Description

Technical Field

[0001] The utility model relates to a temperature measuring device for a working device in a high-voltage equipment cabinet used in a power system, in particular to a quick-access temperature inspection trolley for a high-voltage equipment cabinet. Background Technique

[0002] As the society's requirements for the working reliability and safety of the power system are getting higher and higher, the temperature measurement of the working device in the high-voltage equipment cabinet used in the power system has become an ordinary task for equipment manufacturers. By measuring the temperature, it is possible to detect the temperature rise of the high-voltage equipment cabinet during operation, so as to evaluate the thermal stability and heat resistance of the high-voltage equipment cabinet and determine whether it meets the technical requirements. Generally, equipment manufacturers use desktop temperature inspection instruments to measure the temperature of the working device in the high-voltage equipment cabinet. When in use, several temperature measurement wires are used. The temperature sensors of the temperature measurement wires are respectively set and fixed to the measurement parts in the high-voltage equipment cabinet, and the outer ends of the temperature measurement wires are respectively connected to each pair of rotary pressure-type input knobs on the back of the temperature inspection instrument. Since the connection is relatively cumbersome, the measurement efficiency is low, and poor connection is likely to occur, affecting the measurement effect. Moreover, when measuring a high-voltage equipment cabinet, multiple temperature measurement wires are often required at the same time. When measuring, it is necessary to carry the temperature inspection instrument and many temperature measurement wires at the same time, causing a lot of inconvenience to the temperature measurement work.

[0003] An intelligent mobile temperature field inspection trolley disclosed in Chinese Patent No. CN216433294U has a structure including a vehicle body. A plurality of telescopic rods that can rotate are installed on the top of the vehicle body. A temperature probe is installed at one end of the telescopic rod away from the vehicle body. A plurality of walking wheels are installed at the bottom of the vehicle body. A controller for controlling the temperature probe is also installed inside the vehicle body. The disadvantage of this solution is that the temperature probe cannot be set inside the high-voltage equipment cabinet, so it is not applicable to the temperature measurement inside the high-voltage equipment cabinet used in the power system.

[0004] An automatic inspection and temperature measurement device for a substation disclosed in Chinese Patent No. CN203616007U includes a guide rail mechanism erected around the high-voltage equipment in the substation. A four-wheel trolley is arranged on the guide rail mechanism. An omnidirectional rotating cloud platform is arranged on the four-wheel trolley. An infrared imager is arranged on the cloud platform. A protective cover is arranged on the four-wheel trolley. The movement of the four-wheel trolley and the cloud platform is controlled by a DSP. Temperature acquisition, storage and wireless transmission are completed by a single-chip microcomputer. The DSP and the single-chip microcomputer communicate with each other. The four-wheel trolley has a charging function, and a power receiving end is arranged on the charging trolley. The disadvantage of this solution is that the infrared imager also cannot be set inside the high-voltage equipment cabinet, so it is not applicable to the temperature measurement inside the high-voltage equipment cabinet used in the power system.
