Limit plate 19 is installed, can be entered in moving contact loose slot 20 when moving contact 8 moves downward, moving contact 8 can avoid moving well
Abrasion of the contact 8 to upper yoke 15, limit plate 19 can limit moving contact 8, prevent from rotating out in 8 active procedure of moving contact
4 problem of static contact can not now be touched.
Further, insulate 7 inner roof wall of grid and be located at through-hole bottom be fixedly installed with static contact mounting rack 21, stationary contact
Head mounting rack 21 can limit static contact 4, and the loosening of static contact 4 can be avoided to cause connecing between moving contact 8 well
It touches bad.
Further, the top of arc chamber 5 and it is located between two static contacts 4 and is connected with shim, shim can be very well
Avoid DC relay 1 using time course static contact 4 by the corrosion of air so that service life improves well.
Further, the both ends of mounting seat 6 offer thread groove, thread groove be easily installed pedestal 6 and direct current after
The installation of electric appliance 1, so that DC relay 1 is easier for installation.
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.
In conclusion hydrogen of the utility model inside arc-chutes 13 can pass through opening after long-time use
Air valve releases the hydrogen inside arc-chutes 13, 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 through-holes are convenient for the installation of static contact 4, dashpot can reduce moving contact 8 touch it is quiet
Impact force when contact 4 can enter moving contact activity to avoid the loosening of static contact 4 well when moving contact 8 moves downward
In slot 20, moving contact 8 can avoid abrasion of the moving contact 8 to upper yoke 15 well, and limit plate 19 can limit moving contact 8
Position prevents rotation in 8 active procedure of moving contact from occurring that 4 problem of static contact can not be touched, and static contact mounting rack 21 can be to stationary contact
First 4 are limited, and the loosening of static contact 4 can be avoided to cause the poor contact between moving contact 8 well, and shim can be very well
Avoid DC relay 1 using time course static contact 4 by the corrosion of air so that service life improves well, screw thread
Slot is easily installed the installation of pedestal 6 and DC relay 1, so that DC relay 1 is easier for installation.
