Abstract

The present invention is a distribution board with a panel transformer, comprising: a panel transformer, plural panel transformation units, a low voltage distribution board, a current transformer and a control unit, wherein the panel transformer includes a high voltage circuit-breaker for a power line, a transformer, and a low voltage circuit-breaker. The high voltage circuit-breaker for a power line is connected to external supply high voltage power. The transformer boosts supplied high voltage power passing through circuit breakers of branch power lines, and transforms high voltage power into low voltage power to supply power to a load. The low voltage circuit breaker is connected to a lower circuit breaker and a low voltage cable which are installed at the low voltage side of the transformer, and enables the connection and disconnection of low voltage supplied from the transformer with the load. The plural panel transformation units are configured through connection with the high and low voltage circuit breakers and the transformer wherein the high voltage circuit breaker supplies and cuts off power to the panel transformer. The low voltage distribution board is connected to low voltage power through low voltage cables, wherein low voltage power is supplied from the low voltage circuit breaker of each panel transformer that constitutes the panel transformation unit. The current transformer is installed at high and low voltage circuit breakers, and detects strength of the load current flowing in the cable connected to the high and low voltage circuit breakers. The control unit operates the high and low circuit-breakers by comparing the current strength detected by the current transformer with preset standard data value to enable connection or disconnection of each panel transformer with the load depending on the load variation. Therefore, the control unit is able to control the operating number of panel transformers.
