Abstract
The invention relates to the field of transformers, in particular to a combined voltage transformer. The combined 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 an installing plate. The combined voltage transformer adopts a casting-mode fully-enclosed type structure. The combined voltage transformer is suitable for voltage measurement, electric energy metering and relay protection in an electric system of an indoor device with the alternating current being 50Hz or 60 Hz and the rated voltage being equal to or less than 10kV. The combined voltage transformer is in a combined type after fully-enclosed casting, is small in volume and strong in climatic adaptation, resists power frequency resonance, can not be burnt by over excitation, adopts a ring-shaped structure for the iron core, is made by winding high-grade cold-rolled silicon steel sheets, realizes full insulation of primary windings, has the fuse protection, improves the line safety and is suitable for being used by a handcart cabinet and a small-volume switch cabinet.
Description
Technical field
The present invention relates to field transformer, concretely, relate to 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 invention is providing combined electrical pressure type instrument transformer, and it has when 100% earth fault, and still normally operation for a long time produces 100 volts of voltages simultaneously and makes the condenser action.
The present invention 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; Be wrapped in the low-voltage insulation coil on the insulation iron core; On the low-voltage insulation coil, twine the High-Voltage Insulation coil at a certain distance again; On the High-Voltage Insulation coil, draw the high pressure leading-out terminal, high pressure leading-out terminal and High-Voltage Insulation coil are welded to each other, and high pressure leading-out terminal and fuse interconnect; Fuse is connected with contact arm, and low-voltage coil welds with the secondary connection terminal mutually.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 through screw with pour mass.
The present invention 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 present invention is a totally-enclosed cast back composite type, and volume is little, and climate adaptability is strong; 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.
