TFLW34F – 12, outdoor intelligent vacuum load switch complete set, is an intelligent complete set based on the outdoor vacuum load switch. The device is mainly composed of the ontology of a vacuum load switch of TFLW34F – 12 and a TF intelligent demarcation switch controller. It is installed at the point of common coupling of distribution power line users’ service wire at the 3 – 12 KV voltages, and it can also be installed in a branch circuit or the end of subscriber line that meets the requirements. It realizes earth fault current, over fault current detection function, perfectly protects control function and “three teles” communication function (configuring communication backend software). After the equipment is installed and put into operation, it is able to automatically remove the single-phase earth fault of the controlled branch line and automatically remove the same short-circuit fault of the controlled branch line of the circuit breaker to improve the reliability and automotive level of power supply.
Outdoor intelligent vacuum load switch of TFLW34F – 12 is widely used in various distribution fields such as substations, industrial and mining enterprises, protection and control of urban and rural networks, automatic distribution networks and frequent operations of city and country, etc.
