Insulator with temperature monitoring function

Abstract

The invention relates to an insulator with a temperature monitoring function and aims at providing an insulator which is simple in structure, reliable in performance, convenient to manufacture and low in manufacture cost and has the temperature monitoring function. The technical scheme is that the insulator with the temperature monitoring function is provided with an insulator and an electric conduction metal strip arranged on the insulator and electrically connected with a device, and the temperature of the device needs to be measured. The insulator is characterized in that a heat conductinginsulation strip embedded inside the insulator is connected with the other end of the electric conduction strip, a temperature measuring device is arranged at a non-electric end of the heat conducting insulation strip, and the temperature measuring device is led to the outside of the insulator through a temperature measuring line at the non-electric end. The insulator is applicable to electric equipment with insulators or insulation sleeves in the electric engineering field.

Description

technical field [0001] The invention relates to an insulator with temperature monitoring function. Suitable for electrical equipment with insulators or insulating bushings in the electrical field. Background technique [0002] Insulators (or bushings) are generally made of solid insulating materials and are installed between conductors of different potentials or between conductors and grounding components. They are devices that simultaneously perform electrical insulation and mechanical support. Although the structure and shape of different types of insulators are quite different, they are all composed of insulators and metal components. Electrical equipment in substations, such as transformers, circuit breakers, voltage transformers, current transformers, lightning arresters, and isolation switches, have components such as porcelain sleeves and rod-shaped pillars. Devices such as sleeves and rod-shaped pillars are also collectively referred to as insulators. [0003] At ...

AI Technical Summary

Problems solved by technology

[0004] Among the existing monitoring technologies, such as: 1. Using the wireless network plus sensor method, because the sensor network should be installed on the equipment, and the power supply is mostly powered by batteries, and the service life is generally not more than two years, so it cannot work for a long time. Expired maintenance increases capital investment

2. Using infrared thermometers to measure temperature manually is random, and the workload is heavy, so it is impossible to work online in real time for a long time

3. For example, the Chinese patent No. 2011101386-176-1.3 discloses a "production method of an insulator or contact box with a temperature or / and voltage sensor", which uses optical fibers to fully embed the insulator, although the effect is better, However, due to the high manufacturing cost of practical optical fiber sensors, it cannot be popularized and used in large quantities.
