, also named as the air switch which have a short for arc extinguishing device. It is a switch role, and also is a automatic protection of low-voltage electrical distribution. Its role is equivalent to the combination of switch. Fuse. Thermal Relay and other electrical components. It mainly used for short circuit and overload protection. Generally, According to the poles, mini Circuit breaker can be divided into 1P , 1P+N , 2P, 3P and 4P.
