Abstract

The invention relates to the technical field of power distribution, and discloses a medium-voltage switch cabinet and a power distribution system. The medium-voltage switch cabinet comprises a switch cabinet, a bus chamber, a switch chamber and a cable chamber which are mutually independent are arranged in the switch cabinet, an environment factor detection module is arranged in at least one chamber, and the environment factor detection module is used for detecting whether indoor environment factors are abnormal or not; and the medium-voltage switch cabinet also comprises an alarm module, and the alarm module is connected with the environment factor detection module and is used for giving an alarm when the environment factors are abnormal. According to the medium-voltage switch cabinet, through cooperation of the environmental factor detection module and the alarm module, an alarm can be given when an early cause of an electrical fault exists in a room, so that an operator can find the fault cause very early, maintain the fault cause in time and prevent the fault cause from being evolved into the electrical fault, and the probability of the electrical fault can be reduced. Meanwhile, the medium-voltage switch cabinet can reduce the risks of equipment damage, power failure, production halt, disordered life order and the like, so that the continuity and reliability of power supply can be improved.

Description

technical field [0001] The invention relates to the technical field of power distribution, in particular to a medium-voltage switch cabinet and a power distribution system. Background technique [0002] The medium voltage switchgear itself has many fault protection measures, such as current, voltage, load or temperature protection and other means. These protections can effectively eliminate faults and avoid fault expansion. However, there are not many methods for early warning of potential faults in the existing medium-voltage switchgear. It is worth noting that early warning before the failure of the medium-voltage switchgear and the alarm of some electrical failures in the bud can avoid failures and reduce failure losses to a greater extent. Exemplarily, an alarm is issued when the electrical connection is slightly loose, the contact resistance is increased, the electrical insulation is slightly damaged, or partial discharge occurs occasionally, so as to avoid developing...
