Description
Technical Field
[0001] This application relates to the field of low-voltage electrical technology, and in particular to a contact module and a novel rotary disconnect switch. Background Technology
[0002] With the development of technology, especially in photovoltaic and wind power systems, photovoltaic DC switches are used in inverters to control the working status of multiple core components. The reliability of photovoltaic DC switches is not only related to the smooth operation of the entire photovoltaic system, but also to the stable development of the photovoltaic industry.
[0003] The most common photovoltaic DC switch in the prior art is the rotary disconnect switch. Its main structure includes an operating mechanism and a switch body. The switch body includes a moving contact, a stationary contact, and an arc extinguishing system. The rotation of the operating mechanism drives the moving contact and stationary contact in the switch body to connect and disconnect. When the moving contact and stationary contact disconnect, an electric arc is generated. The arc extinguishing system then processes these arcs to extinguish them. The switch body, as the main component responsible for disconnection, and the mounting and support of the moving and stationary contacts, is also a very important part of the entire switch system.
[0004] Regarding the aforementioned technologies, the switch body is a single layer that carries a set of moving and stationary contacts, which can control one circuit. However, in the main application system of this type of rotary disconnect switch, the inverter system, it is often necessary to control multiple circuits. This requires the switch to have multiple layers. Furthermore, due to the creepage distance requirements, the distance between the layers of the switch body is usually quite large. These factors combined result in the switch used in the inverter system occupying a considerable amount of space. Utility Model Content
[0005] To reduce the space occupancy of rotary disconnect switches in inverter systems, this application provides a contact module and a novel rotary disconnect switch.
[0006] The contact module and novel rotary disconnector provided in this application adopt the following technical solution: In one aspect, this application provides a contact module.
[0007] A contact module, comprising: A mounting housing having a mounting cavity is provided, and a rotating mounting disc is rotatably connected to the mounting housing. 2N arc-extinguishing chambers, wherein the arc-extinguishing chambers are connected to the mounting housing and are located within the mounting cavity; 2N stationary contacts are connected to the mounting housing. The stationary contacts and the arc-extinguishing chamber are alternately distributed around the circumference of the rotating mounting plate, and one end of each stationary contact extends into the mounting cavity. And N moving contacts, the moving contacts are embedded on the rotating mounting disk, and an insulating block is provided between two adjacent moving contacts. The rotating mounting disk rotates so that the two ends of the moving contacts abut against the two stationary contacts respectively. Where N is a positive integer and not less than 2.
[0008] By adopting the above technical solution, the designed contact module can serve as the mounting base for the rotating mounting plate, arc-extinguishing chamber, and stationary contact through the mounting shell. The rotating mounting plate can serve as the mounting base for the moving contact, driving the moving contact to rotate and thus achieve contact with the stationary contact, thereby enabling circuit conduction. The arc-extinguishing chamber can attract the generated arc during the process of the moving contact contacting and separating from the stationary contact. Furthermore, by optimizing the space design within the mounting cavity and the moving contact that can abut against the stationary contact at both ends, at least two sets of moving contacts and two sets of stationary contacts can be accommodated within the mounting shell. That is, under the same switching circuit requirements, about half of the space is saved, reducing the space occupancy rate of the rotary disconnect switch in the inverter system, thereby reducing the space design difficulty of the inverter system.
[0009] In one specific implementation, the moving contact includes: Two conductive sheets are provided, with protrusions formed on the side of each conductive sheet that is close to each other, and the two conductive sheets are stacked along the rotation axis of the rotating mounting disk. A pressing frame is formed with a receiving cavity for accommodating two layers of the conductive sheet. The pressing frame is connected to the conductive sheet and the protrusions on the two layers of the conductive sheet abut against each other to form a connection gap. The stationary contact can pass through and abut against the upper and lower sides of the connection gap.
[0010] By adopting the above technical solution, the designed moving contact can simultaneously contact the upper and lower sides of the stationary contact through the stacked two layers of conductive sheets, which increases the contact area with the stationary contact and improves the reliability of circuit conduction. The pressing frame can restrict the position of the conductive sheets and make the two layers of conductive sheets abut against each other.
[0011] In one specific implementation, at least 2N limiting plates are formed on the mounting housing, the arc extinguishing chamber is located in the limiting cavity formed by two adjacent limiting plates, and the limiting plates extend into the rotation radius of the moving contact to control the rotation angle of the moving contact.
