At present, in the city, the hottest topic is intelligence, which is also a hottest topic in recent years, and this is not just a simple conversation to discuss, because related products have been produced, among which smartphones are typical products. Gradually, a lot of smart appliances and devices have appeared in our homes. One of the more novel wifi wall switch is more practical and generated, it joins the device of routing function, has a certain wireless connection effect, can control indoor lighting equipment from a distance, is a relatively easy to use product. Relatively speaking, the current urban circuit is also developing towards intelligence, in which the vacuum circuit breaker and some isolation switches have achieved the effect of working together. In use, they each have their own characteristics, among which the role of the high-voltage vacuum circuit breaker is to protect the circuit equipment from the impact of current overload.

The function of the high-voltage isolation switch is to temporarily isolate the circuit voltage when the power personnel need to repair and overhaul the circuit, and the effect is also relatively strong. At present, the two kinds of equipment can be used together, the effect is stronger, many times, due to the cooperation of the circuit breaker can make the use of the high-voltage disconnector more prolonged, for the circuit repair, the time is more abundant. This is also the preliminary development of intelligent circuits.
