[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a ceramic vacuum interrupter self-closing force and reaction force detection device with high efficiency, which has the following beneficial effects:

[0018] (1) The utility model adopts an I-shaped disk. When the self-closing force and reaction force detection device of the ceramic vacuum arc extinguishing chamber is used with high actual efficiency, the control panel is used to make the solenoid valve, belt conveyor, motor, air pump, first electric telescopic rod and two sets of second electric telescopic rods work. The belt conveyor can push the ceramic vacuum arc extinguishing chamber. When one set of ceramic vacuum arc extinguishing chambers is moved between two sets of first arc-shaped clamping plates on the same side, the air pump works and can fill the gas into the gas storage cavity and the interior of the eight sets of gas cavities through the air guide tube. The gas inside the eight sets of gas cavities can push the eight sets of piston plates. The eight sets of piston plates can drive the eight sets of first arc-shaped clamping plates through the eight sets of piston rods. , wherein two groups of first arc-shaped clamping plates can clamp a group of ceramic vacuum interrupter chambers, and at this time the motor works and can drive the I-shaped disk to rotate through the connecting shaft, and when this group of ceramic vacuum interrupter chambers rotates ninety degrees, the first electric telescopic rod is extended, and when the two groups of second arc-shaped clamping plates move to the side of the moving conductive rod of this group of ceramic vacuum interrupter chambers, the two groups of second electric telescopic rods are extended, and when the two groups of second arc-shaped clamping plates clamp the moving conductive rod of this group of ceramic vacuum interrupter chambers, the air pump extracts the gas inside the gas storage cavity and the eight groups of gas cavities through the air guide pipe, and the eight groups of piston plates drive the eight groups of first arc-shaped clamping plates to reset through the eight groups of piston rods, and the belt conveyor Continuing to work, the next set of ceramic vacuum interrupter can be moved between the two sets of first arc-shaped clamping plates on the same side, and then the air is pumped through the air pipe to fill the air into the air storage cavity and the eight sets of air cavities.

At this time, shortening the first electric telescopic rod can drive the installation frame plate to move up. When the lifting plate presses the pressure sensor, the pressure sensor transmits the pressure data to the external computer in real time. When the moving and static contacts of the ceramic vacuum interrupter are just separated and the external circuit loses power, the pressure sensor reading is the self-closing force value of the ceramic vacuum interrupter contact.

The ceramic vacuum arc chambers separated from the first arc-shaped clamping plates will fall on the upper part of the uppermost group of rubber plates due to gravity, and then fall on the conveying surface of the belt conveyor along the two lower groups of rubber plates. At this time, the three groups of inclined rubber plates can buffer the force of the ceramic vacuum arc chambers falling. When it is necessary to adjust the inclination angle of the three groups of rubber plates, three groups of mounting screws and six groups of mounting nuts are used. The six groups of mounting nuts are rotated clockwise and counterclockwise by hand. When the six groups of mounting nuts are separated from the mounting plate, the three groups of rubber plates can be rotated. When the three groups of rubber plates are rotated to a suitable angle, the six groups of mounting nuts can be rotated in the opposite direction. When the six groups of mounting nuts are in close contact with the mounting plate, the use angle of the three groups of rubber plates is fixed. Through the provided mounting plate, the ceramic vacuum arc chamber can be quickly removed, and at the same time, the ceramic vacuum arc chamber can be prevented from falling and being damaged, thereby improving the practicality of the efficient ceramic vacuum arc chamber self-closing force and reaction force detection device.

[0036] In one embodiment, a support frame 5 is installed at the lower part of the belt conveyor 1 , and the support frame 5 serves to support and fix the belt conveyor 1 .