[0012] By adopting the above technical solution, the designed limiting plates can be matched in pairs to form a limiting cavity, thereby realizing the control of the rotation angle of the moving contact and avoiding confusion in the contact relationship between the moving contact and the stationary contact.
[0013] In one specific implementation, the rotating mounting plate is connected to at least 4N partition plates, with an extension clearance between each pair of partition plates for one end of the moving contact to extend out, and the partition plates can cooperate with the limiting plates to separate two adjacent limiting cavities.
[0014] By adopting the above technical solution, the designed separator can cooperate with the limiting plate to separate two adjacent limiting cavities, thereby isolating the electric arc generated when the moving contact and stationary contact are separated in adjacent limiting cavities.
[0015] In one specific implementation, the arc-extinguishing chamber is disposed within the limiting cavity near the stationary contact.
[0016] By adopting the above technical solution, an arc-extinguishing chamber is designed to be located near the stationary contact within the limiting cavity, that is, the arc-extinguishing chamber is located near the initial segment of the separation path between the moving contact and the stationary contact, thereby attracting the electric arc generated when the moving contact and the stationary contact separate in a timely and effective manner.
[0017] In one specific implementation, the mounting housing includes an upper housing and a lower housing, which are detachably and fixedly connected. When the upper housing and the lower housing are fastened together, they form a mounting cavity. The stationary contact, the arc-extinguishing chamber, and the rotating mounting plate are all connected to the upper housing and the lower housing simultaneously.
[0018] By adopting the above technical solution, the designed mounting shell, which includes an upper shell and a lower shell, facilitates the installation of the stationary contact, arc-extinguishing chamber, and rotating mounting plate within the mounting cavity.
[0019] Secondly, this application provides a novel rotary disconnect switch.
[0020] A novel rotary disconnect switch includes: Drive the turntable; The contact module is connected to the extended end of the rotating mounting plate that extends out of the mounting cavity.
[0021] By adopting the above technical solution, the designed novel rotary disconnect switch can achieve rotation control of the rotating mounting plate inside the mounting housing through the drive disc. The mounting housing serves as the mounting base for the rotating mounting plate, the arc-extinguishing chamber, and the stationary contact. The rotating mounting plate serves as the mounting base for the moving contact, driving the moving contact to rotate and thus achieve contact with the stationary contact, thereby enabling circuit conduction. The arc-extinguishing chamber can attract the generated arc during the process of the moving contact contacting and separating from the stationary contact. Furthermore, by optimizing the space design within the mounting cavity and ensuring that the moving contact can abut against the stationary contact at both ends, at least two sets of moving contacts and two sets of stationary contacts can be accommodated within the mounting housing. That is, under the same switching circuit requirements, approximately half of the space is saved, reducing the space occupancy rate of the rotary disconnect switch in the inverter system, thereby reducing the spatial design difficulty of the inverter system.
[0022] In one specific implementation, there are multiple contact modules, which are arranged along the rotation axis of the drive turntable, and the rotating mounting disks in two adjacent contact modules are connected and their rotation axes coincide.
[0023] By adopting the above technical solution, a number of contact modules are designed, which can realize the rotation control of multiple rotating mounting plates at one time by driving the turntable.
[0024] In one specific implementation scheme, the drive turntable has at least one drive body protruding inward, and the extended end of the rotating mounting disk extending out of the mounting cavity has at least one arc-shaped groove for the drive body to extend into, and the arc degree corresponding to the arc-shaped groove is greater than the arc degree corresponding to the drive body.
[0025] By adopting the above technical solution, the arc groove designed with a corresponding arc angle greater than that of the drive body can make the rotation stroke of the drive turntable greater than that of the rotating mounting plate, that is, the rotation angle of the drive turntable is greater than that of the rotating mounting plate, thereby realizing the proportional relationship between the rotation angle of the drive turntable and the rotation angle of the moving contact, and thus adapting to the needs under various working conditions.
