Abstract
Description
Technical Field
[0001] This utility model relates to the field of relay technology, and more specifically, to a relay with an auxiliary low-voltage monitoring signal. Background Technology
[0002] With the development of new energy technologies such as photovoltaic energy storage, solar energy, and wind energy, the safety conditions for the use of power relays are becoming increasingly stringent, and the service life of the relays themselves is also being required to be higher. Therefore, it is necessary to propose a relay with auxiliary low-voltage monitoring signal.
[0003] Existing relays lack auxiliary contact monitoring and disconnection capabilities, resulting in low safety and reliability during use. This fails to meet customer and market demands, diminishes core competitiveness, and causes frequent contact misalignment, significantly increasing contact silver layer wear and contact adhesion risks. Consequently, the lifespan of relay products is reduced, failing to meet customer requirements.
[0004] Therefore, those skilled in the art have provided a relay with an auxiliary low-voltage monitoring signal to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to provide a relay with an auxiliary low-voltage monitoring signal, including a base, and further comprising:
[0006] A magnetic system is fixedly installed inside the base;
[0007] The main load circuit system is fixedly installed inside the base;
[0008] Auxiliary components are disposed inside the base.
[0009] As a further improvement to this technical solution, the magnetic system includes a yoke, an iron core, a frame, and a coil.
[0010] As a further improvement to this technical solution, the main load circuit system includes a movable piece, a stationary piece, an insulating piece, and contacts.
[0011] As a further improvement to this technical solution, the base has two assembly slots inside, and the auxiliary components include auxiliary moving springs and auxiliary stationary plates that are respectively fixedly installed inside the two assembly slots.
[0012] As a further improvement to this technical solution, the auxiliary moving spring is provided with an auxiliary moving contact inside, and the auxiliary stationary plate is provided with an auxiliary stationary contact inside.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] In this type of relay with auxiliary low-voltage monitoring signal, the auxiliary component simplifies the assembly process. First, the magnetic system and main load circuit system are assembled into the base. Then, the auxiliary component is fixedly installed into the base. When the relay is powered, the magnetic system's transition from electric to magnetic force activates the main load circuit, pushing the insulating sheet backward. This causes the insulating sheet to move the auxiliary moving spring synchronously, which in turn moves the auxiliary moving contact. When the auxiliary moving contact closes with the auxiliary stationary contact, the main load circuit is confirmed to be connected, and the signal feedback functions correctly. When the magnetic system is de-energized, the main load... When the circuit system is disconnected, the auxiliary moving contact will disconnect from the auxiliary stationary contact. However, when the magnetic system is de-energized, the main load circuit system remains connected, and the auxiliary moving contact will not disconnect from the auxiliary stationary contact either. This indicates that the main load circuit system has not disconnected properly, and the contacts inside the main load circuit system are stuck together. At this point, the auxiliary component will send a signal to forcibly cut off the current in the main load circuit system, thereby protecting the circuit from long-term or abnormal safety incidents that could lead to accidents. This device utilizes the breaking capacity of the auxiliary component to provide protection for the relay during operation, greatly improving the safety and reliability of the relay during use, better meeting customer and market demands, and enhancing the core competitiveness of the product.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1 - Figure 4 As shown, this embodiment provides a relay with an auxiliary low-voltage monitoring signal, including a base 1, and further including:
[0023] Magnetic system 2 is fixedly installed inside base 1;
[0024] The main load circuit system 3 is fixedly installed inside the base 1;
[0025] The auxiliary component is located inside the base 1.
