Problems solved by technology

For this type of setting, there must be space for the electric heating element to be inserted and inserted in the lower part, and there must be space for the arrangement of the curved wave tube. Under the premise that the space at the bottom is tight, such an arrangement of the electric heating element and the system connection pipe is not conducive to the overall performance.

Embodiment 1

[0036] This embodiment proposes a voltage stabilizer structure in which the system nozzle and the upper part of the electric heating element are centrally arranged. The structure includes a cylinder 1, an electric heating element 2 and a nozzle assembly; wherein, the electric heating element and the nozzle assembly are arranged on the upper part of the cylinder.

[0037] Compared with the existing general voltage stabilizer structure, the present invention simplifies the layout requirements and difficulty of the lower voltage stabilizer by centrally arranging the electric heating element and the system takeover on the upper part of the voltage stabilizer, and at the same time, the pressure control and volume compensation of the system can be realized. function, the present invention optimizes the overall performance of the system.

[0038] Specifically in this embodiment, as Figure 1-3 As shown, the structure of the voltage stabilizer is a cylindrical cylindrical structure. ...

Embodiment 2

[0042] The system takeover and the pressure stabilizer structure centrally arranged on the upper part of the electric heating element proposed in the above embodiment 1 are used in the pressure safety system connected with the nuclear reactor system, so as to realize the pressure safety control of the nuclear reactor coolant system.

[0043] When the system needs to heat up and generate a steam chamber, the electric heating element 2 is activated, and the water supply pipe 4 is continuously filled with water. Due to the heating effect of the electric heating element 2 in the water tank 3, the temperature of the medium inside the pressure stabilizer rises and the volume increases, and the wave pipe 5 drains water to the reactor coolant system; at the same time, steam is continuously generated inside the pressure stabilizer cylinder 1, and the system steam vapor is established. cavity. When the system needs to cool down and eliminate the steam cavity, it is completed through the...

Embodiment 3

[0045] The system connection pipe and the pressure stabilizer structure centrally arranged on the upper part of the electric heating element proposed in the above embodiment 1 can also be applied to the pressure safety system connected with the high temperature and high pressure systems in other technical fields to realize the pressure safety control.

[0046] As will be appreciated by those skilled in the art, the embodiments of the present application may be provided as a method, a system, or a computer program product. Accordingly, the present application may take the form of an entirely hardware embodiment, an entirely software embodiment, or an embodiment combining software and hardware aspects. Furthermore, the present application may take the form of a computer program product embodied on one or more computer-usable storage media having computer-usable program code embodied therein, including but not limited to disk storage, CD-ROM, optical storage, and the like.

Abstract

The invention discloses a voltage stabilizer structure with a system connecting pipe and an electric heating element centrally arranged on the upper portion and an application of the voltage stabilizer structure. The structure comprises a barrel, an electric heating element and a connecting pipe assembly. The electric heating element and the connecting pipe assembly are both arranged at the upperpart of the cylinder body. The system connecting pipe and the electric heating element are centrally arranged on the upper portion of the voltage stabilizer structure, the middle-lower portion structure of the voltage stabilizer is integrally optimized, the arrangement requirement and difficulty of the bottom of the voltage stabilizer are simplified, space integration is achieved, arrangement of the whole nuclear power system is optimized, and then the performance of the whole system is optimized. The voltage stabilizer structure is wide in application range and can also be applied to high-temperature and high-pressure systems in other fields.

Description

technical field [0001] The invention relates to the technical field of high temperature and high pressure, and is particularly suitable for the technical field of nuclear reactors, in particular to a voltage stabilizer structure in which a system takeover and an upper part of an electric heating element are centrally arranged. Background technique [0002] In the nuclear reactor system, the pressure fluctuation of the reactor coolant system is controlled by the pressure safety system. The regulator is the key equipment of the pressure safety system. In conventional nuclear power plants, the lower part of the regulator is saturated water and the upper part is saturated steam. Several electric heating elements are inserted in the lower part of the voltage stabilizer, which are used as heating equipment for generating steam chamber. The bottom of the voltage stabilizer is provided with a wave tube which is connected with a loop of the reactor coolant system as a channel for co...
