Description

Three-phase integrated formula voltage transformer
Technical field
The present invention relates to a kind of voltage transformer, concrete relate to a kind of three-phase integrated formula voltage transformer.
Background technology
Ferro resonance is the self-oscillatory a kind of form of electric power system; Be because the continuation that the saturation of ferromagnetic inductance such as transformer, voltage transformer causes, the phenomenon of amplitude resonance overvoltage; Though but the resonant process time is very of short duration, consequence is very serious.If working line has the weak place of insulation, then cause breakdown accident, therefore need a kind of novel voltage transformer of research and development to guarantee the fail safe and the reliability of whole power supply grid.
Summary of the invention
Defective in view of prior art exists the objective of the invention is to provide a kind of rationally distributed, the three-phase integrated formula voltage transformer of totally-enclosed cast.
For realizing above-mentioned purpose, the technical solution that the present invention adopted:
Three-phase integrated formula voltage transformer comprises A phase connection terminal, primary winding, secondary coil, iron core, secondary connection terminal, C phase connection terminal, mounting panel, connecting plate, B phase connection terminal, splicing ear, cable plug, the lead-out wire of primary winding, connection contact, fuse, high-voltage connection terminal.
A phase connection terminal, the C phase connection terminal of said three-phase integrated formula voltage transformer connect fuse respectively; Fuse is connected with primary winding lead-out wire one end through connection contact; The primary winding lead-out wire other end connects through the splicing ear on the connecting plate; The primary connection terminal is welded on an end of fuse, and the other end of fuse connects connection contact; B phase connection terminal connects fuse, and fuse is connected through the splicing ear on the connecting plate with the primary winding lead-out wire other end through connection contact; Cable plug is coated on the high-voltage connection terminal outside; Primary winding passes iron core, confirms the punching number of turn, and the secondary coil uniform winding is on iron core, and secondary coil connects the secondary connection terminal, and instrument transformer adopts the epoxide resin material cast to form.
Said high-voltage connection terminal comprises A phase connection terminal, B phase connection terminal, C phase connection terminal.
After adopting such scheme, compare the present invention with existing product and have following beneficial effect:
The present invention is rationally distributed, totally-enclosed cast, and climate adaptability is strong, has overcome the problem that the conventional voltage instrument transformer is prone to cause ferro resonance, has improved the reliability and security of power supply grid effectively.
