Detailed Description
The embodiment of the utility model discloses electrified time delay combined floodgate's air switch, the combined floodgate through the electromagnetic mechanism time delay air switch who installs additional to the problem that will lean on the manpower combined floodgate among the solution prior art.
In order to make the technical field better understand the solution of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings and the detailed description. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the utility model provides an air switch of electrified time delay combined floodgate, including shell 1 and input 2, be provided with metallic conduction piece 3 in the input 2 be provided with electromagnetic mechanism 4 in the shell 1.
The utility model discloses install electromagnetic mechanism 4 additional in current air switch's inlet wire side, after inlet wire side joint pass band current, can close a floodgate with the air switch of separating brake in the time delay action after connecing the electricity, other conventional functions of air switch are unanimous with prior art.
Specifically, will electromagnetic mechanism 4 connects on metal conducting strip 3, electromagnetic mechanism 4 includes armature 5, iron core 6 and coil 7, coil 7 one end is connected at the input, and the closed circuit that the output end formed the intercommunication is connected to the other end, guarantees just to form the magnetic field in coil 7 and produce the heat on iron core 6 when the input is electrified.
