In order to reduce the size of the cabinet body 1 to the maximum extent, the opening and closing operation of the isolating switch 17 is more convenient and labor-saving, and the opening and closing of the isolating switch 17 adopts a mode of combined movement of a horizontal rotating shaft and the vertical pull rod 13. Specifically, as follows, the cabinet body 1 is provided with a horizontal rotating shaft 26, the front end of the horizontal rotating shaft 26 extends to the front part of the cabinet body 1, the rear end of the horizontal rotating shaft 26 extends to the rear part of the cabinet body 1, the horizontal rotating shaft 26 is provided with a crank arm 12, the crank arm 12 is connected with one end of a vertical pull rod 13, the other end of the vertical pull rod 13 is connected with a disconnecting switch 17, the front door 2 of the cabinet body 1 is provided with a disconnecting switch operation hole 6 for rotating the horizontal rotating shaft 26, and the disconnecting switch operation hole 6 is opposite to one end of the horizontal rotating shaft 26. When the isolating switch is used, an operator operates on the front side of the cabinet body 1, the horizontal rotating shaft 26 is rotated through the isolating switch operating hole 6, the horizontal rotating shaft 26 drives the crank arm 12 to rotate, and then the crank arm 12 pulls the vertical pull rod 13 to move up and down, so that the isolating switch 17 meshes are separated and combined.

When the vacuum circuit breaker 25 is closed, the breaker opening and closing rod 5 in the vacuum circuit breaker 25 moves downwards, and the pull rod 29 is driven to move downwards. The pull rod 29 is connected with the breaker end crank arm 30, so that the breaker end crank arm 30 is driven to rotate clockwise by taking the rotating shaft 32 as a center; when the breaker end lever 30 rotates clockwise, the rotating shaft 32 is driven to rotate clockwise, and the lock end lever 31 is driven to rotate clockwise. Because the lock rod 28 and the lock rod end crank arm 31 are in hinged connection, the lock rod end crank arm 31 drives the lock rod 28 to extend rightwards, and the baffle 27 of the operation hole is prevented from moving downwards. At this time, the operation hole shutter 27 shields the disconnecting switch operation hole 6, and the operator cannot operate the horizontal rotation shaft 26, thereby achieving the purpose of restricting the disconnection and connection of the disconnecting switch 17. And vice versa.
As shown in fig. 5, 6 and 7, the rear end of the horizontal rotating shaft 26 is provided with a horizontal rotating shaft rear hook plate 11, the horizontal rotating shaft rear hook plate 11 is in a bar shape, a rear door strip hole 35 through which the horizontal rotating shaft rear hook plate 11 can pass is vertically formed in the rear door 8 of the cabinet body 1, the length of the horizontal rotating shaft rear hook plate 11 is larger than the width of the rear door strip hole 35, and when the isolating switch 17 is closed, the horizontal rotating shaft rear hook plate 11 is in a horizontal position; when the disconnecting switch 17 is disconnected, the hook plate 11 is positioned at the vertical position behind the horizontal rotating shaft.
As shown in fig. 7, when the horizontal rotating shaft 26 is at the closing angle of the isolating switch 17, the hook plate 11 behind the horizontal rotating shaft is at the horizontal position, and at this time, the hook plate 11 behind the horizontal rotating shaft hooks the rear door 8 through the rear door strip hole 35, so that the rear door 8 is in a locked state, and an operator cannot open the rear door 8, thereby avoiding the error entering the electrified interval. As shown in fig. 6, when the horizontal rotating shaft 26 is at the opening angle of the isolating switch 17, the hook plate 11 behind the horizontal rotating shaft rotates 90 ° to be at the vertical position, the hook plate 11 behind the horizontal rotating shaft coincides with the axis of the back door strip hole, the external dimension of the hook plate 11 behind the horizontal rotating shaft is smaller than the external dimension of the back door strip hole 35, and the locking of the back door 8 is released.
In order to reduce the temperature rise generated when the switch equipment passes through the heavy current, as shown in fig. 1, the top of the cabinet body 1 is provided with a cross flow fan 20 for radiating the switch equipment so as to ensure that the temperature rise of the switch equipment meets the standard requirement.
