Description
Technical field
It the utility model is related to transformer field, and in particular to a kind of insulating oil supplementary device.
Background technology
220 kilovolts of high-voltage mutual inductors, which are that paper condenser is hermetically sealed, clamps nitrogen charging structure, and the oil conservater of its upper top has again
0.02-0.08MP nitrogen, to ensure to keep normal pressure inside transformer.Required according to power test, each some cycles need
Will from transformer bottom sampling valve take out transformer oil carry out sample detection, although have when dispatching from the factory in transformer enough oil masses and
Nitrogen pressure, but accumulation taking-up oil samples are excessive in longtime running, reduce its oil level, nitrogen pressure in upper top oil conservater
Power declines, or even forms negative pressure, potential safety hazard be present.
Utility model content
In view of this, the application provides a kind of insulating oil supplementary device, has the function of being automatically replenished nitrogen and insulating oil,
With security performance it is high the advantages of.
To solve above technical problem, technical scheme provided by the utility model is a kind of insulating oil supplementary device, including
Fuel tank, the fuel tank side are provided with insulating oil liquid level sensor and nitrogen pressure sensor, and the fuel tank side is provided with repairing mouth,
The repairing mouth is connected with insulating oil fluid infusion electric control gear, and the insulating oil fluid infusion electric control gear includes control system and connection is controlled
The sealant supplement cylinder of system processed, electrical ball valve is provided between the control system and repairing mouth.
Preferably, the insulating oil liquid level sensor and nitrogen pressure sensor electrically connect the control system.
Preferably, the fuel tank upper end is connected with nitrogen filling-valve.
Preferably, the fuel tank lower end is provided with insulating oil filling-valve.
Compared with prior art, its detailed description is as follows by the application：
Insulating oil liquid level sensor and nitrogen pressure sensor, the nitrogen pressure are provided with fuel tank disclosed herein
Force snesor and insulating oil liquid level sensor electrically connect the control system in the insulating oil fluid infusion electric control gear, work as nitrogen pressure
When the measured value of sensor or insulating oil liquid level sensor is less than setup pressure value, the insulating oil fluid infusion electric control gear opens electricity
Dynamic ball valve, into fuel tank, supplementary insulation oil is until nitrogen pressure and insulating oil liquid level meet setting value.
The application has automatic filling insulating oil, and holding nitrogen pressure is constant, ensures that insulation oil mass meets design requirement
Function, there is the advantages of having a safety feature.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with the accompanying drawings and have
The utility model is described in further detail for body embodiment.
As shown in figure 1, a kind of insulating oil supplementary device, including fuel tank 1, the upper end of the side of fuel tank 1 are filled out provided with nitrogen
Valve 2 is filled, the lower section of the side of fuel tank 1 is provided with insulating oil filling-valve 3, and the side of fuel tank 1 is additionally provided with the He of insulating oil liquid level sensor 4
Nitrogen pressure sensor 5, the side of fuel tank 1 are provided with repairing mouth, and the repairing mouth is connected with electrical ball valve 6, the electric ball
Valve 6 is connected with insulating oil fluid infusion electric control gear, and the insulating oil fluid infusion electric control gear includes electric-control system and sealant supplement cylinder, described
Electrical ball valve 6 connects the control system 7, and the control system connects the sealant supplement cylinder 8, and the control system 7 electrically connects absolutely
Edge fluid level sensor 4 and nitrogen pressure sensor 5.
The fuel tank upper end is connected with nitrogen filling-valve, and the fuel tank upper end is provided with insulating oil filling-valve, fills insulating oil
Before, the fuel tank has been passed through nitrogen by nitrogen filling-valve, because the density of nitrogen is less than atmospheric density, therefore the nitrogen
When being passed through fuel tank, first on float over above fuel tank, the nitrogen filling-valve for being arranged on fuel tank upper end is advantageous to nitrogen filling and air
Discharge, the insulating oil filling-valve 3 for being arranged on lower end are advantageous to oily slowly filling fuel tank, avoided caused by pouring fuel tank from top
Insulating oil internal mix has a large amount of gases, influences the dielectric properties of insulating oil.
Insulating oil liquid level sensor and nitrogen pressure sensor, the nitrogen pressure are provided with fuel tank disclosed herein
Force snesor and insulating oil liquid level sensor electrically connect the control system in the insulating oil fluid infusion electric control gear, work as nitrogen pressure
When the measured value of sensor or insulating oil liquid level sensor is less than setup pressure value, the insulating oil fluid infusion electric control gear opens electricity
Dynamic ball valve, into fuel tank, supplementary insulation oil is until nitrogen pressure and insulating oil liquid level meet setting value.
The application has automatic filling insulating oil, and holding nitrogen pressure is constant, ensures that insulation oil mass meets design requirement
Function, there is the advantages of having a safety feature.
It the above is only preferred embodiment of the present utility model, it is noted that above-mentioned preferred embodiment should not regard
For that should be defined to limitation of the present utility model, the scope of protection of the utility model by claim limited range.For
For those skilled in the art, do not departing from spirit and scope of the present utility model, can also make some
Improvements and modifications, these improvements and modifications also should be regarded as the scope of protection of the utility model.
