Description

Technical Field

[0001] This utility model relates to an epoxy resin cast busbar, specifically a sealed, dustproof epoxy resin cast busbar. Background Technology

[0002] Epoxy resin cast busbar trunking is a new type of busbar trunking system that uses a mixture of high-performance epoxy resin and inorganic minerals to cast and seal copper busbars as a whole. The conductors are completely wrapped by epoxy resin, forming a seamless and dense insulation layer, which has extremely strong waterproof and dustproof capabilities.

[0003] Common epoxy resin cast busbars consist of a cast body and copper busbars. When connecting multiple busbar sections, the copper busbars on multiple sets of busbars need to be tightly connected. At the same time, to ensure insulation continuity, a secondary casting method is often used for connection. That is, after the copper busbars are tightly connected, epoxy resin is poured into the connection part to connect multiple busbar sections and form a continuous busbar.

[0004] The quality of on-site pouring is greatly affected by the environment (temperature, humidity, cleanliness) and the skill level of the operators. Problems such as bubbles, cracks, and poor adhesion to the busbars and outer casing are prone to occur, creating gaps where dust easily accumulates, leading to decreased insulation or creepage. Furthermore, the epoxy resin used in on-site pouring may age faster during long-term operation due to inaccurate proportions or incomplete curing, resulting in decreased insulation performance and becoming a potential point of failure. Additionally, once the epoxy resin cures at the connection points, it becomes integrated with the busbar trunking. If a section of the busbar trunking fails or additional lines are needed, the pouring head must be forcibly dismantled, a process that is extremely difficult and damages the original structure, making it very difficult to restore the initial sealing level. Utility Model Content

[0005] The purpose of this invention is to provide a sealed, dustproof epoxy resin cast busbar trunking to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sealed, dustproof epoxy resin cast busbar trunking includes a casting body; multiple sets of busbars are installed inside the casting body, and the multiple sets of busbars are equidistantly arranged.

[0008] It also includes multiple sets of connecting bases, which are respectively installed at both ends of the casting body;

[0009] Multiple sets of sealing plates are installed on the connecting base, and the cable tray is embedded in the sealing plate;

[0010] Connector, the connector being used to connect multiple sets of busbar trunking;

[0011] It also includes a locking element for increasing the connection strength of the connector.

[0012] The sealed, dustproof epoxy resin cast busbar as described above: the connector includes a connecting column mounted on the connecting base, and a mating wedge is installed on the connecting column; the sealing plate has a connecting groove, and the mating wedge and the connecting groove are slidably engaged.

[0013] The sealed dustproof epoxy resin casting busbar as described above: a fitting block is installed on the sealing plate on one side of the casting body; a fitting groove is opened on the sealing plate on the other side to engage with the fitting block.

[0014] The sealed, dustproof epoxy resin cast busbar as described above: the side of the sealing plate on which the interlocking block is installed is inclined away from the cast body.

[0015] The sealed dustproof epoxy resin cast busbar as described above: the locking component includes a locking wedge and a pressing wedge slidably installed in the sealing plate, wherein the locking wedge and the pressing wedge slide and press against each other, and a spring is provided in the sealing plate, the two ends of the spring respectively abutting against the pressing wedge and the sealing plate; the locking wedge and the pressing wedge press against each other.

[0016] The sealed dustproof epoxy resin cast busbar trunking described above: the sealing plate has a slot, and the locking wedge is equipped with a first wedge that slides into the slot.

[0017] The enclosed, dustproof epoxy resin cast busbar as described above: a protective outer shell is installed on the cast body.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] Employing a plug-in mechanical connection, the system achieves rapid and precise alignment through the sliding engagement of the connecting post, mating wedge, and connecting groove, followed by automatic locking by the locking mechanism. The entire process requires no special tools or waiting for materials to cure, significantly improving installation efficiency and ensuring stable and reliable connection quality. During docking, the sealing plate on one side embeds into the gap on the other side and deforms against each other, actively filling the connection gap and forming a sealed structure, greatly increasing the difficulty for dust to enter the busbar area. During docking, the connector positions multiple busbar troughs, preventing misalignment between busbars and reducing the contact area, thus improving the stability of power transmission. After docking, the locking mechanism increases the connection strength of the connector, making it more difficult for the busbar troughs to separate, thereby improving connection stability. The groove and first wedge design allow for easy release of the locking wedge using simple tools, easily separating the busbar troughs. This makes fault section replacement, line modification, or expansion very convenient and reduces maintenance costs. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0037] Please see Figures 1-7As an embodiment of the present utility model, the sealed dustproof epoxy resin cast busbar trunking includes a casting body 1; multiple sets of busbars 8 are installed inside the casting body 1, and the multiple sets of busbars 8 are equidistantly arranged.

[0038] It also includes multiple sets of connecting bases 2, which are respectively installed at both ends of the casting body 1;

[0039] Multiple sets of sealing plates 3 are installed on the connecting base 2, and the cable tray 8 is embedded in the sealing plate 3;

[0040] Connector, the connector being used to connect multiple sets of busbar trunking;

[0041] It also includes a locking element for increasing the connection strength of the connector.

[0042] In this embodiment, the casting body 1 is made of epoxy resin and is used to protect and isolate multiple sets of busbars 8.

[0043] The sealing plates 3 on both sides of the epoxy resin cast busbar are equally spaced and staggered. The spacing between the sealing plates 3 on the same side is slightly less than the thickness of the sealing plate 3, and the sealing plates 3 are made of epoxy resin and have a certain degree of elasticity.

