Description

Technical Field

[0001] This utility model relates to the field of composite switch technology, specifically a composite switch with a partition. Background Technology

[0002] In power systems, composite switches are widely used for controlling the switching operations of circuits, especially in high-voltage, high-current operating scenarios, where their performance directly affects the safety and stability of the circuit system. Existing composite switches typically employ a housing structure consisting of a top cover and a bottom shell connected together, with wiring holes at both ends for circuit connections. However, in practical use, the lack of effective isolation between the wiring holes makes them prone to arcing under high voltage / high current conditions, potentially leading to serious problems such as phase-to-phase short circuits. This significantly threatens the safe operation of the power system and reduces the reliability and lifespan of the composite switch.

[0003] To address the issues of arc isolation and phase-to-phase short circuit prevention, some composite switches incorporate partitions. However, these partitions are often fixed in place, making them difficult to adjust and replace flexibly according to different usage scenarios. When the operating environment or circuit parameters change, the fixed partitions cannot meet diverse needs, limiting the applicability of the composite switch and increasing equipment maintenance and replacement costs. Therefore, there is an urgent need for a composite switch structure that can effectively isolate arcs and prevent phase-to-phase short circuits while also flexibly adapting to different usage scenarios. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a composite switch with a partition.

[0005] The technical solution adopted by this utility model is as follows: a composite switch with a partition, comprising an outer shell formed by a top cover and a bottom shell connected together, wiring holes being provided at intervals at both ends of the outer shell, and a partition plate being provided. A sliding groove is provided on the outer shell between the wiring holes, and positioning protrusions are provided on the side walls of the sliding groove. A connecting part that slides and engages with the sliding groove is provided at one end of the partition plate. At least two or more positioning grooves are provided at equal intervals on both sides of the connecting part. The positioning protrusions and positioning grooves are interlocked. By pushing the partition plate to slide along the sliding groove, the positioning protrusions can be inserted into the positioning grooves or slide out of the positioning grooves.

[0006] Furthermore, the upper and lower sides of the positioning protrusion and the upper and lower sides of the positioning groove are all provided with a 30-40 degree slope.

[0007] Furthermore, the positioning groove is a "V" shaped groove or a trapezoidal groove, the shape of the positioning protrusion matches the positioning groove, and the gap between the two is less than 0.1mm.

[0008] Furthermore, the partition plate is made of epoxy resin-based composite material, and its surface is covered with a silicon nitride insulating coating, the surface of which has honeycomb grooves.

[0009] Furthermore, the groove is a "T" shaped structure or a wedge-shaped structure, and the connecting part matches the groove.

[0010] Furthermore, the thickness of the silicon nitride insulating coating is 0.1-0.3 mm.

[0011] Furthermore, the upper cover has multiple equally spaced "V"-shaped heat dissipation slots on both sides, and the opening area of ​​the heat dissipation slots accounts for 50%-70% of the surface area of ​​the upper cover side with the heat dissipation slots.

[0012] The beneficial effects of this utility model are:

[0013] Firstly, by setting a partition plate between the wiring holes, arcing can be effectively blocked in high voltage / high current scenarios, avoiding phase-to-phase short circuits. This greatly improves the safety and stability of the composite switch in complex power environments, ensures the reliable operation of the power system, and extends the service life of the composite switch.

[0014] Secondly, the partition plate and the sliding groove on the housing adopt a sliding fit, and the interlocking design of the positioning protrusion and positioning groove allows the partition plate to be flexibly adjusted and replaced according to the needs of the actual use scenario. When the use environment or circuit parameters change, the appropriate partition plate can be quickly and easily replaced without replacing the entire composite switch, significantly reducing the maintenance and replacement costs of the equipment and effectively improving the applicability and versatility of the composite switch.

[0015] Furthermore, the fitting structure of the positioning protrusion and the positioning groove not only facilitates the installation and disassembly of the partition plate, but also ensures that the partition plate remains stable during use, preventing displacement of the partition plate due to vibration and other factors, thus ensuring the continuous effectiveness of the arc isolation and short circuit protection functions, and further enhancing the reliability and practicality of the composite switch.

[0016] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0024] This utility model provides a composite switch with a partition.

[0025] In this embodiment, refer to Figure 1-5 The composite switch with partition includes an outer shell 3 formed by the upper cover 1 and the bottom shell 2. The outer shell 3 has wiring holes 4 spaced apart at both ends. It also includes a partition plate 5. A sliding groove 6 is provided on the outer shell between the wiring holes 4. Positioning protrusions 7 are provided on the side walls of the sliding groove 6. One end of the partition plate 5 is provided with a connecting part 8 that slides with the sliding groove. At least two positioning grooves 9 are provided at equal intervals on both sides of the connecting part 8. The positioning protrusions and positioning grooves 9 are interlocked. By pushing the partition plate 5 to slide along the sliding groove, the positioning protrusions can be inserted into the positioning grooves or slide out of the positioning grooves.

