Description
(1), technical field
The present invention relates to a kind of sealed type outdoor high-tension phase control synchronous permanent magnetic structure vacuum circuit-breaker; be applicable to industrial and mining enterprises, power plant and electric substation's control and protection rated frequency 50Hz; the three-phase alternating current electric capacity load of rated voltage 12kV, 40.5kV, 126kV electric pressure and the usefulness of inductive load are particularly useful for opening-closing capacitor bank, transformer, reactor and other need the occasion of frequent operation.
(2), background technology
At present, the outdoor vacuum circuit breaker of domestic 12kV and above electric pressure adopts the spring energy-storage operating mechanism more, and invests outside the breaker body.Because its mechanism's complexity, middle transmission link is many, in addition can not integral sealing, and make and adhere to dirt or the serious operating mechanism of corrosion easily produces misoperation or " getting stuck " malfunctioning phenomenon, influence normal power supply.A major issue of primary cut-out is exactly when suiting inductive or capacity load, transient voltage can occur and shoves more greatly.This is not only unfavorable to the insulation system of power equipment, can cause that also protective device produces misoperation, influences the stability of electric power system.
(3), summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of sealed type outdoor high-tension phase control synchronous permanent magnetic structure vacuum circuit-breaker, it can implement synchronous break-make, shoving and overvoltage when avoiding producing operation, shorten the transient process of electric power system, improve the stability of the quality of power supply and electric power system.
The present invention solves the technical scheme that its technical problem takes: three insulation crusts are fixed in the upper end of pedestal, the structure of three insulation crust inside is identical, lower end in the insulation crust is permanent magnet mechanism fixedly, one end of the power output shaft of permanent magnet mechanism connects the high strength insulated tension pole, the other end of insulated tension pole is hinged on the movable feeler lever of vacuum interrupter, movable feeler lever is fixed on lower wire end by being flexible coupling, vacuum interrupter is fixed on the upper end in the insulation crust, and the fixed contact of vacuum interrupter fixedly is electrically connected with last end of incoming cables lid; The lower end fixed support of pedestal, fixing control cabinet on the support is equipped with PLC, CPU single-chip microcomputer, electric current, voltage-phase detector and control circuit in the control cabinet, and control circuit is electrically connected with the coil of described permanent magnet mechanism.
Vacuum interrupter and permanent-magnet operating mechanism are coupled as one, encapsulate with solid insulating material, can implement synchronous break-make, this circuit breaker is compact conformation, reliable not only, the deduction and exemption maintenance, and can be at load of different nature, detect the voltage/current phase angle of every phase, adopt PLC and CPV monolithic processor control device, make switch, implement separating brake, combined floodgate the paying good branch most, close the phase angle of predetermined load characteristic.Shoving and overvoltage when this just can be avoided producing operation, the transient process of shortening electric power system improves the stability of the quality of power supply and electric power system.
(4), description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a front view of the present invention;
Fig. 2 attempts for a left side of the present invention.
(5), embodiment
As shown in Figure 1, 2, the upper end of pedestal 1 structure of fixing 2, three insulation crust 2 inside of three insulation crusts by upper and lower flange 14,15 is identical.Lower end in every insulation crust 2 is permanent magnet mechanism 5 fixedly, the upper end of the power output shaft 6 of permanent magnet mechanism 5 connects high strength insulated tension pole 7, the upper end of insulated tension pole 7 is hinged on the movable feeler lever 10 of vacuum interrupter 11, and movable feeler lever 10 9 is fixed on lower wire end 8 by being flexible coupling.Vacuum interrupter 11 is fixed on the upper end in the insulation crust 2, and the fixed contact 12 of vacuum interrupter 11 fixedly is electrically connected with last end of incoming cables lid 13.The lower end of described each permanent magnet mechanism 5 is stretched into pedestal 1 and is connected with manual emergency switching-off device 16, and a manual brake separating bar 4 and three divide-shut brake pointers 3 are arranged on the manual emergency switching-off device 16.Under the state of emergency, pull manual brake separating bar 4, control three phase mains can be cut off simultaneously.The lower end fixed support 18 of pedestal 1, fixing control cabinet 17 on the support 18 is equipped with PLC, CPU single-chip microcomputer, electric current, voltage-phase detector and control circuit in the control cabinet 17, and control circuit is electrically connected with the coil of described permanent magnet mechanism.
The material of described insulation crust 2 is resin compounded silicon rubber or high-strength ceramic, and 9 the material of being flexible coupling is silver-plated red copper foil.
