Description
Technical field
The utility model relates to transformer, particularly the pick-up unit of oil level gauge for transformer.
Background technology
Power transformer is one of major equipment of generating plant and electric substation.The effect of transformer is many-sided, boosted voltage electric energy can not only be delivered to electricity consumption area, voltage can also be reduced to use voltage at different levels, to meet the needs of electricity consumption.
In oily formula transformer, need the pressure detecting transformer oil in real time.When pressure is through threshold value, need pressure release.Usual way is: install oil level indicator, and installs blowdown valve on oil level indicator top, and when the pressure of transformer oil exceedes threshold value, blowdown valve is opened, and reduces the pressure of transformer oil.Visible, in order to improve serviceability, need to detect described blowdown valve, to make to open when the pressure of regulation.Current way is: detect blowdown valve separately, and this way has deficiency, as:
1, detection efficiency is low, needs blowdown valve one by one to detect separately;
2, the serviceability of whole oil level gauge for transformer is not detected, as impermeability, insufficiency face.
Utility model content
In order to solve above shortcomings in prior art, the utility model provides that a kind of detection efficiency is high, structure is simple, the pick-up unit of the oil level gauge for transformer of complete function.
For achieving the above object, the utility model is by the following technical solutions:
A pick-up unit for oil level gauge for transformer, the top of described oil level indicator arranges blowdown valve; Described pick-up unit comprises:
First airtight container, described oil level gauge for transformer is suitable for being arranged on described first airtight container and inside and is communicated with;
Pressure transducer, described pressure transducer is arranged on described first airtight container;
Compression module, described compression module is by the first airtight container described in pipeline communication.
According to above-mentioned pick-up unit, alternatively, described pick-up unit comprises further:
Support, described first airtight container is installed on the bracket by rotating shaft;
Second container, described second container upper opening, is arranged on the bottom of described first airtight container.
According to above-mentioned pick-up unit, preferably, described pressure transducer is arranged on described pipeline.
Compared with prior art, the beneficial effect that the utility model has is:
1, on the first airtight container, at least two oil level indicators are installed, the serviceability of multiple oil level indicator can be detected simultaneously, and adjusted, meet the demands to make oil level indicator;
2, only need to arrange airtight container, compression module and pressure transducer, the serviceability of the blowdown valve on oil level indicator top can be detected: whether can open when the pressure specified; Structure is simple, cost is low, and detects accurately;
3, when oil level indicator is turned in second container, oil level indicator can be detected and whether leak, also namely detect sealing effectiveness, complete function.
