Problems solved by technology

But also there are following deficiencies, (1) the sensing part is fixed on the surface of the transmission wire by the U-shaped clip. On the one hand, the transmission wire may not be fixed firmly due to the lack of effective support; The non-movability of the transmission wire makes it inconvenient to pass through; (2) The U-shaped clip is bonded to the metal layer through an adhesive, and the pasted part of the metal layer may not generate induced charges, which will cause the metal layer Waste; and by changing the height of the U-shaped clip to adjust the distance between the sensing part and the transmission wire, the U-shaped clip may not be effectively fixed at a specific position due to the lack of a fixed structure

Embodiment 1

[0031]The current and voltage integrated sensor can detect the current signal and voltage signal of the AC distribution network at the same time. Among them, the working principle of the current sensor 3 is Faraday's law of electromagnetic induction. The alternating magnetic field generated by the AC signal in the transmission wire 5 passes through the magnetic core coil 9 to generate an induced electromotive force at both ends of the magnetic core coil 9, and the electromotive force is proportional to the measured current. , the magnitude of the measured current can be obtained through the electromotive force; the working principle of the voltage sensor 4 is the principle of electrostatic induction. The distance between the two metal layers 12 and the transmission wire 5 is different, and the number of induced charges is different. The difference between the induced charges can be used to obtain the alternating electric field generated by the transmission wire 5, and then the ...

Embodiment 2

[0041] like Figure 5 As shown in 9 or 10, the difference between the second embodiment and the first embodiment is that the front and rear adjustment mechanisms on both sides of the first sensing part 1 and the second sensing part 2 include a gear adjustment mechanism 7 and a spring adjustment mechanism 13 , and the spring adjustment mechanism 13 includes a third telescopic rod 131, a fourth telescopic rod 132, a second adjusting rod 133 and a second push block 134, the third telescopic rod 131 and the fourth telescopic rod 132 are respectively fixedly installed on the The side wall of the metal layer 12 and the second adjusting rod 133 are fixedly installed on the outer walls of the third telescopic rod 131 and the fourth telescopic rod 132 , and a second space is opened inside the second adjusting rod 133 . The cavity 136, the sliding connection end of the second cavity 136 is provided with the movable rod 137 of the handle 142, one end of the movable rod 137 is elastically...

Abstract

The invention provides a current and voltage integrated sensor which comprises a first sensing part and a second sensing part, a first distance adjusting device and a second distance adjusting device are movably installed between the first sensing part and the second sensing part, and a transmission wire is arranged between the first distance adjusting device and the second distance adjusting device in a penetrating mode. The distances between the two voltage sensors and the transmission wire are different, the first distance adjusting device and the second distance adjusting device comprise an up-down adjusting mechanism and a front-back adjusting mechanism, the up-down adjusting mechanism is used for adjusting the distances between the two voltage sensors and the transmission wire, and the front-back adjusting mechanism is used for adjusting the distances between the two voltage sensors and the transmission wire. The front-back adjusting mechanism is used for adjusting the distance between the first distance adjusting device and the transmission wire. The distance between the two voltage sensors and the transmission wire can be adjusted, waste of metal materials due to the fact that fixing pieces are pasted on the surface of a metal layer is avoided, and the transmission wire can be better clamped and fixed.

Description

technical field [0001] The invention relates to the technical field of current and voltage integration, in particular to a current and voltage integrated sensor. Background technique [0002] Current sensors and voltage sensors are important devices for realizing online status monitoring of power systems. Its accuracy and reliability are closely related to the safe and reliable operation of the power system. There are many studies on current and voltage sensors in the prior art, such as a passive current and voltage integrated sensor with application publication number CN106018917B. The passive current and voltage integrated sensor does not require external power supply by using passive measurement. Low power consumption, with voltage sensor and current sensor at the same time, can detect the current signal and voltage signal of the transmission wire at the same time, no need to use two sets of equipment to detect voltage and current separately, convenient detection, save t...
