Technical field
The utility model relates to electrical protection apparatus, especially a kind of general digital electric protection device.
Background technology
Digital power protection is by judging the operational factor analysis of electric system; in some cases relay protection is carried out to circuit, transformer, motor and electric capacity with protection; existing digital power protection is mainly high-voltage electric power system power fault protection application design; volume is larger; be not suitable for the installation by adhering of minitype high voltage switchgear or low voltage complete set; functional redundancy, wiring is loaded down with trivial details.
In order to protect low-voltage power system; low-voltage variation system is designed with in existing industry; traditional low-voltage variation system; although structure is simple; but insufficiency of function, can not to adjust adjustment at scene, does not have communication interface; and site installation test is difficult, the requirement of user to Premium Features can not be met.
In addition, existing product function is all design for embody rule, as: transformer, motor, circuit etc. must be divided into according to different object of protections, and versatility is not enough, can not meet the rig-site utilization demand of user's quite flexible;
And the electric protection device of existing high-voltage electric power system is not suitable on low-voltage equipment; reason following points: a. product own vol is excessive; can not be embedded in the control box special body of field apparatus; b. this series products is generally according to method of operation parameters or the function of medium voltage network; do not consider the operating condition that low-voltage equipment is special; defencive function is made to there is larger defect; c. too high own power loss; product is generated heat more serious; when improper ventilation, there will be disabler.
Utility model content
The utility model proposes a kind of general digital electric protection device, solve the problem that cannot embed specialized control equipment, versatility and less stable in prior art.
The technical solution of the utility model is achieved in that
This device comprises set of circuits plate, described circuit board comprises an embedded controller, embedded controller is connected with signal acquisition module, described signal acquisition module is connected with signal input terminal, described embedded controller is connected with load module, display module and control signal lead-out terminal, described circuit board is located in a metal cabinet closed, described casing comprises a panel and is located at the housing at panel rear, housing is made up of rear end face and side plate, described load module and display module are located on panel, described signal input terminal and control signal lead-out terminal are located on the rear end face of housing.
Preferably, the length of described panel is 122.54mm ± 0.01mm.
Preferably, the 75.5mm ± 0.01mm of the width of described panel.
Preferably, the height of described casing is 60.5mm; The width of described casing is 116.5.
Preferably, the length of described casing is 104.5mm.
Preferably, the length of described casing comprises signal input terminal and control signal lead-out terminal length.
Preferably, described display module comprises display screen and pilot lamp.
Preferably, described load module is one group of button.
Owing to have employed technique scheme, general digital electric protection device of the present utility model is carrying out process and the transmission of signal by embedded controller, the control software design of the protective device of existing all kinds of special equipment and circuit can be write in this embedded controller, thus better versatility can be provided; And installed by closed box, be applicable to the installation by adhering of minitype high voltage switchgear or low voltage complete set, complete function, wiring is succinct.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model modular structure schematic diagram;
Fig. 2 is the utility model external structure schematic diagram;
Fig. 3 is the utility model back structures schematic diagram;
Fig. 4 is the utility model side structure schematic diagram.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As Figure 1-3, general digital electric protection device of the present utility model comprises set of circuits plate 1, described circuit board 1 comprises an embedded controller 2, embedded controller 2 is connected with signal acquisition module 3, described signal acquisition module 3 is connected with signal input terminal 4, described embedded controller 2 is connected with load module 5, display module 6 and control signal lead-out terminal 7, described circuit board 1 is located in a metal cabinet 8 closed, described casing 8 comprises a panel 81 and is located at the housing 82 at panel rear, housing 82 is made up of rear end face 821 and side plate 822, described load module 5 and display module 6 are located on panel 81, described signal input terminal 4 and control signal lead-out terminal 7 are located on the rear end face of housing.
On the design area of panel, in the present embodiment, the length of described panel 81 is 122.54mm ± 0.01mm; 75.5mm ± the 0.01mm of width.
In order to match with the standard installation position of minitype high voltage switchgear or low voltage complete set, in the present embodiment, the height of described casing 82 is 60.5mm; The width of described casing 82 is 116.5mm; The length of described casing 82 is 104.5mm.
