Description
Technical field
The present invention relates to press to press insulation in central switch cabinet technical equipment field, more particularly to a kind of intelligence in a kind of intelligence
Characterize pressure noncontact location switch cubicle.
Background technology
With the popularization of intelligent grid, market active demand correlation smart machine, the intellectualized reconstruction of traditional transformer station with
And the intelligent Application of new design transformer station is imperative；Power switch cabinet is one of the most commonly used equipment of power domain, its
Reliability, handling, security can directly affect safe operation and the trouble-saving of power system；Medium Voltage Switchgear is that electric power is opened
A kind of switch electrical equipment in cabinet is closed, foreign current is introduced into master switch in cabinet by wire, switched subsequently into sub-control
Connected with each branch；Each branch needs to set instrument, control with protecting the control such as component, monitoring assembly, various AC circuit breakers
Component, is controlled to circuit, protects, measures, measures, monitors.
Medium Voltage Switchgear can run down with the growth of use time, the running status of switch cubicle, the various failure symptom of a trends
Can progressively it show；Mechanical breakdown, insulation fault, heating accident, burst accident are major failure and the accident source of Medium Voltage Switchgear；
Because natural cause (thunderbolt, condensation), the manufacturing defect of equipment, the mistake of design and installation, repair quality are unqualified or operation
Short circuit or irregular operating state, may all cause accident in power system caused by maintenance is improper.Failure once occurs,
It must rapidly and selectively cut off fault element.Medium Voltage Switchgear itself is there is also potential safety hazard, and Medium Voltage Switchgear is in fortune
Cabinet door is closing all the time during row, and operations staff can not know main electrical scheme state in cabinet, various components in switch cubicle
Actual working state can not be found out；It is easy to cause power grid accident when breaking down due to Medium Voltage Switchgear and causes great warp
Ji loss, widely used maintenance mode is periodic inspection in the prior art and overhauls afterwards, the discovery that maintenance can not be early afterwards
The failure and defect of equipment；Periodic inspection lack of targeted, it is impossible to which pre- protrusion-dispelling also tends to cause man power and material's with accident
Significant wastage, simultaneously because excessive maintenance is also possible to bring new potential safety hazard.
The intellectuality of Medium Voltage Switchgear is related to measurement digitlization, control networking, status visualization, information interaction etc.
Many-sided intellectualized technology, Intelligent medium-voltage switch cabinet is used as most important control element in power system, its automation and intelligence
Energyization is the intelligentized basis of grid equipment.And the intellectuality of Medium Voltage Switchgear is intellectuality and the switch cubicle of breaker first
It is intelligent；Shortcoming and deficiency of the prior art are that insulating element condensation problem accounts for sizable ratio in insulation fault, absolutely
The filth of edge part causes insulating properties to reduce, the understanding that equipment state and life-span can not be promptly and accurately, it has to need power pipe
Reason person carries out artificial timing to scene and overhauled, and some potential faults can't be found that this is also to perplex electric power for many years in time
The problem of safety in production；Detected in the prior art usually using leakage current, but when leakage current occurs for insulating element, absolutely
The insulating properties of edge part have produced irreversible change, it is impossible in dew condensation phenomenon of the early stage to insulating element, pollution degree
Contamination phenomenon is detected, detects and prevented；Chassis vehicle of the prior art is in the process of running, it may appear that mechanicalness or electrical resistance
Refuse to block up, it is impossible to perform operation, the status information of correlation can not be captured when particularly refusing stifled again, once generation will be to power transmission and transformation
System brings about great losses；Real-time control, monitoring, diagnosis are carried out to Medium Voltage Switchgear；Insulating element condensation, pollution carry out early stage
Inspection, and can find that chassis vehicle refuses the assurance measures of stifled situation, the intelligent medium voltage switchgear of corresponding function is developed, and incorporate
Into whole power network, it is ensured that generating, transmission of electricity, distribution, the overall grid operation safety of electricity consumption.
