Embodiment
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is further described.
Among this embodiment, the binding post design meets GB/Z XXXX-2007 " electric energy meter profile and installation dimension " technical standard, be provided with two unit of contact system and electromagnetic system in the three-phase magnetic latching relay housing, requirement according to three-phase electric energy meter, the contact system of different contacts load and the electromagnetic system of different power consumption can be set, it is little to have volume, contact load big (can reach 120A), characteristics such as reliable operation.
As shown in Figure 1, the utility model comprises binding post 1 and three-phase magnetic latching relay structure 2.Binding post 1 meets GB/Z XXXX-2007 " electric energy meter profile and installation dimension " technical standard.Three-phase magnetic latching relay structure 2 can be made the magnetic latching relay of different contacts load and different power consumption according to the three-phase kilowatt-hour meter specification requirement, and applicability is extensive.
The contact system of three-phase magnetic latching relay structure, three groups of contacts 3 are the bridge-type contact form, are arranged on the connecting rod 8, this connecting rod 8 is subjected to the moving part of electromagnetic system to drive and can move right, thereby makes three groups of contact 3 closures; When moving part to connecting rod 8 not during the application of force, contact spring 4 resets three groups of contacts 3; Slider material can be selected according to the load current size, and contact force is regulated by contact spring 4, can guarantee contact load big (maximum 120A), and the contact contact resistance is little, and temperature rise is low, reliable operation.
Shown in Fig. 2-4 three kinds of structural representations of three-phase magnetic latching relay contact system.Wherein magnetic latching relay contact 3 is all the bridging contact structure, and contact force can be regulated by selecting different contact spring 4.
Electromagnetic system has multiple version to select, and for example: suction-type magnetic circuit 5, its moving part are 91, as shown in Figure 2, is characterized in that armature stroke is big, and confining force is big;
Double armature is rotary 6, and its moving part is 92, as shown in Figure 3, is characterized in low in energy consumption, and volume is little;
Direct Action Type magnetic structure 7, its moving part are 93, as shown in Figure 4, are characterized in that volume is little, the transmission efficiency height.
The above-mentioned description to embodiment is can understand and use the utility model for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the utility model is not limited to the foregoing description, and those skilled in the art should be within protection range of the present utility model for improvement and modification that the utility model is made according to announcement of the present utility model.
