[0041] Such as figure 1 As shown, the current mutual induction module 1 and the analog-to-digital conversion module 4 of the embodiment of the present invention are all packaged in the metal casing 3, and the current mutual induction module 1 is used to detect currents of various frequencies; the analog-to-digital conversion module 4 is connected with each current transformer It is connected with the host computer signal, and is used to convert the current analog signal detected by the current mutual sensing module 1 into a digital signal and then send it to the host computer; the temperature sensor 2 is installed on the o...

Embodiment 2

[0076] An embodiment of the present invention provides an application method of a multifunctional sensor, based on the multifunctional sensor of Embodiment 1, such as Figure 12 As shown, the application methods include:

[0077] Step S1: The current mutual sensing module detects the power frequency current at the current moment in real time, and the temperature sensor detects the temperature of the area to be measured at the current moment in real time.

[0078] Step S2: The host computer compares the obtained power frequency current at the current moment and the temperature of the area to be measured at the current moment with the historical data.

[0079] Step S3: If the temperature of the region to be measured at the current moment is higher than the highest temperature in the historical data, compare the power frequency current corresponding to the highest temperature with the power frequency current at the current moment.

[0080]Step S4: If the power frequency current ...

Abstract

The invention discloses a multifunctional sensor and an application method thereof. The sensor comprises a current mutual inductance module and an analog-to-digital conversion module which are packaged in a metal housing, and the current mutual inductance module is used for detecting currents of various frequencies; theanalog-to-digital conversion module is in signal connection with each current transformer and an upper computer, and is used for converting the current analog signal detected by the current transformer module into a digital signal and sending the digital signal to the upper computer; and a temperature sensor is mounted outside the metal shell, is in signal connection with the upper computer, and is used for testing the temperature of the to-be-tested area and sending the temperature to the upper computer. Detection of current and temperature of different frequencies is realized by integrating various detection modules into the same equipment; and the problems that in the prior art, when multiple sensors are independently installed, the size is too large, and installation is difficult are solved.

Description

technical field [0001] The invention relates to the field of electric equipment sensing, in particular to a multifunctional sensor. Background technique [0002] Cable has gradually become the main channel of power transmission system in urban areas, which has the characteristics of small footprint and beautiful appearance. During the operation of the cable, there may be problems such as insulation defects caused by poor manufacturing process or external force damage, and grounding defects caused by negligent construction. When there is a cross-connection error in the cable, the power frequency current on the grounding bar in the grounding box will increase significantly, which can be measured by a power frequency current transformer; when there is an insulation defect, there will be an obvious high frequency current on the grounding bar, It can be measured by a high-frequency current sensor; when there is a high-resistance grounding fault in the cable, the protector in the...
