The effect covered prevents magnetic field from having an impact to DC relay inside, and the top of DC relay 1 is provided with arc chamber 5, electric arc
It is connected with inflating port 3 at the top of room 5 and positioned at the side of static contact 4, the bottom end of inflating port 3 extends to inside arc-chutes 13, inflation
The middle part of mouth 3 is equipped with air valve, and the hydrogen inside arc-chutes 13 can make arc extinguishing by opening air valve after long-time use
Hydrogen inside room 13 releases, and re-fill it is a certain amount of air valve is closed after the completion of inflation compared with pure hydrogen so that hydrogen
Replace more convenient, the middle part of arc chamber 5 is fixedly mounted there are two static contact 4, and the bottom of static contact 4 is equipped with arc-chutes 13, goes out
The outside of arc chamber 13 is fixedly installed with insulation grid 7, the middle part of shell 2 and is equipped with yoke 15, upper yoke 15 in the horizontal direction
Middle part be connected with connecting rod 9, the top of connecting rod 9 is fixedly installed with moving contact 8,9 middle part of connecting rod and is located under moving contact 8
Square set is equipped with coil rack 11 equipped with excess of stroke spring 14,2 inside of shell and the bottom for being located at upper yoke 15, coil rack 11
Outside is arranged with coil 12, and the bottom of upper yoke 15 is equipped with equipped with armature 10, the middle part of connecting rod 9 and the inner sleeve for being located at armature 10
Reaction spring 16, the outer sheath of armature 10 is equipped with self lubrication bearing 17, the outside of self lubrication bearing 17 and under armature 10
Side is equipped with sleeve 18, and the bottom of shell 2 is equipped with mounting seat 6, in use, by inflating port 3 to being filled with inside arc-chutes 13
Certain hydrogen then closes inflating port 3, adds certain voltage at the both ends of coil 12, at this time will inside coil 12
Certain electric current is flowed through, in 12 internal flow of coil galvanomagnetic-effect can occur for electric current, and armature 10 will be in the suction of electromagnetic force at this time
The pulling force of excess of stroke spring 14 is overcome to move upwards connecting rod 9 under the effect of drawing, thus the moving contact 8 and stationary contact that drive connecting rod 9 to make
First 4 are attracted, and after coil 12 powers off, the suction of electromagnetism also disappears therewith, and armature 10 can be in excess of stroke spring 14 and reaction spring 16
Reaction under return to original position, separate moving contact 8 with static contact 4.
The circulation for being attracted, discharging in this way, to achieve the purpose that conducting in circuit, cutting, with lesser electric current
Remove a kind of switch of control larger current, the effects of automatic adjustment, safeguard protection, conversion circuit can be played in circuit, electric current
It is easy to produce electric arc in closure and breaking course, such electric arc is since interelectrode medium is being initially that voltage is followed by electricity
The mixture mass pressed and generate the visible such as flame that ionization is formed under temperature action, it will cause short circuit, high current, high temperature, can
It can trip, burn electric appliance or catch fire, so the design of the arc-chutes 13 proposed, hydrogen is more difficult to ionize than air, so more can
Arc extinguishing, such arc-chutes 13 be it is closed, the inside does not have oxygen, even if there is a little oxygen, proportional band is also unlikely to burn, and
Hydrogen is non-conductive in sealed states, can reduce arc energy well using insulation grid 7 and arc-chutes 13, reduce to relay

Working principle: in use, by inflating port 3 to certain hydrogen is filled with inside arc-chutes 13, then by inflating port 3
It closes, adds certain voltage at the both ends of coil 12, will pass through certain electric current inside coil 12 at this time, electric current is in coil
Galvanomagnetic-effect can occur for 12 internal flows, and armature 10 will overcome the drawing of excess of stroke spring 14 under the sucking action of electromagnetic force at this time
Power moves upwards connecting rod 9, so that the moving contact 8 for driving connecting rod 9 to make and static contact 4 are attracted, after coil 12 powers off, electromagnetism
Suction also disappear therewith, armature 10 can original position is returned under the reaction of excess of stroke spring 14 and reaction spring 16, make
Moving contact 8 is separated with static contact 4, the circulation for being attracted, discharging in this way, thus achieved the purpose that conducting in circuit, cutting,
A kind of switch that control larger current is gone with lesser electric current, can play automatic adjustment, safeguard protection, conversion circuit in circuit
The effects of, electric current is easy to produce electric arc in closure and breaking course, and such electric arc is to be initially due to interelectrode medium
Voltage is followed by the mixture mass that the visible such as flame that ionization is formed is generated under voltage and temperature action, it will cause short-circuit, big
Electric current, high temperature may trip, burn electric appliance or catch fire, so the design of the arc-chutes 13 proposed, hydrogen are more difficult electricity than air
From, thus more can arc extinguishing, such arc-chutes 13 be it is closed, the inside does not have oxygen, even if there is a little oxygen, proportional band is also unlikely
In burning, and hydrogen is non-conductive in sealed states, can reduce arc energy well using insulation grid 7 and arc-chutes 13
Amount reduces the damage to 1 inside moving contact 8 and static contact 4 of DC relay, and can extend product well uses the longevity
Life.Hydrogen inside arc-chutes 13 can be such that the hydrogen inside arc-chutes 13 puts after long-time use by opening air valve
Out, and re-fill it is a certain amount of air valve is closed after the completion of inflation compared with pure hydrogen so that the replacement of hydrogen is more convenient, two
A through-hole is convenient for the installation of static contact 4, and dashpot can reduce impact force when moving contact 8 touches static contact 4.
