Abstract
Description
Technical Field
[0001] The utility model belongs to an electric power measuring tool, in particular to an adapter device for an insulating rod with variable length and a common clamp meter. Background Art
[0002] Electricity theft refers to users using various illegal means to bypass or damage the electricity metering device of the power supply company in order to pay less or no electricity bills. Electricity theft not only damages the legitimate rights and interests of power supply companies, but also undermines fair competition in the electricity market, and may also cause damage to power facilities and safety hazards. The current mainstream electricity theft methods include modifying the energy meter and bypassing the energy meter. Among all the electricity theft schemes, meter theft is a common electricity theft method. It uses some special devices or means to change the normal wiring or working state of the energy meter, without tampering with the electricity meter itself, so that the current coil or voltage coil of the energy meter loses pressure or undervoltage, or changes the phase relationship between current and voltage, so that the energy meter slows down, stops or reverses. The electricity theft method of bypassing the meter to achieve diversion has become a mainstream electricity theft method due to its economy and concealment. Various monitoring methods for electricity theft have also emerged. Once the electricity theft occurs, the electricity metering device must give feedback on the data difference somewhere. The use of the electricity metering device to record and monitor the data provides us with the feasibility of judging electricity theft. Therefore, the data of smart meters on the user side can be used to verify the voltage, current, node power and other additional measurement data in the power grid. Based on the above analysis, it can be seen that in power measurement work, clamp meters are often needed to measure current.
[0003] However, traditional clamp meters usually need to be operated by hand, which is very inconvenient in some high-altitude or narrow occasions. In addition, there are certain safety risks in hand-held operation. Insulating rods and clamp meters are commonly used tools in the field of electrical measurement. Insulating rods are used to provide electrical insulation to protect the safety of operators when measuring in live environments. Clamp meters are used to measure electrical parameters such as current and voltage. Traditional insulating rods usually have a fixed length, which may limit their use in certain specific scenarios or space-constrained situations. For example, in some narrow spaces or high places, insulating rods of fixed length may not be able to reach the target measurement position, making measurement difficult or impossible. In addition, ordinary clamp meters may require special transfer devices or adapters when used with insulating rods, which increases the complexity and cost of operation. Moreover, clamp meters of different models or brands may require specific adaptation methods, limiting flexibility and versatility. Utility Model Content

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.
[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the adapter device of the variable-length insulating rod and the ordinary clamp meter in this embodiment includes a fixing seat 1 for mounting and fixing the clamp meter 4, and the lower end of the fixing seat 1 is provided with a movable connecting part 2 for connecting with the insulating rod 3 of required length or adjustable length, and the fixing seat 1 is also provided with a guide rail 5, and the guide rail 5 is provided with a U-shaped fixing frame 6 that can slide along the guide rail 5 and an electric push rod 7 for driving the U-shaped fixing frame 6. The clamp meter 4 is installed in the groove of the U-shaped fixing frame 6 to control the button switch 41 on the side of the clamp meter 4 to open or close the clamp arm 42 on the clamp meter 4 by sliding the U-shaped fixing frame 6, so as to ensure the efficiency of the power measurement work and improve the safety.
[0027] like Figure 1 and Figure 2 As shown, in order to facilitate the control of the electric push rod 7, a control switch 72 is connected to the power supply cable 71 of the electric push rod 7 in this embodiment, and an electrical connector for connecting to a power source is provided at the end of the power supply cable 71.
[0028] like Figure 2 As shown, in this embodiment, the fixing base 1 is composed of a front bracket 11 and a rear bracket 12 connected to each other, a mounting groove 10 is formed between the front bracket 11 and the rear bracket 12, and a back plate 13 extending upward is provided on the top of the rear bracket 12. The clamp meter 4 is inserted into the mounting groove 10, and the guide rail 5 is installed and fixed on the back plate 13, so as to achieve compatibility with clamp meters 4 of different manufacturers and specifications.
