Description

Technical Field

[0001] The utility model relates to the technical field of inflatable cabinet detection, in particular to a sealable temperature measuring line adapter. Background Art

[0002] At present, with the rapid development of subways and high-speed railways in my country, the power system has continuously improved its requirements for high reliability, low maintenance and miniaturization of power equipment. The domestic inflatable cabinet technology has developed rapidly, and the products have been put into use in large quantities in all walks of life. Since the primary wiring part of the inflatable cabinet is sealed in the inflatable compartment, compared with ordinary switch cabinets, the heat is too concentrated during operation and the heat dissipation environment is poor. If the greenhouse is too high, it will directly affect the safe and stable operation of the equipment. If it is not controlled, the overheating will continue to accumulate, which will deteriorate the performance of the insulation components inside, and even cause breakdown and accidents. Therefore, temperature rise control should be an important part of structural design and production.

[0003] The temperature measuring device in the prior art has insufficient sealing of the connection line with the gas box of the inflatable cabinet, which will cause gas to escape and affect the temperature measurement accuracy. In addition, since there are many temperature rise lines during temperature measurement, the temperature rise lines often fall off or get entangled, causing inconvenience to subsequent maintenance.
