Detailed Description
The present invention will be described in further detail with reference to the drawings and the detailed description below, in order to make the above objects, features and advantages of the present invention more comprehensible.
As shown in fig. 1 to 5, the small-sized high-voltage cabinet valve mechanism provided by the invention comprises a fixed supporting plate 101, a linkage crank arm 102, a guide supporting plate 103, a first connecting rod 104, a second connecting rod 105, an upper valve 106 and a lower valve 107.
The upper shutter 106 and the lower shutter 107 are both provided on a contact box mounting bracket 201, and an upper contact box 202 and a lower contact box 203 are mounted on the contact box mounting bracket 201. The upper shutter 106 is used to open and close the upper contact box 202, and the lower shutter 107 is used to open and close the lower contact box 203.
The fixed support plate 101 and the guide support plate 103 are both disposed at one side of the contact box mounting bracket 201.
The center of the interlocking crank arm 102 is connected to the fixed support plate 101 through a rotating shaft, and the interlocking crank arm 102 can rotate up and down around the fixed support plate 101 through the rotating shaft.
As shown in fig. 3, a first hinge hole 1021 is formed at the top end of the interlocking crank arm 102, a first hinge shaft 1041 is disposed at one end of the first link 104, and the one end of the first link 104 is hinged to the interlocking crank arm 102 through the first hinge shaft 1041 and the first hinge hole 1021. The other end of the first link 104 is hinged to the upper shutter 106.
When the interlocking crank arm 102 rotates upward around the fixed support plate 101, the first link 104 drives the upper shutter 106 to move upward along the contact box mounting bracket 201, at this time, the upper shutter 106 is opened, and the upper contact box 202 is in an open state.
When the interlocking crank arm 102 rotates downward around the fixed support plate 101, the first link 104 drives the upper shutter 106 to move downward along the contact box mounting bracket 201, at this time, the upper shutter 106 is closed, and the upper contact box 202 is in a closed state.
The guide support plate 103 is disposed outside the fixed support plate 101 and near the fixed support plate 101, and the guide support plate 103 plate can move up and down in the vertical direction. One end of the second connecting rod 105 is movably connected to the guide supporting plate 103, and the other end of the second connecting rod 105 is hinged to the lower valve 108. Specifically, as shown in fig. 5, an arc-shaped first guide groove 1032 is formed on the guide support plate 103, and a first guide shaft 1031 is provided on the right side of the first guide groove 1032.
The second link 105 includes a front link portion 1051 and a rear link portion 1052 that are hinged end to end, a second hinge shaft 1053 is disposed at the front end of the front link 1051, and a second elongated guide slot 1054 is formed in the middle of the front link 1051. The second hinge shaft 1053 is penetratingly coupled in the first guide groove 1032 and is slidable along the first guide groove 1032, and the first guide shaft 1031 is penetratingly coupled in the second guide groove 1054 and is slidable along the second guide groove 1054.
When the guide support plate 103 moves upward, the first guide shaft 1031 and the second hinge shaft 1053 slide along the second guide groove 1054 and the first guide groove 1032, respectively, and finally the second link 105 is bent downward, so as to drive the lower shutter 107 to move downward, at this time, the lower shutter 107 is opened, and the lower contact box 203 is in an open state.
When the guide support plate 103 moves downward, the first guide shaft 1031 and the second hinge shaft 1053 slide along the second guide groove 1054 and the first guide groove 1032, respectively, so that the second link 105 is finally opened upward, thereby driving the lower shutter 108 to move upward, and at this time, the lower shutter 107 is closed, and the lower contact box 203 is in a closed state.
As shown in fig. 1, when the vacuum circuit breaker trolley 300 is in the separated position (non-operating state), the upper shutter 106 and the lower shutter 107 cover the left end openings of the upper contact box 202 and the lower contact box 203, respectively, so that the upper contact box 202 and the lower contact box 203 remain in a closed state.
As shown in fig. 2, when the vacuum interrupter trolley 300 is directed toward the contact box mounting bracket 201 until reaching the operating position, the interlocking crank arm 102 and the guide support plate 103 synchronously operate to open the upper and lower shutters 106 and 107. Thus, the upper moving contact 301 and the lower moving contact 302 on the vacuum circuit breaker trolley 300 can respectively enter the upper contact box 202 and the lower contact box 203 and respectively plug into the fixed contacts (not shown) in the upper contact box 202 and the lower contact box 203.
Compared with a small-sized high-voltage cabinet valve mechanism in the prior art, the valve mechanism can realize automatic opening and closing of the valve, thereby preventing misoperation of an maintainer and preventing electric shock accidents caused by opening the valve under the condition that the high-voltage cabinet is electrified.
The invention has been described above in sufficient detail with a certain degree of particularity. It will be appreciated by those of ordinary skill in the art that the descriptions of the embodiments are merely exemplary and that all changes that come within the true spirit and scope of the invention are desired to be protected. The scope of the invention is indicated by the appended claims rather than by the foregoing description of the embodiments.
