Description
The present invention is the electrical equipment that a class will contain electromagnetic system, changes the device of silent power-saving DC operation into.
The electromagnetic system of electrical equipment such as existing A.C. contactor, electromagnet, automatic switch (coil, iron core and armature) exists that power consumption is many, temperature rise and shortcomings such as noise are arranged.In order to overcome these shortcomings, occurred as " quiet electricity economizer " of device parent company of China Electronics development and the products such as " direct current electricity-saving controllers " of Qingdao energy-conserving product development factory production.But, the suction rotating ring joint of these products must cooperate with the normally closed interlock of adapted contactor with external connection, coil afterflow controlling unit must match with stop button in external connection and the original control circuit etc., that is to say from space structure aspect circuit member to be dispersed on three devices, is not integral structure.So the wiring complexity installs trouble additional during use, especially at all can't wiring for the original control circuit of a lot of contactors.So, though, promote slowly so far at home through mandatory distribution.Simultaneously, electrical equipment such as widely used electromagnet and automatic switch in electromechanical equipment, because self does not have the normally closed interlock synchronous with armature movement, existing the said goods can not use.
It is incorporate to the purpose of this invention is to provide a class, and wiring is simply installed additional easily, in all have the scope of electromagnetic system electrical equipment, and the DC operation control device (quiet electricity economizer) that can both use.
Realize that basic scheme of the present invention is: as inhaling the rotating ring joint, make coil afterflow controlling unit (continuous control link) with the delay switch of special use etc., make incorporate DC operation control device with the switching circuit of special use.Described " integrated " is meant: inhaling the rotating ring joint does not need to cooperate with the normally closed interlock of matched with electric equipment with external connection, continuous control link does not need to use external connection to cooperate with former control circuit stop button, whole structure manufactures together, space structure aspect integrated.As shown in Figure 5, this control device is formed by inhaling rotating ring joint, continuous control link, step-down link and rectification circuit.Input terminal K
