Abstract
A combined electrical appliance with a novel rotary three-position switch mainly comprises a shell, an arc extinguishing chamber, and an isolation switch static contact arranged in the shell. A static contact of a grounding switch is arranged at the side opposite to the isolation switch static contact. The circuit breaker arc extinguishing chamber is fixedly arranged at one end inside the shell. The circuit breaker arc extinguishing chamber and a three-position switch are arranged separately, and the three-position switch is arranged inside the shell and is in assembly connection with the circuit breaker arc extinguishing chamber, so that the circuit breaker arc extinguishing chamber and the three-position switch are integrated in the shell to form an integral unit. According to the invention, because the circuit breaker arc extinguishing chamber and the three-position switch are integrated in the shell to form an integral unit, the impact of the action of the arc extinguishing chamber to the three-position switch is avoided, the structure of the three-position switch is simplified, the operability of the switch is increased, the size and weight of the switch are reduced, the overall structure of the combined electrical appliance is more compact, and the work safety coefficient is improved.

Technical field
The present invention relates to the high-voltage switch equipment used in electric power system, be specially the compound combined electrical equipment of 145kV electric pressure.
Background technology
Compound combined electrical equipment is the capital equipment in high-tension power transmission and transformation equipment, at present, and the isolation in the compound combined electrical equipment of 145kV electric pressure and earthed switch many employings three station structure.So-called three stations refer to three service positions: the closing position that 1 isolated switch main fracture is connected, the isolated location that 2 main fractures separate, the earthing position of 3 ground side.Three-station is exactly the function incorporating isolating switch and earthed switch in fact, so just can realize mechanical latching, prevents major loop charged conjunction ground cutter.
In prior art, three-station separate unit often in compound combined electrical equipment, itself and major part circuit breaker are arranged apart, due to structural reason, add quality and the volume of product, Total Product height is increased, and circulation poor stability, touch base rotate dumb, and dynamic and static contact impacts larger when closing a floodgate, action stability is poor, bring difficulty to operator, its Corrosion Protection arranged apart is poor, and useful life is short.
Summary of the invention
The present invention is directed to the problems referred to above, devise a kind of combined electrical apparatus with New Rotary three-station, its object is to: make the structure of combined electrical apparatus simpler, alleviate volume of switch weight, improve coefficient of safety during switch.
A kind of combined electrical apparatus with New Rotary three-station, mainly comprise: housing, arc control device, the isolating switch be located in housing quiet side contact, the quiet side contact of earthed switch is provided with at isolating switch quiet side contact opposite side, arc-extinguishing chamber of circuit breaker is fixed with in enclosure interior one end, described arc-extinguishing chamber of circuit breaker and three-station arranged apart, it is characterized in that: described three-station is located at enclosure interior and arc-extinguishing chamber of circuit breaker assembly connection, arc-extinguishing chamber of circuit breaker and three-station are merged in housing, forms an integral unit.
Described three-station is located at enclosure interior and is set on arc-extinguishing chamber of circuit breaker.
Described three-station comprises: be located in the axis hole of housing the other end be connected with drive unit operating axis, to be fixedly connected with operating axis and the three station unit rotated along with operating axis, described three station unit move in the contact groove of side and are provided with spring touch finger with the quiet side contact opposite side of isolating switch quiet side contact and earthed switch, spring touch finger rotates in groove corresponding to the quiet side contact of isolating switch quiet side contact, earthed switch successively with operating axis, realizes tri-station isolating switch respectively and closes a floodgate and three station grounding switchs combined floodgate.
Described three station unit two ends are connected with housing by rolling bearing, realize rotating.
Beneficial effect of the present invention:
The present invention is by merging arc-extinguishing chamber of circuit breaker and three-station in same housing, form an integral unit, avoid the impact of action to three-station of arc control device, simplify three-station structure, increase the operability of switch, alleviate volume of switch weight, make whole combined electrical apparatus structure more compact, improve coefficient of safety during work.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described further:
A kind of combined electrical apparatus with New Rotary three-station as shown in Fig. 1 to 5, mainly comprise: housing 1, be located at the isolating switch quiet side contact 3 in housing 1, the quiet side contact 2 of earthed switch is provided with at isolating switch quiet side contact 3 opposite side, arc-extinguishing chamber of circuit breaker 5 is fixed with in the inner one end of housing 1, described arc-extinguishing chamber of circuit breaker 5 is arranged apart with three-station 4, it is characterized in that: described three-station 4 is located at housing 1 inside and arc-extinguishing chamber of circuit breaker 5 assembly connection, arc-extinguishing chamber of circuit breaker 5 and three-station 4 is made to merge in housing 1, form a merge cells.Described three-station 4 comprises: be located at the operating axis 4-1 be connected with power set in the axis hole of housing 1 the other end, be fixedly connected with operating axis 4-1 and the three station unit 4-2 rotated along with operating axis, described three station unit move in the contact 4-5 groove of side and are provided with spring touch finger 4-3 with quiet side contact 2 opposite side of isolating switch quiet side contact 3 and earthed switch, spring touch finger 4-3 rotates to isolating switch quiet side contact 3 with operating axis 4-1 successively, in groove corresponding on the quiet side contact 2 of earthed switch, realize tri-station isolating switch respectively to close a floodgate and three station grounding switchs combined floodgate.
Specific works process:
Drive unit drives operating axis to rotate, and makes whole three station finite element rotations, and three station unit move side contact and also and then rotate, and when three stations move side contact to the sideway swivel of isolation fixed contact, and contacts completely, realizes tri-station isolating switch and close a floodgate (as shown in Figure 3); When three stations move side contact to grounding static contact sideway swivel, drive its upper spring fingertip to rotate completely in groove corresponding to the quiet side contact of earthed switch, realize three station grounding switchs and close a floodgate (as shown in Figure 4).Three station unit move side contact and also can rotate to and neither make isolating switch close a floodgate the state (as shown in Figure 5) also not making earthed switch close a floodgate.
Three station unit are in rotary course, and arc-extinguishing chamber of circuit breaker is failure to actuate.Dependence rolling bearing is relatively rotated between them.And the electrical contact side between them relies on two spring touch fingers, arc-extinguishing chamber of circuit breaker and three-station merge in a housing, define an integral unit.The present invention is by merging arc-extinguishing chamber of circuit breaker and three-station in same housing, form an integral unit (as shown in Figure 1), simplify three-station structure, increase the operability of switch, alleviate volume of switch weight, make whole construction of switch more compact, improve coefficient of safety during switch.
To sum up, the present invention accomplishes the end in view.
