Characteristics of Electron Beam Welding of Manganese Copper Shunts of Magnetic Latching Relays
1) The energy density of electron beam welding is high, and it can weld welds that are difficult to achieve by ordinary arc welding;
2) Electron beam welding is carried out in vacuum, the chemical composition of the weld is stable and pure, the joint strength is high, and the weld quality is high;
3) The electron beam welding speed is fast, the heat affected zone is small, and the welding thermal deformation is small;
4) Electron beam welding is suitable for welding almost all metal materials, especially for Copper Alloy Shunt and aluminum welding;
5) Electron beam welding can obtain welds with a large aspect ratio (20: 1 ~ 50: 1), and when welding thick parts, it can be formed at one time without opening the groove;
6) Electron beam welding combines computer technology to achieve precise control of process parameters and fully automate the welding process.
Electron beam welding technology is currently the fastest growing and most widely used electron beam technology.
The structure of the Magnetic Latching Relay
The magnetic latching relay is divided into two layers, the upper layer is the electromagnetic system, and the lower layer is the Silver Electric Contact system. The electromagnetic system adopts a flat direct-acting magnetic latching magnetic circuit system, which includes a Terminal Block Manganin Shunt, a coil, an Electrician pure iron armature, an Electrician pure iron core, and a mounting plate. The Prepayment Meter Shunts are located on the mounting plate. In the center, coils are installed on both sides of the Cable Wire Shunt Resistor, a U-shaped iron core is arranged above the coil, and the armature is positioned between the iron cores to form an annular structure, which can be controlled by a Primary Wire Manganin Shunt field. Both ends of the mounting plate are located beside the U-shaped bottom of the iron core, and a pure iron plate is also installed to prevent the interference of external Braze Welding Shunt Resistance fields (for Energy Meter ).
Application Notes for Magnetic Latching Relays
1. The factory state of the holding relay is usually the Electrical Silver Contact closed state, but the state may be changed due to factors such as impact during transportation or installation of the relay. Therefore, it is necessary to take measures to reset the Bimetal Electronic Contacts before use.
2. In order to make the magnetic latching relay operate reliably, the voltage applied to the coil must reach the rated voltage value, and the pulse width must reach more than 3 times the operating time.
3. The magnetic latching relay coil is polarized, and the customer must specify the coil polarity when ordering, so that I can produce it.
4. The shape and installation size of the holding relay cannot be changed in general. Customers should pay attention to whether the shape and size of the relay meet the requirements when selecting models. The peripheral accessories of the magnetic latching relay can be customized according to customer requirements. For double hard-connected products, there must be one side of the lead-out conductive sheet that is relatively flexible; if both sides are rigid, it is easy to generate large stress after the relay is installed, which may change the parameters of the relay.
5.The Manganin Shunt Latching Relay should be handled with care when entering the factory for inspection and installation to prevent falling to affect the parameters; products for destructive testing should be strictly distinguished from normal products and should not be used.
