sleeved with a tension spring 6033, two ends of the tension spring 6033 are respectively and fixedly connected to the mounting plate 6034 and the mounting ring 603, the mounting plate 6035 is fixedly connected with a bent rod 6035, the bent 6036 is fixedly connected to the bent rod 6035, and the pressing plate 6036 abuts against the copper nail 1022.
When the mounting block 201 swings, the mounting rod 205 fixedly connected to the mounting block 201 swings synchronously, the mounting rod 205 moves in an arc shape to drive the sliding sheet 301 to slide, when the sliding sheet 301 slides, the pulling rope 3021 pulls the rectangular plate 303, so that when the rectangular plate 303 approaches inwards, the space in the seal box 3 is reduced, and sulfur hexafluoride moves upwards, when two groups of rectangular plates 303 approach each other, the gas in the seal box 3 is extruded into the first piston cylinder 402, at the same time, the fluorinated liquid in the first piston cylinder 402 flows into the resistor 401 in the cooling pipe 4011 through the first pipeline 4022 to be cooled, when the fluorinated liquid passes through the cooling pipe 4011 and then enters the second piston cylinder 5 through the second pipeline 4023, the rack 501 slides upwards to drive the gear 601 to rotate, when the gear 601 rotates, the shift lever 6011 on the gear 601 contacts the sliding rod 6031, and when the cylindrical block 6032 slides to the other side of the rectangular rod 602 beyond the edge angle of the rectangular rod 602, at this time, the pressing plate 6036 on the sliding bar 6031 slaps the brass nails 1022.
The working principle is as follows: when the internal electronic element arrangement structure of the gas insulated switchgear is used, an external wire is connected through the first connecting sheet 3041 and the second connecting sheet 1021, the connecting rod 204 is pulled through the rotation of the pushing control block 2, the connecting rod 204 drives the mounting block 201 to swing around the rotating rod 2011, and accordingly the contact between the first metal sheet 2052 and the second metal sheet 3042 is controlled, so that the connection and the disconnection of a circuit are controlled, when the short circuit condition occurs in the circuit, the resistor 401 connected in parallel on the copper wire 2051 is heated due to the increase of current, at the moment, the resistor 401 transfers the heat to the bimetal elastic sheet 4012, so that the bimetal elastic sheet 4012 bends, the bent bimetal elastic sheet 2 touches the locking block 202, at the moment, the locking block 202 rotates, so that the locking rod 2013 is separated from the locking block 202, the mounting block 201 rotates under the action of the torsion spring 2012, at the moment, the first metal sheet 2052 does not touch the second metal sheet 3042 any more, the circuit is disconnected, when the mounting block 201 swings downwards, the first metal sheet 2052 moves towards the direction far away from the second metal sheet 3042, the circuit is disconnected, when the mounting block 201 swings, the mounting rod 205 fixedly connected to the mounting block 201 swings synchronously, the mounting rod 205 moves in an arc shape, so that when the mounting rod 205 swings, the mounting rod 205 can slide on the mounting ball 3011 and simultaneously drive the sliding piece 301 to slide, when the sliding piece 301 slides, the pulling rope 3021 can pull the rectangular plate 303, because the pulling rope 3021 is inserted and connected in the guide ring 302, the sliding stroke of the rectangular plate 303 is increased, the density of sulfur hexafluoride is greater than that of air, when the rectangular plate 303 moves inwards, the space in the sealing box 3 is reduced, and the sulfur hexafluoride moves upwards to be in contact with the first metal sheet 2052 and the second metal sheet 3042, so that an electric arc is prevented from occurring between the first metal sheet 2052 and the second metal sheet;
when the two groups of rectangular plates 303 approach each other, the gas in the seal box 3 is squeezed into the first piston cylinder 402, so that the first piston plate 4021 in the first piston cylinder 402 is squeezed to slide towards the inside of the first piston cylinder 402, at this time, the fluorinated liquid in the first piston cylinder 402 flows into the cooling pipe 4011 through the first pipeline 4022, the cooling pipe 4011 is wound and connected on the resistor 401, so that the flowing fluorinated liquid cools the resistor 401 to prevent the resistor 401 from being burned out, and meanwhile, the cooling of the resistor 401 enables the bimetal 4012 to restore to the original state, so that the bimetal 4012 no longer blocks the locking block 202;
when the fluorinated liquid enters the second piston cylinder 5 through the second pipeline 4023 after passing through the cooling pipe 4011, the fluorinated liquid absorbs heat generated by the resistor 401 to gasify the fluorinated liquid, so that the upward sliding stroke of the second piston plate 5011 is increased, the rack 501 fixedly connected to the second piston plate 5011 slides upward synchronously when the second piston plate 5011 slides upward, the gear 601 rotates due to the engagement of the rack 501 and the gear 601, the shift lever 6011 on the gear 601 contacts the slide bar 6031 when the gear 601 rotates, the slide 6031 slides on the mounting ring 603, so that the mounting ring 603 rotates, the cylindrical block 6032 slides against the rectangular rod 602 when the slide 6031 rotates along with the mounting ring 603, a shock is generated when the cylindrical block 6032 slides to the other side of the rectangular rod 602 beyond the edge angle of the rectangular rod 602 due to the pulling force of the tension spring 6033, and the pressure plate 6036 on the slide 6031 beats the copper nail 1022, so that the connection between the copper wire 2051 and the copper nail 1022 is loosened and reinforced after being pulled by tripping for a long time.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
