摘要（英）：

The invention discloses a local discharge monitoring device of a switch cabinet, and belongs to the field of power equipment. The device comprises an ultraviolet detector for detecting an ultraviolet signal generated by the switch cabinet during local discharge, an alarm which is connected with the ultraviolet detector to process the ultraviolet signal by amplifying and noise reduction so as to obtain an alarm control signal which is used for controlling an ultraviolet indication unit of the alarm to indicate the local discharge of the switch cabinet as well as controlling a counter of the alarm to record the local discharge times of the switch cabinet, and a power unit for providing power to the ultraviolet detector and the alarm. According to the technical scheme and compared with other discharge monitoring means, the device has the advantages of being low in price, convenient to mount, and convenient to examine, and has a good popularization prospect.
