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 connecting pipe and the upper part of the electric heating element are collectively arranged, and the structure includes a cylinder body 1, an electric heating element 2 and a connecting pipe assembly; wherein, the electric heating element and the connecting pipe assembly are arranged on the upper part of the cylinder body.

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

[0038] Specifically in this embodiment, as Figure 1-3 As shown, the regulator structure is a cylindric...

Embodiment 2

[0042] The pressure stabilizer structure with the system connection and the upper part of the electric heating element proposed in the above-mentioned embodiment 1 is used in the pressure safety system connected with the nuclear reactor system to realize the pressure safety control of the nuclear reactor coolant system.

[0043] When the system needs to heat up and generate a steam cavity, the electric heating element 2 is started, and the water supply connecting pipe 4 is continuously injected 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 pressurizer rises and the volume increases, and the wave pipe 5 drains water to the reactor coolant system; at the same time, the inside of the pressurizer cylinder 1 continuously generates steam to establish a system steam cavity. When the system needs to cool down and eliminate the steam cavity, it can be completed through the joint action of the water ...

Embodiment 3

[0045] The above-mentioned embodiment 1 proposes a pressure stabilizer structure in which the system connection and the upper part of the electric heating element are centrally arranged, and can also be applied to a pressure safety system connected to a high temperature and high pressure system in other technical fields to realize pressure safety control.

[0046] Those skilled in the art should understand that the embodiments of the present application may be provided as methods, systems, or computer program products. 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 including but not limited to disk storage, CD-ROM, optical storage, etc., having computer-usable program code embodied therein.

Description

technical field [0001] The invention relates to the technical field of high temperature and high pressure, is particularly suitable for the technical field of nuclear reactors, and in particular relates to a voltage stabilizer structure in which the system connection pipe and the upper part of the 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 pressurizer is the key equipment of the pressure safety system. In a conventional nuclear power plant, the lower part of the pressurizer is saturated water, and the upper part is saturated steam. Several electric heating elements are inserted in the lower part of the voltage stabilizer as a heating device for generating steam chamber. There is a wave tube at the bottom of the pressurizer which is connected to a loop of the reactor coolant system as a channel connecting w...
