Description
Technical field
The utility model relates to power transmission and distribution field, relates in particular to a kind of integrated power supply.
Background technology
Electric power system control must possess safe and reliable control power supply.In power engineering, to control power supply and be divided into two classes, a class is DC power supply, a class is AC power.In transformer station, for the DC power system of the power supplies such as control, signal, protection, automatics and some actuator, be commonly referred to direct current operative power source.For the ac uninterrupted power supply system of the equipment power supplies such as computer monitoring, be commonly referred to ac control power supply, for switch, the DC power system of the communication equipment power supplies such as telemechanical, be called communication power supply, in existing electric power system, the general mode that adopts separate scattering device of above-mentioned these several control power-supply devices, equipment is provided by different suppliers, and adhere to different department's specialized managements separately: relaying protection specialty is responsible for the maintenance of direct current operative power source, Automation Specialty is responsible for the maintenance of ac control power supply, telemechanical communication speciality is responsible for the maintenance of communication power supply.So not only cause function repeated configuration, increase equipment is once invested; And the different maintenance work interface of each specialty, make the operational and administrative expenses of power-supply device high.In addition, the alternating current-direct current control power supply product being provided by different suppliers, does not have unified interface specification and watch-dog, and system data can not be shared, and is difficult to realize the network analysis of whole alternating current-direct current control power-supply device is safeguarded and integrated information management.Due to manufacturer's difference of each power-supply system, when power supply breaks down, or carry out power-supply system while safeguarding, need Duo Jia supplier's attendant to check to scene, attendant several hours soon, a couple of days could arrive slowly, the operating time having extended so, affect the power supply of equipment, for patrol officer, have equally problems.
Utility model content
The utility model aims to provide a kind of AC/DC integrated power supply, and simplified apparatus is cost-saving, maintains easily.
For achieving the above object, the utility model is realized by the following technical solutions:
The disclosed AC/DC integrated power supply of the utility model, comprise the AC power, electric power operation power supply, the rectifier that are connected on ac bus, be connected to inverter, chopper, charhing unit on DC bus, described charhing unit connects batteries, described chopper also connects communication power supply, also comprise monitoring unit, described monitoring unit connects chopper, communication power supply, inverter, batteries, described electric power operation power supply, rectifier also connect DC bus, and described chopper also connects communication power supply and charhing unit.
Further, described chopper comprises step-up DC-DC power supply and buck DC-DC power supply.
Further, described monitoring unit comprises data acquisition module, insulating monitoring module, switching value acquisition module, battery inspection module; Described data acquisition module is used for gathering integration power-supply system operational factor, described insulating monitoring module is for monitoring system bus and feed leg insulation parameter, described switching value acquisition module is used for gathering on off state data, and described battery inspection module is for detection of accumulator parameter.
The disclosed AC/DC integrated power supply of the utility model, simplified apparatus, cost-saving, can realize and concentrate group screen to the electric control system power supply of full station, meet the integrated turn-key project needs of power equipment; Can pass through centralized control apparatus, complete alternating current-direct current monitoring management scheme is provided, realize the population parameter monitoring management to transformer station's alternating current-direct current control power supply; Convenient for maintaining is safeguarded, failure rate and the maintenance management expense of the operation of reduction equipment greatly.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram;
Fig. 2 is the composition frame chart of monitoring unit.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, the disclosed AC/DC integrated power supply of the utility model, comprise the AC power, electric power operation power supply, the rectifier that are connected on ac bus, be connected to inverter, chopper, charhing unit on DC bus, charhing unit connects batteries, chopper also connects communication power supply, also comprise monitoring unit, monitoring unit connects chopper, communication power supply, inverter, batteries, electric power operation power supply, rectifier also connect DC bus, and chopper also connects communication power supply and charhing unit.
Further, chopper comprises step-up DC-DC power supply and buck DC-DC power supply, in order to meet different voltage requirements.
Further, as shown in Figure 2, monitoring unit comprises data acquisition module, insulating monitoring module, switching value acquisition module, battery inspection module.
Operation principle of the present utility model is as follows: when AC power is normal, give each rectification module power supply by Alternating Current Unit, alternating current is transformed to direct current by rectification module, and accumulators group charging on the one hand, provides normal working power through DC bus to DC load on the other hand; In the time of alternating current input power supplying fault outage, rectification module quits work, and is uninterruptedly powered to DC load by batteries.
Certainly; the utility model also can have other various embodiments; in the situation that not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
