Abstract
A contact point large space low-power consumption electromagnetic relay solves the question that the high power contact point large space relay must be used to control the high voltage electrical return circuit. The device includes a coil, an iron core, a movable armature, a support bracket, a spring, a limit piece, a connection terminal and a pedestal. The distance of an alloy contact point of the relay is enlarged, and a capacitance and a resistance are connected in parallel on a set of normally-closed contact of the relay. After an alternating current power is commutated utilizing a diode full bridge, the normally-closed contact, the capacitance and the resistance provide the pull-on momentary great current for the relay. After an alternating current power is commutated utilizing a diode, the resistance provides the pull-on hold mode low current for the relay operating coil. The utility model is mainly used to control circuit.

Background technology
At present, known general little gap, contact low-power relay can not be controlled the electric loop of high voltage, because relay contact is when disconnecting the electric loop of high voltage, relay contact will produce electric arc relay contact is burnt.The effective ways of eliminating relay contact electric arc are the gaps that increase between the contact, and the problem that increase brought in gap is between the contact, and the electric current that need significantly increase relay coil improves suction power, and it is a lot of that this just makes the power consumption of relay increase.Therefore, the big interval relay in the very big contact of power consumption will be used in the electric loop of control high voltage.
Summary of the invention
The utility model provides the big gap low-power consumption in a kind of contact electromagnetic relay, and its contact is big gap, and it inhales move instantaneous at coil is big electric current, be little electric current during the maintenance attracting state after the adhesive, so its power consumption is very little.It is on the basis of general relay mechanism, and the spacing of contact is widened, and forms with one group of normally-closed contact electric capacity in parallel and a resistance of relay.The operating current of relay coil is carried direct current by diode rectifier bridge, and instantaneous in the relay adhesive provides big electric current by normally-closed contact to inhaling moving winding at first, after normally-closed contact disconnects, provided by the charging current of electric capacity and the electric current of the resistance of flowing through.After the relay adhesive, the charging current of electric capacity is reduced to zero gradually, and at this moment only the flow through little electric current of resistance of the electric current of relay coil provides, so its power consumption is very low.It is to have utilized relay to need big electric current when adhesive, and the hold mode after the adhesive only needs very little principle to make.
The technical scheme that its technical problem that solves the utility model adopts is: on the basis of general relay mechanism, parts such as the coil of reservation relay, iron core, moving armature, support, spring, banking stop, binding post, base, the spacing of the alloy contact of relay is widened, at the one group of normally-closed contact shunt capacitance and the resistance of relay.With the diode full-bridge with the AC power rectification after, the adhesive transient high-current is provided for the relay energized coil through normally-closed contact, electric capacity and resistance.By the diode full-bridge with the AC power rectification after, the little electric current of adhesive hold mode is provided for the relay energized coil through resistance.Its one group normally-closed contact parallel connection the parallel circuits that forms of capacitor and resistor, one end of parallel circuits connects an end of the suction moving winding of relay, the other end of parallel circuits connects the output cathode of diode rectifier bridge, an end of inhaling moving winding connects the output negative pole of diode rectifier bridge, and the input of diode rectifier bridge connects power supply through switch.
The beneficial effects of the utility model are: this contact big gap low-power consumption electromagnetic relay has improved the off voltage of contact, reduced the power consumption of electromagnetic relay, a large amount of electric energy can have been saved in the electromagnetic relay long-term work, get caloric value when reducing electromagnetic relay work greatly, improved the reliability of work greatly.And it is simple in structure, and is cheap for manufacturing cost.
