Description
Technical field
The utility model relates to a kind of electric protection device, relates in particular to a kind of electronic mutual inductor high-tension switch cabinet.
Background technology
Along with the develop rapidly of computer technology, electric power system is intelligent to measurement, protection, control and communication device, the requirement of automation is more and more higher, for power system security, requirement reliable and the high-quality operation, is also improving constantly.For this reason, parent company of State Grid proposes especially: the function of measurement, supervision, protection, control, safe related function operation being combined, form " electromechanical integration " new ideas power equipment, is electric equipment development trend from now on.Therefore realize networking, the digitlization of electric power system, the intellectuality of power equipment, miniaturization, modularization, multifunction, become the main flow that domestic and international famous power equipment manufacturing enterprise carries out research and development of products.
The digital development of power equipment electrical secondary system measuring instrument and protective device, the intelligent substation of being managed concentratedly with digitalized network is widely used in electric power system.
High-tension switch cabinet is as a kind of important protective device; most adopts traditional current-voltage transformer, and traditional current-voltage transformer is induction, is wound with first and second winding on iron core; by electromagnetic coupled, the magnitude of current is passed to secondary side from primary side.Complicated insulation system is being arranged, to guarantee the electrical isolation of high and low pressure equipment between iron core and winding and between first and second winding.The advantages such as it is simple in structure, operate steadily, manufacturing process maturation have been generally acknowledged by industry, but have also been had following inherent defect:
1) insulation system complexity, the large cost of volume is high.With the raising of electric pressure, its cost also is exponential raising.
2) core structure inevitably can produce ferromagnetic vibration, and to equipment and system, operation brings harm.
3) iron core has non-linearly, and magnetic hysteresis and magnetic saturation phenomenon make measuring range limited, and passband is narrow, and the instrument transformer transient performance is poor.When electric power system is short-circuited, the short circuit current of high amplitude makes instrument transformer saturated, and the secondary current of output seriously distorts, thereby protection equipment can produce malfunction or tripping, also make the novel quick protection based on the high frequency transient component be difficult to realize.
4) output does not allow open circuit operation, if open circuit produces high pressure, easily to operating personnel, brings work danger.
5) insulating oil or gas are buried inflammable and explosive hidden danger, have also improved the requirement to service work.Time between overhauls(TBO) is short, and maintenance workload is large.
6) signal imitation is exported, and is unfavorable for digitlization and the networking process of power system monitor.
7) raising of product class of accuracy grade is limited, though the product of 0.2S level is arranged at present, its cost improves a lot.
Above-mentioned inherent shortcoming due to traditional electromagnetic type current-voltage transformer, adopt the high-tension switch cabinet of this electromagnetic type current-voltage transformer also to there is corresponding defect, be difficult to computer technology and the current/voltage complete information carried out to the requirement of digitized processing, be difficult to the on-line monitoring of realizing that electrical network changes electrical parameter.Therefore in the urgent need to research and develop a kind of can with the matching used Novel high tension switchgear of digitalized network.
For researching and developing novel high-tension switch cabinet, the primary problem solved is to provide a kind of suitable high-tension switch cabinet body, but mostly the internal structure layout is unreasonable for current high-tension switch cabinet body, causes internal wiring in disorder, is difficult to the problems such as wiring, maintenance, maintenance.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of electronic mutual inductor high-tension switch cabinet, and this electronic mutual inductor high-tension switch cabinet interior layout is reasonable, makes internal wiring in good order, easily maintenance, maintenance, and improved control precision.The technical scheme adopted is as follows:
A kind of electronic mutual inductor high-tension switch cabinet, comprise cabinet, it is characterized in that: also comprise vertical clapboard, the first diaphragm plate, the second diaphragm plate and the 3rd diaphragm plate; Vertical clapboard is divided into front chamber and rear chamber by described cabinet; The first diaphragm plate is located in front chamber, and the first diaphragm plate is divided into relay bungalow and handcart chamber from top to bottom by front chamber; The second diaphragm plate, the 3rd diaphragm plate are located in rear chamber, and the second diaphragm plate, the 3rd diaphragm plate are divided into main bus bar chamber, electronic mutual inductor chamber and cable vault from top to bottom by rear chamber.
By vertical clapboard, the first diaphragm plate, the second diaphragm plate and the 3rd diaphragm plate, cabinet is divided into to a plurality of independently functional compartments: relay bungalow, handcart chamber, main bus bar chamber, electronic mutual inductor chamber and cable vault, layer of structure is clearly demarcated, layout is quite reasonable, being suitable for modularization arranges, installs, manages, make internal wiring in good order, easily maintenance, maintenance; Particularly be provided with independently electronic mutual inductor chamber, electronic current voltage instrument transformer and complicated cable separating are come, avoid the electronic current voltage instrument transformer to be subject to the interference of cable, improved control precision.
