Abstract
The invention relates to a sparkles relay which eliminates electric sparks generated by an on-off action of a relay. The sparkles relay adopts the technical scheme that a potentiometer is connected in series between two electrodes of the relay, and the change of the resistance value of the relay from the minimum to the maximum and from the maximum to the minimum finishes the on-off action of the relay, thus discharge sparks caused by the on-off action of the relay are greatly weakened and even eliminated so as to ensure that the electrical endurance of a heavy-current relay is greatly prolonged, and electromagnetic interference cannot be generated by the on-off action of the heavy-current relay.
Description
Affiliated technical field
The invention belongs to relay and make technical field, relate to the contact spark technology for eliminating.
Background technology
Relay is of a great variety, all can produce electric spark when the relay contact of all kinds opens and closes at present, and surrounding environment is caused electromagnetic interference, and relay contact is caused calcination and damage, has a strong impact on the electrical endurance of relay.High-current relay is especially true, the high-current relay electrical endurance of a lot of occasions not and one of the percentage of mechanical endurance, so high-current relay often adopts various arc extinguishing technology, causes that the high-current relay volume is big, cost is high.
Summary of the invention
Purpose of the present invention: the electric spark that produces when eliminating the relay switch action.
Technical scheme provided by the present invention is: the switch that makes relay is from the short circuit of opening a way, have a progressive formation from being shorted to open circuit, and not sudden change.This potentiometer of can between two electrodes of relay switch, connecting, the resistance of potentiometer is from being up to minimum, and the switch motion of relay is finished in the variation from the minimum to the maximum again.In fact in order to finish better switch performance, tandem tap potentiometer between two electrodes of relay switch, when relay needs switch closure like this, the switch closure of potentiometer with switch before this, then potentiometer resistance rapidly from be up to minimum, to short circuit, when relay needs switch to disconnect, potentiometer resistance rapidly from be shorted to minimum, to maximum, then the switch of potentiometer with switch disconnects.
Beneficial effect of the present invention: weaken greatly even eliminate the discharge spark that relay switch causes, the electrical endurance of high-current relay is extended greatly, no longer produce electromagnetic interference when making the high-current relay switch motion.Do not had electric spark, also just do not needed arc-control device, will make the high-current relay volume-diminished, cost reduces.
Embodiment
An electrode series connection slide switch potentiometer of relay switch, another electrode connects the centre cap of slide switch potentiometer, and the actuating unit of relay drives the slide bar action of slide switch potentiometer, finishes the switch of relay electrode.Should assemble the slide switch potentiometer of different capacity according to the difference of relay current.
Claims (4)
1, Sparkles relay, the switch that makes relay exactly are from the short circuit of opening a way, have a progressive formation from being shorted to open circuit, and not sudden change is characterized in that: potentiometer of series connection between two electrodes of relay switch.
2, according to claim 1 described Sparkles relay, in order to finish better switch performance, its further feature is: tandem tap potentiometer between two electrodes of relay switch.
3, according to claim 1 described Sparkles relay, its further feature is: the resistance of potentiometer is from being up to minimum, and the switch motion of relay is finished in the variation from the minimum to the maximum again.
4, according to claim 2 described Sparkles relays, its further feature is: when relay needs switch closure, the switch closure of potentiometer with switch before this, then potentiometer resistance rapidly from be up to minimum, to short circuit, when relay needs switch to disconnect, potentiometer resistance rapidly from be shorted to minimum, to maximum, then the switch of potentiometer with switch disconnects.
