Abstract
The utility model discloses an isolation/grounding switch applied to a metal closed switch device. The switch comprises a fixed contact which is connected with a grounding casing, a fixed contact which is connected with a bus and a moving contact which is connected with an electric connecting conductor. The two fixed contacts are located at the rotation plane of the moving contact. According to the utility model, the isolation/grounding switch can be integrated into a circuit breaker and other units, thus the switch device has a compact structure, and the space occupied by the device is significantly reduced; and at the same time, the isolation/grounding switch has the advantages of high reliability and relatively easy manufacture, thus the cost of the device is competitive.
Description
Technical field
The utility model relates to a kind of isolating/grounding switch for 40.5kV and above Cubicle Gas-Insulated Switchgear.
Background technology
Isolating/grounding switch in the Cubicle Gas-Insulated Switchgear is an independently functional unit with respect to circuit breaker in the prior art, the number that a significant shortcoming of this known types of apparatus is element is many, so that equipment takes up space and overall volume increases, increase manufacturing cost, and be unfavorable for the whole Transporting of product.
The utility model content
The utility model is for the problem in the background technology, a kind of isolating/grounding switch for metal enclosed switchgear is provided, its purpose is: can with in the prior art independently the isolating/grounding switch unit focus in the unit such as circuit breaker or bus, form the integration of functional unit.
Technical solution of the present utility model:
A kind of isolating/grounding switch for metal enclosed switchgear, it is characterized in that: described switch comprises the fixed contact that is connected with grounding shell, the fixed contact that is connected with bus and the moving contact that is connected with electric connecting conductor, and described two fixed contacts are positioned on the Plane of rotation of moving contact.
Described moving contact is fan-shaped disconnecting link contact, and it is perpendicular to the electric connecting conductor axial line.
Be connected by watchband-shaped contactor between described moving contact and the electric connecting conductor.
Described moving contact is driven by gear shaft, and the gear of this gear shaft is positioned at closure inside, and is meshed with the gear parts of disconnecting link contact.
Described moving contact is driven by gear shaft, and this gear shaft is by driver drives, and driver is arranged on the outside of closure.
Described fixed contact is provided with opening.
Rely on spring contact strip to form between described moving contact and the fixed contact and be electrically connected, spring contact strip is arranged within the fixed contact.
The beneficial effects of the utility model:
Isolating/grounding switch of the present utility model can be integrated in the unit such as circuit breaker, so that switchgear is of compact construction, reduces significantly the shared space of equipment.Simultaneously, the utility model reliability is high, makes relatively easily, so that the cost of equipment has competitiveness.

1 is radome among the figure, and 2 is electric connecting conductor, and 3 is moving contact, and 4 is watchband-shaped contactor, and 5 is baffle plate, and 6 is main contact, and 7 is shaft insulation, and 8 is pinion, and 9 is shell, and 10,11 is fixed contact, and 12 is insulating supporting.
Embodiment
Below in conjunction with accompanying drawing and be that embodiment specifically describes the utility model.
As shown in Figure 1 to Figure 3, a kind of isolating/grounding switch for metal enclosed switchgear comprises a fixed contact 10 that is connected with grounding shell 9, fixed contact that is connected with bus 11 and is connected a moving contact that is connected with electric connecting conductor 3 that described fixed contact 10,11 is positioned on the Plane of rotation of moving contact 3.Fixed contact 10,11 has an opening, and disconnecting link contact can screw in this opening.
Moving contact 3 is connected with circuit breaker electric bonding conductor 2 by watchband-shaped contactor 4, can be according to the different quantity of adjusting watchband-shaped contactor of major loop ampacity, moving contact 3 is disconnecting link contacts, by self inwall and baffle plate 5 and electric connecting conductor 2 formation positioning and guidings, guarantee can not be shifted when disconnecting link contact rotates, electric connecting conductor 2 links to each other with main contact 6, moving contact 3 has part to become the bevel gear shape, 7 is shaft insulation, be connected with pinion 8, pinion 8 is meshed with the gear parts of moving contact 3, by a driver drives shaft insulation 7 rotary actuation gears moving contact 3 is rotatablely moved, and this driver is arranged on the outside of shell 9.
Radome 1 is used for the gear of even moving contact 3 and the electric field of pinion 8, guarantees the product insulation property, and it links to each other with insulating supporting 12.
Rely on spring contact strip to form between moving contact 3 and the fixed contact 10,11 and be electrically connected, these spring contact strips are arranged within the fixed contact.
The specific works process:
As shown in Figure 3, fixed contact 10 links to each other with shell 9, when moving contact 3 rotates to fixed contact 10 position, forms the contact of earth state, and namely moving contact 3 links to each other with fixed contact 10, is not connected with fixed contact 11.
As shown in Figure 2, when moving contact 3 rotates to fixed contact 11 position, form the isolation "on" position, namely moving contact 3 links to each other with fixed contact 11, is not connected with fixed contact 10.
As shown in Figure 1, isolate the ground connection gate-dividing state when moving contact 3 rotates to isolation, ground connection centre position, namely moving contact 3 all is not connected with contact 10,11.
Except these possible structures, clearly can provide other switching manipulation according to various application requirements.
Therefore, use the driver with position controlling switch, so that the precision of moving contact opened/closed is guaranteed.
