Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", "vertical", "horizontal", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element to be referred must have a specific orientation, be constructed and operated in a specific orientation, and thus are not to be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

As shown in fig. 1-3, it is a structure diagram of a vacuum load switch according to a preferred embodiment of the present invention, in this embodiment, the heat dissipation device 3 is respectively fixed to the middle of the front and the back of the housing 2, in order to quickly dissipate heat, therefore, the inside of the heat dissipation device 3 is fixedly installed with the fan 34, generally speaking, the vacuum load switch is generally hung on the electric wire column, the long-time use is realized, the detachable heat dissipation device box 32 installed on the heat dissipation device 3 is convenient for maintenance workers to replace, the fan 34 is controlled by the display screen 4 through the connecting wire, the fan 34 is installed outside the heat dissipation plate 31, the blades of the heat dissipation plate 31 are distributed at equal intervals, and because of being in the outdoor environment, the rain-proof baffle 33 is installed outside the fan 34 without blowing rain.

In this embodiment, the sensor 22 of temperature is arranged at the upper end of the inside of the housing 2, the detection device of the sensor 22 feeds information back to the display screen 4 through a connecting wire, the display screen 4 performs judgment processing, and when the internal temperature is too high, the fan 34 in the heat dissipation device 3 is started.

In this embodiment, an insulating base 29 is arranged below the sensor 22, the first fuse 25 is installed on the upper right side of the insulating base 29, the second fuse 28 is installed on the upper left side of the insulating base 29, and a knife switch 26 is connected between the first fuse 25 and the second fuse 28. Knife switch 26 adopts split type structure, can separate first fuse 25 and second fuse 28 through the knife switch and cut off the power supply, the knife switch is the riveting structure simultaneously, area of contact is bigger when connecting, make it more steady when carrying out power transmission, simultaneously under the effect of double-fuse through first fuse 25 and second fuse 28, can carry out the power transmission of large capacity, of course the security also can be higher, knife switch 26's both ends below all is provided with spring assembly 27, spring assembly 27 installs in insulating base 29 upper end, through spring assembly 27, separate knife switch 26, through squeezing spring assembly 27, the spring has elasticity, make knife switch 26 connect once more, when having avoided needing to connect, can not connect in time, lead to power failure, knife switch 26's top is provided with micro-motion motor 23, micro-motion motor 23's output is connected with the promotion head 24 that has insulating device, when needing to break knife switch 26, button control micro-motion motor 23 through display screen 4, make the drive of motor 23 promote head 24 and carry out the downward work, make the knife switch separate, cut off the power supply.

The working principle is as follows:

because this vacuum load switch is used for transmitting large capacity power transmission, can produce the heat when using, through first fuse 25 and second fuse 26, can carry out power transmission, because long-time transmission, can produce the heat, sensor 22 real-time detection, will detect data and transmit display screen 4 through the connecting wire, display screen 4 carries out control calculation, when the temperature exceedes the scope, display screen 4 automatic start heat abstractor 3's fan 34 dispels the heat, when the temperature reaches the standard, display screen 4 control heat abstractor 3 stops working. When internal power-off is needed, a control button on the display screen 4 is pressed to control the micro-motor 23, the driving pushing head 23 works downwards to disconnect the switch 26, when power-on is needed, the micro-motor 23 drives the pushing head 23 to work upwards, and power-on is quickly recovered by the elasticity of the spring device 27 below the switch 26. Because the vacuum load switch is arranged at a high place, the radiating fins are inconvenient to replace, and therefore, the drawing type more convenient replacement is designed.

The above-mentioned details of the present invention are further described in detail with reference to the specific embodiments, and it is not assumed that the embodiments of the present invention are limited to these descriptions, and it will be apparent to those skilled in the art that the present invention can be implemented by a plurality of simple deductions or replacements without departing from the spirit of the present invention, which should be considered as belonging to the protection scope defined by the claims submitted by the present invention.
