Description

Power cable bending test device

Technical Field

The invention belongs to the technical field of power test devices, and particularly relates to a power cable bending test device.

Background

The power cable plays a role of power transmission as important equipment for power transmission. The cable should have certain bending property to meet the requirement of actual installation and laying. Meanwhile, the user of the cable should lay and install the cable according to the existing national standard or the statement of the manufacturer, and if the bending radius of the installation and laying is too small, the cable will have the hidden trouble in the operation process. In recent years, most types of cables have a clear requirement for the radius of the flexural plate, for example: GB/T22078 "rated voltage 500kV (Um 550kV) cross-linked polyethylene insulated power cable and accessories part 1: rated voltage 500kV (Um 550kV) cross-linked polyethylene insulated power cable and its accessories-test methods and requirements-are specified in 12.4.4 "bending test": "the cable sample should be bent at room temperature at least one full turn around the test cylinder (e.g., the drum), then repositioned without turning the shaft, and then the sample bent in the opposite direction, and the process repeated. This repeated bending should be performed a total of three times. The diameter of the test cylinder should be no more than 25(D + D) + 5% for lead, lead alloy and corrugated metal sheathed cables, where D is the nominal diameter of the conductor, mm (see 6.8); d is the nominal outer diameter of the cable, mm (see 6.9). After the bending test is finished, the accessory is mounted on the cable, and the assembly test is carried out at room temperature and meets the 12.4.5 requirement ". Other voltage class cable standards also specify the bend radius of the cable. However, for the bending radius test, a cable reel and a rewinder are generally adopted in a factory and a test mechanism, the bending radius is inaccurate, and the operation is inconvenient.

Meanwhile, the existing bending test device is mostly realized by adopting a cable reel and a rewinder, and has the defects of large bending radius error, large occupied area of equipment and inconvenient operation.
