[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model embodiment discloses an AGC / AVC control device for a new energy plant.

[0029] Example 1

[0030] The utility model provides Figure 1-4 The new energy plant AGC / AVC control device shown includes a control host 1 and a control display 2. An AGC / AVC control module 3 is embedded in the control host 1. Cable connectors 4 are fixedly provided on the sides of the control host 1 and the control display 2. A control cable 5 is connected between the two cable connectors 4. A protective tube 6 is sleeved on the outer side of the control cable 5. Both ends of the protective tube 6 are fixedly sleeved with rings 7, which are sleeved on the cable connectors 4.

[0031] Before controlling the power, the control host 1 and the control display 2 are connected through the cooperation of the control cable 5 and the cable connector 4. At this time, the power-related information signals can be transmitted through the AGC / AVC control module 3, and the power allocation is completed. After the control cable 5 is set, the protective tube 6 can be put on the outside of the control cable 5, and the ring 7 can be put on the outside of the cable connector 4, and the position of the protective tube 6 is determined. Since the length of the protective tube 6 is fixed, the protective tube 6 can protect the control cable 5 when it is accidentally pulled, and the control cable 5 cannot be loosened from the cable connector 4, so that the control information can be stably transmitted, ensuring the stability of power operation.

[0032] Example 2

[0033] Embodiment 2 is based on Embodiment 1 in order to fix the position of the protection tube 6. Figure 2 and Figure 4 As shown, the side walls of the control host 1 and the control display 2 are fixed with two symmetrically arranged connecting plates 8, the two connecting plates 8 are located on both sides of the cable connector 4, and a positioning connection mechanism is provided between the protective tube 6, the positioning connection mechanism includes a fixing rod 9, the fixing rod 9 is fixedly arranged inside the connecting plate 8, the rod wall of the fixing rod 9 is slidably sleeved with a card plate 10, both sides of the ring 7 are fixedly provided with a vertical plate 11, the top of the vertical plate 11 is provided with a card slot for matching the card plate 10, the upper end of the vertical plate 11 on the side close to the fixing rod 9 is inclined, and contacts and cooperates with the upper end of the card plate 10, the lower end of the card plate 10 is provided with a sliding hole for matching the fixing rod 9, the lower end of the fixing rod 9 is sleeved with a spring 12, the two ends of the spring 12 are fixedly connected to the card plate 10 and the fixing rod 9 respectively, the two adjacent connecting plates 8 are provided with a groove on the side away from each other, the spring 12 is arranged in the groove, the interior of the vertical plate 11 is provided with a guide hole, and the connecting plate 8 is slidably arranged in the guide hole.

[0034] After the cable connector 4 is connected to the control cable 5, the ring 7 can be brought close to the cable connector 4. With the cooperation of the inclined surface of the side wall of the vertical plate 11, the ring 7 can make the vertical plate 11 push the card plate 10 when it moves horizontally, so that the card plate 10 slides along the fixed rod 9 and stretches the spring 12. When the top of the vertical plate 11 moves to the bottom of the card plate 10, the elastic force of the spring 12 can restore the card plate 10 to quickly rebound and insert it into the card slot. After the position of the card plate 10 is determined, the two ends of the protective tube 6 can be connected to the control display 2 and the control host 1, so as to effectively protect the internal control cable 5. At the same time, the setting of the guide hole and the connecting plate 8 can make the card plate 10 stably connected to the vertical plate 11, thereby improving the connection stability.

[0035] Example 3

[0036] Embodiment 3 is based on Embodiment 1 in order to further protect the control cable 5 and ensure the stability of AGC / AVC control. Figure 1 and Figure 3 As shown, the protection tube 6 can be a stainless steel cable protection tube, and a plurality of air holes 13 arranged at intervals are opened on the tube wall of the protection tube 6, and dust-proof filters 14 are fixedly embedded in the plurality of air holes 13.

[0037] By setting the protective tube 6, the control cable 5 can be effectively wrapped and protected, while reducing the transmission of internal information of the control cable 5 by the external magnetic field, ensuring stable control transmission, and at the same time, the setting of the air vents 13 and the dust filter 14 can transfer the heat generated during the use of the control cable 5 to the outside. At the same time, when air flow exchange is performed, dust in the external air is prevented from entering the protective tube 6 to affect the connection stability of the cable connector 4 and the control cable 5.

[0038] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
