Description

Technical Field

[0001] This utility model relates to the field of pole-mounted circuit breaker technology, and in particular to a primary and secondary isolation combined pole-mounted circuit breaker. Background Technology

[0002] With the rapid development of my country's economy and the continuous increase in power supply, especially the increasing dependence of various customers on electricity, pole-mounted circuit breakers are often used in the interconnection, sectionalizing, and branch lines of the power grid to improve power supply reliability. However, the management of pole-mounted circuit breakers is a weak link in county-level power supply enterprises. Only by incorporating them into standardized and institutionalized management can they play their due role; otherwise, it will directly affect the enterprise's safety management and power supply reliability. The management of pole-mounted circuit breakers should be controlled from the design stage, with pole-mounted circuit breakers on each line distributed in a tiered manner to avoid cascading tripping caused by faults at the end of the line.

[0003] Utility model patent CN212570831U discloses a pole-mounted circuit breaker, including a base. Both ends of the base are connected to mounting strips, and both ends of the mounting strips are threaded with mounting bolts. Each end of the upper surface of the mounting strips is provided with a protective component to prevent corrosion of the bolt nuts. The protective component includes a protective ring connected to the upper surface of the mounting strip, which surrounds the bolt nuts. The upper end of the protective ring is detachably connected to a sealing plate for closing the upper opening of the protective ring via a limiting member. The mounting bolt is placed inside the protective ring and tightened. The sealing plate is then installed on the protective ring via the limiting member, thereby isolating the bolt nuts from the outside environment, reducing contact with air and moisture, preventing nut corrosion, and avoiding interference with the disassembly of the circuit breaker.

[0004] However, this utility model still has shortcomings. In actual use, the pole-mounted circuit breaker needs to be installed outdoors. At the same time, birds will build nests inside the pole-mounted circuit breaker during the breeding season. Their droppings and liquids will contaminate the insulating bushing of the pole-mounted circuit breaker, reduce the external insulation strength of the porcelain insulator, and also corrode the insulating bushing, thus causing the pre-test data to fail. In addition, bird nests are composed of a large number of flammable debris such as dry grass and dried flowers, and may even contain items such as iron wire. With the rapid increase in temperature and load in summer, the bird nest may spontaneously combust, causing the pole-mounted circuit breaker to catch fire. Utility Model Content

[0005] The main purpose of this utility model is to provide a primary and secondary isolation combined pole-mounted circuit breaker, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A primary and secondary isolation combined pole-mounted circuit breaker includes a support frame, an upper insulator, a middle insulator, and a disconnect switch. A driving mechanism is provided at the lower end of the support frame. The driving mechanism includes a fixed frame fixedly connected to the lower end of the support frame. A mounting plate is fixedly connected to the lower end of the fixed frame. A metal plate is fixedly connected to the front end of the mounting plate. A friction strip is fixedly connected to the inner wall of the metal plate. A stabilizing frame is fixedly connected to the lower end of the mounting plate. A rotating shaft is movably mounted on the inner side of the stabilizing frame. A rotating disk is fixedly connected to the lower end of the rotating shaft. A connecting rope is fixedly connected to the rear end of the rotating disk. A striking ball is fixedly connected to the rear end of the connecting rope. A motor is installed at the upper end of the rotating shaft.

[0008] Preferably, the rear end of the motor is fixedly connected to a mounting base, and there are two sets of mounting brackets.

[0009] Preferably, the metal plate is fitted over the outside of one set of insulators and disconnectors, the metal plate is U-shaped, there are multiple sets of friction strips, and the stabilizer is L-shaped.

[0010] Preferably, the rotating disk is located inside the metal plate, there is a gap between the metal plate and the rotating disk, and the rear end of the fixed base is fixedly connected to the front end of the stabilizer.

[0011] Preferably, the upper insulator is installed at the front end of the support frame, the middle insulator is installed at the lower end of the upper insulator, and the disconnect switch is installed at the lower end of the middle insulator.

[0012] Preferably, a lower insulator is installed at the rear end of the disconnector, and the rear end of the lower insulator is installed at the front end of the mounting plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The rotating disk is driven by a motor, which causes the disk to swing and hit the ball through the connecting rope. Under the action of inertia, the ball is thrown outward of the rotating disk and then comes into contact with the metal plate. This makes it easier for the ball to generate vibration between the friction strip and the metal plate, which in turn makes the metal plate produce a sound and drives away birds, preventing them from nesting on the surface of the upper, middle and lower insulators.

