Abstract
The utility model discloses high stability switchgears, with cabinet body, static contact and moving contact are equipped in the inside of the cabinet body, it is characterized by: the moving contact is connected in shaft, rotating with shaft drives moving contact to contact or separate with static contact, and one end of the shaft is rotatably connected in support plate, is actively equipped with sliding sleeve in the support plate, one end of the sliding sleeve is fixedly connected with the inner wall of cabinet body, and the other end of the shaft is connect with operating mechanism.The utility model structure is simple, rationally, after interior of the cabinet is filled with high-voltage isulation gas, shaft will not shift with the external drum of inner wall for design, and then guarantee the stability of moving contact position, it is ensured that moving contact, which can be contacted successfully with static contact, completes combined floodgate operation.
Description
Technical field
The utility model relates to electrical equipments, and in particular to a kind of high stability switchgear.
Background technique
The main function of switchgear be generated electricity in electric system, transmitted electricity, the conversion of distribution and electric energy during, carry out
Folding, control and protection electrical equipment.The interior of the cabinet of switchgear is provided with moving contact and static contact, moving contact, which is connected to, to be turned
On axis, support base is fixedly connected on the inner wall of cabinet body, shaft is rotatably arranged on support base, and is controlled by operating mechanism
Shaft rotates and then drives moving contact and static contact carries out division, and then realizes separating brake and close a floodgate.Wherein, in order to avoid dynamic and static
Electric arc, electric spark that contact is generated due to high pressure etc. influence the stability of disconnecting switch gate-dividing state, generally require in cabinet body
Inside is filled with the inert gas (such as sulfur hexafluoride) of high-insulativity, increases the insulating properties of interior of the cabinet with this, and then guarantees to divide
The stability of lock state, but find in actual use, since the inert gas pressure being filled with is very big, cabinet body can be made
Inner wall slight external drum occurs, cause support base to shift, being inconjunction with moving contact in shaft and shaft can also occur partially
It moves, and then influences going on smoothly for combined floodgate operation.
Summary of the invention
In view of the deficiency of background technique, the technical problem to be solved by the utility model is to provide a kind of structure is simple, if
Rationally, after interior of the cabinet is filled with high-voltage isulation gas, shaft will not shift meter with the external drum of inner wall, and then guarantee
The stability of moving contact position, it is ensured that moving contact can successfully contact the high stability switch for completing combined floodgate operation with static contact
Cabinet.
For this purpose, the utility model is realized using following scheme:
High stability switchgear has cabinet body, is equipped with static contact and moving contact in the inside of the cabinet body, feature exists
In: the moving contact is connected in shaft, rotates with shaft and moving contact is driven to contact or separate with static contact, and the one of the shaft
End is rotatably connected in support plate, and sliding sleeve, one end of the sliding sleeve and cabinet are actively equipped in the support plate
The inner wall of body is fixedly connected, and the other end of the shaft is connect with operating mechanism.
The support plate is in ground connection setting.
The inner wall of the cabinet body is equipped with rear cross beam, and the sliding sleeve is fixedly connected with rear cross beam.
By adopting the above technical scheme, the advantages of the utility model are as follows: 1, simple structure and reasonable design can be realized scale
Metaplasia produces；2, shaft is rotatably connected in support plate, and is movably equipped with sliding sleeve in support plate and is mentioned to support plate
For support, one end of sliding sleeve is fixedly connected with the inner wall of cabinet body, when cabinet body inner wall due to interior of the cabinet High Voltage inertia
The influence of gas and when external drum occurs, can be moved together with sliding sleeve, since sliding sleeve is that activity is fed through support plate, therefore
And sliding sleeve will not be moved together with support plate and can still provide support plate support, so that the position of support plate will not
It shifts, and then ensures the stability of moving contact position, guarantee that moving contact can successfully contact completion with static contact and close a floodgate
Operation.
Detailed description of the invention
The utility model has following attached drawing:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the partial enlarged view in Fig. 1 at A direction.
Specific embodiment
As shown, high stability switchgear disclosed by the utility model, has cabinet body 9, it is equipped in the inside of cabinet body 9 quiet
Contact 2 and moving contact 3, moving contact 3 are connected in shaft 4, rotate with shaft 4 and moving contact 3 is driven to contact or divide with static contact 2
From one end of shaft 4 is rotatably connected in support plate 5, and the other end is connect with operating mechanism 1, is actively worn in support plate 5
Equipped with sliding sleeve 6, support is provided to support plate 5, one end of sliding sleeve 6 passes through the rear cross beam 7 on fastener and 9 inner wall 8 of cabinet body
Connection, the rear cross beam 7 can be integrally formed with cabinet body 9, be also possible to be connected to cabinet body 9 by the modes such as welding, clamping
Inner wall on, by be arranged rear cross beam 7, the connection of sliding sleeve 6 Yu 9 inner wall 8 of cabinet body can be easily facilitated.When in cabinet body 9
Wall 8 due to the strong inert gas of 9 internal high pressure of cabinet body influence and when external drum occurs, can be moved together with sliding sleeve 6, due to
Sliding sleeve 6 is that activity is fed through support plate 5, so sliding sleeve 6 will not move together with support plate 5 and still can be to branch
Fagging 5 provides support, so that the position of support plate 5 will not shift, and then ensure the stability of 3 position of moving contact, guarantees
Moving contact 3, which can be contacted successfully with static contact 2, completes combined floodgate operation.In addition, support plate 5 is further promoted in ground connection setting
5 self stability of support plate.