[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The designed contact module, through its mounting housing, can serve as the mounting base for the rotating mounting plate, arc-extinguishing chamber, and stationary contacts. The rotating mounting plate can serve as the mounting base for the moving contacts, driving them to rotate and thus make contact with the stationary contacts, thereby achieving circuit continuity. The arc-extinguishing chamber can attract the electric arc generated during the process of the moving contacts coming into contact with and separating from the stationary contacts. Furthermore, through optimized space design within the mounting cavity and moving contacts that can abut against the stationary contacts at both ends, at least two sets of moving contacts and two sets of stationary contacts can be accommodated within the mounting housing. This means that under the same switching circuit requirements, approximately half of the space is saved, reducing the space occupancy rate of the rotary disconnect switch in the inverter system and thus reducing the spatial design difficulty of the inverter system.
[0027] 2. The designed contact module can achieve simultaneous contact with the upper and lower sides of the stationary contact by stacking two layers of conductive sheets, which increases the contact area with the stationary contact and improves the reliability of circuit conduction. The pressing frame can restrict the position of the conductive sheets and make the two layers of conductive sheets abut against each other.
[0028] 3. The designed contact module, through the arc-extinguishing chamber located near the stationary contact within the limiting cavity, that is, the arc-extinguishing chamber is located near the initial segment of the separation path between the moving contact and the stationary contact, can timely and effectively attract the electric arc generated when the moving contact and the stationary contact separate.

[0036] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0037] This application discloses a contact module and a novel rotary isolating switch.
[0038] In a first aspect, embodiments of this application disclose a contact module.
[0039] Reference Figure 1 and Figure 2 A contact module includes a mounting housing 1, a rotating mounting plate 2, an arc-extinguishing chamber 3, a stationary contact 4, and a moving contact 5. The mounting housing 1 is hollow to form a mounting cavity. The rotating mounting plate 2 is rotatably connected to the mounting housing 1 and has an extension end extending out of the mounting cavity. The number of arc-extinguishing chambers 3 is 2N, and the arc-extinguishing chambers 3 are bolted to the mounting housing 1 and located inside the mounting cavity. The number of stationary contacts 4 is 2N, and the stationary contacts 4 are snap-fitted to the mounting housing 1. The stationary contacts 4 and the arc-extinguishing chambers 3 rotate around each other. The rotating mounting disk 2 has alternating circumferential distributions. One end of the stationary contact 4 extends into the mounting cavity to form a contact area. There are N moving contacts 5, which are embedded in the rotating mounting disk 2. At least one insulating block protrudes from the rotating mounting disk 2. The insulating block is placed between two adjacent moving contacts 5 to achieve insulation between two adjacent moving contacts 5. After the rotating mounting disk 2 rotates, the two ends of the moving contacts 5 abut against the contact areas of the two stationary contacts 4 respectively, thereby realizing circuit conduction. Here, N is a positive integer and N is not less than 2.
[0040] Reference Figure 1 and Figure 2In this application, N can be 2, 3, 4, or other positive integers, as long as it can be accommodated within the mounting cavity after satisfying various constraints such as creepage distance. In this embodiment, N is set to 2. The mounting housing 1 can serve as the mounting base for the rotating mounting plate 2, the arc-extinguishing chamber 3, and the stationary contact 4. The rotating mounting plate 2 can serve as the mounting base for the moving contact 5, and drive the moving contact 5 to rotate to achieve contact with the stationary contact 4 and thus achieve circuit conduction. The arc-extinguishing chamber 3 can attract the electric arc generated during the process of the moving contact 5 contacting and separating from the stationary contact 4. Furthermore, by optimizing the space design within the mounting cavity and the moving contact 5 that can abut against the stationary contact 4 at both ends, at least two sets of moving contacts 5 and two sets of stationary contacts 4 can be accommodated within the mounting housing 1. That is, under the same switching circuit requirements, about half of the space occupancy is saved, reducing the space occupancy rate of the rotary disconnect switch in the inverter system, thereby reducing the space design difficulty of the inverter system.
[0041] Reference Figure 1 and Figure 2 The mounting housing 1 includes an upper housing 11 and a lower housing 12, which are detachably and fixedly connected. In this application, the upper housing 11 and the lower housing 12 can be connected by snap-fit, bolt, or other means, as long as a detachable and fixed connection can be achieved. In this embodiment, the upper housing 11 and the lower housing 12 are bolted together; and after the upper housing 11 and the lower housing 12 are fastened together, they form a mounting cavity. The stationary contact 4, the arc-extinguishing chamber 3, and the rotating mounting plate 2 are all connected to the upper housing 11 and the lower housing 12 simultaneously.
