Problems solved by technology

[0002] During the operation of the distribution box station, it is impossible to perform periodic inspections, lack of monitoring means, and cannot obtain the environmental status of the distribution box station in real time. When the temperature in the distribution box station is abnormal, it is impossible to provide early warning prompts
Moreover, the temperature of the electrical connection parts and joints in the distribution box station will rise due to the manufacturing process, aging operation or increase in contact resistance. If it is not handled in time, it will cause the equipment to burn out and cause a power outage in the distribution box station. the occurrence of the accident

Abstract

The invention provides a cylindrical switch cabinet and a passive temperature measuring device for buried cable joints. A wireless transmission module, an induction circuit and a temperature measurement sensor are installed in the cylindrical shell, a radio frequency device is installed on one side of the induction circuit and the temperature measurement sensor, an antenna is installed on the cylindrical shell, and buckles are respectively fixed on both sides of the upper part of the cylindrical shell , the buckle is a metal elastic hook. The invention is set on the cable, and can perform passive temperature measurement of the switch cabinet and the buried cable joint, thus saving time for temperature measurement, reducing labor, and realizing automatic temperature measurement. The temperature measurement can be transmitted through the antenna and received through the wireless network. Record and over-temperature alarm. It is suitable for use as a passive temperature measuring device for switch cabinets and buried cable joints.

Description

technical field [0001] The utility patent relates to a temperature measuring device applied to a cable joint in a switch cabinet of a power distribution box station in the electrical field, specifically a passive temperature measuring device for a cylindrical switch cabinet and an underground cable joint. Background technique [0002] During the operation of the distribution box station, it is impossible to do periodic inspections, lack of monitoring means, and cannot obtain the environmental status of the distribution box station in real time. When the temperature in the distribution box station is abnormal, it is impossible to give an early warning. Moreover, the temperature of the electrical connection parts and joints in the distribution box station will rise due to the manufacturing process, aging operation or increase in contact resistance. If it is not handled in time, it will cause the equipment to burn out and cause a power outage in the distribution box station. Ac...
