Description

Technical Field

[0001] The present invention relates to the field of switch devices, and more particularly, to a switch device and a control method. Background Art

[0002] Low-voltage draw-out switchgear is widely used in power plants, substations, industrial and mining enterprises, and the power distribution cabinets of high-rise buildings, namely the main power center PC and the motor control center MCC. It is used as a low-voltage complete set of distribution equipment for power distribution, centralized motor control, and reactive power compensation in power generation and power supply systems with an alternating current of 50 - 60 Hz, a rated working voltage of 660 V and below, and a rated current of 4000 A and below.

[0003] Traditional switch cabinet doors with glass windows generally include a switch door panel and a glass plate. An observation window is provided on the switch door panel. The glass plate is larger than the observation opening and is adhered to the switch door panel with strong glue. However, since this glass plate is fixed to the switch door panel with strong glue, during the handling or transportation of the switch cabinet, violent vibration may cause the glass plate to fall off. Moreover, the glass plate on the switch cabinet has the disadvantages of being inconvenient to replace, clean, and maintain.

[0004] In the prior art, Chinese Invention Patent No. CN202121643739.6 discloses an observation glass protection device for a switch cabinet, including a mounting shell fixedly installed on the switch cabinet door. A protection component is fixedly connected inside the mounting shell. A fixing component for restricting the position of the protection component is arranged inside the mounting shell. An auxiliary mechanism is fixedly connected to both the inside and the back of the mounting shell. A glass plate located behind the protection component is fixedly connected to the back of the mounting shell. Although this patent has a certain degree of protection, the observation glass protection device needs to be manually controlled, resulting in poor flexibility of the observation glass protection device. Once the situation of forgetting to cover the glass plate after use occurs, if the switch cabinet tilts and falls to the ground at this time, the observation glass will still be broken and damaged, thus failing to achieve a good protection effect.

[0005] In view of this, the present invention is specifically proposed. Summary of the Invention

[0043] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. In the embodiments of the present invention, the descriptions such as "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement them. When the combination of the technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0044] The present invention will be described in detail below with reference to the drawings and in combination with embodiments.

[0045] In the prior art, Chinese Patent Application No. CN202121643739.6 discloses an observation glass protection device for a switch cabinet, including an installation shell fixedly installed on the cabinet door of the switch cabinet. A protection component is fixedly connected inside the installation shell, a fixing component for restricting the position of the protection component is arranged inside the installation shell, the inside and the back of the installation shell are fixedly connected with an auxiliary mechanism, and a glass plate located on the back of the protection component is fixedly connected to the back of the installation shell. Although this patent has a certain degree of protection, the observation glass protection device needs to be manually controlled, resulting in poor flexibility of the observation glass protection device. Once the situation of forgetting to cover the glass plate after use occurs, if the switch cabinet tilts and falls to the ground at this time, the observation glass will still be broken, thus failing to achieve a better protection effect.

The glass window 2 and the protection device 3 are provided on the front panel 11 and / or the rear panel and / or the upper panel and / or the lower panel 12 and / or the left panel and / or the right panel of the cabinet body 1.

[0053] Preferably, in this embodiment, specifically, as Figure 1 shown, the glass window 2 and the protection device 3 are provided on the front panel 11 of the cabinet body 1.

[0054] This setting facilitates the staff to directly observe the situation of the switching device inside the cabinet body 1 through the glass window 2 on the front panel 11.

[0055] Specifically, the installation position of the protection device 3 on the front panel 11 is not limited. The protection device 3 is installed on the upper side and / or the lower side and / or the left side and / or the right side of the glass window 2 on the front panel 11.

[0056] Preferably, in this embodiment, as Figure 1 shown, the protection device 3 is installed on the upper side of the glass window 2 on the front panel 11.

[0057] This setting can improve the protection and safety of the protection device 3 and prevent rainwater from entering the inside of the protection device 3.

[0058] Specifically, as Figure 2As shown, the protection device 3 includes a protection driving device 303, a transmission device 304, and a protection plate 307. The protection driving device 303 is connected to the transmission device 304, and the transmission device 304 is connected to the protection plate 307.

[0059] This setting facilitates the protection device 3 to drive the protection plate 307, thereby facilitating the protection of the glass window 2.

[0060] Specifically, as Figure 2 shown, the protection device 3 is installed on the cabinet 1 through an installation housing 301. An installation frame 302 is arranged inside the installation housing 301. The installation frame 302 includes a first installation plate 3021 and a second installation plate 3022, and the first installation plate 3021 and the second installation plate 3022 are vertically connected.

