Problems solved by technology

Although the Chinese patent "A Multifunctional Sensor" (application number: 2018211415312) adopts the method of rotating and piercing the wire, the spiral electric needle used is still a common needle-like structure, which is essentially the same as the above-mentioned technology
[0006] 1) Using external pressure, the conductive metal thorns and the inner core of the wire are prone to bumping, the contact effect becomes poor, and the wire and the tip of the conductive metal thorn are easy to be damaged; if the outer skin of the wire is hard, especially to ensure the connection effect, use If there are multiple metal thorns or sawtooths, a lot of external force needs to be applied, the effect of breaking the skin is not good, the efficiency of breaking the skin is low, and it may cause damage to the entire power take-off mechanism;
[0007] 2) The operation of the open-close structure is relatively complicated, easy to damage, and has poor adaptability to wires of different diameters;
[0008] 3) There is no protection for the broken skin of the wire, especially when multiple metal thorns or sawtooth methods are used for a large broken skin. During long-term operation, the wire conductor at the broken skin is easily oxidized or corroded by the environment, resulting in data collection. The error is large, which may even cause the heat of the wire to cause the failure of the connected equipment and affect the production;
[0009] 4) The resistance of the voltage transformer is fixed, and the measurement range is small. If the voltage of different levels is measured, the transformer needs to be reselected, which will increase the cost in a disguised form, and the economy is poor;
[0010] 5) Without wire centering and fixed structure, the object to be tested is easy to move or roll, easy to puncture deviation, difficult to operate, and poor electrical contact stability
The patent does not explain the role of the toothed belt and the teeth, but from its structural analysis, a puncture needle is fixed in the middle of the inner ring of the lower body, and the puncture needle must be much higher than the toothed belt in order to pierce the wire reliably. The belt is not able to prevent wire rolling or stab deflection

Abstract

The invention provides a quick-assembling type voltage sensor applied to intelligent electric appliances and capable of realizing hot-line work, and belongs to the technical field of intelligent electrical equipment. The voltage sensor comprises a U-shaped structure, a conductor frame, an S-shaped power-taking pin, a voltage transformer, a current limiting resistor box, a pressing plate, an insulating gasket and the like. The voltage transformer, the current limiting resistor box and the conductor frame are integrally packaged, field operation is simplified, and rapid live loading and unloadingareachieved. Skin-breaking power-taking efficiency is improved by design of the S-shaped power-taking pin, a wire can be well fixed during skin-breaking power taking by ladder-shaped or wolf toothdesign, and a skin-breaking opening of the wire is protected by the designed insulating gasket. The current limiting resistor box enables the voltage transformer to adapt to conductors with different voltage levels. Integration, miniaturization, compatibility, convenience, flexibility, reliability and safety of the sensors required by intelligent electrical appliances are achieved. The whole sensor has simple structure, low cost and small size, and can be widely applied to intelligent monitoring of various wire voltage parameters.
