Description
Technical field
The present invention relates to electric energy metrical product intelligent ammeter use, particularly relate to a kind of intelligent electric meter magnetic latching relay.
Background technology
Along with the development of intelligent electric meter technology, function is increasingly extensive.In numerous intelligent electric meters, magnetic latching relay, because cost is low, performance is good, reliability is high and be widely used, is especially applied to the control system of switching on or off electricity of electric energy meter.
Traditional intelligent electric energy meter magnetic latching relay internal structure is unreasonable, there is potential safety hazard.Therefore, how providing a kind of more reasonable structure, assembling more convenient, that fail safe is higher, cost is lower magnetic latching relay is technical issues that need to address.
Summary of the invention
In view of this, the invention provides a kind of intelligent electric meter magnetic latching relay, solve the problem that internal structure is unreasonable, there is potential safety hazard.
For solving the problem, technical scheme provided by the invention is as follows:
The invention provides a kind of intelligent electric meter magnetic latching relay, comprising: control the upside that red line is arranged at drain pan; Control the upside that black line is arranged at drain pan; Coil unit is arranged at the top of described relay; Moving plate unit is arranged at the bottom of described relay; Still unit is arranged at the bottom of described relay.
Can find out, intelligent electric meter magnetic latching relay provided by the present invention is rational in infrastructure, easy to assembly, fail safe is high and cost is low.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below.Apparently, the accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the installation diagram of intelligent electric meter magnetic latching relay of the present invention;
Fig. 2 is the upper cover figure of intelligent electric meter magnetic latching relay of the present invention;
Fig. 3 is the electrical schematic diagram of intelligent electric meter magnetic latching relay of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, clear, complete description is carried out to the technical scheme in the embodiment of the present invention.Obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Be illustrated in figure 1 the installation diagram of intelligent electric meter magnetic latching relay.This intelligent electric meter magnetic latching relay comprises control red line 60, control black line 70, coil unit 10, moving plate unit 20 and still unit 30.Control the upside that red line 60 is arranged at drain pan 50.Control the upside that black line 70 is arranged at drain pan 50.Coil unit 10 is arranged at the top of described relay.Moving plate unit 20 is arranged at the bottom of described relay.Still unit 30 is arranged at the bottom of described relay.Moving plate unit 20 comprises copper-manganese sheet.
Control red line 60 and control black line 70 from drain pan 50 upper left side outlet, and not only can not realize quick for installation from upper casing outlet, easy disassembly, improves efficiency of assembling and assembly quality but also the safe distance added between forceful electric power and light current, improves security performance; Coil unit 10 belongs to weak current part, be placed on topmost, moving plate unit 20 and still unit 30 belong to strong power part, be placed on the bottom of relay, both achieved the isolation of light current and forceful electric power, enhanced security performance, can also make control section and strong power part completely isolated, because control line goes out the potential safety hazard brought in front end when avoiding the intelligent meter making to do isolation scheme, security performance is more stepped to a new level; Moving plate unit 20 and still unit 30 all use integral structure, the direct outlet from front end, whole relay is not only made to shorten distance to intelligent electric energy meter terminal direction, assemble more convenient, and shorten the length of moving plate unit 20 and still unit 30, decrease the use of copper material, reduce the cost of whole relay.
Be illustrated in figure 2 upper cover 80 figure of intelligent electric meter magnetic latching relay.This relay also comprises upper cover 80, and this upper cover 80 comprises multiple card base and snaps in drain pan 50.
Be illustrated in figure 3 the electrical schematic diagram of intelligent electric meter magnetic latching relay.This intelligent electric meter magnetic latching relay also comprises contact switch and gear unit 40, and this gear unit 40 controls described contact switch action by magnet.Be specially magnet by pulling described contact switch centered by fixing axis.
When control end (control red line 60 and control black line 70) adds the rated reverse voltage of coil, coil obtains electric, the A end of magnetic field suction gear unit 40 magnet that hot-wire coil produces is near coil, magnet rotates the moving plate action pulling contact switch centered by its fixing axis, moving plate unit 20 and still unit 30 are thrown off, thus contact switch is disconnected.When the voltage of certain pulse duration adds, continue after magnet action to add forward voltage and the magnetic direction produced due to hot-wire coil does not change and magnet can not continue action, therefore the driving voltage adding equidirectional in time afterwards is again nonsensical, even if thus disconnect the driving voltage on coil, switch also can keep the state after action.
On the contrary, if when control end adds the nominal forward voltage of coil, coil too electric, just the magnetic field of now hot-wire coil generation is contrary with direction when applying reverse energization voltage, attract the B end of gear unit 40 magnet near coil, magnet rotates the moving plate action promoting contact switch centered by its fixing axis, makes moving plate and still close, thus makes switch closed.When the voltage of certain pulse duration adds, continue after magnet action to add forward voltage and the magnetic direction produced due to hot-wire coil does not change and magnet can not continue action, therefore the driving voltage adding equidirectional in time afterwards is again nonsensical, even if thus disconnect the driving voltage on coil, switch also can keep the state after action.
Intelligent electric meter magnetic latching relay provided by the present invention is rational in infrastructure, easy to assembly, fail safe is high and cost is low.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the embodiment of the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from the spirit or scope of the embodiment of the present invention, can realize in other embodiments.Therefore, the embodiment of the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
These are only the preferred embodiment of the embodiment of the present invention; not in order to limit the embodiment of the present invention; within all spirit in the embodiment of the present invention and principle, any amendment done, equivalent replacement, improvement etc., within the protection range that all should be included in the embodiment of the present invention.
