Specifications
The singlephase oil- filed pole-mounted distribution transformers are also suitable for light and diversified power applicationsSummarization:
The single-phase oil- filed pole-mounted distribution transformers are specifically designed for the decentralization distribution network of servicing residential overhead distribution loads of town and countryside. They are also suitable for light and diversified power applications. These transformers are designed for the application conditions normally encountered on electric utility power distribution systems.
Offer 2 basic transformer types and 2 kind metal core type conventional type and complete self protecting type. And for the transformer core, 2 type materials are available: C.R.G.O wound core and amorphous metal core.
Standards:
IEEE C57.12.00 IEEE C57.12.20
ANSI C 57.12.00 IEEE C57.12.20 IEC 76 GB10318
Feature of outer structure:
- Cover mounted high voltage porcelain bushings with eyebolt terminals are mounted on flat embossments on the cover and have undercut gasket seats for improved sealing. The eyebolt connectors are cast bronze plated with tin to accommodate both aluminum and copper conductors.
- One –piece fasten ring prolongs the life of the transformer, facilitated inspection and maintains even pressure around the entire rim, it combines with a specially formed tank rim, draw cover and gasket to form an effective seal which will not deteriorate with age.
- Low voltage tank-wall bushing terminals are clamp type and tinplated.
- Tank is equipped with self-sealing pressure release device.
- Support lugs, welded to the tank, conform to ANSI standards are made of hot-rolled steel.
- Tank is supplied with a tank grounding bolted ring-type connector suitable for use with copper or aluminum.
Conventional type:
The transformer is cylinder sealing structure. Each one is fixed with grounding devices, hooks, support lug which conform to ANSI standard, and one or two high voltage bushing on the cover, low voltage bushing on the wall of the tank and eyebolt connecting terminals. High voltage taps should be connected when the power is cut off.
Complete self-protected type:
This transformer is complete self-protected type. Which can protect itself from thunder and lighting, short circuit and protect the transiting and distribution line from current failure because of self-malfunction.
Except from some similarities such as: cylinder tank, hooks, lifting lugs, grounding devices, nameplates core and winding with conventional type. This type of transformer has characteristic and devices as follows: one or two high voltage bushings in which there is fuse:
One or two arresters, on the wall of the tank, whose top end is near to the high voltage bushing, and connected to the bushing by copper strip;
One secondary breaker switch above the winding inside tank, and here are operating handle, overload reset and signal light. Low voltage bushing induced from the wall of the tank, grounding device is fixed to position X2.
Core: C.R.G.O core and amorphous metal core can be chosen.
