Description
Technical field
The present invention relates to high voltage electric equipment device technology field, relate in particular to a kind of novel indoor high-voltage vacuum on-load switch-high-tension fuse combined electrical apparatus.
Background technology
As everyone knows, indoor high-voltage vacuum on-load switch-fuse combined electric apparatus is a kind of high-voltage switch electric appliance generally using, but is used for greatly the Simple switch of 10kV electric pressure, and this type of switch of 40.5kV electric pressure is relatively less.
The total arrangement of existing 40.5kV Voltage Class electrical equipment is divided into two classes substantially, one class is monolateral layout, (seeing Fig. 1 and Fig. 2) is the side that all functions parts and operating mechanism are arranged in frame, this class combined electrical apparatus is relatively simple for structure, but volume is larger, transportation and installation are inconvenient, are mainly move and operate very inconvenient, the in the situation that of can not be charged in high-pressure side, change the fuse burning.Use is very limited.The bilateral layout of another kind of routine, (seeing Fig. 3 and Fig. 4) isolating switch and on-load switch, fuse is arranged in the both sides of frame, use more convenient, performance also can, still, the one, volume is large, poor reliability.The 2nd, can not meet the requirement of " five is anti-".
These two kinds of combined electrical apparatuses, have a common problem, are exactly that isolating switch and earthed switch link, can not operate respectively, can only meet the operation of normal operating condition, can not be when breaking down, the personal safety of assurance equipment, there is certain defect, can not meet the requirement of " five is anti-" completely, due to the restriction of volume, this two classes combined electrical apparatus is at insulation distance, voltage withstand class aspect, selects all smallerly, and the scope of application is restricted.
For operating mechanism: existing combined electrical apparatus is mainly manual operation, have some can be manually and electric operating, but operating mechanism be fairly simple, poor reliability, performance is stable not.With respect to wind power plant, be located in remotely, vast in territory, take remote control operation as main technical requirement, existing combined electrical apparatus, uses quite inadequate.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of stable performance, indoor high-voltage vacuum on-load switch-fuse combined electric apparatus applied widely, comprise frame, isolating switch, fuse and vacuum load switch, it is characterized in that described isolating switch and fuse are arranged in the both sides of frame, vacuum load switch is arranged in the top of frame, three parts are triangularly arranged, in described frame, be also provided with operating mechanism, described operating mechanism below is provided with five-proof program lock, described frame both sides are provided with electrified sensor, the electrified sensor that is positioned at fuse one side is connected with fuse lower end, the vacuum-load pipe that described vacuum load switch is installed by insulator and the level of angle mount forms, described vacuum-load pipe one end is connected with insulator by fixed contact box, the vacuum-load pipe other end is connected with insulator by moving contact box, described moving contact box below is provided with insulated tension pole, described moving contact box, two guiders have been adopted, the guide bearing of the connection vacuum-load pipe of described vacuum load switch keeps horizontal movement, on described guide bearing, be provided with directive slide track, described directive slide track is connected with insulated tension pole by jockey.
Beneficial effect of the present invention is: isolating switch and earthed switch, fuse is arranged in the both sides of frame, vacuum load switch is arranged in the top of frame, three parts are triangularly arranged, such layout has effectively reduced the volume of box type transformer, reduced manufacturing cost, main transportation of giving box type transformer, installation provides great convenience, the moving contact box of vacuum load switch, two guiders have been adopted, the guide connecting rod that connects vacuum-load pipe keeps horizontal movement, solved the technical problem that vacuum-load pipe level is installed, guaranteed the performance and used life of vacuum load switch.
Due to leg-of-mutton layout, can there be enough spaces to arrange electric equipment element, obtain maximum insulation distance.Actual measurement minimum insulation distance is greater than 360 millimeters, and 300 millimeters and 340 millimeters of common combined electrical apparatuses.Insulation distance is large, and the scope of application of combined electrical apparatus has been expanded, general design, and the scope of application is at height above sea level below 1000 meters, and the scope of application of this practicality is at height above sea level below 2500 meters.
Due to the leg-of-mutton layout of the present invention, isolating switch and fuse be in the both sides of frame, the in the situation that of charged in high-pressure side, as long as pull open isolating switch, and the fuse that replacing that just can safety is burnt, very easy to use, practicality.
The operating mechanism of general on-load switch is the mounting means of clamping plate type, and the performance of mechanism is stable not, the poor reliability of operation some.Operating mechanism of the present invention, employing be the brand new of frame-type, Stability Analysis of Structures, dependable performance, field adjustable is simple, can realize the life-cycle non-maintaining.Operating mechanism can on-the-spot electric operating, manual operation.Particularly be applicable to remote operation, while operating in the distance, the service position of indication mechanism exactly, state, can carry out energy storage, closes a floodgate, separating brake, operation.Be specially adapted to wind power plant scarcely populated, region is remote, take remote operation, as main place, uses, and in control room, to the status of equipment of whole wind energy turbine set, controls comprehensively.
