Problems solved by technology

Most of the boards are installed in the cabinets of the steam turbine workshop, the ambient temperature is high, the noise is loud, and the working environment is relatively harsh
In addition, the internal space of the KRG cabinet (centralized control analog cabinet) where the boards are located is narrow and the lighting is insufficient, and the distance between adjacent CT (printed circuit board) boards is relatively close or even close to each other, which can easily cause equipment to touch by mistake
When calibrating the thermocouple channel, the signal generator is usually used to fix the temperature compensation method, and switching the cabinet door on site or the operation of the air conditioner affects the compensation temperature, which will also bring a lot of trouble to the temperature channel calibration

Embodiment 1

[0032] This embodiment provides a nuclear power plant panel calibration system. The nuclear power plant panel calibration system is mainly used for off-site calibration of the panels in the steam turbine workshop cabinet of the nuclear power plant, that is, calibration is performed at a non-production site, which can avoid nuclear power plants. The complex and inconvenient environment of the factory production site.

[0033] The SC7400 series board in the steam turbine plant cabinet of the nuclear power plant is a software-configurable single-input signal processing board. There are 5 types of boards as shown in Table 1 below, and the available output types of each type are fixed.

Embodiment 2

[0051] This embodiment provides a verification method for nuclear power plant boards. In this nuclear power plant board verification method, the verification is completed by the nuclear power plant board verification system in the first embodiment.

[0052] Such as Figure 5 As shown, the verification method for nuclear power plant panels in this embodiment mainly includes the following steps:

[0053] S101: install;

[0054] Insert 10 boards into the slots of the calibration cabinet, and connect the 10 boards to the power supply through the positive connection terminal and negative connection terminal of the power supply respectively, and complete the installation preparation work before acceptance.

[0055] S102: power on;

[0056] The 10 boards are powered on, and the power supply provides 24V DC. Observe the power status indicator light on the board. If the power indicator (POWER) on the board is on, the circuit inside the board is normal, and the power-on verification i...

Embodiment 3

[0065] This embodiment provides a nuclear power plant board verification method. On the basis of the second embodiment above, a configuration setting step is added to meet the board verification required by the configuration.

[0066] Such as Figure 6 As shown, the verification method for nuclear power plant panels in this embodiment includes the following steps:

[0067] S201: install;

[0068] Insert 10 boards into the slots of the calibration cabinet, and connect the 10 boards to the power supply through the positive connection terminal and negative connection terminal of the power supply respectively, and complete the installation preparation work before acceptance.

[0069] S202: power on;

[0070] The 10 boards are connected to the power supply, and the power supply provides 24V direct current. Observe the power status indicator light on the board. If the power indicator light of the board is not on, there is a short circuit or short circuit problem in the board, and...

Abstract

The invention relates to the technical field of equipment debugging of a nuclear power generation system, and specifically discloses a nuclear power station plate verification system and verificationmethod thereof. The system includes a verification cabinet, a power supply and a signal input unit; the verification cabinet is provided with multiple slots used for installing plates; the power supply has multiple positive connection terminals and negative connection terminals used for connecting to the positive and negative terminals of the plates; and the signal input unit has a signal output end used for connecting to the input ends of the plates, and is used for inputting signals into the plates to perform verification. As the system can verify the line conduction and input and output ofthe plates, the plates do not need to be verified under the complex environmental conditions at nuclear power station site; the plates can be conveniently verified in other places, and the efficiencyand accuracy of verification are higher without the influences of small space and high temperature; and a testing stand can simultaneously verify multiple plates, and thus, verification efficiency canbe further enhanced, and demands of a large-scale nuclear power station can be met.

Description

technical field [0001] The invention relates to the technical field of equipment debugging of a nuclear power plant power generation system, and in particular to a nuclear power plant panel checking system and a checking method thereof. Background technique [0002] A nuclear power plant, also known as a nuclear power plant, is a power plant that uses the energy released by nuclear fission (Nuclear Fission) or nuclear fusion (Nuclear Fusion) reactions to generate electricity. Nuclear power plants currently in commercial operation use nuclear fission reactions to generate electricity. Nuclear power plants are generally divided into two parts: nuclear islands that use nuclear fission to produce steam (including reactor devices and primary loop systems) and conventional islands that use steam to generate electricity (including turbogenerator systems). The fuel used is generally radioactive heavy metals: uranium, plutonium. [0003] The energy released during the fission proce...
