An external racking device for remotely racking in and racking out an electrical circuit breaker from a cabinet. The racking device includes a motor head equipped with an electric motor, the electric motor being provided with a rotating shaft ended with an adaptor, and arranged to be coupled with a racking mechanism of an electrical circuit breaker, so that when driven in rotation, the shaft, depending of rotation, trigger either the racking in or the racking out of the circuit breaker from the cabinet. The external racking device further includes monitoring means intended to enable or to disable the operation of the electric motor depending on the status of a circuit breaker to be racked in or racked out from a cabinet.

A power distribution system is releasably secured to a power distribution panel, and includes a circuit breaker to detect a fault condition and to automatically move a circuit breaker switch from the ON position to the OFF position. The power distribution system further includes a backplane connector to provide connection to the power distribution panel and an interconnect mechanism to connect the circuit breaker to the backplane connector when the circuit breaker is moved from a disengaged position to an engaged position with respect to the backplane connector. The power distribution system further includes a guard coupled to the interconnect mechanism and configured to cover portions of the enclosure of the circuit breaker. The guard further prevents the circuit breaker switch from moving from the OFF position to the ON position until the interconnect mechanism connects to the circuit breaker to the backplane connector.

An apparatus for monitoring a switchgear includes: an input unit; a processing unit; and an output unit. The input unit is provides the processing unit with a monitor infra-red image of the switchgear. The processing unit implements a machine learning classifier algorithm to analyse the monitor infra-red image and determine if there is one or more anomalous hot spots in the switchgear. The machine learning classifier algorithm has been trained based on a plurality of different training infra-red images. The plurality of training infra-red images include a plurality of modified infra-red images generated from a corresponding plurality of infra-red images, each of the modified infra-red images having been modified to remove an effect of obscuration in the image. The output unit outputs information relating to the one or more anomalous hot spots.

The present disclosure provides a quick connect and disconnect cable junction box, including: a box body, insulators, copper busbars, connection wires, T-shaped cable terminals, linear adapters, and an insulation spacer. The insulators, the copper busbars, the connection wires, and the T-shaped cable terminals are positioned inside the box body. The linear adapter includes a conductive rod, an insulation layer, a quick engagement connector, and a housing. One end of each of three linear adapters is electrically connected to the T-shaped cable terminal inside the box body. The three linear adapters, three T-shaped cable terminals, three connection wires, and three copper busbars form a three-phase electrical path. During operation, the three copper busbars are correspondingly connected to three phase lines of an incoming cable of a ring main unit; and the three linear adapters are engaged with quick connectors of three bypass cable connectors via the quick engagement connectors thereof. The quick connect and disconnect cable junction box has a simple structure and low cost, and is easy to build. Using the present invention greatly reduces the installation distance of a flexible bypass cable, thus effectively addressing the difficulty of installing a flexible bypass cable to a power supply point over a long distance and improving operation efficiency of rush repair.
