[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1-Figure 8 The present invention provides two technical solutions: a continuous distribution cabinet electric variable measuring device, specifically including the following embodiments:

[0029] Embodiment 1: A continuous type power distribution cabinet electric variable measuring device, comprising a protective box 2 and an electric variable measuring device body 1 installed inside the protective box 2, a radiator assembly 3 for accelerating the heat dissipation of the electric variable measuring device body 1 is fixedly arranged on both sides of the inner wall of the protective box 2, a plurality of air inlets are evenly arranged on the outer wall of the protective box 2 and at a position opposite to the radiator assembly 3, a dustproof assembly 4 for filtering dust in the air is arranged inside the air inlet, a track groove 5 is arranged on both sides of the outer wall of the protective box 2 and below the dustproof assembly 4, and a useful sliding arrangement is arranged inside the track groove 5 The driving assembly 6 for driving the dustproof assembly 4 and the radiator assembly 3 to work, the arc-shaped cover plate 7 is fixedly arranged on the opposite side walls of the two driving assemblies 6 and located above the electric variable measuring device body 1. The arc-shaped cover plate 7 is made of stainless steel, has high strength, and can play a good protective effect. The first strong magnet 8 is fixedly arranged on the outer wall of the protection box 2, and the second strong magnet 9 corresponding to the position of the first strong magnet 8 is fixedly arranged on the side wall of the driving assembly 6. The first strong magnet 8 and the second strong magnet 9 cooperate with each other to jointly complete the limitation of the position of the driving assembly 6. The radiator assembly 3 includes a radiator body 31 fixedly arranged on the inner wall of the protection box 2 and a trigger switch 32 fixedly arranged on the outer wall of the radiator body 31 for controlling its opening or closing. The trigger switch 32 and the radiator body 31 are electrically connected through a wire. After the trigger switch 32 is pushed by an external force, the circuit where the radiator body 31 is located is turned on, and the external air can be sucked into the protection box 2 and blown toward the electric variable measuring device body 1, so as to achieve the effect of accelerating the air circulation around the electric variable measuring device body 1. The air inlet is connected to the interior of the radiator body 31 to ensure that air can enter normally. The radiator body 31 is a known technology, and its internal structure and working principle are not described here. The dustproof component 4 includes a filter plate 41 fixedly arranged inside the air inlet and a transmission shaft rotatably arranged inside the filter plate 41. A gear 42 is fixedly arranged at one end of the transmission shaft, and a brush 43 for cleaning dust on the surface of the filter plate 41 is fixedly arranged on the side of the outer wall of the transmission shaft away from the gear 42. A lifting handle for convenient handholding is fixedly arranged on the outer wall of the protective box 2, and a rubber protective cover is fixedly arranged on the outer wall of the lifting handle. The outer wall of the protective box 2 is coated with insulating paint, and the insulating paint is applied in three layers. Before each layer is applied, it is determined that the previous layer of insulating paint is in a dry state.

[0030] Embodiment 2: The main difference between this embodiment and the first technical solution is: a continuous type distribution cabinet electric variable measuring device, the driving assembly 6 includes a side plate 61 fixedly set on the side wall of the arc-shaped cover plate 7 by bolts and an arc-shaped rack 62 detachably fixedly set on the side wall of the side plate 61 and meshingly connected with the gear 42, a plurality of guide wheels 63 are fixedly set on the side wall of the side plate 61 close to the protective box 2, and the guide wheels 63 are slidably set inside the track groove 5, and an arc-shaped guide groove 64 is opened on the side wall of the side plate 61, and a spherical bump 65 that matches the position of the spherical bump 65 is fixedly set inside the arc-shaped guide groove 64. The trigger switch 32 is slidably set inside the arc-shaped guide groove 64, and meets the spherical bump 65 during the sliding process, and the trigger switch 32 is triggered to complete the action of opening or closing the radiator assembly 3.

[0031] When in use, the electric variable measuring device of the continuous distribution cabinet is carried to the detection position, and the arc cover 7 is manually pushed to slide along the track groove 5 until the first strong magnet 8 and the second strong magnet 9 meet, and the two strong magnets attract each other through magnetic force, and the position of the arc cover 7 is restricted. At this time, the body 1 of the electric variable measuring device is exposed outside the protective box 2. While the arc cover 7 slides along the track groove 5, the arc rack 62 drives the gear 42 to mesh and connect, and the arc rack 62 drives the gear 42 to rotate. Since the gear 42 and the brush 43 are fixedly arranged on the same transmission shaft, the gear 42 rotates and drives the brush to clean the surface of the filter plate 41 until the arc rack 62 and the gear 42 are separated, and the brush 43 loses power and ends the cleaning action. At the same time, when the arc cover 7 slides along the track groove 5, the spherical protrusion 65 and the trigger switch 32 meet, and the trigger switch 32 is pushed by the spherical protrusion 65, the circuit where the radiator body 31 is located is turned on, and the radiator body 31 sucks external air to blow in the direction of the electric variable measuring device body 1, and the heat generated by the electric variable measuring device body 1 when working is quickly discharged with the flowing air. Then, the staff uses the electric variable measuring device body 1 to measure the electric variable of the equipment to be detected. The electric variable measurement process is an existing technology and has been widely used in actual production. Therefore, the specific operation process of the electric variable measuring device body 1 is not repeated here. After the electric variable measurement is completed, the arc cover 7 is manually pushed in the opposite direction again. After the thrust is greater than the magnetic force between the first strong magnet 8 and the second strong magnet 9, the two separate, and the spherical protrusion 65 and the trigger switch 32 meet again. The trigger switch 32 is pushed by the spherical protrusion 65, and the circuit where the radiator body 31 is located is disconnected and stops working. At the same time, the arc-shaped rack 62 is restored from the separated state to the meshing state with the gear 42 again. After the gear 42 rotates, it synchronously drives the brush 43 to rotate, and the dust on the outer wall of the filter plate 41 is cleaned again.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
