Problems solved by technology
The indicator function of the existing contact cabinet is the same as that of the load switch cabinet, which can only identify the live state of the cable, and cannot indicate the live state of the busbar and the direction of the feeder during the transfer of power supply, so it cannot help on-site operators understand the transfer status and operation mode. Increased risk of on-site operations

The invention discloses a state indication device. The state indication device comprises a shell, a signal conversion device, a signal acquisition cable, a master control device and a display device, wherein the shell is provided with an installation cavity chamber, the signal conversion device is arranged in the installation cavity chamber, the signal acquisition cable is connected with an input end of the signal conversion device, the master control device is arranged in the installation cavity, an input end of the master control device is in communication connection with an output end of the signal conversion device, the display device is arranged on the shell, and an input end of the display device is in communication connection with an output end of the master control device. Therefore, by the display device, the live-line state of the cable can be indicated, and meanwhile, the live-line state of a bus of an intermediate-voltage contact cabinet and the state information of a feeding line can also be indicated; and a worker can be helped to timely understand the power conversion state and the running mode during power conversion operation by using the intermediate-voltage contact cabinet, the live-line operation risk of a site is effectively reduced, and the working safety is improved.
Description
technical field [0001] The invention relates to the technical field of power distribution network, in particular to a state indicating device. Background technique [0002] The medium-voltage connection cabinet is a switchgear used to connect different feeders in the medium-voltage distribution network. The connection switch in the connection cabinet is normally open, and the busbars and cables belong to different medium-voltage feeders. When the power supply needs to be transferred, after the busbar or cable is powered off, close the contact switch in the contact cabinet, and then the power supply can be transferred from one feeder to another feeder. The indicator function of the existing contact cabinet is the same as that of the load switch cabinet. It can only identify the live state of the cable, and cannot indicate the live state of the busbar and the direction of the feeder during the transfer of power supply, so it cannot help on-site operators understand the transfe...
