Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, and more particularly to a cast bus duct. Background Art

[0002] Cast bus duct is a type of power transmission equipment in which the busbar is tightly wrapped with insulating resin or composite materials through casting. This structure not only provides excellent electrical insulation performance, but also greatly enhances the mechanical strength and environmental resistance of the bus duct. Cast bus duct usually consists of conductive copper or aluminum busbars, insulation layer, casing and necessary connection and fixing parts. The insulation layer is made of high-performance insulating resin or composite material. It is tightly combined with the busbar through the casting process to form a solid electrical barrier, effectively preventing current leakage and short circuit. Bus duct is widely used in high-rise buildings, industrial plants, commercial centers, large public facilities and other occasions, especially in those places where large current transmission is required and there are many branch circuits.

[0003] Disadvantages of existing cast-type bus duct:

[0004] First, the existing bus duct has two end flanges at the bottom, which are mainly connected to the cables. However, the cables are very hard, and the hard cables will deform the end flanges during installation, resulting in a reduction in the safe distance between the end flanges, which is very unsafe.

[0005] Second, the existing bus duct is placed outdoors. When it rains, a small amount of water will accumulate on the surface of the bus duct. The interior of the bus duct is very sensitive to moisture. Once moisture enters the bus duct, it will reduce the insulation performance of the insulation material and increase the risk of short circuit and leakage. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cast bus duct to solve the problems existing in the above-mentioned background technology.

[0007] The utility model provides the following technical solution: a cast-type bus duct, comprising a bus duct body, mounting blocks fixedly connected to both sides of the bus duct body, a starting flange head fixedly connected to the front of the mounting block, an insulating support movably connected inside the starting flange head, an external thread opened on one side of the outer surface of the insulating support, a rotating cover movably connected to the outer surface of the external thread, a scraper block movably connected to the top of the bus duct body, and a threaded rod movably connected to the inner surface of the scraper block;

[0008] Furthermore, reinforcing ribs are fixedly connected on both sides of the bottom of the bus duct body, fireproof cotton is fixedly connected to the inner surface of the bus duct body, and limiting reinforcement strips are fixedly connected on both sides of the top of the bus duct body, and a water outlet is opened in the middle of the limiting reinforcement strip.

[0009] Furthermore, a mounting block is fixedly connected to the back of the starting flange head, a wiring hole is provided at the front end of the starting flange head, a through hole is provided at the rear end of the starting flange head, and a first mounting hole is provided on one side of the starting flange head.

[0010] Furthermore, the inner surface of the through hole is movably connected to an insulating support, one side of the insulating support is fixedly connected to a disc, one side of the disc is provided with a second mounting hole, one side of the second mounting hole is provided with a first mounting hole, and the inner surfaces of the first mounting hole and the second mounting hole are movably connected with a fixing bolt.

[0011] Furthermore, both sides of the scraper block are movably connected with limit reinforcement strips, both sides of the front of the scraper block are provided with water diversion grooves, the inner surface of the scraper block is connected with a threaded rod, and the back of the threaded rod is fixedly connected with a motor.

[0012] Furthermore, a threaded hole is provided on the inner surface of the scraper block and is adapted to fit the threaded rod.

[0013] Furthermore, the insulating support is made of ceramic material.

[0014] The technical effects and advantages of this utility model are:

[0015] 1. This utility model inserts the insulating support through the through-hole so that one end of the insulating support reaches one side of the starting flange head. A rotating cap is then connected to the outer thread on one side of the insulating support and secured. The insulating support is then rotated to align the second mounting hole on the disc with the first mounting hole. The insulating support is then secured to the starting flange head using a fixing bolt. This helps maintain the original shape and size of the starting flange head, ensuring the integrity of electrical insulation and physical isolation, preventing safety hazards such as short circuits and arc discharges caused by deformation, and protecting personnel and equipment.

[0016] 2. When water needs to be removed from the bus duct, the motor is started to rotate the threaded rod. The threaded rod then rotates, cooperating with the threads in the scraper block to move. The scraper block then pushes the water out of the bus duct to both sides. The water is then directed to both sides through the water diversion trough, and the water is then drained out through the water outlets on the limit reinforcement strips. This improves the electrical safety of the bus duct, prevents water from entering the bus duct, maintains the good insulation properties of the insulation material, effectively prevents electrical faults such as short circuits and arc discharges, and protects personnel and equipment from hazards such as electric shock and fire.
