Abstract

The invention provides a spiral contact voltage regulator. The spiral contact voltage regulator comprises a support, an iron core, a coil bobbin and a coil, wherein the iron core is sleeved with the coil bobbin, and the coil is spirally wound around the coil bobbin. The coil bobbin is installed on the support, and the coil bobbin and the support are in axial limiting and can be matched in a rotating mode in the circumferential direction. The support is provided with an operating mechanism used for driving the coil bobbin to rotate. A fixed electric brush carrier is installed on the support and provided with a fixed electric brush. The fixed electric brush is located on one side of the coil bobbin and makes tight contact with the circumferential side of the coil. A movable electric brush carrier is arranged outside the coil and provided with a movable electric brush, the head of the movable electric brush is provided with a slide groove, and the coil is embedded in the slide groove. The movable electric brush and the rotating coil are in longitudinal slide fit. According to the spiral contact voltage regulator, the problem that electric brushes bear two to three turns of voltage is eliminated by simply pressing one turn of coil on the corresponding electric brush; the electric brushes are made of copper or copper alloy, and therefore the voltage regulator will not be short-circuited; besides, the contact resistance and consumption between the voltage regulator and the electric brushes are lowered, and the voltage regulator breaks through the technical bottleneck that the electric brushes need a large current.

Description

technical field [0001] The invention relates to a voltage regulator, in particular to a spiral contact voltage regulator. Background technique [0002] Voltage regulators are widely used in various fields, but now all are contact voltage regulators with brushes sliding on the grinding surface of the coil, and the purpose of adjusting the voltage is achieved by changing the turns ratio of the coil (see Image 6 , Figure 7). [0003] The contact voltage regulator is used for continuous stepless regulation of the AC load voltage and is the core component of the automatic voltage regulator. Due to the contact voltage regulator currently used, the brushes are pressed against the grinding surface of the coil to move. In order to achieve continuous stepless regulation, it must contact and press two to three turns at the same time (see Figure 8 , Figure 9 ), then the brush will bear two to three turns of voltage, the greater the power of the voltage regulator, the greater the tu...
