Abstract
The utility model provides a voltage transformer which comprises a hexagonal bolt, a flat gasket, a primary terminal outgoing line, a fuse protector, primary windings, secondary windings, an iron core, an outer shell, a data plate, inserting pieces, channel steel bases and lead sealing bolts. According to the voltage transformer, an epoxy resin whole sealing pouring mode and a pillar-type structure are used, pollution resistance and moisture resistance are achieved, the size is small, weight is light, and thus the voltage transformer is suitable for being mounted at any position and in any direction. The fuse protector is further arranged so that a mutual inductor can be protected, when the voltage transformer is excited under nominal voltages, a one-second external short circuit can be borne, and zero damage is achieved.
Description
Technical field
The utility model relates to a kind of voltage transformer, particularly a kind of the voltage transformer that fuse is protected instrument transformer is housed.
Background technology
Electric power system often adopts alternating voltage, big current circuit that electric power is sent to the user for electric energy transmitting, can't directly measure with instrument.The effect of voltage transformer; exactly alternating voltage is dropped in proportion the numerical value that can directly measure with instrument; being convenient to instrument directly measures; provide power supply for relaying protection and automatics simultaneously; but exist the voltage transformer floor space huge on the market now; the equipment that uses is just many, and the investment funds are also a lot, maintenance on ordinary days be difficult to and also during short circuit instrument transformer be easy to damage.
Summary of the invention
The utility model is in order to address the above problem, provide a kind of safe, size is little, lightweight instrument transformer.Concrete, provide a kind of employing epoxy resin totally-enclosed cast, the voltage transformer of column support type structure.
The concrete technical scheme that the utility model is taked is:
A kind of voltage transformer comprises six square bolts, plain cushion, outlet terminal, fuse, winding, secondary winding, iron core, shell, nameplate, inserts, channel-section steel base and a lead sealing bolt;
The fuse upper end is connected to primary connection terminal, plain cushion and six square bolts and is connected with a winding by circuit; By poured with epoxy resin structure in aggregates, epoxy resin poured body was housing after secondary winding and a winding were assembled on the hollow iron core;
Outside studs with nameplate by the lead sealing screw;
The channel-section steel base is equipped with by inserts in the housing lower end.
Originally be that utility model adopts the totally-enclosed cast of epoxy resin, the column support type structure, anti-pollution and humidity, use suitable torrid areas, and instrument transformer does not need special maintenance, only needs the periodic cleaning surface contaminants, and because instrument transformer adopts totally-enclosed casting insulated, size is little, and is in light weight, is suitable for any position, the installation of any direction.The utility model also is equipped with fuse to be protected instrument transformer, when voltage transformer under rated voltage during excitation, can bear 1 second external short circuit and not damaged.
