Detailed Description
This embodiment uses through pressure controller and heating fan cooperation, and sulfur hexafluoride gas pressure obtains promoting in the gas cylinder through continuous heating messenger in the gas cylinder, satisfies to aerify required pressure for equipment. The pressure controller automatically controls the heating amount of the wind-heat fan, so that the sulfur hexafluoride in the sulfur hexafluoride gas cylinder is fully utilized, and the utilization rate of each sulfur hexafluoride gas cylinder is greatly improved. Meanwhile, the air pollution caused by the emission of SF6 gas is relieved.
In the embodiment, the pressure control device is D504/7DZ, and when the measured pressure of the sulfur hexafluoride gas cylinder is lower than the rated value, the low contact of the pressure control device is connected with the coil loop of the relay, so that the relay is closed, and the air heater starts to work.
The heating quantity of the heating fan is controlled according to the pressure in the gas cylinder, so that the pressure in the gas cylinder is higher than that of inflation equipment, when the pressure in the sulfur hexafluoride gas cylinder meets the inflation pressure for combined electrical appliances, the pressure controller is not started, the heating fan cannot be switched on, the sulfur hexafluoride gas cylinder can meet the inflation requirement pressure for the equipment by depending on the original factory filling pressure, when the pressure in the gas cylinder is lower (such as 0.2 MP), the pressure controller is started, the heating fan is started when a contact is closed, the pressure in the gas cylinder is continuously increased, the level that the pressure in the gas cylinder is higher than the pressure of the sulfur hexafluoride gas of the electrical appliances (about 0.4 MP) is ensured, and the sufficient application of.
In the implementation, in the process of inflating the electrical equipment by the gas cylinder, the gas pressure of 0.3MP is connected with the contactor coil (the pressure controller is opened), and the contactor coil is disconnected when the gas reaches 1.1MP (the pressure controller is disconnected).
