The present patent discloses a ventilation and heat dissipation box-type substation, which includes a substation box and a substation box roof, and the surroundings of the substation box roof located on the outside of the substation box and not higher than the height of the top of the substation box. The substation box is provided with a return air inlet, and the inside of the substation box roof is provided with an inner top plate that collects the heat in the substation box. A circulation fan is arranged on the top of the inner top plate and forms a circulation cavity with the substation box roof, and one end of the circulation cavity away from the circulation fan is connected with the outside of the substation box. The present patent effectively avoids the accumulation of heat, which affects the service life of electronic components.

A safety system for high-voltage electrical cabinetry provides active visual and/or audible warnings during maintenance. Load monitors evaluate electrical loads of dedicated power circuits used by an existing automatic lighting system. Light and sound indicators present status information (e.g. indicating maintenance status or normal operating status) to persons in signaling areas based on whether the evaluated electrical loads indicate that at least one lamp is turned on. A common power supply can be used to power the lighting circuit and the indicators. Bridge modules can also be used to monitor the electrical load for different group lighting circuits and report discrete group status information to a programmable logic controller while also sharing the group status information with the other bridge modules. In this case, the indicators present combined status information, for example, indicating a maintenance status if any lamps from any group is turned on.

A switch-gear or control-gear system for medium or high voltage use includes an external housing containing the switch-gear or control-gear system, which is configured for unmanned operation and maintenance. The switch-gear or control-gear system is configured for unmanned operation and maintenance with a robotic system or manipulator and the robotic system or manipulator is provided with a camera system and an image recognition system. The robotic system is provided with a data network or an external data communication interface.

A substation for medium or high voltage includes: switchgear or controlgear with unmanned operation and maintenance; an inner room in which the switchgear or controlgear are located, the inner room being hermetically enclosed by an outer housing, the inner room being locked against the outer housing by an inner, automatically operated door; and a robot system, the robot system being implemented such that an acting area of the robot system is extended from the inner room, partly in an area outside the inner room, but inside the outer housing, where spare parts are stored in a spare parts hand over area, for maintenance.

A switch-gear or control-gear system, in particular a low voltage switch-gear or control-gear system is configured for unmanned operation and maintenance. The switch-gear or control-gear system is configured for unmanned operation and maintenance with a robotic system or manipulator and wherein the robotic system or manipulator comprises a camera system and an image recognition system. The robotic system is provided with a data network or an external data communication interface. The camera is configured to correspond with an image recognition system and to evaluate actual images with adaptive image data, in order to be able to locate and to analyse physical reasons for faults or deterioration of components that might lead to faults.

A substation contains a switchgear or controlgear, in particular at least one low voltage switchgear or controlgear configured for unmanned operation and maintenance. An inner room, where the switchgear or controlgear are located in, is hermetically enclosed by an outer housing. The inner room is locked against the outer housing by an inner, automatically operated door. A robot system is implemented such that the robot system'ss acting area is extended from the inner room, partly in the area outside the inner room, but inside the outer housing, where spare parts are stored in a spare parts hand over area, for maintenance.
