Abstract

The invention relates to a wireless passive real-time temperature measuring sensing apparatus, system, and method for a cable joint. The apparatus comprises a temperature sensor and an antenna that are buried into a cable joint by an epoxy resin injection curing molding process. The temperature sensor is in contact with a wire in the cable joint; and the antenna is fixed on the temperature sensor and is communication connection with the temperature sensor. According to the invention, because the temperature sensor and the antenna are buried into the cable joint by the epoxy resin injection curing molding process and the temperature sensor is in contact with the high-voltage end of the cable joint directly, the temperature sensor can measure the temperature of the high-voltage end of the cable joint effectively and accurately, so that a problem of inaccurate temperature measurement due to temperature differential complementing can be solved. The temperature sensor is buried into the cable joint by the epoxy resin injection curing molding process, post maintenance is avoided; and with the antenna, a problem of weak signal transmission of the temperature sensor because of thick epoxy resin can be solved.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a device and method for real-time monitoring of the temperature of a conductor inside a power cable joint through a wireless passive contact method. Background technique [0002] Most of the safety accidents in the power distribution industry of my country's power system are caused by the heating of the connection points in the cabinet. Therefore, if you want to avoid and reduce the occurrence of safety accidents, it is mainly to know the temperature change and temperature value of the connection point in advance. However, the existing temperature measurement methods, whether it is active wired non-contact or passive wired contact There are many problems in the formula. For example, when measuring temperature, the sensor is disturbed by the surrounding environment and electromagnetic field, the temperature measuring device is large, the sensor is fragile and easy to brea...
