Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] see Figure 1 to Figure 4 , especially see image 3 and Figure 4 , a handcart device for DC metal switchgear shown in the figure includes a frame 10, which is made of profiles. A middle vertical partition 11 is fixed at the middle position of the vehicle frame 10, and the middle vertical partition 11 divides the vehicle frame 10 into a front half 10a and a rear half 10b.

[0023] A middle transverse partition 12 is fixed in the middle of the rear half of the vehicle frame 10 , and the middle transverse partition 12 separates the rear half 10 b of the vehicle frame 10 into a rear upper half 10 ba and a rear lower half 10 bb. The upper rear part 10ba constitutes a secondary component compartment, in which secondary components 20 are installed, and these secondary components 20 are drawn out through the secondary aviation plug-in 30 arr...

Abstract

The invention discloses handcart equipment for direct-current metal switch equipment. The handcart equipment is mainly composed of a propelling mechanism, a main loop contact arm, a coupling loop contact arm, a capacitor chamber, a permanent magnet switch, a secondary component compartment, a secondary aviation plug, a roller and the like. In order to ensure the overall size of the switch equipment, main components need to be considered on the basis of meeting the functions of current transfer, follow current thyristor residual voltage discharge, phase-to-phase and fracture safety distance, magnetic quenching and the like, and the boundary dimensions and arrangement modes of capacitors, permanent magnet switches, poles and secondary components need to be confirmed; and a locking mode of the handcart, the cabinet body valve and the ground knife is designed. And after the appearance is determined, the handcart is designed to be interlocked with the cabinet body mechanism, and the wiringmode of the secondary wire is customized, so that the design of the DC + / -10kV metal switch handcart is completed.

Description

technical field [0001] The invention relates to the field of electric power equipment, in particular to a handcart device for DC metal switchgear. Background technique [0002] At present, the domestic power industry is also vigorously developing flexible DC substations, and the research and development of corresponding DC equipment is imminent. At present, the 10kV DC switchgear system in the electrical industry is still in a blank period. In the switchgear, the handcart device that carries the main closing and opening functions of the equipment is even more blank. In addition, the center-mounted armored switchgear used in the current DC metal switchgear equipment needs to be carried by a carrier vehicle when it needs to be repaired and debugged, and the steps are very cumbersome. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a handcart device for DC metal switchgear in view of the gaps in the existing DC ±10...
