Non segregated phase busbar
Basic Info
Model No.: GM
Product Description
The non segregated phase busbar is used for the connection between the factory circuit, substation, small hydropower station, generator and transformer. It can provide a circular structure with a current rating of 4000A and a voltage level of 10KV. The protection level is higher than the traditional common box.
The busbar refers to a product made of high conductivity copper (copper row) or aluminum material for transmitting electrical energy and having the ability to collect and distribute electric power.
This series of enclosed busway has excellent short-circuit resistance. Due to the protection of the aluminum (or weak magnetic steel) casing, it can effectively reduce the structural heat caused by eddy current or circulation, reduce the temperature of the enclosed busbar casing, reduce the power loss, and improve the load. Flow, reduce electric power. The series of enclosed busway has advanced structure, and the installation and maintenance holes can be arbitrarily set on the upper or lower part of the enclosed busbar. For high-current indoor enclosed busbars, ventilation louvers are provided on both sides and lower parts of the casing to enhance heat dissipation and reduce temperature. Rise. Double insulation and multi-point connection grounding of the housing make the maintenance workload significantly reduced and the safety performance is significantly improved.
Features:
The series of enclosed busway adopts bellows expansion joint, which is easy to install and can realize the adjustment of two degrees of freedom in horizontal and vertical directions. It can not only meet the expansion and contraction requirements caused by different temperature drop and thermal expansion and contraction, but also can be used for foundation settlement. The error caused by the compensation compensates for the shortcomings of the conventional sliding type telescopic device, such as poor protection level, troublesome installation, and unreliable operation.
In order to solve the negative impact of the vibration generated by the transformer, generator and power distribution cabinet on the closed busbar, a soft connection or a copper braid is used in addition to the closed busbar, and a rubber pad is added between the outer casing to reduce the vibration; The busway body is equipped with a shock absorber in the system to realize elastic support for the porcelain flat and the conductive row, which better avoids the mechanical vibration generated by the outer casing and the damage caused by the seismic wave to the enclosed bus bar. The heat transfer of the enclosed busway mainly relies on heat radiation. In order to make good use of heat radiation, light gray paint is sprayed on the outer surface of the closed busbar to reduce the absorption of visible light; black paint is sprayed on the inner surface of the closed busbar to strengthen the internal heat to the outer casing. Radiation while preventing corona. In order to avoid accidental condensation caused by outdoor and indoor temperature changes in winter, wall bushings are installed at the wall to completely isolate the outdoor and indoor enclosed busbars; when installing vertically, flanges, horizontal installation, Lan is outside.
In order to improve the allowable operating temperature rise of the enclosed busway, prevent the electrolytic corrosion of the joint in the coastal open air and the galvanic corrosion, reduce the contact resistance, and the closed bus current is greater than or equal to 3000A. All the joints are silver-plated, so that the joint allows temperature. The rise is increased to 65K, which is much higher than the normal temperature rise. In order to avoid the resonance frequency range of the enclosed busway (the resonance frequency range is 35~135Hz for a single busbar) and reduce the electric power acting on the busbar, the span between the insulators is reasonably determined. , select the type, specification and strength level of the insulator.
In order to monitor the temperature of the detachable joint, a sealed observation window is arranged at the connection outlet of the transformer, the generator and the power distribution cabinet and the enclosed busbar, and the temperature is directly measured by the temperature display patch or the far infrared ray temperature measuring device, and the monitoring of the busbar system is performed. Operation.
