Description
Technical field
The utility model provides a kind of sulfur hexafluoride humidity sensor accuracy pick-up unit, belongs to sulfur hexafluoride gas Humidity Detection instrument technology.
Background technology
SF
6gas, owing to having good insulation characterisitic and arc quenching characteristic, is used widely in high voltage electric equipment.Due to SF
6gas is manufactured the factors such as link, electrical equipment manufacture and installation process, equipment leakage, adsorbent, causes SF
6in gas, moisture increases, thereby insulant inside surface generation arcing fault probability is increased; Isolating switch, owing to making moist or producing condensation, makes its decreasing insulating; SF
6in gas, moisture can participate in SF
6the decomposition reaction of gas, generates the extremely strong decomposition product of corrosivity, and then the interior metal original paper of corrosion electrical equipment and sealed insulating material, shortens the serviceable life of electrical equipment.
Along with the development of domestic intelligent grid, in a large amount of electrical equipments, SF is installed at present
6gas humidity device for detecting density, this type of monitoring device major part is the monitoring device of external, measuring accuracy is relatively low, and the impact that is vulnerable to pressure causes measurement accuracy to reduce.
Utility model content
The purpose of this utility model is to provide that a kind of measuring accuracy is high, a kind of sulfur hexafluoride humidity sensor accuracy pick-up unit of excellent working performance.Its technical scheme is:
A kind of sulfur hexafluoride humidity sensor accuracy pick-up unit, it is characterized in that: comprise tank body, mirror surface type sulfur hexafluoride humidity sensor, RC sulfur hexafluoride humidity and compactibility sensor, motor, magnetic shaft coupling and be arranged on the fan in tank body, wherein tank body is provided with safety valve, tensimeter, vacuum meter, air intake opening, gas outlet and for the adapter of sulfur hexafluoride humidity sensor to be detected is installed, mirror surface type sulfur hexafluoride humidity sensor and RC sulfur hexafluoride humidity and compactibility installation of sensors are in inner tank wall, gas outlet connects dew point hygrometer through valve, magnetic shaft coupling is inlaid on tank body, the outer rotor of magnetic shaft coupling is connected with the output shaft of motor, internal rotor is fixedly connected with fan.
Described a kind of sulfur hexafluoride humidity sensor accuracy pick-up unit, the interface that sulfur hexafluoride humidity sensor to be detected is installed is 2-4.
Its principle of work is: first sulfur hexafluoride humidity sensor to be detected is installed on tank body through adapter.When detection, first by the nitrogen that is filled with certain humidity in tank body to set pressure, unlatching electric motor fan rotates, make nitrogen humidity equilibrium in tank body, humidity and the density of reading nitrogen in tank body by mirror surface type sulfur hexafluoride humidity sensor and RC sulfur hexafluoride humidity and compactibility sensor, then analyze the output valve of sulfur hexafluoride humidity sensor to be detected, and contrast with the humidity of reading and density, to judge the accuracy of sulfur hexafluoride humidity sensor to be detected.
The utility model compared with prior art, its advantage is: owing to adopting mirror surface type sulfur hexafluoride humidity sensor, RC sulfur hexafluoride humidity and compactibility sensor to being analyzed by the accuracy of measurement of check sensor simultaneously, accuracy of detection is high, and analysis speed is fast.
