Description

Technical Field

[0001] This utility model relates to the field of circuit breaker component assembly technology, and specifically to an assembly machine for disconnecting switches of a common-enclosure circuit breaker. Background Technology

[0002] A common-enclosure circuit breaker is a high-voltage switchgear that houses three-phase circuit breakers within a single enclosure. It offers advantages such as compact structure, high reliability, and convenient maintenance. Three-phase electricity is a common power supply method in power systems, widely used in industry, commerce, and some large residential areas. Three-phase electricity refers to a power source composed of three alternating current potentials with the same frequency, equal amplitude, and phases differing by 120° sequentially. These three alternating current potentials are typically referred to as phase A, phase B, and phase C. The main function of a disconnecting switch is to provide a clear disconnection point in the circuit, ensuring that the circuit is safely disconnected during equipment maintenance or repair.

[0003] Utility model patent document CN203553718U discloses an outdoor pole-mounted switchgear with a built-in disconnecting switch, including a vacuum interrupter, a disconnecting switch, a circuit breaker operating mechanism, a disconnecting switch operating mechanism, an inflatable sealed housing, incoming line insulating terminals, and outgoing line insulating terminals. The disconnecting switch, vacuum interrupter, and circuit breaker operating mechanism are built into the inflatable sealed housing. The vacuum interrupter is fixedly sealed within the outgoing line insulating terminals, and the moving end of the vacuum interrupter is connected to the disconnecting switch. The disconnecting switch is in contact with or disconnects from the incoming line insulator. The overall structure is a pole-mounted, three-phase common-enclosure structure, using an overhead incoming and outgoing line method. The disconnecting switch is a blade type, including a disconnecting switch contact blade and a disconnecting switch main shaft conductor. The rotation angle of the contact blade can be from 45 degrees to 180 degrees; when the contact blade contacts the stationary contact seat of the incoming line terminal, the main circuit is connected; when it disengages from the stationary contact seat, the main circuit is disconnected. The contact blades are mounted on an insulated spindle, and the three-phase contact blades actuate simultaneously when the insulated spindle rotates. The insulated spindle is connected to the output shaft of the disconnector switch operating mechanism.

[0004] like Figure 1 As shown, in a common-enclosure circuit breaker, the locking holes of three disconnect switches 10 used for three-phase power are passed through an insulated spindle 9; when the insulated spindle 9 rotates, the three disconnect switches 10 move simultaneously. Traditionally, the insulated spindle is manually passed through the locking holes of the disconnect switches, but manual assembly is inefficient.

[0005] Therefore, in order to improve the assembly efficiency of disconnecting switches and insulating spindles, there is an urgent need in this technical field for a disconnecting switch assembly machine for common-enclosure circuit breakers. Utility Model Content

[0036] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0037] Please see Figures 1 to 15 The preferred embodiment of this utility model.

[0038] A disconnector assembly machine for a common-enclosure circuit breaker, comprising:

[0039] Frame 1, telescopic drive device 2, guide rail 3, push seat 4, first guide seat 5, second guide seat 6, support 7;

[0040] The guide rail 3 is fixedly connected to the frame 1. The bottom end of the push seat 4 is slidably connected to the guide rail 3. The telescopic end of the telescopic drive device 2 is fixedly connected to the left end of the push seat 4. The right end of the push seat 4 is provided with a push groove 41, which is used to place the left end of the insulating spindle 9. The telescopic drive device 2 is located to the left of the guide rail 3. The first guide seat 5 is fixedly disposed to the right of the guide rail 3. The first guide seat 5 is provided with a first guide groove 51, which is used to place the right end of the insulating spindle 9. The second guide seat 6 is fixedly disposed to the first guide seat 5. To the right, the second guide seat 6 is provided with a second guide groove 61, which is aligned with the first guide groove 51. A positioning space 8 is formed between the second guide seat 6 and the first guide seat 5. The support 7 is fixedly disposed in front of the positioning space 8. The positioning space 8 and the support 7 cooperate to place the disconnect switch 10. The disconnect switch 10 has a locking hole 101, which is located between the first guide groove 51 and the second guide groove 61. When the push seat 4 pushes the insulating spindle 9 to the right, the right end of the insulating spindle 9 can pass through the locking hole 101.

