031-8555-135 is a type of high-voltage capacitive arc protection (CAP) device designed for outdoor power distribution switching in hazardous environments. It is mainly used for protectively isolating high-power arc flashes and preventing the occurrence of electric shock incidents.The working principle of 031-8555-135 is based on a combination of short-circuit current limiting (SCLC) and voltage decay methods. In SCLC, the current is limited to a pre-defined threshold to prevent it from exceeding the capability of the switchgear. In voltage decay, the voltage is controlled to decrease progressively, until it reaches a safe level for personnel to approach and operate the switchgear.This high-voltage CAP device also provides additional safety measures for indoor-type switchgear. It can detect and limit the energy released from arc faults by limiting the current flow through the device and then reducing the power available for the arcing current. This helps to prevent any further arcing from occurring, significantly reducing the possibility of damage or personal injury.Another application field of 031-8555-135 is air-insulated switchgear, where it can detect the presence of arcs and limit the current flow through the device to prevent harm to personnel and equipment. With its ability to detect the presence of arcs in microseconds and limit the current within milliseconds, it provides a high level of safety in hazardous environments.The 031-8555-135 is also suitable for controlling the current through medium-voltage cables or medium-voltage switchgear, where it can quickly detect high-frequency faults and limit the current to the predetermined maximum. By doing so, it helps to protect personnel and equipment from potentially dangerous situations.In addition, 031-8555-135 can be used to control the current through transformers, making them safer to operate and less susceptible to any faults.Finally, 031-8555-135 can also be used in medium- and high-voltage busbars, where it can help to reduce the current levels that can be caused by an arc fault. This helps to reduce the risk of equipment damage or personnel injury.From the above, it is easy to see that 031-8555-135 is a versatile device with an extensive range of applications in hazardous environments. With its combination of current limiting and voltage decay methods, it provides a high level of safety and protection for personnel, equipment and outdoor power distribution systems.
