Unipole Conductor Rail Expansion Joint

Temperature Compensator:

The conductor rails temperature compensation section is also called the thermal expansion compensation section, which is used to compensate for the change of the length of the wire caused by the temperature change. Set when the light rail length exceeds 150 meters and set when the heavy rail exceeds 200 meters.

Unipole Conductor Rail Expansion joint is caused by the linear deformation (profile extrusion to the top) and the shrinkage (profile shrinkage) caused by the sliding contact line during thermal expansion and contraction according to the sliding contact line operating in different temperature environments. And designed. It consists of two movable segments connected directly to the main body of the trolley line.

The basic principle is that it consists of a pair of opposing static slides and dynamic slides to form a transition body that conforms to the cross section of the conductor rails body, and is free to move linearly when the ambient temperature of the conductor rails changes. Since the static sliding piece and the dynamic sliding piece are stacked, no matter how it is stretched and contracted, it can give the collector's brush a straight transition plane, thereby overcoming the narrow range of expansion caused by the expansion joint at an earlier stage. The electric brush overcomes difficulties and causes power failure, and the contact surface becomes small and jumps. Since the static sliding piece and the dynamic sliding piece are directly connected to the sliding wire body at the same time, two sliding guiding rods are disposed at the same time to guide the static sliding piece and the dynamic sliding piece, so that it has good coaxiality. At the same time, two soft cables connected in parallel with the sliding tabs are arranged above the two ends of the static sliding vane and the dynamic sliding vane, thereby stabilizing and increasing the current carrying capacity of the expanding section, so that the entire system is not set by the expansion section. And affect the rated current capacity of the entire line.

The expansion range of the expansion section can be adjusted between 0 and 200mm, and the expansion coefficient can be absorbed when the material of the sliding guide rail is aluminum or copper, the expansion point is 150 meters/section, and the ambient temperature is -40°C to +115°C. The telescopic distance is induced and the current collector can pass smoothly without affecting the power supply quality.