[0041] The beneficial effects or advantages of this utility model are as follows: the insulating spindle 9 is stably placed in the pushing groove 41 and the first guide groove 51, the disconnect switch 10 is stably placed in the positioning space 8 and the support 7, the telescopic drive device 2 generates force to push the insulating spindle 9 through the locking hole 101 of the disconnect switch 10 with the help of the pushing seat 4, the first guide groove 51 and the second guide groove 61 effectively prevent the position of the insulating spindle 9 from deviating, reduce the intensity of manual labor, and improve the assembly efficiency of the disconnect switch 10 and the insulating spindle 9.

[0042] The first guide groove 51 and the second guide groove 61 have the same shape. The insulated spindle 9 can slide in the first guide groove 51 and the second guide groove 61.

[0043] Furthermore, there are three second guide seats 6, which are arranged at intervals to the right of the first guide seat 5. The second guide seat on the left and the first guide seat form a first phase positioning space, the second guide seat in the middle and the second guide seat on the left form a second phase positioning space, and the second guide seat on the right and the second guide seat in the middle form a third phase positioning space. Three supports are respectively provided in front of the first phase positioning space, the second phase positioning space, and the third phase positioning space. The first phase positioning space, the second phase positioning space, and the third phase positioning space are respectively used to place the three-phase disconnect switch.

[0044] The beneficial effects of this technical solution are: the insulated spindle quickly and sequentially passes through the locking holes of the three-phase disconnect switches. There are three disconnect switches (i.e., disconnect switches 10) in the common-box circuit breaker, which are used to disconnect or close the current loops of the three phases of electricity respectively.

[0045] Furthermore, the support 7 is provided with a positioning groove 71.

[0046] The beneficial effect of this technical solution is that it helps to improve the positioning efficiency of the disconnector switch 10.

[0047] Furthermore, the push seat 4 has a blocking block 42, which is located on the left side of the push groove 41.

[0049] Furthermore, the telescopic drive device 2 is a telescopic cylinder.

[0050] The beneficial effects of this technical solution are: the telescopic cylinder causes the push seat 4 to move back and forth along the guide rail 3. When the push seat 4 moves to the right and passes the insulating spindle 9 through the locking holes 101 of the three disconnect switches 10, the push seat 4 moves to the left. At this time, the left end of the insulating spindle 9 disengages from the push groove 41, and the push seat 4 returns to the initial position.

[0051] Furthermore, the disconnect switch 10 is a knife-type contact.

[0052] There are many different shapes of the disconnect switch 10 in the prior art. In this embodiment, the disconnect switch 10 is a contact knife, with a locking hole 101 at one end of the contact knife and the other end of the contact knife placed in the positioning seat.

[0053] Furthermore, the insulating spindle 9 is in the shape of a regular hexagonal prism, and the clasp 101 is a regular hexagonal hole.

[0054] When the insulating spindle 9 is rotated, the insulating spindle 9 also rotates the isolating switch 10 simultaneously; the insulating spindle 9 is a regular hexagonal prism shape, which is a preferred choice of this utility model.

[0055] The working method of the disconnector assembly machine for the common-enclosure circuit breaker of this utility model:

[0056] The workers first place the insulating spindle 9 on the push seat 4 and the first guide seat 5, with the left end of the insulating spindle 9 placed in the push groove and the right end of the insulating spindle 9 placed in the first guide groove 51; and place the part of the disconnect switch 10 with the locking hole 101 in the positioning space 8, and the part of the disconnect switch 10 away from the locking hole 101 in the support 7. The three-phase disconnect switches are placed in the first phase positioning space, the second phase positioning space, and the third phase positioning space, respectively; then the telescopic drive device 2 is activated, and the push seat 4 moves to the right along the guide rail 3, causing the insulating spindle 9 to move to the right. The insulating spindle 9 passes through the locking holes 101 of the three disconnect switches 10 in sequence. During this process, the insulating spindle 9 passes through the second guide groove 61 in sequence. The telescopic drive device 2 then moves the push seat 4 to the left. At this time, the left end of the insulating spindle 9 disengages from the push groove 41, and the insulating spindle 9 remains in the first guide seat 5 and the second guide seat 6. The push seat 4 returns to its initial position; the workers remove the assembled disconnect switch 10, and then place a new insulating spindle 9 and a new disconnect switch 10 on the present invention to continue the assembly work.

[0057] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
