Abstract
Provided is a grading ring. The utility model relates to a power cable line's sub-assembly especially relates to a voltage equalizing part on power cable line pylon. The technical scheme of the utility model be realized like this, it includes ring body and support, and the ring body is formed by the semi-ring butt joint of two U-shaped, and the cross-section of ring body is the tubulose, fixedly connected with support on two pairs of corresponding straight edges of ring body, and the middle part of two supports is equipped with the straight flange, and this straight flange is on a parallel with the straight flange axis of equalizer ring, and this straight flange keeps having certain vertical distance with the top surface of equalizer ring, and the middle part straight flange of two supports corresponds the setting. The utility model discloses satisfied 750KV transmission circuit's application in the design, electric field distribution is even, and voltage-sharing and shielding effect improve greatly. Its structural design is reasonable, and the installation is dismantled conveniently in-service use, has reduced manipulation strength, and the trouble probability reduces.
Description
Technical field
The utility model relates to a kind of sub-assembly of power cable line, relates in particular to the equal casting die on a kind of power cable line pylon.
Background technology
At present, mainly being to use the grading ring of metal ring or C type becket structure on the 750KV power circuit, mainly is because voltage is higher, does not have enough big integral type grading ring can adapt to the 750KV transmission line.The grading ring of this structure in use each porcelain vase will be installed one, the use cost height, and fitting operation intensity is big, and the probability that breaks down is also big.
Summary of the invention
The utility model provides a kind of a kind of grading ring that can be used for the semi-ring butt joint of two U-shapeds on the 750KV transmission line at above deficiency.
The technical solution of the utility model is to realize like this, it comprises ring body and support, ring body is formed by the semi-ring butt joint of two U-shapeds, the cross section of ring body is a tubulose, be fixedly connected with support on two corresponding straight flanges of ring body, the middle part of two stands is provided with straight flange, and this straight flange is parallel to the straight flange axis of grading ring, the end face of this straight flange and grading ring maintains certain vertical range, and the middle part straight flange of two stands is corresponding to be provided with.
The diameter of section of described ring body is 70～90 millimeters, and U-shaped bottom arc radius is 350～390 millimeters, and the ring straight flange is 580～620 millimeters.
The vertical range of support straight flange axis and grading ring end face is 255～265 millimeters.
The utility model has satisfied the application of 750KV transmission of electricity circuit in design, and Electric Field Distribution is even, and all pressure and shield effectiveness improve greatly.Its reasonable in design, easy installation and removal has in actual use reduced manipulation strength, and probability of failure reduces.
