Abstract
The utility model relates to a combined electric appliance of a novel high-voltage circuit breaker-an isolating switch. The utility model is composed of an arc extinguish chamber, an upper and a lower isolating contacts, a drive mechanism and an insulating part. The isolating contacts and the breaker are assembled together, and a new independent element-a combined electric appliance is formed. The combined electric appliance and the traditional isolating switches (generally two) are installed at both sides of in-out lines of the breaker. Compared with the connection mode of the conductor and the breaker, the occupation volume is decreased by more than 50 %, and the cost is greatly reduced. In addition, the isolating contacts adopt a telescopic structure, and compared with a rotary type structure, the spaces of the left and the right sides are reduced by more than 30 %.
Description
Technical field
The utility model relates to the High-Voltage Electrical Appliances field, particularly a kind of novel high-voltage circuit-breaker-isolating switch combined electrical apparatus.
Background technology
The supporting method of present widely used circuit breaker and isolating switch has two kinds:
(1), circuit breaker two independently isolating switches are installed respectively into and out of the line both sides, connect with lead again; Constitute a power supply (being subjected to) unit.The method is fairly simple, but it is big to take up room, and is used in the equipment of complete switch of 12KV grade more.
(2), be fixed in the upper and lower outlet of circuit breaker, circuit breaker and operating mechanism thereof and moving contact move forward and backward simultaneously, make it and isolate fixed contact to be switched on or switched off isolating moving contact.Reduce to some extent though the method takies volume than (1) kind method, because the whole distance that moves big (this problem of 40.5KV grade is more serious), totally take up room or bigger.In addition, because be to move together with circuit breaker and operating mechanism thereof, weight is very heavy, complicated operation manufacturing cost height.The method is used in the portable switchgear more.
The utility model content
The purpose of this utility model is: a kind of novel high-voltage circuit-breaker-isolating switch combined electrical apparatus is provided, reduces taking volume, reduce the weight of functional unit, reduce cost and easy to use.
The purpose of this utility model is achieved in that a kind of novel high-voltage circuit-breaker-isolating switch combined electrical apparatus, is by arc control device, upper and lower insulating contact, and transmission mechanism and insulating part are formed; It is characterized in that: (a), isolate moving contact and be installed in the upper and lower outlet of circuit breaker; (b), to isolate moving contact be upper and lower stretching motion, is retracted into during withdrawal in the inner chamber of an insulator, this insulator is again simultaneously the connector between the upper and lower outlet of circuit breaker; (c), is connected by the awl tooth between isolation switch shaft and the insulation axle, the insulation axle connects by worm and wheel, and turbine connects with gear by gear shaft, to conducting rod (isolation moving contact), makes its rectilinear motion in the transmission of process tooth bar.The kind of drive of the penultimate stage of-described transmission mechanism is the worm and gear transmission, plays non-return effect.The afterbody of-described transmission mechanism adopts the rack-and-pinion kind of drive, the rotation motion motion that is in line.
Because above-mentioned structure is arranged, make the utility model reduce and take volume, reduce the weight of functional unit, reduce cost and easy to use.

Fig. 1 is the front view of the utility model structure;
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure, the last isolation switch shaft of 1-; 2-main cone tooth; The secondary awl of 3-tooth; 4-insulate the axle; The 5-insulator; The 6-upper bracket; The 7-worm screw; The 8-fixed contact; The 9-fingertip; The 10-extension spring; The last conducting rod of 11-; The 12-worm gear; The 13-gear; The 14-tooth bar; 15-fingertip (interior fingertip); 16-extension spring (interior fingertip is used); The 17-insulating cylinder; The 18-vacuum interrupter; The 19-insulating support; 20-conducts electricity fixture block; 21-is flexible coupling; The 22-lower carriage; Conducting rod under the 23-; The 24-fairlead; Fixed contact under the 25-; The 26-swing screw; The 27-connecting lever; The 28-insulated tension pole; The 29-supporting leg; The 30-spin; The 31-main shaft; The 32-sluice separating spring; The 33-base; The 34-worm-wheel shaft; 35-top guide bar chamber; 36-lower guide rod chamber.
Embodiment
Referring to Fig. 1, Fig. 2; The course of work of circuit breaker is as follows: ((being installed on the main shaft (31)) comes rotating spindle (31) to operating mechanism by pull bar and connecting lever, by insulated tension pole (28) connecting lever (27) is rotated counterclockwise around axle, promote the arc control device moving contact by swing screw (26) at last and move upward, make breaker closing.Simultaneously, main shaft (31) spurs sluice separating spring (32) elongation, energy storage when clockwise rotating.The contact that closes a floodgate contact back operating mechanism continues motion, makes the contact stage clip compression on the insulated tension pole, makes moving contact keep certain pressure.Last operating mechanism is locked in closing position.During separating brake, the operating mechanism release that unlocks, main shaft (31) rotates counterclockwise under the effect of sluice separating spring (32), drives the arc control device moving contact at last and moves downward breaker open operation.
The formation of galvanic circle: electric current passes through fingertip (9) to conducting rod (11) by upper static contact (8).Because fingertip has been tied four extension springs (10) outward, guaranteed the pressure between fingertip and the dynamic/static contact, guarantee to move, heat-stable current passes through, a plurality of fingertips are supported by inside support ring when dynamic and static contact separates simultaneously, guarantee that fixed contact is more laborsaving during slotting tool once more.Electric current passes through fingertip (15) to upper bracket (6) by top guide bar (11).The operation principle of fingertip is same as described above, and just during the upper and lower motion of top guide bar, the tooth bar of fixing on it passes between two fingertips, and the pressure of fingertip does not change yet.Electric current arrives moving contact again by the fixed contact of upper bracket (6) to vacuum interrupter (18), arrives lower carriage (22) by conduction fixture block (20), be flexible coupling (21) again.Electric current is passing through fingertip (15) to lower guide rod (23) by lower carriage (22), and lower guide rod (23) arrives fixed contact (25) down by fingertip (9) again.
The course of work of isolating switch: go up isolation axle (1) and rotate the back by the secondary awl of main cone tooth (2) (one of every phase) drive tooth (3), secondary awl tooth (3) drives the axle (4) that insulate again and rotates.The worm screw (7) that insulation axle (4) is gone up interlock drives worm gear (12) again and rotates, and the gear (13) that turbine wheel shaft (34) is gone up interlock drives tooth bar (14) at last and guide rod (11) is upper and lower moves.The course of action of following isolation and the course of action of last isolation are identical.