[0044] When connecting multiple busbar trunking sets, one end of one busbar trunking is connected to the other end of another busbar trunking set. During the connection process, the sealing plate 3 on one busbar trunking set will enter the gap between multiple sealing plates 3 on another busbar trunking set, thereby causing the busbars 8 on multiple busbar trunking sets to come into contact with each other. At the same time, the sealing plates 3 are squeezed against each other and deformed to reduce the connection gap and prevent the busbars 8 from directly contacting the air, thereby preventing dust from accumulating on the busbars 8.

[0045] Furthermore, during the docking process, the connector is used for positioning when connecting multiple busbar trunkings, preventing misalignment between the busbars 8 and reducing the contact area, thereby improving the stability of power transmission.

[0046] After the connection is completed, locking components are used to increase the connection strength of the connectors, which increases the difficulty of separating the busbar trunking and thus improves the stability of the connection.

[0047] As a further embodiment of this utility model, the connector includes a connecting post 7 mounted on the connecting base 2, and a mating wedge 701 is mounted on the connecting post 7; a connecting groove 304 is provided on the sealing plate 3, and the mating wedge 701 and the connecting groove 304 are slidably engaged.

[0048] In this embodiment, before docking, the positions of the two busbar grooves are adjusted so that the mating wedge 701 is aligned with the connecting groove 304.

[0049] During the docking process, an external force is applied to bring the two busbar slots closer to each other, so that the mating wedge 701 is inserted into the connecting slot 304 (the mating wedge 701 and the connecting slot 304 slide and engage).

[0050] The contact action between the connecting groove 304 and the mating wedge 701 aligns multiple busbar slots, preventing misalignment and reducing contact knots between the busbars 8. This improves connection tightness and power transmission stability.

[0051] As a further embodiment of this utility model, a fitting block 301 is installed on the sealing plate 3 on one side of the casting body 1; and a fitting groove 302 is provided on the sealing plate 3 on the other side to engage with the fitting block 301.

[0052] In this embodiment, during the connection process, the wedge block 701 will first engage with the connecting groove 304. Through the mutual contact between the two, it can be ensured that the position of the busbar groove will not shift.

[0053] As the busbar troughs approach each other, the interlocking block 301 gradually approaches and inserts into the interlocking groove 302. Through the interlocking action of the interlocking groove 302 and the interlocking block 301, the bending resistance of the connection position between multiple sets of busbar troughs can be improved, avoiding bending and rotation during use, and increasing the stability of the connection between busbar troughs; it can also increase the airtightness of the connection part and increase the difficulty of the busbar 8 coming into direct contact with the air.

[0054] As a further embodiment of this utility model, the sealing plate 3 on which the fitting block 301 is installed is inclined on the side away from the casting body 1.

[0055] In this embodiment, since the gap between multiple sets of sealing plates 3 is slightly smaller than the thickness of the sealing plate 3, it will increase the difficulty for the sealing plate 3 on another busbar to enter the gap. Although it can greatly increase the airtightness of the connection position, it will increase the installation difficulty.

[0056] The sealing plate 3 with the interlocking block 301 installed has an inclined side away from the casting body 1, which makes it easier for the inclined surface of the sealing plate 3 to enter the gap during the connection process (due to the opening of the inclined surface, the thickness of the top of the sealing plate 3 is less than the width of the gap), which can effectively reduce the difficulty of the sealing plate 3 entering the gap and improve the installation efficiency.

[0057] As a further embodiment of this utility model, the locking member includes a locking wedge 4 and a pressing wedge 5 slidably installed in the sealing plate 3, wherein the locking wedge 4 and the pressing wedge 5 slide and press against each other, and a spring 6 is provided in the sealing plate 3, with the two ends of the spring 6 respectively abutting against the pressing wedge 5 and the sealing plate 3; the locking wedge 4 presses against the mating wedge 701.

[0058] In this embodiment, as the mating wedge 701 slides inward in the connecting groove 304, the mating wedge 701 will press against the locking wedge 4, thereby moving the locking wedge 4 away from the connecting groove 304; thus reducing the difficulty of inserting the mating wedge 701 into the connecting groove 304; the moving locking wedge 4 will press against the squeezing wedge 5, thereby moving the squeezing wedge 5 towards the spring 6, thus compressing the spring 6.

[0059] When the mating wedge 701 passes the locking wedge 4, the elastic force of the spring 6 will cause the pressing wedge 5 to move in the opposite direction, thereby pressing the locking wedge 4 and bringing it closer to the connecting groove 304. At this time, through the pressing action of the mating wedge 701 and the locking wedge 4 (the flat surface of the mating wedge 701 and the flat surface of the locking wedge 4 abut against each other), the difficulty of the mating wedge 701 moving outward in the connecting groove 304 can be increased, thereby increasing the stability of the busbar connection.

[0060] As a further embodiment of this utility model, the sealing plate 3 is provided with a groove 303, and the locking wedge 4 is provided with a first wedge 401 that slides and engages with the groove 303.

[0061] In this embodiment, when it is necessary to release the limiting effect of the locking member on the mating wedge 701, a tool (screwdriver, nail, etc.) can be used to move the first wedge 401 (for example, inserting the tool into the slot 303, the first wedge 401 can be slid in the slot 303 by the squeezing action of the tool); thereby making the locking wedge 4 move away from the connecting slot 304, so that the locking wedge 4 is separated from the mating wedge 701; then, by applying external force, the busbar trunking can be separated relatively easily; this can effectively reduce the difficulty of maintenance and replacement of the busbar trunking and improve work efficiency.

[0062] As a further embodiment of this invention, a protective outer shell 9 is installed on the casting body 1.

[0063] In this embodiment, the protective shell 9 can effectively improve the mechanical strength of the busbar trunking, thereby preventing wear and detachment of the epoxy resin casting 1 after long-term use, and ensuring the stability of power transmission and the service life of the busbar trunking.

[0064] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
