Description
Technical field
The utility model relates to a kind of leakage relay, belongs to earth leakage protective device.
Background technology
Leakage relay is a kind of line facility electric leakage and the person are got an electric shock the device of protection is provided.It can detect residual current, and residual current and fiducial value are compared, and when residual current is greater than fiducial value, can sends switching signal control executive component and cut off the electricity supply, and plays a protective role.When electric equipment generation earth fault or human electric shock, leakage relay can be controlled rapidly executive component and cut off the electricity supply, and prevents that electric equipment from damaging and the generation of life injury accident.Therefore service behaviour, automaticity and the protection range that, how to improve leakage relay becomes pursuit and the objective of the struggle of many manufacturers.
Summary of the invention
The purpose of this utility model 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 adopted in the utility model 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, on described shell, be also provided with six gear on-offs, described this leakage relay 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 utility model compared with prior art has following advantages:
Because the utility model is provided with six gear on-offs on shell, stir the electric leakage operating value, electric leakage split time of the adjustable leakage relay of six gear on-offs, from motion tracking gear with electric leakage is exited and warning function, expanded protection range, reduced tripping operation number of times.
Because the utility model leakage relay adopts single-chip microcomputer to calculate, control, make relay stable motion in comparing rugged environment, easy to use, economical and practical.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model embodiment mono-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, electric leakage indicator light; 7, run indicator; 8, leak(age) test button; 9, reset button; 10, binding post; 11, six gear on-offs, 12, charactron.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment mono-:
Shown in accompanying drawing 1, a kind of leakage relay of the utility model, 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, in information data display screen 4, be provided with charactron 12, the bottom of shell 1 is provided with binding post 10, this leakage relay adopts single-chip microcomputer to calculate and controls, and is also provided with six gear on-offs 11 on shell 1, is from left to right followed successively by 1, 2, 3, 4, 5, No. 6, stir in use No. 1 and No. 2 switches in six gear on-offs 11, different electric leakage operating value 100mA can be set respectively, 300mA, 500mA, electric leakage, from motion tracking, is stirred No. 5 and No. 6 switches in six gear on-offs 11, and different electric leakage operating value 30mA can be set respectively, 50mA, 75mA, sudden change is exited, and stirs No. 3 and No. 4 switches in six gear on-offs 11, different electric leakage 0.2S operate time can be set respectively, 0.3S, 0.5S, 0.8S.Stir the upper and lower diverse location combination of 1,2,3, No. 4 switch in six gear on-offs 11, just " automatic catch " can be set, under automatic gear situation, leakage relay can be 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, leakage relay is raised to 100mA gear automatically; If leakage current is less than 150mA in circuit, leakage relay automatic-ascending keeps off to 300mA; If leakage current is less than 300mA in circuit, leakage relay rises to 500mA gear.If in circuit, leakage current is greater than 150mA about 1 minute, leakage relay automatic-ascending keeps off to 500mA; if leakage current is greater than 300mA in circuit; leakage relay automatic-ascending keeps off to 1000mA. and this situation is specially adapted to Various Seasonal (as rainy season and dry season) leakage current and differs larger, 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 gear on-offs 11; also " warning barrier " can be set; when being arranged on " warning barrier "; when circuit has electric leakage, just report to the police and show data; but be failure to actuate (representing that earth leakage protective exits), " electric leakage indicator light " 6 glittering (being leakage-current alarm).
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection range of the present utility model.
