Description

Technical Field

[0001] The utility model relates to the field of auxiliary accessory equipment for box-type substations, and particularly to a new type of cable separation and anti-interference wire duct. Background Technique

[0002] The wire duct is a very important component of the low-voltage cabinet body of the box-type substation, which can facilitate wire routing and improve the aesthetics. There are many inter-cabinet wires in each group of cabinet bodies of the box substation, including primary wires and secondary wires. All wires need to be connected to other cabinet bodies through the wire duct. The existing solution is to directly lay the primary wires and secondary wires flat in the wire duct. Although this is simple in construction, can hide the wires, and improve the aesthetics of the cabinet body, directly contacting the primary cables with high voltage or large current with the secondary wires will cause some problems during later use and needs to be further improved.

[0003] At present, the main structural components of the wire duct include a wire duct body and a cover, which are detachably connected. It mainly has the following disadvantages: The primary and secondary wires are directly laid flat in the wire duct. The strong electrical signals of the primary wires will generate electromagnetic interference on the transmission of the weak electrical signals of the secondary circuit, which will cause signal disorders or malfunction, affecting the stability and reliability of the power system; The primary and secondary wires may be wound around each other in the wire duct, affecting later maintenance work, increasing the difficulty of identifying and locating problem points, and affecting work efficiency; The secondary wires are directly in contact with the primary wires with high voltage or large current and are easily damaged, increasing the risk of electric shock and endangering the safety of operators; The primary and secondary wires are wound together, and the internal wire routing is messy, which is not convenient for management and identification, increasing the difficulty of power system upgrade, expansion and change, and affecting later upgrade and transformation. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a new type of cable separation and anti-interference wire duct, with reasonable structural design, which can effectively avoid electromagnetic interference, improve the stability and reliability of the operation of the power system and the maintenance work efficiency, and make the wire laying more neat and orderly.

[0005] To achieve the above invention purpose, the technical solutions adopted by the utility model are as follows:

[0006] A new type of cable separation and anti-interference wire duct, which includes a wire duct body and a cover. The wire duct body and the cover are detachably connected. The wire duct body includes a duct box and insulating plates. The insulating plates are U-shaped, two in total, and are arranged on both sides of the duct box. The outer side of the insulating plate is in close contact with one side of the duct box, and the other side of the insulating plate is fixedly connected to the duct box through an L-shaped support. The U-shaped insulating plates form a secondary cable channel, and the gap space between the two insulating plates forms a primary cable channel.

[0007] Furthermore, the support is made of insulating material and is fixedly connected to the insulating plate or the duct box through nylon bolts.

[0008] The width of the primary cable channel is greater than that of the secondary cable channel.

[0009] The height of the insulating plate is less than or equal to the height of the cable trough.

[0010] Furthermore, the cable trough cover is made of insulating material, and the cable trough cover and the insulating plate can form an insulated cable channel, effectively avoiding electromagnetic interference between different cable channels.

[0011] Furthermore, six support members are required to be arranged for every 1000 mm long cable trough to fix the insulating plate, and three are arranged on each side of the cable trough.

[0012] The beneficial effects of the present utility model are as follows: The overall cable trough structure is reasonably designed. The cable trough is divided into three channels by the U-shaped insulating plate. The secondary wires are laid in the insulating channels on both sides, and the primary wires are laid in the middle channel, realizing the separate laying of primary and secondary cables, completely preventing the strong electrical signals of the primary wires from generating electromagnetic interference to the weak electrical signal transmission of the secondary circuit; at the same time, ensuring the stability and reliability of the power system operation, enhancing safety, being more convenient for maintenance and overhaul, making the cable laying neater and more orderly, and facilitating the upgrading and transformation of the power system in the later stage.

[0015] The present utility model will be described in detail below with reference to the drawings:

[0016] As shown in the attached Figure 1 A novel cable separation and anti-interference cable trough, which includes a cable trough body and a cable trough cover. The cable trough body and the cable trough cover are detachably connected. In this case, the cable trough body and the cable trough cover can be bolted. The cable trough body includes a cable trough 1 and an insulating plate 2. The cross-section of the cable trough 1 is a wide rectangular groove structure. The insulating plate 2 is U-shaped, with a total of two, arranged on both sides of the cable trough 1. The outer side of the insulating plate 2 is in close contact with one side of the cable trough 1, and the other side of the insulating plate is fixedly connected to the cable trough 1 through an L-shaped support member 3. The U-shaped insulating plate 2 itself forms a secondary cable channel 4, and the gap space between the two insulating plates 2 forms a primary cable channel 5.

[0017] Furthermore, the support member is made of insulating material and is fixedly connected to the insulating plate or the cable trough through nylon bolts, enhancing the strength and stability of the insulating plate.

[0018] The width of the primary cable channel is greater than that of the secondary cable channel.

[0019] The height of the insulating plate is less than or equal to the height of the trough box. After the insulating plate of this embodiment is fixed in the trough box, the upper edge of it is at the same height as the edge of the trough box. When the trough cover is fixed to the trough box, the upper edge of the insulating plate contacts the trough cover.

[0020] Furthermore, the trough cover is made of insulating material, and the trough cover and the insulating plate can form a complete insulating cable channel, effectively avoiding electromagnetic interference between different cable channels.

[0021] Furthermore, six support members are required to be arranged for every 1000 mm long wire trough to fix the insulating plate, and three are arranged on each side of the trough box.

[0022] The entire wire trough structure is reasonably designed. The trough box is divided into three channels by the U-shaped insulating plate. The secondary wires are laid in the insulating channels on both sides, and the primary wires are laid in the middle channel, realizing the separate laying of the primary and secondary cables, completely preventing the strong electrical signals of the primary conductors from generating electromagnetic interference on the weak electrical signal transmission of the secondary circuit; at the same time, ensuring the stability and reliability of the power system operation, enhancing the safety, being more convenient for maintenance and overhaul, making the cable laying more neat and orderly, and facilitating the later upgrade and transformation of the power system.
