Description
Technical field
The utility model relates to a kind of electronics, electric equipment safety guard, especially a kind of release that is used on the electric arc fault protection device.
Background technology
Along with the raising of rapid development of economy and people's lives, power consumption is also in continuous increase.Electrical Safety comprises the fire that personal safety and preventing is leaked electricity or arc fault causes, is subjected to people day by day and payes attention to.The fire that arc fault causes accounts for more than 60% in all electrical fires, so people improve gradually to the attention degree of low-voltage electrical safety and electric arc fault protection.
Electric arc is the continuous discharge phenomenon of crossing over certain dielectric between two electrodes, often is accompanied by the part volatilization of electrode.Typical electric arc is to form in the airspace between yin, yang the two poles of the earth.Arc center's temperature is generally 5000 to 15000 degrees centigrade.The zone that electric arc exists can produce very high ionization air pressure, and what cause that electric arc limited to all can discharge hot gas and electrode substance particle Anywhere.
Electric arc on the circuit can be divided into two kinds, and a kind of is normal operation arc, claims " good arc " that another kind is a fault electric arc, claims " bad arc "." good arc " is meant the arc that motor rotation (as electric drill, dust catcher etc.) produces.When people's device for switching, the arc that produces during plug electrical equipment also belongs to " good arc " in addition." bad arc " is fault electric arc, and fault electric arc generally results from two kinds of situations: 1. along insulator part conductive surface; 2. result from 2 very approaching electrodes.The former causes the insulating surface carbonization and forms arc channel because insulator is heated for a long time or the contingency electric spark takes place; The latter is because electric conductor is run into ground conduit, or part is hurt insulation by sharp-pointed metallic object in a branch of conductor.In the low pressure power and distribution supply cable, series arc faults, Line To Line arc fault and line arc fault is over the ground arranged.
The series connection fault generally results from 1 conductor, has 1 mechanical breaking takes place in for example a branch of conductor, or unclamps at the conductor tab place, or have a utmost point to disconnect at the plug place.The electric current of series connection fault is subjected to the restriction of load, thereby electric current may be less than load current; Line-to-line fault is a kind of short circuit, for example 2 conductor insulation surface mechanical damages in a branch of conductor is collided, and this arc current is decided by the size of line impedance; Line betides the situation of grounded circuit to earth fault.
The utility model content
The purpose of this utility model provide a kind of can be according to signal to cutting off the release on the electric arc fault protection device of being used in of circuit.
Realize the release on the electric arc fault protection device of being used in of the utility model purpose; comprise: base 1; this base 1 is provided with iron core 7 and support bar 13; the described unshakable in one's determination 7 outer solenoids 9 that are tied with; be fixed with supporting bracket 14 on the described support bar 13; described supporting bracket 14 is provided with pinching screw 3 and is enclosed within on the described pinching screw 3; spring 2 between 3 one of pinching screws and described supporting bracket 14; described pinching screw 3 is provided with the arm-tie 15 that is positioned at supporting bracket 14 tops; described arm-tie 15 is connected with a plate button 11; the support bar 13 of described plate button 11 tops is provided with adjusts screw 4; described plate button 11 other ends are fixed with pull bar 12; described pull bar 12 is provided with contact 10; described plate button 11 belows are fixed with armature 6; the below of armature 6 is provided with non magnetic pad 5, and described plate button 11 can be followed arm-tie 15 and drive pull bar 12 perks under the effect of spring 2.
Described pull bar 12 passes in the middle of two locating pieces 16 that are fixed on the base 1, and described plate button 11 other ends are used for the location of plate button 11 between described two locating pieces 16.
Description of drawings
Fig. 1 is used in the structural representation of the release on the electric arc fault protection device for the utility model.
Embodiment
As shown in Figure 1; the release that is used on the electric arc fault protection device of the present utility model; comprise: base 1; this base 1 is provided with iron core 7 and support bar 13; the described unshakable in one's determination 7 outer solenoids 9 that are tied with; be fixed with supporting bracket 14 on the described support bar 13; described supporting bracket 14 is provided with pinching screw 3 and is enclosed within on the described pinching screw 3; spring 2 between 3 one of pinching screws and described supporting bracket 14; described pinching screw 3 is provided with the arm-tie 15 that is positioned at supporting bracket 14 tops; described arm-tie 15 is connected with a plate button 11; the support bar 13 of described plate button 11 tops is provided with adjusts screw 4; described plate button 11 other ends are fixed with pull bar 12; described pull bar 12 is provided with contact 10, and the described plate side of detaining is fixed with armature 6, and the below of armature 6 is provided with non magnetic pad 5; described plate button 11 can be followed arm-tie 15 and drive pull bar 12 perks under the effect of spring 2.Described pull bar 12 passes in the middle of two locating pieces 16 that are fixed on the base 1, and described plate button 11 other ends are used for the location of plate button 11 between described two locating pieces 16.
When fault-free takes place; the microprocessor of electric arc fault protection device does not send trip signal to release, so solenoid 9 no currents of release, the armature 6 of release is held by the suction that Φ 1 in unshakable in one's determination 7 the magnetic flux is produced; spring 2 is tightened up, and release is in closure state.
When breaking down, there is electromotive force to be added on the solenoid 9 of release, makes in the solenoid 9 and flow through alternating current, thereby produce alternating flux Φ 3, opposite with unshakable in one's determination 7 magnetic flux Φ 1 directions that produce, cancel each other, the electromagnetic attraction of release is reduced, when the electric current on being added to solenoid 9 reaches certain value, release armature 6 discharges under spring 2 effects, snap close on the armature 6 is thrown off, and makes 11 actions of plate button, and the contact 10 of release disconnects main circuit.
Person skilled in the art should be familiar with, the above embodiment is used for illustrating the purpose of this utility model, and be not with opposing qualification of the present utility model, as long as in essential scope of the present utility model, variation, modification that the foregoing description is done all will drop in the claim scope of the present utility model.
