A high voltage circuit breaker comprises a vacuum interrupter module, a drive module, and an actuator. The vacuum interrupter module has a vacuum interrupter housing and a pair of electrical contacts disposed in the vacuum interrupter housing. At least one of the pair of electrical contacts is movable relative to the other of the pair of electrical contacts to engage and disengage the electrical contacts from one another for switching a high voltage on and off. The drive module has a drive module housing and a drive member coupled with the at least one movable electrical contact. A central part of the drive member is disposed in the drive module housing and insulated from an ambient air. The actuator is coupled to the drive member and moves the pair of electrical contacts relative to one another.

A system comprises a drone having autonomous drive capability and an assist vehicle (AV) for transporting the drone in an assisted drive mode in which the drone is held at, and transported by, the assist vehicle. Control hardware and software are programmed to determine drone travel over a route having a first route section in which the drone travels autonomously and a second route section in which the drone travels in the assisted drive mode.

Proposed is technology that enables the linked use of a camera and sensor system in a train image monitoring system. A train image monitoring system is characterized by, in a train monitoring system (100), the following: a control device (271) comprising a means for managing the device configuration of the system, a means for receiving data from each device, a means for determining the control contents of each device, and a means for transmitting a control instruction to each device; a recording device comprising a means for receiving data from each device, a means for recording received data, a means for reading out recorded data, a means for transmitting read-out data, and a means for receiving a control instruction; and a display device comprising a means for receiving data from the recording device, a means for displaying received data on a screen, a means for detecting a user operation, a means for transmitting the contents of a user operation, and a means for receiving a control instruction.

A charging station for charging an electric bus is provided which includes a power rail extending along an axial direction above a plurality of electric buses parked in a parking space, a pantograph disposed in a lower portion of the power rail to be movable horizontally along the axial direction and expandable in a gravitational direction from above the electric bus to electrically contact the electric bus, and a controller configured to calculate a charging sequence of the plurality of electric buses based on position information of the plurality of electric buses, wherein the controller is configured to control horizontal movement of the pantograph and electrical contact with the electric bus according to the charging sequence so as to supply the power applied from an external power network through the power rail to the electric bus through the pantograph.

A system for monitoring electrical contacts for an overhead trolley line may include a wear sensor arranged such that an electrical contact on a vehicle or work machine for contacting the overhead trolley line is continually or periodically in its line of sight. The wear sensor may be configured to capture spatial data defining the surface profile of the electrical contact. The system may also include a data processing module configured to receive the spatial data and identify a defect in the electrical contact based on the spatial data.

A current collector for a non-track-bound, electrically driven vehicle for feeding electrical energy from a two-pole overhead line system with two contact wires. Two upper arms are rotatably connected to an adjustable lower arm by toggle joints. Each upper arm carries a contact rocker for contacting the contact wires. Coupling bars are rotatably connected to the upper arms and articulated so that adjustment of the lower arm forces adjustment of the upper arms. A compensating rocker compensates for a height difference between the contact rockers with a rocker stand and a rocker beam. The rocker stand can be rotatably connected to the vehicle and the rocker beam is connected to the coupling bars by way of compensating joints on either side of the rocker joint. At least one stop element limits a rotational movement of the rocker beam about a rocker joint axis of the rocker joint.

A method for controlling the charging of one or more electric vehicles at one or more charging stations in a geographic locality includes determining if the charging event of an electric vehicle of the one or more electric vehicles increases a demand billing rate. The demand billing rate may be a cost per unit of energy in the locality. The method also includes charging the electric vehicle at the charging event such that the demand billing rate is not increased.

A method for monitoring the on-board battery of a rail vehicle. The state of charge of the on-board battery is regularly ascertained in an automated manner and is compared with a desired state of charge value. In case the ascertained state of charge value drops below the desired state of charge value, a message is generated for initiating measures for charging the on-board battery.
