Many irradiation tests of insulating materials are carried out at home and abroad, and in the irradiation test process, the real-time electrical property measurement of an insulating material irradiation sample cannot be carried out, so that the accumulated dose received when the insulating property of a newly developed insulating material fails under the irradiation condition cannot be monitored when the newly developed insulating material is subjected to the irradiation property test.

The sealing cover 18 may be made of radiation-resistant material, and a sealing gasket may be disposed between the sealing cover 18 and the barrel 12 to further improve the sealing performance therebetween. Advantageously, the interface assembly 16 may include an aircraft plug that may be sealingly disposed in a sealing cover 18.
The on-line monitoring irradiation experiment device 10 further comprises a flange 20 arranged at the end part of the cylinder body 12, and the sealing cover 18 is arranged on the flange 20. The flange 20 can be arranged flush with the end of the cylinder 12, whereby the sealing cap 18 can be arranged sealingly on the end side of the flange 20, so that together with the end of the cylinder 12 a sealing connection with the sealing cap 18 can be formed. Further, in order to facilitate the lifting and lowering operations of the on-line monitorable irradiation experiment device 10, a lifting handle 22 is provided on the flange 20, the lifting handle 22 can be connected or clamped by a lifting device to perform the lifting and lowering operations of the on-line monitorable irradiation experiment device 10, for example, after the on-line monitorable irradiation experiment device 10 is prepared, when the on-line monitorable irradiation experiment device 10 needs to be inserted into an irradiation hole of a reactor, the lifting handle 22 can be clamped by the lifting device and the lifting operation is performed, the on-line monitorable irradiation experiment device 10 is moved to a proper position, so that the bottom end of the on-line monitorable irradiation experiment device 10 is aligned with the opening of the irradiation hole, and then the lifting device is operated to enable the on-line monitorable irradiation. Further, the flange 20 may be provided with a positioning hole, and the on-line monitoring irradiation experiment apparatus 10 may be fixed in the irradiation hole by fixing members such as bolts, so as to prevent the on-line monitoring irradiation experiment apparatus 10 from shaking in the irradiation hole.
Further, the on-line monitorable irradiation experiment device 10 according to the present invention may include a support tube 24 disposed at the bottom of the cylinder 12, and the thermocouple 14 is disposed on the outer circumferential wall of the support tube 24. The support tube 24 may be disposed at the bottom of the bowl 12 by a base 26 of the bowl 12, and the base 26 may be a stainless steel plate that may be fixedly disposed at the bottom of the bowl 12 by an interference fit.

In order to improve the radiation resistance of the data lines and/or power lines accessed through the interface assembly 16, metal wires sleeved with ceramic beads are adopted in the parts of the data lines and/or power lines, which are positioned inside the cylinder 12. Namely, the continuous ceramic beads are sleeved outside the metal wire, and the metal wire inside is protected by the ceramic beads next to the metal wire, so that the radiation resistance of the data wire and/or the power wire is greatly improved, and the service life of the data wire and/or the power wire is greatly prolonged. In addition, the parts of the data lines, which are positioned outside the cylinder 12, adopt polyimide electromagnetic wires, and the polyimide wrapping provides good protection for the internal metal wires, which is beneficial to prolonging the service life of the data lines.

For example, single-pin, 10-pin, 20-pin, 50-pin and 80-pin aviation plugs can be used according to actual needs, and the aviation plugs are not limited to the types described above and can be selected according to specific needs. Therefore, the irradiation experimental device 10 capable of monitoring irradiation on line according to the invention can meet the test requirements of various samples and different parameters, greatly expands the application range of the experimental device, and improves the test efficiency of the experimental device.