[0061] This setting improves the installation stability of the protection device 3.

[0062] More specifically, as Figure 2 shown, the first installation plate 3021 and the second installation plate 3022 are connected in a T shape. This setting further improves the installation stability of the protection device 3.

[0063] More specifically, an opening is arranged at the bottom of the installation housing 301, and the opening is matched with the protection plate 307.

[0064] Specifically, the protection driving device 303 is installed on the first installation plate 3021. The second installation plate 3022 is vertically connected to the middle position below the first installation plate 3021. A sliding cavity 309 with both ends closed is arranged on the second installation plate 3022. A sliding device 306 is arranged inside the sliding cavity 309, and the sliding device 306 is connected to the protection plate 307. A transmission device 304 is also installed on the second installation plate 3022. One end of the transmission device 304 is connected to the protection driving device 303, and the other end of the transmission device 304 is connected to the sliding device 306.

[0065] The protection driving device 303 is not specifically limited. In this embodiment, the protection driving device 303 is set as a stepping motor. Through the high-precision rotation of the stepping motor, the control of the protection device 3 by the motor is more accurate.

[0066] The transmission device 304 is not specifically limited. The transmission device 304 can be set as an eccentric wheel, and the transmission device 304 can also be set as a lead screw.

[0067] Preferably, as Figure 2As shown, in this embodiment, the transmission device 304 is set as a lead screw, and the sliding device 306 is directly connected to the lower end of the sleeve 305 of the lead screw. The forward and reverse rotations of the protection driving device 303 drive the sliding device 306 to reciprocate, thereby driving the protection plate 307 to move up and down.

[0068] There is no specific limitation on the sliding device 306. Preferably, the sliding device 306 is set as a slider.

[0069] Specifically, the protection device 3 at least includes a first protection structure 31 and a second protection structure 32, and the first protection structure 31 and the second protection structure 32 are on the front and back sides of the front panel 11.

[0070] This setting further improves the protection performance of the protection device 3. It can not only protect the glass window 2 from the front side of the glass window 2 to prevent the switch cabinet from tilting and hitting an external object to damage the glass window 2; but also protect the glass window 2 from the back side of the glass window 2. On the one hand, it can prevent the debris caused by the switch cabinet tilting and hitting an external object to damage the glass window 2 from entering the interior of the switch cabinet, avoiding damage to the internal components of the switch cabinet; on the other hand, it can prevent the internal components of the switch cabinet from loosening and sliding to damage the glass window 2.

[0071] Preferably, in this embodiment, as Figure 3 shown, the first protection structure 31 and the second protection structure 32 are symmetrically arranged on the front and back sides of the front panel 11 of the cabinet body 1.

[0072] This setting further improves the protection performance of the protection device 3. It can not only protect the glass window 2 from the front side of the glass window 2 to prevent the switch cabinet from tilting and hitting an external object to damage the glass window 2; but also protect the glass window 2 from the back side of the glass window 2. On the one hand, it can prevent the debris caused by the switch cabinet tilting and hitting an external object to damage the glass window 2 from entering the interior of the switch cabinet, avoiding damage to the internal components of the switch cabinet; on the other hand, it can prevent the internal components of the switch cabinet from loosening and sliding to damage the glass window 2.

[0073] Specifically, the control device can simultaneously control whether the first protection structure 31 and / or the second protection structure 32 are enabled or disabled.

[0074] This setting further improves the flexibility of the protection device 3 on the switch cabinet.

[0075] Specifically, as Figure 2 shown, a shock-absorbing and sound-absorbing body 308 is provided on the protection device 3.

[0076] This setting can, on the one hand, reduce the impact of the vibration of the cabinet body 1 on the glass window 2 and improve the protection performance of the protection device 3. On the other hand, it can also reduce the noise transmitted through the gap of the glass window 2 of the switch cabinet, thus avoiding interference with the staff around the switch cabinet.

[0077] Specifically, as Figure 2 shown, a shock-absorbing and noise-reducing body 308 is provided on the protection plate 307.

[0078] This setting facilitates the up and down movement of the shock-absorbing and noise-reducing body 308 following the protection plate 307.

[0079] Specifically, the setting form of the shock-absorbing and noise-reducing body 308 on the protection plate 307 is not limited. The shock-absorbing and noise-reducing body 308 can be set in a straight line on the protection plate 307; the shock-absorbing and noise-reducing body 308 can also be set in a square shape on the protection plate 307.

