Refer to Fig. 1, the intelligent all insulation looped network switch apparatus that the utility model provides, comprises low voltage control chamber, cable vault and mechanism's installation room; The indoor intelligent protection device 13 that is provided with shove control unit 12 and the switch malfunction dropout that can prevent from being caused by surge of low voltage control; In cable vault, be provided with the current transformer 11 that can gather, monitor turnover circuit cable three-phase current data message; Breaker operation mechanism 14 is housed in mechanism's installation room; Current transformer 11 is electrically connected with shove control unit 12 and intelligent protection device 13 respectively, and the control unit 12 that shoves is electrically connected with intelligent protection device 13, and intelligent protection device 13 is connected with breaker operation mechanism 14.
Compared to prior art; the intelligent all insulation looped network switch apparatus that the utility model provides; current transformer 11 is monitored the three-phase current data message of electrical network 15; and these information are sent to the control unit 12 that shoves; the control unit 12 that shoves will send to information intelligent protection device 13 again after these information processings; intelligent protection device 13, according to the information of uploading, is controlled breaker operation mechanism 14, thereby reaches the operation of automation control monitoring intelligent type loop-network switch cabinet.The utility model forms energy automatic monitored control system, at any time monitoring intelligent type loop-network switch cabinet whole system running status by current transformer 11, the control unit 12 that shoves, intelligent protection device 13 and breaker operation mechanism 14; Reduce a large amount of human and material resources and drop into, improve equipment safety operation reliability.
In the present embodiment, isolating switch and earthing switch operating mechanism are housed in mechanism's installation room, and mechanical interlock mechanism; Isolating switch and earthing switch operating mechanism are by mechanical interlock mechanism and breaker operation mechanism 14 mechanical connections.Due to the interlocking device of intelligent all insulation looped network switch apparatus be a kind of structure-integrated, force the interlock of interlock, have advantages of simple and quickly, can effectively avoid operate miss, its operating process only needs strictly to operate in operation sequence.
In the present embodiment, intelligent protection device 13 is provided with communication module 131, and communication module 131 is connected with electrical network 15 control centres 16 communications.Intelligent protection device 13 carries out communication contact by communication module 131 with electrical network 15 control centres 16; on the one hand the electrical network of monitoring 15 information are sent to control centre 16 by intelligent protection device 13, and control centre 16 sends instruction directs intelligent protection device 13 and works on the other hand.Intelligent protection device 13 can be the communications such as radio communication or optical fiber with the communication connected mode of control centre 16.
Communication module 131 makes the utlity model has remote-operated function, in the time that accident occurs, enter execute-in-place on the spot without staff, can carry out the operation of long-range strange land in control centre 16, the labour intensity and the work that greatly reduce electric power system employee are dangerous, improve troubleshooting efficiency, can fix a breakdown in time, loss has been dropped to minimum.
In the present embodiment, this switchgear also comprises power-supply system, and power-supply system is connected with communication module 131, intelligent protection device 13 and breaker operation mechanism 14 respectively.Be provided with independently power-supply system, ensure in the time there is fault, the work that intelligent all insulation looped network switch apparatus still can be normally stable.
The intelligent all insulation looped network switch apparatus that the utility model provides, not only has that mechanical strength is high, dependable performance, long service life, easy and simple to handle a, advantage such as flexibly; Have long-range, straighforward operation, the absorption function such as shove, be safe, desirable, the reliable auxiliary products of department of State Grid urban distribution network automation simultaneously.This Intellectualized Switchgear performance meets the requirement of the standards such as GB984 " ac hv breaker " GB3906 and this product " technical conditions ", and its leading indicator meets or exceeds 〝 IEC 〞 standard.
The intelligent all insulation looped network switch apparatus that the utility model provides, can carry out quick-break, time delay, phase overcurrent protection, zero sequence excess current protection and external ground, the feature operations such as switch divides, combined floodgate by control centre 16.In ring network structure line powering region, city, realize automatic diagnosis fault, the automatic separating fault section of distribution and the power supply that automatically recovers non-faulty section.Intelligent all insulation looped network switch apparatus also possesses segmented model and contact pattern.Segmented model has: time-delay closing, the functions such as dead electricity separating brake and closing locking.Contact pattern has: time-delay closing, and time limit locking, pulse locking, electric locking is carried out in both sides, and a side carrys out electric locking and locking automatically terminates function.In the time breaking down in certain region, can be in time by the switch separating brake power-off in its this region of disjunction, isolated fault region, subsequently the non-fault zone because of line failure dead electricity is restored electricity rapidly, thereby avoid causing the continuous dead electricity of whole piece circuit because circuit breaks down, greatly reduce power failure range, improved the security reliability of power supply quality.
Show according to power department reliability data, affect at present power supply reliability be mainly customary detection time power distribution network 15 have a power failure, this one-phase interruption duration is much larger than the power failure causing due to power distribution network 15 faults.In the time that system breaks down, be through cooperatively interacting between the secondary relay protection devices such as circuit breaker, excise fast fault, do not need computer get involved control in real time, at this moment between section in use equipment be mainly second protection control appliance.But, being subject to the impact of power supply and relay equipment, automaticity is very low.In this time period, when system is normally moved, running status that can not real-time detection system, is only in the time that system breaks down, its effect of linear quadratic control protection equipment competence exertion; If after the operational mode of system changes, need staff's calculating of again adjusting to scene; Could recover incident area power supply; Can not automatically take optimization measure; In the accident recovery stage, need to adopt multiple shot reclosing, to ensure the normal operation of system, still, this method is very large to intrasystem switchgear damage.The intelligent all insulation looped network switch apparatus that utilizes the utility model to provide, can improve distribution automation management, greatly reduces customary interruption duration and the number of times detecting.
Disclosed is above only several specific embodiment of the present utility model, but the utility model is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection range of the present utility model.
