Problems solved by technology

[0003]However, the temperature and pressure in the combustion chamber of the gas turbine are very high, and the conventional lead base generally leads the lead wire out along the axis of the lead base, but with this structure The lead base leads, high temperature and high pressure gas can easily blow off the sealant, resulting in the leakage of high temperature and high pressure gas through the lead base, which has a great impact on the reliability and safety of the test

Abstract

The invention relates to a wire leading device and gas turbine test equipment. The wire leading device comprises a guide rod (10) and a wire leading seat (20); the guide rod (10) is arranged in a wire leading hole formed in equipment to be subjected to wire leading; the guide rod (10) is provided with a first through hole (11); the first through hole (11) is parallel to the axis direction of the wire leading hole; the wire leading seat (20) is connected with the guide rod (10); the wire leading seat (20) is provided with a second through hole (21) and a wire leading groove (22) communicated with the second through hole (21); the second through hole (21) is parallel to the axis direction of the wire leading hole; the wire leading groove (22) is formed in the side face, away from the guide rod (10), of the wire leading seat (20); and the wire leading groove (22) is configured to guide a lead to be led in the direction deviating from the axis direction of the second through hole (21). The gas turbine test equipment comprises the wire leading device. The wire leading device can reduce the possibility that high-temperature and high-pressure gas directly blows out a sealant, and is good in sealing performance and high in reliability.

Description

technical field [0001] The invention relates to the technical field of gas turbines, in particular to a lead wire device and gas turbine testing equipment. Background technique [0002] In the process of testing the gas turbine, in order to monitor the internal pressure, temperature and other working parameters of the gas turbine, it is often necessary to open holes in the combustion chamber casing and other components, and install the test lead base to lead the test lead out from the casing , then seal by pouring sealant inside the leadblock. [0003] However, the temperature and pressure in the combustion chamber of the gas turbine are very high. The conventional lead base generally leads the lead wire out along the axis direction of the lead base. As a result, high-temperature and high-pressure gas leaks through the lead base, which greatly affects the reliability and safety of the test. [0004] It should be noted that the information disclosed in the background techno...
