A low voltage regulator switch

Abstract

The invention discloses a low voltage regulating switch. The switch comprises a drive mechanism, a tap positon conversion component and a main assembling plate, wherein the drive mechanism comprises a drive motor, a gear transmission component, an energy storage spring component, a linear Geneva mechanism and a linear guide rail, and the tap position conversion component comprises a slide contact component, a static contact component, a middle insulating rack and an actuation arm; the rotation of the drive motor is transmitted to the energy storage spring component through the gear transmission component, the energy storage spring component stores energy and releases the energy when the stored energy reaches a certain amount to drive the linear Geneva mechanism to fast move on the linear guide rail, and the linear Geneva mechanism drives the slide contact component to move through the actuation arm to select corresponding static contacts on the static contact component so as to complete the conversion of corresponding tap positions. The switch has the advantages that the switch is mounted in a low voltage regulator, the voltage of the low voltage regulator can be increased and regulated while the size and shape of the low voltage regulator are unchanged, the low voltage problem caused by the long low-voltage power supply line in a power distribution network is solved effectively, the switch is good in mechanical action stability, the voltage regulating action can reach 50000 times without maintenance, and the switch is high in reliability.

Description

technical field [0001] The device relates to the technical field of electric power products, in particular, to a low-voltage voltage regulating switch. Background technique [0002] With the improvement of social economy and people's living standards, the requirements for power quality are getting higher and higher, especially the rapid growth of electricity consumption in rural areas. The problem of "voltage" is serious, the complaints of "low voltage" are extremely common, and it is imminent to solve the "low voltage" problem.

Problems solved by technology

[0003] At present, an effective measure for the problem of "low voltage" in rural areas: replace the non-excited distribution transformer with an on-load voltage-regulating distribution transformer that can automatically adjust the voltage under load to ensure the stability and qualification of the power supply voltage, but for In areas with weak grid structures, there are still low-voltage lines whose power supply length exceeds the economic power supply radius, "points and multiple lines are long", the line power supply radius is long, and the terminal voltage is low. The use of low-voltage voltage regulators can effectively solve the problem of low terminal voltage caused by long wire diameters

[0004] The current low-voltage voltage regulators all use electronic components such as contactors or thyristors, and multiple combinations form circuits to adjust the voltage, which has poor stability and low reliability. There is no voltage-regulating switch specially used for low-voltage voltage regulators.