[0042] Reference Figure 2 Specifically, the rotating mounting plate 2 includes an upper turntable and a lower turntable. There is a rotation gap between the upper turntable and the upper housing 11, and a rotation gap between the lower turntable and the lower housing 12. The upper and lower turntables are detachably fixedly connected by a snap fastener. The moving contact 5 is embedded in the lower turntable, and the position of the moving contact 5 is fixed after the upper and lower turntables are snapped together.
[0043] Reference Figure 3Specifically, the moving contact 5 includes a pressing frame 52 and two layers of conductive sheets 51. The two layers of conductive sheets 51 are stacked along the rotation axis of the rotating mounting disk 2, and multiple protrusions are integrally formed on the side of each conductive sheet 51 that is close to each other. After the two layers of conductive sheets 51 are stacked, the multiple protrusions of the upper and lower layers correspond to each other and maintain contact. The pressing frame 52 has a receiving cavity for accommodating the two layers of conductive sheets 51. The pressing frame 52 abuts against the conductive sheets 51, and the pressing frame 52 can make the protrusions on the two layers of conductive sheets 51 abut against each other. After the protrusions on the conductive sheet 51 abut against each other, a connection gap is formed at both ends of the conductive sheet 51. After the moving contact 5 rotates with the rotating mounting plate 2, the contact area of the stationary contact 4 can pass through the connection gap and abut against the upper and lower sides of the connection gap, thereby realizing circuit conduction. The two layers of conductive sheets 51 stacked together can simultaneously contact the upper and lower sides of the stationary contact 4, which increases the contact area with the stationary contact 4 and improves the reliability of circuit conduction. The pressing frame 52 can restrict the position of the conductive sheet 51 and make the two layers of conductive sheets 51 abut against each other.
[0044] Reference Figure 4 and Figure 5 Furthermore, at least 2N limiting plates 6 are integrally formed on the mounting housing 1. The arc extinguishing chamber 3 is located in the limiting cavity formed by two adjacent limiting plates 6, and the limiting plates 6 extend into the rotation radius of the moving contact 5. That is, when the moving contact 5 rotates, it will be blocked by the limiting plates 6, thereby controlling the rotation angle of the moving contact 5. They can cooperate in pairs to form a limiting cavity, thereby realizing the control of the rotation angle of the moving contact 5, thereby avoiding confusion in the contact relationship between the moving contact 5 and the stationary contact 4.
[0045] Reference Figure 4 and Figure 5 More specifically, at least 4N partition plates 7 are integrally connected on the rotating mounting plate 2. An extension clearance is formed between each two partition plates 7 for one end of the moving contact 5 to extend out. The partition plates 7 can cooperate with the limiting plates 6 to isolate two adjacent limiting cavities. Through the partition plates 7, the isolation between two adjacent limiting cavities can be achieved by cooperating with the limiting plates 6, thereby isolating the arc generated when the moving contact 5 and the stationary contact 4 are separated in adjacent limiting cavities.
[0046] Reference Figure 4 and Figure 5 Furthermore, the limiting cavity includes a contact area of a stationary contact 4, an arc-extinguishing chamber 3, and one end of a moving contact 5. The arc-extinguishing chamber 3 is located in the limiting cavity near the contact area of the stationary contact 4, that is, near the initial section of the separation path between the moving contact 5 and the stationary contact 4. By using the arc-extinguishing chamber 3 located in the limiting cavity near the stationary contact 4, that is, near the initial section of the separation path between the moving contact 5 and the stationary contact 4, the arc generated when the moving contact 5 and the stationary contact 4 separate can be attracted in a timely and effective manner.
[0047] The implementation principle of a contact module in this application embodiment is as follows: First, multiple stationary contacts 4 are embedded in the mounting position inside the lower housing 12. Then, the arc-extinguishing chamber 3 and the rotating mounting plate 2 are connected to the lower housing 12. Next, the moving contact 5 is embedded in the lower turntable. Then, the upper turntable and the lower turntable are fastened together to fix the position of the moving contact 5. Then, the upper housing 11 and the lower housing 12 are bolted together. At this time, the contact module is installed. Then, by applying force to the protruding end of the upper turntable that extends out of the mounting cavity, the rotation control of the moving contact 5 can be realized, thereby making the moving contact 5 contact or separate from the stationary contact 4, thus completing the circuit switching control.
