Description

Technical Field

[0001] The utility model relates to the field of bus ducts, in particular to a high-power density bus duct system. Background Art

[0002] High power density refers to the ability to provide a higher energy output rate per unit volume or mass. This feature enables equipment or systems to provide a large amount of electricity in a short period of time, and is particularly suitable for application scenarios that require rapid charging and discharging and high power output. Busbars are a closed metal device composed of copper and aluminum busbar columns, which are used to distribute large power to various components of a distributed system. Existing high-power busbars are distributed relatively densely, and busbars are usually assembled together in multiple sections. If a single busbar is damaged, it is usually necessary to monitor the busbar at the damaged location or the adjacent busbars for leakage before replacing the damaged busbar to avoid safety accidents. Since busbars are usually installed at high places, this makes detection and disassembly operations more complicated. Therefore, it is necessary to propose a high-power density busbar system to solve the above problems. Utility Model Content

[0005] The two busbar plug connectors are electrically connected to a same disconnect plate, on which a disconnect switch is rotatably mounted.

[0006] Preferably, a transparent neon gas tube is provided on the disconnect switch, a resistor is provided inside the disconnect switch, the bottom end of the resistor is connected to an elastic pen tip probe, the elastic pen tip probe is in active contact with the disconnect plate, a metal end cover is provided on the top of the disconnect switch, the transparent neon gas tube is provided between the resistor and the metal end cover, and the metal end cover is electrically connected to the transparent neon gas tube.

When connecting two bus ducts, the two connecting columns on the bottom guard plate at one end of the bus duct are inserted into the U-shaped clamping groove at the end of the other bus duct, so that the busbar plug connectors at the ends of the two bus ducts can be quickly and electrically connected together, with accurate positioning and stable connection;

[0012] 2. When disassembling or installing the damaged bus duct, it is easy to touch the bus duct in other positions, causing safety accidents. Therefore, you can hold the disconnect plate and rotate it to drive the disconnect switch to rotate, so that the disconnect switch and the contact position of the two busbar plug connectors are separated, so that the bus duct is de-energized and the nearby bus ducts are de-energized at the same time. This can avoid electric shock accidents and has high safety.

[0013] 3. When the operator presses his thumb on the metal end cover, a path is formed between the operator's body, the metal end cover, the transparent neon tube, the resistor, the elastic pen tip probe, the disconnect plate and the bus duct. At this time, if the bus duct is not powered off, the transparent neon tube will light up. If the power is off, it will not light up, allowing the operator to determine whether the bus duct is powered off, which can further improve safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] The utility model provides Figure 1-Figure 4 The high-power density busbar duct system shown includes a busbar duct body 1, and busbar plug connectors 2 are provided at both ends of the busbar duct body 1. The metal gaskets of the busbar plug connectors 2 at both ends are staggered to facilitate the connection between the busbar plug connectors 2. This technology belongs to the technology, so it will not be described in detail.

[0021] The U-shaped clipping grooves 5 are fixedly mounted on the sides of the two side guard plates 4 close to each other, and the two U-shaped clipping grooves 5 are symmetrically arranged with the busbar plug connector 2. A bottom guard plate 6 is fixedly mounted on the lower side of the busbar plug connector 2 at the other end of the busbar duct body 1. Connecting columns 7 are fixedly mounted on both sides of the upper surface of the bottom guard plate 6. The connecting columns 7 are matched with the U-shaped clipping grooves 5. When connecting two busbars, the two connecting columns 7 on the bottom guard plate 6 at one end of the busbar duct are inserted into the U-shaped clipping groove 5 at the other end of the busbar duct, so that the busbar plug connectors 2 at the two busbar duct ends are quickly and electrically connected together, with accurate positioning and stable connection.

[0022] Furthermore, the present invention electrically connects the two busbar connectors 2 with the same disconnect plate 8, and a disconnect switch 9 is rotatably installed on the disconnect plate 8. An insulating torque spring is provided on the rotating shaft at the bottom of the disconnect switch 9 and the disconnect plate 8, and the insulating torque spring is arranged in conjunction with the disconnect plate 8. During operation, if a single bus duct fails and needs maintenance, due to the relatively dense distribution density of the bus ducts, it is not safe to only detect whether the bus ducts at the damaged position or the adjacent position have leakage. When disassembling and assembling the bus duct at the damaged position, it is easy to touch the bus ducts at other positions, resulting in safety accidents. Therefore, the disconnect plate 8 can be rotated by hand to drive the disconnect switch 9 to rotate, so that the disconnect switch 9 is separated from the contact position of the two busbar connectors 2, so that the bus duct is de-energized, and the nearby bus ducts are de-energized at the same time, which can avoid electric shock accidents and has high safety.

[0023] Furthermore, the utility model is provided with a transparent neon gas tube 10 on the disconnect switch 9, a resistor 12 is provided inside the disconnect switch 9, the bottom end of the resistor 12 is connected to an elastic pen tip probe 11, the elastic pen tip probe 11 is in active contact with the disconnect plate 8, a metal end cap 13 is provided on the top of the disconnect switch 9, the transparent neon gas tube 10 is provided between the resistor 12 and the metal end cap 13, the metal end cap 13 is electrically connected to the transparent neon gas tube 10, when the power needs to be cut off for maintenance during work, the disconnect switch 9 is held by hand, the thumb is pressed on the metal end cap 13, and the elastic pen tip probe 11 is in active contact with the disconnect plate 8, and the metal end cap 13 is provided on the top of the disconnect switch 9. The transparent neon gas tube 10 is provided between the resistor 12 and the metal end cap 13, and the metal end cap 13 is electrically connected to the transparent neon gas tube 10. The elastic pen tip probe 11 can automatically extend and retract under the action of elasticity, so that the elastic pen tip probe 11 is always in contact with the disconnect plate 8. When the operator's thumb presses on the metal end cover 13, a passage is formed among the operator's body, the metal end cover 13, the transparent neon tube 10, the resistor 12, the elastic pen tip probe 11, the disconnect plate 8 and the bus duct. At this time, if the bus duct is not powered off, the transparent neon tube 10 will light up, and if the power is off, it will not light up, so that the operator can determine whether the bus duct is powered off, which can further improve safety.

[0024] The transparent neon tube 10 includes a transparent tube and a neon tube, and the neon tube is arranged inside the transparent tube. One end of the neon tube is electrically connected to the metal end cap 13, and the other end of the neon tube is electrically connected to the resistor 12. The setting of the transparent tube makes it easy to observe whether the neon tube is lit and can avoid leakage. This technology belongs to the existing technology and will not be described in detail.

[0025] Both side guard plates 4 are threaded with fixing bolts, and the two fixing bolts are movably connected to the connecting column 7. The setting of the fixing bolts can improve the stability of the bus duct connection. This setting is a conventional setting and will not be elaborated on.
