Abstract
The utility model relates to an AC-DC-AC combined power source converting device, which is suitable for the unit along the electrification railway to get working power source from the pulling line and belongs to the electrical device technical field. The utility model realizes the purpose of splitting the single phase alternating current into three phase sine wave alternating current through the arrangement of the single phase constant voltage rectifier module and the connected three phase inverted power supply module, and the output voltage is constant within 5 percent under the situation that the single alternating voltage changes within positive and negative 20 percent, thus satisfies the relative unit along the electrification railway to directly get the working power source from the pulling line in the most economical and convenient way, which is especially beneficial to the remote areas, the economic less-developed or population sparse areas along the electrification railway and has evident economic benefits and social benefits.
Description
Technical field
The utility model relates to a kind of friendship orthogonal integrated drive generator conversion equipment, is applicable to that electric railway unit along the line obtains working power from draught line, belongs to the electrical equipment technical field.
Background technology
Now, the electric railway development of China is very fast, along with the electric railway development, a lot of websites and relevant departments must be set along the line, and these websites and relevant departments all need to use three-phase alternating current, in economically developed relative intensive area with population, the various places power department fully can the construction of line provides power supply for these websites and relevant departments, and in area underdeveloped and that population is sparse, if power department aims at these websites and relevant departments' construction of line, obviously be both uneconomical, also impossible.Most economical, the way of most convenient is to obtain working power from draught line, and be the single-phase high voltage alternating current on the draught line, become the single-phase high voltage alternating current low-pressure single-phase alternating current electricity can realize fully through the transformer transformation, but the low-pressure single-phase alternating current electricity scope of application is very narrow, and this single-phase alternating current change in voltage amplitude is very big, more needs three-phase alternating current with electric loading, be reverse into after the rectification of stabilized voltage power supply single phase alternating current (A.C.) at present and be reverse into three-phase alternating current after single phase alternating current (A.C.) and the three-phase alternating current rectification and all have very mature technique, but also single phase alternating current (A.C.) is not split into the conversion equipment of three phase sine alternating current wave.
Summary of the invention:
The purpose of this utility model provides a kind of friendship orthogonal integrated drive generator conversion equipment, solve only to have at present and be reverse into the situation that is reverse into three-phase alternating current after single phase alternating current (A.C.) and the three-phase alternating current rectification after the rectification of stabilized voltage power supply single phase alternating current (A.C.), realize single phase alternating current (A.C.) is split into the three phase sine alternating current wave.
The purpose of this utility model is achieved through the following technical solutions, a kind of friendship orthogonal integrated drive generator conversion equipment, it is characterized in that described conversion equipment is made of the output connection three phase inverter module of single-phase constant voltage rectification module, the input termination source end of single-phase constant voltage rectification module, the output of three phase inverter module connects threephase switch.
Can insert storage battery and single-phase switch between single-phase constant voltage rectification module and the three phase inverter module.
The input of single-phase constant voltage rectification module connects the source end after can connecing the voltage stabilizing reactance transformer.
The utility model is by being provided with the three phase inverter module that single-phase constant voltage rectification module is connected with it, realized single phase alternating current (A.C.) is split into the purpose of three phase sine alternating current wave, and it is constant in 5 percent to change under positive and negative 20 percent the situation output voltage at single phase alternating current (A.C.) voltage, electric railway relevant unit along the line is most economical, most convenient ground directly obtains working power from draught line thereby satisfied, be particularly conducive to electric railway outlying district along the line, underdeveloped and area that population is sparse, have remarkable economic efficiency and social benefit.
