Description

Technical Field

[0001] The present invention relates to the technical field of circuit breakers, and in particular to an outdoor high-voltage vacuum circuit breaker. Background Art

[0002] The vacuum circuit breaker gets its name because both the arc extinguishing medium and the insulating medium in the contact gap after arc extinguishing are high vacuum. It has the advantages of small volume, light weight, being suitable for frequent operation, and no need for maintenance of arc extinguishing, and is widely used in the distribution network.

[0003] There are certain deficiencies in the existing outdoor high-voltage vacuum circuit breakers during daily use: 1. The existing outdoor high-voltage vacuum circuit breakers do not have the feature of sun protection. When the outdoor high-voltage vacuum circuit breaker is exposed to sunlight for a long time, it is easy to cause component aging, and at the same time, it cannot prevent wild animals that are good at climbing poles (such as squirrels) from damaging the insulation protection layer, which easily leads to the problem of short service life of the outdoor high-voltage vacuum circuit breaker; 2. During the installation process of the outdoor high-voltage vacuum circuit breaker, it is necessary to lift the high-voltage vacuum circuit breaker to the pole for installation by cooperating with the hanging ears and the hoisting rope. However, the traditional hanging ears are all exposed outside the bottom shell and are easily corroded by the external environment and rust, resulting in brittle fission of the hanging ears, which in turn affects the bearing capacity of the ear seat. It is easy to cause the vacuum circuit breaker to fall from the air due to insufficient bearing capacity of the hanging ears, posing a threat to the personal safety of the staff.

[0004] Therefore, it is particularly important to design an outdoor high-voltage vacuum circuit breaker to change the above technical defects and improve the overall practicability. Summary of the Invention

[0038] In this embodiment, please refer to Figure 4 , the lug ejecting mechanism 6 includes a fixing plate 601 arranged inside the groove 201. Internal threaded holes 602 are opened at both the front and rear ends inside the bottom shell 2 and at the bottom of the groove 201. An extrusion bolt 603 is threadedly connected inside the internal threaded hole 602. The top of the extrusion bolt 603 abuts against an ejecting rod 604. A return spring 605 is sleeved outside the ejecting rod 604 at the bottom of the fixing plate 601. The top end of the ejecting rod 604 penetrates through the fixing plate 601 and is connected to a flipping concave plate 607 through a rotating shaft 606. An installation lug 608 is arranged at one end of the flipping concave plate 607. By screwing the extrusion bolt 603 inward with a screwdriver, the extrusion bolt 603 pushes the ejecting rod 604 vertically inside the internal threaded hole 602. With the cooperation of the rotating shaft 606, the ejecting rod 604 lifts the flipping concave plate 607 upward, making the installation lug 608 at the top of the flipping concave plate 607 face vertically upward for hanging the lifting rope hook. After the high-altitude transportation is completed, remove the hook and operate in the reverse direction to hide the installation lug 608 inside the groove 201, thereby reducing contact with the external environment and extending the service life of the installation lug;

[0039] A through hole for the movable connection with the ejecting rod 604 is opened inside the fixing plate 601 at a position corresponding to the ejecting rod 604.

[0040] Workflow of the present invention: During the installation of the high-voltage vacuum circuit breaker, first, the bottom housing 2 is fixedly installed at the top of the driving base 1 through bolts. Then, the high-voltage vacuum circuit breaker is lifted to the pole for installation by means of a lifting rope. Before hoisting, the construction worker screws the extrusion bolt 603 inward with a screwdriver, so that the extrusion bolt 603 pushes the ejector rod 604 vertically inside the internal thread hole 602. With the cooperation of the rotating shaft 606, the ejector rod 604 lifts the flipping concave plate 607 upward, making the mounting hanging ear 608 at the top of the flipping concave plate 607 face vertically upward for hanging the hoisting rope hook. After the high-altitude transportation is completed, the hook is removed and the reverse operation is performed, so that the mounting hanging ear 608 is hidden inside the groove 201, thereby reducing contact with the external environment and prolonging the service life of the mounting hanging ear; During the daily use of the circuit breaker terminal 3, the temperature sensor 511 will detect the outdoor temperature in real time. When the detected outdoor temperature is too high, it will send a signal to the processor 512 and process it into a command to send to the controller 513. At this time, the controller 513 will send the command to the forward and reverse motor 404. When the forward and reverse motor 404 receives the signal, it will drive the gear 405 to rotate, so that the racks 406 on both sides will move horizontally accordingly, and with the assistance of the slide rails 402 and the sliders 403, it will drive the left protective cover 501 and the right protective cover 502 to move, thereby driving the two groups of protective covers to move in the same direction to close, avoiding damage to the circuit breaker caused by long-term exposure to sunlight and strong winds, and without manual operation, it is more intelligent and the operation is more convenient. At the same time, heat dissipation slots 503 and heat dissipation fans 505 are provided to dissipate heat from the circuit breaker terminal; At the same time, a monitoring head 509 is provided to monitor the surrounding environment of the circuit breaker driven by the rotating motor 508. When the monitoring head 509 captures the approach of wild animals during daily monitoring, it will send a signal to the processor 512, and the controller 513 will drive the sound and light alarm 510 to make a sound to disperse the wild animals, improving the safety of the circuit breaker use environment and avoiding the circuit breaker terminal from being attacked. In addition, the solar cell 504 provided on the top of the cover can convert sunlight into electrical energy and store it in the storage battery 506, making reasonable use of energy and being more environmentally friendly. Therefore, the overall protective cover structure composed of the left protective cover 501 and the right protective cover 502 can protect the circuit breaker terminal 3 and the bottom housing 2, avoiding damage caused by sun exposure and animal gnawing.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
