[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.
[0025] Please refer to Figures 1-3 , a lightning arrester monitoring device, including a monitoring box 1, a ventilation duct 2 is rotatably connected to the monitoring box 1, a wind guide plate 21 is fixedly arranged on the ventilation duct 2, the wind guide plate 21 and the ventilation duct 2 are in the same plane, the ventilation duct 2 is communicated with the inside of the monitoring box 1, an air outlet is provided on the monitoring box 1, and a wind guide device 3 is slidably connected in the ventilation duct 2.
[0026] Through the arranged ventilation duct 2, under the action of external wind force, the wind guide plate 21 is in the same direction as the wind movement direction, so that the wind enters the detection box through the ventilation duct 2 and takes away the heat generated by the internal device and discharges it from the air outlet. Through the arranged wind guide device 3, when the ventilation duct 2 faces the wind direction directly in the front or side, the wind can enter the ventilation duct 2.
[0027] Further, the ventilation duct 2 is arranged at the bottom of the detection box, and the air outlet is arranged at the upper part of the side wall of the monitoring box 1. When air is heated, its volume will expand, and the air density is small and the weight is light, that is, the hot air inside the monitoring box 1 is concentrated in the upper part. Through this setting, the effect of heat dissipation and temperature reduction is improved.
[0028] Further, the ventilation duct 2 includes a horizontal pipe 22 and a vertical pipe 23 that are communicated with each other, the vertical pipe 23 is rotatably connected to the bottom of the monitoring box 1, the horizontal pipe 22 is fixedly arranged at the end of the vertical pipe 23, and the wind guide device 3 is slidably connected in the horizontal pipe 22. The middle of the horizontal pipe 22 is connected to the vertical pipe 23, and both ends can intake air.
[0029] Further, the wind guide device 3 includes a left sliding cover 31 and a right sliding cover 32, the left sliding cover 31 and the right sliding cover 32 are slidably connected in a chute 33 inside the horizontal pipe 22, a left sliding rod 34 is fixedly connected to the left sliding cover 31, a right sliding rod 35 is fixedly connected to the right sliding cover 32, and the right sliding rod 35 is slidably connected inside the left sliding rod 34.
[0030] When the wind enters the horizontal pipe 22 from one side of the horizontal pipe 22, the wind blows the corresponding sliding cover, causing it to slide towards the other sliding cover and exposing the vertical pipe 23, thereby guiding the wind to enter the monitoring box 1 along the horizontal pipe 22 and the vertical pipe 23, rather than directly discharging from the other end of the horizontal pipe 22. Through the wind guide device 3, both ends of the horizontal pipe 22 can intake air, improving the heat dissipation and temperature reduction effect.
[0031] Furthermore, a rain shield 4 is fixedly arranged at the air outlet to prevent rainwater or debris in the wind from directly entering the monitoring box 1 through the air outlet.
[0032] Furthermore, desiccants are arranged both inside the vertical pipe 23 and at the air outlet to prevent internal dampness from affecting the service life of each device. Filters can also be arranged at the air outlet and inside the vertical pipe 23 to reduce the dust entering the monitoring box 1.
[0033] The present utility model also provides a capacitive device for a power system, which includes any one of the above lightning arrester monitoring devices. Therefore, this capacitive device for a power system should also have the effects of the above lightning arrester monitoring device, and will not be elaborated here.
[0034] Working principle: Under the action of external wind force, the wind guide plate 21 is in the same direction as the wind movement direction. When the wind enters the horizontal pipe 22 from one side of the horizontal pipe 22, the wind blows the corresponding sliding cover, causing it to slide towards the other sliding cover, and exposing the vertical pipe 23. Thereby, the wind is guided to enter the monitoring box 1 along the horizontal pipe 22 and the vertical pipe 23, taking away the heat generated by the internal device and discharging it from the air outlet.
[0035] Only some exemplary embodiments of the present utility model are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
