In recent years, due to the spread of advanced industrial equipment such as computers and the sophistication of lifestyles due to the introduction of a wide variety of high-performance home appliances, today's social life has become increasingly dependent on electricity, resulting in construction power outages and breakdowns. Social awareness of power outages, regardless of whether they are power outages, is becoming increasingly severe. For this reason, today, in response to the above social needs, for example, in the event of a construction power outage, bypass cable cars loaded with power cables and mobile transformer cars are used to provide relief to customers. A so-called uninterruptible construction method has been developed that allows the supply of electricity to continue during a power outage, and has come to be used for construction power outages. and,
The mobile transformer used in the above-mentioned uninterruptible construction method is generally housed in an outer box that is loaded and fixed on a vehicle, and the main body of the transformer is housed together with the primary and secondary switches, voltage detection/phase detection equipment, etc. Outside the box, it is constructed by mounting high and low voltage cables, bypass cables, etc. on the vehicle, and when using it, connect the bypass cable vehicle and the mobile transformer vehicle at the construction site, and connect the power cable to the outside of the construction area. A bypass is applied from the mobile transformer to each customer on the high-voltage and low-voltage sides via cables to continue uninterrupted supply, and the line switch is opened to make the construction section voltage-free and construction work can be carried out safely. was going there.
