Drawings
Fig. 1 is a structural diagram of a distribution website fault early warning device provided by an embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In order to explain the technical solution of the present invention, the following description is made by using specific examples.
Fig. 1 shows the structure of the distribution website fault early warning device provided by the embodiment of the present invention, and only the parts related to the embodiment of the present invention are shown for convenience of description.
As shown in fig. 1, the distribution website fault early warning device provided in this embodiment includes a housing 1 and a gas collecting pipe 2 located at the top of the housing 1, two gas tanks 3 and a two-way gas valve 4 are arranged in the housing 1, a sulfur hexafluoride gas sensor 31 and a 32 pressure gauge are inserted into each gas tank 3, each gas tank 3 is configured with a gas pump 5, each gas tank 3 includes a gas inlet pipe 33 and a gas outlet pipe 34, the gas pump 5 is located on the gas inlet pipe 33 on the corresponding side, the gas outlet pipes of the two gas tanks 3 are connected to the two-way gas valve 4, the gas collecting pipe 2 is provided with a plurality of alignment holes 21, two ends of the gas collecting pipe 2 are connected to a bent pipe 6, the bent pipe 6 enters the housing 1 and is connected to the gas inlet pipe 33 on the corresponding side, the top of the housing 1 is further provided with a control board 7, the, The air pump and the two-way air valve 4 are connected to the control panel 7.
The device has the following working procedures:
the device is installed in sulfur hexafluoride electrical equipment or directly placed in a station room, and mounting seats 8 are arranged on two sides of the shell. The two inflation pumps work, air enters the air tank through the air collecting pipe, the bent pipe and the air inlet pipe, a circle of filter screen is arranged in the air collecting pipe in order to guarantee air inlet cleanliness, and the filter screen is used for filtering impurities such as dust in the air. The air is divided into two paths and is pumped into the two air tanks, the air tanks continuously rise, when the pressure gauge detects that the pressure in the air tanks reaches a preset pressure value, the control panel controls the sulfur hexafluoride gas sensor to detect sulfur hexafluoride gas in the air tanks, and the compressed gas is in the air tanks, so that the concentration of sulfur hexafluoride in the air tanks can be improved, and the sulfur hexafluoride gas sensor can detect the sulfur hexafluoride gas more easily.
