An integrated high-voltage electrical equipment

Abstract

The invention discloses an integrated high-voltage electrical device, which includes a high-voltage electrical module for providing the corresponding operation of the high-voltage electrical box, a bus breaker module for providing the corresponding operation of the bus circuit breaker box, and a bus disconnecting module for providing the corresponding operation of the bus isolating switch box. The bus disconnector module for operation and the auxiliary high-voltage module for providing the operation corresponding to the auxiliary high-voltage box; wherein, the high-voltage electrical module, the bus disconnector module, the bus disconnector module and the auxiliary high-voltage module are integrated in the same box and share the same The protection circuit is connected with the high-voltage bus through the protection circuit. It can be seen that compared with the original distributed cabinets, this equipment has been compressed in a large area in terms of box volume. While maintaining the original functions, it saves the installation space and installation weight of the equipment under the vehicle. Compared with the original decentralized scheme, the large integrated high-voltage electrical box is more suitable for the requirements of small size and light weight of the equipment under the vehicle of modern urban rail transit vehicles.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an integrated high-voltage electrical equipment. Background technique [0002] Urban rail transit The subway, light rail and other means of transportation are part of the passenger transportation system within the city, which refers to the passenger rail transportation system built in the economically developed and densely populated economic area that can realize public transportation operation, convenient, fast and large capacity. [0003] With the development of the rail transit field, in all stages of commissioning and operation of urban rail vehicles, there are requirements for modularization, integration and miniaturization of vehicles; in the whole life cycle of operation, maintenance and repair, the cost of vehicles is the lowest requirements. Under-vehicle high-voltage electrical equipment of urban rail transit vehicles mainly includes high-voltage electrical box, b...

Problems solved by technology

Since the boxes are independent of each other, and the internal devices are also independent of each other, high-voltage electrical equipment often needs to occupy a large area under the car, which brings greater pressure on the layout space under the car
