Feed type closed bus duct

Abstract

A feed type closed bus duct comprises a bearing plate, a protection shell and fine adjustment devices, the protection shell is located over the bearing plate and is in an I shape, the protection shell and the bearing plate are connected through a plurality of fine adjustment devices which are evenly distributed, and a plurality of wire row holes which are evenly distributed at equal intervals are formed in the protection shell. Sealing covers are arranged at the positions, corresponding to the wire row holes, of the left end and the right end of the protection shell, the left end and the right end of each wire row hole are each provided with a detection space in a communicating mode, and a feed device is arranged in each detection space. The bus bar is inserted into the protection shell through the wire bar hole, the feed device corresponding to the bus bar is attached to the bus bar, the feed devices at the two ends of the wire bar hole are electrically communicated to form a complete detection circuit, and when a plurality of bus ducts are assembled and used, the distance between the protection shell and the bearing plate is adjusted through the fine adjustment device. When the bearing plate inclines due to the hoisting problem, the inclination angle of the protective shell is properly adjusted, so that the protective shell is kept in a horizontal state.

Description

technical field [0001] The invention relates to the field of electrical equipment, and particularly provides a feed-type closed bus duct. Background technique [0002] The busway is a closed metal device composed of copper and aluminum busbars, which is used to distribute large power to each component of the dispersion system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk projects. With the emergence of modern engineering facilities and equipment, the power consumption of all walks of life has increased rapidly, especially many high-rise buildings and large workshops. With the emergence of workshops, traditional cables as transmission conductors can no longer meet the requirements in high-current transmission systems, and the parallel use of multi-channel cables brings a lot of inconvenience to on-site installation and construction connections. The plug-in bus duct emerges as a new type of distribution wire. Compared with the t...

[0003] However, the existing busbars are all in a fixed mode, and the number of busbars is fixed. The same number of busbars are used in the power transmission of different powers. When the transmission power is too large, the number of busbars will be relatively small. , the load of a single busbar is large, which is easy to cause damage to the equipment, and the transmission power is too small, the number of busbars will be relatively large, and the load of a single busbar is too small, resulting in waste of equipment use; in actual use According to the usage specification, the busway needs to be hoisted at a position one meter below the ceiling, and multiple busway connections are often required in power transmission. The positional relationship needs to be calculated in advance before hoisting. However, in actual use, uneven walls, The error generated during hoisting may cause the busway not to be in the horizontal position. When the two busways to be connected have a busway that is inclined, the butted interface cannot be kept horizontal, and the forced connection will cause distortion, resulting in shearing The force will reduce the service life of the device, so it needs to be recalculated and re-lifted, which wastes a lot of manpower and material resources
