Problems solved by technology

[0005] After the ring network cabinet has been in operation for a long time, it is difficult to block the radiation of sunlight, and there is an over-sealed condition inside the ring network cabinet, which will affect the heat dissipation effect of the ring network cabinet equipment, causing heat accumulation inside the machine and temperature rise. high conditions, eventually damaging electrical equipment
In the case of large temperature changes, if the current humidity is high, even if the staff installed the infrared thermometer in the ring network cabinet in advance to monitor the internal temperature of the ring network cabinet, it

Abstract

The invention discloses a temperature sensing device and a ring main unit temperature monitoring system. The invention relates to the technical field of ring main unit cable temperature monitoring. The temperature sensing device comprises a fixed outer shell and a hoop fixedly connected with the fixed outer shell. An FRID label and a base are arranged in the fixed outer shell, the base seals the FRID label in the fixed outer shell, an FRID temperature measuring chip used for temperature detection is arranged on the FRID label, and the base is located in the side, close to the hoop, of the fixed outer shell. According to the invention, a wireless passive temperature sensor is fixed to the sleeve through the hoop to monitor the temperature in the ring main unit in real time; and through arrangement of an alarm, when the temperature exceeds a preset temperature value, the alarm gives an alarm to prompt a manager to carry out cooling, so that the problem of ring main unit damage or fire accidents caused by internal temperature rise of the ring main unit is solved in time, and the damage probability of ring main unit equipment is remarkably reduced.

Description

technical field [0001] The present application relates to the technical field of ring network cabinet cables, in particular to a temperature sensing device and a ring network cabinet temperature monitoring system. Background technique [0002] The ring network cabinet is a group of electrical equipment for transmission and distribution that is installed in a metal or non-metal insulated cabinet or made into an assembled interval ring network power supply unit. Its core part uses load switches and fuses. It has simple structure, small size, It has the advantages of low price, improved power supply parameters and performance, and power supply security. [0003] As a wireless transmission technology, RFID technology has expanded its application of radio frequency identification tags from just transmitting data stored in tags to indicate its identity to more and more application fields. For example, when transmitting the data representing the identity, the ambient temperature d...
