Description

Contact net compensator action detection device

Technical Field

The utility model relates to a power supply contact net detection area especially relates to a contact net compensator action detection device.

Background

The contact net compensator is a general name of a compensating mechanism for automatically adjusting the tension of a contact wire and a carrier cable and a braking device thereof.

When the temperature changes, the clue expands with heat and contracts with cold under the influence of the temperature change, and then extends or shortens. Because the compensators are arranged at the anchoring positions of the cables at the two ends of the anchor section, the tension of the cables can be automatically adjusted and the cable sag can be kept to meet the technical requirements under the action of the gravity of the falling weight string, so that the stability and elasticity of the contact suspension are improved, and the operation quality of the contact network is improved.

The compensator consists of a compensating pulley, a compensating rope, a pestle ring rod, a weight block and a connecting part. The compensating pulley is divided into a fixed pulley and a movable pulley (with the same structure), the fixed pulley changes the stress direction, and the movable pulley can save labor and move the position except changing the stress direction. The pulleys are typically mounted with bearings.

The compensator is serially connected with the fixing positions of the two ends of the cable in the anchor section and the support, and has different compensator structures according to different contact suspension types.

The compensator keeps the tension of the cable balanced by the gravity of the weight string. When the temperature changes, the balance weight string rises and falls due to the stretching of the cable wire, and when the balance weight string rises and falls beyond the allowable range, the compensator loses the compensation effect due to the fact that the bottom surface of the balance weight string contacts the ground due to too much falling or the ear ring hole of the balance weight rod is clamped in the fixed pulley groove due to too much rising. Therefore, the lifting range of the weight string is limited by the values of a and b of the compensator.

The contact net anchor segment can shift under the following factors: 1) the tension on two sides of the fixed point of the central anchor knot is unbalanced, so that the anchor section deviates; 2) the contact suspension weight is distributed obliquely due to the slope of the roadbed in the anchor section; 3) wind or pantograph impacts.

The offset of the anchor section of the contact net can cause the following hazards: the elastic performance of contact suspension is damaged, and high-speed current collection is not facilitated; the pantograph is easy to be out of bow or drilling bow accidents, because the deviation of the anchor section can cause the deviation of the wrist arm, and the pull-out value (the 'Z' -value) of the positioning point is changed; the serious deflection of the cantilever can cause the insufficient distance between the carrier cable and the grounding object to cause discharge, and serious contact network accidents such as the action of a circuit breaker at the feed side, the disconnection of the carrier cable end and the like are caused.

The central anchor is generally arranged in such a way that the tensions of the cables at the two sides of the fixed point of the central anchor are equal to the greatest extent and are as close as possible to the middle of the anchor section. Under special conditions, when the length of the anchor section is shorter, a central anchor knot is not needed, one end of the anchor section is provided with a hard anchor, and a thread at the other end is provided with a compensator, so that the hard anchor is equivalent to the central anchor knot.
