Abstract
The utility model discloses a GIS (Gas Insulated Switchgear) air chamber connecting mechanism, comprising a pair of air chamber connecting flanges which are connected with each other through a bolt and a nut, wherein connecting holes on the air chamber connecting flanges are divided into two groups at an interval; and one group of connecting holes are arc-shaped long groove holes, and the other group of connecting holes are circular holes. According to the GIS air chamber connecting mechanism disclosed by the utility model, the independent detachment of an air chamber to be maintained can be realized, the maintenance cost is greatly reduced and the maintenance efficiency is improved; and the mechanism has the advantages of simple structure, convenience for use and operation, safety and reliability and the like.
Description
Technical field
The utility model relates to electric equipment ancillary technique field, relates in particular to a kind of GIS air chamber bindiny mechanism.
Background technique
In transformer station combined electric appliance system (GIS), normally disc insulator and two air chambers are installed by adpting flange and one group of bolt between its each air chamber and link together.The major defect of this linkage structure is, when having an air chamber to break down, air chamber to be repaired and disc insulator must be dismantled simultaneously, cause thus closing on the leakage of SF6 gas in the air chamber, then must before reinstalling, again inflate the air chamber that causes leakage, not only waste time and energy, reduce maintenance operation efficient, and the waste that brings SF6 gas resource.
The model utility content
The purpose of this utility model is the defective that overcomes prior art, and a kind of independent dismounting that can realize air chamber to be keeped in repair is provided, and reduces maintenance cost, improves the GIS air chamber bindiny mechanism of maintenance efficiency.
A kind of GIS air chamber bindiny mechanism comprises that the attachment hole interval on the described air chamber adpting flange is divided into two groups by the interconnective one pair of air chamber adpting flange of screw bolt and nut, and wherein one group of attachment hole is the arc slotted hole, and another group attachment hole is circular port.
The width of described arc slotted hole and the diameter of described circular port are isometric.
Problems of the prior art can be eliminated by GIS air chamber of the present utility model bindiny mechanism, realize the independent dismounting of air chamber to be keeped in repair, the decrease maintenance cost improve maintenance efficiency, and this mechanism has simple in structure, use the advantages such as easy to operate, safe and reliable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to Fig. 1, GIS air chamber of the present utility model bindiny mechanism, comprise by the interconnective air chamber adpting flange 1 of screw bolt and nut and air chamber adpting flange 2, attachment hole on described air chamber adpting flange 1 and the air chamber adpting flange 2 respectively interval is divided into two groups, wherein one group of attachment hole is arc slotted hole 3, and another group attachment hole is circular port 4.The diameter of the width of described arc slotted hole 3 and described circular port 4 is isometric so that after installing in the running two air chamber adpting flanges 1,2 have enough fastness that is connected with disc insulator.
GIS air chamber of the present utility model bindiny mechanism is when connection, arc slotted hole on the air chamber adpting flange 1 is corresponding with the circular port on the air chamber adpting flange 2 respectively, by bolt, nut and be clipped in 2 air chambers adpting flange 1, disc insulator in the middle of 2 links together, can put into operation.When an air chamber breaks down, the bolt, the nut that connect one group of arc slotted hole 3 on the fault gas chamber adpting flange are dismantled, insert attachment hole with the rectangular hook bolt of special arc, and use fastening nuts; Bolt, the nut that then will connect one group of circular port 4 on the fault gas chamber adpting flange are dismantled, fault gas chamber is pulled down, again the bolt on tearing open the circular port 4, nut are installed fasteningly, can in the situation that does not affect non-fault gas chamber operation, be carried out the maintenance of fault gas chamber.After the maintenance of pending fault air chamber was complete, contrary said procedure operation just can be finished abutting joint in the situation that does not affect non-fault gas chamber operation.
Claims (2)
