Description
Technical Field
[0001] The utility model relates to the technical field of bus ducts, in particular to an earthquake-resistant and moisture-proof bus duct. Background Art
[0002] Bus duct is a closed metal device composed of copper and aluminum busbars, which is used to distribute high power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects and has become popular in developed countries abroad, as well as in Hong Kong and Macao in my country. In Guangzhou, Guangdong, my country, more than 90% of the main lines leading to the distribution rooms of buildings with more than 12 floors use bus ducts, and bus ducts are required for 630KVA transformers to distribution cabinets.
[0003] When the bus duct is damp or in a humid state for a long time, water may accumulate inside or on the surface of the bus duct, and condensation may occur. In most cases, the accumulated water and condensed dew may cause discharge, eventually causing the unit to trip, which has an adverse effect on power transportation. At the same time, due to the lack of moisture-proof measures, it is easy to be corroded during use, thus affecting the protection effect of the busbar. In addition, under the influence of external environmental factors, such as earthquakes, some bus ducts lack anti-seismic devices, resulting in damage to the bus duct due to vibration. Utility Model Content
[0004] The utility model aims at the deficiencies of the prior art and provides a bus duct that is earthquake-resistant and moisture-proof to solve the problem that when the bus duct is damp or in a long-term damp state, water may accumulate inside or on the surface of the bus duct and condense. The accumulated water and condensed dew may cause discharge in most cases, eventually causing the unit to trip, which has an adverse effect on power transportation. At the same time, due to the lack of moisture-proof measures, it is easy to be corroded during use, thereby affecting the protection effect of the busbar. Moreover, under the influence of external environmental factors, such as earthquakes, some bus ducts lack earthquake-resistant devices, resulting in damage to the bus duct due to vibration.
[0005] To achieve the above object, the utility model provides the following technical solutions: an earthquake-resistant and moisture-proof bus duct, comprising a bus duct, the bus duct comprising a bus duct body, an earthquake-resistant device and a moisture-proof device, the bottom end of the bus duct body is equipped with an earthquake-resistant device, and the bottom and top surfaces are equipped with moisture-proof devices;
[0006] The anti-seismic device comprises a hanging frame and a rubber pad, the rubber pad is installed on the top surface of the hanging frame, and the bus duct body is installed on the top surface of the rubber pad;
[0007] The moisture-proof device includes a moisture-proof layer, activated carbon, absorbent cotton, a rubber plug, a slide, a roller, a rotating shaft, a bracket and a cover plate. The moisture-proof layer is installed on the top and bottom surfaces of the bus duct body, and activated carbon and absorbent cotton are placed inside. The rubber plug is installed at the front end and the end of the moisture-proof layer. The slide is installed on the side end of the bus duct body and a roller is installed inside. The rotating shaft is installed inside the roller and a bracket is installed at the end. The cover plate is installed on the top surface of the bracket.
[0008] Preferably, the rubber pad is fixedly mounted on the top surface of the hanging frame, and the bus duct body is placed on the top.
[0009] Through the above technical solution, the bus duct is generally hoisted on the top of the building or equipment by a hoisting frame, and a rubber pad is installed between the hoisting frame and the bus duct. The rubber pad is soft, elastic and wear-resistant, which has an anti-seismic effect, protects the bus duct and prolongs its service life.
[0010] Preferably, the moisture-proof layer is provided in multiple groups and is fixedly installed on the top and bottom surfaces of the bus duct body respectively. Activated carbon is placed on the moisture-proof layer close to the bus duct body, and absorbent cotton is placed on the end away from the bus duct body. The rubber plugs are provided in multiple groups and are respectively clamped on both ends of the moisture-proof layer.
[0011] Through the above technical scheme, a moisture-proof layer is set at the top and bottom of the bus duct, and activated carbon and absorbent cotton are arranged in layers inside. The activated carbon close to one side of the bus duct can dry the bus duct, while the absorbent cotton can absorb moisture in the surrounding environment in a humid environment, such as the rainy season, to avoid discharge caused by excessive moisture in the bus duct, resulting in tripping. At the same time, it can also protect the bus duct from moisture corrosion.
[0012] Preferably, the slide groove is fixedly installed on both sides of the bus duct body, and rollers are clamped inside, a rotating shaft is movably clamped at the axis of the roller, and a bracket is fixedly installed at the end, and a cover plate is fixedly installed on the top of the bracket.
[0013] Through the above technical solution, since the wiring position of the bus duct is exposed to the outside, if it is installed outdoors, there is a possibility of leakage when it rains, which poses a safety hazard. Therefore, installing a cover plate on the top of the bus duct can solve the above problem. In addition, the cover plate is removable and will not interfere with the wiring work of the bus duct.
