Seal run-through structure for extracting electric cables from enclosed container

Abstract

The invention discloses a seal run-through structure for extracting electric cables from a enclosed container, wherein the seal run-through structure for extracting electric cables from the enclosed container comprises a guide pipe for extracting electric cables and a pressing plate which is pressed outside an outer baffle plate; the inner end of the guide pipe is communicated with the enclosed container; a flange disk is fixed on the outer end of the guide pipe; the guide pipe is also internally provided with an inner baffle plate; the pipe opening of the outer end of the guide pipe is provided with the outer baffle plate; the pressing plate and the flange disk are connected through a bolt; the inner baffle plate, the outer baffle plate and the pressing plate are all provided with through holes for running through by the electric cables; and seal glue is filled between the inner baffle plate and the outer baffle plate. According to the invention, a run-through element is not required to be pre-manufactured, the electric cables are not required to be connected, after the electric cables directly run through, under the environment temperature, the seal glue can be adopted for pouring and curing on the spot so as to achieve the seal run-through effect, and the seal run-through structure for extracting electric cables from the enclosed container is convenient and rapid to use, and the seal run-through structure for extracting electric cables from the enclosed container provided by the invention has good adaptability, and is low in using cost.

Description

technical field [0001] The invention relates to a cable lead-out device, in particular to a sealed penetration structure for leading out cables from a closed container. Background technique [0002] In many practical application situations, it is necessary to lead the cable into (lead out) the airtight container, and at the same time ensure that the sealing performance of the airtight container will not be damaged. Especially in the case of high pressure inside the container, it is difficult to ensure the sealing penetration of the cable outlet. [0003] For example, the cables used in nuclear power plants have to pass the LOCA (simulated loss of coolant accident) test, and the relevant performance of the cables needs to be tested under the conditions of high temperature, high pressure and chemical corrosion. The cable LOCA test is carried out in the test chamber under high temperature and high pressure. At the same time, the cable needs to be led out of the test chamber to...

Problems solved by technology

The disadvantage of this method is that it has poor versatility. When the number and specifications of the penetration cables change, it is necessary to prefabricate the penetration parts again, and the cable penetration cannot be quickly realized at the construction site, and the manufacturing cost is relatively high.
