Problems solved by technology
However, the magnetic latching relays currently on the market often only have normally closed or normally open states.
In actual production, some production equipment has different working conditions, some working conditions require the relay to be in the normally closed state, and some working conditions require the relay to be in the normally open state. In this case, the conventional solution is to install two relays or Install a normally open contact and a normally closed contact in one relay. Installing multiple relays in the former not only takes up space, but two relays will also increase the complexity of the installed equipment structure and reduce reliability.
The latter increases the complexity of the magnetic control mechanism of the relay, which undoubtedly wastes more materials for the magnetic latching relay

The invention relates to the technical field of electromagnetic relays, in particular to a safe and stable magnetic latching relay and a voltage regulating device thereof. The relay comprise a shell, an on-off control mechanism, a switching mechanism and an electromagnetic control mechanism. According to the invention, the switching mechanism is designed, so that the relay can be switched between a normally open state and a normally closed state under the condition that only one group of electromagnets exist. An electromagnetic control mechanism is designed, a control center can stabilize voltage and current, and it is guaranteed that the electromagnet achieves the normal on-off function. When the electromagnetic control center receives the protection signal, the electromagnetic relay can be forced to be in an off state to protect the equipment. The on-off control mechanism of the device is provided with the arc extinguishing block, electric arcs generated during on-off of high voltage can be effectively reduced, the buffer block is provided with the static lead, static generated between the insulators can be guided to the shell, and static accumulation is prevented.
Description
technical field [0001] The invention relates to the technical field of electromagnetic relays, in particular to a safe and stable magnetic latching relay and a voltage regulating device thereof. Background technique [0002] The magnetic latching relay is a new type of relay developed in recent years, and it is also an automatic switch. Like other electromagnetic relays, it can automatically switch on and off the circuit. The difference is that the normally closed or normally open state of the magnetic latching relay is completely dependent on the effect of the permanent magnet, and the switching state of the relay is triggered by a pulse electric signal of a certain width. However, the magnetic latching relays currently on the market often only have a normally closed or normally open state. In actual production, some production equipment has different working conditions, some working conditions require the relay to be in the normally closed state, and some working conditi...