[0026] In the above technical solution, a sliding groove is provided on the housing of the composite switch. The partition plate slides in the groove through a connecting part, and the positioning protrusion and positioning groove are engaged to achieve the positioning and fixation of the partition plate on the housing. When it is necessary to adjust or replace the partition plate, the partition plate is pushed to slide the positioning protrusion out of the positioning groove, thus removing the partition plate from the sliding groove. After the partition plate is pushed to the appropriate position, the positioning protrusion re-embeds into the positioning groove, completing the new positioning and fixation. This design is based on the principle of mechanical sliding and engagement, ensuring that the partition plate is both stably installed and easily adjustable.

[0027] The partition plate can act as an arc-blocking device between the wiring holes, effectively preventing phase-to-phase short circuits. It is especially suitable for high-voltage / high-current scenarios, improving the safety of the composite switch. At the same time, the sliding fit and interlocking structure facilitates the replacement of the partition plate. The position of the partition plate can be adjusted or different specifications of partition plates can be replaced according to different application scenarios, improving the applicability and flexibility of the composite switch.

[0028] Specifically, the upper and lower sides of the positioning protrusion and the upper and lower sides of the positioning groove are provided with inclined surfaces 10 of 30-40 degrees.

[0029] In this embodiment, the inclined surface facilitates the sliding of the positioning protrusion out and in the positioning groove, making the installation and disassembly of the partition plate more convenient and smooth.

[0030] Specifically, the positioning groove is a "V" shaped groove or a trapezoidal groove, the shape of the positioning protrusion matches the positioning groove, and the gap between the two is less than 0.1mm.

[0031] In this embodiment, the closely matched positioning protrusion and positioning groove structure enables the partition plate to remain stable under vibration, external force and other conditions, preventing the partition plate from shifting; effectively ensuring the continuous effectiveness of arc blocking and short circuit prevention functions, and improving the reliability and stability of the composite switch in complex environments.

[0032] Specifically, the partition plate 5 is made of epoxy resin-based composite material, and its surface is covered with a silicon nitride insulating coating, the surface of which has honeycomb grooves 11.

[0033] In this embodiment, the separator is made of epoxy resin-based composite material, which has good insulation, mechanical strength, and corrosion resistance, meeting the basic performance requirements of the composite switch for the separator. The surface is covered with a silicon nitride insulating coating. Silicon nitride has excellent insulation and high-temperature resistance, further enhancing the insulation effect of the separator. The honeycomb groove design on the coating surface increases the contact area between the coating and air, utilizing the insulating properties of air to form multiple insulation barriers. Simultaneously, the honeycomb groove structure can disperse arc energy, reducing arc damage to the separator. This enhances the durability of the separator, extends the service life of the composite switch, and improves the safety and stability of equipment operation.

[0034] Specifically, the slide is a "T" shaped structure or a wedge shaped structure, and the connecting part matches the slide.

[0035] In this embodiment, the "T"-shaped or wedge-shaped groove and the matching connection part give the partition plate good stability after installation, making it less prone to shaking or displacement during use; at the same time, it ensures the smooth sliding of the partition plate, making it easy to adjust and replace it flexibly according to actual needs, thus improving the overall performance and ease of use of the composite switch.

[0036] Specifically, the thickness of the silicon nitride insulating coating is 0.1-0.3 mm.

[0037] In this embodiment, the thickness of the silicon nitride insulating coating is set to 0.1-0.3 mm. This thickness range has been optimized to ensure that the silicon nitride coating has sufficient insulation performance and protection capabilities, while avoiding affecting the overall size and installation compatibility of the partition plate due to excessive coating thickness.

[0038] Specifically, the upper cover has multiple equally spaced "V"-shaped heat dissipation slots 12 on both sides, and the opening area of ​​the heat dissipation slots accounts for 50%-70% of the surface area of ​​the upper cover side with the heat dissipation slots.

[0039] In this embodiment, the effective heat dissipation design can reduce the internal temperature of the composite switch, avoid the performance degradation or damage of components due to excessive temperature, and extend the service life of the composite switch; it also improves the stability and reliability of the composite switch under long-term continuous operation or high-load operation conditions, ensuring the normal operation of the power system.

[0040] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
