Abstract
Description
Technical Field
[0001] The utility model relates to the field of line loss detection equipment, in particular to a line loss alarm. Background Art
[0002] Line loss is the abbreviation of power loss in the power grid. It refers to the power loss and loss in the transmission, transformation, distribution and marketing of power from power plants to power users. Specifically, it refers to the active, reactive power and voltage loss generated when current flows through various power equipment in the power grid (from the user's billing power meter to all the user's power equipment, excluding the user's billing power meter) within a certain period of time. It is usually referred to as active power loss.
[0003] Most of the existing line loss detection and alarm methods use a method of passing cables through current transformer alarms to implement line loss detection on the lines. In distribution sites, for ease of management, cables and current transformer alarms are mostly installed in the site's chassis. In order to prevent the current transformer alarm from sliding on the line, the current transformer alarm is usually fixed in the chassis. When the wiring in the chassis is more complicated, the position of the current transformer alarm cannot be adjusted, and some cables need to be operated to change the path to adapt to the current transformer alarm. Cables are easily gathered, affecting the orderly arrangement of cables in the chassis, which affects manual wiring operations. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Example: Reference Figure 1-3 A line loss alarm shown in the figure includes a current transformer alarm 1, on which a linkage support 2 is provided, and connecting sleeves 21 are provided at both ends of the linkage support 2. Extension columns 31 are passed through the connecting sleeves 21, and the ends of the extension columns 31 exposed from the connecting sleeves 21 are connected through a mounting seat 3. During the daily use of the line loss alarm, the mounting seat 3 is usually fixedly installed at a fixed position in the chassis. When the linkage support 2 and the connecting sleeve 21 move along the distribution direction of the extension column 31, the distance between the linkage support 2 and the mounting seat 3 can be adjusted to achieve the purpose of adjusting the distance between the current transformer alarm 1 and the mounting seat 3, so that the current transformer alarm 1 can be suitable for lines in different positions and can be suitable for different wiring environments.
[0023] A plurality of inclined limiting grooves 32 are provided on the surface of the extension column 31, and a clamping block 4 is provided on the connecting sleeve 21 located on one side of the current transformer alarm 1. When the distance between the current transformer alarm 1 and the mounting seat 3 is adjusted, the clamping block 4 can be connected with the limiting groove 32 at a suitable position, locking the connecting sleeve 21 and the extension column 31, thereby maintaining the stability of the current transformer alarm 1.
[0024] Since the limiting groove 32 is an inclined structure, the card block 4 is a V-shaped structure and one of the inclined blocks is inserted into the inner side of the limiting groove 32. Therefore, when one of the inclined blocks of the card block 4 is inserted into the inner side of the limiting groove 32, if it is hit by an external force, the moving path of the card block 4 is not easy to coincide with the direction of the external force. Therefore, the external force impact is not easy to affect the card block 4, thereby improving the stability of the current transformer alarm 1 after moving to different positions.
[0025] like Figure 4 , Figure 5 As shown, the linkage support 2 is provided with a channel 22, the limiting groove 32 is exposed at a position facing the channel 22, a positioning seat 52 is provided on the channel 22, the positioning seat 52 is connected to the rotating block 5 through a rotating shaft, the end of the block 4 exposed from the limiting groove 32 is provided with a connecting column head 1 41, the end of the rotating block 5 close to the connecting column head 1 41 is provided with a connecting column head 2 51, and the connecting column head 1 41 and the connecting column head 2 51 are connected through a connecting structure. The setting of the connecting structure has a traction effect on the block 4, which can prevent the block 4 from falling off.
[0026] like Figure 4 , Figure 5 As shown, the connection structure includes a reset spring 6 connecting the connecting column head 1 41 and the connecting column head 2 51. When the connection between the block 4 and the limiting groove 22 is released and the linkage support 2 and the connecting sleeve 21 are controlled to move, the block 4 and the connecting column head 1 41 move, and the reset spring 6 responds with a deformation, so that the block 4 can adjust the distance with the rotating block 5, and the distribution angle of the block 4 can be tilted until it smoothly disengages from the fiber groove 22, so as to facilitate the control of the linkage support 2 and the connecting sleeve 21 to move to the specified position, and then connect with the limiting groove 22 adapted to the position again, thereby improving the portability of the position adjustment work of the current transformer alarm 1, and having the advantage of being easy to operate manually.
[0027] Under the connecting action of the reset spring 6 , the rotating block 5 always exerts a certain tensioning force on the clamping block 4 , which effectively ensures the tightness of the connection between the clamping block 4 and the limiting groove 22 , and improves the accuracy of the clamping block 4 and the limiting groove 22 .
[0028] like Figure 4 , Figure 5 As shown, the connection structure also includes a guide bracket 7 arranged on the connecting column head 1 41, and a limiting plate 8 is arranged on the connecting column head 2 51. The limiting plate 8 is inserted into the inner side of the guide bracket 7. When the clamping block 4 and the connecting column head 1 41 swing, the guide bracket 7 is located outside the limiting plate 8 and rotates. The connection between the guide bracket 7 and the limiting plate 8 limits the swinging direction of the guide bracket 7, which can prevent the clamping block 4, the connecting column head 1 41 and the guide bracket 7 from deflecting and shaking, and further improves the tightness of the connection between the clamping block 4 and the limiting groove 22.
[0029] like Figure 4 As shown, in order to improve the smoothness of the movement of the connecting sleeve 21, an extension seat 9 is provided on the connecting sleeve 21 without a block 4, and the extension seats 9 are symmetrically arranged on both sides of the channel 22, and a roller group 10 is provided on the extension seat 9. When the connecting sleeve 21 moves along the distribution direction of the extension column 31, the roller group 10 rolls in contact with the extension column 31 to reduce friction resistance, thereby achieving the purpose of improving the smoothness of the movement of the connecting sleeve 21.
[0030] like Figure 2 As shown, in order to prevent the connecting sleeve 21 from being separated from the extension column 31, an interception ring 33 is provided at one end of the extension column 31 away from the mounting seat 3 to maintain the stability of the connecting sleeve 21, the linkage bracket 2 and the current transformer 1.
[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
