Description

Technical Field

[0001] The utility model relates to the field of electrical technology, in particular to a photovoltaic compensation controller. Background Art

[0002] As a part of the current new energy industry, the photovoltaic industry can convert light energy into electrical energy. The use of electrical energy requires the cooperation of the power grid. Therefore, a large number of equipment such as electric control cabinets are needed to build the power grid.

[0003] Existing photovoltaic compensation controllers, such as the reactive compensation controller disclosed in patent CN204967280U, have a central controller, a voltage acquisition circuit, a current acquisition circuit, and a switching switch. After the voltage acquisition circuit and the current acquisition circuit acquire the power conditions of the three-phase power grid, they are transmitted to the central controller. When the central controller receives data information of voltage and current zero crossing, the central controller outputs a switching signal to the switching switch, the switching switch is closed, and the power capacitor is put into reactive compensation to meet the compensation demand. In addition, the existing photovoltaic compensation controller is usually installed in a way of being embedded in the cabinet, that is, the photovoltaic compensation controller itself is a whole. When installed, the cabinet is provided with an opening slot, and the photovoltaic compensation controller is inserted into the opening slot and clamped to achieve stable installation of photovoltaic compensation on the cabinet.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the following embodiments are combined with the attached Figure 1 To Attachment Figure 3 The technical solution provided by the utility model is described in detail, but the following content is not intended to limit the utility model.

[0021] Figure 1 This is a structural diagram of an embodiment of a photovoltaic compensation controller of the utility model; Figure 2 This is a schematic diagram of the installation of the slideway, the covering slide plate and the limiting structure of a preferred embodiment of the utility model. Figure 1 and Figure 2As shown, the photovoltaic compensation controller provided in this embodiment includes: a shell 1, a display panel 2 and a covering slide 3. At this time, the shell 1 includes an inner cavity, and an opening connected to the inner cavity is opened on the front side of the shell 1, and the central controller of the photovoltaic compensation controller is arranged in the inner cavity, and the display panel 2 is arranged at the opening, and a display 21 and a plurality of control buttons 22 are arranged on the display panel 2, and the display 21 and the control buttons 22 are electrically connected to the central controller to facilitate data display and control adjustment.

[0022] Specifically, the outer edge of the display panel 2 protrudes from the outer wall of the housing 1, so that the display panel 2 can form a limit on the outer side of the housing 1, so that when it is subsequently embedded in the opening groove on the cabinet, the limit formed by the outer edge of the display panel 2 can be pressed against the notch of the opening groove, and mutually supported to achieve stable installation on the cabinet. In addition, a slide 23 arranged in the vertical direction is provided on both side walls of the display panel 2, and at the same time, a cover slide 3 is provided on the front side of the display panel 2, and support arms 31 extending toward the slide 23 are provided on both sides of the cover slide 3. The side structure of the cover slide 3 is expanded by the support arm 31, which provides conditions for the subsequent use with the slide 23. In addition, a slider 32 is provided on each support arm 31 to slide into the corresponding slide 23, which can not only ensure that the slider 32 can slide in the corresponding slide 23, but also enable the cover slide 3 to be located at the front side of the display panel 2, meeting the opening and covering requirements of the display 21 and the control button 22 on the display panel 2. In addition, a limiting structure 4 is provided on the display panel 2 and in each slide groove 23. When the cover slide 3 is moved into position, the limiting structure 4 can support the slider 32 and limit the movement of the slider 32, thereby preventing the cover slide 3 from accidentally moving down under the action of gravity and causing the failure problem to occur, and maintaining the stability and reliability during covering. At this time, when the cover slide 3 is moved into position, the cover slide 3 covers the display 21 and a number of control buttons 22. The cover slide 3 covers the display 21 and the control buttons 22 on the display panel 2, realizing external protection, preventing the entry of foreign dust and other impurities that affect the operation and service life of electronic components, and also preventing the occurrence of accidental collision damage or mis-touch, with higher safety assurance.

[0023] More specifically, the bottom end of the slide groove 23 is a sealed groove, that is, the bottom of the slide groove 23 is sealed to achieve truncation of the bottom of the slide groove 23, and when the covering slide plate 3 moves down to its position, the bottom of the slider 32 abuts against the groove wall at the bottom end of the slide groove 23, thereby preventing the slider 32 from continuing to move downward, thereby avoiding the problem of the slider 32 escaping from the slide groove 23 when moving downward, and also improving the structural reliability and higher safety assurance.

[0024] More specifically, the slide grooves 23 on the display panel 2 are all strip-shaped rectangular grooves. At this time, the two side walls of each slide groove 23 are both planar structures. At the same time, the slider 32 is set to a rectangular block, so that the two side walls of the slider 32 are also planar structures. Therefore, when the slider 32 is installed in the slide groove 23, the two side walls of the slider 32 can be fitted with the two side walls of the slide groove 23 to achieve limiting, preventing the slider 32 from rotating in the slide groove 23 and causing the cover slide plate 3 to deflect relative to the display panel 2, thereby improving the directional stability of the cover slide plate 3 when sliding, and the structural design is more reasonable.

