Abstract
The utility model relates to the field of transformers, and particularly discloses a combined-type voltage transformer. The combined-type voltage transformer consists of a contact arm, a fuse, a high-voltage leading-out terminal, a high-voltage coil, a low-voltage coil, an iron core, a secondary wiring terminal and a mounting plate, adopts a fully closed structure through casting, and is suitable for being used in an AC 50hz or 60hz electric power system with a rated voltage of 10Kv or below of an indoor device for voltage measurement, electric energy metering and relay protection. The fully-closed cast combined-type voltage transformer has the advantages of small size, strong climatic adaptation, power frequency resonance resistance and avoidance of overexcited burnout; the iron core of the transformer adopts a ring structure and is wound by a high-grade cold-rolled silicon sheet; all primary windings are all-insulated; the fuse is provided for protection, so as to improve the circuit safety; and the combined-type voltage transformer is applicable to handcart cabinets and small-sized switch cabinets.
Description
Technical field
The utility model relates to field transformer, concretely, relates to a kind of composite type voltage instrument transformer.
Background technology
Electric power system is because after the ground connection in various degree, instrument transformer generation ferro resonance and burning in a large number not only causes very big waste also the user to be brought about great losses for the user.
Summary of the invention
In order to overcome above deficiency, main purpose of the present utility model is providing a kind of combined electrical pressure type instrument transformer, and it has when 100% earth fault, still can normally move for a long time, produces 100 volts of voltages simultaneously and makes the condenser action.
The utility model is by contact arm, fuse, and the high pressure leading-out terminal, high-tension coil, low-voltage coil, iron core, the secondary connection terminal, mounting panel is formed; Low-voltage coil is wrapped on the insulation iron core, on low-voltage coil, twine high-tension coil at a certain distance again, on high-tension coil, draw the high pressure leading-out terminal, high pressure leading-out terminal and high-tension coil are welded to each other, high pressure leading-out terminal and fuse interconnect, fuse is connected with contact arm, and low-voltage coil welds mutually with the secondary connection terminal.Contact arm, fuse, the high pressure leading-out terminal, high-tension coil, low-voltage coil is fixed into the totally enclosed type type to each parts through pouring type after the above-mentioned connection of process unshakable in one's determination.The structure of instrument transformer adopts the pouring type full-enclosed structure.Mounting panel is connected by screw with pour mass.
The utility model is suitable for exchanging 50Hz, does voltage measurement in the electric power system of 60Hz rated voltage 10Kv and following inside plant, electric energy metrical and used for relay protection.The utility model is a totally-enclosed cast back composite type; volume is little; climate adaptability is strong, and anti-industrial frequency resonance can overexcitation not burn; instrument transformer loop configuration unshakable in one's determination; adopt the high-quality cold-reduced silicon sheet to roll and form, one time winding is all insulation, has the fuse protection; improve line security, be fit to handcart cabinet and small size switch cubicle and use.
