Abstract
The utility model relates to a kind of power transformer flow relay vacuum on-line measuring device.The flow relay of power transformer to be sealed with oil tank of transformer by oil pipe one end and communicates, the other end seals with conservator and communicates, fixing threeway is sealed between described flow relay and conservator, last interface of threeway to be sealed with one end of flow monitoring device by valve and communicates, and the other end of flow monitoring device seals with vacuum generating device and communicates.Its structure is simple, and on-line monitoring is time saving and energy saving.
Description
Technical field
The utility model belongs to power transformer field, particularly a kind of power transformer flow relay vacuum on-line measuring device.
Background technology
Along with developing rapidly of country, the main equipment power transformer that electrical network uses gets more and more, and transformer is then in electric system, and not only crucial but also valuable main equipment, its proterctive equipment is flow relay.Flow relay is arranged between the fuel reserve tank of transformer and conservator, not quick detachable, and gas flow speed relay must regularly detect it, and the equipment detecting flow velocity is huge, can not at the scene, so flow relay detects once, very difficult.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of power transformer flow relay vacuum on-line measuring device, and its structure is simple, and on-line monitoring is time saving and energy saving.
The technical scheme in the invention for solving the technical problem is: the flow relay of power transformer to be sealed with oil tank of transformer by oil pipe one end and communicates, the other end seals with conservator and communicates, fixing threeway is sealed between described flow relay and conservator, last interface of threeway to be sealed with one end of flow monitoring device by valve and communicates, and the other end of flow monitoring device seals with vacuum generating device and communicates.
The utility model structure is simple, and on-line monitoring is time saving and energy saving.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model front view;
Fig. 2 is the A place enlarged drawing in the utility model Fig. 1.
Embodiment
As shown in Figure 1, 2, the vacuum flow relay 6 of power transformer to be sealed with oil tank of transformer 8 by oil pipe 7 one end and communicates, the other end seals with conservator 1 and communicates, fixing threeway 5 is sealed between described flow relay 6 and conservator 1, last interface of threeway 5 to be sealed with one end of flow monitoring device 3 by valve 4 and communicates, and the other end of flow monitoring device 3 seals with vacuum generating device 2 and communicates.
Described valve 4 is butterfly valve.
When power transformer normally uses, valve-off 4.When needing to detect flow relay 6, open valve 4, start vacuum generating device 2, flow monitoring device 3 can detect flow relay 6.
