Abstract

The invention discloses a comprehensive online monitoring device and method for a switch cabinet. The switch cabinet comprehensive online monitoring device comprises an intelligent early warning mechanism, wherein a base is fixedly installed at the bottom part of the intelligent early warning mechanism, a top plate is fixedly installed at the top part of the base through an installation column, and the front end face of the intelligent early warning mechanism is provided with a traveling wave signal collector, a fault point range finder and a partial discharge signal collector. According to the comprehensive online monitoring device and the method, when in use, a fastener between mounting piece on the outer surface walls of a plate IV and a plate I is loosened, and the operation of a maininterface of the intelligent early warning mechanism can be carried out; and a plate II, a plate III and the plate IV can be wrenched in sequence from the left side to separate cards on the inner surface walls from the installation column, at the moment, a cover closing mechanism composed of the plate I, the plate II, the plate III and the plate IV can be separated from the intelligent early warning mechanism and integrated with the intelligent early warning mechanism, an operator can operate and overhaul the device from a proper position, and therefore the using effect of the comprehensive online monitoring device for the switch cabinet is improved.

Description

technical field

[0001] The invention relates to the technical field of switch cabinets, in particular to a comprehensive on-line monitoring device and method for switch cabinets. Background technique

[0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. load shedding.

[0003] At present, there are still deficiencies in the existing comprehensive on-line monitoring devices for switch cabinets. , which makes the switchgear comprehensive online monitoring device often inconvenient in maintenance or wiring, thereby reducing the use effect of the switchgear comprehensive online monitor...
