Intelligent electric integrated hot-line operation internet of things sensor

Abstract

The invention discloses an intelligent electric integrated hot-line operation internet of things sensor, and belongs to the technical field of the intelligent electric equipment. The sensor comprisesa current transformer, a voltage transformer, a temperature sensor, a spiral power-taking needle, a pressing plate, an insulation spacer, a baffle plate, a current-limiting resistance box, and an outgoing interface; the voltage sensor, the current sensor and the temperature sensor are integrated to lead out a signal in a unified manner, the field operation is simplified, and the hot-line dismounting is realized; the coat-breaking power-taking efficiency is improved through the design of the spiral power-taking needle, the baffle plate and recessed symmetric stepped structure can fix the conductor line well when performing coat-breaking and power-taking, the coat-breaking opening of the conductor line is protected through the insulation spacer, and the current-limiting resistance box can enable the sensor to adapt to conductor lines in different voltage levels. A convenient internet of things sensor is provided for realizing the big data collection of the intelligent electricity, and the sensor has the advantages of being simple in structure, hot-line in operation, convenient to use, low in cost, and convenient to dismount, and can be extensively applied to various electric equipment monitoring.

Problems solved by technology

However, some key technical problems have not been effectively resolved. For example, the voltage sampling puncture knife is still a multiple metal thorn-type piercing method, and the cable temperature monitoring element is in close contact with the root of the voltage sampling puncture knife. The monitoring components are directly in contact with strong electricity, which brings safety hazards, etc.

[0005] The Chinese patent "multifunctional puncture wire clip" (application number: 2018100079755) adopts the adjustment piece and the adjustment tooth to adapt to wires of different thicknesses, but the structure is very complicated; the lower surface of the shell and the upper surface of the clamping plate All are equipped with clamping grooves, which are convenient for the clamping plate and the shell to clamp and fix the external wires, but the adaptability to the thickness of the wires is not strong, especially when the wires are too thin
