Abstract
The utility model belongs to buses for power transmitting and distributing with high voltage and high current, particularly phase splitting enclosed buses of a fully connecting type of a power transmitting and distributing device in a large or a medium power plant (station) with the rated voltage less than 24KV and the rated current less than 30000A. A conductor is supported by an insulator in a bus shell. The insulator fixed to the bus shell of each phase presents a triaxial Y-shaped space to support the conductor. The included angles of the three insulators are 120 DEG. One of the insulators is supported at the lower part of the conductor. Both ends of the bus shell of each phase are connected with short circuit boards to form three-phase splitting enclosed buses of a fully connecting type with the advantages of safe operation and high reliability.
Description
The utility model belongs to high-voltage great-current power transmission and distribution bus, particularly a kind ofly is used for that rated voltage 24KV is following, rated current is 30, the fully connecting phase-splitting enclosed busbar of the equipment for power transmission and distribution of the large and medium-sized power plant (station) that 000A is following.
Usually, generator outlet and electrical power distribution busway adopt expose in the majority in power plant's (station).More and more higher at the generator single-machine capacity, under the increasing situation of electric line capacity, the magnetic field that bus current produces is also increasing to surrounding buildings steel structure and environmental impact, nonserviceable down, the huge electric power that the busbar short-circuit electric current produces makes the insulation supporting structure of conventional usefulness be difficult to bear.Therefore, in the measure of bus manufacturing, installation and maintenance and assurance safe and reliable operation, also become increasingly complex.
The purpose of this utility model is to overcome above technical deficiency, and provides electromagnetic shielding good, and alternate electric power is little, is convenient to installation and maintenance, fully connecting phase-splitting enclosed busbar that security reliability is high.
Task of the present utility model is, fully connecting phase-splitting enclosed busbar, in bus shell by the insulator support conductor, fixing insulator becomes three-dimensional " Y " shape space supporting conductor on every phase bus shell, 120 ° each other of 3 insulator angles, wherein 1 insulator support is under conductor, and two ends connect short board formation three-phase and connect the phase-splitting enclosed busbar entirely on each phase bus shell.
Fully connecting phase-splitting enclosed busbar becomes supporting bus-bars conductor in three-dimensional " Y " shape space at bus shell by insulator, make bus in running, have the three-dimensional degree of freedom, especially when short circuit, the suffered electric power of conductor is very little, make insulator not fragile, bus shell has good shielding action, has reduced shell and has reached alternate electromagnetic field intensity outward.