[0037] Working principle:

[0038] When the self-closing force and reaction force detection device of the ceramic vacuum interrupter with high actual use efficiency is used, the control panel is used to make the solenoid valve, the belt conveyor 1, the motor 13, the air pump 19, the first electric telescopic rod 23 and the two groups of second electric telescopic rods 29 work. The belt conveyor 1 can push the ceramic vacuum interrupter. When a group of ceramic vacuum interrupters moves to between the two groups of first arc-shaped clamping plates 12 on the same side, the air pump 19 works to fill the gas into the gas storage chamber 6 and the eight groups of gas chambers 7 through the air guide tube 18. The gas inside the eight groups of gas chambers 7 can push the eight groups of piston plates 9. The eight groups of piston plates 9 can drive the eight groups of first arc-shaped clamping plates 12 through the eight groups of piston rods 10, wherein the two groups of first arc-shaped clamping plates 12 can clamp a group of ceramic vacuum interrupters. At this time, the motor 13 works and can be connected The shaft 14 drives the I-shaped disk 3 to rotate. When this group of ceramic vacuum interrupter rotates ninety degrees, the first electric telescopic rod 23 is extended. When the two groups of second arc-shaped clamping plates 30 are moved to the side of the moving conductive rod of this group of ceramic vacuum interrupter, the two groups of second electric telescopic rods 29 are extended. When the two groups of second arc-shaped clamping plates 30 clamp the moving conductive rod of this group of ceramic vacuum interrupter, the air pump 19 extracts the gas inside the gas storage chamber 6 and the eight groups of gas chambers 7 through the air guide pipe 18. The eight groups of piston plates 9 drive the eight groups of first arc-shaped clamping plates 12 to reset through the eight groups of piston rods 10. The belt conveyor 1 continues to work, and the next group of ceramic vacuum interrupter can be moved between the two groups of first arc-shaped clamping plates 12 on the same side. Then, the air pump 19 is used to fill the air into the gas storage chamber 6 and the eight groups of gas chambers 7 through the air guide pipe 18. , at this time, the four groups of first arc-shaped clamping plates 12 can clamp two groups of ceramic vacuum interrupters. At this time, the first electric telescopic rod 23 is shortened to drive the installation frame plate to move up. When the lifting plate 31 presses the pressure sensor 25, the pressure sensor 25 transmits the pressure data to the external computer in real time. When the moving and static contacts of the ceramic vacuum interrupter are just separated and the external circuit loses power, the reading of the pressure sensor 25 is the value of the self-closing force of the ceramic vacuum interrupter contact. The first electric telescopic rod 23 is quantitatively shortened to separate the contacts to the rated opening distance. At this time, the reading of the pressure sensor 25 is the value of the reaction force of the ceramic vacuum interrupter contact. The motor 13 continues to work, which can drive the I-shaped disk 3 to continue to rotate ninety degrees. The next group of ceramic vacuum interrupters can perform self-closing force and reaction force Detection, repeating the above operation can continuously perform clamping and self-closing force and reaction force detection on multiple groups of ceramic vacuum arc chambers. When clamping and detecting the ceramic vacuum arc chambers through the provided I-shaped disk 3, there is no need to frequently and repeatedly rotate 90 degrees to reset the clamping structure, thereby improving the working efficiency of the efficient ceramic vacuum arc chamber self-closing force and reaction force detection device. At the same time, according to the above operation, it can be known that during the rotation of the I-shaped disk 3, the eight groups of first arc-shaped clamping plates 12 will clamp four groups of ceramic vacuum arc chambers. The ceramic vacuum arc chambers separated from the first arc-shaped clamping plates 12 will fall on the upper part of the topmost group of rubber plates 21 due to the action of gravity, and then fall on the conveying surface of the belt conveyor 1 along the lower two groups of rubber plates 21. At this time, the three groups of inclined rubber plates 21 can buffer the falling force of the ceramic vacuum arc chambers.When the tilt angle of the three rubber plates 21 needs to be adjusted, the three mounting screws 20 and the six mounting nuts 22 are used to rotate the six mounting nuts 22 clockwise and counterclockwise by hand. When the six mounting nuts 22 are separated from the mounting plate 4, the three rubber plates 21 can be rotated. When the three rubber plates 21 are rotated to a suitable angle, the six mounting nuts 22 can be rotated in the opposite direction. When the six mounting nuts 22 are in close contact with the mounting plate 4, the use angle of the three rubber plates 21 is fixed. The ceramic vacuum interrupter can be quickly removed by setting the mounting plate 4, and the ceramic vacuum interrupter can be prevented from falling and being damaged, thereby improving the practicality of the efficient ceramic vacuum interrupter self-closing force and reaction force detection device.
