In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings that are required in the embodiments or the description of the prior art will be briefly described, it being obvious that the drawings in the following description are only some embodiments of the utility model, and that other drawings may be obtained according to these drawings without inventive effort for a person skilled in the art.
Fig. 1 is a schematic circuit diagram of the present utility model.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1, the utility model comprises a switch button AN, a control relay and a device load, wherein the control relay is a normally open and normally closed contact double-way relay, the switch button AN is sequentially connected with a normally closed contact K1 and a coil M in series at two ends of a control power supply, and a normally open contact K2 is connected in series on a power supply circuit of the load, wherein the opening and closing position of the normally open contact is AN arc generating position. The start and stop of this application through shift knob AN controlling means, and the electric arc can carry out the switching of frequency through the control of relay behind the opening device, and the frequency is the frequency of alternating current, non-critical data. At low frequencies, arcing is visible to the naked eye.
The control relay is characterized by further comprising a button indicator lamp, wherein the button indicator lamp is arranged between the normally closed contact point of the control relay and the coil in series and used for indicating the on-off condition of a circuit of the coil.
The power of the load equipment is not lower than 1000W. The intensity of the arc is related to the load current, the current is lower than 4A, the arc cannot be generated, the arc pulling distance is lower than 3 mm, the arc is not obvious, and the arc is not easy to observe.
The control relay is JZX-22 (D) 2Z. The relay is small in size and convenient to maintain, and the mounting seat is arranged.
The switch button AN is used for starting and stopping the arc generating device, is connected in series in the L live wire, one end of AN AC220V coil M of the control relay is connected with the live wire L through a normally closed contact K1, the other end of the AC220V coil M is directly connected with the zero line N, and a normally open contact K2 is connected in series on the live wire L of the load.
