Description
Technical field
The utility model relates to cable conductor field, specifically a kind of fan-segmentation conductor stock block check adjustable caliper gauge.
Background technology
Along with the further quickening of the quick growth of China's economic and industrialization, Development of China's Urbanization, day by day improve the construction requirements of the infrastructure such as urban distribution network, city, developed regions and provincial capital require that urban central zone uses underground power cable electric energy transmitting one after another.Meanwhile, electric power is prerequisite and the basis of the national economic development, and along with the fast development of national economy, electricity needs increases severely, and net capacity increases suddenly, and power of motor increases, and electric power facility develops towards Large Copacity (high voltage, big current, high frequency) transmission direction.In order to improve the current-carrying capacity of cable, usually adopt the way increasing cross-sectional area of conductor.
The direct current resistance of conductor is an important parameter of examination cable electrical property.But for exchanging the electric cable with large cross-section of transmission, due to the existence of kelvin effect, current density in conductor is not be uniformly distributed, but reduce gradually to center along cable conductor is radial on surface, the current-carrying capacity in conductor is caused to be not increase with cable conductor cross section and increase in direct ratio, but when conductor diameter increases to a certain degree, kelvin effect is serious, conductor in alternating electromotive force circuit is caused to produce loss and the effective resistance that generates heat and AC resistance obviously can be greater than its direct current resistance, external diameter is larger, kelvin effect is more obvious, the ratio causing AC resistance to increase is also larger, depend merely on increasing section and also just lose its practicality and economy.
In order to alleviate the conductor AC resistance increase because kelvin effect causes to greatest extent, effectively reduce the loss heating of conductor, increase the current-carrying capacity of conductor, people have to large size conductor to be carried out in a different manner division processing becomes the conductor be made up of the independent sector of several mutually insulated, the physical dimension of each part obviously reduces, to reach the object reducing AC resistance.Often power cable with cross-linked polyethylene insulation copper core conductor is made milliken conductor in power cable industry, generally have several structures such as four segmentations, five segmentations, six segmentations and seven segmentations, in the majority with sector element.Sectional area due to single sector element only have conductor total sectional area some/mono-, so " kelvin effect " and " proximity effect " of single stock block reduces greatly, thus reach the object reducing conductor AC resistance.
The technological requirement that sector element adds man-hour is higher, process before and after pressing all must strictly be controlled, fan-shaped each fan angle is bad, base angle is bad and cambered surface is incorrect, it is bad after set all can be caused to be shaped, such as not rounding, space is large, fan angle is outstanding, displacement, displacement etc., gap to be caused between insulation course large, all has impact to the Eccentricity control of insulated wire cores and electric property, even cause and puncture.Prior art is to the measurement of fan-shaped size; the multiple professional tool of general employing; measure as adopted arcograph respectively that cambered surface, universal protractor take measurement of an angle, vernier caliper measurement fan is high and fan wide etc.; in actual use procedure; use loaded down with trivial details, high to the requirement of survey crew, also cannot directly measure in process of manufacture; need shutdown to detect, waste time and energy.To the measurement of sector element process, in production run general adopt vernier caliper only respectively high to the fan of sector element, fan wide measurement, sampling and manual stranding each sector element before set is shaped, check its roundness.This method all cannot be measured the fan angle of sector element, base angle and cambered surface, and measuring error is comparatively large, and well cannot control quality, and sampling can cause larger waste, the size fluctuation occurred in process of manufacture also cannot Timeliness coverage.
