Embodiment Construction
[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0015] A manufacturing device for radial circular defects in cables, such as figure 1 and figure 2 As shown, it includes a metal fixing ring 1, a positioning magnet 2, a cutting wire 3, a wire fixing end 4, a rotating shaft 5, a transmission motor 6, a limit force sensor 7 and a control circuit 8. The metal fixing ring is composed of two open semi-circular rings, and positioning magnets are installed at the openings of the two semi-circular rings to realize the closing function of the two semi-circular rings. A depth indicator (unit: mm), a depth advance control button (up arrow: the depth increases by 1 mm each time it is pressed), and a depth retreat control button (down arrow: each time the depth is reduced by 1 mm) are installed on the surface of a semi-circular ring ), zero button (letter R: used to reset the depth reading to zero), limit force sensor...

The invention relates to a manufacturing device for a radial annular defect of a cable. The manufacturing device is technically characterized by comprising a metal fixing ring, a positioning magnet, acutting steel wire, a steel wire fixing end, a rotating shaft, a transmission motor, a limiting force sensor and a control circuit, the metal fixing ring is composed of two semi-circular rings with openings, the positioning magnet is installed at the opening of each semi-circular ring, and a depth indicator and a control button are installed on the surface of one semi-circular ring and connectedwith a control circuit installed in the semi-circular ring. A guide groove is formed in the metal fixing ring, a circle of cutting steel wire is installed in the guide groove, the two ends of the cutting steel wire are connected with the steel wire fixing end and the rotating shaft respectively, the output end of the transmission motor and the rotating shaft are installed together, and the controlcircuit is connected with the transmission motor and the limiting force sensor. The influence of a manual processing method on cable defect manufacturing is eliminated, the manufacturing accuracy isimproved, and compared with manual defect manufacturing, the manufacturing time cost is saved.
Description
technical field [0001] The invention belongs to the technical field of XLPE cables, in particular to a manufacturing device for radial circular defects of cables. Background technique [0002] With the development of urban power grids, XLPE cables continue to play the role of transmitting electric energy. While gradually replacing oil-paper insulated cables, they also face many problems. Among them, failures caused by mistakes in the installation process occur from time to time, and even serious accidents such as explosion of the cable head and fire in the cable trench. Therefore, it is very important to study the weak parts of the cable installation, that is, the possible defects in the cable accessories. . Among the many defects in the cable, the ring defect of the cable has a great influence on the service life and life of the cable. Therefore, the simulated production and experimental analysis of cable ring defects are of great significance to practical engineering. ...