[0015] 2. The metal plate generates vibration sound waves, which in turn shake off the dry grass and other foreign objects accumulated on the surface of the upper, middle and lower insulators. This shaking off of dry grass and other foreign objects can prevent the surface temperature of the upper, middle and lower insulators from becoming too high. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-4 As shown, a primary and secondary isolation combined pole-mounted circuit breaker includes a support frame 1, an upper insulator 2, a middle insulator 3, and a knife switch 4. A driving mechanism 6 is provided at the lower end of the support frame 1. The driving mechanism 6 includes a fixed frame 61 fixedly connected to the lower end of the support frame 1. A mounting plate 62 is fixedly connected to the lower end of the fixed frame 61. A metal plate 63 is fixedly connected to the front end of the mounting plate 62. A friction strip 64 is fixedly connected to the inner wall of the metal plate 63. A stabilizing frame 65 is fixedly connected to the lower end of the mounting plate 62. A rotating shaft 66 is movably installed on the inner side of the stabilizing frame 65. A rotating disk 67 is fixedly connected to the lower end of the rotating shaft 66. A connecting rope 68 is fixedly connected to the rear end of the rotating disk 67. A striking ball 69 is fixedly connected to the rear end of the connecting rope 68. A motor 610 is installed at the upper end of the rotating shaft 66.

[0023] In this embodiment, a fixed base 611 is fixedly connected to the rear end of the motor 610. There are two sets of fixed frames 61. A metal plate 63 is fitted on the outside of the insulator 3 and the knife switch 4 in one set. The metal plate 63 is U-shaped. There are multiple sets of friction strips 64. The stabilizer 65 is L-shaped. The rotating disk 67 is located inside the metal plate 63. There is a gap between the metal plate 63 and the rotating disk 67. The rear end of the fixed base 611 is fixedly connected to the front end of the stabilizer 65.

[0024] Specifically, during the nesting season, motor 610 is first started, causing the rotating shaft 66 to rotate. This, in turn, causes the rotating shaft 66 to rotate the rotating disk 67 inside the metal plate 63. The rotating disk 67, via the connecting rope 68, swings and strikes a ball 69. Due to inertia, the ball 69 is thrown outward from the rotating disk 67, causing it to contact the metal plate 63. The ball 69 vibrates against the metal plate 63 via the friction strip 64, causing the metal plate 63 to emit sound. This sound is perceived by the birds. The birds are driven away by the rotation of the rotating disk 67 driven by the motor 610. The rotating disk 67 is then swung by the connecting rope 68 to hit the ball 69. Under the action of inertia, the ball 69 is swung outward from the rotating disk 67, and then the ball 69 comes into contact with the metal plate 63. This makes it easier for the ball 69 to generate vibration between the friction strip 64 and the metal plate 63, so that the metal plate 63 emits a sound, which drives away the birds and prevents them from nesting on the surface of the upper insulator 2, middle insulator 3 and lower insulator 5.

[0025] In this embodiment, the upper insulator 2 is installed at the front end of the support frame 1, the middle insulator 3 is installed at the lower end of the upper insulator 2, the knife switch 4 is installed at the lower end of the middle insulator 3, and the lower insulator 5 is installed at the rear end of the knife switch 4. The rear end of the lower insulator 5 is installed at the front end of the mounting plate 62.

[0026] Specifically, the metal plate 63 generates vibration sound waves, which in turn shake off the foreign objects such as dry grass accumulated on the surface of the upper insulator 2, middle insulator 3, and lower insulator 5. This removal of the foreign objects can prevent the surface temperature of the upper insulator 2, middle insulator 3, and lower insulator 5 from becoming too high.

[0027] Working principle:

[0028] In use, first install the support frame 1 on the utility pole, and then gradually install the wires on the upper insulator 2, middle insulator 3, and lower insulator 5. During the bird nesting season, first start the motor 610, causing the motor 610 to drive the rotating shaft 66 to rotate. This causes the rotating shaft 66 to drive the rotating disk 67 to rotate inside the metal plate 63. The rotating disk 67, via the connecting rope 68, swings and strikes the ball 69. Due to inertia, the ball 69 swings outward from the rotating disk 67, causing it to contact the metal plate 63. The ball 69 vibrates against the metal plate 63 via the friction strip 64, generating a sound that drives away birds. The vibration waves generated by the metal plate 63 further amplify the sound. The sound waves shake away the accumulated dry grass and other foreign objects on the surfaces of the upper insulator 2, middle insulator 3, and lower insulator 5, thus preventing the surfaces of the upper insulator 2, middle insulator 3, and lower insulator 5 from becoming too hot. The rotating disk 67 is driven by the motor 610 to rotate, which causes the rotating disk 67 to swing and strike the ball 69 through the connecting rope 68. Under the action of inertia, the striking ball 69 is swung outward from the rotating disk 67, thus making the striking ball 69 come into contact with the metal plate 63. This facilitates the generation of vibration between the striking ball 69 and the metal plate 63 through the friction strip 64, thereby causing the metal plate 63 to emit sound, which can drive away birds and prevent them from nesting on the surfaces of the upper insulator 2, middle insulator 3, and lower insulator 5.