[0025] Figure 3 for Figure 1 The enlarged view of part A in the figure. Figure 1 , Figure 2 as well as Figure 3 As shown, the limiting structure 4 disposed in the slide groove 23 and limiting the upwardly moving slider 32 further comprises a sleeve 41, a limiting ball 42 and a spring. During installation, an embedding groove 24 is provided on both side walls of the display panel 2. At this time, one end of each embedding groove 24 is connected to the slide groove 23 on the corresponding side, so that the limiting structure 4 installed in the embedding groove 24 can act on the slider 32 in the slide groove 23. In addition, a sleeve 41 is embedded in the embedding groove 24, and the embedding groove 24 provides an installation space for the sleeve 41. At the same time, the end of the sleeve 41 close to the slide groove 23 is arranged in a constricted manner, so that the end of the inner hollow of the sleeve 41 can form a constricted mouth. At this time, the limiting ball 42 and the spring are both arranged in the sleeve 41, and the limiting ball 42 is arranged in the end of the sleeve 41 close to the slide groove 23, that is, the limiting ball 42 is located in the inner hollow of the sleeve 41 and in the end arranged in a constricted mouth, and one side of the limiting ball 42 extends out from the constricted mouth. At the same time, one end of the spring is pressed against the limiting ball 42, and the other end of the spring is pressed against the embedding groove 24. On the side wall of one end away from the slide groove 23, that is, when the sleeve 41 is installed in the embedded groove 24 and the limiting ball 42 and the spring are installed in the inner space of the sleeve 41, one side of the limiting ball 42 extends from the end of the sleeve 41 with a constricted opening to the slide groove 23 under the action of the spring, and when it moves into place on the slider 32, the slider 32 moves to the limiting ball 42 and squeezes the limiting ball 42, so that the limiting ball 42 compresses the spring, so that the limiting block can press the slider 32 to prevent the slider 32 from continuing to move, thereby preventing the covering slider 3 from accidentally moving downward under the action of gravity, thereby improving the stability and reliability of the covering slider 3 when covering. Preferably, a recessed limiting groove is provided on one side surface of the slider 32 close to the limiting ball 42. When the slider 32 moves to the limiting ball 42, the limiting ball 42 can be inserted into the limiting groove, which can not only emit a prompt sound as a reminder that the slider 32 has moved up to the right position, but also improve the reliability of the limiting ball 42 in limiting the slider 32.

[0026] More specifically, a protrusion 25 protruding toward the groove is also provided on the side wall of the embedding groove 24. At this time, a groove 411 corresponding to the protrusion 25 is also provided on the outer wall of the sleeve 41, so that when the sleeve 41 is subsequently installed in the embedding groove 24, the protrusion 25 can be embedded in the groove 411, that is, the sleeve 41 is limited in the axial direction in the embedding groove 24 by the protrusion 25 and the groove 411, thereby maintaining the stability of the sleeve 41 when installed in the embedding groove 24, preventing the spring from pushing the sleeve 41 as a whole into the slide groove 23 and blocking the slider 32 from moving in the slide groove 23, and the structural design is more reasonable.

[0027] More specifically, a sticky hair 5 is provided on the side of the covering slide 3 close to the display panel 2, and a soft contact structure is formed by the sticky hair 5 on the side of the covering slide 3 close to the display panel 2. At this time, the sticky hair 5 is adhered to the edges around the covering slide 3, that is, the gap between the covering slide 3 and the display panel 2 is covered by the sticky hair 5 to ensure the protective effect. At the same time, when the covering slide 3 is subsequently moved relative to the display panel 2, the dust and other impurities attached to the display panel 2 can be cleaned away by the sticky hair 5 to achieve cleaning.

[0028] More specifically, an observation window 33 is also provided on the cover slide 3. At this time, when the cover slide 3 is moved up to the right position, the observation window 33 and the display 21 can be arranged directly opposite each other, so that the operator can obtain the display information of the display 21 through the observation window 33 without moving the cover slide 3 down, which is more convenient to use and avoids the problem of frequently moving up and down the cover slide 3. In addition, a transparent plate 34 is provided in the observation window 33, which can meet the covering requirements and facilitate the observation of the operator, and the structural design is more reasonable.

[0029] More specifically, the housing 1, the display panel 2, and the cover plate are all made of plastic materials, which can not only meet the insulation requirements, but also facilitate injection molding and manufacturing. In addition, the transparent plate 34 is set to be an acrylic plate, which reduces the weight of the transparent plate 34 while meeting the transparency requirement, thereby achieving a lightweight structure.

[0030] The photovoltaic compensation controller provided in this embodiment includes a shell 1, a display panel 2 and a covering slide 3; the display panel 2 with a display 21 and a plurality of control buttons 22 is installed at the opening of the shell 1, and slide grooves 23 arranged in the vertical direction are provided on both sides of the display panel 2. At the same time, a covering slide 3 is provided on one side of the display panel 2 where the display 21 and the control buttons 22 are provided, and sliders 32 are installed on both sides of the covering slide 3 through support arms 31 and slide into the corresponding slide grooves 23, and a limiting structure 4 is provided in the slide groove 23, so that when the slider 32 moves up to a position, the limiting structure 4 can be used to limit the covering slide 3 to cover the display 21 and the control buttons 22, and when the slider 32 moves down to a position, the display 21 and the control buttons 22 can be exposed, which is convenient for observation and control and adjustment. It can not only prevent external dust from entering the shell 1 and affecting the movement and service life of electronic components, but also prevent collision damage and accidental touching of control buttons, thereby improving safety.
