Abstract

The invention provides an intelligent switch which comprises a load switch, an operating mechanism, a position state indicator, an upper disconnecting switch, a lower disconnecting switch, a current transformer, a first potential transformer, a second potential transformer, an electronic switch, a charging module, a battery and an intelligent device, wherein the load switch is connected on a main circuit and located between the upper disconnecting switch and the lower disconnecting switch; the electronic switch is connected with the load switch in parallel; the current transformer is sleeved on a branch circuit where the load switch is located; and the load switch and the electronic switch are connected in parallel. The first potential transformer and the second potential transformer are respectively connected with the charging module and can charge the battery from two sides; the intelligent device is connected to the current transformer and the charging module, and the battery can provide direct current supply for the intelligent device and the operating mechanism; the battery is connected with the charging module; the operating mechanism is connected with the load switch; and the indicator is connected with the operating mechanism. The invention also provides a control method of the intelligent switch.

Description

technical field [0001] The invention relates to an intelligent switch suitable for a power distribution system, in particular to an intelligent switch capable of quickly detecting faults, restoring power supply and having small current impact. The present invention also relates to a control method for the above intelligent switch. Background technique [0002] In the power distribution system, three types of switches are commonly used to realize the automation of the power distribution system. The first is the recloser scheme, relying on the multiple reclosing of the recloser to identify the fault and isolate the fault. This method is simple to operate, but it has high requirements on the equipment, many times of inrush current, great harm, and the restoration of power supply is not complete; The second solution is to rely on the feeder automation terminal (FTU) and the distribution automation system. After the distribution network fails, it will be cut off by the protectio...
