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 ...

Abstract

The invention provides a line voltage regulator, which belongs to the technical field of power transmission and transformation. The present invention mainly includes: voltage regulator coil 1 , tap changer 2 and switch device 3 . The high-voltage incoming line and high-voltage outgoing line of the power supply line are connected to the high-voltage incoming line and high-voltage outgoing line of the coil of the line voltage regulator through the corresponding terminals of the switching device 3, or the switching device 3 is connected in series at the end of the coil of the line voltage regulator. When the voltage regulator works in the straight-through gear, it cuts off the current path of the coil of the line voltage regulator, eliminates the no-load loss of the line voltage regulator in the straight-through gear, reduces the loss of the power supply line during the transmission process, and reduces the operating cost of the power supply line.

Description

technical field [0001] The invention provides a line voltage regulator (hereinafter referred to as a voltage regulator), which belongs to the technical field of power transmission and transformation. Background technique [0002] At present, the known voltage regulator operates in a no-load state when working in the straight-through gear, which wastes energy. Contents of the invention [0003] The technical solution provided by the invention is that when the voltage regulator works in the straight-through gear, the voltage regulator exits the no-load state, which eliminates the no-load loss of the voltage regulator, saves energy, and reduces the operating cost of the line. [0004] The present invention mainly includes: a voltage regulator coil 1 , a tap changer 2 , and an on-off device 3 . [0005] The object of the present invention is achieved in this way: the voltage regulator mainly includes a coil 1 , a tap changer 2 and an on-off device 3 . When the voltage regula...
