EHV and UHV hybrid multifunctional transmission line training device

Abstract

The invention discloses an ultrahigh-voltage and extra-high voltage mixed type multifunctional power transmission line training device. The ultrahigh-voltage and extra-high voltage mixed type multifunctional power transmission line training device comprises three towers, tensible glass insulators, a pendency composite insulator, a V-string glass insulator, a six-split wire, a four-split wire and a ground wire. The three towers are each fixedly connected with a transverse cross arm. Vertical projections formed by the first cross arm, the second cross arm and the third cross arm on the ground are parallel, the pendency composite insulator and the V-string glass insulator are fixed to the ends, far away from the second tower, of the first left cross arm and the second right cross arm respectively, the two ends of the six-split wire are connected with the tensible glass insulators at the first left cross arm and the third left cross arm respectively, the two ends of the four-split wire are connected with the tensible glass insulators at the first right cross arm and the third right cross arm respectively, and the two ends of the ground wire are connected to the top end of the first tower and the top end of the third tower respectively. According to the ultrahigh-voltage and extra-high voltage mixed type multifunctional power transmission line training device, all high-altitude overhauling training items of 500 kV, + / -500 kV, + / -800 kV can be achieved.

Description

technical field [0001] The invention relates to the technical field of electric power teaching appliances, in particular to an ultra-high voltage and ultra-high voltage hybrid multifunctional transmission line training tower device. Background technique [0002] Since the traditional operating transmission lines are live, it is not conducive to technical skills training, especially the ultra-high voltage and ultra-high voltage transmission lines. The voltage level of EHV transmission lines is 500kV, and the voltage level of UHV DC transmission lines is 800kV. The load is very heavy during operation, and it is not easy to cut off the power. In order to solve the problem of technical skills training for ultra-high voltage and ultra-high voltage line operation, maintenance and repair personnel. An alternative approach is needed to enable O&M and maintenance personnel to carry out technical skills training. For this reason, through in-depth research, we designed a hybrid type...

Problems solved by technology

Therefore, such a single training tower facility is far from being able to meet the skills training of transmission and inspection personnel. There is a large gap and shortage of skills training for new equipment testing and hardware replacement in line maintenance.