[0080] Preferably, in this embodiment, as Figure 5 shown, the shock-absorbing and noise-reducing body 308 is set in a square shape on the protection plate 307, and the shock-absorbing and noise-reducing body 308 is arranged in a square shape along the four sides of the protection plate 307.

[0081] This setting enables the shock-absorbing and noise-reducing body 308 to cooperate with the gap of the glass window 2. On the one hand, it can reduce the impact of more vibrations of the cabinet body 1 on the glass window 2 and improve the protection performance of the protection device 3. On the other hand, it can also reduce more noise transmitted through the gap of the glass window 2 of the switch cabinet, thus avoiding interference with the staff around the switch cabinet.

[0082] Specifically, as Figure 4 shown, a first sound-absorbing hole 3081 and a second sound-absorbing hole 3082 are provided on the shock-absorbing and noise-reducing body 308, and the first sound-absorbing hole 3081 and the second sound-absorbing hole 3082 are cross-arranged inside the shock-absorbing and noise-reducing body 308.

[0083] This setting can, on the one hand, improve the sound-absorbing effect of the shock-absorbing and noise-reducing body 308; on the other hand, it reduces the thickness of the shock-absorbing and noise-reducing body 308, facilitating the shock-absorbing and noise-reducing body 308 to be squeezed into the inside of the sliding cavity 309 following the protection plate 307.

[0084] Specifically, as Figure 4 shown, the diameter of the first sound-absorbing hole 3081 is set larger than the diameter of the second sound-absorbing hole 3082.

[0085] This setting can, on the one hand, further improve the sound-absorbing effect of the shock-absorbing and noise-reducing body 308; on the other hand, it further reduces the thickness of the shock-absorbing and noise-reducing body 308, facilitating the shock-absorbing and noise-reducing body 308 to be squeezed into the inside of the sliding cavity 309 following the protection plate 307.

[0086] Specifically, the specific material of the shock-absorbing and sound-insulating body 308 is not limited. Preferably, in this embodiment, the material of the shock-absorbing and sound-insulating body 308 is polyurethane soft foam. This setting further improves the shock-absorbing effect and sound-insulating effect of the shock-absorbing and sound-insulating body 308 in the first aspect. In the second aspect, setting the shock-absorbing and sound-insulating body 308 as polyurethane soft foam facilitates the shock-absorbing and sound-insulating body 308 to be squeezed into the interior of the sliding cavity 309 following the protection plate 307. In the third aspect, setting the shock-absorbing and sound-insulating body 308 as polyurethane soft foam facilitates the simultaneous removal of water vapor and dust on the glass window 2, improving the observation effect.

[0087] Specifically, as Figure 6 shown, a vibration judgment device 4 is provided on the cabinet body 1. The vibration judgment device 4 is electrically connected to the control device.

[0088] This setting associates the vibration judgment device 4, the control device, and the protection device 3. The setting of the vibration judgment device 4 can quickly and accurately judge whether the switch cabinet is in a stationary state, so that the control device can quickly and accurately enable or disable the protection device 3, thereby greatly improving the flexibility and protection performance of the protection device 3.

[0089] More specifically, as Figure 6 shown, the vibration judgment device 4 is provided at the center of the lower panel 12.

[0090] More specifically, as Figure 6 and Figure 7 shown, the vibration judgment device 4 includes a center ball 41 located at the center position of the lower panel 12, a plane 42 supporting the center ball 41, and a sliding resistor 43 arranged along the connection line in the corresponding direction between the center ball 41 and the column 121.

[0091] More specifically, as Figure 8 shown, the sliding resistor 43 includes a sliding part 431 and a stationary part 432. The sliding part 431 is sleeved outside the stationary part 432, and the outer end of the sliding part 431 is connected to the center ball 41.

[0092] In Figure 5 it, the number of the sliding resistors 43 is five.

[0093] More specifically, in this embodiment, the number of the sliding resistors 43 is the same as the number of the columns 121. In this embodiment, the number of the sliding resistors 43 is set to four (not shown in the figure).

[0094] When the switch cabinet is impacted and vibrates and tilts, the center ball 41 of the vibration judgment device 4 tilts and slides to one side, pushing the sliding part 431 of the sliding resistor 43 on the tilted side to slide towards the stationary part 432, reducing the resistance; the sliding part 431 of the sliding resistor 43 on the other side slides towards the outside of the stationary part 432, increasing the resistance; when the control device detects a change in the resistance of any one of the sliding resistors 43 of the vibration judgment device 4, it indicates that the switch cabinet is in a non-stationary state, and the control device controls the protection device 3 to be enabled. When the control device detects that the resistance of any one of the sliding resistors 43 of the vibration judgment device 4 does not change within the time period T1, it indicates that the switch cabinet is in a stationary state, and the control device controls the protection device 3 to be closed.

