Abstract
The utility model discloses a portable direct current power supply of a transformer substation. A display screen is arranged on a case panel; the display screen is electrically connected with a high-frequency switch power supply module by a controller; a rectifier module is electrically connected with the high-frequency switch power supply module; an accumulator group and the high-frequency switch power supply module are electrically connected with each other in parallel; and the high-frequency switch power supply module is also electrically connected with an alternate current input port and a direct current output port. The portable direct current power supply has the advantages of having two working modes of power supply mode and charging mode, meeting the requirements of detecting direct current elements, charging the accumulator and the like, being displayed in Chinese by liquid crystal, having friendly human-machine interface, convenient operation, and function of memorizing the running records, facilitating maintenance and check, being small in structure, moved conveniently, and capable of meeting the requirements of movable power supply of all transformer substations.
Description
Technical field
The utility model relates to the technical field of power supply, more particularly relates to the technical field of transformer station with the Portable DC power supply.
Background technology
At present, the control loop of power plant and big-and-middle-sized transformer station, protective relaying device and outlet loop thereof, signal circuit all adopt DC power supply.Therefore, direct current system is one of important system of power plant and transformer station, also is the basis of electric power system control, supervision.But only there are a cover direct current system in 110kV and following transformer station in the actual motion, according to " DL/T 724 electric power systems with accumulator direct current supply device operation and maintenance technical regulation " regulation, should regularly test to charger, storage battery.But can not cause the malfunction or the abnormal running of protective relaying device and automatics in the checkout procedure because of the direct current system reason.In addition, when setting up initial stage or enlarging, do not possess condition of power supply, then can sternly must influence the engineering construction test period owing to the direct current system imperfection in transformer station, power plant.
The utility model content
The purpose of this utility model be exactly provide a kind of in order to solve above-mentioned deficiency and be easy to carry, transformer station's Portable DC power supply that structure is small and exquisite, easy to use.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
Transformer station's Portable DC power supply, it mainly includes cabinet, display screen, and the controller, high-frequency switching power supply module, rectification module and the batteries that are installed in cabinet inside, display screen is installed on the panel of cabinet, display screen is electrically connected with high-frequency switching power supply module by controller, rectification module is electrically connected with high-frequency switching power supply module, batteries adopts mode in parallel to be electrically connected with high-frequency switching power supply module, also is electrically connected with alternating current input port and direct current delivery outlet on the high-frequency switching power supply module.
It also includes siren, and this siren is electrically connected with controller.
Described storage battery employing capacity is the analysing valve control type lead-acid accumulator battery of 12V for the 10Ah nominal value.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: it has electric source modes and two kinds of mode of operations of charge mode, can satisfy that the direct current components and parts detect and to requirements such as charge in batteries, this installs Chinese liquid crystal display, man-machine interface close friend, easy to operate, have the function of preserving log, be convenient to safeguard and check, small and exquisite, the conveniently moving of structure can satisfy the needs that move power supply between each transformer station.In regular to the direct current system of power plant and transformer station; if adopt the Portable DC power supply to power supplies such as protective relaying device, control loops; but the direct current system off-line check can effectively solve the contradiction of the reliable power supply of direct current system check and relaying protection and automatics like this.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a principle schematic of the present utility model.
Embodiment
By illustrated in figures 1 and 2, transformer station's Portable DC power supply, it mainly includes cabinet 1, siren, display screen 2, and the controller 3 that is installed in cabinet 1 inside, high-frequency switching power supply module 4, rectification module 5 and batteries 6, display screen 2 is installed on the panel of cabinet 1, also be provided with alternating current input port and direct current delivery outlet on cabinet 1 panel, this alternating current input port and direct current delivery outlet are electrically connected with high-frequency switching power supply module 4 respectively, display screen 2 is electrically connected with high-frequency switching power supply module 4 by controller 3, rectification module 5 is electrically connected with high-frequency switching power supply module 4, batteries 6 adopts mode in parallel to be electrically connected with high-frequency switching power supply module 4, siren is electrically connected with controller 3, when the utility model generation abnormal conditions, make alarm.
The utility model middle controller, high frequency switch power and batteries all can be bought on market and obtain, and wherein this controller is to be the control core with the single-chip microcomputer, adopts the C Programming with Pascal Language, have man-machine interface and logical collection function preferably.High-frequency switching power supply module adopts the high-frequency rectification technology, adopt output voltage, the electric current of single chip communication principle control high frequency switch power, to reach user's the voltage that requires, batteries is in parallel with high-frequency switching power supply module, and high frequency switch power is except that also carry out floating charge and boost charge to batteries to load provides DC power supply.When working under the situation that AC power is being arranged at the Portable DC power supply, provide DC power supply by the rectification principle to load by high frequency switch power, provide DC power supply by batteries to load in situation following time of AC-less power.Batteries employing capacity is the analysing valve control type lead-acid accumulator battery of 12V for the 10Ah nominal value, can not only storing electricity and can provide bigger impulse current for the user.
