Abstract
The utility model disclose a SBW three-phrase compensated power voltage stabilizer. The SBW three-phrase compensated power voltage stabilizer comprises a box body, a servo motor, a controllable silicon switching tap and a compensated transformer. The servo motor is arranged at the bottom of the box body. Up-and-down parallel guide rails are mounted between two side plates of the box body. A plurality of positioning holes are formed in the guide rails. The compensated transformer is arranged on the guide rails through the positioning holes. An output shaft of the servo motor is connected with the compensated transformer through the controllable silicon switching tap. The SBW three-phrase compensated power voltage stabilizer is characterized in that louvered radiating windows penetrating the side plates of the box body are arranged on two sides of the box body and comprise through holes and filter screens, width of the near ends of the through holes is larger than that of the far ends of the through holes, and the filter screens are arranged at the near ends of the through holes. The controllable silicon switching tap is adopted to replace the traditional mechanical drive and carbon brush contact structure, thus the SBW three-dimensional compensated power voltage stabilizer is long in service life, small and light, high in efficiency, reliable, rapid in dynamic response and effective to protect electronic elements from damages by foreign matters.
Description
Technical field
The utility model relates to electric power voltage-stabilizer field, specifically, specially refers to a kind of SBW three-phase compensates electric voltage stabilizer.
Background technology
Along with the development of new and high technology, increasing high-accuracy load, to input power, particularly requires more and more higher to the precision of voltage regulation of alternating current input power supplying.But due to the existence of electricity supply and demand contradiction, the fluctuation of utility grid voltage is larger, can not meet the requirement of high-accuracy load, need between utility grid and load, set up the alternating current steady voltage plug of the wide voltage stabilized range of a high voltage stability precision.
Alternating current steady voltage plug form has a variety of, apply at present more three-phase AC voltage stabilizer, due to use be that mechanical drive and carbon brush contact regulate, thereby have that short, the linear property of mission life is poor, volume is heavy, efficiency is lower, the shortcomings such as poor reliability, dynamic response are slow.
In addition, because the through hole of the radiator window on existing voltage stabilizer casing adopts horizontal mostly, this kind and being in the defect when frequency converter: erect while installing when voltage stabilizer casing, tiny foreign material and dust easily enter in casing by radiator window, damage inner electronic component.
Utility model content
The purpose of this utility model is for deficiency of the prior art, provides a kind of SBW three-phase compensates electric voltage stabilizer, to address the above problem.
The technical matters that the utility model solves can realize by the following technical solutions:
A SBW three-phase compensates electric voltage stabilizer, comprises that casing, servomotor, controllable silicon switch tap and compensator transformer; Described servomotor is installed on the bottom of casing, upper and lower parallel guide rail is installed between the biside plate of casing, on described guide rail, offer some pilot holes, described compensator transformer is installed on guide rail by pilot hole, and the output shaft of servomotor switches tap by controllable silicon and connects compensator transformer; The both sides of described casing are provided with louvered radiator window, described louvered radiator window runs through the side plate of casing, louvered radiator window comprises through hole and screen pack, and the near-end width of described through hole is greater than the distal end width of through hole, in the proximal end of through hole, screen pack is also installed.
Further, the inside of described casing is provided with spring, and one end and the screen pack of described spring are connected and fixed, and the other end of spring connects the housing of compensator transformer, for described screen pack being pressed on to the side plate inwall of described casing.
Further, the inwall of described through hole offers ring groove, and described screen pack edge is positioned at ring groove and fixes by heat-conducting glue.
Compared with prior art, the beneficial effects of the utility model are as follows:
1, the utility model replaces traditional mechanical drive and carbon brush contact structure by adopting controllable silicon to switch tap, and long working life, lightweight and portable in volume, efficiency are higher, good reliability, dynamic response are fast.
2, the utility model is skewed radiator window by setting, dust and foreign material is outwards fallen along the sidewall tilting, and can directly not drop in casing, thereby avoid foreign material to damage electronic component.
