The utility model relates to a many power output of modular make up voltage transformer, the mutual -inductor can become required friendship DC power supply with high -pressure side power switching over. Each power module installs on the voltage transformer body, and structure and voltage transformer secondary secondary winding is similar to 220V pin type fixing slot formula output joint phase -match, and the hasp is connected, and big small -size is the same for each module, and power inputoutput interface is unanimous, and the module dismouting is nimble simple and convenient, and the intermodule can be replaced each other. The module model is various, can become is similar to 220V power switching over variety of power such as is similar to 220V, is similar to 110V, 220V, 110V, 48V. The inside suitable air switch and the overvoltage protection that shoves of outfit that require of module. The user can match required power module model according to on -the -spot needs in a flexible way can. Through using the many power output of module combination voltage transformer, with the nimble apolegamy of the required power in scene to greatly reduced investment and fortune dimension cost.
Description
Technical field
The utility model relates to the utility model and relates to the power transfer module that a kind of Multiple coil voltage transformer exports several model.
Background technology
Box-type substation and distributed high-tension switch cabinet have now been widely used in the various occasions such as metallurgical steel rolling, industry light industry textile industry, industrial and mining enterprises, residential quarters, skyscraper and commercial field.Along with the iterative method of distribution automation system work; the remote collection of receiving end controller switching equipment service data is had higher requirement, in box-type substation and distributed high-voltage switch cabinet, all will have control operation power supply, energy storing of switch power supply, protective device power supply, data communication power supply etc.Existing combined voltage transformer generally all can provide alternating voltage (∽ 220V), PT metered voltage (∽ 100V) etc. to meet energy storage, control the operation demand of power supply and metered voltage.But the power supply way of output is limited by the product type of combined voltage transformer, if the later stage needs to reoffer DC power supply (-220V/110V), communication power supply (-48V), then only has and can realize by increasing rectification conversion electric power.Be necessary in this case to be optimized combination to various power supply, thus cost-saving, arise at the historic moment so the many power supplys of a kind of novel module export combination voltage instrument transformer.
Summary of the invention
The purpose of this utility model is to overcome existing deficiency, and provide the many power supplys of a kind of modular to export combination voltage instrument transformer, high and low pressure side is completely isolated, and fail safe is high; Structure is simple, safe and reliable, easy to use; Module is replaceable, simple and convenient, and O&M cost is low.
The technical solution of the utility model is achieved like this: the many power supplys of a kind of modular export combination voltage instrument transformer, are characterized in: it comprises voltage transformer, negative 220V modular power source 1, negative 110V modular power source 2, negative 48V module 3; Voltage transformer is wound with three groups of main windings and more than seven groups auxiliary winding, high-pressure side, three groups of main winding positions three-phase electricity winding; Have one group of auxiliary winding directly to export ∽ 110V to be exported by pin type fixed slot formula output interface, have more than three groups auxiliary winding directly to export ∽ 220V to be exported by pin type fixed slot formula output interface, export through negative 220V modular power source after having one group of auxiliary winding to export, export through negative 110V modular power source after having one group of auxiliary winding to export, export through negative 480V modular power source after having one group of auxiliary winding to export.
The utility model can effectively reduce cost, and provides reliable power supply, ensures that the normal safe of switch runs.
Accompanying drawing explanation
Fig. 1 is the utility model principle schematic.
In figure: 1---negative 220V modular power source; 2---negative 110V modular power source; 3---negative 48V modular power source.
Embodiment
The utility model comprises voltage transformer, negative 220V modular power source 1, negative 110V modular power source 2, negative 48V module 3; Voltage transformer is wound with three groups of main windings and more than seven groups auxiliary winding, high-pressure side, three groups of main winding positions three-phase electricity winding; Have one group of auxiliary winding directly to export ∽ 110V to be exported by pin type fixed slot formula output interface, have more than three groups auxiliary winding directly to export ∽ 220V to be exported by pin type fixed slot formula output interface, export through negative 220V modular power source after having one group of auxiliary winding to export, export through negative 110V modular power source after having one group of auxiliary winding to export, export through negative 480V modular power source after having one group of auxiliary winding to export.
1) voltage transformer body: main winding meets the alternating voltage basic demands such as metering, measurement, high-pressure side three-phase voltage is converted to 3 to 4 group ∽ 220V alternating voltages and exports by auxiliary winding, and configures pin type fixed slot formula output interface.
2) power module: be arranged on voltage transformer body, and structure and voltage transformer secondary auxiliary winding ∽ 220V pin type fixed slot formula output interface match, snap close connects, each block size is measure-alike, power supply input/output interface is consistent, module dismounting flexible and convenient, intermodule can be replaced mutually.Module model is various, ∽ 220V Power convert can be become the multiple power sources such as ∽ 220V, ∽ 110V ,-220V ,-110V ,-48V.Inside modules requires to be equipped with suitable air switch and overvoltage protection of shoving.User can according to the power module model of scene needs flexibly needed for apolegamy.
Export combination voltage instrument transformer by the replaceable many power supplys of module and substitute existing fixing winding type combination voltage instrument transformer, solve the on-the-spot demand to all kinds of operation power supply.
