YD SERIES OF HV TESTING TRANSFORMER
I. Introduction of Product
Transformer for high voltage test produced by our company is the main equipment of insulation strength test for various kinds of products such as power supply unit, switch gear, insulation tools and materials etc.
This series of products is of compact structure and good versatility. It is convenient to use this series of products and is especially suitable for on-site check of insulation performance of various kinds of electric equipments.
II. Characteristics of Product
The iron core of this series of products is of single phase. As for fastening method, epoxy plate or steel material will be used as clamping piece and the traditional core-through bolt is stopped to use. The coil is of concentric cylinder multi-layer tower type. Low voltage coil is on inner side and high voltage coil is on outer side. Meter coil is the 100V tap of high voltage end.
The design of transformer cover is suitable for the structure of cassette mechanism. High voltage silicon rectifier stack in the testing transformer （for both alternating current and direct current） is sealed within the high voltage tube with special process.
