Abstract
The utility model relates to a three-phase electromagnetic relay, which consists of a base, a heel piece, electromagnetic coils, a tension spring, a gag bit, an insulation bracket, an upper static contact head contact sheet assembly, a lower static contact head contact sheet assembly and a movable contact sheet spring sheet assembly. The utility model is characterized in that the two sides of the center of the base are provided with two electromagnetic coils which are serially connected; an insulation contact head seat is arranged before the base and an insulation connection seat is arranged behind the base; three arc extinguish chambers which are internally embedded with arc extinguish grating sheets are arranged on the insulation contact head seat. As a sensing mechanism and an executing mechanism of the relay are arranged at the upper plane of the base, the height is low and the volume is small. The arranging of the arch extinguish device can prevent over-flash produced in big current work and impacting current caused by the over-flash, prolonging the mechanical life of the electric contact head. The utility model can replace the alternating current contactor with the same current grade; furthermore, the utility model overcomes the complicated structure of the alternating current contactor of only operating inverse and smooth conversion, so as to simplify the electric device and the volume of the switch cabinet.
Description
The utility model relates to a kind of electromagnetic relay, refers in particular to a kind of three-phase electromagnetic relay.
Electromagnetic relay is a kind of automatic electrical equipment, is widely used in the control of motor or route protection and Automation of Manufacturing Process.Its basic structure includes two parts: sense mechanism and actuator.Sense mechanism is the electromagnetic system of being made up of armature, iron core and coil often, and it can reflect the variation of relay input variable.Actuator is the contact system of being made up of dynamic and static contact and annex often, and it constitutes the output of relay.Chinese patent once disclosed a kind of " high-power magnetic relay " (ZL87200024, stop), form by pedestal, yoke, solenoid, extension spring, armature, insulator support, upper static contact contact sub-assembly, following fixed contact contact sub-assembly, movable contact spring spring combination spare, be characterized in four groups of contacts and arc extinguishing barrier.But its structural configuration is unreasonable, and volume is big, and function is few, is difficult to replace A.C. contactor.
Task of the present utility model is to provide a kind of three-phase electromagnetic relay, and it can replace A.C. contactor, and easy-to-connect, installs simply, and highly sensitive, breaking capacity is strong.
For finishing above-mentioned task, the solution that the utility model is taked is: a kind of three-phase electromagnetic relay, form by pedestal, yoke, solenoid, extension spring, armature, insulator support, upper static contact contact sub-assembly, following fixed contact contact sub-assembly, movable contact spring spring combination spare, two solenoids are equipped with on both sides in the middle of it is characterized in that pedestal, two solenoid series connection, the pre-installed insulation contact seat of pedestal, back dress insulation joint seat, three arc control device are arranged on the insulation contact seat, be embedded with arc extinguishing grid pieces in the arc control device.
Because it is the sense mechanism and the actuator of floor plan relay on the pedestal of the present utility model, therefore highly low, volume is little.Owing to be provided with arc-control device (arc control device and arc extinguishing grid pieces), arcing that produces when preventing big current work and the impulse current that causes have thus prolonged mechanical endurance of electrical contact.The utility model can replace the A.C. contactor with current class, and the A.C. contactor list is only operated down, clockwise complexity structure of changing but overcome, and has therefore simplified electric device and switch cubicle volume.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