[0029] like Figure 2 As shown, in this embodiment, the front bracket 11 and the rear bracket 12 both include a connecting plate and baffles located at both ends of the connecting plate and bent to the same side, and the baffles of the front bracket 11 and the rear bracket 12 are connected and fixed to each other through connecting parts. The fixing seat 1 of this structure is light in structure, easy to process, and has a low processing cost.
[0030] In order to ensure the stability of the clamp meter 4, as an optional implementation, the clamp meter 4 can also be fixed to the back plate 13 through a connector or a snap connection to prevent the clamp meter 4 and the fixing base 1 from sliding up and down.
[0031] In this embodiment, the U-shaped fixing frame 6 includes a connecting plate and baffles located at both ends of the connecting plate and bent to the same side, so that a groove for arranging the clamp meter 4 is formed between the connecting plate and the baffles located at both ends of the connecting plate. The baffle on one side can be used to control the button switch 41 on the side of the clamp meter 4 to open or close the clamp arm 42 on the clamp meter 4. When the U-shaped fixing frame 6 slides to one end, the baffle squeezes the button switch 41 on the side of the clamp meter 4 to open the clamp arm 42 on the clamp meter 4; when the U-shaped fixing frame 6 slides to the other end, the baffle disengages from squeezing the button switch 41 on the side of the clamp meter 4, so that the clamp arm 42 on the clamp meter 4 is closed, thereby realizing the control of the clamp arm 42 on the clamp meter 4. Since the clamp arm 42 on the clamp meter 4 is located on one side of the clamp meter 4, which is a standard design of the clamp meter 4, the above structure can achieve compatibility with clamp meters 4 of different manufacturers and specifications.
[0032] As an optional embodiment, the movable connection component 2 in this embodiment is a sleeve, which is fixedly connected to the lower end of the fixing seat 1, and the end of the insulating rod 3 is plugged into the sleeve, so that the connection between the two is firm and reliable. As an optional embodiment, radially arranged bolts can be provided on the sleeve to clamp the insulating rod 3 to make the connection more firm and reliable.
[0033] like Figure 2 As shown, in this embodiment, the guide rail 5 is provided with a mounting hole 51 arranged in the horizontal direction, one end of the electric push rod 7 is installed in the mounting hole 51, and the other end is movably connected to the U-shaped fixing frame 6, so that the connection structure between the guide rail 5 and the U-shaped fixing frame 6 is more compact and small.
[0034] The insulating rod 3 can be made of required insulating materials as required. For example, as an optional implementation, the insulating rod 3 in this embodiment is made of glass fiber reinforced plastic, which has the advantages of insulation, firmness, lightness, corrosion resistance, high temperature resistance, etc. In addition, the fixing seat 1 and the movable connecting part 2 in this embodiment are both made of insulating materials, which can avoid the secondary magnetic field formed by the eddy current generated by the metal during detection from interfering with the detection result of the clamp meter 4.
[0035] The working process of the variable-length insulating rod and ordinary clamp meter adapter device of this embodiment is as follows: The variable-length insulating rod and ordinary clamp meter adapter device of this embodiment is mainly used to read the current of the commonly used electric energy meter on the market. In the power measurement task, it is often inconvenient to directly hold the ordinary clamp meter for measurement, or the power measurement task needs to be performed in bad weather. The variable-length insulating rod and ordinary clamp meter adapter device of this embodiment can be adjusted according to the specific scene requirements. The indicating surface of the clamp meter 4 is facing up, and after adjusting or adopting the required or adjusting the length of the insulating rod 3, the control switch 72 is controlled to open the clamp arm 42 and slowly approach the electric energy meter, and then the jaws are aligned with the live wire to be measured, and the control switch 72 is controlled to tighten the clamp arm 42 to read the data. The variable-length insulating rod and ordinary clamp meter adapter device of this embodiment can adapt the insulating rod 3 of different lengths or adjustable lengths to the clamp meter 4, so that the clamp meter 4 can measure the current without holding it, which improves the convenience and safety of the measurement. At the same time, the insulating rods 3 of different or adjustable lengths can be suitable for measurement environments and task requirements at different heights and narrow occasions, which improves the convenience, flexibility and adaptability of power measurement operations while ensuring safety, thereby improving the work efficiency of power measurement.
