Abstract
The utility model discloses a body nitrogen filling and pressure monitoring device for a transformer or a reactor, which comprises a cover, a pressure gauge and a plug. The lower end of the cover is fitted with an evacuation connector of the transformer or the reactor, the pressure gauge is mounted at an opening arranged on the upper end face of the cover, and a nitrogen filling connector is arranged on the side wall of the cover. When nitrogen is not filled, the plug is tightly plugged into the nitrogen filling connector to seal the connector. When nitrogen is filled, the nitrogen filling connector is connected with a nitrogen supply device. The nitrogen filling connector and the pressure gauge are disposed on the same device, and convenient to mount and dismount.
Description
Technical field
The utility model belongs to power transformer and makes the field, relates to the main body leak test operation of a kind of power transformer or reactor and the main body in the transportation and fills nitrogen and pressure monitoring device.
Background technology
Power transformer and reactor for avoiding the fuel tank seepage, are the preventer tide of experiencing in the main body transportation in manufacture process, need carry out the pressure leak test and fill pressure monitoring in the nitrogen transportation.And on oil tank of transformer, do not have special-purpose nitrogen joint and a pressure monitoring position filled, and need and fill the nitrogen joint at the different position setting pressure table of fuel tank, waste time and energy, operate very inconvenient.
Summary of the invention
The utility model solves the above-mentioned problems in the prior art exactly, provides the transformer that a kind of gas-charging connection and tensimeter be integrated in one or the main body of reactor to fill nitrogen and pressure monitoring device.
For addressing the above problem, technical solution of the present utility model is: the main body of a kind of transformer or reactor is filled nitrogen and pressure monitoring device, and it comprises lid, tensimeter and the stopper that interface is complementary that vacuumize of bottom and transformer or reactor; Have mouth on the upper surface of lid, on mouthful tensimeter is installed, the nitrogen of filling interface is arranged on the sidewall, when not inflating, the nitrogen interface is filled in the sealing of stopper jam-pack, during inflation, fills the nitrogen interface and connects the nitrogen feedway.
During use, the utility model is installed to vacuumizing on the interface of transformer or reactor oil tank top, during inflation, open the stopper on the lid, install the gas-charging connection of nitrogen feedway, open the valve that the case top vacuumizes interface, begin inflation, gas replenishment process is the detected pressures gauge pressure simultaneously, stops inflation after reaching the pressure requirement, closes the valve that vacuumizes interface, pull down gas-charging connection, reinstalled stopper, opened the valve that vacuumizes interface, can realize the monitoring under leak test and the travel position by manometric reading.The utlity model has following advantage: fill nitrogen interface and tensimeter and be arranged on the same device, be convenient to installation, disassembling section.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
As shown in Figure 1, present embodiment comprises lid 1, tensimeter 2 and the stopper that interface Φ 80 butterfly valve mouths are complementary that vacuumize of bottom and transformer or reactor.Have mouth on the upper surface of lid 1, on mouthful tensimeter 2 is installed, the nitrogen of filling interface 3 is arranged on the sidewall, when not inflating, nitrogen interface 3 is filled in the sealing of stopper jam-pack, during inflation, fills nitrogen interface 3 and connects the nitrogen feedway.
