In some embodiments of the present invention, the cable compartment door interlocks include a first interlock 44, a second interlock 45, a third interlock 46, and a fourth interlock 47; the third interlocking member 46 is fixed to the cable chamber door, the first interlocking member 44 and the second interlocking member 45 may be inserted into the third interlocking member 46 for locking the cable chamber door, and the third interlocking member 46 may push the fourth interlocking member 47 for actuating the high voltage switch.
In some embodiments of the present invention, the mechanism chamber body unit 1 and the switch chamber are sealed by a sealing gasket;
the mechanism chamber panel 3 and the mechanism chamber body unit 1 are sealed by a sealing gasket;
the operation hole on the mechanism chamber panel is sealed by a sealing gasket.
An alternating current metal switch device comprises the mechanism chamber.
The mechanism chamber body unit 1 includes: a mechanism chamber body 11 and a rear sealing gasket 12.
The operating mechanism unit 2 includes: a switch operating mechanism 21 and a switch operating mechanism 22.
The mechanism chamber panel unit 3 includes: a mechanism chamber panel 31, a front sealing gasket 32, an operation indication hole sealing member 33.
The seal converting device unit 4 of the interlock device includes: seal transition 41, interlock seal gasket 42, interlock seal gasket bracket 43 (which may be used with the cable chamber door, described below uniformly with the cable chamber door), interlocks 44, 45, 46, 47. Of these 47 is a sheet metal part of the cable compartment door into which the sealing and switching device 41 is inserted, the interlocking parts 44, 45, 46 being structurally attached to the operating mechanism 22.
Interlocking members 44, 45, 46, 47 are provided between the operating members 21, 22 and the cable compartment door 43, see fig. 4, in order to open the cable compartment door only when safety conditions are met. The interlocking pieces 44, 45, 46, 47 all require a sealing process. The sealing conversion cover 41 and the mechanism chamber body 11 are welded together in a sealing mode, the interlocking pieces 44, 45, 46 and 47 are covered together, the opening is formed in one direction only in the front face of the switch cabinet, when the opening is installed on the cable chamber door 43, 4 edges of the opening of the sealing conversion cover 41 and the cable chamber door 43 are compressed and attached to the sealing washer 42 on the cable chamber door 43, all the interlocking pieces 44, 45, 46 and 47 extending out of the mechanism chamber are sealed, the interlocking pieces 44, 45 and 46 do not need to be sealed one by one, and the structure is few in sealing links, simple and reliable. The reference numeral 47 denotes a sheet metal structure inserted into the sealing and switching device 41 at the door of the cable compartment, and cooperates with interlocking members 44, 45, 46 housed in the sealing and switching device 41 to realize an interlocking function. The structure does not affect the interlocking function, and can simply and reliably solve the sealing problem of the interlocking piece.
The mechanism chamber body 11 is arranged on the switch chamber by using a standard fastener, and after the standard fastener is fastened, the sealing washer 12 is pressed to realize the sealing between the mechanism chamber and the switch chamber; after the mechanism chamber panel 31 and the mechanism chamber body 11 are fastened by bolts, the door edge of the mechanism chamber body 11 and the mechanism chamber panel 31 extrude the front sealing washer 32 together to realize the sealing between the mechanism chamber body and the mechanism chamber panel; the operation of the mechanism chamber panel 31 and the panel, the indication hole sealing member 33 and the sealing ring between them are matched to realize the sealing of the mechanism chamber panel unit 3.
The sealing design of the mechanical interlocking part of the cable chamber door is complex, the mechanical interlocking exists in order to realize the function of opening the cable chamber door only under certain safety conditions, for example, the cable chamber door can be opened only under the condition that a main switch is opened and a grounding switch is closed, and some switches are also added with manual locking and also under the condition that the operation is completed, the locking functions are realized by extending one or more parts out of the operating mechanism part to limit the opening of the cable chamber door, as shown in figure 4, the cable chamber door can be opened only after the interlocking parts 44 and 45 are extracted from the interlocking part 47, the interlocking parts 44, 45, 46 and 47 need to be completely sealed, the sealing of the interlocking device in the prior art mostly adopts a flange-to-seal ring scheme or the sealing similar to a corrugated pipe principle, but when the moving part which needs to extend out of the interlocking device of the cable chamber door can be a combination of a plurality of shafts and sheet metal parts, the situations of more links needing sealing, complex structure and unreliable sealing can occur.
The technical key point of the invention is that the mechanism chamber 1 of the high-voltage switch cabinet is designed to be sealed, and a special sealing box body is not specially made to only seal the operating mechanisms 21 and 22; the plurality of interlocking pieces 44, 45, 46 and 47 of the interlocking device which need to be sealed are not sealed one by one, but the sealing conversion device 41 covers the interlocking pieces 44, 45, 46 and 47 to concentrate the sealing, and the sealing surface is also transferred from a narrow space to a space which is easy for sealing operation. The invention seals the key component mechanism chamber in the ring main unit, the protection grade of the mechanism chamber can reach IP65, the ring main unit can adapt to various environments, and the full working condition operation is really realized.
It should be noted that the above embodiments can be freely combined as necessary. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
