Structural features: the series of busbar bridge has excellent anti short circuit performance, due to the protection of aluminum (or weak magnetic plate shell to effectively decelerate the weak or vortex circulation caused by heating structure, reduce the busway shell temperature, reduce power loss, enhance load, light electric power reduction.

The series of busbar bridge structure is advanced, the installation of the upper part or the lower part of the repair can be put on any bus bar bridge, for large current indoor busbar bridge on both sides of the casing and lower or upper, with ventilation shutters to strengthen the heat radiation and reduce the temperature rise.

The safety performance is significantly improved by using double insulation and multi point connection of the shell, so that the maintenance work is significantly reduced.

In order to solve the variable transformer, negative effects of vibration generated during the operation of the generator and power distribution cabinet of bridge bus, and the bus bar bridge junction with the soft connection or copper braid, between the shell with rubber pads to reduce vibration; for the maternal line bridge ontology, in the system installation of shock reducer, of insulator and the conductive heat to realize elastic support, better avoid enclosure produced the mechanical vibration and seismic wave for the closed bus to bring destruction.

Bus bar bridge heat transfer thermal radiation, in order to make good use of heat radiation, the shell of the bus bridge in table spraying grayish package paint to reduce the absorption of visible light; in the busbar surface black spray paint to strengthen internal heat radiation to the housing, and to prevent the corona.

In order to avoid the winter indoor and outdoor temperature changes resulting from accidental condensation phenomenon, in the wall at the setting wall bushing, the outdoor and indoor busbar completely isolated; vertical installation, flange, horizontally mounted, flange on the outer.

In order to make the bus bar bridge self vibration frequency to avoid generate vibration frequency range (for a single bus the resonance frequency range for 35~135Hz), and the effect on the bus electric power decreases, reasonably determine the span between insulators. Selection of insulator type, size and strength grade.

In order to facilitate the user, can be based on user needs, at the generator outlet and at the side of the excitation transformer into a current transformer, to facilitate the user to detect the current.

Main technical parameters

The insulation resistance: each busbar unit value of insulation resistance should be greater than or equal to 1000M (2500V megameter).

O dielectric strength: first section of busbar trunking factory were the love 1 minute power frequency withstand voltage test, power frequency withstand voltage and lightning impulse withstand voltage value, see table.

The bus bridge in high strength due to ceramic is used as the phase separating material so that it can withstand strong electric stress and thermal stress.

The bus bridge in the long term by the rated current, does not exceed the extreme list up the conductive parts of temperature.

The grounding system: IEC364-5-54 meet the requirements for the grounding system.

The protection grade: outdoor type: IP40 (with rain cover)

O loading performance: the rated current, the shell temperature rise with GB763-90 the AC high-voltage electrical appliances in the long-term fever "standard requirements.

The short circuit performance: dynamic thermal stability test in accordance with GB2706-89 "AC high voltage electrical dynamic thermal stability test method" standard.
