Embodiment Construction
[0011] The present invention mainly includes: a coil 1 , a tap changer 2 and an on-off device 3 . When the voltage regulator works in the straight-through gear, the switch device is used to cut off the current path of the voltage regulator coil according to the set procedure, and at the same time ensure that the coil does not break away from the grid.
[0012] figure 1 It is an electrical schematic diagram of the present invention, the current passes through A, the K1.1 switch of the switching device 3, the tap changer 2, the through gear of the coil 1, the K2 switch of the switching device 3, a, this state is equivalent to The voltage regulator is no-load, and the voltage regulator has no-load loss; figure 2 It is the electrical schematic diagram of the voltage regulator when K1.2 is closed during the operation of the opening and closing device according to the set program. In addition to passing through the above circuit, the current also passes through A, K1.2 switch and ...