[0026] The working principle described above is as follows: When assembling the relay as a whole, simply assemble the magnetic system 2 and the main load circuit system 3 into the base 1, and then fix the auxiliary components into the base 1. At this point, the relay can be assembled. When the relay is powered, the magnetic system 2, during the transition from electric to magnetic force, will cause the main load circuit system 3 to connect, pushing the insulating sheet 4 backward. The insulating sheet 4 will then drive the auxiliary moving spring 5 to move synchronously, which in turn drives the auxiliary moving contact 7 to move synchronously. When the auxiliary moving contact 7 and the auxiliary stationary contact 8 are closed, it can be confirmed that the main load circuit system 3 is connected, and the signal feedback can function normally. When the magnetic system 2 is de-energized, the main load circuit system 3 is disconnected. At this time, the auxiliary moving contact 7 will disconnect from the auxiliary stationary contact 8. When the magnetic system 2 is de-energized, the main load circuit system 3 is not disconnected. At this time, the auxiliary moving contact 7 and the auxiliary stationary contact 8 will not disconnect either, indicating that the main load circuit system 3 has not disconnected normally and the contacts inside the main load circuit system 3 are stuck together. At this time, the auxiliary component will feed back a signal to forcibly cut off the current of the main load circuit system 3, thereby protecting the circuit from long-term or abnormal safety incidents that could lead to safety accidents. This device utilizes the breaking capacity of the auxiliary component to enable the relay to have a protective function during operation, greatly improving the safety and reliability of the relay during use, better meeting customer and market needs, and enhancing the core competitiveness of the product.
[0027] In order for the relay to function properly, the magnetic system 2 includes a yoke, an iron core, a frame, and a coil. When the magnetic system 2 needs to be installed, the frame, coil, iron core, and yoke are first fixedly assembled. Then the magnetic system 2 can be assembled and fixedly installed on the base 1, so that the relay can be used normally.
[0028] Considering that the main load circuit system 3 also needs to be installed when using the relay, the main load circuit system 3 includes a movable piece, a stationary piece, an insulating piece 4, and contacts. When the main load circuit system 3 needs to be installed, simply fix the movable piece, the stationary piece, the insulating piece 4, and the contacts together. This completes the assembly of the main load circuit system 3. Then, fix the assembled main load circuit system 3 onto the base 1. At this point, both the magnetic system 2 and the main load circuit system 3 can be fixedly installed, allowing the relay to be used normally.
[0029] To enable the auxiliary moving contact 7 and the auxiliary stationary contact 8 to close and open, two mounting slots are provided inside the base 1. The auxiliary components include an auxiliary moving spring 5 and an auxiliary stationary plate 6, which are respectively fixedly installed inside the two mounting slots. When the relay is powered, the magnetic system 2 switches from electric to magnetic force, which connects the main load circuit system 3 and pushes the insulating plate 4 backward. At this time, the insulating plate 4 pushes the auxiliary moving spring 5 to move synchronously. The auxiliary moving spring 5 then drives the auxiliary moving contact 7 to move synchronously. When the auxiliary moving contact 7 and the auxiliary stationary contact 8 are closed, it can be confirmed that the main load circuit system 3 is connected and the signal feedback can work normally. When the magnetic system 2 is de-energized, the main load circuit system 3 is disconnected. At this time, the auxiliary moving spring 5 drives the auxiliary moving contact 7 to move synchronously, thereby disconnecting the auxiliary moving contact 7 and the auxiliary stationary contact 8. Through the setting of the auxiliary moving spring 5 and the auxiliary stationary plate 6, the closing and opening operations between the auxiliary moving contact 7 and the auxiliary stationary contact 8 can be effectively enabled.
[0030] In order to forcibly cut off the current of the main load circuit system 3, the auxiliary moving spring 5 is equipped with an auxiliary moving contact 7, and the auxiliary stationary plate 6 is equipped with an auxiliary stationary contact 8. When the relay is powered on, during the process of the magnetic system 2 switching from electric to magnetic force, the main load circuit system 3 is connected and the insulating plate 4 is pushed backward. At this time, the insulating plate 4 will push the auxiliary moving spring 5 to move synchronously. The auxiliary moving spring 5 will then drive the auxiliary moving contact 7 to move synchronously. When the auxiliary moving contact 7 and the auxiliary stationary contact 8 are closed, it can be confirmed that the main load circuit system 3 is connected and the signal feedback can work normally. When the magnetic system 2 is de-energized, the main load circuit system 3 is not disconnected, and the auxiliary moving contact 7 and the auxiliary stationary contact 8 are not disconnected. This indicates that the main load circuit system 3 has not been disconnected normally, and the contacts inside the main load circuit system 3 are stuck together. At this time, the auxiliary component will feed back a signal to forcibly cut off the current of the main load circuit system 3, thereby protecting the circuit, avoiding safety accidents, and effectively improving the overall safety of the relay.
