The invention relates to the technical field of power utilization protection of a nuclear power plant, and provides a grounding protection method and system for supplying power by multiple paths of power supplies with different grounding modes. A resistance grounding mode is adopted for a main transformer of a power supply outside a plant and a low-voltage side neutral point of a self-contained generator in the plant, so that fault current flowing through a fault point not only comprises capacitance current, but also comprises capacitance current; the system further comprises a grounding resistance current, so that a grounding fault can be easily detected through the zero sequence current transformer, and a specific loop where the grounding fault is located can be more easily judged. After a grounding fault occurs, the grounding resistor is switched off through the neutral point grounding resistor switch, so that the magnitude of grounding fault current can be quickly reduced, and the impact of the current on system equipment is reduced. The grounding resistor provides a current limiting function at the initial stage of a fault, and after the grounding resistor is disconnected, channels for fault current to flow are further reduced, so that the fault influence is reduced to the minimum.

The utility model sets up sulfur adding kettle, and sets up electric heating rod in sulfur adding kettle, can utilize high temperature and promote the activation of sulfur, avoid the production of mercaptan of elemental sulfur and olefin, thereby reduce the generation of harmful gas.

The utility model relates to the technical field of flow regulating valves, in particular to a gas pipeline flow regulating device, a knob drives a transmission rod to rotate, the transmission rod drives a gear to rotate, and due to the fact that the gear is meshed with two racks, when the gear rotates, the racks drag a valve element to slide in a sealing shell, and the sealing shell is sealed. When the two valve elements slide outwards at the same time, more communicating holes can be blocked, the space for containing fuel gas in the sealing shell is reduced, channels for fuel gas to flow are reduced, and when the valve elements slide inwards, more communicating holes can be communicated with the containing space in the sealing shell, and when air enters the sealing shell, the air is in contact with the valve elements before being in contact with the valve elements, so that the sealing shell is more smooth. When colliding with the valve element, the fuel gas flows in the opposite direction and collides with the entering fuel gas, the rest of the fuel gas flows out along the communicating hole, and therefore the flow speed of the fuel gas is reduced, the flow speed of the fuel gas is reduced through the backflow effect generated after the fuel gas collides with the valve element, and the effect of avoiding fuel gas leakage caused by connection disengagement is achieved.