[0048] Secondly, embodiments of this application disclose a novel rotary disconnect switch.
[0049] Reference Figure 6 A novel rotary disconnect switch includes a drive turntable 8 and a contact module as disclosed in the first aspect of the embodiments of this application. The drive turntable 8 is connected to the protruding end of the rotary mounting plate 2 extending out of the mounting cavity. The rotary mounting plate 2 can be driven to rotate by controlling the drive turntable 8. Further, a drive block 9 is rotatably mounted on the outer side of the drive turntable 8. At least one protrusion is formed on the drive turntable 8. At least one arc-shaped drive groove is formed on the drive block 9. The protrusion extends into the arc-shaped drive groove, and the arc of the protrusion is smaller than the arc of the arc-shaped drive groove. The rotation control of the rotary mounting plate 2 can be realized inside the mounting housing 1 through the drive turntable 8. The mounting housing 1 can serve as the rotary mounting plate 2 and the contact module of the contact module. The arc chamber 3 and the mounting base of the stationary contact 4 can be used as the mounting base of the moving contact 5 by rotating the mounting plate 2, and driving the moving contact 5 to rotate so as to make contact with the stationary contact 4 and thus realize the circuit conduction. The arc chamber 3 can attract the electric arc generated during the process of the moving contact 5 contacting and separating from the stationary contact 4. Furthermore, by optimizing the space design inside the mounting cavity and the moving contact 5 that can abut against the stationary contact 4 at both ends, at least two sets of moving contacts 5 and two sets of stationary contacts 4 can be accommodated in the mounting housing 1. That is, under the same switching circuit requirements, about half of the space is saved, reducing the space occupancy rate of the rotary disconnect switch in the inverter system, thereby reducing the space design difficulty of the inverter system.
[0050] Reference Figure 6 Furthermore, there are multiple contact modules, which are stacked along the rotation axis of the drive turntable 8. The rotating mounting disks 2 in two adjacent contact modules are inserted and connected, and the rotation axes of the rotating mounting disks 2 in two adjacent contact modules overlap and rotate synchronously.
[0051] Reference Figure 7Specifically, at least one driving body 81 is formed on the inner protrusion of the drive turntable 8, and at least one arc-shaped groove 21 is formed on the protruding end of the rotating mounting plate 2 extending out of the mounting cavity. The driving body 81 extends into the arc-shaped groove 21, and the arc degree corresponding to the arc-shaped groove 21 is greater than the arc degree corresponding to the driving body 81. Through the arc-shaped groove 21 with the arc degree corresponding to the arc degree corresponding to the driving body 81, the rotation stroke of the drive turntable 8 can be greater than the rotation stroke of the rotating mounting plate 2, that is, the rotation angle of the drive turntable 8 is greater than the rotation angle of the rotating mounting plate 2, thereby realizing the proportional relationship between the rotation angle of the drive turntable 8 and the rotation angle of the moving contact 5, and thus adapting to the needs under various working conditions.
[0052] The implementation principle of a novel rotary disconnector according to an embodiment of this application is as follows: First, multiple stationary contacts 4 are embedded into the mounting positions within the lower housing 12. Then, the arc-extinguishing chamber 3 and the rotary mounting plate 2 are connected to the lower housing 12. Next, the moving contact 5 is embedded into the lower rotating plate. Then, the upper rotating plate is fastened to the lower rotating plate to fix the position of the moving contact 5. Then, the upper housing 11 is bolted to the lower housing 12. At this point, the contact module installation is complete. Then, the driving block 9 applies force to the driving rotating plate 8, thereby causing the driving rotating plate 8 to rotate. Then, the driving rotating plate 8 extends to the upper rotating plate to the safety position. Applying force to the protruding end outside the cavity can achieve rotation control of the moving contact 5, thereby making the moving contact 5 contact or separate from the stationary contact 4, thus completing the circuit on / off control. Also, because the arc of the arc groove 21 is greater than the arc of the driving body 81, the rotation stroke of the driving turntable 8 is greater than the rotation stroke of the rotating mounting plate 2, that is, the rotation angle of the driving turntable 8 is greater than the rotation angle of the rotating mounting plate 2. This achieves the distribution of the proportional relationship between the rotation angle of the driving turntable 8 and the rotation angle of the moving contact 5, thus adapting to the needs of various working conditions.
[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
