Detailed Description
The structure of the three-station isolating switch cabinet with the uninterrupted switching function is described with reference to the accompanying drawings.
The three-station isolating switch cabinet with the uninterrupted switching function is a novel grounding device, and can realize intelligent grounding of a rail transit system through remote or on-site operation of a motor under complete mechanical and electrical interlocking; the discharge unit in the primary chamber releases the residual voltage in the power circuit, so that the risk of load grounding of the device is avoided, and the safety is high; the device is added on the basis of a common three-station isolating switch cabinet, so that the switching of the uninterrupted large-bilateral power supply mode under the condition of power supply in the cross-region can be realized, and the stability of a power supply system is improved.
As shown in fig. 1 and 2, the installation scheme of the three-station isolating switch cabinet is as follows: the three-station visual three-station isolating switch is composed of a single or two three-station isolating switches and a cross-region load switch, and in an electric switch cabinet installed by three-station linkage, copper busbar mode is adopted for the inlet and outlet between the three-station isolating switches and the cross-region load switch. The cable entering and exiting in each switch cabinet is in a lower entering and lower exiting mode. The switch cabinet should be according to the business turn over of cable, the wiring board position and the trompil of reasonable arrangement switch, the wiring and the laying of cable of being convenient for to the fire prevention shutoff measure after should setting up the cable wiring.
According to the embodiment, the isolating switch on the conventional direct current switch cabinet is replaced by the three-station isolating switch with the uninterrupted switching function, the device is applied to a track direct current power supply system, the device is assisted by the installation of the camera, the video monitoring chamber and the discharge chamber, after the power supply of the contact rail or the contact net is stopped, the residual voltage in the power circuit of the device is released through the discharge chamber, and then the motor of the three-station isolating switch is remotely controlled to operate, so that the isolating knife is connected with the grounding contact to realize the short-circuit conduction between the contact rail or the contact net and the running rail, and the grounding operation is completed.
