Description
Technical field
The present invention relates to a kind of leakage relay, belong to earth leakage protective device.
Background technology
Leakage relay is that a kind of electric shock to line facility electric leakage and the person provides the device of protection.It can detect residual current, residual current and fiducial value is compared, and when residual current is greater than fiducial value, can sends switching signal control executive component and cut off the electricity supply, play a protective role.As electric equipment generation earth fault or human electric shock, leakage relay can control rapidly executive component and cut off the electricity supply, and prevents the generation of electric equipment damage and life injury accident.Therefore, pursuit and the objective of the struggle that the service behaviour of leakage relay, automaticity and protection range become many manufacturers how is improved.
Summary of the invention
The object of the invention is: provide a kind of rational in infrastructure, performance is more superior, automaticity is higher, the better leakage relay of result of use.
For achieving the above object, the technical solution used in the present invention is: a kind of leakage relay, comprise shell, be arranged on the circuit control panel of enclosure, zero sequence current mutual inductor and zero sequence current mutual inductor plug, the surface of described shell is provided with information data display screen, indicator light, button, mains switch, described indicator light comprises electric leakage indicator light and run indicator, described button comprises leak(age) test button and reset button, the bottom of described shell is provided with binding post, described shell is also provided with six driving switch, this leakage relay described adopts single-chip microcomputer to calculate and controls.
Related content in technique scheme is explained as follows:
In such scheme, in described information data display screen, be provided with charactron.
Because technique scheme is used, the present invention compared with prior art has following advantages:
Because the present invention is provided with six driving switch on shell, stir the electric leakage operating value of the adjustable leakage relay of six driving switch, electric leakage split time, exit and warning function from motion tracking shelves and electric leakage, expand protection range, decrease tripping operation number of times.
Control because leakage relay of the present invention adopts single-chip microcomputer to calculate, make relay stable motion in relatively rugged environment, easy to use, economical and practical.
Accompanying drawing explanation
Accompanying drawing 1 is the embodiment of the present invention one structural representation.
In above accompanying drawing: 1, shell; 2, zero sequence current mutual inductor; 3, zero sequence current mutual inductor plug; 4, information data display screen; 5, mains switch; 6, leak electricity indicator light; 7, run indicator; 8, leak(age) test button; 9, reset button; 10, binding post; 11, six driving switch, 12, charactron.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment one:
Shown in accompanying drawing 1, a kind of leakage relay of the present invention, this leakage relay adopts single-chip microcomputer to calculate and controls.It comprises shell 1, be arranged on the circuit control panel (not shown) of enclosure, zero sequence current mutual inductor 2 and zero sequence current mutual inductor plug 3, the surface of described shell is provided with information data display screen 4, indicator light, button, mains switch 5, indicator light comprises electric leakage indicator light 6 and run indicator 7, button comprises leak(age) test button 8 and reset button 9, charactron 12 is provided with in information data display screen 4, the bottom of shell 1 is provided with binding post 10, this leakage relay adopts single-chip microcomputer to calculate and controls, and shell 1 is also provided with six driving switch 11, is from left to right followed successively by 1, 2, 3, 4, 5, No. 6, stir No. 1 in six driving switch 11 and No. 2 switches in use, different electric leakage operating value 100mA can be set respectively, 300mA, 500mA, leaks electricity from motion tracking, stirs No. 5 in six driving switch 11 and No. 6 switches, can arrange different electric leakage operating value 30mA respectively, 50mA, 75mA, sudden change is exited, and stirs No. 3 in six driving switch 11 and No. 4 switches, can arrange different electric leakage 0.2S operate time respectively, 0.3S, 0.5S, 0.8S.Stir the upper and lower diverse location combination of 1,2,3, No. 4 switch in six driving switch 11, just can arrange " automatic catch ", under automatic gear situation, leakage relay can automatically according to the size of leakage current in circuit, select electric leakage operating value, its rule change is: after powering on, (or electric leakage action close a floodgate after) selects ear nail electric leakage action 1000mA automatically, if after 10 minutes in circuit leakage current be less than 50mA, then leakage relay is raised to 100mA shelves automatically; If leakage current is less than 150mA in circuit, then leakage relay rises to 300mA shelves automatically; If leakage current is less than 300mA in circuit, leakage relay rises to 500mA shelves.If leakage current is greater than 150mA in about 1 minute circuit, leakage relay rises to 500mA shelves automatically; if leakage current is greater than 300mA in circuit; then leakage relay rises to 1000mA shelves automatically. and this situation is specially adapted to Various Seasonal (as rainy season and dry season) leakage current and differs comparatively large, can ensure the different earth leakage protective requirements of rainy season and dry season.Stir the upper and lower diverse location combination of 1,2 or 3, No. 4 switch in six driving switch 11; also can arrange " warning shelves "; when being arranged on " warning shelves "; circuit has during electric leakage just reports to the police and display data; but be failure to actuate (namely representing that earth leakage protective exits), " electric leakage indicator light " 6 glittering (i.e. leakage-current alarm).
Above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
