Description

A kind of intelligence presses magnetic field pressure noncontact location switch cubicle

Technical field

The present invention relates to a kind of intelligence press central switch cabinet technical equipment field, particularly to a kind of intelligence Energy is pressed magnetic field pressure noncontact location switch cubicle.

Background technology

Along with the popularization of intelligent grid, market urgent needs is correlated with smart machine, the intelligence of tradition transformer station The intelligent Application of energyization transformation and new design transformer station is imperative；Power switch cabinet is electric power neck One of equipment that territory is the most commonly used, its reliability, handling, safety can directly affect power system Safe operation and trouble-saving；Medium Voltage Switchgear is a kind of switch electrical equipment in power switch cabinet, Foreign current is master switch in wire is introduced into cabinet, connects with each branch subsequently into sub-control switch； Each branch needs to arrange instrument, control to control with protection assembly, monitoring assembly, various AC circuit breakers etc. Components and parts processed, are controlled circuit, protect, measure, measure, monitoring etc..

Medium Voltage Switchgear is along with the growth of the time of use, and the running status of switch cubicle can run down, respectively Plant the fault symptom of a trend can progressively manifest；During mechanical breakdown, insulation fault, heating accident, burst accident are Compress switch major failure and the accident source of cabinet；Due to natural cause (thunderbolt, condensation), the manufacture of equipment Defect, the mistake of design and installation, repair quality is defective or operation maintenance is improper and the short circuit that causes Or irregular operating state, all may cause accident in power system.Fault once occurs, it is necessary to Excise rapidly and selectively fault element.Medium Voltage Switchgear self there is also potential safety hazard, middle pressure Switch cubicle cabinet door in running is to close all the time, and operations staff cannot know main electrical scheme shape in cabinet In state, switch cubicle, the actual working state of various components and parts cannot be found out；And condensation problem is in insulation thing Accounting for sizable ratio in therefore, the Temperature and Humidity Control in switch cubicle is also non-negligible, insulating part Filth causes insulating properties to reduce；Equipment state and life-span cannot understandings promptly and accurately, it has to need Wanting electrical management person that scene carries out artificial timing maintenance, some potential faults can't be found in time, This is also the problem that puzzlement electric power safety produces for many years；Owing to holding very much when Medium Voltage Switchgear breaks down Easily causing power grid accident and cause great economic loss, in prior art, widely used maintenance mode is Periodic inspection and afterwards overhauling, maintenance can not the fault of discovering device early and defect afterwards；Periodically Lacking of property of maintenance, it is impossible to pre-protrusion-dispelling, with accident, also tends to cause the very big wave of man power and material Take, simultaneously because excessive maintenance is also possible to bring new potential safety hazard.
