Intelligent medium-voltage switchgear cabinet

Abstract

The invention relates to the technical field of a switchgear cabinet, in particular to an intelligent medium-voltage switchgear cabinet. The intelligent medium-voltage switchgear cabinet comprises a cabinet body, an electric operation and wireless control unit, an on-line monitoring protection and control unit and an interlocking unit, wherein two fixing support frames with guide holes are arranged in the cabinet body; a rotatable terminal frame is arranged between the two fixing support frames; each of two sides of the terminal frame is provided with a flanging; one end of each flanging is connected with the corresponding support frame through a rotating device, and the other end of each flanging is provided with a first locking screw bolt capable of moving in the corresponding guide hole; the rotating device comprises a first installing hole, a first positioning lug boss, a second installing hole and a second locking screw bolt; the first installing hole is formed in the corresponding fixing support frame; the first positioning lug boss is arranged on the corresponding flanging; the second installing hole is formed in the first positioning lug boss; the second locking screw bolt penetrates through the first installing hole and the second installing hole; the rotating device also comprises a locking device for locking the second locking screw bolt; and the locking device comprises a locking screw nut. Therefore the intelligent medium-voltage switchgear cabinet has the advantages that the secondary wiring is convenient, and the security performance is high.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to an intelligent medium-voltage switch cabinet. Background technique [0002] Medium voltage switchgear is a common indoor complete set of equipment for medium and low voltage power distribution systems, and it is widely used in systems with rated voltages of 12kV and 7.2kV three-phase AC 50Hz. However, most medium-voltage switchgears are only traditional structures, which can only perform simple power transmission, control, measurement and protection. The core component switch is still operated manually. It is difficult to realize the automation and intelligence of the switchgear through online monitoring; although there are intelligent switchgears at present, when performing secondary wiring, the narrow space will lead to inconvenient wiring for workers, which not only increases the labor time and intensity of workers , affecting work efficiency, and the door of the swit...

However, most medium-voltage switchgears are only traditional structures, which can only perform simple power transmission, control, measurement and protection. The core component switch is still operated manually. It is difficult to realize the automation and intelligence of the switchgear through online monitoring; although there are intelligent switchgears at present, when performing secondary wiring, the narrow space will lead to inconvenient wiring for workers, which not only increases the labor time and intensity of workers , affecting work efficiency, and the handcart door and the front and lower door of the switchgear are prone to be opened by mistake in the charged state, which greatly affects the safety of operation
