Temperature measurement and control type T-shaped insulating sheath

Abstract

The invention relates to a temperature measurement and control type T-shaped insulating sheath and belongs to the technical field of coatings. The insulating sheath comprises a flame-retardant sheath;a threaded groove is formed in the flame-retardant sheath; a cooling pipe is embedded in the threaded groove, and cooling liquid is contained in the cooling pipe; a communication module and a wireless temperature sensor which are connected with each other are arranged on the flame-retardant sheath; the communication module transmits the temperature measured by the wireless temperature sensor to the early warning system; the early warning system is used for receiving the transmitted temperature data, comparing the temperature data with a preset temperature threshold value, and giving an alarmwhen the temperature data exceeds the threshold value; the early warning system is also connected with the signal transceiving system and is used for sending the temperature data received by the earlywarning system and a comparison result to a background; and the background also sets a preset temperature threshold in the early warning system through the signal transceiving system. According to the insulating sheath, the temperature of the insulating sheath can be effectively reduced, abnormal temperature can be found in time, the possibility of equipment burnout is reduced, and operation stability of a power grid is ensured.

Description

technical field [0001] The invention belongs to the technical field of cable connection devices for ring network cabinets, and in particular relates to a temperature-measuring and temperature-controlling T-shaped insulating sheath. Background technique [0002] The T-type insulation reinforced sheath is an important prefabricated part of the T-type connector of the 10kV ring network cabinet cable. Its function is to enhance the phase-to-phase and ground insulation of the high-voltage live conductors and prevent the high-voltage live conductors from being directly exposed to the air. On the contrary, the airtight feature of this part also makes it difficult to detect the abnormal state generated during use. When a partial discharge fault or internal overheating occurs, the operation and maintenance personnel will notice it too late, which will cause parts to burn out and leak electricity, damage the bushing and even cause a fire. Because the cable T-connector has the charact...

On the contrary, the airtight feature of this part also makes it difficult to detect the abnormal state during use

When a partial discharge fault or internal overheating occurs, the operation and maintenance personnel will notice it too late, which will cause parts to burn out and leak electricity, damage the bushing and even cause a fire

Because the cable T-type connector has the characteristics of fully enclosed, insulated and heat-insulated, and low heat conduction rate, the traditional contact operation state cannot effectively measure accurate temperature
