Technical Field

[0001] The utility model relates to the technical field of smart electric meters, and more specifically to a short-circuit-proof smart electric meter. Background Art

[0002] With the continuous development of power engineering and the upgrading of smart grid systems, in order to facilitate people's daily lives, short-circuit-proof smart meters have gradually replaced traditional meters. Compared with traditional meters, smart meters are fully electronic and have higher accuracy. Through the two-way transmission of information, the real-time data of the meter can be uploaded to the energy grid system for processing, eliminating the tedious and complicated meter reading work of traditional meters.

[0003] However, the existing short-circuit-proof smart meters need to be connected to the network to realize remote monitoring and management functions. If the power supply is unstable or a power outage occurs, it may affect its normal operation. In addition, most of the existing short-circuit-proof smart meters do not have the function of dust and moisture prevention. Therefore, when working for a long time in a humid environment, the internal electronic devices are prone to moisture and short circuit, and it is very inconvenient when disassembly for maintenance is required.

[0022] Reference Figure 3 As shown, the outer shell 1 is provided with a circular installation groove 101 at the position where the electric meter display screen 2 is provided, circular through holes 102 are provided on both sides of the surface of the outer shell 1 near the top, an outer shell cavity 103 is provided inside the outer shell 1, and circular holes 104 are provided at the position of the line installation tube 7 at the top of the line installation box 5 provided at the top of the outer shell 1, and the circular holes 104 are convenient for connecting the lines.

[0023] Reference Figure 4As shown, the drying box 4 includes a moisture-proof box 401, a rectangular cavity 402 is opened inside the moisture-proof box 401, ventilation holes 403 are opened on both sides of the surface of the moisture-proof box 401, and neatly arranged solid desiccants 404 are opened inside the rectangular cavity 402, which is conducive to absorbing moisture in the air.

[0024] Reference Figure 5 As shown, a backup power supply 8 is fixedly connected to the side of the line installation box 5 away from the meter display screen 2, a rectangular inner cavity 501 is opened inside the line installation box 5, a cylindrical rod 9 is fixedly connected to the side of the line installation box 5 close to the backup power supply 8, an electromagnetic block 10 is opened on the surface of the cylindrical rod 9 near the top, a magnetic ring 11 is movably sleeved on the surface of the cylindrical rod 9 at the bottom of the opened electromagnetic block 10, a power switch 12 is opened inside the line installation box 5 at the bottom of the magnetic ring 11, and a line fixing box 13 is opened on the side of the line installation box 5 away from the cylindrical rod 9. The backup power supply 8 is helpful to keep the meter in normal operation when the voltage is unstable or there is a power outage.

[0025] Reference Figure 6 As shown, an installation cavity 1301 is opened inside the line fixing box 13, and the pull rod 6 is located in the installation cavity 1301 opened in the line fixing box 13. A spring 14 is movably sleeved on the inner surface thereof, and an anti-short circuit blocking plate 15 is opened at a position adjacent to the line installation tube 7 opened in the installation cavity 1301. The anti-short circuit blocking plate 15 is helpful to block the line to prevent short circuit caused by line contact.

[0026] The working principle of the utility model is as follows: first, when using, the corresponding line is inserted into the line installation tube 7 through the circular hole 104 opened in the outer shell 1, and then the pull rod 6 close to one side of the line installation tube 7 is pulled respectively so that the pull rod 6 is squeezed by the spring 14 sleeved on the surface, and then the line is continued to be pushed forward so that the line reaches the inside of the electric meter through the line installation tube 7, and then the pull on the pull rod 6 is released so that the spring 14 drives the pull rod 6 to reset, and at this time, the end of the pull rod 6 close to the line installation tube 7 pushes the line to the anti-short circuit blocking plate 15 for fixing, and then the line is blocked by the anti-short circuit blocking plate 15 to prevent the line contact from causing a short circuit, and then when the voltage is unstable or the power is off, the circular The electromagnetic block 10 opened on the surface of the pole 9 loses its magnetism due to power outage. At this time, the electromagnetic block 10 stops adsorbing the magnetic ring 11, so that the magnetic ring 11 drops due to gravity and triggers the power switch 12 at the bottom of the rectangular inner cavity 501 opened in the line installation box 5. At this time, the power switch 12 turns on the backup power supply 8 to power the electric meter. Then, when the electric meter is in normal use, the external air enters the inner cavity 103 of the outer shell 1 through the heat dissipation hole groove 3 opened in the outer shell 1. At this time, the moisture in the air enters through the air permeable hole groove 403 opened in the moisture-proof box 401, so that the moisture in the air is adsorbed by the solid desiccant 404, thereby preventing the moisture in the air from causing the internal components of the electric meter to become damp and short-circuited.

[0027] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
