The voltage transformer consists of a high-voltage contact, a high-voltage fuse, a high-voltage lead terminal, a high-voltage coil, a low-voltage coil, an iron core and a mounting plate. Two ends of the high-voltage fuse are respectively connected to the high-voltage contact and the high-voltage lead terminal, the high-voltage lead terminal is connected to the high-voltage coil, an iron core is arranged between the high-voltage coil and the low-voltage coil, and the lower end of the iron core is fixed by the mounting plate.
Description
Technical field
The utility model relates to the instrument transformer field, concretely, relates to install in a kind of handcart dedicated potential transformer.
Background technology
Voltage transformer is the equipment of measuring voltage, electric energy in electric power system or the electric control system, convenient in order to realize switch cubicle miniaturization and repair and maintenance, usually voltage transformer is assembled into the profile of metering handcart, the physical dimension of various functional parts all has strict restriction, otherwise can influence the overall performance of metering, and installation and maintenance are loaded down with trivial details, electric connecting part is on the high side, increased many qualifying points, buried potential safety hazard to operation.
Summary of the invention
The purpose of this utility model provides in the composite type handcart of a kind of totally-enclosed cast back dedicated potential transformer is installed.
The utility model is made of high-voltage contact, high-tension fuse, high-voltage connection terminal, high-tension coil, low-voltage coil, iron core, mounting panel; The high-tension fuse two ends connect high-voltage contact and high-voltage connection terminal, and the high-voltage connection terminal connects high-tension coil, is iron core between high-tension coil and the low-voltage coil, and the lower end has mounting panel to fix.
Described iron core is a loop configuration, is that the high-quality cold-reduced silicon sheet rolls and forms, and one time winding is all insulation.
Dedicated potential transformer is installed in the described novel handcart has the fuse protection.
Advantage of the present utility model is:
1, volume is little, climate adaptability is strong, and anti-industrial frequency resonance can overexcitation not burn;
2, transformer iron core loop configuration adopts the high-quality cold-reduced silicon sheet to roll and forms, and one time winding is all insulation.
3, have the fuse protection, improve line security; Being suitable for 35kV handcart cabinet and small size switch cubicle uses.
