Abstract
The utility model discloses an air-pressure monitoring device of a sulfur hexafluoride gas insulating current transformator, and aims to provide the air-pressure monitoring device which can clearly, conveniently and accurately observe a current transformator. The air-pressure monitoring device comprises a transformator base, a gas pipe and a gas density controller, and is characterized in that one end of the gas pipe is communicated with the gas density controller through an inverted valve, the other end of the gas pipe is communicated with the transformator base through another inverted valve, and the gas density controller is welded on the lower part of a bracket through a fixed seat. The utility model is mainly used for air-pressure monitoring of the sulfur hexafluoride gas insulating current transformator.
Description
Technical field
The utility model relates to a kind of air pressure monitoring device, relates in particular to a kind of sulfur hexafluoride gas-insulating current transformer air pressure monitoring device.
Background technology
A very important performance of SF 6 high-voltage electric equipment products is exactly its sealing property, sulfur hexafluoride gas is as the major insulation medium of product, to product hermeticity can the air pressure of long-term reliability, product whether normal, whether determining the product insulating property, directly having influence on product can safe operation.So, for the user, grasp the barometric information of product in service, be the requisite important process of daily monitoring.For ease of Pressure monitoring, every product has all been installed the sulfur hexafluoride gas density controller with auto thermal compensation function, and when mutual inductor leaks, when air pressure was reduced to alarm set point, density controller just sent warning, by the timely tonifying Qi of user notification producer.Therefore, how clear, observe the gas density controller indication situation of (claiming densitometer again) easily and accurately, be exactly subject matter to be solved in the utility model, because mutual inductor is an outdoor products, the product height is above 3 meters, will be at height like this, the position of having only 10 centimeters glass dial plate to see pointer clearly through diameter is difficult.
Summary of the invention
The purpose of this utility model be to provide a kind of energy clear, observe the densitometric device of current transformer, i.e. air pressure monitoring device easily and accurately.
For achieving the above object, technical solution of the present utility model is: guide densitometer into overhead about 1.5 meters height from the high position more than 3 meters by tracheae, the height basic and human eye adapts, like this, the floor manager just can just can directly not observe densitometric indication situation by any instrument.
The utility model comprises mutual inductor base, tracheae and gas density controller, it is characterized in that: an end of described tracheae 5 is communicated with gas density controller 6 by reverse checkvalve 2, the other end is by reverse checkvalve 2 ' be communicated with mutual inductor base 3, and gas density controller 6 then is welded on the bottom of support 1 by holder 4.
The utility model has the advantages that: by tracheae, reverse checkvalve and holder, gas density controller (densitometer) is displaced to overhead about 1.5 meters height from the height more than 3 meters, can not be timely thereby solved, accurately find densitometer indication situation, control whether current transformer leaks and the drawback of tonifying Qi in time.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1-support, 2,2 '-reverse checkvalve, 3-mutual inductor base, 4-holder, 5-tracheae, 6-gas density controller, 7-mutual inductor.
Embodiment
Below in conjunction with accompanying drawing the utility model and embodiment thereof are described in further detail.
Referring to accompanying drawing, the utility model comprises mutual inductor base, tracheae and gas density controller, it is characterized in that: an end of described tracheae 5 is communicated with gas density controller 6 by reverse checkvalve 2, the other end is by reverse checkvalve 2 ' be communicated with mutual inductor base 3, and gas density controller 6 then is welded on the bottom of support 1 by holder 4.
Earlier with the upper end of tracheae 5 by reverse checkvalve 2 ' be communicated with mutual inductor base 3, (being full of sulfur hexafluoride gas in the base), the other end with tracheae 5 is communicated with density controller (densitometer) 6 by reverse checkvalve 2 again, and densitometer 6 is welded on the bottom of support 1 by holder 4.
Adopt the tracheae 5 of teflon (plastics king) gas density controller (densitometer) 6 to be caused overhead about 1.5 meters height so that the floor manager can just can directly not observe densitometric indication situation by any instrument, elbow employing stainless steel bend and detachable self-styled reverse checkvalve 2,2 ', the pedestal of densitometer 6 adopts the demountable structure of bolt, be welded on the bottom of support 1 again by holder 4, draw the position exposed parts under from mutual inductor base 3 to tracheae and all be encapsulated in the wire casing with the secondary cable line, attractive in appearance to guarantee.