[0095] A sound sensor (not shown in the figure) is provided inside the switch cabinet.

[0096] For the switch device, in addition to including the switch cabinet, it also includes other related components such as a busbar chamber and a cable chamber. Since the specific structures and specific assembly relationships of its related components are all prior arts, they will not be elaborated here.

[0097] The switch device described in this embodiment associates the protection device 3, the control device, the shock-absorbing and sound-absorbing body 308, and the vibration judgment device 4, with novel concept and ingenious design, achieving multiple effects. First, it greatly improves the flexibility and protection performance of the protection device 3 on the switch cabinet; second, it greatly reduces the noise transmitted from the gap of the glass window 2 of the switch cabinet, avoiding interference to the staff around the switch cabinet; third, it can remove water vapor and dust on the glass window 2 at the same time, improving the observation effect.

[0098] Embodiment 2

[0099] In this embodiment, a control method for a switch device is proposed. The control method of the switch device uses a switch device as described in any one of the above, and the control method of the switch device specifically includes the following steps:

[0100] S1. Power on;

[0101] S2. Detect the state of the switch cabinet;

[0102] Specifically, the state of the switch cabinet is judged by the vibration judgment device 4.

[0103] S3. Judge whether the state of the switch cabinet is in a vibrating state. If not, execute S4; if so, execute S6;

[0104] S4. Detect the volume inside the switch cabinet;

[0105] Specifically, the volume inside the switch cabinet is detected by a sound sensor.

[0106] S5. Determine whether the volume inside the switch cabinet is greater than the volume threshold. If so, execute S6; if not, execute S7;

[0107] Among them, the volume threshold is a system - preset data, and the specific value of the volume threshold is not limited.

[0108] S6. The control device controls the protection device 3 to be enabled;

[0109] S7. The control device controls the protection device 3 to be closed.

[0110] For the control method of a switch device described in this embodiment, steps S1 - S7 are interrelated and inseparable. The state of the switch cabinet in step S2 is used as the primary judgment condition. Steps S2 and S3 detect and analyze whether there is a risk of damage to the glass window 2 of the switch cabinet by detecting whether the switch cabinet is in a vibrating state, which facilitates the control device to accurately control whether the protection device 3 is enabled or closed, improving the flexibility and protection performance of the protection device 3. When the switch cabinet is in a vibrating state, it indicates that there is a risk of damage to the glass window 2 of the switch cabinet, and step S6 is entered, where the control device controls the protection device 3 to be enabled; when the switch cabinet is in a non - vibrating state, it indicates that there is no risk of damage to the glass window 2 of the switch cabinet, and step S4 is entered. The volume inside the switch cabinet in step S4 is used as the secondary judgment condition. Steps S4 and S5 detect and analyze whether it is necessary to enable the protection device 3 to eliminate noise by detecting whether the volume inside the switch cabinet is greater than the volume threshold, which facilitates the control device to accurately control whether the protection device 3 is enabled or closed, greatly reducing the noise transmitted from the gap of the glass window 2 of the switch cabinet and avoiding interference to the staff around the switch cabinet. When the volume inside the switch cabinet is greater than the volume threshold, it is necessary to enable the protection device 3 to eliminate noise, and step S6 is entered, where the control device controls the protection device 3 to be enabled; when the volume inside the switch cabinet is less than or equal to the volume threshold, it is not necessary to enable the protection device 3 to eliminate noise, and step S7 is entered, where the control device controls the protection device 3 to be closed.

[0111] In summary, steps S1 - S7 are interrelated and inseparable. First, it greatly improves the flexibility and protection performance of the protection device 3 on the switch cabinet; second, it greatly reduces the noise transmitted from the gap of the glass window 2 of the switch cabinet and avoids interference to the staff around the switch cabinet; third, it can remove water vapor and dust on the glass window 2 at the same time, improving the observation effect.

[0112] The control method of the switch device described in this embodiment is interrelated with the switch device described in Embodiment 1, and steps S1 to S7 are interrelated and inseparable, so that the protection device 3, the control device, the shock-absorbing and sound-absorbing body 308, and the vibration judgment device 4 are associated with each other. It has a novel concept and ingenious design, and has multiple effects.
