Technical field
The utility model relates to electric power Portable DC emergency power system, is specifically related to for power consumption equipment provides emergency power supply under DC power system, belongs to field of electrical equipment.
Background technology
DC power system is mainly used in power plant in electric power system, hydroelectric station and all kinds of transformer station; for the instrument in circuit-breaker switching on-off and secondary circuit, instrument, relaying protection, emergency lighting with breaker device even load can not provide working dc power incessantly; its the whether normal safe and reliable operation directly affecting electric power system; along with Automation of Electric Systems, computer control and the development of power electronic technology and the needs of actual field operation and maintenance, to the requirement also corresponding raising of DC power system safety and reliability.But due to field condition complexity, direct-flow electricity utilization apparatus is more, under DC power, the situation of electricity happens occasionally.In order to ensure the normal operation of direct-flow electricity utilization apparatus, need to enable emergency power supply during electricity under DC power system.Current direct current emergency power supply great majority need AC power input to work, and structure is simple, and many employing 220V batteries, volume is not easy to greatly on-the-spot application, and output voltage is single.For ease of using, be badly in need of improving direct current emergency power system.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is exactly select new integrated circuit technique, provides a kind of Portable DC emergency power system, is convenient to mobile and on-the-spot application.
For realizing the utility model object, the utility model adopts split-type design, reduces small product size, increases by two group storage battery groups, product be used when inputting without external ac power source, enhancing product performance, reducing costs.
Described Portable DC emergency power system comprises AC-DC conversion unit, DC boosting unit, alternating current-direct current information acquisition unit, with the monitoring unit of man-machine interface, two groups of 48V storage batterys, it is characterized in that: adopt split-type design, AC-DC conversion unit connects two groups of 48V storage batterys and DC boosting unit simultaneously, and DC boosting unit is connected with the monitoring unit with man-machine interface by photoisolator again; AC-DC conversion unit is connected with the monitoring unit with man-machine interface by photoisolator again; Alternating current-direct current information acquisition unit is by photoisolator and the monitoring unit separate connection with man-machine interface.
RS485 interface is selected in internal system communication, and upper machine communication selects RS232/RS485 two kinds of interfaces.
The power supply of each functional unit selects 220V to exchange input or 48V batteries is powered, and power requirement is comparatively flexible, whether can have 220V alternating current to select according to scene.
The utility model advantage is: out-put supply flexible form, split-type design, and volume is little, lightweight, be convenient to mobile, safe and reliable, performance is high, cost is low, very practical.
Accompanying drawing explanation
Fig. 1 is the johning knot composition of the utility model control circuit each several part.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Embodiment 1
Described Portable DC emergency power system comprises AC-DC conversion unit 1, DC boosting unit 3, alternating current-direct current information acquisition unit 4, with the monitoring unit 6 of man-machine interface, two groups of 48V storage batterys 2, it is characterized in that: adopt split-type design, AC-DC conversion unit 1 connects two groups of 48V storage batterys 2 and DC boosting unit 3 simultaneously, and DC boosting unit 3 is connected with the monitoring unit 6 with man-machine interface by photoisolator 5 again; AC-DC conversion unit 1 is connected with the monitoring unit 6 with man-machine interface by photoisolator 5 again; Alternating current-direct current information acquisition unit 4 is by photoisolator 5 and monitoring unit 6 separate connection with man-machine interface.
RS485 interface is selected in internal system communication, and upper machine communication selects RS232/RS485 two kinds of interfaces.
The power supply of each functional unit selects 220V to exchange input or 48V batteries is powered, and power requirement is comparatively flexible, whether can have 220V alternating current to select according to scene.
The utility model mainly provides emergency power supply for field electrical equipment during electricity under DC power system, samples and arranges, carry out management of charging and discharging to two groups of 48V batteries to parameters such as internal system electric current and voltages.
When scene possesses the input of 220V AC power, system adopts 220V Alternating Current Power Supply, through AC-DC conversion unit, 220V alternating current is converted to 48V direct current externally to export, meet the needs of on-the-spot 48V power consumption equipment, 48V direct current is that 220V direct current externally exports through DC boosting cell translation simultaneously, meets the needs of on-the-spot 220V power consumption equipment.When scene does not possess the input of 220V alternating current, powered to on-the-spot 48V power consumption equipment by two groups of 48V storage batterys, be that 220V direct current is powered to on-the-spot 220V power consumption equipment through DC boosting cell translation simultaneously.When not using this emergency power supply, can external 220V AC power through AC-DC conversion unit output 48V direct current, two group storage batteries be charged.When system works, monitoring unit with man-machine interface gathers the information such as electric current and voltage by alternating current-direct current information acquisition unit and is intuitively shown to user, user carries out management of charging and discharging by monitoring unit to two group storage batteries, and setting runs and output voltage current parameters, query warning record etc.
Internal system adopts RS485 interface to carry out communication, and between each communication interface, built in light electric isolution, greatly enhances antijamming capability, enhances the reliability of communication.
System adopts split-type design, reduces small product size and weight further.Every part has independent enclosure chassis, and bottom cabinet, pulley is housed, and is convenient to on-the-spot mobile.
