Description

Cable insulation support device for substation maintenance

technical field

The invention belongs to the technical field of electric power equipment, and in particular relates to a cable insulation support device for substation maintenance.

Background technique

The existing insulated cross-arms are divided into two types: domestic and imported. The operation mode generally adopts two kinds of insulated bucket arm trucks with support and pole fixing. During the use of live working personnel, it is pointed out that the existing insulating cross-arm has problems of imperfect cooperation with on-site operation, high difficulty of operation, and high labor intensity. In order to really grasp the real data, we used two commonly used insulating cross-arms to carry out the operation test of replacing the straight cross-arm on the simulated line.

First, use U-shaped hoops to fix the main body of the insulating cross-arm and the pole. After fixing the main body of the insulating cross-arm, install supporting insulators on the A and C phase wires of the three-phase power line respectively; Fixed on the pole, one support cross arm can only complete the fixing after one side of the wire is detached, and the replacement of the cross arm requires the installation of two insulating support cross arms. The patent number is "200920276509.3". The patent document of the hoop is composed of a cross bar, an arc-shaped connector, a chain lock and a card slot. The cross bar is a circular hollow structure made of composite insulating material. Chain locks are respectively fixedly connected to the crossbars on both sides of the arc-shaped connector for fixed connection with the electric pole, and slots are respectively provided at both ends of the crossbar for fixing wires. The above two kinds of crossarms have single functions, and need to install auxiliary parts to complete the work. The operation is relatively cumbersome, the labor intensity of the operators is high, the safety control is difficult, and the insulation support of the cables is not firm, which is prone to loosening and affects normal operations.

The Chinese patent publication number is CN 203932813 U, and the name of the invention is electric power maintenance cable insulation support device, including cross arm, jacket, wire fixing plate, bolt, insulating isolation plate, connecting plate, fixing ring, screw rod, compression piece , the rotating ring, the middle fixed jacket of the cross arm, the two ends of the cross arm are fixed with the wire fixing plate, the insulating isolation plate is fixed on the jacket, and the insulating isolation plate is connected with the fixed ring through the connecting plate, and the fixed ring is divided into It is an upper fixed ring and a lower fixed ring, one end of the upper fixed ring and the lower fixed ring is connected by a rotating shaft, the other end of the upper fixed ring and the lower fixed ring is an open end, and the upper fixed ring and the lower fixed ring are on the open end. An ear plate is provided, and bolts pass through the ear plate to connect the upper fixing ring and the lower fixing. However, the existing electric maintenance cable insulation support device has the problem that the fixation is not firm, and the wires with different wire diameters cannot be firmly clamped.

Therefore, it is very necessary to invent a kind of electric cable insulation supporting device for substation maintenance.
