Embodiment
Below in conjunction with accompanying drawing concrete mode of the present utility model is elaborated, embodiment of the present utility model is exemplary, only can not be interpreted as it is to restriction of the present utility model for explaining content of the present utility model.
The utility model is achieved through the following technical solutions:
With reference to illustrated in figures 1 and 2, transformer backup relaying device includes cabinet 1 and circuit board, includes display screen 2 on described cabinet 1 panel, button (4,41,42,43,44,45), menu Chinese character display screen 3; On the described circuit board protection module is arranged, memory module, communication interface, power module, the self-diagnostic function module, alarm module, described alarm module connects with the menu Chinese character display screen; Described self-diagnostic function module, memory module, protection module is linked in sequence and provide power supply by power module, and described self-diagnostic function module connects alarm module and communication interface simultaneously;
Described protection module includes composite voltage locking directional over-current protection unit, multiple platform voltage blocking over-current protecting unit, zero sequence direction over-current protecting unit, zero sequence over-current protecting unit, clearance zero sequence protection protected location.
Described power module comprises forceful electric power source module and weak mains module, and described forceful electric power source module and weak mains module are divided and be arranged.
Described communication interface includes ethernet communication interface 6 and RS232 serial line interface 5.
In the present embodiment, cabinet adopts cabinet design moistureproof, dustproof, anti-vibration.
What protection module and human-computer dialogue module were selected on the circuit board in the present embodiment is dual-cpu structure; certainly also can select in other embodiments single CPU structure; but stability is not as the technical program; the high-performance 32-bit CPU that selects; certainly can select in other embodiments the CPU of higher figure place; such as 64, all can for 128.Select simultaneously special-purpose DSP data to process.The CPU of human-computer dialogue module selects CPU now commonly used, and the stability of product and arithmetic speed are fully guaranteed.The defencive function of protection module realizes that by graphical and programming in logic the variation of function need not be revised system program simultaneously, and 32 cover protection definite values can independently be set, and makes protection realize that principle is transparent, reliable.
Described memory module is jumbo RAM and Flash memory, can record 8 to 50 record ripples reports, and the event number of record is no less than 1000 and have power down and keep function.
The serial line interface of panel configuration is the RS232 serial line interface, can carry out the logic can and also can be attached to computer and debug and analyze.
Clock and GPS hardware time setting circuit module are convenient to the total system clock synchronous.
Described power module comprises forceful electric power source module and weak mains module, and described forceful electric power source module and weak mains module are divided and be arranged.Such setting has excellent interference free performance, makes workstation platform not need other anti-interference module.
Described above is implementation technical scheme of the present utility model and operation principle, and those skilled in the art improves according to the technical program certainly, and this improvement still belongs to the protection range of the technical program.
