Embodiment 1

[0054] like figure 1 As shown, the traditional voltage regulator is mainly composed of the following parts, including a voltage regulator housing 90, a dial 93, a pointer, a carbon brush and a bracket 94, an annular iron core 95, a wiring panel 96, a central shaft 97, and an annular A coil winding is wound on the iron core 95 , and the upper surface of the coil winding is provided with a polished surface, which is used to realize the contact with the carbon brush to adjust the voltage.

[0055] like figure 2 As shown, in the present invention, a single coil wound on the annular iron core 95 in the prior art is arranged as a plurality of groups of segment coils 4 end-to-end adjacently wound on the annular iron core 95, in order to ensure the continuity of the voltage and all The coils are wound in the same direction. There are at least two sets of segment coils 4 , and the segment coils 4 include adjustment coils 41 and tie coils 42 that wind in the same direction. like f...

Embodiment 2

[0075]Based on the structure of the first embodiment, the dial 93 is used as the upper cover plate of the voltage regulator housing 90 , and the wiring panel is arranged on the voltage regulator housing or the dial. Buttons, liquid crystal displays and controllers are arranged on the wiring panel or the dial, so pointers and scales may not be arranged on the dial. The controller collects the output voltage of the voltage regulator and displays it on the liquid crystal display, and at the same time, the controller adjusts the working state of the voltage regulator through the input of keys. like Figure 7 As shown, the collection of voltage and current can be realized by setting the voltage transformer YT and the current transformer LH. In the field of electrical metering, the technology of collecting voltage and current through a microcomputer relay protection device is very mature, and will not be repeated here. In addition, a limit device and a limit pin 2 are also included...

Abstract

The invention relates to the field of electrical equipment, and particularly relates to a self-coupling voltage regulator capable of being used in partitioned mode. The self-coupling voltage regulatorcomprises a voltage regulator shell, a pointer, a dial, a carbon brush, a bracket, an annular iron core, a wiring panel, and a central rotating shaft, wherein the dial is embedded into the upper partof the voltage regulator shell. The self-coupling voltage regulator further comprises segmented coils and a change-over switch. The lead-out points of different segmented coils are used as the lead-in points of a power supply through a controller, so that the adjustment of the output range of the segmented coils is realized. The self-coupling voltage regulator has the beneficial effects of beingsimple in structure, automatic in control and capable of effectively prolonging the service life of the voltage regulator.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a self-coupling voltage regulator that can be used in different regions. Background technique [0002] The functions of the voltage regulator and the transformer are similar, and both are devices for voltage conversion. The difference between the voltage regulator and the transformer is that the secondary terminal of the voltage regulator has the function of continuously adjustable voltage output. [0003] The traditional voltage regulator is mainly composed of the following parts, including the voltage regulator housing, knob, pointer, dial, carbon brush and bracket, annular iron core, wiring panel, central shaft, and a coil is wound on the annular iron core winding. The upper surface of the coil winding is provided with a polished surface, and the polished surface is used to realize the contact with the carbon brush and thus achieve the function of adjusting the voltage. T...
