Right and left mutually changing is to be very easy to easy thing, but liquid soaking transformer phase angle quick switching device, can not carry out phase in outside
The exchange answered, even can be with, it is also necessary to all leads are led into case lid, corresponding sleeve pipe quantity is more, and volume is big, very not
It is easy to the integral arrangement of case lid, and the problems such as external cabling is random, powered part is exposed, inconvenient for operation is present, exists larger
Potential safety hazard.Two, its structural integrity is poor, and mechanical strength is low.Construction package is more, causes finished product overall volume larger,
Many inconvenience are brought when being assembled in transformer.Three, insulation effect is poor.Once there is water immersion, internals is easily lost by scale, together
When potential safety hazard be present.
The content of the invention
It is an object of the invention to provide a kind of small volume, the phase shifting angle that insulation effect is good and simple to operate, reliable
Quick switching device.
The present invention adopts the technical scheme that to reach above-mentioned technical purpose：A kind of liquid immersion type phase-shifting transformer phase shift
Angle quick switching device, including upper lid, sealing ring and epoxy resin multicore cylinder, epoxy resin multicore cylinder is interior to set multiple conductions
Stake, it is characterised in that：It is integrally formed between epoxy resin multicore cylinder and multiple conductive stakes using poured with epoxy resin；Phase shift inserted block
It is connected with Quick connector plug by conductor, after connection, the two is integrally formed using poured with epoxy resin；Conductive stake is with quickly connecting
The position that plug is connected sets watchband-shaped contactor, is connected by watchband-shaped contactor wire jumper；After shifting to inserted block extraction, rotation 120
Degree is again insertable into conductive stake, you can realizes the conversion of phase angle.
The material of described conductive stake is high-quality oxygen-free copper.
Injection waterproof insulation liquid in the epoxy resin multicore cylinder, for the insulation between conductive stake and snap joint and close
Envelope.
The lower end of the conductive stake is contacted transformer lead with conducting surface by bolt by thread forms, reaches contact
Firmly it is not easy the purpose loosened.
The advantage of the invention is that：First, epoxy resin multicore cylinder of the present invention is with being arranged at leading in the multicore cylinder
Electric stake, it is an entirety by poured with epoxy resin, insulation distance is small, good insulation preformance, high mechanical strength, greatly reduces fast
The volume of fast conversion equipment, it is easy to assemble use in transformer.Second, shift to inserted block and use epoxy resin with fast connector
The mode of cast is integrally formed, and improves overall operability, and improves insulating properties, and use is safer.3rd,
Conductive stake sets watchband-shaped contactor with the position that Quick connector plug is connected.The advantages of watchband-shaped contactor, is to connect with conductive stake
Contacting surface product is big, and current-carrying capacity is good, and elasticity is good, can repeatedly plug.4th, shift to after inserted block extracts, 120 degree of rotation is again insertable into leading
In electric stake, you can realize the conversion of phase angle.By way of rotation, change the direction of phase shift inserted block, conveniently realize phase shift angle
Right and left mutually changing function.5th, the globality of each functional part, outside has upper lid and sealing ring to carry out sealing protection, has simultaneously
There is waterproof insulation liquid, reach effect that is multi-layer sealed and improving insulating properties, degree of protection IP68.
In brief, quick switching device of the invention, there is small volume, good insulation preformance, simple to operate, described device
Interior phase shift inserted block, is molded by poured with epoxy resin, and high mechanical strength, current-carrying capacity is big, can be plugged repeatedly, and wiring is concise, behaviour
Make simply, securely and reliably.
