The utility model discloses calibrate or compare when can realize many hand -held type sulfur hexafluoride humidity measuring instrument accurate, high -efficiently, and the fine matching hand -held type sulfur hexafluoride humidity measuring instrument of ability, the gas tightness is strong, and calibration data is accurate.
Description
Technical field
The utility model relates to a kind of hyperchannel calibrating installation of hand-held sulfur hexafluoride moisture instruments.
Background technology
Power industry, in order to ensure the safe and stable operation of sulfur hexafluoride electrical equipment, often needs strictly to detect sulfur hexafluoride gas humidity.In order to ensure to detect the accurate of data, need to calibrate sulfur hexafluoride moisture instruments, conveniently the carrying out of testing, meets the tendency and creates hand-held sulfur hexafluoride moisture instruments, lightlyer than traditional sulfur hexafluoride moisture instruments is easy to operation.But existing sulfur hexafluoride moisture instruments calibrating installation, does not have suitable measurement cavity, adapter and air-channel system etc., well can not mate hand-held sulfur hexafluoride moisture instruments, easily occur that impermeability is not strong, cause calibration data inaccurate.In addition, existing sulfur hexafluoride moisture instruments calibrating installation is also difficult to realize hyperchannel calibration, and can not calibrate multiple stage hand-held sulfur hexafluoride moisture instruments, calibration efficiency is not high, can not realize the synchronous comparison of instrument simultaneously.
Utility model content
Technical problem to be solved in the utility model, just be to provide a kind of hyperchannel calibrating installation of hand-held sulfur hexafluoride moisture instruments, calibration or comparison while it can realize multiple stage hand-held sulfur hexafluoride moisture instruments accurately and efficiently, and well can mate hand-held sulfur hexafluoride moisture instruments, impermeability is strong, and calibration data is accurate.
Solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A hyperchannel calibrating installation for hand-held sulfur hexafluoride moisture instruments, is characterized in that comprising:
One air compressor 1, exsiccator 2 and shunting humidity generator 3 is connected to by tracheae, described shunting humidity generator 3 is connected to precise dew-point hygrometer 4 and some measurement cavitys 5 by tracheae again, described measurement cavity 5 is the stainless steel cylinder of interior smooth, and its one end connects blow-down pipe, the other end is the adapter be connected with described hand-held sulfur hexafluoride moisture instruments 6.
The described adapter be connected with hand-held sulfur hexafluoride moisture instruments uses stainless steel conical gasket to seal.
The gas circuit of described multiple measurement cavity and precise dew-point hygrometer connects the mode adopting parallel shunt.
Principle of work: air compressor provides stable source of the gas, source of the gas, by forming the gas of certain humidity after exsiccator and shunting humidity generator, passes through a precise dew-point hygrometer as reference instrument and multiple measurement cavity in the mode of parallel shunt simultaneously; Hand-held sulfur hexafluoride moisture instruments to be calibrated is connected to cavity to be measured by adapter, can realizes calibrating by the indicating value of comparison as the precise dew-point hygrometer of reference instrument.
Beneficial effect: measuring cavity 5 be the stainless steel cylinder of interior smooth, can make to measure during calibration gas in cavity can good flow, and the humidity in guarantee chamber is even; Adapter uses the sealing of stainless steel conical gasket, and good airproof performance, can meet the alignment requirements of low-moisture conditions; Gas circuit connects the mode adopting parallel shunt, can realize multiple stage hand-held sulfur hexafluoride moisture instruments and calibrate simultaneously, and ensures the accuracy of calibration.
Calibration or comparison while the utility model can realize multiple stage hand-held sulfur hexafluoride moisture instruments accurately and efficiently, and well can mate hand-held sulfur hexafluoride moisture instruments, impermeability is strong, and calibration data is accurate.
Accompanying drawing explanation
Fig. 1 is composition of the present utility model and annexation schematic diagram.
Embodiment
As shown in Figure 1, the hyperchannel calibrating installation embodiment of hand-held sulfur hexafluoride moisture instruments of the present utility model, comprise an air compressor 1, it is connected to exsiccator 2 and shunting humidity generator 3 by tracheae, the mode that shunting humidity generator 3 connects employing parallel shunt by tracheae is again connected to precise dew-point hygrometer 4 and some measurement cavitys 5, measure the stainless steel cylinder that cavity 5 is interior smooth, its one end connects blow-down pipe, the other end is the adapter be connected with hand-held sulfur hexafluoride moisture instruments 6, adapter uses the sealing of stainless steel conical gasket.
